Embodiment Construction

[0010] See figure 1 In the present invention, 30% of the volume of polyphenyl foam particles are uniformly mixed in a polyurethane elastomer viscous liquid at 60-70°C, and the particle size of the polyphenyl foam particles is Φ0.5mm. Stir evenly, a polyurethane polystyrene foam mixture 1 in a viscous liquid state. Then, the polyurethane-polystyrene foam mixture 1 in a viscous liquid state is scraped on the flow belt base 6 through the scraper 5, and the thickness of the polyurethane-polyphenyl foam mixture 1 is 3mm-25mm by the scraper 5. The polyurethane polystyrene foam mixture 1 is sent from the belt base 6 into the 70°C low-temperature drying tunnel 2 and heated in the drying tunnel 2 for 40 minutes, and the polyurethane liquid is cured. Then, the belt base 6 sends the cured polyurethane polystyrene foam mixture 1 into a high-temperature drying tunnel 3 at 80° C.-90° C., where it is heated for 10 minutes. The polyphenyl foam particles disappeared, and the polyphenyl foam p...

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 surface coiled 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 materials for sports grounds in sports venues, in particular to a manufacturing process of elastomer materials for manufacturing sports grounds. Background technique [0002] In order to increase the elasticity of the polyurethane elastomer sports ground and reduce the cost, the polyurethane material is generally mixed with a foaming agent during production. Generally speaking, the larger the cell, the better the elasticity. However, because it is an open cell, if the cell is enlarged, the cell will easily collapse and be difficult to form, which will affect the flatness of the ground. Therefore, in order to ensure the uniform thickness, the production of the elastic sports ground needs to be formed by a mold, which is relatively expensive. Moreover, it is easy to enter and store water in the bubbles, which not only affects the performance of the athletes, but also directly affects the service life of th...
