Embodiment 1

[0013] An antibacterial plastic, comprising the following components in parts by weight: 100 parts of polyethylene terephthalate, 0.4 parts of tributyl phosphite, 1 part of sorbitol benzaldehyde, and 0.2 parts of silver-loaded zirconium phosphate.

Embodiment 2

[0015] An antibacterial plastic, comprising the following components in parts by weight: 100 parts of polyethylene terephthalate, 0.6 part of tributyl phosphite, 0.5 part of sorbitol benzaldehyde, and 0.5 part of silver-loaded zirconium phosphate.

[0016] The number average molecular weight of the polyethylene terephthalate is 30000 g / mol.

[0017] The intrinsic viscosity of the polyethylene terephthalate was 0.7 dl / g.

[0018] The antibacterial properties of the antibacterial plastics prepared in Examples 1 to 2 of the present invention are shown in Table 1.

Abstract

An antibiotic plastic comprises, by weight, 100 parts of polyethylene glycol terephthalate, 0.4-0.6 parts of tributyl phosphite, 0.5-1 part of dibenzylidene sorbitol and 0.1-0.5 parts of silver-supported zirconium phosphate. The silver-supported zirconium phosphate is adopted as a bactericide, and dibenzylidene sorbitol is adopted as a nucleating agent, so polyethylene glycol terephthalate has a good antibiosis effect under high transparency.

Description

technical field [0001] The invention relates to an antibacterial plastic, in particular to a PET antibacterial plastic. 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), and polypropylene (PP) as raw materials. After adding corresponding organic solvents, after high temperature heating, they are blown through plastic molds. , 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] Because the bottle will be in direct contact with hands, it is easy to breed bacteria. Contents of the ...
