Problems solved by technology

[0003] The adhesion between the PE protective film and the protected product is not firm, and it may fall off during transportation and use. It may be that the pressure-sensitive adhesive used in the production of the protective film product is not viscous enough, or when pasting, the external tension is greater than the internal tension. Stress, causing the protective mold to shrink, causing the corners to warp

Abstract

The invention belongs to the technical field of PE protective films, and particularly relates to degumming-proof PE protective film glue and a preparation method thereof. The degumming-proof PE protective film glue comprises the following components in parts by weight: 60-70 parts of propyl acrylate, 15-30 parts of butyl acrylate, 10-20 parts of ethyl methacrylate, 10-20 parts of butyl methacrylate, 1-3 parts of nonylphenol polyoxyethylene ether and 0.5-1 part of octylphenol polyoxyethylene ether. In the preparation process of the glue, glass fiber powder is added, glass fibers are fully blended into pressure-sensitive adhesives in the preparation process, so that the insides of the pressure-sensitive adhesives are pulled towards one another, in an adhesion process, deformation amounts ofa protective film and the pressure-sensitive adhesives can be controlled, deformation difference between the protective film and the pressure-sensitive adhesives can be reduced, thus, internal stressis relieved, the protective film cannot be easily lifted on the surface of the product, moreover, by mixing the propyl acrylate, the butyl acrylate and the ethyl methacrylate, the stiffness and elasticity of a copolymer are improved, the cohesion is increased, and the pressure-sensitive adhesives which are not easy to degum are formed.

Description

technical field [0001] The invention belongs to the technical field of PE protective films, and in particular relates to an anti-degumming PE protective film glue and a preparation method thereof. Background technique [0002] PE protective film is the simplest polymer organic compound and the most widely used polymer material in the world today. PE protective film is based on special polyethylene (PE) plastic film, which is divided into high-density polyethylene according to different densities. Protective film, medium density polyethylene and low density polyethylene. [0003] The adhesion between the PE protective film and the protected product is not firm, and it may fall off during transportation and use. It may be that the pressure-sensitive adhesive used in the production of the protective film product is not viscous enough, or when pasting, the external tension is greater than the internal tension. Stress, causing the protective mold to shrink, causing the corners t...
