7 parts of lignin, 2-4 parts of lubricants, 11-15 parts of polyethylene glycol, 2-7 parts of diatomite, 1-2 parts of olive oil, it is close made from the invention
Seal has good cold resistance and temperature difference endurance, not easy to crack in temperature fluctuation, not embrittlement, but motor is close
Seal also needs to ensure that intentional high temperature resistance, the application high temperature resistance are weaker.
Chinese Patent Application No. 201510105783.4 discloses a kind of low-temperature-resistant elastic body containing fluorine and preparation method thereof, institute
Fluoroelastomer is stated to be mediated, be kneaded by following mass fraction group lease making heat：100 parts of fluorubber, 0~30 part of acid absorbent, hydrogen
0~35 part of calcium oxide, 0~50 part of reinforced filling, 0~10 part of plasticizer, 0.5~5 part of vulcanizing agent, 0~5 part of organic wax promote
0.2~2 part of agent, 1~10 part of (more) amino silane, 1~30 part of silicone oil of carboxyl, 1~10 part of multifunctional assistant LCA.The invention is logical
It crosses and adds a kind of silicone oil of carboxyl and active amino silane, while coordinating a kind of multifunctional assistant LCA, make its black brittleness temperature
There are one preferably floating downward, but the inorganic filler in raw material is on the high side, influences the mechanical performance of product.
Invention content
In view of this, in view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of special fluorubber electricity of nuclear power
Secret seal, the fluorubber electricity secret seal high mechanical strength, oil resistance is excellent under high temperature, is suitable for nuclear ship motor
On.
In order to achieve the above objectives, the present invention uses following technical scheme：
A kind of special fluorubber electricity secret seal of nuclear power, includes the raw material of following parts by weight：85-90 parts of fluorubber,
1-2 parts of 5-8 parts of acid absorbent, 2-5 parts of composite vulcanizing agent, 8-10 parts of reinforcing agent and auxiliary agent.
Further, the fluorubber is fluororubber 246 3, fluororubber 26 02 and fluororubber 26 03 by weight 0.5-
1.5：0.5-1.5：1 mixes.
Further, the acid absorbent is calcium oxide and magnesia by weight 0.5-1.5：1 mixes.
Further, the composite vulcanizing agent is bisphenol AF, benzyltriphenylphosphonium chloride, No. 3 vulcanizing agents and No. 5 vulcanizing agents
2-4 by weight：2-4：2-4：1 mixes.
Further, the reinforcing agent is carbon black N990.
Further, the auxiliary agent is palm wax.
A kind of preparation method of the special fluorubber electricity secret seal of nuclear power, includes the following steps：
(1) it premixes：Acid absorbent, composite vulcanizing agent, reinforcing agent and auxiliary agent are uniformly mixed, pre-composition is obtained；
(2) rubber compounding：Fluorubber is added in open mill, is slow added into pre-composition, then beats triangle bag 3-5 times,
Blanking is thin 5-8 times logical, bottom sheet.
(3) vulcanize：
One step cure：It is carried out on vulcanizing press, curing temperature is 160-165 DEG C, oil pressure 14-16MPa, when vulcanization
Between be 8-12min；
Post vulcanization：It is carried out in insulating box, sulfidation is followed successively by Vulcanization terminates up to product.
Further, open mill roller temperature is 40-60 DEG C in the step (2).
Further, thin logical roll spacing is 0.5-1.0mm in the step (2).
The beneficial effects of the invention are as follows：
1, the present invention is in order to enhance the comprehensive performance of the special fluorubber electricity secret seal of nuclear power, from raw material and preparation method
On improved, the hardness of the product of preparation is 65-75 degree, tensile strength 15-18MPa, compression set rate 25-
29%, high-temperature oil resistance performance is good, excellent combination property.
2, the fluorubber that the present invention uses mixes for fluororubber 246 3, fluororubber 26 02 and fluororubber 26 03, this
Fluorine content is different in three kinds of fluorubber, and heat resistance, resistant of high or low temperature, electrical property and mechanical performance respectively have feature, by this three
Kind fluorubber is used in mixed way, and can be had complementary advantages, and is acted synergistically, and the product of preparation has the chemical stability of height, resistance to oil
Base oil class, double lipids oil, silicic acid lipid oil, inorganic acid resistance, resistant to many organic solvent, resistance to inorganic solvent, drug etc.；And compression resistant
The performance that is permanently deformed is good, and after 246 type fluorine glue are added, its wearability greatly improves 226 type fluorine glue；In addition product is weather-proof
Property, ozone resistance are also improved largely, and vulcanizate is after natural aging in 10 years, moreover it is possible to keep preferable performance；Product
Service life reached 15000h or more at 200 DEG C, can be used for a long time at a high temperature of 250 DEG C, even if also may be used at 300 DEG C
Longer use, limiting temperature reach 350 DEG C or more.
When individually using calcium oxide as acid absorbent, the good physical performance of product is prepared, but anti-aging property is poor, and oxygen
The characteristics of anti-aging property for changing magnesium sizing material is excellent, therefore the present invention is directed to three kinds of fluorubber in raw material, with calcium oxide and oxidation
The mixing of magnesium can effectively neutralize the hydrogen fluoride being precipitated during vulcanizable fluororubber, and the object of the product prepared as acid absorbent
Rationality can be excellent with processing performance, avoids the damage to mold.
The vulcanizing agent that the present invention uses is composite vulcanizing agent, by bisphenol AF, benzyltriphenylphosphonium chloride, No. 3 vulcanizing agents and 5
Number vulcanizing agent mixes, and the crosslink density of product is high, and cross-linked network is fairly perfect, and interface bond strength is stronger, product
Excellent in mechanical performance.
Reinforcing agent is carbon black N990, and carbon black N990 has following features in the processing of fluorubber：(1) raw in mixing process
Heat is small, and processing temperature is low；(2) grain size of carbon black N990 is big, and specific surface area is small, is particularly easy to rubber mix, and mixing time
It is short, moreover it is possible to reduce power consumption；(3) sizing material viscosity is not increased, rubber mobility is good, is conducive to the complicated rubber part of processing；
(4) sizing material extrusion performance is good, squeezes out soon, and expansion rate is small, is convenient for size Control；(5) the high filling quality of carbon black N990 does not influence
The tackness of rubber, does not also influence curingprocess rate, and under high filler loading capacity, the gap of sizing material is reduced to minimum, to have well
The performance of air-tightness, vacuum-resistant is more preferable.Therefore using carbon black N990 as reinforcing agent, properties of product, such as heat-resisting can be substantially improved
Property, hardness and compression set etc..
It also added auxiliary agent in the special fluorubber electricity secret seal of nuclear power of the present invention, auxiliary agent uses palm wax, is being kneaded
The surface of vulcanized rubber can be moved to, protective film is formed, the appearance of product can be improved, there is blast effect, in addition also rise
To protection and anti-aging effect.
3, in the preparation process of product, the magnesia in acid absorbent and No. 3 vulcanizing agents is adhered on roller in order to prevent
And magnesia is not easy to be mixed into the problems in sizing material, is first uniformly mixed acid absorbent, vulcanizing agent, reinforcing agent and auxiliary agent, is premixed
Object, then carry out rubber compounding.
Sulfidation uses post vulcanization method, wherein (1) one step cure：Purpose is the pressure by model and vulcanizing press
The effect of power and temperature, makes product tentatively shape, and obtains necessary shape；(2) post vulcanization：Post vulcanization is in electric heating air blast
It is carried out in insulating box, can further improve the crosslink density of vulcanizate, its stress at definite elongation is made to increase, elongation and the permanent change of compression
Shape reduces.
