Abstract

The invention discloses a permeability-resistant air conditioner hose. The permeability-resistant air conditioner hose comprises a lining layer, a rubber impermeable layer, a barrier layer, a first buffering layer, a rubber layer, a second buffering layer and a rubber protective layer in sequence from inside to outside; the lining layer is made of a modified polyamide nylon alloy which is preparedby blending polyamide and carboxyl-containing modified polyolefin; the rubber impermeable layer is ethylene propylene diene monomer rubber, butyl rubber, brominated butyl rubber or chlorinated butylrubber; the barrier layer is a multi-layer composite barrier layer; the multi-layer composite barrier layer is formed by compounding PA (Polyamide) plastics + PA plastics + PA plastics + PA plastics;the rubber layer is porous butyl rubber, porous ethylene propylene diene monomer rubber or porous chlorinated butyl rubber, wherein the porosity of the rubber layer is 35 to 45 percent, the aperture of the rubber layer is 0.2 to 0.3 mu m, and the thickness of the rubber layer is 0.6 to 0.8 mm; the first buffering layer is formed by weaving chemical fibre yarns, metal wires or glass fibre yarns; the second buffering layer is formed by weaving organic fibres,; the organic fibres are obtained by carbonization treatment and graphitization treatment; and the carbon content of the organic fibres is95 to 99 percent. The air conditioner hose disclosed by the invention has high permeability.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a permeation-resistant air-conditioning hose. Background technique [0002] With the increasing trend of global warming, more and more attention has been paid to limiting the emission of greenhouse gases. The traditional R134a refrigerant has a high greenhouse effect index and is corrosive to copper pipes. It has been gradually replaced by new refrigerants such as Replacement of carbon dioxide, etc., puts forward higher requirements on the impermeability of the pipeline. Most of the existing air-conditioning hose structures are composed of nylon shielding layer, inner rubber layer, braided layer, and outer rubber layer. The air-conditioning hoses of these structures have the problem of low permeability resistance and cannot meet actual needs. Contents of the invention [0003] The object of the present invention is to provide a permeation-resistant air-condi...
