Liquid rubber acrylate as well as preparation method and application thereof

The invention relates to the field of preparation of photosensitive resin oligomer, in particular to liquid rubber acrylate as well as a preparation method and application thereof. The method comprises the following steps: under an ice-water bath condition, carrying out esterification reaction on hydroxyl-terminated liquid rubber and acryloyl chloride in a solvent for 3 hours to obtain liquid rubber acrylate; wherein the hydroxyl-terminated liquid rubber is diene liquid rubber. According to the method provided by the invention, the grafting rate of the hydroxyl-terminated liquid rubber and the yield of the liquid rubber acrylate are improved; meanwhile, the liquid rubber acrylate provided by the invention is used for 3D printing photosensitive resin, so that the flexibility and elasticity of a 3D printing product are effectively improved. 本发明涉及光敏树脂低聚物的制备领域，具体涉及一种液体橡胶丙烯酸酯及其制备方法和应用。该方法包括：在冰水浴条件下，将端羟基液体橡胶和丙烯酰氯在溶剂中进行酯化反应3h，得到液体橡胶丙烯酸酯；其中，所述端羟基液体橡胶为二烯类液体橡胶。本发明提供的方法提高了端羟基液体橡胶的接枝率和液体橡胶丙烯酸酯的产率；同时，将本发明提供的液体橡胶丙烯酸酯用于3D打印
