Pavement coating layer and forming method thereof
The invention discloses a pavement coating layer and a forming method thereof. The pavement coating layer comprises a bonding layer and a wear-resistant layer which are arranged from bottom to top; the bonding layer comprises 20-35 parts by weight of epoxy resin and 8-15 parts by weight of a curing agent; the wear-resistant layer comprises the components in parts by weight: 100 to 160 parts of bi-component oily polyurethane, 20 to 35 parts of calcium carbonate, 14 to 25 parts of a corrosion-resistant filler, 0.7 to 1.5 parts of a defoaming agent and 6 to 12 parts of a pigment, wherein the epoxy equivalent of the epoxy resin is 180 to 198 g/mol, and the viscosity of the epoxy resin is 10900 to 15100 mPa*s; the curing agent is a modified aliphatic amine curing agent, the amine value of the curing agent is 280-320 mgKOH/g, and the viscosity of the curing agent is 35-55 mPa*s; the bi-component oily polyurethane comprises a component A containing an isocyanate group and a component B containing a hydroxyl group. The pavement coating layer not only has good weather resistance and abrasion resistance, but also has good bonding performance.
本发明公开了一种路面涂层及其形成方法。该路面涂层包括从下而上设置的粘接层和耐磨层；所述粘接层包括20～35重量份的环氧树脂和8～15重量份的固化剂；所述耐磨层包括100～160重量份的双组分油性聚氨酯，20～35重量份的碳酸钙，14～25重量份的耐腐蚀填料，0.7～1.5重量份的消泡剂，6～12重量份的颜料；其中，所述环氧树脂的环氧当量为180～198g/mol，粘度为10900～15100mPa·s；所述固化剂为改性脂肪胺固化剂，其胺值为280～320mgKOH/g，粘度为35～55mPa·s；其中，所述双组份油性聚氨酯包括含异氰酸酯基团的组分A和含羟基的组分B。该路面涂层不仅具有较好的耐候性能和磨耗性能，而且具有较好的粘接性能。
