Description
Technical field
The invention belongs to rubber materials, in particular to a kind of high temperature resistant high durable braking sealing EPDM sizing material and its preparation
Method.
Background technique
With the development of the automobile industry, universal and speed the raising of car, the country proposes the quality of brake system of car
Increasingly higher demands are gone out.Because automobile is braked frequently when running at high speed, a large amount of frictional heat generation is bound to cause braking system
Temperature of uniting increases.When temperature is more than the boiling point of brake fluid, brake fluid will evaporate, and steam is formed in braking system, and having can
Air-resistance phenomenon can be generated, so as to cause brake failure；It is also required that brake fluid has suitable viscosity and good low temperature (- 40
DEG C) mobility, with guarantee at various temperatures, can quickly and accurately transmit pressure, it is ensured that braking system it is safe and reliable.At present
Common higher boiling brake fluid has DOT3, DOT4 and DOT5 in the world.Wherein 205 DEG C of the boils up till of DOT3, DOT4 and DOT5
Boiling point it is higher.All these conditions require that braking sealing class rubber should have broader temperature resistant range.
In order to constantly meet the requirement of client it is necessary to have developing broader -40 DEG C -150 DEG C of temperature resistant range, at the same it is durable
The braking sealing sizing material of function admirable.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of high durable braking sealing EPDM sizing material of high temperature resistant, having makes
With under environment the characteristics of high-low temperature resistant aging, resistance to braking fluid, long service life.
To achieve the above object, the technical scheme is that a kind of high durable braking sealing EPDM sizing material of high temperature resistant,
It is made of following components in percentage by weight:
Preferably, the high durable braking sealing EPDM sizing material of the high temperature resistant, is made of following components in percentage by weight:
Preferably, the ethylene-propylene diene copolymer rubber raw rubber trade mark is 4045M.It is manufactured by Mitsui.
Preferably, the carbon black is rich Austria N550.
Preferably, the T16 that the softening plasticizer is H&R.
Preferably, the vulcanizing agent is the peroxide vulcanizing agent of Japan.
Preferably, the ratio of the carbon black and ethylene propylene diene rubber is at least 0.7: 0.95.It can guarantee in rubber in this way
Meeting improves process industrial art performance on the basis of performance.
The present invention also provides the preparation methods of the high durable braking sealing EPDM sizing material of the high temperature resistant, successively include following
Step:
(1) it stocks up: according to the proportion, ethylene propylene diene rubber, carbon black, softening plasticizer, activating agent being weighed respectively
After be mixed to form ingredient A, after vulcanizing agent is weighed formed ingredient B；
(2) first of mixing: hammer is mentioned after ingredient A is put into mixer mixing 60~90 seconds and is cleaned, then hammer is kneaded 60
It mentions within~90 seconds hammer again to clean, 140~150 DEG C of temperature, then hammer is kneaded discharging in 60~80 seconds, 150~170 DEG C of temperature, arrives
Rubber compound A is made in slice on cutting machine；
(3) second is kneaded: second being kneaded rubber compound B obtained and is put into mixer mixing 30~40 seconds, is then existed
It is dumped into slice on cutting machine after continuing mixing after cleaning 30~50 seconds, completes preparation.
It in (2) and (3) step, is kneaded stage by stage and guarantees melting temperature, it is ensured that lower-molecular substance is waved
The safety of hair and processing.
The present invention selects material of main part of the 4045M rubber as sizing material, and Mooney low-flow is good, and ethylene contents are low, low temperature
Performance is good, and the high-sulfurized speed of Third monomer content is fast；Cooperation uses carbon black N550, and the performance and processing technology for meeting rubber are wanted
It asks；The addition of softening plasticizer T16 guarantees the dynamic property for not reducing rubber first, while improving the processability of rubber, excellent
Ageing-resistant performance and resistance to braking fluid performance；The use of peroxide vulcanizing agent ensure that the appearance of rubber product and good
Physical mechanical property.
The present invention has the characteristics of high-low temperature resistant aging under use environment, resistance to braking fluid, and long service life is suitable for
Braking sealing system.
