Abstract
The invention relates to an ethyl-ene propylene diene methylene rubber formula used for high pulse automobile cooling water pipe assembly, which is characterized by comprising the following components of raw materials according to parts by weight: 10-50 parts of ethyl-ene propylene diene methylene rubber 4045; 50-90 parts of ethyl-ene propylene diene methylene rubber 5601; 2-8 parts of zinc oxide; 1-7 parts of stearic acid; 1-5 parts of anti-aging agent RD; 40-90 parts of fast extruding carbon black N550; 10-40 parts of paraffinic based oil; 1-8 parts of cross-linking agent DCP; and 1-8 parts of cross-linking agent TAIC. The cooling water pipe assembly made by the formula not only has excellent resistance to fatigue, high temperature and ageing, but also high pulse. The cooling water pipe assembly does not crack or leak when reaching over 300 thousand times of pulse in a pulse lab simulating an extremely severe environment, nor has other quality problems, conforming to the requirement of TL52361 standard (over 8 thousand times).
Description
Technical field
The present invention relates to the elastomeric material technical field, particularly relate to a kind of formula of ethylene propylene terpolymer with that is used for the cooling water car pipe assembly of high impulse.
Background technology
The water-cooled tube assembly of automobile is divided into water inlet pipe assembly and rising pipe assembly, water inlet pipe is by radiator outlet (water tank just) a section to the engine water pump water-in, rising pipe is a section from the thermostat to the water inlet of radiator, the effect of scatterer is exactly a mobile recirculated water (cooling fluid just) in the cooled engine, and water-cooled tube just transmits the passage of the water coolant between engine and the scatterer, is that engine is unlikely to the superheated assurance.Along with the development of automobile industry, the free air delivery of engine is increasing, and the environment for use of water-cooled tube is also more and more abominable, and simultaneously, people are but more and more higher to the requirement of water-cooled tube security and durability degree, because they are bodyguards of protection engine.
In the prior art, reach common understanding as the material of main part of water-cooled tube,, therefore have good resistance to oxidation, anti-ozone and erosion-resistant ability because the main polymer chain of terpolymer EP rubber is fully saturated with terpolymer EP rubber.But, the dynamic property of the ethylene-propylene-diene monomer sebific duct that traditional technology is made is general, especially at high temperature be difficult to embody compellent data under the pulse fatigue test, promptly the resistance to fatigue under the mimic mal-condition is relatively poor, and this obviously can not satisfy the requirement of present automobile industry development.Therefore, how to develop the water-cooled tube assembly of high impulse, satisfying Hyundai Motor industry becomes a big problem to the requirement of water-cooled tube assembly.
As a rule, the elasticity of rubber hose is more little, its resistance to fatigue is just high more, but under pulse test constantly, rubber hose will inevitably not only may destroy the structure of rubber hose because of not having elasticity or elasticity too small and swell gradually, more may interfere with other parts on every side, influence the works better of other parts in the car, bring very big potential safety hazard.So a lot of standards in Europe are not just paid attention to the anti-pulse number of rubber hose, pay close attention to the elastic textual criticism of rubber hose---compression set simultaneously yet.The TL52361 standard that picture is famous in the industry, just the quite standard of harsh compression set has been proposed rubber hose, this both requires rubber hose to reduce elasticity as far as possible and adapts to pulse testing with regard to being equivalent to, show rebound resilience again as far as possible and meet the standard of compression set, apparently, for the ethylene-propylene-diene monomer sebific duct that traditional technology is made, this is an impossible mission substantially.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of formula of ethylene propylene terpolymer with is provided, the water-cooled tube assembly that adopts this prescription to make not only has outstanding antifatigue, high temperature resistant, ageing-resistant performance, and pulse height, improve the work-ing life of water-cooled tube assembly under exceedingly odious condition greatly, improved the security and the practicality of water-cooled tube assembly.
According to technical scheme provided by the invention: the described formula of ethylene propylene terpolymer with that is used for high impulse water-cooled tube assembly is characterized in that: meter by weight comprises following feed composition: 4045,10～50 parts of terpolymer EP rubbers; 5601,50～90 parts of terpolymer EP rubbers; Zinc oxide, 2～8 parts; Stearic acid, 1～7 part; Anti-aging agent RD, 1～5 part; Fast carbon black N550,40～90 parts of extruding; Paraffinic based oil, 10～40 parts, crosslink agent DCP, 1～8 part; Linking agent TAIC, 1～8 part.
The present invention compared with prior art, advantage is: the water-cooled tube assembly that adopts this prescription to make not only has outstanding antifatigue, high temperature resistant, ageing-resistant performance, and pulse height, the water-cooled tube assembly reaches pulse and breaks more than 300000 times in that the pulse test of simulating severe environment extremely is indoor, the situation of quality problems such as seepage, meet TL52361 standard-required (more than 180000 times), and compression set also meets the standard of TL52361 fully, improve the work-ing life of water-cooled tube assembly under exceedingly odious condition greatly, improved the security and the practicality of water-cooled tube assembly.
Embodiment
The invention will be further described below in conjunction with specific embodiment.
Embodiment 1～embodiment 10 all takes by weighing raw material according to the parts by weight proportioning shown in the table 1, adopts mill to plasticate then, makes rubber product.
Table 1:
The rubber product that embodiment 1～embodiment 10 makes detects test according to " GB/T53 1.1-2008 ", " GB/T528-2009 ", " GB/T529-2008 " examination criteria, and the result is as shown in table 2:
Table 2:
Then the rubber product that obtains among the foregoing description 1～embodiment 10 is processed into the water-cooled tube assembly, detects test according to the TL52361 examination criteria, detected result is as shown in table 3:
Table 3:
Interpretation of result: the experimental data from table 2 and table 3 as can be seen, formula technique index of the present invention meets technological standard fully, the needs of product desired properties have been reached, simultaneously fabulous solution the relatively poor problem of the resistance to fatigue of water-cooled tube assembly under the mimic mal-condition made of terpolymer EP rubber, the water-cooled tube assembly is ability pulse testing more than 300000 times not only, and compression set also meets the standard of TL52361 fully, we can say at home and abroad to maintain the leading position fully in the water-cooled tube field.
The prescription that the present invention proposes with two kinds of terpolymer EP rubbers and usefulness, below describe in detail, person skilled is under the situation that does not break away from content of the present invention, spirit and scope, prescription described in the present invention is changed or suitably change and combination, still should be considered as being included in spirit of the present invention, scope and the content.
