Description
Technical Field
The invention relates to the field of coatings, in particular to a water-based plant-based full-matte self-cleaning finishing varnish and a preparation process thereof.
Background
The traditional exterior wall building coating is mainly flat coating emulsion paint before, but the exterior wall flat coating emulsion paint has the outstanding defects, such as: cracking, discoloration, chalking, whiskering, etc.; meanwhile, the modeling is single, the texture is poor, and the like, so the model is gradually eliminated by the market in recent years! Instead of the stone-like paint with better performance and more vivid stone-like effect. The real stone texture paint mainly comprises water-based resin, water-based color paste, natural colored sand and functional additives. Because of the addition of natural colored sand, the surface is not as smooth and dense as flat-coated latex paint. Due to the honeycomb structure on the surface, the pollution problem is easily caused when the honeycomb structure is used on the outer wall, so that the later-stage decoration effect and the maintenance cost are greatly influenced. In order to cope with this problem, however, many coating manufacturers have developed corresponding finishes and processes for their preparation to improve. However, the side light of the bright finishing varnish is high in possibility of blooming, the traditional matte finishing varnish is easy to precipitate after matting, and the problems of poor water resistance and stain resistance of a coating film and the like are caused by incompatibility with a system (the matte powder is oleophilic), insufficient compactness of the coating film and the like, so that the effect is not ideal in the actual application process. Therefore, the development of a water-based finish varnish with a self-cleaning effect, good water resistance, resistance to side light blooming and good stain resistance and a preparation process thereof are urgently needed.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the self-cleaning high-pollution-resistance finish varnish with the self-extinction full-matte effect, the compact hardness of a coating film, the good surface hydrophilicity and the antistatic adsorption and the preparation process thereof are provided.
In order to solve the technical problems, the invention adopts the technical scheme that:
the invention provides a water-based plant-based full-matte self-cleaning finishing varnish, which is prepared from the following components in parts by mass:

20-40 parts of a photocatalyst auxiliary agent;
3-10 parts of a thickening agent;
1-1.5 parts of a pH regulator;
365.5-531 parts of pure water.
Preferably, the plant-based resin is SP2022XP plant-based water-based resin manufactured by DSM corporation.
Preferably, the wetting agent is a winning TEGO4200 wetting agent.
Preferably, the antifreeze agent is ethylene glycol.
Preferably, the coalescent is a decaglycol ester.
Preferably, the nano silica sol JN10-30/1 is produced by Zhejiang Delphin micro-nano science and technology Limited.
Preferably, the photocatalyst auxiliary agent adopts a W920 coating self-cleaning additive produced by New materials GmbH, Shanghai province.
Preferably, the thickener is RM-8W polyurethane thickener produced by Dow chemical.
Preferably, AMP-95 from Angiosu is used as the pH regulator.
The invention also provides a preparation method of the water-based plant-based full-matte self-cleaning finishing varnish, which comprises the following steps:
step 1: weighing 350 parts of 300-fold water in advance and adding the water into a high-speed dispersion machine, regulating the rotation speed of the high-speed dispersion machine to 800-fold water/min at 600-fold, slowly adding 1-2 parts of defoaming agent, 2-4 parts of bactericide, 1-2 parts of wetting agent and 10-15 parts of antifreeze agent in sequence, and dispersing at medium speed for 3-5 min;
step 2: regulating the rotating speed to 800-;
and step 3: regulating the rotating speed to 800-1000 revolutions per minute, sequentially adding 5-10 parts of nano silica sol, 20-40 parts of photocatalyst auxiliary agent, 1-3 parts of thickening agent, 1-1.5 parts of PH regulator and 85.5-221 parts of water, and dispersing at medium speed for 5-10 minutes; thus obtaining the water-based plant-based full-matte self-cleaning finishing varnish.
The invention has the beneficial effects that:
1. full dumb effect promotes anti construction and blooms nature: the water-based resin adopts a local quasi-agglutination phase separation design, forms a concave-convex micro-surface while forming a film, thereby realizing a self-extinction function, and has a full-matte (the gloss at each angle of 20 degrees/60 degrees/85 degrees is within 10 degrees) effect, thereby greatly reducing the problem of side light blooming during construction; meanwhile, compared with the traditional matte powder system, the water resistance, the transparency and the anti-precipitation performance are obviously improved, the generation of water white and fogging problems is reduced, and the essential color of the base material is reduced.
2. Low carbon and environmental protection: the water-based plant-based resin is extracted and synthesized from natural plants, has low dependence on petroleum resources, can reduce carbon emission, and is environment-friendly and low in odor.
3. Weather resistance and color retention are good: the paint is prepared from pure acrylic emulsion with fine particle size, has excellent weather resistance and color retention, and has good matching property with real stone texture paint; the color retention and chalking resistance of the real stone texture paint can be improved, the compact coating and high hardness of the paint can fill up the honeycomb-shaped cavities of the real stone texture paint, and therefore the dust accumulation and precipitation are reduced.
4. Hard and antistatic adsorption of a paint film: the silicate nano-additive is added, the special nano-structure of the silicate nano-additive can reduce the electrostatic adsorption on the surface of the coating film, increase the hardness and compactness of the coating film, and has strong surface hydrophilicity and excellent exterior wall stain resistance.
5. Has a photocatalyst effect: the added anatase type nano titanium dioxide composite sol can absorb ultraviolet rays, decompose organic pollutants, generate hydrophilic groups to facilitate rainwater to wash attached pollutants, and accordingly has a self-cleaning effect.
6. The execution standard is as follows: meets HG/T5065-2016 requirements on finishing varnish for architectural coatings, GB/T31815-2015 requirements on self-cleaning coatings for external surfaces of buildings and HJ 2537-2014 requirements on water-based coatings for environmental marking products
