Abstract

The invention relates to an environment-friendly material used in sports ground pavement and a preparation method thereof. The material contains the component with the following weight percentage: 15 to 30 percent of diphenylmethane diisocyanate, 15 to 25 percent of polyoxypropylene glycerin ether, 10 to 20 percent of polyoxyethylene propylene glycol ether, 0.4 to 5 percent of trimethylolpropane,2.5 to 5 percent of dried montmorillonite, 2 to 5 percent of epoxide resin, and 20 to 30 percent of dioctylphthalate. The invention changes the prior formula of rubber for used in polyurethane elastic sports ground, and adopts dry nano lamination technology to the mechanical properties of polyurethane elastomer, thus lengthening the service life and reducing the manufacturing cost. More importantly, the invention overcomes the problem of the damage to human bodies and the hidden dangers of TDI and MOCA in the prior art.

Description

technical field [0001] The invention belongs to the field of macromolecule materials, and in particular relates to an environment-friendly sports field pavement material for on-site preparation of polyurethane elastomer and a preparation method thereof. Background technique [0002] Polyurethane elastomers are widely used as paving for sports grounds. At present, most of the materials used to make sports ground pavement are produced by the same or similar TDI-MOCA system as CN1033639A, typically using toluene diisocyanate TDI, polyether diol and organic diluent to make polyurethane prepolymer (commonly known as component A), and then combine component A with chain extender-cross-chain agent polyether polyol\diol butanediol, dibasic ammonia MOCA (3,3'-dichloro-4,4'di Aminodibasic methane) and filler (commonly known as component B) are mixed and then polymerized with a catalyst to make a polyurethane elastomer.
