Preparation of degradable gasification anti-rust film

Abstract

The invention relates to a preparation method of degradable vaporability antirust film which can prevent metal corrosion. Mixed raw material is prepared by that sodium benzoate, dextrin, benzotriazoleand colloid with the weight proportion of 8:8:6:1 are put into a mixing machine to be stirred and mixed for 20 minutes; the mixed raw material is crushed to be 350 meshes so as to obtain the grain mixed raw material; furthermore, the grain mixed raw material, nanometre copper powders, polyvinyl ester and zinc stearate with the weight proportion of 23:5:7:3 are put into the mixing machine to be stirred and mixed for 30 minutes so as to obtain the secondary mixed raw material; low-density polyethylene of 130-140 times (by weight) is put into the secondary mixed raw material, both of which are mixed for 30 minutes under the temperature control condition to obtain a PE mixture; finally, the PE mixture is put into a film blower to blow out the degradable vaporability antirust film with the thickness of 0.1mm by controlling the film-blowing temperature; the preparation method of the invention has the advantages of simple preparation technology, easy condition control, easily-gained raw material, low preparation cost and good product quality.

Description

Technical field: [0001] The invention relates to a preparation method of a degradable gasification rust preventive film which can prevent metal corrosion by adding a degradable function to the gasification rust preventive film. Background technique: [0002] Because of its large molecular weight, most polyethylene products are not easy to decompose after being discarded, so they will cause various environmental pollution problems, or dioxins (DIOXIN) emitted during burning will produce carcinogens, which are harmful to the air and the environment. , are harmful to the human body. Therefore, in order to remove various pollutants, the disposal cost is very expensive. Moreover, when using chemicals for anti-corrosion materials, most of them either use chemicals that are harmful to the environment such as chromium and phosphorus, or use pollutants such as amines (Amin) and nitrites that are harmful to the human body. In view of this situation, it is very urgent to develop new ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcoming that prior art exists, seeks to design the preparation process of the degradable gasification anti-rust film that can prevent metal corrosion, and when this anti-rust film degrades within a certain period of time, it will not cause Environmental pollution; the invention adds metallic new materials to make the product biodegradable, and also has the anti-corrosion function for iron and non-ferrous metals. No matter how bad the use conditions are, it will also produce balanced anti-corrosion performance, and at the same time solves the problem of waste disposal. Burning or burying in the ground creates problems of polluting the environment
