Abstract

The present invention belongs to the field of polymer material, and is especially sports ground paving material prepared with nanometer montmorillonite and polyurethane and its preparation process. The preparation process includes the following steps: dewatering polyether diol, adding diphenylmethane diisocyanate and further reaction to prepare component A; adding dry nanometer montmorillonite into polyether polyol to modify, adding stuffing and vacuum pumping to prepare component B; mixing component A, component B, black rubber grain and metal carboxylate; and stirring to polymerize, cure and obtain the green sports ground paving material. The green sports ground paving material has high performance and long service life.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and in particular relates to an environment-friendly sports field pavement material prepared by nanometer montmorillonite / polyurethane plastic and a preparation method thereof. Background technique [0002] The polyurethane elastomer of the track and field track of the modern stadium and the paving material of the ball game venue is known to be a polyurethane prepolymer made of toluene diisocyanate TDI, polyether diol and organic diluent, (commonly known as component A ); then component A and the chain extender-cross-chain agent polyether polyol, butanediol of diol, dibasic ammonia MOCA (3,3'-dichloro-4,4'diaminodibasic methane ) and fillers (commonly known as component B) are mixed and then polymerized with a catalyst to make a polyurethane elastomer. So far, the formulas of polyurethane elastomers produced by various manufacturers in my country as sports ground...
