[0038] The raw material of the core layer is composed of mLLDPE, LLDPE, and LDPE in a weight ratio of 15:35:50, that is, 15 parts of mLLDPE, 35 parts of LLDPE, and 50 parts of LDPE.

[0039] The raw material of the outer adhesive layer is composed of POE, SEBS, hydrogenated C5 resin, and hydrogenated C9 resin in a weight ratio of 15:45:15:25, and then blended and granulated after uniform mixing, that is, 15 parts of POE, 45 parts of SEBS, 15 parts of hydrogenated C5 resin, 25 parts hydrogenated C9 resin.

[0040] After the materials of each layer are mixed evenly, they are sent to a three-layer co-extrusion film blowing machine to extrude and blow the film to prepare a PE self-adhesive stainless steel protective...

Embodiment 3

[0042] Described its inner surface layer raw material is made up of dendritic toughening agent, mica particle, LLDPE and LDPE that weight ratio is 15:15:30:40, namely 15 parts of dendritic toughening agent, 15 parts of mica particle, 30 parts LLDPE and 30 parts LDPE.

[0043] The core material is composed of mLLDPE, LLDPE and LDPE in a weight ratio of 20:30:50, that is, 20 parts of mLLDPE, 30 parts of LLDPE and 50 parts of LDPE.

[0044] The raw material of the outer adhesive layer is made of POE, SEBS, and hydrogenated C9 resin in a weight ratio of 25:40:35, and then blended and granulated, that is, 25 parts of POE, 40 parts of SEBS, and 35 parts of hydrogenated C9 resin.

[0045] After the materials of each layer are mixed evenly, they are sent to a three-layer co-extrusion film blowing machine to extrude and blow the film to prepare a deep-drawing-resistant PE self-adhesive stainless steel protective film.

Abstract

The invention belongs to the technical field of polymer material film preparation and discloses a deep drawing-resistant PE self-adhesive stainless steel protective film, which mainly solves the technical problem that the existing PE stainless steel protective film is easily broken during the deep drawing process. The key points of its technical scheme are: PE self-adhesive protective film is produced by three-layer co-extruded blown film, the inner surface layer is composed of dendritic toughener, mica particles, LLDPE and LDPE; the core layer is composed of mLLDPE, LLDPE, LDPE; The adhesive layer is composed of POE, SEBS, hydrogenated C5 resin or hydrogenated C9 resin or hydrogenated C5-C9 copolymer resin or blended granules of two kinds. The preparation process is to firstly mix the outer sticky layer materials uniformly according to the weight ratio, then blend and granulate, and then send the materials of the inner surface layer and the core layer which are uniformly mixed according to the weight ratio to a three-layer co-extrusion blown film machine for extrusion blowing. film, cooling and coiling to obtain the product.

Description

technical field [0001] The invention belongs to the technical field of polymer material film preparation, and in particular relates to a deep drawing-resistant PE self-adhesive stainless steel protective film, which solves the problem that the existing PE stainless steel protective film is easily broken during the deep drawing process. Background technique [0002] The traditional production method of PE stainless steel protective film is to blow the PE film on a three-layer co-extrusion blown film machine first, then corona the inner layer of the PE film to polarize the outer surface of the film, and then coat such as polyester Acrylic, modified natural rubber and other types of pressure sensitive adhesives. The disadvantages of the products produced by this traditional method are not only complex production process, but also need high temperature drying, high energy consumption; and because the coated adhesive needs to use organic solvents, which brings environmental pollu...
