Abstract

The present invention discloses an environment-protecting type polyurethane paving material for sprorts ground. Said material is formed from component A, B and black rubber granules, which contains no high-toxicity tolylene diisocyanate and contains no heavy metal catalyst.

Description

technical field [0001] The invention relates to an environment-friendly paving material for sports fields, in particular to an environment-friendly paving material for sports fields that does not contain highly toxic toluene diisocyanate and heavy metal catalysts. Background technique [0002] Polyurethane rubber sports field (referred to as plastic sports field) has the advantages of excellent wear resistance, oil resistance, weather aging resistance, suitable elasticity, excellent shock absorption performance, wide hardness range, flatness, non-slip, beautiful color, and is not affected by climate conditions. It is welcomed by the public and is also the development direction of the construction of modern sports venues (polyurethane plastic track, plastic tennis court, plastic basketball court, plastic badminton court, plastic table tennis court, etc.). [0003] But for a long time, it needs to use toluene diisocyanate (TDI, has two kinds of iso...
