Single-component moisture-curable polyurethane plastic track material

Abstract

The invention belongs to the field of sports equipment and particularly relates to a single-component moisture-curable polyurethane plastic track material. The single-component moisture-curable polyurethane plastic track material aims at solving the problems that a traditional double-component polyurethane plastic track material is usually prepared when used, the retention time cannot be too long, meanwhile, much time and labor can be wasted for mixing, metering and matching, raw material waste is caused by probable errors, and therefore the construction cost of a track is increased. The single-component moisture-curable polyurethane plastic track material is prepared from, by mass, 15-30 parts of methylene diphenyl diisocyanate, 1-3 parts of 4, 4'-dicyclohexyl methane diisocyanate, 15-25 parts of polyether polyol, 5-10 parts of hydroxyethyl dodecyl alcohol, 2-4 parts of benzoic acid dibutyl ester, 1-3 parts of dibutyltin dilaurate, 1-2.5 parts of caprolactam, 0.8-1.6 parts of triethanolamine oleate, 1.5-2.8 parts of polyethylene wax, 0.5-1.6 parts of dilauryl thiodipropionate, 1.5-4.5 parts of trimethylolpropane, 10-20 parts of ethyl acetate, 2-4 parts of amino silicon oil, 1-4 parts of filler, 0.5-2.5 parts of antiager and 1.5-3.0 parts of accelerant.

Description

technical field [0001] The invention relates to a polyurethane plastic track material, in particular to a single-component moisture-curing polyurethane plastic track material, which belongs to the field of sports equipment. Background technique [0002] With the development of the national fitness campaign, the requirements for sports settings are also increasing. The plastic track began in the 1960s with the plastic horse racing track laid by the 3M company in the United States with polyurethane materials. Compared with cinder and gravel fields, the plastic runway has the advantages of good elasticity, good shock absorption performance, wear resistance and anti-aging, and does not pollute the environment, and is easy to clean and maintain. Since the 19th Olympic Games, the main track and auxiliary areas of the track and field venues in previous Olympic Games have been paved with plastic, and the plastic track has been internationally recognized as the best competition trac...

Problems solved by technology

[0003] The present invention solves the problem that traditional two-component polyurethane plastic runway materials are generally prepared as they are used, and the storage time will not be too long. At the same time, a lot of time and manpower will be wasted in mixing and measuring ratios, and errors may cause raw materials waste, which increases the construction cost of the runway, and then proposes a one-component moisture-cured polyurethane plastic runway material
