Problems solved by technology

[0002] Various sports venues, especially stadiums, are one of the sports venues for sports fans. Because the stadium is working almost every day, the service life of the stadium directly determines its performance. Therefore, the base surface design of the stadium is particularly important; In the prior art, plastic, cement or wooden floor courts are generally used. However, these courts have poor wear resistance and poor elasticity, and the base surface of the court is easy to sag and the court is easy to slip. , it has very good elasticity, and also has a certain wear resistance, sports fans should not be injured when exercising on the court, but the surface of the existing silicon PU court is soft, sticky and lacks sports texture under sunlight, and is not Accompanied by pungent smell, unable to provide sports fans with a comfortable and stable sports environment

Embodiment 1

[0015] The silicon PU type plastic court includes a base layer, a waterproof layer, a silicon PU elastic layer and a finish paint protective layer. The silicon PU elastic layer is composed of a leveling layer and a strengthening layer, and the construction is carried out according to the following steps.

[0016] a. Base layer treatment: clean the asphalt concrete foundation and cement concrete foundation, then rinse with 7-9% hydrochloric acid aqueous solution, rinse with clean water, then dry, and finally fill the expansion joint with silicon PU elastic material ;

[0017] b. Waterproof layer: roll-coat the silicon PU primer on the base layer, and roll-coat 0.15kg to 0.25kg of silicon PU primer per square meter;

[0018] c. Silicon PU elastic layer: add 10-20% quartz sand to the silicon PU elastic material, mix and stir evenly, and then apply it on the waterproof layer with a rake or trowel to form a leveling layer. After the leveling layer is dry, Use the water accumulatio...
