Abstract

The invention relates to a semi-rigid PVC (polyvinyl chloride) decorative membrane. The semi-rigid PVC decorative membrane comprises the following main raw materials in parts by weight: 100 parts of PVC resin powder, 18-23 parts of plasticizer, 3-5 parts of stabilizer, 25-35 parts of calcium carbonate, 4-6 parts of flame retardant, 6-9 parts of titanium white, 2-4 parts of soybean oil and 0.1-0.3 part of mold preventive; and the semi-rigid PVC decorative membrane is prepared through a calendering stage and an intaglio printing stage. The product provided by the invention is thin and semi-rigid, can not bubble in case of being laminated with glass and other materials, and can prevent broken glass from splashing and falling when the glass is broken; the addition of the flame retardant and the mold preventive endows the product with high-efficiency flame-retardant and mold-resistant properties, and the flame-retardant property and the mold-resistant property can be respectively up to B1 level and 0 level; and the product has long color retention time and long service life, and can soften bright light, partition space, enhance privacy and create a mild atmosphere.

Description

technical field [0001] The invention belongs to the field of decorative materials, and in particular relates to an ultra-thin semi-rigid PVC decorative film for laminating glass and other materials.

AI Technical Summary

Problems solved by technology

[0005] 1. The thickness of the product is high, resulting in high production costs, and more adhesives are required for bonding with glass and other materials; in addition, after the high-thickness PVC film is bonded to glass, the film and glass will be delaminated visually. It affects the aesthetics and further affects the practicability of the product;

[0006] 2. The product is too soft or too rigid. For products that are too soft, foaming is prone to occur when they are bonded to glass and other materials, and the bonding is difficult and costly. For products that are too rigid, printing is very difficult. Generally, the printing step cannot be carried out, which affects the aesthetics of the product, and cannot achieve the purpose of softening strong light, distinguishing space, improving privacy and creating a soft atmosphere;

[0007] 3. The flame retardancy and mildew resistance of the product are relatively low. Generally, the flame retardancy level of this type of decorative film is generally at B2 level, and the mildew resistance level is generally at level 1. Flame resistance and mildew resistance are related to everyone's life and health. further improvement;

[0008] 4. The color retention time of the printed pattern of the product is short, which affects the service life of the product
