环氧大豆油丙烯酸酯光固化保护材料的合成

Synthesis of Epoxidized Soybean Oil Acrylate Light Curing Protection Materials

以环氧大豆油和丙烯酸为原料合成环氧大豆油丙烯酸酯(ESOA),对催化剂种类和反应温度进行探讨。以四丁基溴化铵为催化剂、100℃时合成的ESOA预聚体为主体树脂、三羟甲基丙烷三丙烯酸酯(TMPTA)为活性稀释剂、184为光引发剂进行涂膜紫外光固化。结果表明,制得的紫外光固化保护膜材料附着力为1级,硬度为5H,收缩率小且具有良好的柔韧性及耐磨性。

Epoxidized soybean oil acrylate（ESOA）was synthesized from epoxidized soybean oil and acrylic acid.The catalyst type and reaction time were optimized.Then the ESOA film was prepared with the pre-poly-mer synthesized at 100 ℃ with catalysis of tetrabutylammonium bromide as matrix,TMPTA as reactive dilu-ents,184 as light initiator.The results showed that,the film adhesion materials had excellent performance, with level 1 adhesive force,5 H hardness,little shrinkage and good toughness and abrasive resistance.
