Description
Technical field
The present invention relates to the rubber product industry in chemical industry field, also is glue tube industrial, specifically, relates to a kind of can be used in and carries the rubber hose that contains the aromatic hydrocarbon solvent material.
Background technique
At printing ink, make lacquer, coating, chemical industries such as plastics are extensive use of with toluene, dimethylbenzene is the aromatic hydrocarbon solvent of representative, and for fear of environment is polluted, how to carry this kind solvent and the material that contains this kind solvent with closed pipeline, therefore, in some occasion, unavoidably to use rubber hose (hereinafter to be referred as sebific duct) and so on flexible pipe to connect and carry, problem is the rubber material of using always, comprise not anti-this class aromatic hydrocarbon solvent of nitrile butadiene rubber that is celebrated with oil resistance, the rubber hose of making is after using through the short time, will soon damage and scrap, have to be changed.
For this reason, some producer's employing is made the MULTILAYER COMPOSITE sebific duct with PVC as inner glue layer and is applied to this class purposes, but subduing property of PVC is poor, bond properties is also undesirable, so that in the sebific duct operations for forming, to use the bigger solvent of toxicity, the sebific duct of making is not flexible, brings inconvenience to the user.
Through looking into, fluorine rubber has preferable anti-aromatic hydrocarbon solvent performance in many rubber, but costing an arm and a leg of fluorine rubber, the viscosity height, technology capability is poor, makes sebific duct with it and have certain difficulty on technology, in recent years, along with the appearance of low mooney viscosity fluorine rubber, the process industrial art performance of fluorine rubber has obtained improvement to a certain degree, but the price of this type of fluorine rubber is more expensive.For this reason, industrial much more general the employing made liner with the thin layer fluorine rubber, covers other rubber layer outward and reduces cost as the method for transition layer and make full use of the medium-resistance of fluorine rubber excellence and be difficult for permeability.Yet, fluorine rubber is because its main chain is subjected to the shielding action of fluorine atom, cause it and other rubber to be difficult for bonding, the curing system and other rubber that add it are inconsistent, it and other rubber combined difficulty have more been increased, U.S. Pat P4806351 has disclosed a kind of fluorine rubber and nitrile butadiene rubber composite methods, it is said the manufacturing that can be used for sebific duct, but in the manufacturing of the fabric hose of proof pressure, general factory uses usually and embrocates the fabric of natural rubber rubber cement or latex as canvas filler layer, bond properties based on the transition layer of nitrile butadiene rubber and natural rubber is not good, embrocate canvas filler layer if use nitrile butadiene rubber instead and be the rubber cement of main body, then complex process and be difficult to take into account simultaneously the superior neoprene of ageing-resistant ozone resistance that adopts usually with outer glue-line and realize bonding not only.
Summary of the invention
For overcoming above-mentioned shortcoming, the present invention aims to provide and a kind ofly is suitable for carrying the material rubber hose that contains aromatic hydrocarbon solvent by what multiple tube wall was composited, it both can use the canvas filler layer of embrocating natural rubber, used transition layer can be taken into account bonding with fluorine rubber again, does not also hinder and adopts the superior neoprene of ageing-resistant ozone resistance as outer glue-line.
The present invention is achieved in that the formation of described multiple tube wall compounded rubber flexible pipe comprises: based on the inside liner of fluorine rubber; The transition layer made from the neoprene of special cooperation; The enhancing made from rubberized fabrics is with canvas filler layer with based on the outer glue-line of the neoprene of ageing-resistant cooperation.
Wherein, be used for directly contacting based on the inside liner of fluorine rubber with material of being carried that contains aromatic hydrocarbon solvent or simple aromatic hydrocarbon solvent, so require to have remarkable anti-aromatic hydrocarbon solvent performance, promptly this layer rubber material can not also be difficult for being permeated by aromatic hydrocarbon solvent by aromatic hydrocarbon solvent institute swelling.For this reason, adopt the fluorine rubber of anti-aromatic hydrocarbon solvent performance the best to make as material of main part.The fluorine rubber that is suitable for can be the ternary system fluorine rubber of forming with the binary system of biasfluoroethylene-hexafluoropropylene composition or biasfluoroethylene-hexafluoropropylene-tetrafluoroethylene, as the domestic three Ai Fu company trades mark is the fluorine rubber of F2601, F2602, F2604, F2605 and F2462, F2463 etc., as long as can make the sizing material that obtains to adapt to the fabric hose shaping operation and just can by suitable cooperation.
The curing system of fluorine rubber has many kinds, comprise amine, polyatomic phenol, peroxide etc., for the present invention, curing system should adopt with the many alcohol of fragrance as vulcanzing agent, organic quaternary amine or season phosphonium salt as promoter, because this type of curing system technology capability is good, compression set is little, and helps bonding.The amount of vulcanzing agent is 100 weight portions in rubber, is preferably 1.5～2.0 weight portions, and the amount of promoter is 0.5～1.5 weight portion.Vulcanzing agent such as bisphenol-A and the bisphenol A used, promoter such as tetraphenylphosphonium chloride, benzyl triphenyl phosphonium chloride phosphine, tetraphenylphosphonichloride chloride ammonium etc.
The auxiliary agent of other uses comprises: reinforcing agent carbon black, acid-acceptor MgO and Ca (OH)
2And according to other selected auxiliary agent of service condition.Emphasize to be pointed out that the fluorine rubber material of setting by above prescription has good anti-aromatic hydrocarbon solvent performance.
This layer is preferably 0.3～1.5mm based on the thickness of the inside liner of fluorine rubber, and thickness is thin excessively, and promptly less than 0.3mm, second the shaping operation difficulty is easily seen through by solvent first, can not reach the present invention's purpose.Otherwise thickness is excessive, can cause the waste of expensive fluorine rubber, and is unfavorable in the cost of product.
The described transition layer made from the neoprene of special cooperation is used to be coated on the outside of fluorine rubber inside liner, form the inner glue layer of sebific duct of the present invention with very thin fluorine rubber inside liner, so require it to form excellent bonds, also will have excellent adhesion performance with canvas filler layer to the enhancing of embrocating natural rubber with the fluorine rubber inside liner.For this reason, the present invention selects for use bond properties outstanding, has the material of main part of the neoprene of suitable oil resistant solvent resistance as this transition layer again, and special in addition cooperation means make it that fluorine rubber is also had good Adhesion force.Described special cooperation means be meant except that adopt general neoprene cooperate general zine oxide, the magnesium oxide curing system, added specially and an amount of fluorine rubber has been had Active agent and acid-acceptor effect, can participate in the calcium hydroxide that the crosslinked fluororubber network forms, to help bonding to fluorine rubber.Its consumption is 100 weight portions in neoprene, is preferably 10～30 weight portions.Consumption is less than 10 weight portions, can cause the bond properties deficiency with fluorine rubber, and consumption then influences the traditional performance of neoprene more than 30 weight portions, as intensity, compression set etc.The thickness of this transition layer is advisable with 1～2mm.
