Abstract

The invention discloses tyre inner lining glue with a graphene / carbon black composite and a preparation method of the tyre inner lining glue. The tyre inner lining glue comprises the components in parts by weight of 100 parts of halogenated butyl rubber, 1-20 parts of a graphene / carbon black composite, 10-60 parts of a filling, 1-20 parts of extender oil, 1-10 parts of a viscosifying agent, 1-5 parts of a processing agent, 1-10 parts of an activator and 0.9-5 parts of a vulcanization system, wherein the graphene / carbon black composite is prepared by a home-position mechanical exfoliation method, self clumping between graphene slices is overcome, and the dispersibility and the compatibility of graphene and carbon black in rubber can be improved. In a tyre inner lining formula, the graphene / carbon black composite is added, and in a banburying mixing manner, the graphene is uniformly distributed in a polymer, so that the effect of separating gas molecules from infiltrating is achieved, the air tightness of the tyre is improved greatly, the service life of the tyre is prolonged, and the using properties of vehicles can be improved in many respects.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials and rubber, and in particular relates to a tire inner-layer adhesive added with graphene / carbon black composite materials and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, tires tend to be tubeless, and the requirements for tire airtightness are getting higher and higher. In the traditional airtight layer formula, halogenated butyl rubber is mainly used to improve the airtightness of the tire. However, because polymers have a certain degree of air permeability, the use of halogenated butyl rubber alone to improve airtightness has reached a certain limit. [0003] Carbon black is an important rubber reinforcing agent and filler, which can improve the mechanical properties and wear resistance of rubber products and prolong the service life of rubber. Therefore, carbon black reinforced halogenated butyl rubber i...
