Abstract
The invention belongs to the technical field of rubber, and particularly relates to low-temperature resistant fluororubber for an oil seal. The low-temperature resistant fluororubber comprises the following components in parts by weight: 0-100 parts of fluororubber VPL85540, 0-100 parts of fluororubber LTFE6400, 0.5-1.5 parts of HT290, 10-40 parts of 10WC10222, 0-40 parts of N990, 0-10 parts of N774, 3-4 parts of TAIC-70 and 1.2-2 parts of 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane-45. The fluororubber provided by the invention has excellent low-temperature resistance while guaranteeing resistance to high temperature and oil; the low-temperature retraction temperature TR10 can reach minus 40 DEG C; by adopting the rubber provided by the invention to manufacture an oil seal of a damper, the oil seal can be used for a long time at (-40)-(+200) DEG C.
Description
Technical field
The present invention relates to a kind of oil seal for shock damper viton, relate in particular to a kind of low temperature resistant oil sealing viton, belong to rubber technology field.
Background technology
In vibroshock reciprocating oil seal industry, the main elastomeric material using is NBR at present, NBR is different according to ACN content, can meet different use temperature scopes, as the NBR of low ACN content can meet within the scope of-40～+ 100 ℃, use, the NBR of middle high ACN content can meet use within the scope of-25～+ 120 ℃.But along with automobile industry is just towards the fast development of high speed, comfortableization, wider compartmentation, vibroshock is had higher requirement.In present many vibroshock applying working conditions, require oil sealing can be at higher temperature life-time service, as more than 160 ℃ and 160 ℃, but also it is oil-proof to guarantee that vibroshock starts under ℃ environment of low temperature-40, and the practical application experience of NBR is told us, surpass the temperature condition of 120 ℃, its physical property has declined much, almost loses use function, and the good HNBR of resistance to elevated temperatures also only can meet within the scope of oil sealing-30～+ 150 ℃ and uses.
If meet oil sealing life-time service and oil resistant, high abrasion resistance under higher than 160 ℃ of high temperature, can select viton, it is heat-resisting, oil resistant, media-resistant, wear resistance are all better than other rubber, can be at 200 ℃ life-time service.But common viton lower temperature resistance is poor, 26 type viton low temperature retraction temperature T R10 are generally at-17 ℃, 246 type viton low temperature retraction temperature T R10 are generally at-14 ℃, traditional viton resistance to low temperature is very poor obviously, temperature is below-20 ℃ time, viton follows the string completely, loss of seal performance.Therefore with common viton making oil sealing, can not meet vibroshock and start oil tight requirement under ℃ environment of low temperature-40.
Summary of the invention
For the deficiencies in the prior art, the present invention provides a kind of low temperature resistant and still keep oil sealing viton well high temperature resistant, oil resistance for solving the problems of the technologies described above.
A kind of low temperature resistant oil sealing viton of the present invention, its component is counted by weight: two 2 5-45 of the viton VPL85540 of 0～100 part, the viton LTFE6400 of 0～100 part, the HT290 of 0.5～1.5 part, the 10WC10222 of 10～40 parts, the N990, the N774 of 0～10 part, the TAIC-70 of 3～4 parts of 0～40 part and 1.2～2 parts.
Further, a kind of low temperature resistant oil sealing is preferably by weight by the component of viton: the viton VPL85540 of 0～100 part, the viton LTFE6400 of 0～100 part, 1 part of HT290, the 10WC10222 of 20～40 parts:, the N990 of 0～30 part, the N774 of 0～10 part, the TAIC-70 of 3.2～3.8 parts and 1.5～2 parts two 2 5-45.
