Abstract

An athletic field synthetic surface material relates to the field of plastic materials. The athletic field synthetic surface material is composed of a component A and a component B, wherein, by weight part, the component A is composed of 80-200 parts of vegetable oil polyol at a molecular weight of 2000 and 65-75 parts of MDI (methylene diphenyldiisocyanate), and the component B is composed of 25-35 parts of vegetable oil polyol at a molecular weight of 2000, 30-40 parts of vegetable oil polyol at a molecular weight of 4000, 1-3 parts of MBDA (4, 4'-methylenebis [N-sec-butylaniline], 30-45 parts of fillings, 3-6 parts of pigments, 0.5-1 part of antioxidant, 0.5-1 part of ultraviolet light absorber and 0.1-0.5 part of catalysts. The athletic field synthetic surface material is good in anti-skidding, elastic and shock absorbing performance, capable of reducing fatigue and athletic injury, high in wearing resistance, oil resistance and ageing resistance, excellent in adhesive property, long in service life, free from toxicity and odor, environmentally friendly and free from damage to body health.

Description

technical field [0001] The invention relates to plastic materials, in particular to a synthetic surface layer material for sports grounds. Background technique [0002] Traditional plastic runway products are all TDI (toluene diisocyanate) type. Due to the high vapor pressure of TDI (about 1.33Pa at 20°C), it is seriously irritating to the human respiratory system. In the production of plastic runway slurry and The construction process has caused great harm to human health, and during the use of the plastic runway, harmful gases will be slowly released to affect human health. As early as 1994, IST (International Sports Track Technology Association) put forward the suggestion of "not accepting the use of polyurethane system containing monomeric TDI components for sports track" in response to the problem of "using polyurethane resin to pave sports track", and the vapor pressure of MDI is low (25 ℃ is about 1.33×10-3Pa), which is less harmful to human health, and the plastic r...
