以硅溶胶、乙烯基三乙氧基硅烷为主要原料进行反应,然后再添加不同的表面活性剂制备防雾滴涂料,将不同配方的涂料涂覆在普通的聚乙烯(PE)薄膜上,在一定温度下固化后制得防雾薄膜。将所得薄膜进行透光率、接触角、扫描电镜测试。结果表明:喷涂涂料后,薄膜的透光率最好保持在95%以上;接触角明显减少,由原来的85°降低到17°,润湿性和流滴性能良好;经扫描电子显微镜测试表明,制得的防雾滴涂料具有良好的成膜性。
To silica sol, vinyl triethoxysilane as the main raw material for the reaction, and then add a different surfactant to prepare anti-drop coating, coating different formulations of the coating on a common polyethylene (PE) film, in the Antifog film is obtained after curing at a certain temperature. The resulting film was light transmittance, contact angle, scanning electron microscopy. The results show that after the coating is sprayed, the light transmittance of the film is preferably kept above 95%; the contact angle is obviously reduced from 85 ° to 17 °, and the wettability and the dripping performance are good. The results of scanning electron microscopy , Prepared anti-drop coating has good film-forming properties.
