Description
Technical field
The utility model relates to air-conditioning technical field, particularly relates to a kind of idle call flexible pipe.
Background technique
Current automotive air conditioning hose main material is inner rubber layer, nylon layer, mesoglea, fiber yarn enhancement layer, outer glue-line.Be mainly used to intercept R134a refrigeration agent, but rubber process is complicated, power consumption and investment are comparatively large, and easily cause environmental pollution.Its barrier does not reach the requirement of domestic air conditioner, cannot promote in domestic air conditioning.
Present domestic air conditioning indoor and outdoor machine connecting tube is mainly the metal pipe such as copper pipe or aluminum pipe, though this type of metal pipe has excellent barrier, metal mine is non-renewable resources, and it is huge, seriously polluted that metal itself manufactures energy consumption, and cost of production is higher.
Existing air conditioning hose production technology and existing air conditioning hose model utility all use nylon (PA, i.e. polyamide) as barrier layer substantially.Have very not many compared with high barrier, low, that there is the again workability model of cost of production at PA6 (nylon 6) and the large class material of PA66 (nylon66 fiber) two.
Model utility content
The purpose of this utility model is, for above-mentioned defect, to provide a kind of air conditioning hose, to reach better barrier property, reduces cost of production, improves the practicability of product, avoid the waste to metals resources.
The technological scheme that the invention for solving the technical problem adopts is:
A kind of idle call flexible pipe, this air conditioning hose wall comprises internal layer TPV, compound barrier layer, layer of compensation TPV, enhancement layer and outer TPV from inside to outside successively, described compound barrier layer is bonded by PA/EVOH/PA/EVOH/PA interval layering co-extrusion, and described internal layer TPV and compound barrier layer and described layer of compensation TPV are bonded semifinished tube by co-extrusion.
Described enhancement layer to be wound around by the chemical fiber yarn of chemical fiber yarn or coated (dipping) tackiness agent or resistant to rust wire or braiding is coated on semifinished tube.Described outer TPV is by extruding coating and bonding on the enhancement layer of semifinished tube.
Described internal layer TPV, layer of compensation TPV and outer TPV are Ethylene Propylene Terpolymer and polyacrylic thermoplastic elastomer (TPE).
Described compound barrier layer adopts the bonding of PA/EVOH/PA/EVOH/PA interval layering co-extrusion, and each layer thickness is 0.01mm-1mm, and for guaranteeing barrier property and the ductility of air conditioning hose, the utility model preferably adopts 3-9 interlayer every the compound barrier layer of layering.
Described barrier layer also can with half compound barrier layer, as half compound barrier layer of the 3-9 layer that layering co-extrusion in TPV/EVOH/PA/EVOH/TPV interval is bonded.
The barrier layer that described barrier layer also can be made up of multilayer EVOH, as the barrier layer of the 3-9 layer that layering co-extrusion in TPV/EVOH/TPV/EVOH/TPV interval is bonded.
This flexible pipe preferentially adopts compound barrier layer.
Described EVOH (ethylene/vinyl alcohol copolymer) is high barrier material, is main barrier layer, and it can reach the 50-100 of nylon doubly to the barrier of refrigerant gas, and EVOH also exists serious defect, i.e. hydrophily.Even if malaria also can make its barrier greatly decline, so it can not be used alone as efficient barrier material, corresponding protective layer must be had to use.Although PA also has barrier, its major function is protection EVOH, and at a suitable temperature, EVOH and PA can be sticked together by co-extrusion.Compound barrier layer containing EVOH can reuse completely, effectively can avoid the pollution of the wasting of resources and environment, reduce costs.
A production method for idle call flexible pipe, comprises the following steps:
(1) semifinished tube of co-extrusion internal layer TPV/ compound barrier layer/layer of compensation TPV, co-extrusion semifinished tube at the temperature that layers of material controls separately in each section on respective extruder, its control temperature is respectively: TPV layer temperature is 170-230 DEG C, PA layer temperature is 200-280 DEG C, and evoh layer temperature is 155-240 DEG C;
(2) enhancement layer yarn is coated on semifinished tube by being wound around or weaving by the semifinished tube that step (1) obtains.Be woven on semifinished tube according to wire-reinforced layer and then directly obtain production tube;
(3) semifinished tube of the enhancement layer of coating cotton thread step (2) obtained is coated on yarn enhancement layer by extruding outer TPV, namely becomes production tube.
Domestic air-conditioner soft pipe barriering effect of the present utility model is very good, and low production cost cost only has 1/3rd of copper pipe.The copper pipe that domestic air conditioner indoor and outdoor machine can be replaced to connect or aluminum pipe.Thus save strategy metal copper, it also avoid the defect using aluminum pipe.This product safety is nontoxic has fabulous flame-proof anti-aging, and practicability is extremely strong.Simultaneously this flexible pipe also can be used as automotive air conditioning hose and uses on car air conditioner.
