Production Process of Tin Bronze Tempered Bead Wire Highly Bonded to Rubber

Abstract

The invention discloses a production process of tin bronze tempered bead steel wire highly bonded to rubber, comprising the following steps: ①, selecting the steel wire; ②, tempering treatment; ③, electrolytic pickling; ④, copper-tin alloy plating ; ⑤, washing and drying; ⑥, coating water base coating solution; ⑦, coating organic coating; ⑧, take-up. The silane coupling agent in the water base coating liquid used in this process, the hydrolyzed group at one end of the molecular chain is hydrolyzed and combined with the steel wire matrix, and the organic group at the other end can react with the organic components in the post-treatment process. Effectively connect inorganic metal and organic resin, improve the adhesion between bead wire and rubber, the adhesive rate on the surface of the steel wire after bonding, and prolong the storage time of the steel wire.

Description

technical field

[0001] The invention relates to a production process of bead steel wire. Background technique

[0002] In recent years, the automobile industry has developed rapidly. As an important part of automobiles, radial tires have been rapidly applied and developed due to their advantages of energy saving, high speed and light weight. As one of the frame materials of radial tires, the quality of the bead wire will directly affect the overall performance of the tire. Bead wires are subject to extremely complex alternating loads and impact loads in tires. Not only are they required to have high strength, good fatigue resistance, and high impact resistance, they also need to be compatible with them during later use. Rubber has strong and stable adhesive properties, which requires that the bead wire should not only be firmly bonded to the rubber, but also not be separated prematurely during use. The adhesion between smooth steel wire and rubber is extremely poor, so the...
