Abstract

The invention relates to the field of rubber tires, in particular to a tire stock and a mixing method as well as application thereof. The tire stock of an IPN (Interpenetrating Polymer Network) crosslinked structure is prepared by mixing the following raw material components in part by weight: 100 parts of first network material, 0.1-30 parts of second network material, 0.8-20 parts of co-meltingassistant, 20-150 parts of carbon black, 1-30 parts of activating agent, 0-50 parts of softening agent, 0-20 parts of anti-aging agent, 0.1-10 parts of vulcanizing agent and 0.1-20 parts of vulcanization accelerator, wherein the first network material is one or the combination of more selected from diene rubbers; and the second network material is selected from natural resin or synthetic resin providing a crosslink bond and monomer of the synthetic resin. In the invention, the advantages of superior temperature resistance, high shear strength resistance and high torsion deformation resistanceof an IPN vulcanization network bond are integrated while each item of physical performance and processing performance of the conventional single sulfur crosslink bond are kept; and the service performance of a tire formula is improved to the greatest extent.

Description

technical field [0001] The invention relates to the field of rubber tires, in particular to a tire compound and its mixing method and application. Background technique [0002] Under normal circumstances, the rubber formula of each component of the rubber tire is mainly made of diene natural rubber or diene synthetic rubber. Therefore, when designing the vulcanization system, it is mostly a sulfur vulcanization system. , the cross-linking bond is mostly a single cross-linking bond, such as the most common semi-effective and effective sulfur vulcanization system used in tire formulations, the cross-linking bond is a single "-S Ｘ -" key, (the "X" can be different numbers from 1 to 6 according to the performance requirements); another example is the peroxide vulcanization system occasionally used in the formula of rubber miscellaneous parts, and its cross-linking bond is a single "-C-C-" key and so on. [0003] IPN technology is a polymer chain winding mixed system obtained b...
