Abstract

The invention discloses a water white resistant acrylate emulsion, which is characterized in that the water white resistant acrylate emulsion is prepared from the following raw materials in parts by weight: 20-50 parts of butyl acrylate, 10-30 parts of methyl methacrylate, 1-5 parts of methacrylic acid, 10-30 parts of styrene, 40-60 parts of n-butyl methacrylate, 5-15 parts of cross-linking monomer, 1-5 parts of emulsifier, 5-10 parts of reactive emulsifier, 0.2-0.8 part of initiator, 1-5 parts of a neutralizing reagent and 150-200 parts of deionized water. The water-white-resistant acrylate emulsion disclosed by the invention has excellent water-white resistance.

Description

technical field [0001] The invention belongs to the technical field of polymer emulsion preparation, and in particular relates to a water-resistant white acrylate emulsion and a preparation method thereof. Background technique [0002] Acrylic resin (acrylic resin) is a general term for acrylic acid, methacrylic acid and its derivative polymers. Acrylic resin coatings are thermoplastic or thermosetting resin coatings or acrylic radiation coatings made of (meth)acrylates and styrene as the main body and acrylic resins obtained by copolymerization with other acrylates. [0003] Acrylic resin has the advantages of low price and high cost performance, and has a certain development trend in various industries. For example, thermoplastic acrylic resin does not undergo further crosslinking during the film forming process, so its relative molecular weight is relatively large, it has good gloss and color retention, water resistance and chemical resistance, fast drying, convenient co...
