Polyester fiber grid cloth layer
The polyester fiber mesh cloth layer is used as a substrate layer of the TPU surface layer, the pore density of the substrate layer cannot be too large or too small, if the pore density is too small, the TPU can penetrate the polyester fiber mesh cloth layer when being cast and pressed down, the TPU permeates the bottom surface of the polyester fiber mesh cloth layer, and the first adhesive layer (PVC adhesive) below the polyester fiber mesh cloth layer cannot be coated and adhered on the polyester fiber mesh cloth layer (the difference between the TPU and the PVC cannot be directly compounded); if the hole density is too high, the TPU cannot effectively permeate into the polyester fiber mesh cloth layer, the combination firmness of the TPU and the polyester fiber mesh cloth layer is poor, and the peeling strength is low.
Aziridine curing agent
The aziridine curing agent is convenient for combining the PVC adhesive and the polyester fiber mesh cloth, improves the combination firmness of the PVC adhesive and the polyester fiber mesh cloth layer, and improves the peel strength of the sports floor.
Pressure-resistant layer
The pressure-resistant layer is made of high-polymerization polyvinyl chloride pasty resin; the pressure-resistant layer is a supporting layer and has high strength and shock resistance.
The first PVC pressure-resistant layer and the second PVC pressure-resistant layer are connected through the second adhesive layer in an adhesive manner without adopting a hot melting mode, so that the phenomenon that air in grid holes of the polyester fiber grid cloth is expanded due to the fact that the polyester fiber grid cloth layer is heated is avoided, the first PVC pressure-resistant layer generates bubble bulges, and the defective products of the sports floor are caused.
Glass fiber stabilization layer
The glass fiber stabilizing layer and the polyester fiber grid cloth layer can play a role in stabilizing, so that the dimensional stability of the product is ensured; the grid reinforcing structure ensures that the product is subjected to instant impact energy to disperse impact force, and prolongs the service life of the product.
Foaming bottom layer
The foaming bottom layer is a PVC calcium-free foaming bottom layer, the foaming holes are uniform and fine, the rebound performance and the shock absorption performance of the foaming bottom layer are improved, the safety of key parts of athletes can be better protected on the premise of guaranteeing the performance of floors, and the injuries and scratches of the athletes are prevented.
