Description

背景技术
底盘装甲”是近几年底盘防锈护理的新项目。虽然叫法不同，但都是在汽车底盘的下面喷涂一层2～4mm毫米厚的弹性密封材料，犹如给车的底盘穿上一层厚厚的铠甲。底盘装甲是对这一技术进行的形象描述。底盘装甲可以有效防护路面砂石对底盘的击打，防止轻微的拖底磨擦；预防酸、碱、盐对底盘铁板的腐蚀；防止底盘螺丝的松脱；降低行驶时噪音的传导，增加驾驶宁静感；阻止底盘铁板热传导，使驾驶室内冬暖夏凉。
溶剂型涂料由于含有大量的有机挥发物，不仅污染环境，危害人体健康，破坏生态环境，而且还造成巨大的资源浪费。随着人们对资源、能源和环境保护的日益关注，要求环保的呼声越来越强烈，国外制定了一系列的严格法规，限制涂料中VOC的排放，因此溶剂型的涂料面临着前所未有的考验，受到水性涂料的严峻挑战，并有被取而代之的趋势。现有涂料中大部分均会使用到丙烯酸乳液作为原料，然后，目前丙烯酸乳液在耐酸、耐碱、耐机油性能不能同时具备。
