Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a test device for the surface material of the sports field, which solves the problem that the test device used in the production process of the current plastic runway is usually only a simple reciprocating extrusion test on the surface of the material. In actual use, the runway needs to be squeezed from multiple angles, which leads to the problem that the detection cannot fit the reality and the accuracy of the test results is poor.

Description

technical field [0001] The invention relates to the technical field of testing surface materials of sports fields, in particular to a testing device for surface materials of sports fields. Background technique [0002] The sports field is the best place to exercise. The surface of the sports field is generally laid with a rubber runway to enhance the friction between the ground and the athletes. The plastic runway is also called an all-weather track and field track. It is made of polyurethane prepolymer, mixed polyether, and waste tires. Composed of rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers, the plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. To improve sports performance and reduce the rate of falls, the plastic track is composed of polyurethane rubber and other materials, which has certain elasticity and color, and has certain UV re...
