Hydrophobic self-extinction acrylic emulsion and preparation method thereof

The invention discloses a hydrophobic self-extinction acrylic emulsion comprising the following components in parts by weight: 15 to 28 parts of ethyl acrylate, 15 to 35 parts of methyl methacrylate, 7 to 15 parts of styrene, 3 to 5 parts of acrylic acid, the balance being 40 to 60 parts of deionized water, 1.5 to 4 parts of a compound emulsifier, 0.4 to 2 parts of an initiator, 0.5 to 1.5 parts of a pH regulator and 0.3 to 0.5 part of a buffering agent. A shell-core process is adopted, acrylic acid is used as a raw material, acrylic resin is good in film-forming property and large in bonding strength and can be used for preparing the self-matting coating, the functionality of the self-matting coating can be improved, and the self-matting coating prepared from acrylic acid has a matting effect and has hydrophobicity and heat sealing performance. The hydrophobic self-extinction acrylic emulsion can be widely applied to paper packaging products. 本发明公开了一种疏水自消光丙烯酸乳液，按照份数分包括以下成分：丙烯酸乙酯15-28份、甲基丙烯酸甲酯15-35份、苯乙烯7-15份、
