Description

Technical Field

[0001] The present invention relates to the technical field of daily chemical products, and more particularly to a potassium peroxymonosulfate composite salt deodorant granule and a preparation method thereof. Background Art

[0002] Malodor pollution is a nuisance problem closely related to the living environment. Due to the continuous generation of various harmful odoriferous gases and odors in wastewater ponds, sludge, chemical plants, and burnt household appliances, etc., it is unpleasant. At a minimum, it affects people's mood and quality of life, and at worst, it seriously affects people's physical health. Currently, different deodorant products have been developed for different odor gases. For example, for metal smelting waste gases containing nitrogen, sulfur, etc., some oxidant components are used to react with them to make them odorless components, thereby achieving the effect of removing odors. In addition, there are also methods of covering odor gases with aromatic hydrocarbon components to reduce the impact of odors. However, the deodorizing effects of existing deodorant products are not comprehensive enough. Masking deodorants can only cover the odor of gases and cannot fundamentally eliminate them. Therefore, some harmful odors to the body will still be absorbed by the human body, causing harm to the body. Reactive deodorants often require the active ingredients in them to contact the odor to react. Therefore, they often need to be prepared into sprays and sprayed through specific atomization methods to achieve effective deodorization. Therefore, deodorization is relatively complex, and since reactive deodorants are consumables, a large amount of deodorant often needs to be continuously sprayed. Otherwise, as long as new odors are generated, there will be odors. Therefore, it is necessary to develop a deodorant with comprehensive deodorizing effect, long-term effectiveness, and low dosage.

In this application, the specific source of the potassium peroxymonosulfate composite salt is not specifically limited, and various potassium peroxymonosulfate composite salt components well-known to those skilled in the art can be selected, including but not limited to commercially available related composite salt products.

[0025] Among them, the chemical formula of the sodium gluconate is C6H 11 NaO7, CAS-527-07-1.

[0026] In some embodiments, the active oxygen content of the potassium monopersulfate compound salt is not less than 4.5 wt%; in some embodiments, the bulk density of the potassium monopersulfate compound salt is 1.0-1.5 g / c 3 . The LY200 potassium monopersulfate compound salt of Guangdong Leyuan Chemical Materials can be selected, including but not limited to.

[0027] In the present invention, the potassium monopersulfate compound salt is used as the core component, and components such as tricalcium phosphate, potassium pyrosulfate, potassium dihydrogen phosphate, sodium sulfate, sodium hydroxyethanesulfonate, etc. are used as auxiliary components to prepare the deodorant particles. The contents of the components such as tricalcium phosphate, potassium pyrosulfate, potassium dihydrogen phosphate, sodium sulfate, sodium hydroxyethanesulfonate, sodium citrate, sodium carbonate, and sodium gluconate can be determined according to the content of the potassium monopersulfate compound salt. In some embodiments, the raw materials of the potassium monopersulfate compound salt deodorant particles, by weight, include the following components in parts by weight: 12-25 parts of potassium monopersulfate compound salt, 1-5 parts of tricalcium phosphate, 3-8 parts of potassium pyrosulfate, 1-4 parts of potassium dihydrogen phosphate, 1-5 parts of sodium sulfate, 2-5 parts of sodium hydroxyethanesulfonate, 1-3 parts of sodium citrate, 1-3 parts of sodium carbonate, 2-4 parts of sodium gluconate, 4-15 parts of nano-silica, and 1-10 parts of inorganic porous material.

[0028] The nano-silica described in the present invention is a silica component in which at least one dimension is in the nano-size range in three-dimensional space, that is, in the range of 1-1000 nanometers. The inorganic porous material described in the present invention is a component in which an inorganic material is prepared into a component with a large number of pore structures in the microstructure through a specific method.

[0029] In some preferred embodiments of the present invention, the contents of the nano-silica and the inorganic porous material account for at least 8 wt% or more of the total mass of the deodorant granules. The applicant found that adding an appropriate amount of nano-silica and inorganic porous material to the raw materials for preparing the potassium monopersulfate compound salt deodorant particles can greatly improve the adsorption and removal of heavy odors. However, when the contents of the above two components are too small, the improvement of the above adsorption and removal effect is not obvious. After a large number of experiments, it is found that the beneficial effects become significant after the nano-silica and inorganic porous material in the deodorant particles account for at least 8 wt% or more. In a preferred embodiment, the contents of the nano-silica and the inorganic porous material account for 8 wt%-25 wt% of the total mass of the deodorant granules.

[0030] In the present invention, the specific source of the nano-silica component is not particularly limited, and various nano-silica components well-known to those skilled in the art can be selected. In some preferred embodiments, the nano-silica is a mesoporous silica hollow sphere. The mesoporous silica hollow sphere in the present invention is a monodisperse mesoporous silica hollow sphere, which has a highly ordered mesoporous structure, good chemical and thermal stability, and characteristics such as a high specific surface area, a large pore volume, and a hollow structure.

[0031] In some preferred embodiments of the present invention, the particle size of the mesoporous silica hollow sphere is 250 - 450 nanometers; more preferably, its particle size is 350 - 400 nm.

[0032] In some preferred embodiments of the present invention, the pore diameter of the mesoporous silica hollow sphere is not greater than 5 nm; more preferably, its pore diameter is 2 - 3 nm.

[0033] In some preferred embodiments of the present invention, the specific surface area of the mesoporous silica hollow sphere is 300 - 450 m 2 / g; more preferably, its specific surface area is 350 - 420 m 2 / g. The term "specific surface area" in the present invention refers to the total area per unit mass of the material, and can be determined by testing methods well-known to those skilled in the art, such as the BET specific surface area measurement method, etc.

[0034] In the present invention, the specific source of the mesoporous silica hollow sphere meeting the above requirements is not particularly limited, and various mesoporous silica hollow sphere materials well-known to those skilled in the art can be selected, including but not limited to the monodisperse mesoporous silica hollow sphere of Jicang Nano.

[0035] In some preferred embodiments of the present invention, the inorganic porous material is a surface-hydrophilic modified nano-porous carbon powder; the nano-porous carbon powder in the present invention is a nano-carbon powder with a microscopically three-dimensionally interconnected nano-pore structure, where each pore is connected to 12 surrounding pores and the pore structure is ordered.

[0036] In some preferred embodiments of the present invention, the structure of the surface-hydrophilic modified nano-porous carbon powder contains hydroxyl groups; by using the surface-hydrophilic modified nano-porous carbon powder, the deodorant particles can be used in the form of solid particles, or can be prepared into a water dispersant and applied by spraying or other means, improving its adsorption and removal effect on various odors.

[0037] In some preferred embodiments of the present invention, the specific surface area of the surface-hydrophilic modified nano-porous carbon powder is not less than 200 m 2 / g; more preferably, its specific surface area is 200 - 600 2 / g.

[0038] In some preferred embodiments of the present invention, the surface-hydrophilic modified nano-porous carbon powder contains at least two kinds of nano-porous carbon powders with different pore sizes, and the pore size ranges from 8 to 55 nm; the term "pore size" in the present invention refers to the size of the transverse diameter of the porous structure of the nano-carbon powder. Further preferably, the surface-hydrophilic modified nano-porous carbon powder contains large-pore nano-porous carbon powder and small-pore nano-porous carbon powder, wherein the pore size of the large-pore nano-porous carbon powder is not less than 30 nm, and the pore size of the small-pore nano-porous carbon powder is not more than 15 nm; further preferably, the pore size of the large-pore nano-porous carbon powder is 35 to 55 nm, and the pore size of the small-pore nano-porous carbon powder is 8 to 12 nm;

[0039] In some preferred embodiments of the present invention, the mass ratio of the large-pore nano-porous carbon powder to the small-pore nano-porous carbon powder is (1 to 3):1; further preferably, the mass ratio of the large-pore nano-porous carbon powder to the small-pore nano-porous carbon powder is 2.5:1.

[0040] In the present invention, there is no special requirement for the specific source of the surface-hydrophilic modified nano-porous carbon powder that meets the above requirements, and it can be selected from, including but not limited to, the NCP-10 small-pore nano-porous carbon powder and NCP-50 large-pore nano-porous carbon powder of Jicang Nano.

[0041] During the process of completing the present invention, the applicant found that by using nano-silica and surface-hydrophilic modified nano-porous carbon powder, the deodorizing effect of the deodorant particles can be improved to a great extent. Moreover, by coordinating and optimizing the control of parameters such as the particle size, pore size and specific surface area of nano-silica and nano-porous carbon powder, the synergistic effect between components can be significantly improved, and the deodorizing effect of the deodorant particles can be further extended, so that it can still actively adsorb the odor in the environment after spraying, and increase the odor adsorption amount under the same dosage. The applicant speculates that after the nano-silica hollow spheres and nano-porous carbon powder with different pore sizes are mixed with other components in the formula, a large number of micropores with different sizes are formed on the surface and inside of the deodorant particles. These micropores are intricate. Under the interaction of components such as sodium gluconate and sodium hydroxyethyl sulfonate, while improving the interaction between the components of the granule, the surface characteristics of the above micropores are further improved, continuously absorbing the odor in the environment, filling the pore-like structure in the granule with a large amount of odor gas, and at the same time using the intricate micro-porous structure to increase the adsorption amount of the odor gas. When the granule is made into a water dispersant and sprayed, it adsorbs with the odor gas in the environment, and at the same time can still actively adsorb the odor gas in the environment after spraying.

[0042] However, during the process of completing the present invention, the applicant found that when nano-porous carbon powder is used in the deodorant particles, after being made into an aqueous dispersant and sprayed in the environment to be deodorized, the carbon powder in the deodorant particles adheres to the sprayed surface, forming black stains that are not easy to clean, which affects the scope of use and the use environment of the deodorant particles. In some preferred embodiments of the present invention, the potassium peroxymonosulfate composite salt deodorant particles further include a functional composite dispersant component, and the content of the functional composite dispersant accounts for at least 50 wt% or more of the total mass of the nano-silica and the inorganic porous material; further preferably, the functional composite dispersant contains a specially modified polyether-modified trisiloxane and a non-ionic block copolymer; further preferably, the viscosity of the polyether-modified trisiloxane at 25 °C is 10-30 cs; further preferably, the surface tension of the polyether-modified trisiloxane at 25 °C and a concentration of 0.1 wt% (aqueous solution) is not greater than 21 mN / m; further preferably, the mass ratio of the polyether-modified trisiloxane and the non-ionic block copolymer in the functional composite dispersant is the same. The applicant found that by adding the functional composite dispersant component composed of the above two components, the adhesion of the particles to the sprayed surface after spraying can be greatly reduced, so that the deodorant particles can better remove the particles adsorbed with exhaust gas after being deposited after being formulated into an aqueous dispersant and sprayed, and avoid the situation that a large amount of stains remain on the sprayed surface after spraying the deodorant particles of the present application.

[0043] In the present invention, there is no special limitation on the specific sources of the polyether-modified trisiloxane and the non-ionic block copolymer that meet the above requirements, and various components well-known to those skilled in the art can be selected, including but not limited to the GS-2227 polyether-modified trisiloxane silicone wetting agent of GS Chemical and the block-type non-ionic polymer dispersant GS-9277 containing an affinity group.

[0044] Each aspect of the present invention provides a method for preparing the potassium peroxymonosulfate composite salt deodorant particles as described above, which includes the following steps:

[0045] Step 1: Weigh potassium peroxymonosulfate composite salt, tricalcium phosphate, potassium pyrosulfate, potassium dihydrogen phosphate, sodium sulfate, sodium isethionate, sodium citrate, sodium carbonate, sodium gluconate, nano-silica, inorganic porous material and the remaining components according to the ratio respectively;

[0046] Step 2: Dry and grind the potassium peroxymonosulfate composite salt, tricalcium phosphate, potassium pyrosulfate, potassium dihydrogen phosphate, sodium sulfate, sodium isethionate, sodium citrate, sodium carbonate, sodium gluconate, nano-silica, inorganic porous material, add the remaining raw materials and mix them evenly, perform pre-compression degassing on the material, and roll and form to obtain a sheet;

[0047] Step 3: Crush and screen the sheet to obtain the product.

[0161] Step 3: Crush and screen the sheet to obtain the product.

[0162] Performance Test

[0163] Take the same mass of the deodorant particles in the above implementation case and spread them on a surface dish of known mass, and place the surface dish with the deodorant particles in a closed test box at a temperature of 28°C and a relative humidity of 60%. Slowly introduce the experimental odor (including hydrogen sulfide, formaldehyde, methyl sulfide, mercaptan, methylamine, sulfur dioxide, ammonium sulfide, indole) from the top of the test box at a rate of 150ml / min to reach a concentration of 25%. Then, after standing for 3 to 6 hours, take out the weight of the surface dish to measure the weight gain of the surface dish after adsorbing the odor and compare it with the weight of the introduced gas. The weight gain of the surface dish accounts for the proportion of the mass of the introduced gas as the gas removal effect. Prepare 5 groups of surface dishes for the deodorant in each case, and take the average value as the deodorization efficiency result. Record the deodorization effect after 3 hours and 6 hours respectively, and the results are shown in Table 1 below.

[0166] In addition, a PC plate is placed at the bottom of the test box, and then the deodorant particles in the above embodiments are added to water, and after a water dispersion with a concentration of 8% (w / v) is prepared, it is sprayed into the test box from the top of the test box in a spraying manner, so that the deodorant particle water dispersion absorbs the odor in the test box (the odor components and concentrations in the test box are the same as those in the above experiment). After leaving it for 2 hours, the PC plate at the bottom of the test box is taken out, wiped with a paper towel, and the content of residual attachments on the surface of the PC plate after wiping is observed, and the attachments are scored according to the residual situation. If most of the attachments are wiped clean and the residual area of ​​the attachments is less than 10% of the plate, 9 to 10 points are scored; if some of the attachments are wiped clean and the residual area is within 30% of the plate area, 6 to 8 points are scored; if there is obviously a large amount of residue and the residual area is within 50% of the plate area, 3 to 5 points are scored; if the residual area exceeds 50%, 1 to 2 points are scored. Each experimental group conducted 5 experiments and was divided into A~D grades according to the average score, where A grade scores were 8 points or above, B grade scores were between 6.5 and 8 points (excluding 8 points), C grade scores were between 5.5 and 6.5 points (excluding 6.5 points), and D grade scores were between 3 and 5.5 points (excluding 5.5 points). The test results are shown in Table 2 below.

[0169] It can be seen from the above experimental results that the present invention effectively improves the removal effect of the deodorant particles on various odors by regulating the components and proportions of nano-silicon dioxide, inorganic porous materials and functional composite dispersants. At the same time, it can also effectively ensure that when the deodorant particles are made into a dispersion with water and then sprayed, the attached matter can be well removed without causing obvious stains and attached matter residues on the spraying surface.
