Abstract

The invention relates to a high-adhesive-force PVC (polyvinyl chloride) plastic coating steel wire, comprising a steel wire and a PVC (polyvinyl chloride) plastic coating coated on the steel wire. The high-adhesive-force PVC (polyvinyl chloride) plastic coating steel wire is characterized in that an adhesive is coated between the steel wire and the PVC plastic coating; the adhesive comprises the following components by weight percent: 30-50 of dimethylbenzene, 10-35 of aromatic isocyanate, 10-40 of 4, 4'- diphenylmethane diisocyanate, 5-20 of methylene diphenyl diisocyanate, 5-15 of methyl isobutyl ketone and 5-30 of phenylethane. The high-adhesive-force PVC (polyvinyl chloride) plastic coating steel wire increases the adhesive force between the matrix steel wire and the PVC coating, improves the safety of the plastic coating steel wire, and prolongs the service life of the steel wire during practical use.

Description

Technical field [0001] The present invention involves a PVC coating steel wire, especially a high -bond PVC coating steel wire and its production method. Background technique [0002] PVC (polyvinyl chloride) is rich in raw materials, which is the second largest general resin in the world after PE (polyethylene) resin, accounting for 29%of the total resin consumption in the world.In our country, the consumption of PVC is the first of the five general resin, which is higher than the consumption of polyethylene.PVC is mainly used to produce plastic products such as artificial leather, thin film, wire guard, pipelines, and other plastic products.The surface coating of the wire can significantly improve its corrosion resistance, decorative, electrical insulation and other properties. It is widely used in the occasion of marine steel wire ropes, weaving metal mesh, and steel plastic pipe skeleton support. It has broad markets and application prospects.However, PVC is a non -polar poly...
