Description
Technical field
The present invention relates to polymeric material field, a kind of gas hose is referred specifically to.
Background technology
Flexible pipe is the flexible piece of function admirable in modern industry pipeline, its feature：Corrosion-resistant, high- and low-temperature resistance (- 196 DEG C~
+ 420 DEG C), lightweight, small volume, flexibility is good.Its main application：Conveying has corrosive chemical medium or organic solvent
(such as：Nitrogen water, acetone etc.), the high-temperature medium such as conveying high-temperature gas, deep fat is (such as：Heat steam, conduction oil etc.), transporting low temperature or super
Cryogenic media is (such as：Liquid nitrogen), the medium such as conveying water, gasoline is (such as under hot environment：Water-steam system in steel-making, coking, continuous casting installation for casting
And hydraulic system), it is necessary to which damping or the pipeline that abates the noise are (such as：The import and export of pump).Such as Chinese patent application file (publication number
For the A of CN 102863704) disclose a kind of rubber hose, including raw material and additive, raw material includes haloflex, natural
Rubber and reclaimed rubber；Additive includes filler, reinforcing agent, sun-screening agent, plasticizer and auxiliary agent, and filler is calcium carbonate, increases
Strong agent is carbon black, and sun-screening agent is paraffin, and plasticizer is phosphoric acid aliphatic alcohol ester, adipate ester or epoxidized soybean oil.It is poly- using chlorination
Ethene, natural rubber and reclaimed rubber, with cold resistance and resistance to ag(e)ing, cold resistance is carried with the increase of natural rubber consumption
Height, the rubber hose surface of this invention is without specially treated, not wear-resisting, the lifting using general sun-screening agent to ageing of rubber performance
Effect is not high, and domestic product is using the standby method of general rubber system at present, and the flexible pipe aging prepared is than very fast, toughness
Not strong, mechanical property is bad, is easily damaged during use.
The content of the invention
It is an object of the invention to for defect present in prior art, there is provided a kind of anti-aging, excellent mechanical
Gas hose.
The technical scheme is that：A kind of gas hose, composition is included by mass parts：100~120 parts of nitrile rubbers, 1
~2 parts of vulcanizing agents, 50~60 portions of reinforcing agents, 3~6 parts of age resistor, 12~20 parts of plasticizer, 4~5 parts of zinc oxide, 1~2 part it is hard
Resin acid, wherein after the coarse processing of the surface chemistry of the gas hose, surface sand-blasting.
Gas hose is after chemical coarse processing, and surface can form the particle of projection, when being contacted with other objects,
The tip of particle can wear and tear first, protect the surface of gas hose, chemistry is coarse to make the particle that surface is formed than more uniform, no
Can occur the serious phenomenon of concentrated wear.After sandblasting, surface can form multipoint raised grain structure, in use usually
Cheng Zhong, what is worn and torn first is these surfaces protrusion, so that indirect protection underlying surfaces, are unlikely to whole surface overall wear.
Further, 5~8 mass parts PbWO are also included in the composition of the gas hose4Powder, the PbWO4Powder
Particle mean size is 200~250 mesh.By PbWO4Powder is added in gas hose, PbWO4Powder, can be with as inorganic scintillator
The radiation in environment is absorbed, radiation-resistant ability of gas hose is improved, and radiation is an important original of gas hose aging
Cause.PbWO4The undersized of powder can cause to reunite during raw material is dispersed in, and be unfavorable for disperseing, and play PbWO4's
Effect, and if granularity is excessive, because the hardness between inorganic particle and rubber differs larger, inorganic particle can influence rubber
Mechanical property, can reduce the last plasticity of gas hose if granularity is excessive, the mechanical property such as tensile strength.
Further, above-mentioned PbWO4The preparation technology of powder is：
1) by the Na of equivalent2WO4With Pb (CH3COO)2It is dissolved separately in PEG200 solution, Na is made2WO4Solution and Pb
(CH3COO)2Solution；
2) in Na2WO4Solution sequentially adds methacrylic acid (MAA) and citric acid, is uniformly mixing to obtain precursor solution；
3) Pb (CH are added in the precursor solution3COO)2Solution, stirring reaction is precipitated, by the mud chamber
Temperature obtains PbWO after drying4Powder.
Make the PbWO prepared in this way4Powder granularity is uniform, and purity is higher, is easily divided in rubber raw materials
Dissipate uniform, the plasticity of gas hose is not influenceed while gas hose mechanical property is improved.
Further, the fine mass percent of propylene is 31~34%, the door of the nitrile rubber in the nitrile rubber
Buddhist nun's viscosity is 60~80.The Mooney viscosity of nitrile rubber can cause large effect to the plasticity after rubber-moulding, and viscosity is excessive
Processing characteristics is influenceed, the too small gas hose mechanical property ultimately produced of viscosity is inadequate.Due to PbWO can be added in the present invention4Powder
Body, the addition of powder can reduce the plasticity of gas hose, control the Mooney viscosity of nitrile rubber in raw material and can make the finished product being made
Gas hose keeps preferable plasticity.
Further, the vulcanizing agent is the Sulfur of 1.2~1.4 mass parts and the N- cyclohexyls -2- of 1.5~2 mass parts
The mixture of benzothiazole sulfenamide.
Further, the chemical coarse handling process is：Gas hose is impregnated into 10-15min, surface in concentrated sulfuric acid
First cleaned after hardening with 5-10% ammoniacal liquor dipping 5min, again with distilled water, then two chloroethenes of the 5-10% metatitanic acid tert-butyl ester
Alkane solution brushing, then cleaned with clear water.
Further, the surface sand-blasting technique is：Using ceramic sand grains, under 3~4kg of pressure, sandblasting distance 50~
60cm, 1~2min of sandblasting.
Using the coarse processing of chemistry relative to mechanical treatment is used, it can not change not right while the mechanical property of rubber
Rubber surface causes damage, and causes surface thinning, or is a stepping next because mechanical force is destroyed the tissue of rubber
Row sandblasting can reserve larger leeway.After sandblasting, surface can form multipoint raised grain structure, in use usually
Cheng Zhong, what is worn and torn first is these surfaces protrusion, so that indirect protection underlying surfaces, are unlikely to whole surface overall wear.
Further, the reinforcing agent is one or both of carbon black, tripoli.
Further, the age resistor is the one or more in 4010NA, RD, paraffin.
Further, the plasticiser be Phthalates, aliphatic dicarboxylic esters of gallic acid, fatty acid ester, phosphoric acid ester,
One or more in polyesters, epoxies.
The present invention is relative to the advantage of prior art：
(1) surface carries out chemical coarse and blasting treatment, in use can the raised particle of wear surface, and then improve first
Anti-wear performance during gas hose use.
(2)PbWO4The addition of powder, environmental radiation is can absorb as inorganic scintillator, reduces the aging speed of gas hose
Degree, improves the service life of gas hose.
