Semi-rigid polyvinyl chloride portrait calendered film

Abstract

The invention discloses a semi-rigid polyvinyl chloride portrait calendered film. The semi-rigid polyvinyl chloride portrait calendered film comprises the following components in parts by weight: 60-70 parts of polyvinyl chloride resin, 15-20 parts of an acrylonitrile-butadiene-styrol copolymer, 14-20 parts of corundum fine powder, 9-13 parts of melamine cyanurate, 23-29 parts of glass fiber, 2-3 parts of gelatin, 25-35 parts of octyltin mercaptide, 18-28 parts of silicon carbide powder, 14-20 parts of magnesium hypophosphite, 3-6 parts of di-sec-butyl-p-phenylene, 3-7 parts of meerschaum, 9-17 parts of sodium salicylate, 3-8 parts of titanium dioxide, 10-20 parts of benzoin ethyl ether, 1.2-1.4 parts of tetrabutyl titanate, 12-14 parts of ramie bone, 13-15 parts of acetyl tributyl citrate, 2-3 parts of diethylene glycol monoethyl ether acetate, and 3-4 parts of glycerin. The calendered film has the advantages of high strength, good temperature toleration, good covering rate, and good ink absorbency, can replace the traditional portrait paper, and can make up the defect of nano calcium by adding corundum fine powder and silicon carbide powder.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a semi-rigid polyvinyl chloride photo calendering film. Background technique [0002] In recent years, vigorously developing high value-added functional film packaging materials has become the development trend of plastic packaging materials in various countries in the world. Functional films usually have high technical content, but also have good economic benefits and strong market competitiveness, so they have attracted people's attention. At present, functional packaging films that have been industrialized and are of great significance in the packaging field include barrier packaging films, shrinkable packaging films, surface protection films, easy-to-open films, antistatic films, antirust films, antibacterial films, and degradable films. , Functional packaging film is an important variety of packaging materials, often an indispensable material for some specific packaging, ...

Problems solved by technology

[0003] At present, according to the national standard GB / T3830-2008, the main raw materials for the production of semi-rigid polyvinyl chloride calendered film are polyvinyl chloride resin, plasticizer, heat stabilizer, and inorganic fillers. The inorganic fillers generally use nano-scale calcium carbonate and a A mixture of superfine heavy calcium carbonate; using nano-scale calcium carbonate to fill the modified semi-rigid polyvinyl chloride calendered film has a certain enhancement effect on the brightness of the smooth polyvinyl chloride calendered film; but the use of nano-scale calcium carbonate Calcium-filled modified semi-rigid PVC calendered film has disadvantages such as poor weather resistance, low strength, and low temperature resistance
