Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of mildew and bacteriostatic agents, and particularly relates to a non-toxic and ecological mildew and bacteriostatic agent, a preparation device and a preparation method. Background Art
[0002] Wood panels are the most commonly used material in home decoration and are widely loved. However, because they are often exposed to various environmental conditions and are susceptible to moisture, mold, and other problems, they require preservative treatment before leaving the factory. Preservatives and antibacterial agents are typically added to the panels to protect them from corrosion and deterioration caused by moisture and mold, which can damage the panels. With increasing environmental awareness, non-toxic, ecological antifungal agents have become the mainstream choice, allowing them to protect wood panels without causing damage to human health.
[0003] Anti-corrosion treatment of wood panels is extremely important, especially in coastal areas where wood panels are in a humid environment all year round, and the anti-corrosion requirements for wood panels are higher. However, when existing non-toxic ecological anti-mildew and antibacterial agents are used to protect wood panels, since the activity of the anti-mildew and antibacterial agents has a certain period of time, once the anti-mildew and antibacterial agents are inactivated, they can no longer protect the wood panels, which makes the wood panels at risk of corrosion due to moisture and mold infection. The panels need to be re-anti-corrosion treated or replaced, which seriously affects people's confidence in the use of wood panels.
[0004] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention
[0005] The purpose of the present invention is to provide a non-toxic ecological mildew and antibacterial agent, a preparation device and a preparation method, which can solve the problem that the antiseptic and antibacterial agent cannot be used to prevent corrosion of wooden boards after its activity is lost.
[0006] In order to achieve the above object, a specific embodiment of the present invention provides the following technical solutions:
[0007] A non-toxic ecological mildew and antibacterial agent includes a filler and a protective layer. The filler is arranged inside the protective layer so that the protective layer can protect the filler, thereby preventing the filler from contacting the outside world. The filler can only contact the outside world when the protective layer is destroyed and exposed to the outside. The filler is a mildew and antibacterial material, which is used to prevent wooden boards from corrosion so that they will not breed mildew in a humid environment, thereby preventing wooden boards from being corroded due to mildew in a humid environment. The protective layer is a corrosion-inhibiting material, which has the ability to slowly decompose in a humid environment. Therefore, when the corrosion-inhibiting material decomposes after a certain period of time, the internal anti-corrosion and antibacterial material can be released. When wood boards are processed, they will be treated with an anti-corrosion agent, and an anti-mildew and antibacterial agent will be sprayed inside the wood boards to prevent the wood boards from forming mold in a humid environment and causing mold and deterioration. However, the activity period of the anti-corrosion and antibacterial agent is limited. When the anti-corrosion and antibacterial agent is inactivated, the wood boards will no longer have the ability to prevent corrosion in a humid environment. When the wood boards are moldy and deteriorate due to mildew, it is usually necessary to replace the boards or perform an anti-corrosion treatment. Therefore, in order to make the anti-corrosion and antibacterial agent in the wood boards active for a long time, an anti-mildew and antibacterial agent prepared from an outer layer of corrosion-inhibiting material and an inner layer of anti-mildew and antibacterial material is evenly arranged inside the wood boards. When used, the corrosion-inhibiting material will decompose within a certain period, thereby releasing the inner anti-mildew and antibacterial material, so that new anti-mildew and antibacterial material is released inside the board, so that the board can be anti-corroded by the released anti-mildew and antibacterial material, thereby achieving the anti-corrosion cycle of the board and extending the service life of the board. The corrosion-inhibiting material is arranged on the outer surface of the anti-mildew and antibacterial material in a wrapped manner to form an anti-mildew and antibacterial agent, so that the corrosion-inhibiting material can well protect the anti-mildew and antibacterial material, ensuring that the anti-mildew and antibacterial material in the corrosion-inhibiting material is stored in a closed environment for a long time, so that the activity of the anti-mildew and antibacterial material will not be affected during storage. Under the action of the corrosion-inhibiting material, the anti-mildew and antibacterial material can be released within the inactivation period of the anti-corrosion material sprayed in the wooden board in the early stage, thereby extending the protection period.
[0008] The mildew-proof and antibacterial material comprises a mildew-proof agent, an antibacterial agent and an additive. The mildew-proof agent is used to prevent mildew on wooden boards, the antibacterial agent is used to inhibit the growth of mildew in wooden boards, and the additive is used to prepare the mildew-proof and antibacterial agent.
[0009] The weight ratio of the mildew inhibitor, antibacterial agent and additive is 10-15:2-2.5:5.5-6.5. The mildew inhibitor, antibacterial agent and additive are mixed evenly and prepared into filler microspheres. In order to make the prepared mildew inhibitor and antibacterial agent material more effective, the mildew inhibitor, antibacterial agent and additive need to be fully stirred evenly by a stirring device during preparation, and then prepared into filler microspheres by a granulating device. The corrosion inhibition material is a biodegradable material. Since the prepared mildew inhibitor and antibacterial agent needs to be placed in a plate, it will be in a humid anaerobic environment. In order to allow the corrosion inhibition material to slowly decompose in a humid anaerobic environment, a biodegradable material is selected as the corrosion inhibition material. The biodegradable material is arranged on the outer surface of the filler microspheres in a coating manner to form mildew inhibitor and antibacterial agent microspheres, so that the biodegradable material protects the mildew inhibitor and antibacterial material so that the mildew inhibitor and antibacterial agent microspheres meet the requirements of use.
[0010] In one or more embodiments of the present invention, the mold inhibitor includes one or more combinations of biphenyl, o-phenylphenol, 2-pyridinethiol-1-zinc oxide, ammonium persulfate, calcium phosphate, zinc ions, silver ions, copper ion compounds, mustard extract, and mugwort. This allows the mold inhibitor to be selected based on the characteristics of the wood board, the environment in which the wood board is installed, and the type of mold.
[0011] In one or more embodiments of the present invention, the antibacterial agent includes one or more of acetic acid, citric acid, sodium sulfite, sodium bisulfite, benzoic acid, p-hydroxybenzoic acid, lactic acid, and oxalic acid. This allows the use of the antibacterial agent to be selected based on the characteristics of the wood board, the environment in which the wood board is installed, and the type of mold.
[0012] In one or more embodiments of the present invention, the additives include deionized water, a crosslinking agent, a softener, a pH adjuster, ethanol, and a curing agent. During the preparation of the mildew and antibacterial agent, the mildew and antibacterial agent must be completely mixed together. Therefore, the additives can be used to maximize the mildew and antibacterial properties of the mildew and antibacterial agent while also enabling the preparation of filler microspheres.
[0013] In one or more embodiments of the present invention, the biodegradable material is a biodegradable plastic. In order to meet the characteristic of slow decomposition in a moist anaerobic environment, the biodegradable material is selected from biodegradable plastic. The biodegradable plastic includes one or more combinations of polylactic acid, polyhydroxybutyrate and polyvinyl alcohol. The selected biodegradable plastic has the characteristics of excellent performance and low cost. The number of layers of the biodegradable plastic arranged on the outer surface of the filler microspheres is one or more. Since different layers of biodegradable plastics require different times to decompose, different layers of biodegradable plastics are arranged on the outer layer of the filler microspheres. This can make the prepared anti-mildew and antibacterial agent microspheres decompose in different time periods. Therefore, by arranging anti-mildew and antibacterial agent microspheres with different decomposition periods in the wood board, the anti-corrosion time of the board can be greatly increased.
[0014] In one or more embodiments of the present invention, the number of filler microspheres in the biodegradable plastic is one or more, so that after the biodegradable plastic decomposes, multiple anti-mildew and antibacterial agent microspheres can be released, thereby better protecting the board from corrosion.
[0015] In one or more embodiments of the present invention, the particle size of the filler microspheres is set to 50 to 100 microns, and the particle size of the anti-mildew and antibacterial agent microspheres is set to 100 to 500 microns. This makes the particle size of the prepared anti-mildew and antibacterial agent microspheres extremely small, thereby facilitating the uniform distribution of the anti-mildew and antibacterial agent particles inside the wood board, so that the placement of the anti-mildew and antibacterial agent particles will not affect the structure of the wood board, while increasing the placement density within the board. At the same time, in order to ensure that the placement of the anti-mildew and antibacterial agent particles has the longest possible anti-corrosion period for the wood board, it is necessary to evenly arrange the anti-mildew and antibacterial agent particles of different biodegradable plastic layers in sequence, so that the anti-mildew and antibacterial agent particles of different biodegradable plastic layers decompose in different cycles, so that the active anti-mildew and antibacterial agent continues to exist in the wood board for anti-corrosion, avoiding the board from getting moldy due to moisture during use.
[0016] The preparation equipment of the non-toxic ecological mildew and antibacterial agent comprises:
[0017] Magnetic stirrer, the magnetic stirrer is selected to have stirring and heating functions, so that the raw materials can be heated as needed while the raw materials are heated. The magnetic stirrer is used to independently mix the antifungal raw materials and the antibacterial raw materials, so that the antifungal raw materials are mixed separately, and the antibacterial raw materials are mixed separately and evenly, so that the mixed antifungal raw materials and antibacterial raw materials can be prepared subsequently. The magnetic stirring device is also used to melt and emulsify the biodegradable plastic raw materials. Since the biodegradable plastic needs to be coated on the surface of the filler microspheres, the biodegradable plastic needs to be melted and emulsified so that the biodegradable plastic in the emulsified state is convenient for subsequent preparation. At the same time, it is necessary to control the temperature when the biodegradable plastic is melted so that the temperature during melting does not destroy the properties of the biodegradable plastic, so that the emulsified biodegradable plastic can be decomposed in a humid, oxygen-free environment. The magnetic stirring device is also used to mix the antifungal raw materials, antibacterial raw materials and additive raw materials together, so that the raw materials for preparing the antifungal and antibacterial materials are mixed together.
[0018] A ball mill is used to grind solid raw materials so that the solid raw materials can be prepared and easily mixed with other raw materials, thereby making the raw materials in the prepared product evenly mixed.
[0019] Spray drying granulator, the spray drying machine can prepare the raw materials into microsphere particles by spray drying according to the needs of use. The spray drying granulator is used to prepare the mixed antifungal raw materials, antibacterial raw materials and additive raw materials into filler microspheres, so that the mixed antifungal raw materials, antibacterial raw materials and additive raw materials can be quickly prepared into filler microspheres in the spray dryer. The temperature needs to be strictly controlled during preparation to ensure that the granulation process does not destroy the activity of the raw materials. The spray drying granulator is also used to wrap the emulsified biodegradable plastic on the outside of the filler microspheres to prepare antifungal and antibacterial agent microspheres. The emulsified biodegradable plastic needs to be wrapped on the surface of the antifungal and antibacterial microspheres, so that the preparation of the required antifungal and antibacterial agent microspheres can be completed.
[0020] A method for preparing a non-toxic ecological mildew and bacteriostatic agent, the preparation method comprising:
[0021] S1. Prepare the raw materials of mildew inhibitors, antibacterial agents, additives and biodegradable plastics separately and set them aside for future use; select the raw materials for preparing mildew inhibitors, antibacterial agents and additives according to the mildew inhibitors and antibacterial agents required for the preservation of wood boards, and select the required biodegradable plastics according to the effective period of mildew inhibitors and antibacterial agents in wood boards, so that when the mildew inhibitors and antibacterial agents initially sprayed in the wood boards are inactivated, the biodegradable plastics can be decomposed, thereby releasing the mildew inhibitors and antibacterial agents wrapped therein.
[0022] S2. The solid raw materials corresponding to the mildew inhibitor, bacteriostatic agent, additive and biodegradable plastic are classified and ground in a ball mill; the mildew inhibitor, bacteriostatic agent and additive solid raw materials can be ground separately, or the mildew inhibitor, bacteriostatic agent and additive solid raw materials can be mixed together for grinding, so that the solid raw materials for preparing mildew inhibitor and bacteriostatic material can be mixed in advance, which also shortens the time for grinding the raw materials and improves the efficiency of preparing mildew inhibitor and bacteriostatic agent.
[0023] S3, respectively placing the mold inhibitor raw material and the bacteriostatic raw material into a magnetic stirrer and stirring and mixing to obtain a mixture, then adding the additive to the mixture, stirring and mixing to obtain a mixed solution 1, and emulsifying the mixed solution 1 to obtain a mixed solution 2;
[0024] S4, putting the mixed solution 2 into a spray drying granulator, and preparing filler microspheres by the spray drying granulator for future use;
[0025] S5, placing the biodegradable plastic raw material into a magnetic stirrer, melting it at high temperature, and then emulsifying it to obtain a third mixed solution;
[0026] S6. The filler microspheres and mixed solution three are mixed and placed into a spray drying granulator. The spray drying granulator produces antifungal and antibacterial agent microspheres 1. The antifungal and antibacterial agent microspheres 1 are placed into a spray drying granulator with mixed solution three and produced into antifungal and antibacterial agent microspheres 2. Antifungal and antibacterial agent microspheres 1 are provided with a layer of biodegradable plastic, and antifungal and antibacterial agent microspheres 2 are provided with two layers of biodegradable plastic. Therefore, when preparing the antifungal and antibacterial agent microspheres, different numbers of layers of biodegradable plastic antifungal and antibacterial agent microspheres can be prepared based on the active period of the antifungal and antibacterial agent in the wood board and the life of the wood board under good antiseptic conditions, so that the antifungal and antibacterial agent will continue to prevent mold on the wood board throughout its life cycle.
[0027] In one or more embodiments of the present invention, the particle size of the solid raw material after grinding by a ball mill is 1 to 2 microns, the rotation speed of the magnetic stirrer when mixing the raw materials is set to 3000 to 5000 r / min, the internal temperature of the magnetic stirrer during emulsification in S3 is set to 60 to 80°C, and the internal temperature of the magnetic stirrer during melting and emulsification in S5 is set to 160 to 200°C.
[0028] Compared with the prior art, the present invention has the following advantages:
[0029] (1) The mildew and antibacterial agent provided by the present invention is composed of an mildew and antibacterial material arranged inside and a corrosion-inhibiting material arranged outside. The internal mildew and antibacterial agent is protected by the external corrosion-inhibiting material, so that the internal mildew and antibacterial agent is in a sealed state before the corrosion-inhibiting material decomposes, and its activity does not change. When the corrosion-inhibiting material decomposes in a moist anaerobic environment, the mildew and antibacterial material can be released, thereby preventing the wooden board from corrosion by the released mildew and antibacterial material, thereby extending the corrosion protection time of the board;
[0030] (2) The present invention arranges different layers of corrosion-inhibiting materials on the outer surface of the filler microspheres, and at the same time, different layers of slow-release materials are sequentially and evenly arranged in the board, and the time for the corrosion-inhibiting materials to decompose matches the time when the mildew-proof and antibacterial materials lose their activity. Therefore, before the mildew-proof and antibacterial materials initially sprayed in the wood board are inactivated, the corrosion-inhibiting materials arranged on the outer side of the mildew-proof and antibacterial agent microspheres will decompose, and the filler microspheres inside will be released into the board, thereby preventing the wooden board from corrosion by the released mildew-proof and antibacterial materials, and effectively extending the anti-corrosion time of the mildew-proof and antibacterial agents on the board;
[0031] (3) The anti-mildew and antibacterial agent provided by the present invention is released by decomposition, ensuring that before the anti-mildew and antibacterial agent used for protection in the wooden board is inactivated, the new anti-mildew and antibacterial material will be released into the board for corrosion protection, which greatly extends the protection time of the anti-mildew and antibacterial agent on the board, cleverly solves the problem of inactivation of the anti-mildew and antibacterial agent when used on wooden boards in a humid environment, can improve people's confidence in the use of wooden boards, and has good promotion value.

[0039] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
[0040] like Figures 1 to 3 As shown, the non-toxic ecological mildew and antibacterial agent in one embodiment of the present invention is used to solve the problem that the non-toxic ecological antiseptic and antibacterial agent cannot be used to prevent corrosion of wooden boards due to the loss of activity.
[0041] like Figures 1 to 3 As shown, the non-toxic ecological anti-mildew and antibacterial agent includes a filler 1 and a protective layer 2. The filler 1 is arranged inside the protective layer 2, so that the protective layer 2 can protect the filler 1, thereby preventing the filler 1 from contacting the outside world, so that the filler 1 can only contact the outside world when the protective layer 2 is destroyed and exposed to the outside. The filler 1 is an anti-mildew and antibacterial material, which is used to prevent the corrosion of wooden boards so that the wooden boards will not breed mold in a humid environment, thereby preventing the wooden boards from being corroded due to mold in a humid environment. The protective layer 2 is a corrosion-inhibiting material, which has the ability to slowly decompose in a humid environment. Therefore, when the corrosion-inhibiting material decomposes after a certain period of time, the internal anti-corrosion and antibacterial material can be released.
[0042] Specifically, when the wooden board is being processed, it will be treated with an anti-corrosion agent, and an anti-mildew and antibacterial agent will be sprayed inside the wooden board to prevent the wooden board from producing mold in a humid environment and causing mold and deterioration. However, the activity period of the anti-corrosion and antibacterial agent is limited. When the anti-corrosion and antibacterial agent is inactivated, the wooden board will no longer have the ability to prevent corrosion in a humid environment. When the wooden board is moldy and deteriorates due to mildew, it is usually necessary to replace the board or re-treatment with an anti-corrosion agent. Therefore, in order to make the anti-corrosion and antibacterial agent in the wooden board active for a long time, an anti-mildew and antibacterial agent prepared from an outer layer of corrosion-inhibiting material and an inner layer of anti-corrosion and antibacterial material is evenly arranged in the wooden board. When in use, the corrosion-inhibiting material will decompose within a certain period, thereby releasing the inner anti-corrosion and antibacterial material, so that new anti-corrosion and antibacterial material is released in the board, so that the board can be anti-corroded by the released anti-corrosion and antibacterial material, thereby extending the anti-corrosion period of the board and extending the service life of the board.
[0043] Furthermore, the corrosion-inhibiting material is arranged on the outer surface of the anti-mildew and antibacterial material in a wrapped manner to form an anti-mildew and antibacterial agent, so that the corrosion-inhibiting material can well protect the anti-mildew and antibacterial material, ensuring that the anti-mildew and antibacterial material in the corrosion-inhibiting material is stored in a closed environment for a long time, so that the activity of the anti-mildew and antibacterial material will not be affected during storage. Under the action of the corrosion-inhibiting material, the anti-mildew and antibacterial material can be released within the inactivation period of the anti-corrosion material sprayed in the wood board in the early stage, thereby extending the protection period.
[0044] Furthermore, the mildew-proof and antibacterial material includes mildew-proof agents, antibacterial agents and additives. The mildew-proof agents are used to prevent mildew on wooden boards, the antibacterial agents are used to inhibit the growth of mildew in wooden boards, and the additives are used to prepare mildew-proof and antibacterial agents.
[0045] Preferably, the weight ratio of the mildew inhibitor, the antibacterial agent and the additive is 10-15:2-2.5:5.5-6.5. The mildew inhibitor, the antibacterial agent and the additive are mixed evenly and prepared into filler microspheres. In order to make the prepared mildew inhibitor and antibacterial agent material more effective, the mildew inhibitor, the antibacterial agent and the additive need to be fully stirred evenly by a stirring device during preparation, and then prepared into filler microspheres by a granulating device. The corrosion inhibition material is a biodegradable material. Since the prepared mildew inhibitor and antibacterial agent needs to be placed in the plate, it will be in a humid anaerobic environment. In order to allow the corrosion inhibition material to slowly decompose in a humid anaerobic environment, the corrosion inhibition material is selected from biodegradable materials. The biodegradable material is arranged on the outer surface of the filler microspheres in a coated manner to form mildew inhibitor and antibacterial agent microspheres, so that the biodegradable material protects the mildew inhibitor and antibacterial material so that the mildew inhibitor and antibacterial agent microspheres meet the requirements of use.
[0046] Optionally, the mold inhibitor includes one or more of biphenyl, o-phenylphenol, 2-pyridinethiol-1-zinc oxide, ammonium persulfate, calcium phosphate, zinc ions, silver ions, copper ion compounds, mustard extract, and mugwort. This allows the mold inhibitor to be selected based on the characteristics of the wood board, the environment in which the wood board is installed, and the type of mold.
[0047] Optionally, the antibacterial agent includes one or more of acetic acid, citric acid, sodium sulfite, sodium bisulfite, benzoic acid, p-hydroxybenzoic acid, lactic acid, and oxalic acid. This allows the use of the antibacterial agent to be selected based on the characteristics of the wood board, the environment in which the wood board is installed, and the type of mold.
[0048] Specifically, the additives include deionized water, a cross-linking agent, a softener, a pH adjuster, ethanol, and a curing agent. When preparing the anti-mold and anti-bacterial agent, the anti-mold and anti-bacterial agent must be mixed together. Therefore, the additives can be used to maximize the anti-mold and anti-bacterial properties of the anti-mold and anti-bacterial agents while also enabling the preparation of filler microspheres.
[0049] Preferably, the biodegradable material is a biodegradable plastic. In order to meet the characteristic of slow decomposition in a moist anaerobic environment, the biodegradable material is selected from biodegradable plastic. The biodegradable plastic includes one or more combinations of polylactic acid, polyhydroxybutyrate and polyvinyl alcohol. The selected biodegradable plastic has the characteristics of excellent performance and low cost. The number of layers of biodegradable plastic arranged on the outer surface of the filler microspheres is one or more. Since different layers of biodegradable plastic require different times to decompose, different layers of biodegradable plastic are arranged on the outer layer of the filler microspheres. This can make the prepared anti-mildew and antibacterial agent microspheres decompose in different time periods. Therefore, by arranging anti-mildew and antibacterial agent microspheres with different decomposition periods in the wood board, the anti-corrosion time of the board can be greatly increased.
[0050] Preferably, the number of the filler microspheres in the biodegradable plastic is one or more, so that after the biodegradable plastic is decomposed, a plurality of anti-mildew and antibacterial agent microspheres can be released, thereby better preventing the board from corrosion.
[0051] Preferably, the particle size of the filler microspheres is set to 50 to 100 microns, and the particle size of the anti-mildew and antibacterial agent microspheres is set to 100 to 500 microns. This makes the particle size of the prepared anti-mildew and antibacterial agent microspheres extremely small, making it easier to evenly distribute the anti-mildew and antibacterial agent particles inside the wood board, so that the placement of the anti-mildew and antibacterial agent particles will not affect the structure of the wood board, while increasing the placement density within the board. At the same time, in order to ensure that the placement of the anti-mildew and antibacterial agent particles has the longest possible anti-corrosion period for the wood board, it is necessary to evenly arrange the anti-mildew and antibacterial agent particles of different biodegradable plastic layers in sequence, so that the anti-mildew and antibacterial agent particles of different biodegradable plastic layers decompose in different cycles, so that the active anti-mildew and antibacterial agent continues to exist in the wood board for anti-corrosion, avoiding the board from getting moldy due to moisture during use.
[0052] During use, in order to prolong the anti-corrosion time of the non-toxic ecological mildew and antibacterial agent on the wood board, different layers of biodegradable plastic mildew and antibacterial agent microspheres are prepared. Usually, 1 to 3 layers are sufficient. Then, different layers of biodegradable plastic mildew and antibacterial agent microspheres are evenly spaced in the wood board. It should be noted that when the mildew and antibacterial agent microspheres are set in the wood board, the wood board has been sprayed with the mildew and antibacterial agent for the first time. Then, when the wood board is used, before the mildew and antibacterial agent sprayed for the first time is inactivated, a layer of biodegradable plastic mildew and antibacterial agent microspheres is set, and the biodegradable plastic layer will decompose, making the mildew and antibacterial agent inside When the fungal material is released into the board, new anti-mildew and antibacterial material can be formed in the board, so that the new anti-mildew and antibacterial material can preserve the wood board; at this time, the outer side of the anti-mildew and antibacterial agent microspheres with two layers of biodegradable plastic will decompose the remaining biodegradable plastic layer, and before the anti-mildew and antibacterial material released by the former is inactivated, the remaining biodegradable plastic layer will be completely decomposed, and the internal anti-mildew and antibacterial material will be released, so that new anti-mildew and antibacterial material can be formed again in the wood board, and then the new anti-mildew and antibacterial material can preserve the wood board; and so on, the anti-mildew time of the anti-mildew and antibacterial agent on the wood board can be effectively prolonged.
[0053] The preparation equipment of the non-toxic ecological mildew and antibacterial agent in one embodiment of the present invention is used for preparing the non-toxic ecological mildew and antibacterial agent.
[0054] Specifically, the preparation equipment includes a magnetic stirrer. The magnetic stirrer is selected to have stirring and heating functions, so that the raw materials can be heated as needed while the raw materials are heated. The magnetic stirrer is used to independently mix the antifungal raw materials and the antibacterial raw materials, so that the antifungal raw materials are mixed separately and the antibacterial raw materials are mixed separately and evenly, so that the mixed antifungal raw materials and antibacterial raw materials can be used for subsequent preparation. The magnetic stirring device is also used to melt and emulsify the biodegradable plastic raw materials. Since the biodegradable plastic needs to be coated on the surface of the filler microspheres, the biodegradable plastic needs to be melted and emulsified so that the emulsified biodegradable plastic is convenient for subsequent preparation. At the same time, it is necessary to control the temperature of the biodegradable plastic when melting so that the melting temperature does not destroy the properties of the biodegradable plastic, so that the emulsified biodegradable plastic can decompose in a humid, oxygen-free environment. The magnetic stirring device is also used to mix the antifungal raw materials, antibacterial raw materials and additive raw materials together, so that the raw materials for preparing the antifungal and antibacterial materials are mixed together.
[0055] Furthermore, the preparation equipment includes a ball mill, which is used to grind the solid raw materials so that the solid raw materials can be mixed with other raw materials during preparation, thereby making the raw materials in the prepared product evenly mixed.
[0056] Furthermore, the preparation equipment includes a spray drying granulator, which can prepare the raw materials into microsphere particles by spray drying according to the needs of use. The spray drying granulator is used to prepare the mixed antifungal raw materials, antibacterial raw materials and additive raw materials into filler microspheres, so that the mixed antifungal raw materials, antibacterial raw materials and additive raw materials can be quickly prepared into filler microspheres in the spray dryer. The temperature needs to be strictly controlled during preparation to ensure that the granulation process does not destroy the activity of the raw materials. The spray drying granulator is also used to wrap the emulsified biodegradable plastic on the outside of the filler microspheres to prepare antifungal and antibacterial agent microspheres. The emulsified biodegradable plastic needs to be wrapped on the surface of the antifungal and antibacterial microspheres, so that the preparation of the required antifungal and antibacterial agent microspheres can be completed.
[0057] like Figure 4 As shown, the preparation method of the non-toxic ecological mildew and antibacterial agent in one embodiment of the present invention comprises:
[0058] S1. Prepare the raw materials of mildew inhibitors, antibacterial agents, additives and biodegradable plastics separately and set them aside for future use; select the raw materials for preparing mildew inhibitors, antibacterial agents and additives according to the mildew inhibitors and antibacterial agents required for the preservation of wood boards, and select the required biodegradable plastics according to the effective period of mildew inhibitors and antibacterial agents in wood boards, so that when the mildew inhibitors and antibacterial agents initially sprayed in the wood boards are inactivated, the biodegradable plastics can be decomposed, thereby releasing the mildew inhibitors and antibacterial agents wrapped therein.
[0059] S2. The solid raw materials corresponding to the mildew inhibitor, bacteriostatic agent, additive and biodegradable plastic are classified and ground in a ball mill; the mildew inhibitor, bacteriostatic agent and additive solid raw materials can be ground separately, or the mildew inhibitor, bacteriostatic agent and additive solid raw materials can be mixed together for grinding, so that the solid raw materials for preparing mildew inhibitor and bacteriostatic material can be mixed in advance, which also shortens the time for grinding the raw materials and improves the efficiency of preparing mildew inhibitor and bacteriostatic agent.
[0060] S3, respectively placing the mold inhibitor raw material and the bacteriostatic raw material into a magnetic stirrer and stirring and mixing to obtain a mixture, then adding the additive to the mixture, stirring and mixing to obtain a mixed solution 1, and emulsifying the mixed solution 1 to obtain a mixed solution 2;
[0061] S4, putting the mixed solution 2 into a spray drying granulator, and preparing filler microspheres by the spray drying granulator for future use;
[0062] S5, placing the biodegradable plastic raw material into a magnetic stirrer, melting it at high temperature, and then emulsifying it to obtain a third mixed solution;
[0063] S6. The filler microspheres and mixed solution three are mixed and placed into a spray drying granulator. The spray drying granulator produces antifungal and antibacterial agent microspheres 1. The antifungal and antibacterial agent microspheres 1 are placed into a spray drying granulator with mixed solution three and produced into antifungal and antibacterial agent microspheres 2. Antifungal and antibacterial agent microspheres 1 are provided with a layer of biodegradable plastic, and antifungal and antibacterial agent microspheres 2 are provided with two layers of biodegradable plastic.
