Abstract

The invention relates to a high barrier anti-aging water cup, and belongs to the technical field of life utilities. The water cup comprises a cup body and a cup lid. The cup lid comprises a small lid and a connection lid. One side of the connection lid is connected with the cup body. The other side is connected with the small lid through thread rotationally. The joint between the cup body and the connection lid is provided with a hanging hook connected by hinges. The cup body and the cup lid are made of the same composite material. The composite material comprises, by weight, 55-70 parts of polypropylene, 7-15 parts of ethylene-vinyl alcohol copolymer, 10-20 parts of poly-meta-xylylene adipamide, 8-15 parts of thermal plastic SEBS, 5-13 parts of modified nano filler, 5-12 parts of compatilizer, 0.02-0.5 part of anti-aging agent and 0.2-0.8 part of lubricant. The cup has the advantages of high barrier, good anti-aging property, excellent mechanical performance, strong impact resistance, less inclination for breaking and long service life.

Description

technical field [0001] The invention relates to a high-barrier and anti-aging water cup, which belongs to the technical field of daily necessities. Background technique [0002] Water cups are generally divided into glass, plastic, ceramics, etc. according to their materials. Glass and ceramic water cups are not resistant to falling, while plastic water cups are more durable, so plastic water cups occupy a relatively large market. Plastic water cups are generally made of materials such as polypropylene (referred to as PP), polycarbonate (referred to as PC) or polyethylene terephthalate (referred to as PET). Among them, PET plastic cups are generally not resistant to high temperatures, and the maximum operating temperature cannot Above 70 ℃, the cup wall is thin, mainly used for packaging carbonated beverages, drinking water, fruit juice, enzymes and tea drinks, etc.; PC is a material that is widely used, especially for making milk cups, space cups, etc., but because Contain...
