2, innermost layer is an elastomer layer, because nylon alloy is made the elasticity that inside liner can reduce the body that contacts with the cast link (generally being made of metal) of rigidity, be difficult to keep satisfactory sealing, therefore adding an elastomer layer makes innermost layer, can improve the airtight quality and the endurance of flexible pipe at the rigid connector place.
Embodiment
Advanced composite material (ACM) automotive air conditioning hose structure is followed successively by outer glue-line, framework layer, inner glue layer, nylon alloy inside liner from outside to inside, can strengthen adhesive effect by adhesive between inside liner and the inner glue layer, nylon alloy is the mixture of polyamide resin, have excellent anti-F134a permeability and the mixed solution of anti-F134a/PAG, its composition and performance are as shown in the table:
Because nylon alloy is made the elasticity that inside liner can reduce the body that contacts with the cast link (generally being made of metal) of rigidity, is difficult to keep satisfactory sealing.Therefore adding an elastomer layer makes innermost layer, can improve airtight quality and the endurance of flexible pipe at the rigid connector place, the elastomer internal layer had both required that F134a was had hypotonicity, also require to have better elastic and little compression set, thisly be used to improve the infiltrative automotive air conditioning hose of heat-resisting refrigeration agent, constitute by outer glue-line, framework layer, inner glue layer, polyamide nylon alloy lining layer, thermoplastic sulfurized rubber elastomer layer from outside to inside.Thermoplastic sulfurized rubber is made up of polypropylene and EPDM mixing IIR or CI-IIR or CSM; The component of polyamide nylon alloy lining layer is nylon-6, PA-12 and improved polyalkene; What shoe covered polyamide nylon alloy lining layer is EPDM or brombutyl inner glue layer; Framework layer is formed by the polyester fibre braiding; Outer glue-line is EPDM or halogenated butyl rubber.
Elastomer layer, the nylon alloy inside liner has good gasproof body breathability and refrigeration agent permeability, but because the rigidity of nylon alloy makes that inside liner elasticity is relatively poor, so difficulty that has caused pipe fitting to install, and because nylon alloy directly contacts with metal parts, easily mis-behave be damaged.Be that innermost layer then can improve elasticity and avoid the problem of intermediate peeling with the rubber material, but gasproof body permeability and anti-refrigeration agent breathability aspect can descend again to some extent, the way of its solution is to do innermost layer with elastomer layer, polyamide resin or resin and rubber composition are done inside liner, thereby are keeping elasticity to play the iris action good to refrigeration agent simultaneously.The rubber material that the elastomer internal layer adopts is as follows: NBR, CSM, CPE(haloflex), the CHC/CHR(epichlorohydrin rubber), the CR(chloroprene rubber), the C1-IIR(chlorinated scoline).
Inside liner mainly plays the iris action to F134a, requires to have the low breathability to F134a, to the anti-patience of oiling agent PAG, and the anti-patience under 30-150 ℃ of operating temperature etc.Polyamide resin has excellent R12 of anti-refrigeration agent the and F134a penetrability.But use one pack system polyamide resin such as nylon-6, nylon-66, nylon-11 and PA-12 etc. are done the sebific duct inside liner, are difficult to satisfy many performance requirements of air conditioning hose, develop nylon alloy for this reason.Nylon alloy is to disperse PA-12 island phase in the marine facies of nylon-6, again the 3rd component modification polyolefin is sneaked into the island phase, constitute complicated dispersion, the excellent compatibility of PA-12 and nylon-6, make its interface compatible closing fully, thereby make mixture have 3 kinds of polymer property concurrently.Particularly importantly big or small mutually the wanting in island suitably just can reach each component characteristic balance when constituting hybrid structure, satisfies the requirement of flexible pipe heat resistance, anti-PAG and resistance to persistence.The characteristics of nylon alloy are as follows: 1, gasproof body good penetrability; 2, good heat resistance; 3, anti-mixing fluidity is good.
Inner glue layer is same, and to require to have lower anti-F134a breathability, IIR to have lower to the F134a transmittance, is desirable inner glue layer material, secondly is the NBR of HNBR and high acrylonitrile mass fraction.Inner glue layer also requires to have and inside liner, adhesive effect that framework layer is good.Because the fusing point of nylon alloy is more than 160 ℃, processing difficulties, with inside and outside two glue-line poor adhesion, vibration easily comes off down, therefore adopts the low rubber material of F134a permeability such as butyl rubber and halogenated butyl rubber are made inner glue layer.
Framework layer can be used cellulose ester, polyamide fiber and polyester fibre etc.Cellulose ester is better than cotton fiber on heat resistance, but it is poor than cotton fiber with the bond properties of rubber, easily moisture absorption causes reduction in strength, chemical-resistance is relatively poor, and the rubber product framework material has two kinds of nylon-6 and nylon-66s with polyamide fiber, and the former chemical name is a capron(e), latter's chemical name is for gathering oneself two phthalein hexamethylene diamine fibers, the rupture strength height of nylon fiber, hydroscopicity is lower, and wet dry strength ratio can reach 90% one 95%.Be out of shape greatly under the tensile force effect, the elasticity resistance to heat is relatively poor, shows as with the temperature rising and produces thermal shrinkage and reduction in strength, and Young's modulus is low, poor dimensional stability, but fatigue resistance is rather good; Wear-resisting property is splendid, than the excellent in abrasion resistance of cellulose ester; Not good with the rubber adhesion performance, need immersion treatment: alkaline-resisting not acidproof, dissolve in dense inorganic acid, dense formic acid, the halogenated acetic acids: light fastness is bad, be subjected to for a long time behind the solar radiation because of the high polymer degree of polymerization reduction in strength that descends, polyester fibre is not only modulus raising after heat setting, and percent thermal shrinkage reduces, and is desirable framework layer material.Compare with nylon fiber, rupture strength and elongation at break are low slightly; Fatigue resistance is not as good as nylon; Impact strength is higher 4 times than nylon; Initial modulus is higher than nylon, and dimensional stability is better than nylon fiber.Heat resistance is better than other fiber; High abrasion resistance.Be only second to nylon fiber; Acidproof, not alkaline-resisting, in denseer or alkali lye that temperature is higher, can destroy; Sunlight resistance and weatherability are only second to polyacrylonitril fiber, are better than other synthetic fiber, also are better than cotton fiber and cellulose ester.
It is EPDM or halogenated butyl rubber that outer glue-line adopts, and excellent oil resistance, ageing-resistant, abrasion performance, low characteristics such as ventilative are arranged
For improving the adhesive effect between inside liner and inner glue layer, framework layer and inner glue layer and the outer glue-line, in general, by in elastomeric compound, adding the key tackiness agent or by fabric face is carried out adhesive treated, perhaps two kinds of methods and be used for improving the bonding strength of rubber and fiber.No matter what advanced composite material (ACM) automotive air conditioning hose structure adopted is that innermost layer is the four-layer structure of nylon alloy inside liner; still innermost layer is the five-layer structure of elastomer layer; its innermost layer all must satisfy the obstruct requirement to F134a/PAG oil; inner glue layer will have good anti-patience and osmotic-pressure-tolerant to F134a/PAG, outer glue-line to framework layer play a protective role and to external world environment tolerance is arranged.
It below only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
