Abstract

The invention relates to the technical field of materials, and relates to a material use method and a paving preparation method of sports field. The invention particularly relates to a water-based silicon polyurethane (PU) adhesive applicable to pavement of sports fields and a production method of the water-based silicon PU adhesive. The water-based silicon PU adhesive disclosed by the invention is reasonable in formula, and the product meets the requirements specified in the stand of GB / 14833-2011 (synthetic materials track surfaces). The performance indexes of impact absorption, vertical deformation and anti-slip value items, index requirements, compression recovery rate and rebound value performance all exceed the standard requirements. A track paved by using the material disclosed by the invention has a good damping effect in the aspect of track buffer property, so that sports injury caused by reactive force to ankles, joints and ligaments from the ground can be effectively relieved. Long-time dehydration treatment is adopted, so that the content of volatile organic compounds is greatly reduced, the content of volatile harmful substances such as benzene, formaldehyde and the like is lower than the national specified standard, and true odorlessness and harmlessness are achieved under sun exposure.

Description

technical field [0001] The invention relates to the technical field of materials, and relates to the use of materials and a preparation method for laying sports grounds. Specifically, it is a water-based silicon PU glue suitable for laying sports grounds and a production method thereof. Background technique [0002] Plastic track is also called all-weather track and field sports track. The plastic track has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to improving the speed and technical performance of athletes and effectively improving sports performance. It is also beneficial to reduce the injury rate of athletes and protect the safety of athletes. Existing plastic runways will experience performance degradation, partial damage, and reduced stability after being used for a period of time. [0003] In addition, as the market has higher and higher requirements for the e...
