Example

[0027] Example 1: A production method of high-adhesion PVC coated steel wire, the steps are as follows:

[0028] (1) Wash the Φ3.0mm raw steel wire with 160℃ high temperature steam for 4 minutes to remove the lubricating powder and floating dust on the surface of the steel wire;

[0029] (2) The above-mentioned steam-cleaned steel wire is cleaned for 5 minutes by the alkali aqueous solution in the ultrasonic device to remove the oil and impurities on the surface of the steel wire; sodium hydroxide, sodium carbonate and trisodium phosphate are added to the alkali aqueous solution. The amount added is 50 g / L sodium hydroxide, 30 g / L sodium carbonate; 30 g / L trisodium phosphate; the temperature of the alkaline aqueous solution is 70℃ ;

[0030] (3). Clean the steel wire cleaned by the ultrasonic device in step (2) with hot water at 90°C for 5 minutes, then clean water at room temperature for 5 minutes, and then dry the steel wire in an oven at 125°C;

[0031] (4) After mixing xylene 35Kg...

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...
