摘　　要：针对汽车挡风玻璃起雾结霜问题,设计防雾防霜剂产品配方。研究了影响产品防雾、防霜、效果持续时间等特性的因素。结果表明:复合表面活性剂作为防雾组分,能增强挡风玻璃表面亲水特性(水接触角WCA<5°),使表面不起雾;低熔点多元醇作为防霜组分,能使挡风玻璃-18℃不结霜;超低聚合度聚乙烯醇作为成膜剂,能使产品在挡风玻璃表面形成均匀致密的膜,减缓防雾防霜组分的流失,使产品防雾防霜效果持续60 d以上。按照配方制备的防雾防霜剂产品进行了市场化应用。The formulation of anti-fog and anti-frost agent was designed to solve the problem of fog and frost formation in automobile windscreen.The factors affecting the anti-fog,anti-frost,effect duration of the product were studied.The results show that the composite surfactant,as an anti-fog component,can enhance the hydrophilic properties of the windshield surface(water contact Angle WCA<5°)and make the surface fog-free.As an anti-frost component,the low-melting polyol can make the windshield frost-free at-18℃.As a film forming agent,ultra-low polymerization degree PVA can make the product form a uniform and dense film on the surface of the windshield,slow down the loss of anti-fog and anti-frost components,and make the anti-fog and anti-frost effect of the product last for more than 60 days.The anti-fog and anti-frost agent prepared according to the formula has been applied in the market.
