Problems solved by technology

The coating method increases the process, and most of them use organic solvents, which is a waste of resources and unsafe, and friction resistance is often a problem
Inorganic matting agents or fillers are added to the formula, if the quantity is small, the effect is not good, if the quantity is large, the mechanical strength will be damaged, and there will be wear and tear on the equipment

Embodiment 1

[0027] A PVC matting film modified by matting resin is characterized in that: the PVC matting film comprises the following components, which consist of,

[0028] 70 parts by weight of polyvinyl chloride resin;

[0029] Matting resin (VinnolitC 100V) 30 parts by weight;

[0030] Bisphenol A antioxidant 0.4 parts by weight;

[0031] 0.5 parts by weight of UV-531 ultraviolet absorber;

[0032] Dioctyl phthalate 30PHR;

[0033] Epoxidized soybean oil 2PHR;

[0034] Barium zinc heat stabilizer 2.5PHR.

[0035] The processing process of the matting film modified by the matting resin in this example: After weighing each component, put the resin, stabilizer and plasticizer in the high-speed mixer at a low speed, and stir at a high speed at about 105°C to discharge the material, and then cold stir , and then to the middle barrel to the planetary extruder for thermal plasticization, and then fully mixed and exhausted in two open plastic mixers respectively, after being filtered by ...

Abstract

The invention relates to a matting resin modified polyvinyl chloride (PVC) matt film, belonging to the technical field of PVC matt films. The matting resin modified PVC matt film comprises the following components: 60 to 90 weight parts of polyvinyl chloride resin, 10 to 40 weight parts of matting resin (VinnolitC 100V), 20 to 50PHR of dioctyl phthalate, 2 to 10PHR of epoxy soybean oil, 2 to 5PHR of a thermal stabilizer, 0.3 to 0.5PHR of an antioxidant, and 0.1 to 1.0PHR of an ultraviolet absorbent. The modified matt film can achieve surface effects of anti-sticking, matting, grain forming and the like, has a good surface matting effect, has high adaptability to processing conditions, and has the advantages of good matting effect and the like in a broad plasticizing temperature range.

Description

technical field [0001] The invention belongs to the technical field of PVC matting film, in particular to a PVC matting film modified by matting resin. Background technique [0002] At present, among daily necessities and industrial products such as PVC artificial leather, floors, wallpapers, tarpaulins, and films, matt products are favored by many consumers. The general extinction methods include physical methods and chemical methods. [0003] Physical methods include release paper method, sandblasting embossing roller method, etc., which have been widely used. The matting effect is uniform and the processing procedure is relatively convenient. , their applications are limited. [0004] Chemical methods include coating matting coating or matting agent layer, adding inorganic matting agent or inorganic filler to the formula, adding PVC resin type matting agent to the formula, etc. The coating method increases the process, and most of them use organic solvents, which is a ...
