摘要
采用具有低表面能特性的有机氟单体对苯丙树脂进行改性合成,探讨了氟单体用量及软硬单体比例对树脂性能的影响,用接触角检测仪对涂膜表面与水的接触角进行了测量,并对涂膜的附着力、冲击强度等各项常规性能进行了综合检测,同时进行了实海挂板试验。结果表明,当氟单体含量为17.3%、软硬单体比值为0.46时,树脂性能较好,对应的防污涂料防污性能也最佳。此时涂料涂膜与水的接触角是145.5°,附着力等级1级,在50cm垂直高度下重锤冲击无裂纹。
This research synthetically modified styrene-acrylic resin which adopting organofluorine monomer with the property of 10w surface energy, the influence of ratio of hard and soft monomer, fluorine monomer content on the resin properties was discussed,as well as synthetically testing mostly conventional property of coatings and seawater exposure test has been carried out in the Dalian Bay. When the ratio of soft and hard monomers was 0. 46,17.3G fluorine monomer content, the resin properties were improved by the step-by-step adding method. At the same time, Antifouling performance of the corresponding coating was the best. The result showed that the contact angle between water and coating film was 145.5 ~,adhesion level was 1,and impact strength was much greater than 50kg·cm.
