Description

A double-layer conformal sports ground mat

technical field

The utility model relates to the field of sporting goods, in particular to a double-layer shape-preserving sports field mat.

Background technique

At present, the running track, basketball court, tennis, badminton and other sports are generally covered with a layer of sports field mats on the ground. The sports field mats are made of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, Composed of pigments, additives and fillers, it has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which is conducive to the performance of athletes' speed and skills, effectively improving sports performance and reducing the rate of falls. This kind of sports field mat contains benzene, lead, mercury and other elements, which have certain toxicity, are not recyclable, and are not environmentally friendly, and there will be internal stress inside after molding. Cracking and warping deformation also affect its mechanical properties, optical properties, electrical properties and appearance quality. Cracking: Due to the existence of stress, after being subjected to external effects (such as contact with chemical solvents during pad printing or high temperature baking at the back end of baking paint), it will induce stress release and crack at the residual stress position, and the cracking is mainly concentrated at the gate. or overfilled. Warpage and deformation: Due to the existence of residual stress, the product will have a long-term internal stress release at room temperature or a short-term residual stress release process at high temperature. Residual locations produce warping or deformation problems. Product dimensional change: Because of the existence of stress, during the process of product placement or post-processing, if the environment reaches a certain temperature, the product will change due to stress release.
