Abstract

The invention relates to a matte PVC decorative film capable of reducing the surface brightness of a product. The matte PVC decorative film is prepared from the following components in parts by weight: 100 to 120 parts of PVC resin powder, 15 to 100 parts of matting powder, 8 to 12 parts of calcium powder, 3 to 5 parts of feeling agent, 0.3 to 0.5 part of titanium dioxide, 20 to 30 parts of plasticizer, 3 to 3.5 parts of barium-zinc stabilizing agent, 0.2 to 0.4 part of internal lubricant, 2 to 4 parts of processing aid, and 1 to 2 parts of stain resistant aid. According to a standard GB / T17657-2013, common contaminants (acetone and black coffee) are used to carry out a stain resistance test; the test result shows that the provided matte PVC decorative film has a better stain resistant performance, compared with a conventional matte PVC decorative film; and the problem that the stain resistant performance of the conventional PVC decorative film is solved. At the same time, the matte PVC decorative film has the advantages of excellent matte property, scratch resistance, stain resistance, easiness for scrubbing, and soft feeling, and can be well matched with other decorative materials.

Description

technical field [0001] The invention belongs to the technical field of polymer compounds, and in particular relates to a matte PVC decorative film that can reduce the surface brightness of products. Background technique [0002] Matte PVC decorative sheet uses polyvinyl chloride resin as the main raw material, adds matte PVC auxiliary materials, and adopts PVC calendering process to form and decorate the rear part with monochrome fabrics, one or two layers of decorative films in hard middle materials Fitted. Matte decorative sheets have excellent matte properties and are widely used in home furnishing, decoration, home appliances, furniture, automotive interiors and other products. [0003] The existing matte PVC decorative film that can reduce the surface brightness of the product has insufficient properties such as scratch resistance, stain resistance and easy scrubbing, and soft touch, and is easily damaged during use, affecting appearance and use. Contents of the inve...
