Problems solved by technology

[0010] Barrier properties: The montmorillonite sheets in the composite material are nano-sized and planar, smaller than the wavelength of visible light, and light waves can bypass the sheets, so the addition of montmorillonite does not affect the transparency of the material, but the general gas Molecules and water molecules cannot pass through the sheets, and must bypass the sheets and diffuse in the gaps between the sheets, which greatly prolongs the route for the gas to pass through

Abstract

The invention relates to a polyurethane elastomer for stadium, which comprises: first constituent and second constituent by weight ratio as 1:2-1:4, and third constituent with percent as said constituents. Wherein, the first constituent is: methyl diphenylene diisocyanate, polyether diatomic alcohol, and montmorillonite; the second constituent is: polyether tribasic alcohol, 3,5-dichloro trifluoro methyl phenyl ethyl ether, chlorcosane, talcum powder, calcium oxide, calcium oxide or lemon yellow-phthalocyanine green mixture, and pentachlorophenol; the third constituent comprises: waste rubber particle and metal catalyst. Compared with prior art, this invention has low cost and good properties.

Description

[technical field] [0001] The invention relates to the technical field of polymer materials, in particular to a polyurethane elastomer used in sports venues and a preparation method thereof. [technical background] [0002] The Minnesota Mining and Manufacturing Company of the United States (namely 3M Company) first laid a 200m long racetrack with polyurethane materials in 1961, and laid a track and field track in 1963. Due to its good use effect, it has attracted the attention of various countries. In 1965, West Germany officially produced plastic track. The Pan American Games held in Canada in 1967 began to use plastic track. At the 19th Olympic Games held in Mexico in 1968, the polyurethane plastic runway was officially adopted, called "Taden" runway, which was recognized by the International Olympic Committee. Since then, the International Olympic Committee has officially designated the plastic runway as one of the necessary conditions for international competitions, and...
