Problems solved by technology

[0003] Steel wire bonding compound is an indispensable part in tire production, and the bonding system of the usual steel wire bonding compound uses resorcinol, adhesive RA or HMT, metamethyl white carbon black bonding system, or In addition, the cobalt-salt meta-methyl white cobalt adhesive system is used to increase the bonding effect between the rubber material and the steel wire, but resorcinol is easy to sublimate during the production of the rubber material, and there is a phenomenon of smoking, which reduces the resorcinol. Effective effect, affecting the bonding effect of rubber and steel wire, and at the same time causing environmental pollution and health damage to workers

Embodiment 1

[0028] The mixing method of steel wire bonded rubber compound for tires, the steps are as follows:

[0029] a) One-stage mixing: add natural rubber in the internal mixer, the internal mixer speed is 50 rpm, pressurize 17MPa, and lift the mound for 45s. At this time, the polymer materials of each component have been in a viscous flow state, and then, Put in zinc oxide, anti-aging agent 4020, 60% of the total mass of carbon black, adhesion promoter KOTA, adhesion antioxidant BW-60, white carbon black, pressurize, lift the weight when the temperature reaches 125°C, pressurize 17MPa , When it reaches 155℃, discharge the glue to get a section of mixed rubber.

[0030] b) Two-stage mixing: add one-stage mixing rubber and cobalt decanoate to the internal mixer, press the upper bolt for 35 seconds at the speed of the internal mixer at 40 rpm, lift the mound, add the remaining carbon black, pressurize at 17 MPa, and lift the pressure for 30 seconds. Mound, pressurized at 17MPa, and di...

Abstract

The invention belongs to the field of tires, and particularly relates to a steel wire adhesive material for a tire and a preparation method of the adhesive material. The steel wire adhesive material comprises the following raw materials in parts by weight: a first adhesive system comprising 1.0-2.5 parts of adhesion promoter, 4.0-6.0 parts of adhesive, 10 parts of white carbon black and 2.0-4.0 parts of adhesive antioxidant; a second adhesive system comprising 0.6-1.5 parts of cobalt salt, 100 parts of natural rubber, 35-55 parts of carbon black, 6-10 parts of zinc oxide, 1.0-2.5 parts of anti-aging agent, 4.0-6.0 parts of sulphur, 0.8-1.5 accelerant and 0-0.3 part of scorch retarder. Resorcinol is replaced with the adhesion promoter, and meanwhile, the adhesive antioxidant is added, so that the smoking phenomenon in production is removed, the adhesive effect of a sizing material and the steel wire is improved, and meanwhile, the environmental pollution and the damage to physical health of a worker are relieved.

Description

technical field [0001] The invention belongs to the field of tires, and in particular relates to a tire steel wire bonding compound and a preparation method thereof. Background technique [0002] As we all know, with the increasingly fierce market competition, consumers have higher and higher requirements on the quality of tires, and it is very important to improve the high-speed and durability performance of tires. The belt layer of the tire bears 60%-75% of the entire internal stress of the tire. The strength, stiffness, and bonding performance of the belt layer compound to the steel wire and the aging resistance after long-term driving are directly related to the tire's performance. service life. [0003] Steel wire bonding compound is an indispensable part in tire production, and the bonding system of the usual steel wire bonding compound uses resorcinol, adhesive RA or HMT, metamethyl white carbon black bonding system, or Add the cobalt methane white cobalt adhesive s...
