Description

A powder treatment agent, an environmentally friendly ceramic tile adhesive and its preparation method Technical Field

[0001] This invention relates to the field of ceramic tile adhesive technology, specifically to a powder treatment agent, an environmentally friendly ceramic tile adhesive, and a method for preparing the same. Background Technology

[0002] Tile adhesive is a modern decoration material used to bond decorative materials such as ceramic tiles, facing bricks, and floor tiles. Tile adhesive has the characteristics of strong adhesion, material saving, safety and firmness, and can effectively prevent tiles from becoming hollow or falling off. It can replace traditional cement mortar.

[0003] The formulation of tile adhesive materials typically includes aggregates (such as quartz sand, heavy calcium carbonate, and fly ash), inorganic cementitious materials (such as cement, gypsum, and lime), and additives (such as adhesive powder, cellulose ether, and water-reducing agents). During preparation, the aggregates, inorganic cementitious materials, and additives are physically mixed in a certain proportion to obtain powdered tile adhesive materials. When used later, water is added and the mixture is stirred before use.

[0004] Currently, the following problems commonly exist in the use of tile adhesives: (1) Since tile adhesives are granular or powdery, a large amount of dust is generated during mixing and use, which has a serious impact on human health; (2) Some raw materials in tile adhesives (such as adhesive powder or emulsion) emit unpleasant chemical odors, causing the tile adhesives to emit unpleasant and irritating chemical odors during water mixing and subsequent construction. Therefore, it is necessary to develop a powder treatment agent for tile adhesives to reduce dust and remove chemical odors during the construction and use of tile adhesives, making the construction process of tile adhesives more green and environmentally friendly. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a powder treatment agent for use in tile adhesive materials, which can reduce dust during the construction and use of tile adhesive materials and remove the chemical odor of tile adhesive materials, making the construction process of tile adhesive materials more green and environmentally friendly, and solving the problem that current tile adhesive materials generate a lot of dust and emit unpleasant chemical odors during construction and use.

[0006] Another objective of this invention is to provide a method for preparing a powder treatment agent, which is simple to prepare and suitable for industrial production.

[0007] Another objective of this invention is to provide a method for preparing an environmentally friendly tile adhesive material. Using the aforementioned powder treatment agent, an environmentally friendly tile adhesive material with low or no dust and low chemical odor can be obtained during construction, making the construction process of the tile adhesive material more green and environmentally friendly.

[0008] Another objective of this invention is to provide an environmentally friendly ceramic tile adhesive material prepared by the above-described preparation method, which generates less dust during mixing, use, and construction, and has a low or no odor.

[0009] To achieve this objective, the present invention adopts the following technical solution:

[0010] A powder treatment agent comprises the following raw materials in parts by weight: 90-110 parts of dust-proof oil, 5-15 parts of slow-release deodorizing material, 2-8 parts of odor-neutralizing material, 2-5 parts of nano whiskers, 1-5 parts of starch ether, and 0.1-0.5 parts of silane coupling agent.

[0014] Preferably, the slow-release deodorizing material includes a slow-release carrier and a deodorizing component;

[0015] The deodorizing components include any one or more combinations of zinc ricinoleate, deodorant BYK, deodorant Y104W, and deodorant 855;

[0016] The slow-release carrier includes any one or more combinations of zeolite, diatomite, and activated carbon.

[0017] Preferably, the particle size of the sustained-release carrier is 200-300 mesh.

[0018] Preferably, the nanocrystals are silicon dioxide nanocrystals, and the diameter of the nanocrystals is 80-120 nm and the length is 0.5-4 μm.

[0019] Preferably, the starch ether comprises any one or a combination of hydroxypropyl starch ether, hydroxyethyl starch ether, and cationic starch ether;

[0020] The silane coupling agent includes any one or more combinations of KH550, KH560, KH570 and KH590.

[0021] A method for preparing a powder treatment agent, comprising the following steps:

[0022] (1) Prepare a saturated solution of the deodorizing component, pour the saturated solution into the slow-release carrier to submerge the slow-release carrier, and perform low-temperature heating and stirring until the saturated solution disappears to obtain a slow-release deodorizing material; wherein, the heating temperature of the low-temperature heating step is 30-40°C, and the stirring speed is 50-100 rpm.

[0023] (2) Add the slow-release deodorizing material, deodorizing material, nano whiskers, starch ether and silane coupling agent to the dustproof oil according to the ratio, stir and disperse evenly to obtain the powder treatment agent.

[0024] A method for preparing an environmentally friendly tile adhesive material, using the above-mentioned powder treatment agent, includes the following steps: spraying the powder treatment agent onto the surface of the tile adhesive material using a spray gun, so that the tile adhesive material is coated with the powder treatment agent to obtain the environmentally friendly tile adhesive material;

[0025] The spraying time is 5 to 10 minutes, the spraying method is intermittent or continuous spraying, and the spray gun pressure is 1 to 3 MPa.

[0026] An environmentally friendly ceramic tile adhesive material is prepared by the above-mentioned method for preparing environmentally friendly ceramic tile adhesive materials.

[0027] The technical solution provided in this application embodiment may include the following beneficial effects: The powder treatment agent of this technical solution contains 90-110 parts of dust-proof oil. When preparing tile adhesive materials, the powder treatment agent of this solution is used to treat the tile adhesive materials. For example, if the powder treatment agent of this technical solution is sprayed on the surface of the tile adhesive materials, the powder treatment agent can coat the powdery tile adhesive materials, thereby significantly reducing the powder generated during the production and use of the tile adhesive materials and achieving a dust-free effect. At the same time, since the powder treatment agent formula of this technical solution contains 5-15 parts of slow-release deodorizing material and 2-8 parts of odor-neutralizing material, through the synergistic effect of the slow-release deodorizing material and the odor-neutralizing material, the odor of the tile adhesive materials can be effectively reduced or removed, so that the tile adhesive materials are low-odor or odorless in the subsequent construction and use process, thereby ensuring that the construction process of the tile adhesive materials is more green and environmentally friendly, and solving the problem that the current tile adhesive materials generate a lot of dust and emit unpleasant chemical odors during construction and use. Detailed Implementation

[0028] To facilitate understanding of the present invention, a more complete description is provided below. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.

[0029] Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in this field or in accordance with the product instructions. Raw materials whose manufacturers are not specified are all conventional products that can be obtained commercially.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] The technical solution of the present invention will be further described below with reference to specific embodiments.

[0032] A powder treatment agent comprises the following raw materials in parts by weight: 90-110 parts of dust-proof oil, 5-15 parts of slow-release deodorizing material, 2-8 parts of odor-neutralizing material, 2-5 parts of nano whiskers, 1-5 parts of starch ether, and 0.1-0.5 parts of silane coupling agent.

[0033] It is worth noting that, because the powder treatment agent of this technical solution contains 90-110 parts of dust-proof oil, when preparing tile adhesive materials, the powder treatment agent of this solution is used to treat the tile adhesive materials. For example, if the powder treatment agent of this technical solution is sprayed onto the surface of the tile adhesive materials, the powder treatment agent can coat the powdery tile adhesive materials, thereby significantly reducing the powder generated during the production and use of tile adhesive materials and achieving a dust-free effect. At the same time, because the powder treatment agent of this technical solution contains 5-15 parts of slow-release deodorizing material and 2-8 parts of odor-neutralizing material, through the synergistic effect of the slow-release deodorizing material and the odor-neutralizing material, the odor of the tile adhesive materials can be effectively reduced or removed, making the tile adhesive materials low-odor or odorless during subsequent construction and use. This ensures that the construction process of tile adhesive materials is more green and environmentally friendly, solving the problem that current tile adhesive materials generate a lot of dust and emit unpleasant chemical odors during construction and use.

[0034] Specifically, after the tile adhesive is treated with the powder treatment agent of this solution, the odor-neutralizing material in the powder treatment agent can first remove most of the chemical odor and other odors emitted by the tile adhesive. When the tile adhesive is mixed with water or emulsion, in addition to the odor-neutralizing material playing an odor-removing role, the slow-release odor-removing material will also continue to slowly play an odor-removing role, ensuring that the tile adhesive has low or no odor during subsequent construction and use.

[0035] Further explanation: The powder treatment agent of this technical solution also contains 2-5 parts of nano-whiskers and 1-5 parts of starch ether. After treating the tile adhesive material with the powder treatment agent of this technical solution, a uniform outer shell containing starch ether and nano-whiskers can be formed on the surface of the tile adhesive material particles. Due to the starch ether and nano-whiskers contained in the outer shell, the tile adhesive material has excellent anti-slip effect. After bonding tiles with this tile adhesive material, it can effectively prevent slippage, with a slippage value ≤0.4mm. If starch ether and nano-whiskers are not added to the powder treatment agent, the anti-slip performance of the treated tile adhesive material will be significantly reduced, with a slippage value reaching 0.5mm.

[0036] Specifically, adding 90-110 parts of dust-proof oil to the powder treatment agent formulation system of this technical solution can fully coat the tile adhesive material, achieving a dust reduction effect and avoiding insufficient coating. Adding 2-5 parts of nano-whiskers and 1-5 parts of starch ether can effectively improve the anti-slip and crack-resistant properties of the tile adhesive material. If the amount of nano-whiskers and starch ether added is too small, there will be no obvious anti-slip effect, while too much starch ether will make the powder treatment agent too thick and viscous, making it difficult to spray. Adding 5-15 parts of slow-release deodorizing material and 2-8 parts of odor-neutralizing material to the formulation system can achieve a good deodorization effect and avoid poor deodorization.

[0037] Further explanation: the dust-proof oil includes any one or more combinations of paraffin oil, white oil, methyl silicone oil, and glycerin;

[0038] The viscosity of the dustproof oil is 100-600 cs.

[0039] It is worth noting that dust-proof oil composed of any one or more of paraffin oil, white oil (industrial grade), methyl silicone oil, and glycerin can effectively coat the tile adhesive material. Its coating effect is good and can significantly reduce the dust generated during the production and use of the tile adhesive material, thereby reducing the harm to the human body. Moreover, this technical solution can further reduce dust and achieve a dust-free effect by using dust-proof oil of a specific viscosity.

[0040] Preferably, the viscosity of the dust-proofing oil in this application is 100-600 cs. The viscosity of the dust-proofing oil reflects the intermolecular interaction between the dust-proofing oil and the powder. The viscosity directly affects the coating effect of the dust-proofing oil. By using a dust-proofing oil with a viscosity of 100-600 cs, the coating effect on the powder is better, and the dust generated during production and use can be significantly reduced. If the viscosity of the dust-proofing oil is too high, it is not conducive to spraying, and it is difficult to evenly spray the powder treatment agent on the surface of the tile adhesive, which will lead to a poor coating effect and require a higher treatment temperature to achieve a better coating effect. If the viscosity of the dust-proofing oil is too low, an oily coating film cannot be formed on the surface of the powder particles, which will also lead to poor dust reduction effect.

[0041] Specifically, the dust-proof oil of this technical solution includes any one or more combinations of paraffin oil, white oil, methyl silicone oil and glycerol. The selected components can be mixed in any proportion to obtain the dust-proof oil.

[0042] Further explanation: the odor-neutralizing material includes any one or more combinations of zinc ricinoleate, deodorant BYK, deodorant Y104W, and deodorant 855.

[0043] The odor-neutralizing material in this technical solution can be any material with deodorizing and odor-neutralizing properties. Preferred odor-neutralizing materials include any one or more combinations of zinc ricinoleate, deodorant BYK, deodorant Y104W, and deodorant MOC00-855, all of which can achieve good deodorizing and odor-neutralizing effects. When using a combination of multiple deodorants, the components can be mixed in any proportion.

[0044] Specifically, zinc ricinoleate is a metallic soap, also known as zinc ricinoleate. It is a safe deodorant containing 6.4%–8.2% zinc. Because it contains active zinc atoms, these atoms can form strong bonds with nitrogen and sulfur atoms in odors, thus thoroughly eliminating odors and achieving a deodorizing effect. The zinc ricinoleate in this technical solution can be in liquid or granular form.

[0045] The deodorant BYK, also known in the industry as German BYK deodorant, can greatly reduce or eliminate the chemical odor emitted by tile adhesives during mixing and use. As a preferred embodiment of the present invention, the deodorant BYK model BYK-P4200 is selected.

[0046] Deodorizer Y104W can effectively remove odors from tile adhesive materials. Specifically, deodorizer Y104W refers to the deodorizer branded by BIORICH in Germany and model number Y104W.

[0047] In this technical solution, deodorant 855 refers to the deodorant brand MOC00 from the United States, model number 855. Deodorant 855 can fully oxidize, complex, and adsorb substances with malodorous odors such as sulfides, thiophenes, naphthiophenes, and naphthenic acids. When used in this technical solution, it can significantly remove malodorous odors from tile adhesive materials and has excellent compatibility, allowing it to be blended with other raw materials in the material.

[0048] Further explanation: the slow-release deodorizing material includes a slow-release carrier and deodorizing components;

[0049] The deodorizing components include any one or more combinations of zinc ricinoleate, deodorant BYK, deodorant Y104W, and deodorant 855;

[0050] The slow-release carrier includes any one or more combinations of zeolite, diatomite, and activated carbon.

[0051] It is worth noting that the slow-release deodorizing material of this technical solution includes a slow-release carrier and a deodorizing component. By loading the deodorizing component onto the slow-release carrier, the deodorizing component can be released into the environment at a slow or controllable rate, thus having a longer duration of effectiveness and achieving long-term deodorization.

[0052] To further clarify, the particle size of the sustained-release carrier is 200-300 mesh.

[0053] Preferably, the particle size of the slow-release carrier in this technical solution is 200-300 mesh, which is beneficial for uniform mixing in the powder treatment agent, and at the same time, the release rate of the deodorizing component is better, avoiding the deodorizing component being released too quickly or too slowly.

[0054] To further explain, the nanocrystals are silicon dioxide nanocrystals, with a diameter of 80–120 nm and a length of 0.5–4 μm.

[0055] The nanocrystals used in this technical solution are silica nanocrystals with a diameter of 80-120 nm and a length of 0.5-4 μm. They can improve the anti-slip effect of ceramic tile adhesives and enhance the anti-cracking effect. They form a fiber network structure at the micron level to resist the slippage of cement paste.

[0056] Preferably, the silica nanocrystals in this technical solution are Huijing 5000 type whisker silicon with a diameter of 80-120 nm and a length of about 2 μm.

[0057] Further explanation: the starch ether includes any one or more combinations of hydroxypropyl starch ether, hydroxyethyl starch ether, and cationic starch ether;

[0058] The silane coupling agent includes any one or more combinations of KH550, KH560, KH570 and KH590.

[0059] By adding one or more of the starch ethers such as hydroxypropyl starch ether, hydroxyethyl starch ether, and cationic starch ether to the powder treatment agent, the anti-sagging and anti-slip properties of the tile adhesive can be significantly improved, giving the tile adhesive a higher yield value.

[0060] Specifically, the silane coupling agents KH550, KH560, KH570 and KH590 can all be purchased commercially.

[0061] A method for preparing a powder treatment agent, comprising the following steps:

[0062] (1) Prepare a saturated solution of the deodorizing component, pour the saturated solution into the slow-release carrier to submerge the slow-release carrier, so as to adsorb the deodorizing component to the maximum extent, and perform low-temperature heating and stirring until the saturated solution disappears to obtain a slow-release deodorizing material; wherein, the heating temperature of the low-temperature heating step is 30-40°C, and the stirring speed is 50-100 rpm.

[0063] (2) Add the slow-release deodorizing material, deodorizing material, nano whiskers, starch ether and silane coupling agent to the dustproof oil according to the ratio, stir and disperse evenly to obtain the powder treatment agent.

[0064] It is worth noting that this technical solution uses a method common in the field to prepare a saturated solution. For example, the solvent (such as water) is first heated to boiling, and the deodorizing component is added to the boiling solvent while stirring until it no longer dissolves (solid particles precipitate). At this point, the solution is cooled to room temperature and the precipitated crystals are filtered out. The solution obtained after filtration is the saturated solution. If the deodorizing component is a liquid, some of the solvent can be evaporated by heating, increasing the concentration of the solute in the solution to reach saturation.

[0065] A method for preparing an environmentally friendly tile adhesive material, using the above-mentioned powder treatment agent, includes the following steps: spraying the powder treatment agent onto the surface of the tile adhesive material using a spray gun, so that the tile adhesive material is coated with the powder treatment agent to obtain the environmentally friendly tile adhesive material;

[0066] The spraying time is 5 to 10 minutes, the spraying method is intermittent or continuous spraying, and the spray gun pressure is 1 to 3 MPa.

[0067] It is worth noting that the tile adhesive material in this technical solution can be any powdered tile adhesive material prepared with any formula in the field. By treating the tile adhesive material with a powder treatment agent, an environmentally friendly tile adhesive material is obtained, which can effectively reduce dust during the later construction and use process, achieving a dust-free effect. Moreover, the added odor-neutralizing material can remove the odor from the tile adhesive material first. When the environmentally friendly tile adhesive material is mixed with water or emulsion, in addition to the odor-neutralizing material playing a deodorizing role, the slow-release deodorizing material will also continue to slowly play a deodorizing role, so that the resulting environmentally friendly tile adhesive material achieves a low-odor or odorless effect during subsequent construction and use.

[0068] It should be noted that the powder treatment agent in this technical solution can be used to treat common powdered tile adhesives on the market to achieve dust removal and odor elimination. In addition, the powder treatment agent in this technical solution can also be used to treat tile back adhesive and other cement powders, such as two-component tile back adhesive, achieving the same dust removal and odor elimination effects.

[0069] Further explanation: In a preferred embodiment of the present invention, the preparation method of the environmentally friendly tile adhesive material includes the following steps: after mixing the raw materials of conventional tile adhesive material in a mixing device, the mixing device continues to mix the materials, and at the same time, a constant pressure spray gun is used to spray the powder treatment agent onto the surface of the rolling tile adhesive material. The spraying time is 5 to 10 minutes, and the spraying method is intermittent spraying or continuous spraying. The spray gun pressure is maintained at 1 to 3 MPa, and the output is adjusted according to the actual situation until the tile adhesive material is coated, thus obtaining the environmentally friendly tile adhesive material.

[0070] Specifically, the pressure of the spray gun is mainly adjusted according to the spraying capacity. If the air pressure is too low, the atomization capacity will be poor, which will cause the dust-proof oil to drip or clump, resulting in uneven coating. If the air pressure is too high, it will blow the powder away, which is not conducive to coating.

[0071] An environmentally friendly ceramic tile adhesive material is prepared by the above-mentioned method for preparing environmentally friendly ceramic tile adhesive materials.

The test results are shown in Table 1 below. Simultaneously, conventional tile adhesive materials that had not undergone powder treatment were mixed with water. The generation of dust during the mixing process and the odor were observed using a smell test. Their anti-slip performance was also tested. The test results are shown in Table 1 below.

[0105] Table 1 Test Results

[0106]

[0107] As can be seen from the test results in Table 1, the environmentally friendly tile adhesives treated with the powder treatment agents of Examples 1, 2, 4, and 5 produced virtually no dust and odor during the water mixing process, making the construction process of the environmentally friendly tile adhesives more green and environmentally friendly. From the results of Example 3, it can be seen that the environmentally friendly tile adhesives treated with the powder treatment agent of Example 3 produced slight dust and emitted a slight odor during the water mixing process. This may be due to the lower amount of dust-proofing oil and odor-neutralizing material added to the powder treatment agent. However, compared to the tile adhesives without powder treatment agent treatment, the dust production and odor emission were significantly reduced. Therefore, using the powder treatment agent of this invention to treat tile adhesives can significantly reduce the powder and odor generated during the production and use of tile adhesives, potentially achieving a dust-free and odor-free effect, making the construction process more green and environmentally friendly.

[0108] According to the slip requirements in the tile adhesive standard JC / T547-2017, the slip dimension of the tile should be ≤0.5mm. As can be seen from the test results in Table 1, the anti-slip performance of the environmentally friendly tile adhesive materials prepared using Examples 1-5 is superior to that of conventional tile adhesive materials. The slip values ​​of the environmentally friendly tile adhesive materials prepared using Examples 1-5 are all lower than those of conventional tile adhesive materials, and the slip values ​​of the environmentally friendly tile adhesive materials prepared using Examples 1, 3, and 4 are even smaller, ≤0.2mm.
