Abstract

The embodiment of the invention discloses a novel tire bead steel wire coating and a coating method thereof. The coating comprises the following raw materials: coumarone-indene resin, mixed xylene andacetone. The coating method comprises the specific steps of plating the surface of a tire bead steel wire with a tin bronze plating layer, drying by virtue of a drying device, and dipping the tire bead steel wire into an oil core containing the novel tire bead steel wire coating, so as to cover the surface of the novel tire bead steel wire coating with a novel resin coating layer. The novel tirebead steel wire coating is specially used for treating the surface of the tire bead steel wire so as to cover the surface of the steel wire with the protective resin coating layer, so that the oxidative rusting of the surface of the steel wire is effectively prevented, the service life of the tire bead steel wire is substantially prolonged, and the adhesive force of the tire bead steel wire to therubber is increased by 6%-8%.

Description

technical field [0001] The invention relates to the field of bead wire coatings, in particular to a novel bead wire coating and a coating method thereof. Background technique [0002] Bead wire is an important raw material used to make tires. However, there is a certain time interval between the delivery of the bead wire and the use before use. It needs to be properly packaged and stored to prevent the steel wire from being oxidized and rusted and affecting the combination of the steel wire and the rubber. performance. At present, the bead wire is usually packaged in a standard package when it leaves the factory, and is vacuumized and a desiccant is added therein to ensure that the bead wire does not rust during storage, transportation and before use. Even so, the storage of the above-mentioned treated bead wire has a validity period, and the validity period of the bead wire without any treatment after plating is only 1 month, which limits the output of the bead wire and is...
