Abstract

The invention discloses an abrasion-resistant and environment-friendly polyurethane sports ground material and a preparation method thereof. The material is blended with an elastomer A component and a B component, wherein the elastomer A component comprises methylene diphenyl diisocyanate and polyether glycol; the B component comprises polyether triols, polyether glycol, a cross-linking agent, a plasticizer, epoxy resin, acrylic acid, silica solution, whiskers, aluminium oxide and pigment. The sports ground material is used to overcome the harm to human bodies and unsafe hidden dangers caused by TD1 and MOCA used in conventional sports ground paving materials, and provides an environment-friendly, abrasion-resistant, low-toxicity, harmless, low-cost and high-properties polyurethane sports ground material.

Description

technical field [0001] The invention relates to the technical field of sports, in particular to a preparation method of a wear-resistant and environment-friendly polyurethane sports field material. Background technique [0002] Since the use of polyurethane track in the 19th Olympic Games held in Mexico in 1968, it has opened up a new situation in the use of polyurethane materials in sports venues, and polyurethane plastic sports venues have gained unprecedented popularity all over the world. With the development of the national fitness campaign in our country, the polyurethane plastic runway is showing a vigorous development trend. [0003] The traditional polyurethane flooring materials are all toluene diisocyanate (TDI) type. Due to the heavy metal substances contained in the TDI polyurethane track, it will oxidize and pollute the environment during use. For example, lead becomes lead oxide after oxidation, which affects human health in the form of dust. Lead mostly acc...
