Abstract

The invention relates to a preparation method of bottle production resin. The bottle production resin comprises, by weight, 60 parts of PET, 40 parts of PC, 0.4-0.6 parts of tributyl phosphite, 2-5 parts of polypropylene grafted maleic anhydride and 0.5-1 part of dibenzylidene sorbitol. Small amounts of tributyl phosphite and dibenzylidene sorbitol make the PET and the PC be uniformly mixed, crystals be pure and the transparency be increased.

Description

technical field [0001] The invention relates to a bottle-making resin, in particular to a method for preparing an alloy of PET and PC. Background technique [0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP) and other materials as raw materials. After adding corresponding organic solvents, after high temperature heating, they pass through plastic molds. Blow molded, extrusion blown, or injection molded plastic containers. It is mainly used for liquid or solid disposable plastic packaging containers for beverages, food, pickles, honey, dried fruits, edible oil, agricultural and veterinary drugs, etc. Plastic bottles have the characteristics of unbreakable, low cost, high transparency, and food-grade raw materials. [0003] The existing PET and PC alloys have relatively low transparency. C...
