Abstract
The invention relates to a damping fluid of a hydraulic suspension product of an automobile engine. The damping fluid consists of the following raw materials in parts by mass: 50-70 parts of glycol, 25-45 parts of propylene glycol and 8-12 parts of triethanolamine. The damping fluid is prepared by mixing a plurality of components and has simple preparation procedure and process. The hydraulic suspension product of the automobile engine, produced by the damping fluid, has favorable heat resistance and anti-freezing properties, freezing point of not less than 59 DEG C and boiling point of not less than 192 DEG C and favorable corrosion-resistance, antirust and viscosity-temperature characteristics, overcomes the defect that the traditional damping fluid has no function of oxidation prevent, has no corrosion to metals and no influence on rubber and is suitable for the damping fluid of the automobile hydraulic suspension product with natural rubber as a main reed body and metal framework assembly.
Description
Technical field
The present invention relates to the damp liquid technical field, exactly is a kind of damp liquid of motor car engine hydraulic mount product.
Background technique
The main spring body of damp liquid in motor car engine hydraulic mount product contact (material: natural gum), connect runner (material: plastics, aluminium or steel plate), leather cup (material: natural gum or ethylene propylene rubber) all is not acidproof, not corrosion resistant; It is improper that damp liquid uses, and can damage product or reduce product working life.The conventional used material of damp liquid is ethylene glycol and distilled water.The advantage of ethylene glycol in damp liquid be antifreeze, resistance to heat good; But contain hydroxyl in the ethylene glycol; Through normal temperature work down, time length is oxidized to acid easily and can causes rubber, iron and steel, aluminum component corrosion and incrustation scale existence, and distilled water also can cause metal erosion, get rusty after peroxidating simultaneously; To develop damp liquid for this reason and must consider make damp liquid can not cause metal to get rusty the product component article, the corrosion and can be not influential to rubber.
Summary of the invention
The object of the present invention is to provide a kind of not only anticorrosive, oxidation resistance is outstanding, and the damp liquid of the motor car engine hydraulic mount product that is easy to prepare.
The present invention adopts following technological scheme:
The invention is characterized in by the raw material of following mass parts and form: ethylene glycol 50-70, propylene glycol 25-45, triethanolamine 8-12.
A kind of damp liquid of motor car engine hydraulic mount product is characterized in that its raw material by following mass parts forms: ethylene glycol 60, propylene glycol 40, triethanolamine 10.
A kind of damp liquid of motor car engine hydraulic mount product is characterized in that: it also contains aluminium-magnesium silicate 1-2 mass parts.
Preparation method of the present invention is: raw materials such as ethylene glycol, propylene glycol, triethanolamine are stirred and can use by mass parts.If the present invention does not use at once, advise canned arriving in the sealable container, in order to avoid the damp liquid long term exposure absorbs harmful matter in large quantity of moisture and the air, thereby reduce corrosion-resistant, the oxidation resistant function that should possess.
Beneficial effect of the present invention is:
1, the present invention is mixed by multiple composition, propylene glycol except antifreeze, resistance to heat good, it is good also to possess sticking warm nature, has moisture absorbing to reduce the advantage of damp liquid moisture content; Triethanolamine except antifreeze, resistance to heat good, also possesses acid gas absorption, antirust, corrosion-resisting function, protective money metal surface, the function of anti-oxidation.Above-mentioned two kinds of materials are applied to the performance such as anticorrosive and anti-oxidant that can increase damp liquid in the damp liquid.
2, its manufacturing process, technology are simple; The motor car engine hydraulic mount product that this damp liquid is produced has good heat-resisting, resistance to frost; Its freezing point >=59 ℃, boiling point >=192 ℃, to suppress burn into antirust, and sticking warm nature is all than more excellent; Solved the shortcoming of anti-oxidation of damp liquid that traditional ethylene glycol and distilled water mixes; Can not cause corrosion to metal simultaneously, can be not influential to rubber, it is applicable to that with natural gum be the suspend damp liquid of product of the automobile hydraulic of main spring body, metal frame assembly.
3, add aluminium-magnesium silicate simultaneously as water-thickening agent, can make the present invention have high viscosity, therefore excellent resistance stability, resiliency can be provided, make level and smooth, smooth and easy, the motion accurately of parts ability, be applicable to the needs of different vehicle.
