Abstract

The present invention discloses an oil resistance and abrasion resistance rubber, wherein the rubber comprises the following materials: a natural rubber, a tread rubber, zinc oxide, stearic acid, carbon black N330, paraffin, coumarone, sulfur, asphalt, 2,2-di(2-thienyl)glycolic acid methyl ester, dimethyl 4-nitrophthalate, 3,5-dimethyl-4-methoxy-2-pyridinemethanol, an anti-aging agent and an accelerator. Compared with the oil resistance and abrasion resistance rubber in the prior art, the oil resistance and abrasion resistance rubber of the present invention has the following advantages that: the 2,2-di(2-thienyl)glycolic acid methyl ester, the dimethyl 4-nitrophthalate, and the 3,5-dimethyl-4-methoxy-2-pyridinemethanol are added to the formula, such that the oil resistance of the natural rubber is increased to 6-7%.

Description

The oil resistant abrasive rubber
Technical field
The present invention relates to rubber, particularly for the oil resistant abrasive rubber of pipe liner.
Background technology
In the pipeline transportation in oil field, the medium transported is for the mixture of oil and ore in sand form, therefore its pipe liner rubber used normally contains the natural rubber of tread rubber, although above-mentioned rubber has wear resisting property, but its oil-proofness is very poor, its oil resistance can only reach more than 15%.
Summary of the invention
Technical problem to be solved by this invention is to provide the oil resistant abrasive rubber that a kind of oil resistance reaches 6-7%.
The technical scheme of technical solution problem of the present invention is: the oil resistant abrasive rubber, contain following material and weight part:
Figure BDA0000182125611
Figure BDA0000182125612
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 formula, adding 2,2-dithienyl methyl glycolate, 4-nitrophthalic acid dimethyl ester, 4-methoxyl group-3,5-dimethyl-2-4-hydroxymethylpiperidine, make the oil resistance of natural rubber bring up to 6-7%.
Embodiment:
The present invention is described in detail below in conjunction with embodiment.
Embodiment 1:
Figure BDA0000182125614
Embodiment 2:
Figure BDA0000182125615
Embodiment 3
Figure BDA0000182125616
Figure BDA0000182125617
Oil resistance of the present invention detects according to ASTM D 471 standards, and unit is %;
The oil resistance of embodiment 1,2,3 (rate of expansion after the oil immersion bubble) is respectively 6.3%, 6.8%, 6.7%.
