Description
Technical field
The invention belongs to encapsulant field, be specifically related to the encapsulant of a kind of methanol gasoline resistant.
Background technology
In view of the gradually shortage of current petroleum resources and being gradually increased of environmental protection consciousness, clean environment firendly
The popularization of the energy and use are more and more universal, in automobile industry, also in the urgent need to finding alternative gasoline
Low stain and rich reserves for substitute fuel.
Compared to the gasoline commonly used at present and ethanol petrol, methanol fuel burns more in automobile engine
Add completely, benefit higher, blowdown is less, is the fuel of a kind of function admirable, mixes a definite proportion in the oil
The methanol of example, can play energy-conservation and drop oligosaprobic effect.Meanwhile, methanol abundance, can be by coal or sky
So waste such as gas, timber, can alleviate the contradiction that oil-poor area oil supply is not enough.Therefore, development first
Alcohol gasoline is the direction of the fuel such as automobile from now on.
But, methanol is a kind of excellent organic solvent, the material such as rubber, plastics to automobile oil supply system
Etc. having swelling and be full of cracks effect, the aging of material also can be accelerated.Research shows, alcohol fires with the mixing of gasoline
Expect that the swelling action to rubber, plastics is all stronger than single alcohol or gasoline, and the swelling action of methanol compares second
Alcohol is higher.This makes the rubber packing material used in gasoline and Gasohol at present cannot be used for first
Using in alcohol gasoline system, need to make improvements this, the present invention is studied this side up, proposes
A kind of feasible scheme.
Summary of the invention
For deficiency of the prior art, the invention provides the encapsulant of a kind of methanol gasoline resistant, cost
Low, swelling resistance is effective.
The present invention is achieved through the following technical solutions.
The encapsulant of a kind of methanol gasoline resistant, including the component of following weight proportion: fluorine-containing rubber 18～30%；
Ppta-pulp fibre 6～10%；Activator 18～25%；Fine particle calcium carbonate 15～21%；Magnesium oxide 3～8%；Filler
17～25%；Cross-linking agent 1～5%；Silane coupler 2～8%；Wherein, described fluorine-containing rubber is fluorinated volume
Fluorine-containing rubber more than 70%；Described ppta-pulp fibre is that aramid fiber is cleaved, formed after water mill
Ppta-pulp fibre；Described activator is one or more in active carbon white, titanate ester；Described fill out
Filling agent is one or more in Kaolin, calcium carbonate；Described cross-linking agent is silane coupling agent.
As further preferred component, including the component of following weight proportion: fluorine-containing rubber 23～26%；Virtue
Synthetic fibre pulp fibers 7～8%；Activator 21～23%；Fine particle calcium carbonate 18～20%；Magnesium oxide 4～5%；Filler 20～22%；

The most traditional electromotor encapsulant all uses the material that nitrile rubber and fiberfill are mixed,
For gasoline and the sealing of lubricating oil, but this kind of material methanol tolerant poor performance, corrode and deform big, persistency
Difference causes seal failure.
Therefore, compared with prior art, the method have the advantages that and the present invention relates to a kind of resistance to first
The encapsulant of alcohol gasoline, can be applicable to auto industry, oil, chemical industry and the field such as machinery, Aero-Space,
There is excellent oil resistant, methanol tolerant, swelling resistance character.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the invention will be further described.
The encapsulant of the methanol gasoline resistant in the present invention prepares in accordance with the following methods: (1) shredding: by proportioning

Encapsulant from the test result of above example it can be seen that in the present invention is in plurality of liquid
After immersion, still there is good tensile force and resilience force, and weightening finish, the ratio of thickening meet existing encapsulant
Standard, more excellent compared to common seal member material properties.Additionally, the material in above example is at methanol
After middle immersion and repeatedly immersion, rate of body weight gain and the rate that thickens show excellence, have good swelling resistance,
Wherein, the carboxymethyl cellulose that adds in embodiment 4～6, citric acid, the component such as starch, increase the most further
Material consolidation hot strength and anti-Swelling Capacity are added so that it is there is in methanol environment lower loss of tension
Rate and rate of body weight gain, thicken rate.
