VCI degradable antirust film

Abstract

The invention provides a VCI degradable antirust film. The VCI degradable antirust film is composed of an outer layer and an inner layer, wherein the outer layer is prepared from the following raw materials of, by weight, 100-150 parts of polyvinyl alcohol, 50-90 parts of starch, 20-40 parts of photosensitizer and 20-50 parts of biodegradable agents; and the inner layer is a mixed layer of volatile corrosion inhibitors and is prepared from the following raw materials of, by weight, 100-120 parts of PP resin, 10-30 parts of ammonium chromate, 15-25 parts of benzoic acid monoethanolamine, 20-40parts of o-nitrophenol dicyclohexylamine, 10-20 parts of cyclohexylamine, 30-50 parts of calcium carbonate, 10-20 parts of talcum powder, 15-25 parts of plasticizers, 5-15 parts of sodium benzoate, 2-6 parts of dextrins, 3-9 parts of benzotriazole, 3-9 parts of sodium molybdate, 3-8 parts of hydroxyethyl cellulose, 4-10 parts of zinc stearate and 4-10 parts of polyethylene waxes. The VCI degradable antirust film achieves an ideal degradation effect, breaks through the limitation of rust prevention at the same time, and has wide application, a simple preparation method and simple operation.

Description

technical field [0001] The invention relates to the technical field of degradable materials, in particular to a VIC degradable antirust film. Background technique [0002] The overall scale of China's environmental protection industry is relatively small, and its boundaries and connotations are still expanding and enriching. All kinds of plastic products have greatly enriched people's lives, but waste plastics decompose very slowly in nature, and it takes decades or even hundreds of years to completely decompose. Therefore, with the development of China's social economy and the adjustment of industrial structure, China's environmental protection The direct contribution of the industry to the national economy will change from small to large, and gradually become an industry that improves the quality of economic operation, promotes economic growth, and improves the level of economic technology. The direction of industrial connotation expansion will mainly focus on clean techn...

AI Technical Summary

Problems solved by technology

Tests have shown that most degradable plastics begin to become thinner, lose weight, and lose strength after being exposed to the general environment for 3 months, and gradually break into pieces

If these fragments are buried in garbage or soil, the degradation effect is not obvious

There are four shortcomings in the use of degradable plastics: one is to consume more food; the other is that the use of degradable plastic products still cannot completely eliminate "visual pollution"; "Potential hazards" fourth is the disadvantages of degradable plastics that are difficult to recycle due to special additives

However, the application range of the degradable anti-rust film developed or successfully developed is still relatively narrow, and it is still unable to replace popular plastics. Degradation anti-rust film to meet the needs of the modern market
