Abstract

The invention relates to a PET composite material for beer packaging and its preparation technology. The composite material is composed of the following components by weight: 62-73 parts of polyethylene terephthalate, 25-35 parts of glass fiber, 5-15 parts of an interfacial compatibilizer, 0.05-0.2 part of an anti-oxidant, 0.05-0.15 part of a cross-linking agent, and 1-3 parts of a lubricant. Theinvention also includes a preparation technology of the PET composite material for beer packaging. The PET composite material for beer packaging of the invention has the advantages of good impact resistance, tensile strength and bending resistance, easy processing and moulding, and low manufacturing cost, thus being especially suitable for the packaging of beer bottles, etc. Characterized by simple preparation technology, the composite material provided in the invention is suitable for industrial production.

Description

technical field [0001] The invention relates to a polyester composite material and a preparation process thereof, in particular to a PET composite material for beer packaging and a preparation process thereof. Background technique [0002] PET, also known as polyethylene terephthalate, not only has excellent wear resistance, heat resistance and chemical resistance, but also has good transparency, gloss and good appearance. Because PET has the above-mentioned advantages, it can be widely used for packaging various beverages. However, when packaging mineral water, beer, and fruit juice drinks, it often affects the application in the field of beer packaging due to its insufficient strength, thus limiting the application of PET as an engineering plastic. application range. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a PET composite material for beer packaging with good impact resistance, bending resistance and t...
