Problems solved by technology

However, ordinary pearl cotton products have no anti-rust function. During the transportation of metals, especially the transportation of finished parts, it is necessary to use anti-rust paper, anti-rust oil or anti-rust film to prevent rust, which not only increases logistics In the process, but also a waste of manpower and material resources

Abstract

The invention relates to a gas-resistance antirust pearl cotton and a preparation method thereof, belonging to the technical field of polymer materials. The pearl cotton includes the following raw materials in parts by weight: 80-100 parts of LDPE resin particles, 0.5-1 part of modified attapulgite, 0.5-1 part of talcum powder, 0.2-0.4 parts of foaming agent, and 0.002 parts of color masterbatch. ~0.005 parts, 0.2~0.5 parts of monoglyceride, 8~10 parts of nitrogen flame retardant, 6~12 parts of 4-(N,N-di-n-butyl)-aminomethylmorpholine, 1~ 2 servings. On the basis of maintaining the advantages of traditional pearl cotton, the product of the present invention adds a nitrogen-based flame retardant, so that the product of the present invention has a good flame-retardant effect. Morpholine is a gas-phase corrosion inhibitor, which has a good gas-phase anti-rust function, so that the purpose of anti-rust can be achieved without additional anti-rust packaging materials during metal transportation, saving manpower and material resources.

Description

technical field [0001] The invention belongs to the technical field of macromolecule materials, and in particular relates to a gas-resistance anti-rust pearl cotton and a preparation method thereof. Background technique [0002] The problem of metal corrosion pervades all walks of life in the national economy, and it will greatly damage the performance and commercial value of metal products. [0003] At present, vapor phase antirust packaging material is a metal protective packaging material that has developed rapidly in recent years. It is a new generation of innovative high-tech products based on the combination of polymer materials and VCI vapor phase antirust technology. After using this material to package and seal the anti-rust item, the VCI contained in the material begins to sublimate and volatilize the anti-rust gas factor, which diffuses and penetrates to the surface of the anti-rust item and adsorbs on it, forming a dense protective film layer with a thickness of ...
