  • Patent number: 11634563
    Abstract: The present disclosure provides an epoxidized natural rubber composite and a preparation process thereof, and relates to the technical field of rubber materials. The epoxidized natural rubber composite provided by the present disclosure comprises the following preparation raw materials in parts by weight: 100 parts of epoxidized natural rubber, 1˜30 parts of peanut meal, 0.05˜0.8 parts of surfactants, 0.1˜4 parts of coagulant and 0.2˜12 parts of vulcanization processing aids. The present disclosure utilizes essential amino acids and non-essential amino acids contained in peanut meal to improve the aging resistance of the epoxidized natural rubber. After hot air aging, ozone aging and ultraviolet aging treatments, both the tensile strength retention rate and the elongation at break retention rate of the epoxidized natural rubber composites of the present disclosure can be kept above 83%.
    Type: Grant
