Abstract

All-steel radial truck tire air-tight layer consists of (by weight percentage) montmorillonite / SBR nano composite material 160-200, silane coupling agent 0.4-0.6, 1.5-2.5 stearic acid, zinc oxide 2-4, B type microcrystalline wax 6-10, anti-aging agent 6PPD 1.5-2.5, anti-aging agent TMQ 1.5-2.5, octyl phenolic tackifying resin 6-10, accelerator NS 0.6-1, and sulfur 1-2. In the mixing process, silane coupling agent is added to perform interaction on silicon hydroxyl of a montmorillonite layer, to weaken network packing structure formed by the interaction between montmorillonite, improve binding force between montmorillonite and rubber, thereby improving the rubber tackiness, reducing the hardness, and improving material properties. Material tackiness can be further improved via adjusting the curing system, adding operation oil and tackifying resin, to improve theproperties of rubber compound.

Description

technical field [0001] The invention relates to an all-steel load-bearing radial tire, in particular to an all-steel load-bearing radial airtight layer and a preparation method thereof. Background technique [0002] Since halogenated butyl rubber has good airtightness, it has always been the first choice material for inner liner formulations. With the development of my country's tire industry, the demand for brominated butyl rubber is increasing day by day, but currently my country's brominated butyl rubber is mainly It also relies on imports, so the price of bromobutyl rubber has remained high for a long time. However, there has not been a new type of raw material in the market that can replace bromobutyl rubber in large quantities, mainly because the air tightness is not good enough, and the self-adhesive and aging resistance of the rubber are not good enough. Invention content: [0003] The technical problem to be solved by the invention is that the airtightness of the ...
