Abstract

The invention relates to a method for producing a high-quality sports rubber running track by utilizing a papermaking rubber roller leftover material. The rubber running track is prepared from the following effective components in parts by weight: 15 to 20 parts of rubber roller cuttings, 25 to 30 parts of polyurethane prepolymer, 20 to 25 parts of mixed polyether, 10 to 15 parts of polyethylene granules, 8 to 12 parts of pigment, 5 to 8 parts of auxiliary agent, 12 to 18 parts of asphalt and 15 to 20 parts of filler. The rubber running track provided by the invention has the characteristics of turning waste into treasure, aging resistance, exposure resistance, stable structure, good shock absorbing effect, non-toxicity, high elasticity, softness, skid resistance, collision resistance and the like.

Description

technical field [0001] The invention relates to the field of preparing a rubber track, in particular to a method for preparing a high-quality sports rubber track by using leftovers from papermaking rubber rollers. Background technique [0002] Although the popular rubber runway in the society is an innovation and revolution to the traditional polyurethane runway, there are still many deficiencies in use. Under the conditions of harsh outdoor climate changes and environmental changes, various factors such as bacteria, viruses, oxidation, and chemical reactions continue to attack the rubber track that has been laid outdoors for many years, resulting in a sharp decline in the wear resistance and aging resistance of the rubber track, which seriously affects the sports effect. , Reduce the service life, therefore, cause (environmental pollution during production, etc.) waste of materials. More importantly, because the runway cannot be cleaned and sterilized frequently, the runwa...
