Abstract

The invention discloses an anti-aging air conditioning hose. The anti-aging air conditioning hose sequentially comprises a rubber anti-permeation layer, a blocking layer, a first buffer layer, a rubber layer, a second buffer layer and a rubber protection layer from inside to outside, wherein the rubber anti-permeation layer is made of ethylene propylene diene monomer rubber, butyl rubber, brominated butyl rubber or chlorinated butyl rubber, the blocking layer is a multi-layer composite blocking layer, the rubber layer is made of one kind of porous butyl rubber, porous ethylene propylene dienemonomer rubber or porous chlorinated butyl rubber, the porosity of the rubber layer is 35-45%, the hole diameter is 0.2-0.4 microns, the thickness is 0.6-0.9 mm, the first buffer layer is formed by weaving chemical fiber yarns, metal wires or glass fiber yarns, the second buffer layer is of a one-layer or multi-layer structure formed by weaving organic fibers, the organic fibers are obtained through carbonization treatment and graphitization treatment, and the carbon content of the organic fibers is 90-99%. The anti-aging air conditioning hose has relatively high rigidity and bearing capacity,and has relatively good anti-aging performance, and the service life of the air conditioning hose can be prolonged.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to an aging-resistant air-conditioning hose. Background technique [0002] The air-conditioning hose is a connecting hose used in the air-conditioning and refrigeration system. The compressor, the condenser and the evaporator, and the condenser and the evaporator need to be connected with a rubber hose. Most of the existing air-conditioning hose structures are composed of nylon shielding layer, inner rubber layer, braided layer, and outer rubber layer. The outer rubber layer protective layer of the air-conditioning hose is directly in contact with the atmospheric environment, and it needs to have excellent weathering resistance. And ozone aging and other characteristics to prevent the aging of air-conditioning hoses and reduce the service life. Contents of the invention [0003] The object of the present invention is to provide an aging-resistant air-conditioni...
