Abstract

The invention relates to a novel casting rust-preventing cover layer belonging to the field of packaging materials. The novel casting rust-preventing cover layer comprises 15-75 parts of polyethylene, 15-75 parts of polypropylene, 3-5 parts of dispersing agent, 2-5 parts of smoothing agent and 5-10 parts of rust preventing master batch, wherein the rust preventing master batch comprises at least one of sebacate, molybdate, carboxylate, phytate and salicylhydroxamic acid. The novel casting rust-preventing cover layer has high flexibility and strength, and can be well pasted on the surface of a metal product. The invention also relates to a preparation method of the novel casting rust-preventing cover layer. The preparation method comprises the following steps: uniformly mixing the polyethylene, polypropylene and rust preventing master batch to obtain a base material; adding the dispersing agent and smoothing agent in the base material, and uniformly stirring to obtain a mixture; and putting the mixture into an extruder, extruding, and cooling to obtain the novel casting rust-preventing cover layer, wherein the temperature in the extruder is 120-190 DEG C, and the temperature at an extrusion die head of the extruder is 190-280 DEG C.

Description

technical field [0001] The invention relates to the field of packaging materials, and in particular to a novel cast anti-rust covering layer and a preparation method thereof. Background technique [0002] Metal corrosion has always been a major problem that has plagued the metal production and use industry. The direct loss caused by metal corrosion accounts for about 2%-4% of the gross national product every year. In order to reduce the loss, people use various methods to protect metal products. At present, the commonly used method is to coat the surface of metal products with anti-rust oil or anti-rust paint. Although anti-rust oil and anti-rust paint can protect metal products from corrosion damage to a certain extent, anti-rust oil and anti-rust paint The coating and maintenance of the paint are very inconvenient, and the components in the anti-rust oil and anti-rust paint are easy to endanger the environment and human health, and the use is greatly restricted.
