Abstract
The invention discloses a low-heat-generation rubber composition, belonging to the technical field of rubber preparation. The invention particularly relates to the low-heat-generation rubber composition and a preparation method thereof. The rubber composition is characterized by comprising the following components in parts by weight: 95-105 parts of natural rubber, 32-36 parts of carbon black, 12-18 parts of white carbon black, 2-5 parts of zinc oxide, 0.7-1.2 parts of stearic acid, 0.7-1.2 parts of an anti-aging agent RD, 1.2-2 parts of an anti-aging agent 4020, 2-5 parts of tackifying resin, 1-1.6 parts of N-tert-butyl-alpha-benzothiazole, 0.1-0.3 part of 3-diphenylguanidine, 0.6-1.2 parts of 4,4'-dithiodimorpholine, 2.1-2.6 parts of sulfur and 1-5 parts of methylated hexamethylolmelamine resin. The rubber composition of the invention has the positive effect of reducing the heat generation of rubber while ensuring the autohension of a rubber compound.
Description
technical field [0001] The invention belongs to the technical field of rubber preparation, in particular to a low heat generation rubber composition and a preparation method thereof. Background technique [0002] With the development of the rubber industry, the amount of synthetic rubber has increased rapidly, and the requirements for rubber adhesive properties have also become higher and higher. When the tackifier in the prior art is applied to the rubber tire, the rubber will undergo repeated deformation with a large amplitude and high frequency during the rolling process of the tire, resulting in the generation of considerable heat, which will cause the temperature to rise, resulting in Tire tread delamination, internal aging and other problems. Contents of the invention [0003] The object of the present invention is to provide a low heat generation rubber composition and its preparation method, so as to achieve the purpose of reducing rubber heat generation while ens...
