Abstract

The invention provides a top sealing ring of a plastic thermos bottle stopper. A material for making the top sealing ring is formed by compositing raw materials in parts by weight as follows: 30 parts of polyethylene, 1.5 parts of glass fibers, 0.08 parts of phenyl-alpha-naphthylamine, 0.1 parts of triphenyl phosphate, 21.8 parts of polyester, 19.9 parts of epoxy resin, 1.9 parts of a rubber accelerator, 23.5 parts of barium carbonate, 2.5 parts of 6,000-mesh superfine barium, 1.5 parts of titanium dioxide, 0.65 parts of a leveling agent, 0.2 parts of copper gold powder, 0.01 parts of graphene, 0.3 parts of talc and 0.5 parts of modified zeolite powder. The top sealing ring has better ageing resistance in the high-temperature environment, has better flexibility at the temperature of subzero 35-150 DEG C, is high in elasticity and good in shape restoration performance and cannot stick to other objects after long-term sealing.

Description

technical field [0001] The invention relates to the technical field of plastic product production, in particular to a plastic thermos bottle stopper and its top sealing ring. 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.; (3) cups Type: Large mou...
