Abstract
The invention discloses a high temperature-resistant rubber resisting a temperature of 140 DEG C. The high temperature-resistant rubber contains nitrile rubber, zinc oxide, stearic acid, carbon black N330, carbon black N660, paraffin oil, paraffin, sulfur, 2-deoxy-2,2-difluoro-pentafuranosyl-1-keto-3,5-dibenzoate, 1-(2-dimethylaminoethyl)-1H-5-mercapto-tetrazole, an antiager and an accelerator. Compared with the prior art, the high temperature-resistant rubber has the advantages that through utilization of 2-deoxy-2,2-difluoro-pentafuranosyl-1-keto-3,5-dibenzoate and 1-(2-dimethylaminoethyl)-1H-5-mercapto-tetrazole, a heat-resistance temperature of nitrile rubber is improved to a temperature of 140 to 150 DEG C.
Description
Technical field
The present invention relates to rubber, particularly for pipe liner anti-140 the degree super heated rubber.
Background technology
Paracril has good water-fast, oil-proofness, is usually used in the lining of pipeline, but the temperature range of its use is-40 to 120 ℃, can not be applicable to the transportation of liquid more than 140 ℃.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high-temperature resistant rubber that temperature is 140 ℃ of transport of liquid that is applicable to.
The technical scheme of technical solution problem of the present invention is: the super heated rubber of anti-140 degree, contain following material and weight part:
The model of described paracril is 3365E.
Described anti-aging agent is: 2,2,4 trimethyl 1,2 dihydroquinoline polymer, anti-aging agent RD.
Described promotor is: 4-4'-dimorpholinyl disulfide (DTDM)
Preparation method of the present invention is identical with the preparation method of existing rubber.
The present invention compared with prior art, by in formula, adding 2-deoxidation-2,2 two fluoro-penta furanoses-1-ketone-3,5-dibenzoate, 1-(2-dimethyl aminoethyl)-1H-5-sulfydryl-tetrazole, make the heat resisting temperature of paracril bring up to 140-150 ℃.
Embodiment:
The present invention is described in detail below in conjunction with embodiment.
Described paraffin oil is produced by Wucheng County, Shandong Province one sail rubberization company limited.
Paraffin is by the auspicious rubber chemicals production of Hengshui space.
