Problems solved by technology

However, when these emulsions are used as film-forming substances, the film-forming time is long, and generally need to be dried naturally for at least 24 hours, so they need to occupy a lot of space; if they are heated and dried, they may foam and cause the surface to bulge and uneven, and the final product obtained poor flexibility

Abstract

The present invention proposes a two-component emulsion and a preparation method thereof, including component A and component B; the preparation method of component A is as follows: adding polyvinyl alcohol and potassium persulfate to water to obtain a first solution, adding potassium persulfate Prepare the second solution in water, then add the second solution, methacrylic acid, and styrene to the first solution for polymerization; add methacrylic acid, methyl methacrylate, isooctyl acrylate, iso Octyl esters, acetoacetoxyethyl methacrylate, ethylene-vinyl acetate copolymer (pre-irradiated with beta radiation before addition) and potassium persulfate, polymerized with stirring at 80‑90 °C; Part B Preparation The method is: mixing zinc acetate, ammonia water, polyvinyl alcohol and water and stirring evenly; the above raw materials are all measured in parts by weight. The two-component emulsion is stored separately and mixed in proportion during use, which can not only take into account the flexibility and strength of film formation, but also help to improve production efficiency.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a two-component emulsion and a preparation method thereof. Background technique [0002] In the preparation of building materials such as real stone paint and soft stone, film-forming emulsions are often used. For example, the Chinese patent application number 200910192563.4 discloses a pure acrylic emulsion of real stone paint, which consists of: nuclear monomer: 5-20% of methyl methacrylate, 5-20% of isooctyl acrylate, 5-10% of butyl acrylate %, high-density cross-linking monomer 1-5%; shell monomer: methyl methacrylate 5-20%, isooctyl acrylate 5-10%, butyl acrylate 5-10%, acrylic acid 1-3%; Polymerizable emulsifier 1-5%; persulfate 1-3%; water 50%. The Chinese patent application number 201510718824.7 discloses a silicon composite water-based acrylic emulsion, including water, butyl acrylate, functional monomers, emulsifiers and initiators. The above components are...
