A transparency modifier for vapor phase antirust film

Abstract

The invention provides a transparency modifier for a vapor phase antirust film, belonging to the technical field of antirust film preparation. The transparency modifier of the vapor phase antirust film of the present invention consists of FLAMESTAB NOR 116, 2-(2'-hydroxyl-5'-methylphenyl) benzotriazole, peroxide cross-linked polyethylene, copolymer modifier composition. Under the joint action of FLAMESTAB NOR 116 and 2‑(2′‑hydroxy‑5′‑methylphenyl) benzotriazole, the antirust additives in the gas phase antirust film can be used in the blown film process and later The structure is stable and no colored substances are generated; under the joint action of peroxide crosslinked polyethylene and copolymerization modifier, the polyethylene resin maintains its crystallinity and regularity during the film blowing process, thereby maintaining its own Higher transparency, thereby improving the transparency of the vapor phase antirust film.

Description

technical field [0001] The invention relates to the technical field of antirust film preparation, in particular to a transparency modifier for gas phase antirust film. Background technique [0002] Vapor phase antirust film is a metal antirust plastic film that has gradually emerged in recent years. The vapor phase corrosion inhibitor contained in it can automatically volatilize to the metal surface, and the vapor phase corrosion inhibitor forms a protective layer on the metal surface to inhibit corrosion. The role of metal corrosion. Vapor phase antirust film has the characteristics of long antirust period, easy operation, wide application scenarios and low cost. It is a metal protective packaging material that has developed rapidly in recent years and is of great significance to the metal processing industry. [0003] At present, vapor phase anti-rust films are all made of polyethylene resin as the base material, and volatile chemical substances are added to it. Since mos...

Problems solved by technology

The anti-rust core components added to the existing gas-phase anti-rust film, there are two situations that will cause the color change of the anti-rust film. One is that some components are affected by ultraviolet rays in natural light, and the structure gradually changes, and then presents a certain color ; Second, due to the influence of high temperature in the processing process, the original colorless component structure changes, resulting in abnormal color (light yellow or pink) of the anti-rust film, and it may be uneven, which reduces the appearance quality of the product

The third is that during the processing, under the action of high temperature, the degree of polymerization and crystallinity of the polyethylene polymer chain decreases, resulting in a decrease in transparency

[0005] However, as the application of gas-phase anti-rust film becomes wider and wider, users put forward higher requirements for transparency. Traditional gas-phase anti-rust film cannot meet the requirements, but changing the composition of anti-rust additives requires a large number of formula screening tests and investment in research and development. The cost is very high, so there is a need for users and manufacturers to improve the transparency of the vapor phase antirust film
