Preparation method of ultra-high-viscosity automotive carpet protective film

Abstract

The invention relates to the technical field of carpet protective films, and discloses a preparation method of an ultra-high-viscosity automotive carpet protective film. The ultra-high-viscosity automotive carpet protective film comprises a base material and an adhesive, wherein the base material comprises the following raw materials in percentage by weight: 10 to 30% of low-density polyethylene,20 to 40% of linear low-density polyethylene and 30 to 60% of metallocene polyethylene. The adhesive is prepared from the following raw materials in percentage by weight: 2 to 4% of acrylic acid, 25%of butyl acrylate, 50% of 2-ethylhexyl acrylate, 11% of vinyl acetate, 5% of methyl methacrylate and 2 to 5% of hydroxyethyl acrylate. The carpet protective film prepared in the invention has extremely strong puncture resistance, can be better attached to the surface of a carpet, has dustproof and antifouling effects and high cohesion strength, maintains high adhesive force, hardly leaves adhesive, is convenient to unwind and improved in use convenience, and has wide market prospects.

Description

technical field [0001] The invention relates to the technical field of carpet protective films, in particular to a method for preparing an extra-high-viscosity automotive carpet protective film. Background technique [0002] In the production process and delivery process of automobiles, carpets are often used for dust and pollution protection. Carpet protective films are often laid on the carpets, which protect the carpets on the one hand and facilitate the adhesion of dust on the carpets on the other hand. Then, it is widely used. [0003] At present, most of the conventional carpet protective films are used, and there are many shortcomings: 1. The viscosity of the protective film produced by domestic protective film manufacturers is difficult to exceed the peel strength of 7N / 25mm. Due to the limitation of the rough surface of the car carpet, the adhesion is relatively weak. Poor, easy to cause falling, unable to play the role of dust and pollution prevention; 2. Ordinary...

[0003] At present, most of the conventional carpet protective films are used, and there are many shortcomings: 1. The viscosity of the protective film produced by domestic protective film manufacturers is difficult to exceed the peel strength of 7N / 25mm. Due to the limitation of the rough surface of the car carpet, the adhesion is relatively weak. Poor, easy to cause falling, unable to play the role of dust and pollution prevention; 2. Ordinary carpet protective film is easy to react with the chemical fiber on the surface of the carpet, and the cohesion of the adhesive is not enough, often producing residual glue, which leads to pollution on the surface of the car carpet; 3. Ordinary protection It is difficult to unwind the film, and the end surface of the finished protective film overflows with glue, which is extremely inconvenient to use
