preparation example 1

[0049] Preparation of modified sulfur powder

[0050] Heat 100g of sulfur with a mass purity of 99% to 120°C, add 3.5g of styrene after melting, and mix for 15 hours. Mesh sieve to obtain modified sulfur powder for future use.

preparation example 2

[0052] Preparation of Nano Zirconium Phosphate Composite

[0053] Add 10ml of tetraethyl titanate to 150ml of absolute ethanol and stir evenly, then add 7ml of phosphoric acid with a mass concentration of 85%, and adjust the pH to 5.5 with ammonia water with a mass concentration of 28%, and then add 0.15 g of silver nitrate, stirred and dissolved to obtain a mixed solution, then 20 ml of deionized water dissolved in 2 g of zirconium carbonate was added dropwise to the mixed solution, and continued to stir in the dark for 10 hours. After the end, the precipitated product was repeatedly washed with deionized water until the washing liquid was neutral, then vacuum-dried for 24 hours, and finally the dried powder material was roasted at 1050°C for 4 hours to obtain a nano-zirconium phosphate composite material with a particle size of 220nm ,spare.

preparation example 3

[0055] Preparation of Adhesion Promoters

[0056] Take by weighing 30g propylene glycol methyl ether acetate, 16g n-butanol and 8g deionized water and place in the reactor, add 20g chlorinated polypropylene resin while stirring until it dissolves completely, then add 33g glycidylamine epoxy resin , after stirring evenly, add 10g of phosphoric acid dropwise, continue stirring for 3 hours, finally add 6g of titanium chelate Dupont Tyzor371 and 500 mesh 4g of borax and continue stirring for 1.5 hours to obtain the required adhesion promoter, set aside.

Abstract

The invention relates to an environment-friendly spraying method for construction by use of coating additives. The coating additives comprise hydroxypropyl methyl cellulose, modified sulfur powder, nanometer zirconium phosphate composite material, electrical nanometer polycrystalline diamond powder, attapulgite, an additive, ethylene glycol monohexyl ether, glycerol and deionized water; the spraying method has unexpected synergism by combination of the coating additives and proper optimization of technological parameters, the prepared coating has excellent wear-resistant, anti-cracking, ultraviolet-prevention and waterproof effects, can be widely applied to spraying of surfaces such as steel sheets for decoration, wood surface, furnish surface and wallpaper surface, fully meets the requirement of persons for diversified functions and has good industrial application prospect and market value.

Description

technical field [0001] The invention relates to an environmental protection construction spraying method, more specifically relates to a novel environmental protection construction spraying method used in conjunction with paint additives, and belongs to the field of functional coating technology. Background technique [0002] With the development of the market economy and the advancement of technological innovation, people are not only satisfied with the humanized and beautiful appearance of commodities and buildings, but also pursue comprehensive and diverse functions, so as to meet people's growing spiritual needs. Coating is a general term for a class of liquid or solid materials that can form a solid coating film with protection, decoration or special properties (such as waterproof, mildew proof, heat preservation, etc.) when applied to the surface of an object. The protection and beautification of objects can be achieved by coating the surface of commodities and buildin...
