Abstract

A polypropylene BOPP color modifier is prepared from the following raw materials in parts by weight: 35-55 parts of modified polyvinyl chloride resin, 5-10 parts of high-performance accelerator, 15-20parts of absolute ethanol, 3-8 parts of octadecylamine, 5-10 parts of hydrogen peroxide, 1-3 parts of tallow diamine dioleates, 0.5-1.5 part of polyphenyl phosphite, 5-8 parts of triethylene glycol diheptanoate. The color modifier prepared by the modified PVC resin has excellent stability, good gloss and transparency on the one hand, and will not affect the polypropylene BOPP on the other hand. The content of urethane bond formed by the reaction of cyanate ester group in the accelerator and hydroxyl group increases, the molecular bonding force formed on the surface of the polypropylene BOPP increases, thereby enhancing the adhesion. Therefore, the color modifier prepared by the high-performance accelerator has excellent adhesion to the polypropylene BOPP, and does not affect the transparency and brightness of the color modifier.

Description

technical field [0001] The invention relates to a color-changing agent, in particular to a polypropylene BOPP color-changing agent. Background technique [0002] Biaxially oriented polypropylene film (BOPP) is generally a multi-layer co-extruded film, which is obtained by co-extruding polypropylene particles into a sheet, and then stretching in both vertical and horizontal directions. Due to the orientation of the stretched molecules, this film has good physical stability, mechanical strength, air tightness, high transparency and gloss, and is tough and wear-resistant. It is the most widely used printing film at present, and the general use thickness is 20- 40μm, the most widely used is 20μm. [0003] The main disadvantage of biaxially oriented polypropylene film is poor heat sealability, so it is generally used as the outer film of composite film. For example, after compounding with polyethylene film, the moisture resistance, transparency, strength, stiffness and printabil...
