Problems solved by technology

[0003] Most of the latex paints used in architectural decoration on the market are liquid, with a moisture content of more than 30%, which is easy to deteriorate, and must be added with preservatives, which is poor in environmental protection; moreover, liquid latex paints are not easy to pack, transport and store, store and use liquid latex Paint requires a large number of plastic or iron storage tanks, which are expensive, waste resources, and pollute the environment
In addition, the existing latex paint is completely dependent on resin film formation, the coating has poor hardness, is not resistant to collisions, scratches, and stains

Abstract

The invention relates to an antifouling dry-powdered emulsion paint. Global hardness is provided by the utilization of network-like mineral formed by white cement hydration; an ash-calcium modifying agent is added to improve properties of ash-calcium, and ash-calcium is carbonized to generate netted calcium carbonate which interpenetrates to reinforce middle and late hardness; supported by VAE redispersible latex powder, the system's flexibility and elasticity are improved; by the addition of a composite water reduction material, it is guaranteed that various materials are uniformly dispersed in the system, and micropore structure of the system is improved; by the addition of talcum powder and kaolin, construction performance is improved; by the addition of hydroxyethyl cellulose ether, the system's denseness and water retention capacity are increased; by the introduction of superfine nano-silica, compactness of the system is improved; by the addition of a water repellent, the coating is endowed with overall waterproofing property; and polyaluminum chloride is further added to react with calcium hydroxide in the system so as to generate expansile aluminium hydroxide and hydrated chloroaluminate. Thus, the coating becomes a compact integral body and has strong antifouling performance and good air permeability.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an antifouling dry powder latex paint and a preparation method thereof. Background technique [0002] Latex paint, also known as latex paint, is a kind of organic paint, which is prepared by adding pigments, fillers and various additives with synthetic resin as the base material. According to different production materials, latex paint mainly includes polyvinyl acetate latex paint, ethylene-propylene latex paint, pure acrylic latex paint, styrene-acrylic latex paint and other varieties; according to different product application environments, it is divided into interior wall latex paint and exterior wall latex paint. There are two types of lacquer; according to the gloss effect of decoration, it can be divided into dull, matte, semi-gloss, mercerized and glossy. [0003] Most of the latex paints used in architectural decoration on the market are liquid, with a moist...
