Abstract
The present invention relates to a high temperature resistant low voltage variable light-colored acrylonitrile-butadiene rubber formula for a skeleton oil seal. The formula comprises the following compounds: acrylonitrile-butadiene rubber, zinc oxide, alkaline white carbon, a silane coupling agent Si-69, stearic acid, sulfur, a promoter TMTD, a promoter CZ, a promoter DTDM, an antioxidant 2246, an antioxidant MB, an antioxidant MMBI-70, and TP-759. According to the rubber provided by the present invention, hardness variation is 3, and a change rate of elongation is -11.6% at 125 DEG C for 72 hours in an experiment. A type voltage variation (25% compression) is 16 at 100 DEG C for 24 hours.
Description
Technical field
The present invention relates to rubber technology formulation art, particularly to shoal look paracril formula for the high temperature resistant low pressure of outside framework oil seal.
Background technology
Along with the fast development of railway systems, railway freight-car oil sealing receives the concern of more and more oil sealing manufacturer as important safety parts of train.White carbon black is compared with carbon black, high with metlbond intensity, and ageing-resistant performance is good, and vulcanization rate is slow, and pressure is deteriorated, and reinforcement is poor.Along with going deep into of research, the application of white carbon black gets more and more, and has had experiment to confirm, has applied white carbon black, can reduce tire drag 20% in tire, so white carbon black has been widely used in manufacturing green tire.Outside framework oil seal is pressing, rubber vulcanization speed is needed to want fast, the words that common white carbon black adds in a large number there will be serious sulfuration and postpone, vulcanization rate just causes making its widespread use in oil sealing slowly, if it is fast to invent a kind of vulcanization rate, high temperature resistant low pressure becomes, and the light butadiene-acrylonitrile rubber formula high with metlbond intensity, will make white carbon black widely apply in oil seal product.
Summary of the invention
A kind of high temperature resistant low pressure for outside framework oil seal is the object of the present invention is to provide to shoal look paracril formula, main purpose improves the heat resistant performance of light butadiene-acrylonitrile rubber, reduce pressure to become, improve sealing property and the work-ing life of oil sealing, ensure its security.
Technical scheme of the present invention is:
High temperature resistant low pressure for outside framework oil seal shoals a look paracril formula, it is characterized in that component and massfraction as follows: paracril 100 parts, 3 ~ 10 parts, zinc oxide; Stearic acid 1 ~ 6 part; Sulphur 0.2-1.5; Vulcanization accelerator TMTD 0.5 ~ 2.5 part; Accelerant CZ 1 ~ 3 part; Vulkacit D TDM0.5 ~ 2.5 part; Antioxidant MB 0.5 ~ 3.5 part; Antioxidant 2246 0.5 ~ 3.5 part; Anti-aging agent MMBI-700.5 ~ 2 part; Softening agent TP-7595 ~ 15 part; Alkalescence white carbon black 40 ~ 70 parts; Silane coupling agent Si-691 ~ 3 part.
The invention has the beneficial effects as follows:
High temperature resistant low pressure for outside framework oil seal of the present invention shoals look paracril at 125 DEG C, and under 72 hours experiment conditions, changes in hardness is 3, and elongation change rate is-11.6%.100 DEG C, it is 16 that 24hA type pressure becomes (boil down to 25%).
High temperature resistant low pressure for outside framework oil seal of the present invention shoals look paracril vulcanization rate soon, and high temperature resistant low pressure becomes, and the light butadiene-acrylonitrile rubber formula high with metlbond intensity, will make white carbon black widely apply in oil seal product.
High temperature resistant low pressure for the outside framework oil seal of the present invention look paracril that shoals improves the heat resistant performance of light butadiene-acrylonitrile rubber, reduces pressure and becomes, improve sealing property and the work-ing life of oil sealing, ensure its security.
