Polyurethane cementing material, polyurethane high-elastic porous mixture as well as preparation method and application of polyurethane cementing material and polyurethane high-elastic porous mixture
The invention discloses a polyurethane cementing material, a polyurethane high-elastic porous mixture as well as a preparation method and application of the polyurethane high-elastic porous mixture, and the polyurethane cementing material comprises the following components in parts by weight: 85-95 parts of polyether polyol, 8-12 parts of 1, 5-pentamethylene diisocyanate, 0.2-0.8 part of an anti-hydrolysis agent and 0.5-1.5 parts of carbon nanotubes. The polyurethane high-elastic porous mixture comprises the following components in percentage by mass: 76.5 to 80 percent of aggregate, 4.5 to 5.5 percent of polyurethane cementing material, 15.5 to 18 percent of rubber particles and 18 to 25 percent of void ratio. The problems that in a current macroporous polyurethane mixture, interface bonding is prone to being eroded by water, the polyurethane mixture is prone to aging and degradation, and skeleton evaluation is lacked in gradation composition design are solved, the interface performance is improved, the raw materials of the polyurethane cementing material, the rubber particles, the gradation composition and the like are optimized, and the interface performance is improved. The overall durability and stability of the polyurethane mixture are greatly improved.
本发明公开了一种聚氨酯胶结料、聚氨酯高弹多孔混合料及其制备方法与应用，聚氨酯胶结料按重量份包括如下组分：聚醚多元醇85～95份、1，5‑五亚甲基二异氰酸酯8～12份、抗水解剂0.2～0.8份、碳纳米管0.5～1.5份。聚氨酯高弹多孔混合料按质量百分比包括如下组分：76.5～80％集料、4.5～5.5％聚氨酯胶结料、15.5～18％橡胶颗粒，空隙率18～25％。本发明克服了当前大孔隙聚氨酯混合料中，界面粘结易受到水分的侵蚀，聚氨酯混合料易老化降解，且级配组成设计中缺乏骨架评价的问题，从界面性能提升出发，通过原材料聚氨酯胶结料、橡胶颗粒及级配组成等方面优化，大大提升了聚氨酯混合料的整体耐久性和稳定性。
