Abstract
The invention relates to the field of rubber, in particular to fluororubber which comprises the following components by mass: 100 parts of fluororubber 2602, 3 parts of an acid-acceptor, 10 parts of spraying carbon black, 2 parts of a vulcanizing machine, 1 part of a vulcanizing agent, 2.5 parts of a release agent and 2 parts of STR anti-tear resin. According to the fluororubber and a preparation method thereof, the acid-acceptor is added in the formula to remove acidic materials inside all raw materials, and besides, the STR anti-tear resin is added to improve the anti-tear capability of the fluororubber; in the preparation process of the fluororubber, secondary vulcanizing is adopted to improve the mechanical property and the compression set of the fluororubber.
Description
Technical field
The present invention relates to rubber materials, especially a kind of viton and preparation method thereof.
Background technology
Although existing viton has high temperature resistant, resistance to chemical attack, oil resistant, the feature such as ageing-resistant, easily there is tearing the situations such as fracture in its poor processability, have a strong impact on use range in process of manufacture; Resistance to low temperature is poor.And the fraction defective produced in production process is high, tooling cost is caused to increase, expensive.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology and provide a kind of formula rationally, technique is simple, has viton of stronger mechanical property and preparation method thereof.
In order to achieve the above object, a kind of viton designed by the present invention, it comprises fluororubber 26 02, acid-acceptor, spray carbon black, vulcanizer, vulcanization aid, releasing agent and STR anti tear resin, and wherein the mass fraction of each component is: 100 parts of fluororubber 26s, 02,3 parts of acid-acceptors, 10 parts of spray carbon blacks, 2 parts of vulcanizing agents, 1 part of vulcanization aid, 2.5 parts of releasing agents, 2 parts of STR anti tear resins.
A kind of preparation method of viton, first each component is taken by formula ratio, after fluororubber 26 02 on a mill until thin-pass bag roller, add releasing agent, spray carbon black equably again, suffer all and add acid-acceptor again after powder and STR anti tear mixed with resin is even, finally adding vulcanizing agent and vulcanization aid, after mixing, park revulcanization after 8 hours, answering control roller temperature below 60 degree when refining glue; Sulfidizing is Di-cure method, and the temperature of primary vulcanization is 165-170 DEG C, continues 10 minutes, and the temperature of second time sulfuration is 200 DEG C, continues 8 hours.
Viton that the present invention obtains and preparation method thereof, acid-acceptor is added in formula, absorb the acidic substance of each raw material inside in formula, add STR anti tear resin simultaneously, to improve the lear energy of viton, and in preparation process, adopting post cure, the object of post cure is mechanical property in order to improve viton and compression set.
Mould structure is avoided the appearance of wedge angle, corner angle in viton preparing product process as far as possible, reduce the situation that goods are torn.
Embodiment
The present invention is further described by the following embodiment.
Embodiment 1:
A kind of viton that the present embodiment describes, it comprises fluororubber 26 02, acid-acceptor, spray carbon black, vulcanizer, vulcanization aid, releasing agent and STR anti tear resin, and wherein the mass fraction of each component is: 100 parts of fluororubber 26s, 02,3 parts of acid-acceptors, 10 parts of spray carbon blacks, 2 parts of vulcanizing agents, 1 part of vulcanization aid, 2.5 parts of releasing agents, 2 parts of STR anti tear resins.
A kind of preparation method of viton, first each component is taken by formula ratio, after fluororubber 26 02 on a mill until thin-pass bag roller, add releasing agent, spray carbon black equably again, suffer all and add acid-acceptor again after powder and STR anti tear mixed with resin is even, finally adding vulcanizing agent and vulcanization aid, after mixing, park revulcanization after 8 hours, answering control roller temperature below 60 degree when refining glue; Sulfidizing is Di-cure method, and the temperature of primary vulcanization is 165-170 DEG C, continues 10 minutes, and the temperature of second time sulfuration is 200 DEG C, continues 8 hours.
