Abstract
The utility model relates to an EPDM (Ethylene-Propylene-Diene Monomer) high-pulse cooling water pipe. The EPDM high-pulse cooling water pipe comprises an inner rubber layer, a reinforcing layer and an outer rubber layer, and is characterized in that the reinforcing layer is tightly wrapped outside the inner rubber layer, and the outer rubber layer is wrapped outside the reinforcing layer; and the inner rubber layer and the outer rubber layer are made of EPDM. The EPDM high-pulse cooling water pipe not only has excellent fatigue resistance, high temperature resistance and ageing resistance, but also has high pulse; quality problems such as fracture, leakage and the like are not caused when the pulse is up to 300000 times in a pulse laboratory imitating an extremely severe environment; and in addition, the compression set also completely accords with the TL52361 standard, and the safety and the practical applicability of a cooling water pipe assembly are improved.
Description
Technical field
The utility model relates to the water-cooling tube assembly of automobile, particularly relates to a kind of ethylene propylene diene rubber high impulse water-cooling tube.
Background technique
The water-cooling tube assembly of automobile is divided into intake pipe assembly and outlet pipe assembly, intake pipe is by radiator outlet (water tank just) a section to the engine water pump water intake, outlet pipe is a section from the thermostat to the water inlet of radiator, the effect of radiator is exactly the circulating water (cooling liquid just) that flows in the cooled engine, and water-cooling tube just transmits the passage of the cooling water between motor and the radiator, is that motor is unlikely to overheated assurance.Along with the development of automobile industry, the air displacement of motor is increasing, and the Environmental Conditions of water-cooling tube is also more and more abominable, and simultaneously, people are but more and more higher to the requirement of water-cooling tube Security and durability degree, because they are bodyguards of protection motor.
The water-cooling tube assembly of automobile is divided into intake pipe assembly and outlet pipe assembly, intake pipe is by radiator outlet (water tank just) a section to the engine water pump water intake, outlet pipe is a section from the thermostat to the water inlet of radiator, the effect of radiator is exactly the circulating water (cooling liquid just) that flows in the cooled engine, and water-cooling tube just transmits the passage of the cooling water between motor and the radiator, is that motor is unlikely to overheated assurance.Along with the development of automobile industry, the air displacement of motor is increasing, and the Environmental Conditions of water-cooling tube is also more and more abominable, and simultaneously, people are but more and more higher to the requirement of water-cooling tube Security and durability degree, because they are bodyguards of protection motor.
In the prior art, reach common understanding as the material of main part of water-cooling tube,, therefore have good resistance to oxidation, anti-ozone and erosion-resistant ability because the main polymer chain of ethylene propylene diene rubber is fully saturated with ethylene propylene diene rubber.But, the dynamic performance of the ethylene-propylene-diene monomer sebific duct that tratitional technology is made is general, especially at high temperature be difficult to embody compellent data under the pulse fatigue test, promptly the fatigue resistance under the mal-condition of simulation is relatively poor, allowing the people can't help heart to whole automobile---some worries motor, and this obviously can not satisfy the requirement of present automobile industry development.Therefore, how to improve processing technology under the prerequisite that does not change the sebific duct structure, satisfying Hyundai Motor industry becomes a big problem to the requirement of water-cooling tube assembly.
But for water-cooling tube, be not that the data of anti-pulse test are high more good more, especially in the civilian vehicle industry, the position of each part is all very limited in the car, has deviation to interfere with each other slightly.As a rule, the elasticity of rubber pipe is more little, its fatigue resistance is just high more, but under pulse test constantly, rubber pipe will inevitably not only may destroy the structure of rubber pipe because of not having elasticity or elasticity too small and swell gradually, more may interfere with other parts on every side, influence the proper functioning 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 pipe, pay close attention to the elastic textual criticism of rubber pipe---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 pipe, this both requires rubber pipe to reduce elasticity as far as possible and adapts to impulse test with regard to being equivalent to, show rebound elasticity again as far as possible and meet the standard of compression set, apparently, under the situation of single glue kind, this is an impossible mission substantially.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of ethylene propylene diene rubber high impulse water-cooling tube is provided, this water-cooling tube not only has outstanding endurance, high temperature resistant, ageing-resistant performance, and pulse height, improve the working life of water-cooling tube assembly under exceedingly odious condition greatly, improved the Security and the practicability of water-cooling tube assembly.
The technological scheme that provides according to the utility model: ethylene propylene diene rubber high impulse water-cooling tube, comprise inner glue layer, reinforced layer and outer glue-line, it is characterized in that: described reinforced layer closely is wrapped in outside the inner glue layer, and outer glue-line is coated on outside the reinforced layer; Described inner glue layer and outer glue-line are made by ethylene propylene diene rubber.
As further improvement of the utility model, described reinforced layer be adopt aramid line with braiding, the knitting or wrapped of twining on interior sebific duct and form.
As further improvement of the utility model, the pipe thickness of described water-cooling tube is 3 ~ 8mm.
The utility model compared with prior art, advantage is: the utility model not only has outstanding endurance, high temperature resistant, ageing-resistant performance, and pulse height, reach pulse and break more than 300000 times in that the pulse test of simulating rugged 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 working life of water-cooling tube assembly under exceedingly odious condition greatly, improved the Security and the practicability of water-cooling tube assembly.
