Abstract

The invention discloses a two-component acrylate emulsion with high boiling water resistance and high adhesion and a preparation method thereof, which belongs to the field of architectural coatings and comprises the following raw materials in parts by weight: 40-50 parts of methyl methacrylate, and 15-parts of isooctyl acrylate. 25 parts, 30-40 parts of styrene, 5-10 parts of methacrylic acid, 15-25 parts of butyl acrylate, 10-20 parts of hydroxyethyl acrylate, 2-10 parts of functional monomer, 3-6 parts of emulsifier, 0.1-0.5 parts of persulfate, 0.1-0.5 parts of oxidizing agent, 0.1-0.5 parts of reducing agent, 100-180 parts of water. The two-component acrylate emulsion of the present invention improves the development time when it is matched with the curing agent, and reduces the sensitivity of the paint film to water, thereby effectively improving the peeling, bubbling and Severe whitening, etc.

Description

technical field [0001] The invention relates to a two-component acrylate emulsion with high boiling water resistance and high adhesion and a preparation method thereof, belonging to the field of architectural coatings. Background technique [0002] In recent years, with the continuous improvement of the material level, people's spiritual life has become richer, and the requirements for the home environment have increased significantly. The interior decoration pays attention to environmental protection, health, hygiene, non-toxic and harmless, and water-based coatings just meet this demand. , has a very large market prospect. With my country's accession to the WTO, trade with the world has become more frequent. European and American countries have strict control over the limits of harmful substances in coatings. Foreign countries import a large number of furniture and handicrafts from my country, requiring the content of harmful substances to be strictly controlled within the...
