Abstract
The present invention discloses a kind of encapsulant, calculates according to the mass fraction, including following component：200 250 parts of silicon rubber, 250 300 parts of fluororesin, 100 150 parts of vulcanization rubber, 150 200 parts of ethylene propylene diene rubbers, 10 15 parts of stearoyl lactates, 10 12 parts of titanium dioxide, 58 parts of potassium hydroxide, 12 15 parts of magnesium hydroxides, 8 10 parts of acrylic anhydrides, 68 parts of phenyl isocyanates, 10 15 parts of dimethyl fumarates, 58 parts of dibenzoyl peroxides, 68 parts of tert-butyl lithiums, 78 parts of silicon nitrides, 5 10 parts of silica flours.The mechanical strength of the encapsulant is high, coefficient of friction is low（For 0.20 0.22）, antiwear property it is strong, in high temperature（It can be worked in 200 DEG C of occasions）High pressure（400MPa pressure can be born）Service life is grown under condition of work.
Description
Technical field
The present invention relates to the technical field of seal, more particularly to a kind of encapsulant.
Background technology
Sealing article is all kinds of mechanical important foundation elements, and almost all of industrial department all be unable to do without it.Sealing member
How is the quality of part, is directly connected to the service life and operating reliability of machine.If seal is with low quality, gently then bring
Loss and trouble, it is heavy then serious accident can be caused.Especially under the high environment of operating pressure, load that sealing ring is born compared with
Greatly, through being commonly encountered seal damaged condition in equipment running process, some seals can only use 1-2 individual month, even more
The short time, it is necessary to change, the trouble that the continuous production to enterprise is brought.Therefore, at present can be in high pressure there is an urgent need to one kind
The encapsulant of longer cycle is used under environment.
The content of the invention
It is an object of the invention to solve shortcoming and defect present in above-mentioned prior art, there is provided a kind of encapsulant,
The mechanical strength of the encapsulant is high, coefficient of friction is low（For 0.20-0.22）, antiwear property it is strong, in high temperature（Can be 200
The work of DEG C occasion）High pressure（400MPa pressure can be born）Service life is grown under condition of work.
Realize that the technical solution adopted for the present invention to solve the technical problems is：A kind of encapsulant, according to the mass fraction
Calculate, including following component：200-250 part silicon rubber, 250-300 part fluororesin, 100-150 parts vulcanization rubber, 150-200 parts three
First EP rubbers, 10-15 part stearoyl lactates, 10-12 part titanium dioxide, 5-8 part potassium hydroxide, 12-15 part magnesium hydroxides,
8-10 part acrylic anhydrides, 6-8 part phenyl isocyanates, 10-15 part dimethyl fumarates, 5-8 part dibenzoyl peroxides, 6-8 parts
Tert-butyl lithium, 7-8 part silicon nitrides, 5-10 part silica flours.
Further, the number of each component is：200 parts of silicon rubber, 250 parts of fluororesin, 100 parts of vulcanization rubber, 150 part three
First EP rubbers, 10 parts of stearoyl lactates, 10 parts of titanium dioxide, 5 parts of potassium hydroxide, 12 parts of magnesium hydroxides, 8 parts of acrylic acid
Acid anhydride, 6 parts of phenyl isocyanates, 10 parts of dimethyl fumarates, 5 parts of dibenzoyl peroxides, 6 parts of tert-butyl lithiums, 7 parts of silicon nitrides, 5 parts
Silica flour.
Further, the number of each component is：250 parts of silicon rubber, 300 parts of fluororesin, 150 parts of vulcanization rubber, 200 part three
First EP rubbers, 15 parts of stearoyl lactates, 12 parts of titanium dioxide, 8 parts of potassium hydroxide, 15 parts of magnesium hydroxides, 10 parts of acrylic acid
Acid anhydride, 8 parts of phenyl isocyanates, 15 parts of dimethyl fumarates, 8 parts of dibenzoyl peroxides, 8 parts of tert-butyl lithiums, 8 parts of silicon nitrides, 10
Part silica flour.
In summary, the mechanical strength of encapsulant of the invention is high, coefficient of friction is low（For 0.20-0.22）, it is wear-resistant
Ability is strong, in high temperature（It can be worked in 200 DEG C of occasions）High pressure（400MPa pressure can be born）Service life under condition of work
It is long.
