Description
Technical field
The invention belongs to technical field of rubber material, in particular relate to a kind of high-elastic anticorrosive wear-resistant oil resistant rubber material
Material.
Background technique
Rubber material refers to the connection sealing joints being used in underground engineering pipeline, when the concrete cast-in-situ of infrastructure project
The permanent deformation being equipped with stitches and has elastomeric seal rubber suitable for the engineerings such as subway, tunnel, culvert, water conservancy
Rubber material used in waterstop.It can cause the chemical structure of rubber that the medium of irreversible change occurs, referred to as chemistry is rotten turbid
Property medium.When rubber product and chemical mediator contact, the decomposition of rubber and compounding agent is caused due to chemical action, and is generated
Chemical attack effect sometimes can also cause the uneven swelling of rubber.Keep rubber molecule disconnected into the chemical substance in rubber
It (is usually mostly that inorganic chemicals are water-soluble that phenomena such as splitting, dissolve and decomposing compounding agent, dissolve, dissolving out, which is all chemical mediator,
Liquid) generated while infiltration into vulcanizate.
Ordinary rubber such as NR, SBR, CR etc. are using temperature not high, in the lesser situation of concentration of medium, by appropriate
Acid and alkali-resistance cooperation, vulcanizate have the ability of certain resistance to common soda acid.The chemical mediator that oxidisability is extremely strong, corrosiveness is very big
(such as concentrated sulfuric acid, nitric acid, chromic acid), the then rubber for selecting the chemical stabilities such as fluorubber, butyl rubber good.But it is corrosion-resistant at present
Rubber material, higher cost, elasticity is not strong, not wear-resisting.Those skilled in the art, it would be highly desirable to which development cost is cheap, has excellent performance, bullet
Property good and wear-resisting high-elastic anticorrosive wear-resistant oil-resistant rubber material.
Summary of the invention
The object of the present invention is to provide a kind of high-elastic anticorrosive wear-resistant oil-resistant rubber materials.
A kind of high-elastic anticorrosive wear-resistant oil-resistant rubber material, is made of the component of following parts by weight:
It is nitrile rubber 137 ~ 145, MgO10 ~ 15, captax 2.5 ~ 3.5, thermoplastic polyurethane 35 ~ 47, polyvinyl chloride 7 ~ 23, hard
Resin acid 2.5 ~ 3.5, paraffin 1.0 ~ 1.5, carbon black N550 125 ~ 145, carbon black N330 55 ~ 63, paraffin oil 70 ~ 100, promotor
CZ1.0 ~ 1.5, promotor TRA 1.3 ~ 2.4, accelerant B Z 0.9 ~ 1.2, Vulcanization accelerator TMTD 1.0 ~ 1.5, antioxidant 4010NA
3.3 ~ 4.2, antioxidant BLE 1.5 ~ 2.3, silicone master batch 6.0 ~ 8.0, sulphur 1.2 ~ 1.8.
A kind of preparation method of high-elastic anticorrosive wear-resistant oil-resistant rubber material includes the following steps:
Step 1: permix: by load weighted nitrile rubber, carbon black N550 and carbon black N330, each one third parts by weight
In MgO and stearic acid investment mixer, then floating weight is opened in the mixing under 130 ± 5 DEG C of smelting temperature, opens overturning material
Mixture is routed up in storehouse, is transferred to open mill, and polyvinyl chloride and the thin logical clot of thermoplastic polyurethane is added, after parking cooling, then plus
Enter sulphur of half parts by weight etc. carry out be kneaded form preplasticizing glue；Step 2: being kneaded: refining glue and load weighted will be closed
The MgO and stearic acid and paraffin oil of each 2/3rds parts by weight, silicone master batch, half parts by weight sulphur and promote promotor
CZ, promotor TRA, accelerant B Z, Vulcanization accelerator TMTD, antioxidant 4010NA, antioxidant BLE, paraffin and paraffin oil, put into again
In mixer, under 90 ~ 100 DEG C of smelting temperature, smash in feed bin it is even, the time be 3 ~ 5min, the sizing material being kneaded is routed up
Feed bin be added to open mill packet roller smash it is even after, thin 2-3 times logical, thin logical roll spacing is adjusted to 0.6-0.8mm, then bottom sheet, and bottom sheet is thick
Degree is 6 ~ 10mm, to bubble-free bottom sheet again；Step 3: molding vulcanization: the sizing material after mixing being packed into die cavity, temperature 165 ± 5
DEG C, 6 ± 1min of time be compression molded into type to get rubber product on the vulcanizing press of 10 ~ 15MPa of pressure.
Further, the silicone master batch be by thermoplastic macromolecule resin, silicone powder, foaming agent, organically-modified silicone oil,
The blending of organic siliconresin antioxidant is made.
Beneficial effects of the present invention:
In order to improve the resistance to corrosive chemicals of rubber material, the rubber compounding of water resistance is taken.Chemical mediator is to rubber
Destruction is related with the reactive and selectivity of chemical mediator, also related with the chemical structure of rubber.Chemical mediator is to rubber
Destruction mainly there are two process: chemical mediator first to rubber internal penetration, then with the active Gene response in rubber, into
And cause the destruction of chemical bond and secondary bond in rubber macromolecule.Nitrile rubber is selected, is contained more stable to chemical mediator
Rubber molecule structure should have higher saturation degree, to reduce the content of activated double bonds, and active substituent group should be not present, or
Person is to make the reactive group in structure in the presence of cyano and stablize.Secondly, polyvinyl chloride is added, thermoplastic polyurethane increases
Intermolecular force makes strand arrangement closely reduce gap, such as orientation and crystallization to the greatest extent, can all improve rubber to change
Learn the stability of medium.Polyvinyl chloride and nitrile rubber, thermoplastic polyurethane, three's solubility parameters is close, has extraordinary
Compatibility.Polyvinyl chloride tool itself has good corrosion resistance, and the cost that can reduce material improves material ozone and aging resistance
Performance, the addition of thermoplastic polyurethane improve the wearability and high resiliency of rubber material.
Selected filler has the carbon black of chemical natural instincts, and when being incorporated paraffin, protection can be formed on rubber surface
Film, avoids chemical mediator from directly contacting with rubber surface, also there is certain etch-proof effect.Carbon black can be to reduce rubber in sulphur
Change the volume fraction in glue, facilitates the volume change for reducing product.
For nitrile rubber, because it has unsaturation and is easy the oxidation by ozone, to cause to prevent
The destruction in terms of ozone is protected, there are also the chain flexibility of its molecule is poor, the expansion rate of ozone-induced cracking is also than very fast, especially
When contact with oil, the related antiozonant of addition is easy to be extracted, to cause the damage capability of protection ozone
The decline of aspect is used in combination with resistance to extraction and the anti-aging agent of heat resistance, can be conducive to the oil resistant of vulcanized rubber with
Improvement in terms of heat resistance selects 4010NA and BLE to be used in combination, and the synergistic effect of the two is played with this, to oil resistant rubber
Ageing-resistant, oil resistant and heat resistance are improved.
The present invention compared with prior art the advantages of:
Common nitrile rubber belongs to a kind of oil resistant rubber of versatility, along with the increase of the content of acrylonitrile, its oil resistant
Property and heat resistance can be improved, but wearability, elasticity can but decline.Processing performance is also poor, is kneaded and has plasticated
Carry out relatively difficult, easy roll release.The physical strength of own is relatively low, by being cooperated the filling system of reinforcement, polychlorostyrene
The blending and modifying of ethylene and thermoplastic polyurethane, sulfurized nitrile rubber can just have the performance of physically better machinery, more
The significant raising for corrosion resistance, tensile property and wearability.
