以KH-550为打底液对无机型人造石表面进行预处理,然后以紫外光固化涂料罩光。讨论了低聚物和活性稀释单体的组成、消泡剂种类和KH-550的用量对人造石表面紫外光固化涂膜性能的影响。结果表明,以质量分数为3%的KH-550对人造石表面进行预处理后,按低聚物55%,活性稀释单体40%,光引发剂和助剂分别为4%和1%的质量分数配制光固化涂料,当低聚物中环氧丙烯酸酯和聚氨酯丙烯酸酯的质量比为8∶3,活性稀释单体中苯乙烯、1,6–己二醇二丙烯酸酯与三羟甲基丙烷三丙烯酸酯的质量比为1∶2∶1时,所配制的紫外光固化涂料固化后,可在人造石表面获得硬度3H、附着力为1级、光泽度93°且耐酸性好的涂膜,改善了无机型人造石的表面性能。
KH-550 as a primer on the inorganic type artificial stone surface pretreatment, and then UV curing paint cover light. The effects of the composition of oligomers and reactive diluents, the types of defoamers and the amount of KH-550 on the properties of UV cured films on artificial stone surfaces were discussed. The results showed that when the artificial stone surface was pretreated with 3% KH-550, the content of oligomers was 55%, reactive diluent monomer was 40%, photoinitiators and auxiliaries were 4% and 1% respectively Mass fraction of light-cured coating preparation, when the oligomer epoxy acrylate and urethane acrylate mass ratio of 8: 3, reactive diluent monomer styrene, 1,6-hexanediol diacrylate and trimethylol When the mass ratio of the base propane triacrylate is 1: 2: 1, the prepared UV-curable coating can obtain the surface hardness of 3H, adhesion 1, gloss 93 ° and acid resistance Coating, improved surface properties of inorganic type artificial stone.
