Problems solved by technology

Since the airtightness of the tire innerliner has a good correlation with the thickness, increasing the thickness will increase the airtightness or reduce the air permeability, so in order to further improve the airtightness of the innerliner, the general method is to increase the airtightness The thickness of the inner layer, but the increase of the thickness of the inner inner layer will bring three adverse effects: one is the increase of the cost of the tire; second, the increase of the thickness should avoid air bubbles in the molding process; The increase in tire weight will reduce the heat dissipation performance of the tire, the high-speed performance and the fuel consumption of the car
In addition, the pure bromobutyl rubber formula also has many disadvantages in production and use: uneven dispersion of carbon black and small materials, poor adhesion with the transition layer, and easy to appear bubbles when laminating

Abstract

The invention discloses an air-barrier glue for all-steel-wire truck radial tires, as well as a preparation method thereof. The glue comprises the following components in weight portion: 60 to 80 portions of natural glue, 20 to 40 portions of butadiene-styrene rubber, 40 to 65 portions of carbon black N660 as a reinforcing agent, 3 to 7 portions of zinc oxide as an activator, 1 to 4 portions of stearic acid, 2.5 to 5 portions of 204 resin as a tackifier, 2 to 5 portions of homogenizing agent UB4000 or 2 to 5 portions of homogenizing agent 40MSF, 0.5 to 2 portions of antiager 4020, 0.5 to 2 portions of antiager RD, 1 to 3 portions of protective wax, 2 to 4 portions of aromatic oil as a softening plasticizer, 0.5 to 1.0 portions of sulfur as a vulcanizing agent and 1.0 to 3.0 portions of accelerator NS or 1.0 to 3.0 portions of accelerator TBBS.

Description

technical field [0001] The invention discloses an inner liner adhesive of an all-steel wire load radial tire, and also discloses a preparation method of the inner liner adhesive of an all-steel load radial tire. Background technique [0002] Generally, the inner liner of radial tires uses natural rubber / chlorinated butyl rubber, natural rubber / brominated butyl rubber in combination, or chlorinated butyl rubber and brominated butyl rubber are used alone. The airtightness is quite good. Since the airtightness of the tire innerliner has a good correlation with the thickness, increasing the thickness will increase the airtightness or reduce the air permeability, so in order to further improve the airtightness of the innerliner, the general method is to increase the airtightness The thickness of the inner layer, but the increase of the thickness of the inner inner layer will bring three adverse effects: one is the increase of the cost of the tire; second, the increase of the thi...
