Abstract

The invention discloses a silicone rubber / ethylene propylene diene monomer rubber-combined prefabricated runway coiled material which is prepared from the following raw materials: ethylene propylene diene monomer rubber, methylvinyl silicone rubber, a peroxide vulcanizing agent, nano calcium carbonate, light calcium carbonate, paraffin oil, polyethylene wax, zinc oxide, an anti-aging agent and pigments. The invention also discloses a preparation method of the silicone rubber / ethylene propylene diene monomer rubber-combined prefabricated runway coiled material. The raw material formula is simple and reasonable; the physical properties of the product have marked progress; the coiled material has the advantages of favorable weather resistance, favorable ultraviolet resistance, favorable self-cleaning property, environment friendliness, no carbon bisulfide residue and no secondary environment pollution. Compared with the common product, the tensile strength is enhanced by 3 times, the natural aging resistance can be enhanced by 2 times, the cold resistance can reach -60 DEG C, and the high temperature resistance can reach 150 DEG C. The product is suitable for laying athletic fields for competition, training and the like as well as physical fitness fields. The preparation method can effectively ensure the quality of the silicone rubber / ethylene propylene diene monomer rubber-combined prefabricated runway coiled material.

Description

technical field [0001] The invention relates to a rubber material, in particular to a prefabricated runway coil material combined with silicone rubber and EPDM rubber; the invention also relates to a preparation method of the prefabricated runway coil material combined with silicone rubber and EPDM rubber . Background technique [0002] The plastic runway can be applied to the pavement of various gymnasiums, track and field fields and other indoor and outdoor venues. Common runway materials in the prior art have complex technical processes, high energy consumption, and low physical properties. Some use prefabricated coils made of ordinary natural rubber and synthetic rubber (styrene-butadiene rubber, butadiene rubber). Heavy metals and organic volatiles (benzene, xylene, aromatics) in such products are seriously exceeded, seriously endangering the health of exercisers. It cannot fully meet the paving requirements of high-end gymnasiums, track and field and other indoor an...
