A kind of water-based coating solution for post-plating treatment of bead steel wire

Abstract

The invention discloses a water-based first coating for tire bead steel wire plating aftertreatment. The water-based first coating is prepared from at least one of N-beta (aminoethyl)-gamma-diethylaminopropyl-methyldimethoxysilane (triethoxyl silicon propyl) tetrasulfide, bi(triethoxyl silicon propyl) disulfide and 3-sulfo-octanoic acid-1-propyl triethoxyl silane, as methanol, ethanol and water. Hydrolysis groups at one end of the molecular chain of the silane coupling agent in the water-based first coating are subjected to hydrolysis and react with a steel wire substrate so as to be combined together, and organic groups at the other end of the molecular chain can react with organic components in an aftertreatment process, so that inorganic metal and organic resin are effectively connected; when the water-based first coating is applied to tire bead steel wire plating aftertreatment, the adhesive force of a tire bead steel wire and rubber can be effectively improved, the adhesive adhesion rate of the surface of the adhered steel wire is increased, and the preservation time of the steel wire is prolonged.

Description

technical field

[0001] The present invention relates to a water base coating solution for the post-plating treatment of bead steel wires, in particular to a water-based coating solution capable of coupling with inorganic metal steel wires and organic resins at the same time, thereby improving the adhesion between bead steel wires and rubber Water base coat. 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 durin...
