Surface active agent in steel wire pickling solution

Abstract

The invention discloses a surface active agent in steel wire pickling solution. The surface active agent comprises any or combination of two or more in alkylbenzene sulfonate, alkane sulfonate, alkyl glycoside, aliphatic alcohol phosphate, fatty alcohol-polyoxyethylene ether and alkylphenol polyoxyethylene, and the mass percent of the surface active agent is 0.01-2.5% in hydrochloric acid pickling solution. After being prepared into the pickling solution together with the hydrochloric acid, the surface active agent can be used for carrying out acid pickling on a steel wire; compared with the hydrochloric acid pickling solution which does not contain the surface active agent, the pickling solution containing the surface active agent obviously improves the pickling efficiency and saves the pickling time; after pickling, the oxide skin on the surface of the steel wire can be more thoroughly removed, and the surface of the steel wire is more uniform; after chemical planting, the bonding force between the steel wire and the rubber is higher.

Description

technical field [0001] The invention relates to a method for treating the surface of bead steel wire before plating, in particular to a surface that can quickly wet the oxide skin on the surface of the steel wire, increase the release speed and expansion area of ​​hydrochloric acid in the pickling solution, and thereby improve the utilization rate of hydrochloric acid in the pickling solution. active agent. Background technique [0002] In the pickling process of steel materials, the pickling solution first needs to soak the oxide skin on the surface of the steel wire, and then when the pickling solution further penetrates the oxide scale, the oxide scale and the pickling solution chemically react to achieve the effect of removing the oxide scale on the surface of the material. Purpose. In the existing pickling process of bead steel wire after tempering, the steel wire enters the pickling solution, and the pickling solution wets and penetrates the oxide scale on the steel w...

Problems solved by technology

[0004] In the current conventional bead wire production technology, electrolytic pickling is usually used before electroless plating. Electrolytic pickling is likely to cause "hydrogen embrittlement" of bead wires with high carbon content, which affects the service life of bead wires. ; At the same time, the conventional pre-plating treatment method is also easy to cause uneven unevenness on the surface of the steel wire, which affects the quality of the subsequent coating and reduces the adhesion between the bead steel wire and the rubber.
