Problems solved by technology

Since these materials have a relatively low glass transition temperature and molecular weight, the temperature resistance is greatly reduced. Therefore, it is difficult to peel off the surface of the substrate after the process protection is completed, and the adhesive resin is often transferred and remains on the protected body after peeling off. On the surface of the surface, alth

Abstract

The invention discloses a manufacturing method of a heat-shrinkable auto-adhesive vacuum plating protective film. The manufacturing method comprises the following steps: (1) firstly, synthesizing polyvinyl polyacrylate; (2) then, performing melt blending on the polyvinyl polyacrylate, polyethylene resin, a first initiator and an antioxidant according to a weight proportion, extruding and granulating, and finally performing extrusion film blowing and UV curing to obtain the heat-shrinkable auto-adhesive vacuum plating protective film. The manufactured protective film wraps a local part, required to be protected, of a vacuum plating component in a heat shrinkage way; in a vacuum plating process, the surface of the film does not crease and deform, the adhesion force is stable, the attachment property is good, the re-peeling performance is excellent, the phenomenon of adhesive residue is avoided, and the barrier and mechanical properties are excellent; the heat-shrinkable auto-adhesive vacuum plating protective film is an excellent vacuum plating protective film material which is non-toxic, environmentally-friendly, safe and practical.

Description

technical field [0001] The invention relates to the field of protective films, in particular to a method for manufacturing a heat-shrinkable self-adhesive vacuum plating protective film. Background technique [0002] Vacuum coating protective film is a modified film material, which has the characteristics of self-adhesive and thermal shrinkage. It is actually a special pressure-sensitive adhesive film, which is mainly composed of substrate and pressure-sensitive materials. Compared with surface protection coatings, it has the advantages of convenient use, low price, and reliable effect, and has attracted much attention in the field of material surface protection. Since polyethylene material is cheap and its viscosity can be adjusted in a wide range according to different application requirements, the current substrate layer mainly uses polyethylene as raw material and is prepared by extrusion molding, injection molding, extrusion blown film molding and other methods. Howeve...
