摘要

本章采用乙烯基三甲氧基硅烷与丙烯酸类单体为原料,通过自由基聚合反应合成了有机硅改性丙烯酸树脂,采用红外光谱对获得的树脂进行了结构表征。并将纳米二氧化硅添加到有机硅改性丙烯酸树脂中,喷涂到Q325碳钢表面,通过对静态水接触角和附着力的测定,考察了丙烯酸单体、环氧树脂、纳米二氧化硅的添加量对涂膜性能的影响,并通过正交试验对合成工艺进行了优化。
        The silicone modified acrylic resin was prepared with free radical polymerization reaction using vinyl trimethoxysilane and acrylic monomer as raw materials. The structure of the composite coating was characterized using FI-IR spectrum. Nano SiO_2 particle were added into this silicone modified acrylic resin and then sprayed onto Q235 mild steel surface. The effect of dosage of acrylic acid,nano-SiO_2 particles and epoxy resin on the property of the composite coatings was studied with measuring the static contact angle and adhesion. The optimal technological condition was found out with orthogonal experiments.
