防水涂料用醋丙乳液的制备

The Preparation of Vinyl Acetate/Acrylic Emulsion for JS Waterproof Coatings

醋酸乙烯酯-丙烯酸共聚物(醋丙)乳液具有原料价格低廉、环境友好无毒、优异的相容性等优势,但存在耐水耐碱性、稳定性较差等缺点,大大地限制了其在JS防水涂料中的应用。通过调整乳化体系、添加功能单体等方式,制备出适用于防水涂料用的醋丙乳液。

Vinyl acetate/acrylic copolymer emulsion has advantages such as low raw material prices, environmental non-toxicity and excellent compatibility, but its shortcomings such as poor water resistance, alkali resistance and stability greatly limit its application in JS waterproof coatings. By adjusting the emulsification system and adding functional monomers, a vinyl acetate/acrylic emulsion suitable for waterproof coatings is prepared.
