Example Embodiment

[0023] Example one:

[0024] Adopting acrylic butyl polymer and high-pressure polyethylene in a ratio of 1:9, through mixing and granulating process to make granular products, and then extruding the pipe through a single-screw extruder to obtain an inner diameter of 12MM, wall A rubber tube with a thickness of 1.5MM. The rubber tube undergoes the above-mentioned electronic irradiation process and uses a dose of 8 megaelectron volts for irradiation cross-linking reaction. The rubber tube passes through the irradiation device at a constant speed at a rate of 8 m / s, and the irradiated product passes through After the tube is expanded and formed, a rubber tube with a tube expansion rate of 10% is finally obtained.

Example Embodiment

[0025] Embodiment two:

[0026] Adopting acid anhydride grafted polyethylene and ethylene-vinyl acetate copolymer, after the above-mentioned mixing granulation process, the pellet product exceeds the single-screw extruder for extrusion pipe production, and a rubber pipe with an inner diameter of 12MM and a wall thickness of 1.5MM is obtained. The rubber tube undergoes the above-mentioned electronic irradiation process with a dose of 4 megaelectron volts, and the cross-linking reaction is irradiated. The rubber tube passes through the irradiation device at a constant speed of 8 m / s. The irradiated product is finally made by expanding the tube. A hose with an expansion rate of 10%.

Example

[0028] Specific application embodiment 1:

[0029] In the water dispenser, an expanded diameter radiation cross-linked heat shrinkable hose is used. The hose is inserted into the two connecting ends of the hose in the water dispenser, and then the connection is heated by an electric heating air gun at the interface, so that the hose at the connection is contracted, and tightly clamped on the hose connection port of the water dispenser, even if it is subjected to Hot water at 100°C still maintains a firm connection, will not fall off, and is non-toxic and odorless.

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. ...
