Problems solved by technology

[0002] The traditional runway is made of rubber particles and polyurethane cast on site. Its flatness, compactness, wear resistance and aging resistance are not good, and it is easy to discolor, degranulate, and accumulate dust. The polyurethane component is polluting to the environment. and toxic volatilization
At present, there are also composite runways, but the products are mainly made of natural rubber, supplemented by reinforcing fillers and other additives, the process is complicated, the cost is high, the product has high tensile strength, aging resistance, and poor resistance to sunlight cracking , easy to fade, shock absorption, wear resistance, impact absorption effects need to be improved

Abstract

A composite rubber racetrack is prepared from baypren, natural rubber, ethylene propylene rubber, the rubber powder made of used tyre, white carbon black, pottery clay, zinc oxide, stearic acid, naphthenic oil, dioctylester, flame retardant, ultraviolet absorbent and sulfurizing promoter through proportional mixing, adding sulfur, forming sheet, sticking the rubber liner made of regenerated rubber, sulfurizing, cutting for removing edges, grinding, examining and packing.

Description

1. Technical field [0001] The invention relates to a sports facility, in particular to a method for manufacturing a composite rubber track. 2. Technical Background [0002] The traditional runway is made of rubber particles and polyurethane cast on site. Its flatness, compactness, wear resistance and aging resistance are not good, and it is easy to discolor, degranulate, and accumulate dust. The polyurethane component is polluting to the environment. And toxic volatilization. At present, there are also composite runways, but the products are mainly made of natural rubber, supplemented by reinforcing fillers and other additives, the process is complicated, the cost is high, the product has high tensile strength, aging resistance, and poor resistance to sunlight cracking , easy to fade, shock absorption, wear resistance, impact absorption effects need to be improved. 3. Contents of the invention [0003] The purpose of the present invention is exactly to overcome the short...
