Problems solved by technology

In the past, the cleaning ability of the grinding fluid used for automobile clutches was poor, and the metal wear debris easily adhered to the surface of the grinding wheel, resulting in clogging of the pores of the grinding wheel, dulling, and short service life; at the same time, the lubricating performance and cooling performance were poor, resulting in burns, cracks, roughening and burns on the surface of the workpiece. Scratch, so that the surface roughness of the processed workpiece is large; there is also a prominent problem that the surface rusts quickly after the diaphragm grinding process, which has a great impact on the subsequent process
Although the existing diaphragm water-based grinding fluid has changed the shortcomings of the original grinding fluid and met the basic process performance requirements of diaphragm grinding, its cost is still relatively high and has nothing to do with the environmental protection requirements of energy saving and emission reduction. there is still distance

Embodiment 1

[0041] Raw materials and weight percentages are as follows: phytic acid 1.8-2.2%, sodium benzoate 5-7%, alcohol amine 7-9%, sodium carbonate 3.5-4.5%, sodium thiosulfate 0.8-1.2%, polyethylene glycol 11-13 %, 2.5-3.5% triethanolamine oleate, 1.8-2.2% sodium dodecylbenzene sulfonate, 1.8-2.2% defoamer, 0.4-0.6% isothiazolinone, and 58-61% deionized water.

[0042] Each raw material can be selected within the weight range, so that the weight sum is 100%.

[0043] The production method is as follows:

[0044] a. First add the calculated amount of deionized water, phytic acid, sodium benzoate, and triethanolamine into the reaction kettle in turn, start the stirrer, and stir for 1 hour at normal temperature with a rotating speed of 200 rpm;

[0045] b. Then add the calculated amount of sodium carbonate, sodium thiosulfate, polyethylene glycol, triethanolamine oleate, sodium dodecylbenzenesulfonate, defoamer, and isothiazolinone into the reaction kettle in sequence, and heat To 50...

Embodiment 2

[0049] The production method is the same as in Example 1, except that the raw materials and weight percentages are as follows: 2% phytic acid, 6% sodium benzoate, 8% triethanolamine, 4% sodium carbonate, 1% sodium thiosulfate, 12% polyethylene glycol, oleic acid Triethanolamine 3%, sodium dodecylbenzene sulfonate 2%, defoamer 2%, isothiazolinone 0.5%, deionized water 59.5%.

[0050] Product Appearance: Viscous, slightly purple, transparent liquid.

Abstract

The invention discloses a water-based grinding fluid specialized for automobile clutch diaphragm which can reduce grinding temperature and force to maximum extent, improve process efficiency of grinding, ensure grinding precision and surface quality, prolong life of grinding wheel, reduce cost, satisfy requirements of environmental protection and production method thereof. Raw materials of water-based grinding liquor and weight percentages are phytic acid 1.8-2.2%, sodium benzoate 5-7%, alkylol amine 7-9%, sodium carbonate 3.5-4.5%, hyposulfite of soda 0.8-1.2%, polyethyleneglycol 11-13%, oleate triethanolamine 2.5-3.5%, sodium dodecylbenzene sulfonate 1.8-2.2%, foam killer 1.8-2.2%, 2-methyl-3(2H)-isothiazolone 0.4-0.6%, de-ionized water 58-61%. The production method is synthesis with stirring under condition of normal temperature - medium temperature - normal temperature.

Description

Technical field: [0001] The invention relates to a grinding fluid for metal grinding, in particular to a grinding fluid which can reduce the grinding temperature and grinding force to the greatest extent, improve the grinding efficiency, ensure the grinding accuracy and surface quality of the workpiece and extend the length of the grinding wheel. A special water-based grinding fluid for automotive clutch diaphragms and a production method that have a long service life, reduce costs, and meet environmental protection requirements. Background technique: [0002] Grinding is a processing method that uses the high-speed rotation of the grinding wheel to cut the workpiece. During the grinding process, due to a large number of deformations and new friction surfaces, and the grinding wheel also bears huge impact and vibration during the processing, Therefore, there will be problems such as reduced durability of the grinding wheel, rough machined surface of the workpiece, and poor d...
