Modified composite plastic for production of plastic casing of thermos flask

Abstract

The invention provides modified composite plastic for production of a plastic casing of a thermos flask. The modified composite plastic is prepared from raw materials in parts by weight as follows: 45 parts of PVC (polyvinyl chloride), 12 parts of polyester resin, 3.5 parts of epoxy resin, 2.5 parts of carbon black, 1.5 parts of pigment, 2.5 parts of titanium dioxide, 2.5 parts of superfine barium, 1.2 parts of a leveling agent, 0.8 parts of a brightening agent, 0.1 pats of graphene, 1.2 parts of nano titanium nitride, 0.8 parts of a rare earth mixture, 0.5 parts of phosphotungstic acid, 0.5 parts of quartz and 2.5 parts of modified zeolite powder. The modified composite plastic is reasonably proportioned, graphene nanoplatelets are added, the coloring performance of the material is improved, and the material has excellent chemical resistance and weather resistance; with the addition of the modified zeolite powder, the material is easier to disperse during compounding, and the temperature of an extrusion composite process is reduced; the material is used for one-time forming of the casing of the thermos flask and has natural colors, high strength and good impact resistance.

Description

technical field [0001] The invention relates to the technical field of plastic product production, in particular to a modified composite plastic used for producing the plastic shell of a thermos bottle. Background technique [0002] The thermos bottle is a vacuumized double-walled bottle as a liner and a heat preservation container formed by a cover shell. In modern society, a thermos bottle is one of the indispensable items in people's daily life. Vacuum bottles can be divided into three categories: (1) Thin mouth type: small mouth diameter, good heat preservation performance, mainly used for holding boiling hot water, decocting hot Chinese medicine juice, hot drinks and cold drinks, etc.; (2) Large mouth type: The diameter of the mouth is large, and the items are easy to pick and place. It mainly holds ice cubes, ice cream, cold drinks with containers, iced medicine, liquid gas, anti-fermentation substances, etc., and can also hold hot food, hot drinks with containers, etc...

AI Technical Summary

Problems solved by technology

At present, the shells of thermos bottles used in daily life are mostly made of plastic materials, but the existing materials used for the shells of thermos bottles have poor anti-aging ability. Has a larger wall thickness and a larger overall weight
