Problems solved by technology
But because it is an open cell, if the cell expands, the cell is easy to collapse, it is difficult to form, and it will affect the flatness of the ground
Therefore, in order to ensure consistent thickness, the production of the elastic sports ground needs to be formed by molds, which is costly
Moreover, water is easy to enter and store in the cells, which not only affects the performance of athletes, but also directly affects the service life of the sports ground.

Embodiment Construction
[0010] see figure 1 , the present invention uniformly mixes 30% of its volume polystyrene foam particles in the viscous liquid of polyurethane elastomer at 60-70°C, and the particle size of the polystyrene foam particles is Φ0.5mm. Stir evenly to form a viscous liquid polyurethane polystyrene foam mixture 1. Then, the viscous liquid polyurethane-polyphenylene foam mixture 1 is scraped on the flow belt base 6 by the scraper 5, and the thickness of the polyurethane-polyphenylene foam mixture 1 scraped by the scraper 5 is 3 mm to 25 mm. The polyurethane-polystyrene foam mixture 1 is sent from the belt base 6 to a 70°C low-temperature drying tunnel 2, and is heated in the drying tunnel 2 for 40 minutes to solidify the polyurethane liquid. Then the tape base 6 sends the cured polyurethane polystyrene foam mixture 1 into a high-temperature drying tunnel 3 at 80° C. to 90° C., and heats it in the drying tunnel 3 for 10 minutes. The polyphenylene foam particles disappear, and the po...

Abstract
The invention relates to a process for producing elastomer materials of a sport ground surface. The process includes that polystyrene foam particles are mixed evenly in viscous liquids of a polyurethane elastomer, a polyurethane polystyrene foam mixture in viscous liquid state is coated on a flow base; the base is used for conveying the polyurethane polystyrene foam mixture in viscous liquid state to a low-temperature drying channel to be heated and leading polyurethane liquids to be solidified, the base can convey the solidified polyurethane to a high-temperature drying channel to be heated;the polystyrene foam particles are vitrified to membranes to be adhered on porous walls of closed-cell foam cells, thereby forming the closed-cell foam cells, and finally forming sport ground surfacecoiled materials with uniform foam cells, uniform thickness and good elasticity. The process has the advantages of hardly aging and modified materials without using molds to foam, comparatively long service life, excellent elasticity, simple process and comparatively low cost.
Description
technical field [0001] The invention relates to a manufacturing process of a material for a sports ground, in particular to a manufacturing process of an elastic body material for a sports ground. Background technique [0002] In order to increase the elasticity of the polyurethane elastomer sports floor and reduce costs, foaming agents are generally mixed with polyurethane materials during production. Generally speaking, the larger the cell, the better the elasticity. But because it is an open cell, if the cell expands, the cell is easy to collapse, it is difficult to form, and it will affect the flatness of the ground. Therefore, in order to ensure consistent thickness, the elastic body sports ground needs to be molded with the help of molds, and the cost is relatively high. Moreover, water is easy to enter and store in the cells, which not only affects the performance of athletes, but also directly affects the service life of the sports ground.
