Embodiment 1

[0017] A antibacterial plastic, including the following weight components: 100 parts of polyzhexyl gemo glycol, 0.4 scent esters of phosphates, 1 part of sorge glycol -shrinking dilatedehyde, and 0.2 copies of silver phosphoric acid.

[0018] The preparation method of antibacterial plastic above, including the following steps:

[0019] A. Polyphyenate ethylene glycolin is drumped and dry for 2 hours at 120 ° C;

[0020] B. Add the polypholic glycolic glycol ester of the step A to the mixer. At the same time, the triatholes, pearl glycol -shrinking diodedehyde, and silver phosphate are added to the mixer at the same time.Mix mixing for 20 minutes to make the ultimate mixture.

[0021] C. Add the ultimate mixture of step B to the dual screw extrusion machine. The processing temperature of the 1 area of the double screw extrusion machine is 255 ° C, the processing temperature of the 260 ° C area in the 2 area is 260 ° C, and the processing temperature of the 3 area is 265 ° C.The pro...

Embodiment 2

[0023] A antibacterial plastic, including the following weight components: 100 parts of polyzhexyl gemo glycol, 0.6 scent of vilurticate, 0.5 parts of pearl alcohol shrinking dietary formaldehyde, and 0.5 parts of silver phosphate.

[0024] The average molecular weight of polypholic glycolitate is 30000g / mol.

[0025] The characteristic viscosity of polypholic acid ethylene glycol is 0.7DL / g.

[0026] A. Polyphyenate ethylene glycolin is drumped and dry for 2 hours at 120 ° C;

[0027] B. Add the polypholic glycolic glycol ester of the step A to the mixer. At the same time, the triatholes, pearl glycol -shrinking diodedehyde, and silver phosphate are added to the mixer at the same time.Mix mixing for 20 minutes to make the ultimate mixture.

[0028] C. Add the ultimate mixture of step B to the dual screw extrusion machine. The processing temperature of the 1 area of the double screw extrusion machine is 255 ° C, the processing temperature of the 260 ° C area in the 2 area is 260 °...

Abstract

The invention relates to a preparation method of an antibiotic plastic. The 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 involves a method of preparing a antibacterial plastic, especially a PET antibacterial plastic. Background technique [0002] The plastic bottle is mainly made of polyethylene or polypropylene and adds a variety of organic solvents.Plastic bottles are widely used in polyzhebenate glycol (PET), polyethylene (PE), polypropylene (PP) as raw materials. After adding corresponding organic solvents, after high temperature heating, plastic mold passes through plastic molds through plastic mold, Squeezing, or injection molding plastic container.It is mainly used for beverages, food, pickles, honey, dried fruits, dried fruits, edible oils, agricultural veterinary drugs and other solid plastic packaging containers.Plastic bottles have the characteristics of non -crushing, low cost, high transparency, and food -grade raw materials. [0003] Because the bottle is directly contacted with the hand, it is easy to breed bacteria. Invention content [0004] In...
