Problems solved by technology

[0004] In order to solve the problems of two-component matte emulsion and the poor stability of the polymer after adding matting powder, the present invention provides a one-component acrylate matte core-shell emulsion with microphase separation structure, which does not need to add matting powder Powder, without mixing with other polymers, can control the gloss of the film after film formation. In practical industrial applications, the cost is low, the formation stability and storage stability are high, and it has broad application prospects.

Abstract

The invention relates to the technical field of organic macromolecular polymerization, aims to solve the problems that operation is difficult, storage is unstable, and the water resistance is poor due to the fact that overcoat varnish for conventional architectural coatings is subjected to extinction often by adding fumed silica or wax emulsion, and provides one-component acrylic ester matte core-shell emulsions with good anti-water-white performance and a preparation method and application thereof. The raw material components of the emulsions comprise alkyl methacrylate, alkyl acrylate, vinyl monomers without -COOH groups, vinyl monomers containing -COOH groups, organosilicone monomers, crosslinking monomers, a pH modifier, an emulsifier, an initiating agent and deionized water. The one-component acrylic ester matte core-shell emulsions are characterized in that after forming into films, the emulsions have a coarse structure with separated surface micro-phases through a core layer part along with the difference of the neutralization degree of the gadoleic acid functional monomer of 3-10 carbon atoms, and the emulsions with the different matte degrees are obtained. Water-based overcoat varnish prepared through the one-component acrylic ester emulsions has the advantages of good water-white resistance, storage stability, good weather resistance, low cost and the like.

Description

technical field [0001] The invention relates to the technical field of organic polymer polymerization, in particular to a one-component acrylate matte core-shell emulsion with excellent water whitening resistance and its preparation method and application. Background technique [0002] With the improvement of national living standards, there is a higher demand for architectural coatings, and exterior wall coatings have always been the focus of attention in the industry. The current exterior wall coatings are ordinary flat paint, brushed paint, and exterior wall elastic paint. , real stone paint and colorful paint. In recent years, because the decorative effect of real stone paint and granite is similar to marble and granite, it has natural and real natural color, which gives people an elegant, harmonious and solemn aesthetic feeling, and its cost is lower than that of marble, and there is no danger of falling off similar to marble; Colorful paint is a kind of colorful paint...
