Problems solved by technology

[0004] The problem to be solved by the present invention is to provide a polyurethane composition used in jogging areas of plastic fields and its preparation method. The polyurethane composition is used in jogging areas, which solves the problem of excessive hardness, poor elasticity, and elongation of jogging areas in conventional plastic fields. The problems of low elongation, poor shock absorption and low vertical deformation can better protect the athlete's joints during the warm-up process and help athletes improve their performance

Abstract

The invention relates to a polyurethane composition, in particular to a polyurethane composition for the jogging area of the plastic venue and a preparation method of the polyurethane composition. The polyurethane composition comprises the component A and the component B. The component A comprises 55-75% by mass of castor-oil type polyether polyol, 15-35% by mass of filler, 5-10% by mass of cross-linking agent, 0.5-3% by mass of flame retardant, 0.5-2% by mass of drier, 2-5% by mass of pigment, 0.1-2% of additive and 1-5% by mass of foaming agent. The component B comprises 50-60% by mass of castor-oil type polyether polyol and 40-50% by mass of isocyanate. The polyurethane composition solves the problems of high hardness, poor flexibility, low elongation, poor impact absorption performance and low vertical deformation of the conventional jogging area of the plastic venue, can better protect the joints of the athletes in the warm-up process and is beneficial to improving the competition achievements of the athletes. The preparation method of the polyurethane composition is easy and practical and is easy to implement.

Description

technical field [0001] The invention relates to a polyurethane composition, in particular to a polyurethane composition used in a jogging area of ​​a plastic field and a preparation method thereof. Background technique [0002] Polyurethane plastic sports venues are indispensable and important facilities in modern track and field venues, also known as all-weather sports venues, which are composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, fillers, etc. . Compared with the traditional soil sports field, it has the characteristics of good elasticity, wear resistance, non-slip, and not affected by climate conditions. It is popular with the public and is also the development direction of modern sports field construction. Based on the above advantages, plastic courts were quickly adopted by major track and field venues soon after they came out, and some universities and middle schools have also wide...
