The wall coating is green and environment-friendly, has the functions of absorbing moisture, guiding moisture, preventing mildew and resisting bacteria, has a certain formaldehyde adsorption function, and has the advantages of no toxicity, no stimulation, high heat resistance, difficult color change, long service life and the like.
Description
Technical Field
The invention relates to the technical field of interior wall decoration materials, in particular to an antibacterial wall coating with a formaldehyde purification function and a preparation method thereof.
Background
The traditional interior wall decoration material contains a large amount of adhesives, and can gradually release formaldehyde to the surrounding environment, and the adhesives not only suffer from the damage of environmental factors such as light, heat, chemical erosion substances and the like in long-time use, but also suffer from the pollution of organisms such as mold and the like, easily cause the color change, the stickiness and the peeling of the interior wall, lose the adhesive force, reduce the mechanical property and cause harm to the environmental sanitation. At present, the antibacterial inner wall latex paint, the antibacterial polyvinyl acetate varnish and other products exist in China, the defects of cracking, wall surface hardening and complex repair exist, and the wall coating has good quality and good ecological performance and shows good development prospect.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides an antibacterial wall coating with a formaldehyde purification function and a preparation method thereof.
In order to achieve the above object, the first aspect of the present invention provides the following technical solutions: an antibacterial wall covering with a formaldehyde purification function comprises, by mass, 35-40 parts of wood fibers; 25-35 parts of cotton fibers; 7-8 parts of silver-zinc-carrying zeolite antibacterial agent; 2-3 parts of sepiolite powder; 2-8 parts of mica; 5-6 parts of a wetting dispersant; 0.5-1 part of organic silicon defoamer; 0.5-1 part of mildew preventive; 10-20 parts of water-soluble sizing material; 20-30 parts of deionized water.
Preferably, the wood fiber and the cotton fiber can be subjected to a package-mixing yarn-making process, the wood fiber is pretreated, the antistatic agent and the deionized water are mixed in proportion and then sprayed on the wood fiber, the wood fiber is balanced for more than 1 day, and then the wood fiber and the cotton fiber are subjected to mixing, feeding and rolling, wherein the cotton fiber plays a skeleton role.
The technical scheme provided by the second aspect of the invention is that the preparation method of the silver-zinc-loaded zeolite antibacterial agent selected for the antibacterial wall coating with the formaldehyde purification function comprises the following steps:
(1) In order to ensure that the silver-loaded antibacterial wall coating has small discoloration degree and better antibacterial property, the silver-loaded antibacterial wall coating is prepared by adding zinc ions for compounding: the composition is 10-15 parts of zeolite powder by mass; 4-5 parts of 0.1mol/L silver nitrate solution; 10-15 parts of 0.1mol/L zinc nitrate solution; 15-20 parts of deionized water;
(2) Mixing 4-5 parts of 0.1mol/L silver nitrate solution and 10-15 parts of 0.1mol/L zinc nitrate solution;
(3) Weighing 10-15 parts of zeolite powder, adding the zeolite powder into the mixed solution, and stirring the mixture to fully react for 3.5-5 hours at the temperature of 45-60 ℃ and the pH value of 6-8;
(4) After full reaction, centrifuging at 400 r/min by using a centrifuge, repeatedly washing the separated solid sample by using deionized water for more than 3 times, and drying by using a dryer;
(5) And heating the dried product in a muffle furnace at the temperature of 400-480 ℃, preserving the heat for more than 1h, and cooling to obtain the silver-loaded zeolite antibacterial agent.
Preferably, the sepiolite powder has a fineness of 280 to 300 meshes.
Preferably, the wetting dispersant is polyethylene glycol wetting dispersant.
Preferably, the mildew preventive is a photocatalyst type nano zinc oxide mildew-proof antibacterial agent.
Preferably, the silicone defoaming agent is polydimethylsiloxane.
Preferably, the water-soluble sizing material is hydroxypropyl ethyl cellulose or polyvinyl alcohol.
The technical scheme provided by the third aspect of the invention is as follows, and the preparation process comprises the following steps:
(1) A pretreatment step: spraying antistatic water, washing and drying the wood fiber and the cotton fiber, uniformly mixing the wood fiber and the cotton fiber in a stirring kettle, feeding, rolling to prepare yarns, and crushing to obtain a fiber raw material;
(2) A material mixing step: mixing sepiolite powder, mica powder and deionized water according to a mass ratio of 1:6:15, preparing a system according to the proportion, and mixing the system with a water-soluble sizing material to prepare an intermediate;
(3) Material forming step: and the intermediate is stirred and dissolved uniformly with the fiber raw material, the silver-zinc-loaded zeolite antibacterial agent, the wetting dispersant, the organic silicon defoamer, the mildew preventive and the deionized water in a blending kettle to obtain a finished wall coat product, the finished wall coat product is fully mixed with a proper amount of warm water before use, stirred uniformly and then kept stand for 1h, and the finished wall coat product is fully stirred again before coating to ensure uniform mixing and no caking.
Compared with the prior art, the invention has the beneficial effects that:
