Abstract

The invention discloses a plastic material for a beverage bottle. The plastic material is prepared from the following raw materials in parts by weight: 80 to 120 parts of polyethylene glycol terephthalate, 25 to 35 parts of fillers, 0.1 to 0.3 part of antioxidants, 1 to 3 parts of compatilizers, 2 to 4 parts of nucleating agents, 1 to 3 parts of plasticizers and 2 to 4 parts of lubricating agents,wherein the nucleating agents are Na-based montmorillonite, nanometer magnesia, sodium chloride and polyoxyethylene. The plastic material has the advantages that the crystallization speed is high; the crystallization time consumption is short; the anti-impact performance is good.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a plastic material for beverage bottles. Background technique [0002] Polyethylene terephthalate is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It has excellent physical and mechanical properties in a wide temperature range, and the long-term use temperature can reach 120 ° C. It has excellent electrical insulation and is often used as a beverage bottle material. [0003] However, the crystallization rate of polyethylene terephthalate is slow, the molding process is difficult, the molding temperature is high, the production cycle is long, and the impact performance is poor. The use of polyethylene terephthalate is restricted. Contents of the invention [0004] Based on the technical problems in the background technology, the present invention proposes a plastic material for beverage bottles. The present invention has fast cryst...
