Embodiment 1

[0028] The PET composition used for packaging bottles, its components in parts by weight are: 50 parts of PET resin, 1.1 parts of stearic acid, 9 parts of TDBPPE, 3.5 parts of EPDM, 0.7 parts of ethylene bis stearamide, 1.5 parts of nano ATO, basalt 5 parts of fiber, 2 parts of methyl phenyl dimethyl silicone, 3.2 parts of maleic anhydride grafted SMA, 5.1 parts of epoxy resin, 7.7 parts of composite melanin capsule, 2 parts of nylon.

[0029] Its manufacturing method is as follows:

[0030] (1) Wash the black grape skins and dry them, crush them to obtain black grape skin powder, add the black grape skin powder to petroleum ether at a material-to-liquid ratio of 1:30, adjust the pH value to 5, and place in a 65°C water bath Extracted from the black grape skin for 2 hours, centrifuged at a speed of 3000 rpm, and dried the obtained filtrate in an oven at 65°C to obtain the black grape skin extract;

[0031] (2) Add the black grape skin extract obtained in step (1) into a sodiu...

Abstract

The invention provides a PET compound for a packaging bottle. The PET compound comprises the following components by weight part: 50-60 parts of PET resins, 0.6-1.1 parts of lubricating agents, 5-10 parts of fire retardants, 3-4 parts of flexibilizer, 0.5-1 part of dispersing agent, 1-2 parts of antistatic agents, 5-10 parts of reinforcing agents, 1-2 parts of low temperature-resisting modifying agents, 3-4 parts of compatilizer, 5-6 parts of epoxy resins, 7-8 parts of compound melanin capsules and 2 parts of nylon. The invention also provides a manufacturing method for the PET compound for the packaging bottle. The PET compound has higher radiation resistance.

Description

technical field [0001] The invention relates to a PET composition, in particular to a PET composition used for packaging bottles and a manufacturing method thereof. Background technique [0002] The full name of PET is Polyethylene Terephthalate (polyethylene terephthalate), which is a polymer produced by combining terephthalic acid (Terephthalic acid) and ethylene glycol (Ethylene glycol), referred to as polyester. PET plastic has the characteristics of light weight, high transparency, impact resistance and not easy to break. It can also block carbon dioxide gas and keep soda water steamy. Therefore, PET plastic is suitable for packaging, especially for water and soft drinks. [0003] The general PET bottle production process is to inject the preform after hot-melting the PET polyester chip with color oil, store it in a certain humidity and temperature environment for a period of time, crystallize or not crystallize, and then blow it into a bottle. PET bottles are mainly ...
