Sports field poly(ethylene carbonate) polyurethane paving material and preparation method thereof

Abstract

The invention discloses a sports field poly(ethylene carbonate) polyurethane paving material, which consists of a component A, a component B, black rubber particles and a catalyst. The component A comprises the following components in percentage by weight: 20 to 50 percent of diisocyanate, and 50 to 80 percent of poly(ethylene ether carbonate)diol. The component B comprises the following components in percentage by weight: 30 to 50 percent of poly(ethylene ether carbonate), 5 to 25 percent of processing aid, 30 to 70 percent of filler, 0.1 to 2 percent of pigment, 0.01 to 0.1 percent of ultraviolet absorber and 0.01 to 0.1 percent of inhibitor. The weight ratio of the component A to the component B is 1:(1-6), the content of black rubber particles is 10 to 40 percent based on the total weight of the components A and B, and the content of the catalyst is 0.05 to 1 percent based on the total weight of the components A and B. The invention discloses the preparation method of the paving material. The indexes of the paving material reach the performance indexes of polyether polyurethane paving materials. Compared with the polyether polyurethane paving materials, the paving material has higher weather resistance, scrape resistance, wear resistance and caking property, and is lower in cost, nontoxic and environmentally-friendly.
