Description
Technical field
The present invention relates to macromolecular material, specifically is a kind of heat-resisting Cold-proof oilproof sizing material.
Background technology
Aircraft tyre all is in high, to use under pressure, the high-speed big load condition, and the intensity of tire and cf-must satisfy these harsh working conditionss.The sizing material that particularly uses in the sealing-ring of Boeing-737-700/800 aircraft nose wheel requires both to have the performance of high-and low-temperature resistance, oil resistant, anti-weather, has the characteristics of life-span length, good sealing effect again.Seek good like this sizing material, caused extensive concern.
Summary of the invention
The objective of the invention is to provide a kind of not only heat-resisting, cold-resistant but also oil resistant and the superior sizing material of anti-weather, particularly heat-resistant oil performance, this sizing material quality change in deep fat is little, pull apart that the elongation reduced rate is little, compression set is little, and the low temperature cold tolerance is good.
The object of the invention realizes through following technical proposals:
A kind of heat-resisting, cold-resistant, oil resistant sizing material, form by following raw material by weight:
Described TM monex TD is the thiuram type accelerator tetramethyl-thiuram disulfide; Altax is the thiazole accelerator dibenzothiazole disulfide; N330 is a high abrasion furnace black(HAF); DBP is a Witcizer 300; DOP is a DOP; Antioxidant D is the N-PBNA; Antioxidant 4010NA is N-sec.-propyl-N-diphenyl-para-phenylene diamine.
The preparation method of above-mentioned sizing material comprises the steps:
(1) above-mentioned X 050, hard(carbon)black, anti-aging agent, promoting agent, softening agent, promotor by weight dropped in the rubber internal mixer mixing, under 120～130 ℃ with 20 to 30r/min rotating speed through 4～6 minutes mixing rubber unvulcanizate A that obtain;
(2) zinc oxide or nano zine oxide and above-mentioned rubber unvulcanizate A is mixed, in rubber internal mixer under 105 ℃ with 15 to 20r/min rotating speed through 3～5 minutes mixing processing.
Adopt sizing material that above-mentioned prescription and compounding process make through performance test, its The performance test results such as following table:
Performance test shows, this sizing material quality change in deep fat is little, pull apart that the elongation reduced rate is little, compression set is little, and the low temperature cold tolerance is good.
This sizing material is selected for use molecular chain to contain the chlorine atomic radical and is had the polar X 050 as main material; Adopt the zinc oxide vulcanization system; Form by zinc oxide or nano zine oxide, Natural manganese dioxide and Triple Pressed Stearic Acid, add the coke burning performance that TM monex TD and altax improve sizing material simultaneously; Through add high-low temperature resistant, compression heat generation is low, be out of shape the high structure furnace treated black little, that stress at definite elongation is higher or with general carbon black or semi-reinforcing hydrocarbon black and with or single use wherein a kind of; Adding ester plasticizer makes sizing material have good low temperature, oil resistance; Though the ageing-resistant performance of neoprene latex is better; But because the interaction energy of heat, light, oxygen makes the X 050 oxygenolysis; Cause physical and mechanical properties to descend; In prescription, add amines antioxidants or p phenylenediamine type antioxidant and protection wax and the usefulness that heat, light, oxygen is had good protective effect, form protective membrane, strengthen the provide protection and the oil resistance of anti-ozone anti-aging agent and can obtain high-caliber quiet dynamic ozone protective effect on the cross-linked rubber surface.Thereby this sizing material is not only heat-resisting, cold-resistant, oil resistant; Also special heat resistant oils; Can be used for civil aviation aircraft nose wheel wheel rim and can adapt in 120# gasoline and benzol mixture, YH-10 transformer oil, PR-3 oil, the multiple deep fat environment of 1# standard wet goods, have heat-resisting, cold-resistant, oil resistant simultaneously and good anti-weather performance is arranged with sealing-ring.Can be applicable in the sealing-ring of Boeing-737-700/800 aircraft nose wheel, to satisfy the civil aviation aircraft must have high-low temperature resistant, oil resistant, anti-weather, long service life, good sealing effect to sealing article needs.
