High-water-white-resistance acrylic acid water-in-water emulsion and preparation method thereof

Abstract

The invention belongs to the technical field of coatings and particularly relates to a high-water-white-resistance acrylic acid water-in-water emulsion and a preparation method thereof. The high-water-white-resistance acrylic acid water-in-water emulsion is prepared from the following substances in parts by weight: 50-80 parts of an acrylate emulsion, 50-70 parts of a silicone acrylate emulsion, 5-12 parts of cellulose, 10-40 parts of an inorganic filler, 5-18 parts of pigments, 5-12 parts of organic silicate ester, 5-12 parts of a silane coupling agent, 1-3 parts of an emulsifying agent, 3-8 parts of an initiator and 50-100 parts of water. By utilizing a reactive emulsifying agent, most emulsifying agent molecules can be bonded to a molecular chain through polymerization reaction, so that a micromolecular existence form of the emulsifying agent is reduced, the desorption, migration and aggregation of the emulsifying agent are avoided, and therefore, the water white resistance of an emulsion coating film is improved.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a highly water-resistant whitening acrylic water-in-water emulsion and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the upsurge of interior decoration has quietly risen, and people have higher and higher requirements for the decorative effect of coatings. With its bold conception, multi-color paint breaks the traditional single-color and flat coating decoration effect, and creates a colorful and three-dimensional decorative surface, which is favored by consumers. At present, the oil-in-water type colorful pattern paint is more popular in the market. Its coating film is plump, bright in color, gorgeous in pattern and perfect in decorative effect. It is actually a colloid, which contains a dispersed phase and a continuous phase. In the dispersed phase, there is The existence of the protective colloid solution makes...

Problems solved by technology

However, the current water-in-water multi-color coatings generally have the problems of poor initial water whitening resistance, particle strength, aging resistance, and corrosion resistance. Every time it rains, after being washed by rain, the surface of the paint film will turn white and turn white. It is not resistant to scratching, loosening or even peeling off, which greatly affects the appearance of the building; at the same time, it also has problems such as poor stability, easy thickening, particle bleeding, etc., and these problems are related to the formulation system of water-in-water multicolor coating The design itself is directly related to
