Abstract

The invention discloses a silicon PU (polyurethane) elastic floor structure and a manufacture method thereof. The silicon PU elastic floor structure comprises a basic layer, a waterproof bottom coating layer, a silicon PU elastic layer and a wear-resistance covering layer arranged sequentially from bottom to top; TPEE (thermoplastic elastomer) particles are added to the silicon PU elastic layer. The manufacture method includes: 1) pretreating the basic layer; 2) applying the waterproof bottom coating layer; 3) spreading the silicon PU elastic layer; 4) applying the wear-resistant covering layer. The silicon PU elastic floor structure has high strength, moderate hardness and elasticity, good resilience and toughness, good yellowing resistance, stable performance and the like, and is widelyapplicable to the sports sites, such as basketball courts, tennis courts, and badminton courts.

Description

technical field [0001] The invention relates to a silicon PU elastic ground structure and a manufacturing method thereof. Background technique [0002] With the rapid development of our country's social economy and the rapid improvement of people's living standards, more and more attention has been paid to physical fitness, and the concept of national fitness is gradually gaining popularity among the people. At present, no matter in cities or in rural areas, different types of sports venues are built, mainly to provide convenience for fitness and competitions. Among all kinds of sports venues, stadiums are very popular among sports fans. Most of the traditional courts use plastic, cement or wooden floors as surface materials. These surface materials have obvious defects, such as: the plastic surface has poor wear resistance, low stability, easy to dent, not resistant to high temperature, and rainy days Easy to slip, the wooden floor has poor water resistance, easy to mold,...
