Description
Technical field:
The present invention relates to a kind of hydraulic suspension part of anhydrous engine multifunctional filling liquid mixture, be applied to the production of automobile industry.
Background technique:
Car design is towards large discharge capacity and high pulling torque, lightweight and the future development of travelling comfort more.Large discharge capacity and high pulling torque have worsened the vibration characteristics of car to a great extent, have a strong impact on the riding comfort of vehicle.Particularly domestic car mostly adopts the relatively poor four cylinder engine of balance, and the engine vibration isolation problem is particularly outstanding.Thereby the designing requirement of the critical component that the vibration noise of isolation motor is transmitted in the car-engine mounting supporting is more and more higher.
Desirable engine mounting product and structure guarantee that objectively Engine Mounting System has frequently change and amplitude variation characteristic, reduce internal car noise, improve control stability.Can decay because of the characteristic of road surface and the inhomogeneous high rigidity of low frequency Large Amplitude Vibration, low frequency that causes of engine combustion, large damped vibration; Should have the little rigidity of high frequency, little damping characteristic.
For satisfying the requirement of passenger car various aspects of performance, hydraulic mount arises at the historic moment and obtains a wide range of applications.Now become one of main vibration isolation technique of automobile power assembly.
Hydraulic mount is by rubber assembly and can form through throttle orifice or the inertia channel filling liquid two large divisions who produces damping of flowing.This filling liquid requires operating temperature range wide, in order to adapt to the operating ambient temperature of vehicle; Modest viscosity is in order to produce suitable damping when flowing; The working environment storehouse of filling liquid is the macromolecular materials such as rubber, plastics, also comprises metallic material, and therefore, filling liquid and rubber, moulding material and metallic material all should have good compatibility.
Retrieval finds that at present, what domestic engine hydraulic mount spare filling liquid was generally used is the cooling liquid of motor.This medium is because contain 35 parts～55 parts water and 45 parts～65 parts ethylene glycol, and cryogenic property can meet the demands, and still, produces easily vapour lock when ambient temperature is higher, and damping characteristic is changed, and loses stable fine and smooth and balanced effectiveness in vibration suppression.
Summary of the invention:
The object of the present invention is to provide a kind of hydraulic suspension part of anhydrous engine multifunctional filling liquid mixture, it possesses the characteristic of lower freezing point, solidifying point is low, boiling point and burning-point are high, are that rubber counterdie, rubber decoupling zero film and the rubber decoupling zero film edge of material has preferably compatibility, the indirect corrosivity after non-corrosiveness and the oxidation with Natural rubber, suitable viscosity, also meet the technical requirements of standard aspect with Compatibility in Plastics, its cost is low, and is pollution-free.The Character Comparison that may be used for several alcohols of the present invention is as shown in table 1.
The Character Comparison of several alcohols of table 1
| The class title | Water-soluble | The alcohol intersolubility | Condensation point/℃ | Boiling point/℃ | Flash-point/℃ | The NR compatibility | To metal protection | Can form hydrogen bond in theory |
| Ethylene glycol | Good | Good | -12 | 198 | 115 | Good | Nothing | Can |
| Diethylene glycol | Good | Good | -11 | 245 | 143 | Good | Nothing | Can |
| Triethylene glycol | Good | Good | -8 | 289 | 166 | Good | Nothing | Can |
In the screening to diethylene glycol, ethylene glycol and three kinds of alcohol of triethylene glycol, get two kinds of alcohol at every turn and make up, or three kinds of alcohol carry out the mixture that mixing preparation becomes the present invention to describe, just significantly differentiation of generation aspect the solidifying point index.
In the mixture of combination, no matter be the combination of triethylene glycol and diethylene glycol, the combination of triethylene glycol and ethylene glycol, or the combination of triethylene glycol, diethylene glycol and ethylene glycol, its solidifying point is all-9 ℃～19 ℃ variations; And in the combination of diethylene glycol and ethylene glycol, solidifying point is minimum can to reach-46 ℃ along with the ratio of the two is adjusted.Therefore, with the first-selection that is combined as of diethylene glycol and ethylene glycol.
After in a single day this mixture is filled in damper unit, just formed an airtight system.Diethylene glycol and ethylene glycol all are the carbohydrate of Institute of Micro-biology hobby in the component, and the breeding of anaerobic microorganism is inevitable, therefore, exist diethylene glycol and ethylene glycol by microbial consumption fall and rotten hidden danger.Be the generation that lessens the hidden dangers, just optionally added the Kathon CG anticorrosion and bactericidal agent of micro-industry, this germicide is widely used in the cosmetics, also can be fully compatible with the mixture of diethylene glycol and ethylene glycol.
Above-mentioned pure and mild alcohol ether is colourless liquid, still is colourless after the mixing.For ease of the on-the-spot filling of auto-producing, be easy to be unlikely to occur the problem of mistake filling with other liquid difference, optionally add the fluorescent dye of industry, fluorescent red, Day-Glo blue or fluorescent green all can.Its cost is low, and is pollution-free.
Technological scheme of the present invention is achieved in that a kind of hydraulic suspension part of anhydrous engine multifunctional filling liquid mixture, by the A component, and the B component, C component and D are grouped into; It is characterized in that: component A is ethylene glycol, and B component is diethylene glycol, the Kathon CG anticorrosion and bactericidal agent of component C industry, and the D component is the fluorescent dye of industry; Wherein component A accounts for 50 parts～80 parts of mixture gross mass, and B component accounts for 19.985 parts～49.994 parts of mixture gross mass, and component C accounts for 0.005 part～0.01 part of mixture gross mass, and component D accounts for 0.001 part～0.005 part of mixture gross mass.
The preparation method of described mixture is as follows: be ethylene glycol with component A, B component is that diethylene glycol mixes in above-mentioned ratio, after stirring 5～10min under 20～40 ℃ of temperature; After adding again the fluorescent dye of the Kathon CG anticorrosion and bactericidal agent of component C industry and component D industry, continue to stir 5～10min.
Good effect of the present invention is the raw material of selecting industry, utilizes component self and physicochemical characteristics each other, behind the formation mixture, particularly aspect viscosity temperature characteristic, possesses the synergistic effect of remarkable improvement.
