Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a wear-resistant and flame-retardant modified natural rubber. Background technique [0002] Natural rubber is obtained from the white latex of specific plants in tropical climate areas. It is an important industrial material and is widely used in transportation, industrial equipment, medical equipment, construction and other fields. In production, natural rubber is generally further processed by modified methods to make up for the shortcomings of high cost and poor physical and mechanical properties of natural rubber; at the same time, due to the rapid development of industry, the flame retardancy and wear resistance of rubber materials are required. Therefore, it is imperative to develop a rubber material with good wear resistance and flame retardancy. Contents of the invention [0003] The technical problems in the basic background technology, the present invention proposes a...
