Problems solved by technology

Steam vulcanization requires high-temperature and high-pressure steam as a heat source, and superheated water or nitrogen is used to provide internal pressure, which consumes a lot of energy. At the same time, in the process of dipping and coating, the volatilization of solvents and cooling also restricts the automatic continuous production of tires. efficiency

Embodiment 1

[0023] The formula of the rubber layer of radial tire traveler parts: natural rubber 100, carbon black (660) 60, carbon black (N330) 30, zinc oxide 10, stearic acid 1.5, antioxidant (4010NA) 2, petroleum resin (C5) 7, Oil-extended insoluble sulfur (IS-7020) 4, accelerator (CZ) 2.0, accelerator (TMTD) 0.5.

[0024] The dosage units of the above components are in parts by mass.

[0025] Mix the rubber base material, anti-aging system, reinforcing system, adhesive system, vulcanization system, etc. with an internal mixer according to the above formula. The mixing temperature is 80°C, and the mixing time is 30 minutes. After mixing the rubber evenly Glue removal; after parking for 8-12 hours, add vulcanization system to the open mill to complete the preparation of compound rubber. According to the radial tire traveler production process, the copper-plated steel wire is extruded and glued to make a single-layer or multi-layer rubber-coated steel wire belt. The tire steel wire bel...

[0028] The formula of the rubber layer of radial tire traveler parts: natural rubber 100, carbon black (660) 60, carbon black (N330) 30, zinc oxide 10, stearic acid 1.5, antioxidant (4010NA) 2, petroleum resin (C5) 7, Oil-extended insoluble sulfur (IS-7020) 4, accelerator (CZ) 1.5, accelerator (TMTD) 0.5.

[0029] The rubber material mixing process, tire traveler extrusion coating preparation process and radiation pretreatment process are the same as in Example 1.

[0030] In this example, after adjusting the vulcanization system of the tire bead ring composition, the tire bead ring components are subjected to radiation pretreatment, and the various performances of the bead ring components are tested, which proves that the radiation pretreatment technology is used for the treatment of tires. After the pre-vulcanization of the traveler parts, in addition to significantly improving the quality of the product, it can also effectively reduce the amount of vulcanization system, and...

Abstract

The invention discloses a meridian tire wire loop component and the manufacturing process thereof. Rubber base material, an anti-aging system, a reinforcement system, an adhesion system, a vulcanizing system and radio sensitizer are mixed in proportion to make a mixture. The rubber mixture is compounded in a banbury mixer. Glue is applied on a coppered steel wire based on the manufacturing technology of the tire wire loop to make the glue-coated steel wire band for meridian tire. An electron accelerator is used for producing a beam current to irradiate the glue-coated steel wire band of the meridian tire under the effect of a constant tension traction apparatus. The meridian tire wire loop component is vulcanized under the condition of luminous irradiation. After being irradiated, the crude rubber of the meridian tire wire loop component has strong Green strength and stable structural size and performance. Furthermore, steel wire withdrawal force is improved and the adhesive strength of the adhesive layer of a steel wire loop is enhanced, so the quality of a tire is improved. In addition, irradiation dose is small, the manufacturing cycle of products is shortened and production efficiency is high, thus being beneficial to environmental protection.

Description

Technical field [0001] The invention relates to the technical field of rubber tire processing, in particular to a bead ring component of a radial tire and a preparation process thereof. technical background [0002] Tires are one of the most important components of a car. They are in direct contact with the road surface, and work together with the car suspension to ease the impact of the car while driving, ensuring that the car has good ride comfort and ride comfort, and guarantees The wheels and the road have good adhesion, improve the traction, braking and passability of the car, and bear the weight of the car. The importance of tires on a car is self-evident. The tire is made of rubber material as the main base material. After combining multiple parts, it is shaped by vulcanization process. There are many types of tires, among which radial tubeless tires are widely used. Braking torque, sideslip and centrifugal force, as well as the complex stress caused by the cooperat...
