Graphene anti-corrosion stretch film and preparation method thereof

Abstract

The invention discloses a graphene anti-corrosion stretch film. The graphene anti-corrosion stretch film is composed of the following raw materials in parts by weight: 17-20 parts of graphene, 1-2 parts of lauryl dimethyl amine oxide, 0.7-1 part of glycolic acid, 6-8 parts of allylpolyethyleneglycol, 110-120 parts of LLDPE, 4-5 parts of anti-corrosion polymer, 2-3 parts of aluminum dihydrogen phosphate, and 3-4 parts of epoxidized triglyceride. According to the graphene anti-corrosion stretch film and the preparation method thereof, not only is the graphene effectively organized, but also anti-corrosion performance is imparted to the grapheme, so that when the graphene is mixed with the LLDPE, the compatibility of the graphene with the LLDPE can be improved, thereby improving mechanical stability and anti-corrosion performance of a finished stretch film.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a graphene anti-corrosion stretch film and a preparation method thereof. Background technique [0002] Stretch film, also known as stretch film and heat shrinkable film, was the first in China to produce PVC stretch film with PVC as the base material and DOA as the plasticizer and self-adhesive function. Due to environmental protection issues, high cost (compared to PE, relatively large proportion, small unit packaging area), poor stretchability and other reasons, when PE stretch film was produced in China from 1994 to 1995, it was gradually eliminated. PE stretch film first uses EVA as self-adhesive material, but its cost is high and tasteful. Later, PIB and VLDPE are used as self-adhesive material. Now the base material is mainly LLDPE, and the stretch film can form a very light around the product. Protective appearance, so as to achieve the purpose of dust-proof, oil-proo...

Problems solved by technology

[0003] With the continuous development of society, more and more attention has been paid to the research of new materials. Currently, the stretch film on the market has only one function. It affects the conductive work of the coating material. Therefore, the present invention studies a special stretch film with conductivity. When the conductive work is required, the conductive work of the coating material can be carried out without removing the wrap film;

[0004] At the same time, in order to reduce the production cost, the currently commercially available stretch film has low tensile strength and is easy to break, and the inorganic fillers that enhance the mechanical strength are added to the stretch film, which has poor compatibility with the film, resulting in poor stability of the film.
