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, benzotriazole and 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 anti-rust film with a degradable function added on the basis of the gasification anti-rust film for preventing metal corrosion. Background technique: [0002] Most of the polyethylene products are not easy to decompose after being discarded because of their large molecular weight, 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 harmful to the environment such as chromium and phosphorus, or use pollutants harmful to the human body such as amines (Amin) and nitrite. It is very urgent to develop new products that are friendly to the envir...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcoming that prior art exists, seek to design a kind of preparation process of the degradable gasification antirust film that can prevent metal corrosion, and when this antirust film degrades within a certain period of time, it does not Causes environmental pollution; the invention adds metallic new materials to make the product biodegradable, and also has anti-corrosion functions for iron and non-ferrous metals, even if the use conditions are harsh, it will also produce balanced anti-corrosion properties, and at the same time solves the problem of waste disposal Sometimes burned or buried in the ground to cause environmental pollution problems
