Embodiment 1

[0024] Using acrylic acid butyl polymer and high-pressure polyethylene in a ratio of 1:9, through a mixing and granulation process, a granular product is made, and then extruded through a single-screw extruder to obtain a tube with an inner diameter of 12MM and a wall. A rubber hose with a thickness of 1.5MM, the rubber hose undergoes the above-mentioned electron irradiation process, and the radiation cross-linking reaction is carried out with a dose of 8 MeV. The rubber hose passes through the irradiation device at a constant speed of 8 m / s, and the irradiated product passes through After the tube is expanded and formed, a rubber tube with a tube expansion ratio of 10% is finally produced.

Embodiment 2

[0026] Using anhydride-grafted polyethylene and ethylene-vinyl acetate copolymer, after the above mixing and granulation process, the granule product is then extruded by a single-screw extruder to produce a rubber hose with an inner diameter of 12MM and a wall thickness of 1.5MM. After the above-mentioned electron irradiation process, the rubber hose is carried out with a dose of 4 MeV, and the irradiation cross-linking reaction is carried out. The rubber hose passes through the irradiation device at a constant speed of 8 m / s, and the irradiated product is finally obtained by expanding the tube. Rubber hose with 10% expansion ratio.

Abstract

The present invention belongs to the field of drinking water tube, in particular, it relates to a connecting tube for water-driving machine. It is characterized by that said connecting tube is a hose made up by using thermoplastic elastomer high-molecular material through radiation crosslinking process.

Description

Technical field: [0001] The invention relates to the technical field of drinking water pipes, in particular to a connecting pipe for drinking water machines. Background technique: [0002] Due to assembly reasons, the water dispenser needs to use some soft connecting water pipes. These water pipes are required to be non-toxic, tasteless, and resistant to low and high temperatures (long-term use needs to withstand temperatures around 100-120°C). At present, water dispenser manufacturers generally use silicone tubes, because during the production of silicone tubes, it is necessary to add vulcanizing agents, vulcanization accelerators and other additives to the silicone rubber, and then mold and vulcanize. The addition of these additives will cause the silicone tube to be toxic, odorous, and easy to age. In addition, the main raw material silica gel used needs to be prepared by a special process, and its price is expensive, which also results in an increase in product cost. ...
