摘要
研制了一种有机硅改性环氧树脂双组分耐磨涂料,其中A组分由自制的纳米TiO2/微米SiC复合颗粒(TiO2/SiC)、MoS2、γ-缩水甘油醚氧丙基硅烷(KH-560)和有机硅改性环氧树脂组成,固化剂聚酰胺作为B组分。以耐磨失质量比为指标,利用响应曲面法优化了涂料的制备工艺参数,结果表明:涂料优化的工艺参数中填料所占质量比例为70.60%,偶联剂0.80%,MoS21.40%,此时最低磨损失质量比可至0.42%。通过SEM观察涂料磨损形貌并初步探索其磨损机理,研究认为:添加复合粒子的耐磨涂料磨损机理呈粉状磨粒磨损特性。
A 2K silicone modified epoxy resin wear resistant coating was prepared, in which component A was composed of nano - TiO2/μm - SiC, γ - glycidoxypropyltrimethoxy silane （ KH - 560） , molybdenum disulfide （ MoS2 ） and silicone modified epoxy resin, compont B was polyamide curing agent. With the weight loss percentage as criterial, the formula of wear resistant coating was optimized according to the response surface methodology. The results showed that the lowest abrasion weight loss （0. 42% ） could be achieved in a formula 70.60% filler, 0.80% coupling agent, 1.40% MoS2. The morphorlogy of weared surface was observed by SEM, and the wearing mechanism of coatings were discussed preliminarily. It was concluded that the wear behavior of coatings filled with composite particles showed the characteristics of abrasive powder wearing mechanism.
