Abstract
The invention relates to a raw material formula of a type-A automobile tire, and solves the problem that the physical mechanical properties of the traditional type-A automobile tire are not stable due to the raw materials. The raw material formula comprises the following raw materials by weight: 30-70 parts of NR (natural rubber), 30-70 parts of SBR (styrene butadiene rubber), 15-30 parts of N330 carbon black, 10-20 parts of N660 carbon black, 5-20 parts of sericite powder, 2-8 parts of zinc oxide, 1-5 parts of stearic acid, 0.5-2 parts of antioxidant 6PPD, 0.5-2 parts of antioxidant TMQ , 0.5-2 parts of modified wax, 1-3 parts of physical peptizer WP-1, 3-9 parts of aromatic hydrocarbon oil, 3-8 parts of hydrocarbon resin, 0.5-3 parts of sulfur, 0.5-1 part of accelerant CZ, and 0.1-0.5 part of accelerant TMTD. The formula is scientific; the proportioning is reasonable; and the raw materials are easily obtained. The type-A automobile inner tire produced by the raw material formula is stable in the physical mechanical properties; and the comprehensive performances can meet the national standards.
Description
technical field [0001] The invention relates to an unspecified rubber composition, in particular to a raw material formulation of an A-type automobile inner tube. Background technique [0002] We know that pneumatic tires are divided into inner tube tires and tubeless tires according to having and tubeless tires; inner tube tires include outer tires, inner tubes and pads. As an integral part of a pneumatic tire with an inner tube, the inner tube is a circular rubber cylinder, which is installed on the rim together with the outer tire, and works together with the outer tire after being filled with compressed air. It mainly supports the outer tire and eases the impact of driving. and vibration effects. When inflated, each part of the inner tube bears different deformations, the outer diameter part bears stretching deformation, the joint part bears compression deformation, and the section direction also bears stretching deformation. And it is installed in the outer tire, and ...
