摘要
用3-(甲基丙烯酰氧基)丙基三甲氧基硅烷(TMSM)、乙烯基三甲氧基硅烷(VTS)及聚乙烯醇(PVA)对Cu2O颗粒表面有机改性,研究改性剂的种类、用量、搅拌速度及反应时间对改性效果的影响。结果表明:改性剂均提高了Cu2O的亲油性,改性效果排序为TMSM>VTS>PVA;TMSM用量为Cu2O的2mass%时,疏水效果最好,与H2O的接触角为132°;反应过程中搅拌越强烈,改性效果越好;搅拌时间一般控制在60min。以TMSM改性Cu2O为主防污剂的防污涂料,其抗沉降性和分散性能得到改善,涂料附着性能提高,抗冲击性能略下降。
The lipophilicity modification of Cu2O is studied, using organic agents as modifying agent the compatibility and dispersion ability of Cu2O in oleoresin. It was found that the modifying effect is to improve arranged as 3-（trimethoxysilyl） propyl methacriylate（TMSM）, trimethoxy/vinylsilicone（VTS）,polyvinyl alcohol（PVA）in decreasing order. The best weight ratio of TMSM to Cu2O is 1：50. The modifying reaction time is about 60 min and strong stir does good to the modification.The antifouling paints using lipophilicity modified Cu2O as main antifoulant have better subsidence-resistance and attachment ability.
