Abstract

The invention relates to a water cup with scratch resistance and high barrier property and belongs to the technical field of articles for daily use. The water cup comprises a cup body and a cup cover, wherein a plurality of concave points with equal intervals are distributed in the peripheral surface of the cup body; the cup body is connected with the cup cover in a manner of thread rotation; a rope penetrating port is arranged at the upper end of the cup cover; and the cup body and the cup cover are made of a same composite material. The composite material comprises the following components in parts by weight: 50-70 parts of polypropylene, 5-12 parts of ethylene-vinyl alcohol copolymer, 8-18 parts of poly-meta-xylylene adipamide, 5-12 parts of polymethyl methacrylate, 3-10 parts of nylon, 5-10 parts of modified nanofiller, 5-12 parts of compatilizer, 0.5-2 parts of silicone master batch and 0.1-1 part of lubricant. The water cup has the advantages of good scratch resistance, high barrier property, excellent mechanical property, large impact strength, difficult breaking and long service life.

Description

technical field [0001] The invention relates to a scratch-resistant and high-barrier 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 polypropylene (PP), polycarbonate (PC) or polyethylene terephthalate (PET), among which PET plastic cups are generally not resistant to high temperatures, and the maximum operating temperature cannot exceed 70°C , 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 the manufacture of baby bottles, space cups, etc. (BPA) has been controversial. The European Union believes ...
