Problems solved by technology

[0003] Most of the existing film materials are made of PVC film, but the scratch resistance of this type of film is poor. Damaged, the damaged film not only cannot protect the above-mentioned door panels, partition walls, wardrobes, etc., but also seriously affects the aesthetics of the above-mentioned products, loses its decorative effect, and cannot meet the requirements of consumers; The surface of the PVC film is coated with a surface treatment agent to improve the scratch resistance and water resistance of the film, but the curing degree of the existing surface treatment agent on the surface of the PVC film is low, resulting in the scratch resistance and impact resistance of the PVC film. Sex, etc. are still not enough to meet the needs

Abstract

The invention relates to the technical field of a decorative film material, in particular to a highlight scratch resistance agent and a process for preparing a highlight scratch resistance transparent PVC (Poly Vinyl Chloride) thin film by applying the same. The highlight scratch resistance agent consists of the following components in part by weight: 95 to 105 parts of oil polyurethane, 15 to 25 parts of curing agent, 0.8 to 1.2 parts of drier, 0.1 to 1 part of smooth agent and 75 to 85 parts of organic solvent. The highlight scratch resistance agent disclosed by the invention has the characteristics of good toughness, high hardness, strong scratch resistance and high brightness; the process for preparing the highlight scratch resistance transparent PVC thin film by applying the highlight scratch resistance agent adopts a method of directly coating a highlight scratch resistance coating on a PVC thin film, adopts a simple preparation process, has high production efficiency, requires a small quantity of production equipment, can reduce cost and is beneficial to general popularization and application; and the prepared highlight scratch resistance transparent PVC thin film has the advantages of high hardness, good scratch resistance, flat surface, high brightness and stable quality.

Description

technical field [0001] The invention relates to the technical field of decorative film materials, in particular to a high-gloss anti-scratch agent and a process for preparing a high-gloss anti-scratch transparent PVC film using the same. Background technique [0002] With the development of the economy and the improvement of people's living standards, people have higher and higher requirements for building materials and furniture such as interior door panels, partition walls, and wardrobes. Damaged by various mechanical forces such as collisions, depressions, and scratches. In recent years, the practice of attaching various membrane materials on the surface of building material panels has gradually emerged in the above-mentioned industries. It can not only protect the surface of the above-mentioned building material panels For protection, but also to achieve a good decorative effect. [0003] Most of the existing film materials are made of PVC film, but the scratch resistan...
