Problems solved by technology

[0002] At present, the most commonly used anti-corrosion method in industry is to coat the metal surface with anti-rust oil, but this method will lose efficacy due to oxidation of the anti-rust oil itself, and it is time-consuming and labor-intensive to remove the protective layer, which is neither hygienic nor Safety
The use of desiccant to prevent rust is low in cost, simple in operation, safe and environmentally friendly, easy to remove protective packaging, but the effective time is short, and it is greatly affected by the ambient temperature
As for the packaging and processing of metal materials with special dehumidification equipment, although the anti-rust effect is good, the cost is high, time-consuming and labor-intensive, and the operation is complicated

Abstract

The invention discloses a composition for making a polyvinyl chloride thermal contraction vapor phase antirust film. The composition comprises a polyvinyl chloride resin, a plasticizer, a stabilizer, a secondary plasticizer, an impact modifier, a polyethylene resin, cyclohexylamine phosphate, fatty acid dicyclohexylamine, a morpholine derivative and a lubricant. The polyvinyl chloride thermal contraction antirust film is produced by utilizing the composition used for making the polyvinyl chloride thermal contraction antirust film and containing a vapor phase rust inhibitor through a routine production method of the polyvinyl chloride thermal contraction antirust film in order to realize convenient production and vapor phase antirust requirements; and the vapor phase rust inhibitor adopted in the invention does not like traditional nitrous acid vapor phase rust inhibitors, and is in favor of realizing environmental protection and the health of human bodies.

Description

technical field [0001] The invention relates to the field of gas-phase anti-rust, in particular to a composition for preparing polyvinyl chloride heat-shrinkable gas-phase anti-rust film. Background technique [0002] At present, the most commonly used anti-corrosion method in industry is to coat the metal surface with anti-rust oil, but this method will lose efficacy due to oxidation of the anti-rust oil itself, and it is time-consuming and labor-intensive to remove the protective layer, which is neither hygienic nor Safety. The use of desiccant for anti-rust has low cost, simple operation, safety and environmental protection, and easy removal of protective packaging, but the effective time is short, and it is greatly affected by the ambient temperature. As for the packaging and processing of metal materials with special dehumidification equipment, although the anti-rust effect is good, the cost is high, time-consuming and labor-intensive, and the operation is complicated....
