Problems solved by technology

After the expiration date, the abandoned lawn must be recycled, otherwise it will cause huge waste of resources and environmental hazards
It can be seen from the existing technology that the current lawn system mainly consists of carboxylated styrene-butadiene latex or PU glue artificial turf, and IXPE foam pads. Among them, the IXPE foam pads are easy to bulge, and there is a danger of stepping on the air at the bulging area. During the process, athletes have a high risk of ankle sprains; the IXPE foam pad shrinks and deforms, and cracks appear at the seams, and athletes are prone to sprains during strenuous sports competitions; in heavy rain, the entire lawn system does not drain smoothly, resulting in accumulation water and many other issues
At present, high-end sports fields all need to lay a water distribution layer on the foundation to provide a drainage system, which requires a large amount of engineering and high cost, such as the structure of the sports field involved in patent CN107208384A

Abstract

The invention discloses a novel artificial turf system with high drainage performance. The system comprises an artificial turf and an elastic cushion layer on the bottom surface of the artificial turf, wherein the elastic cushion layer is a 3D cushion layer. According to the artificial turf system provided by the invention, the problem of shrinkage cracking at the joint of the artificial turf canbe solved; and meanwhile, the novel artificial turf elastic cushion has good drainage performance on the basis of keeping the original vibration absorption performance, vertical deformation performance and ball rolling performance, can be directly paved on the basis of cement, asphalt and foundation stone, does not need to be additionally provided with a drainage system, greatly reduces the engineering quantity, and reduces the manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of artificial turf, in particular to a novel artificial turf system with high drainage. Background technique [0002] In recent years, the artificial turf industry has developed vigorously, and its consumption has increased year by year, with an annual growth rate of 20-25%. The application of artificial turf has gone beyond stadiums and is widely used in various leisure and decoration fields. The amount of artificial turf in the world has reached more than 300 million square meters, of which artificial turf for sports accounts for about 50%. The general artificial turf is designed to have a service life of 5-8 years, and the special one can reach 8-12 years. After the expiration date, the abandoned lawn must be recycled, otherwise it will cause a huge waste of resources and environmental hazards. It can be seen from the existing technology that the current lawn system mainly consists of carboxylated styre...
