Abstract
The invention relates to corrosion-resistant anti-freezing damping fluid for a hydraulic suspension product of an automotive engine, which comprises the following raw materials by weight portions: 50-70 portions of ethylene glycol, 25-45 portions of propylene glycol, 8-12 portions of triethanolamine, 3-5 portions of benzotriazole, 6-10 portions of sodium benzoate, and 3-5 portions of disodium hydrogen phosphate. The manufacturing procedures and process are simple, the hydraulic suspension product of the automotive engine produced with the damping fluid has good thermal resistance, good anti-freezing performance, good scale resistance, good corrosion inhibiting performance, good rust resistance and good viscosity-temperature characteristics, the defect that oxidation cannot be prevented by the traditional corrosion-resistant anti-freezing damping fluid formed via mixing of ethylene glycol and distilled water can be overcome, no corrosion can be caused to metals, and rubber cannot be affected.
Description
Technical field
The present invention relates to the damp liquid technical field, exactly is a kind of antifreeze damp liquid of corrosion resistant 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 antifreeze damp liquid of corrosion resistant 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 that its raw material by following mass parts forms: ethylene glycol 50-70, propylene glycol 25-45, triethanolamine 8-12, benzotriazole 3-5, Sodium Benzoate 6-10, sodium hydrogen phosphate 3-5.
The antifreeze damp liquid of corrosion resistant of described a kind of motor car engine hydraulic mount product is characterized in that its raw material by following mass parts forms: ethylene glycol 60, propylene glycol 20, triethanolamine 10, benzotriazole 3, Sodium Benzoate 8, sodium hydrogen phosphate 4.
The antifreeze damp liquid of corrosion resistant of described a kind 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, benzotriazole, Sodium Benzoate, sodium hydrogen phosphate 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 antirust 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.Benzotriazole has good antiseptic and rustproof effect, adds Sodium Benzoate and sodium hydrogen phosphate simultaneously, and the long-effective corrosion performance can be provided, and cheap, pollution-free.
2, manufacturing process of the present invention, technology are simple; The motor car engine hydraulic mount product that this damp liquid is produced has good heat-resisting, resistance to frost; It is antirust to suppress burn into; Sticking warm nature is all than more excellent, solved the shortcoming of anti-oxidation of the antifreeze damp liquid of corrosion resistant 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 antifreeze damp liquid of corrosion resistant of product of the automobile hydraulic of main spring body, metal frame assembly.
3, add aluminium-magnesium silicate 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.
