Abstract

The invention discloses a special environment-friendly complete-synthesis cutting fluid for drilling stainless steel and a preparation method thereof. The preparation method comprises the following steps: mixing and stirring 10 to 15 percent of extreme-pressure lubricant, 3 to 5 percent of hydroxylation sulfonation castor oil borate and water for 10 minutes to 1 hour at the temperature of 30 to 80 DEG C to obtain a mixed component A; mixing and stirring 5 to 15 percent of pH stabilizer, 5 to 8 percent of antirust agent and water for 10 minutes to 1 hour at the temperature of 30 to 80 DEG C to obtain a mixed component B; uniformly mixing and stirring 15 to 25 percent of surface active agent and 3 to 5 percent of coupling agent at the normal temperature and normal pressure to obtain a mixture component C; adding the mixed component A, the mixed component B and the mixed component C into a reaction kettle and stirring and mixing for 10 minutes to 1 hour at the temperature of 30 to 80 DEG C to obtain the product. The prepared product is good in lubricating property, washing property, antirust property and cooling property, long in service life and environment-friendly.

Description

technical field [0001] The present invention relates to a fully synthetic cutting fluid, more specifically, to a fully synthetic cutting fluid for stainless steel drilling. The invention also relates to a preparation method of a fully synthetic cutting fluid for stainless steel drilling, which belongs to the environment-friendly metal processing field of lubricating materials. Background technique [0002] Stainless steel has high tensile strength, yield strength, elongation and impact value in terms of mechanical properties, and its high temperature strength and hardness are also high. In addition, stainless steel also has high corrosion resistance and high temperature resistance. Therefore, it is widely used in industrial sectors such as machinery, petrochemical industry, electronic instrumentation, and national defense. [0003] Drilling is one of the most important forms of cutting, accounting for more than 50% of the total cutting (Zhang Houjiang, Fan Rui, Chen Wuyi, e...
