Problems solved by technology

[0002] The average wall thickness of the traditional rubber liner is about 1.5mm, and the average thickness of the ultra-thin rubber is 1.25mm. Therefore, during injection production, the rubber material is more likely to vulcanize early in a short period of time, so that the entire mold cavity cannot be filled normally, and the ejection Uneven after molding, or directly useless products

Abstract

The invention relates to an ultrathin water storage device, which belongs to the technical field of water storage devices. The ultrathin water storage device is prepared from the following components by weight percent: 10 to 18 percent of ordinary butyl rubber, 30 to 50 percent of halogenated butyl rubber, 30 to 48 percent of carbon black, 2 to 3 percent of resin, 0.1 to 1 percent of internal releasing agent, and 1.5 to 3.5 percent of flow promoter. The ultrathin water storage device is high in scorching resistance and good in mobility; when in injection production, rubber materials are unlikely to vulcanize early in a short time, a whole mold cavity can be fully filled, and an inferior product is avoided.

Description

technical field [0001] The invention belongs to a water storage treasure, in particular to a household ultra-thin water storage treasure. Background technique [0002] The average wall thickness of the traditional rubber liner is about 1.5mm, and the average thickness of the ultra-thin rubber is 1.25mm. Therefore, during injection production, the rubber material is more likely to vulcanize early in a short period of time, so that the entire mold cavity cannot be filled normally, and the ejection After the mold is uneven, or it is a useless product directly. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the purpose of the present invention is to provide a technical solution for an ultra-thin water storage treasure. [0004] An ultra-thin water storage treasure, which is characterized in that it includes the following components: 10-18% of ordinary butyl rubber, 30-50% of halogenated butyl rubber, 30-48% of carbon black, 2-3% of...
