【 中文摘要 】本发明公开了一种沥青路面减霾涂层，其质量份组成为：纳米二氧化钛1份、活性氧化铝1～5份、环氧树脂7～8份、固化剂2～3份、助剂2～4份，所述的固化剂为改性脂肪胺类液体固化剂HTS 4512与特种复合材料环氧固化剂HTC 101的质量比为2～4 : 1的混合物，助剂是消泡剂与金刚砂、炭黑的质量比为1 : 2～4 : 1的混合物。本发明利用活性氧化铝和纳米二氧化钛之间的协同作用，所得减霾涂层不但具有良好的耐水性、抗滑性与环保性，而且能够降解汽车尾气中导致二次颗粒物污染的有害气体并较好的吸附汽车尾气中的PM2.5颗粒物，达到更好的减霾效果，试验表明该涂层对PM2.5的最佳减霾效率可达41.2μg/m³·min。

【 英文摘要 】The invention discloses a haze-reducing coating of a bituminous pavement. The haze-reducing coating comprises the following components in parts by mass : 1 part of nano-titanium dioxide, 1-5 parts of active aluminum oxide, 7-8 parts of epoxy resin, 2-3 parts of a curing agent and 2-4 parts of an assistant, wherein the curing agent is a mixture of a modified fatty amine liquid curing agent HTS-4512 and a special composite epoxy curing agent HTC-101 based on a mass ratio of (2-4) to 1; the assistant is a mixture of a defoamer and carborundum or carbon black based on a mass ratio of (1 to 2) to (4 to 1). According to the haze-reducing coating, the synergistic effect of active aluminum oxide and nano-titanium dioxide is used; the obtained haze-reducing coating not only is good in water resistance, slip resistance and environmental friendliness but also can degrade harmful gas causing secondary particulate pollution in automobile exhaust and well adsorb PM2.5 particles in the automobile exhaust to achieve a relatively good haze-reducing effect; a test shows that the optimal haze-reducing efficiency of the coating on the PM2.5 particles can reach 41.2 microgram/m<3>.min.
