Abstract

The invention relates to a glue-breaking-resistant paint surface protecting cover and a preparation method thereof. The glue-breaking-resistant paint surface protecting cover comprises a polyurethane film, acrylic glue and release paper, wherein acrylic glue is breaking-resisting pressure-sensitive glue and prepared by using acrylic polytetrahydrofuran ester as a functional monomer and then copolymerizing with a soft monomer and a hard monomer and can resist stretching breaking. The glue-breaking resistant paint surface protecting cover can be applied well to the field of automobile pad pasting.

Description

technical field [0001] The invention relates to a paint surface protection film and a preparation method thereof, in particular to an anti-glue break paint surface protection film and a preparation method thereof. Background technique [0002] Since the birth of automobiles, human pursuit of automobile maintenance has never stopped. In order to keep the car as bright as new, people have thought of many ways, and waxing, which improves the brightness of the paint surface and reduces the damage of the paint surface, was born. In order to pursue a longer-term and effective protection effect, there has been the emergence of sealing glaze and coating technology. But with the development of science and technology, we have more and more requirements for car body maintenance, which should be simpler, more practical, and more fashionable, so the body paint film was born along with the trend. [0003] Pressure-sensitive adhesive is a type of adhesive that is sensitive to pressure. I...
