Preparation method of pouring type prefabricated polyurethane elastomer sport field material

Abstract

The invention belongs to the technical field of athletic field materials, and particularly relates to a preparation method of a pouring type prefabricated polyurethane elastomer athletic field material. A casting machine comprises a base and a storage box. A storage box is fixedly connected to the upper surface of the left side of the base; a conveying belt is rotationally connected into the storage box through a motor; a long groove is formed in the inner wall of the storage box on the right side of the conveying belt and penetrates through the inner wall of the right side of the storage box;and a mounting groove is formed in the inner wall of the base on the right side of the storage box. According to the invention, the manufacturing method is mainly used for solving the problems that in the existing sports field material pouring process, due to accumulation of raw materials, the thicknesses of manufactured sports field materials are different; meanwhile, in the sports field material manufacturing process, a water-based adhesive solution is added, so that the product solves the problem that in the raw material pouring process, the raw materials are liable to be bonded and accumulated, the thickness of each part of raw materials is not uniform in the pouring process of the raw materials, and thereby the manufactured sport field materials are uneven.

Description

technical field [0001] The invention belongs to the technical field of sports field materials, in particular to a method for preparing a casting-type prefabricated polyurethane elastomer sports field material. Background technique [0002] The plastic runway material is composed of polyurethane prepolymer, mixed polyether, waste tire rubber or PU particles, pigments, additives, fillers to form the bottom layer, and EPDM rubber particles as the surface layer. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to athletes' speed and technical performance, effectively improving sports performance and reducing the rate of falls. The plastic runway is composed of polyurethane rubber and other materials. It has certain elasticity and color, and has certain anti-ultraviolet ability and aging resistance. It is internationally recognized as the best all-weather ou...

Problems solved by technology

[0005] In order to make up for the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a method for preparing a pouring type prefabricated polyurethane elastomer sports field material. Accumulation occurs between raw materials, which leads to differences in the thickness of the sports field materials produced. At the same time, when the present invention is making sports field materials, the water-based glue solution added will cause adhesion and accumulation of raw materials during the pouring process of raw materials, resulting in raw materials In the process of pouring, the thickness of the raw materials of each part is not uniform, which will make the material of the sports ground uneven.
