Description
Technical field
The present invention relates to rubber materials, in particular to a kind of ethanol petrol resistant nitrile rubber sizing material and preparation method thereof.
Background technique
Nitrile rubber is a kind of preferable oil resistant rubber of heat resistance, and oil resistivity is fabulous, and wearability is higher, and heat resistance is preferable,
Bonding force is strong.The disadvantage is that lower temperature resistance is poor, ozone resistance is poor, insulation performance is inferior, and elasticity is slightly lower.Due to industrial expansion,
A kind of ethanol petrol resistant rubber size used at a lower temperature is needed, but the lower temperature resistance of fluorine glue is poor, low temperature is preferable
It is with high costs, therefore develop a kind of low temperature resistant, the low ethanol petrol resistant rubber size of production cost has considerable economic benefit
And social benefit.
Summary of the invention
The purpose of the present invention is to provide a kind of ethanol petrol resistant nitrile rubber sizing materials low temperature resistant, at low cost.
To achieve the above object, the present invention provides a kind of ethanol petrol resistant nitrile rubber sizing material and preparation method thereof,
Be characterized in that, be made of following components and parts by weight: 100 parts of NBR3250, it is fast squeeze out 120 parts of carbon black, 50 parts of MESAMOLL,
7 parts of activating agent, 2 parts of anti-aging agent RD, flowing 1.5 parts of dispersing agent, 3.5 parts of vulcanizing agent.
The activating agent is zinc oxide and stearic mixture.
The zinc oxide and stearic mass ratio are 5:2.
The vulcanizing agent is the mixture of sulphur, accelerant CZ and Vulcanization accelerator TMTD.
The sulphur, accelerant CZ and Vulcanization accelerator TMTD mass ratio are 3:3:1.
A kind of preparation method of ethanol petrol resistant nitrile rubber sizing material, which is characterized in that step are as follows: NBR3250 is thin logical
Pressing, roll spacing 1-2mm, 8~10min of pressing time, addition activating agent, anti-aging agent RD, flowing dispersing agent, 2~3mm of roll spacing, pressure
2~3min of time is closed, fast extrusion carbon black, MESAMOLL, 4~6mm of roll spacing, 13~15min of pressing time, addition vulcanization are added
Agent, 4~6mm of roll spacing, pressing time 2~3min, thin to lead to three times, 1~2mm of roll spacing, 3~4min of pressing time；Beat triangle bag six
Bottom sheet after a, 4~6mm of roll spacing, 3~4min of pressing time.
The activating agent is zinc oxide and stearic mixture.
The vulcanizing agent is the mixture of sulphur, accelerant CZ and Vulcanization accelerator TMTD.
NBR3250 of the present invention is raw rubber, is a kind of synthetic rubber as prepared by butadiene and acrylonitrile compolymer,
ACN (acrylonitrile) content is 41.5% in NBR3250, has better oil resistivity, while improving the cold tolerance of sizing material.
Fast extrusion carbon black of the present invention is filler, and the intensity and hardness and stress at definite elongation of sizing material can be improved.This hair
Lucid and lively extrusion content of carbon black is more than that 120 parts of meetings make to be formulated hardness increase, and lower than 120 parts meetings make to be formulated hardness reduction, are more than or small
Yu Douhui makes the gel content variation of formula, and gel content variation can make performance formula variation that can make incipient scorch or undercure.
MESAMOLL of the present invention is plasticizer, and the plasticity of sizing material can be improved, when reducing compound viscosity and being kneaded
Temperature improves dispersibility and Combination, improves the tensile strength and elongation of vulcanizate.The dosage of MESAMOLL is lower than 50 parts of meetings
Make to be formulated hardness increase, the meeting more than 50 parts makes to be formulated hardness reduction, more or less than the gel content variation that can all make formula, containing glue
Amount variation can make performance formula variation that can make incipient scorch or undercure.
Zinc oxide and stearic acid of the present invention are activating agent, and the sizing material degree of cross linking can be improved, and improve vulcanizate thermostabilization
Property, vulcanization time is reduced and shortened, curing efficiency is improved.Stearic acid and zinc oxide are used cooperatively, and play vulcanization accelerator,
Zinc oxide and stearic mass ratio can generate unnecessary waste when being greater than 5:2 parts, and zinc oxide and stearic mass ratio are small
It is easy to cause curingprocess rate unstable when 5:2 parts.
Anti-aging agent RD of the present invention be anti-aging agent, can be improved sizing material to heat and aoxidize caused by aging play it is splendid
Protective action.The dosage of anti-aging agent RD, which is 2 parts, to be made to be formulated anti ageing property raising, can generate the old of formula more or less than 2 parts
Change performance and high-temperature oil resistance performance change.
Flowing dispersing agent of the present invention is dispersing agent, and sizing material flow behavior can be improved, and improves the compatibility between sizing material
So that the processing performance of sizing material improves.It is that formula is made to have better dispersion when product that the dosage of flowing dispersing agent, which is 1.5,
Effect can generate the difference that will cause dispersion effect more or less than 1.5 parts, if amount easily causes product when being greater than 2 parts
It spits white.
Sulphur, accelerant CZ and Vulcanization accelerator TMTD of the present invention are vulcanizing agent, make the passing through of linear macromolecule of rubber
It learns crosslinked action and forms three-dimensional space network structure, after vulcanization, essence all occurs for the physical property of sizing material and other performances
Variation.For example vulcanizate heating is no longer flowed, insoluble in its good solvent, modulus and hardness are improved, and mechanical property improves, resistance to
Ageing properties and chemical stability raising etc..Sulphur, accelerant CZ and Vulcanization accelerator TMTD mass ratio of the present invention are that 3:3:1 can make to match
Square vulcanization crosslinking improves oil resistance.
The present invention selects the acrylonitrile comparision contents height of NBR3250 to have better oil resistance, and NBR3250 sizing material improves
High cost caused by fluorine glue is selected in the cold tolerance of sizing material and reduction, and the preferable MESAMOLL of compatibility is selected to be conducive to prevent
Only oil is extracted.Ethanol petrol resistant nitrile rubber sizing material of the present invention can satisfy using temperature in -40 DEG C of -120 DEG C of ranges
It is used under ethanol petrol environment, and cost is well below fluorine glue material, and can satisfy the low temperature that common fluorine glue is unable to satisfy
It is required that.
NBR3250 pressing is first added in ethanol petrol resistant nitrile rubber sizing material preparation process of the present invention makes NBR3250
Tough high resiliency state is transformed into flexibility and rich in plastic state, after first add activating agent, anti-aging agent and dispersing agent pressure
It closes, rear extrusion carbon black, the MESAMOLL stage agent addition fastly of being added can be improved melting efficiency and increase its uniformity, be eventually adding vulcanizing agent
Sizing material incipient scorch is not will cause.
Obdurability is relatively high before not pressing because of NBR3250 raw rubber need to need roll spacing relatively thin state could be transformed into softness
Property.Raw rubber has had opposite flexibility when addition activating agent, anti-aging agent and dispersing agent, and roll spacing can slightly be beaten makes powder a little louder
Material can be mixed with raw rubber faster.Be added it is fast squeeze out carbon black, MESAMOLL the two materials are measured compare in formula
Greatly, roll spacing will be beaten could more preferably mix with raw rubber faster a little louder.It is eventually adding vulcanizer not and will cause sizing material incipient scorch.
It can be obtained by resistance to liquid energy and freezing test result, the resulting ethanol petrol resistant butyronitrile rubber of technical solution of the present invention
Glue sizing material resistance to liquid energy and cold tolerance are superior to 80 degree of fluorine glue of outsourcing, and cost is relatively low.
