(2) Ambient air particulate matter PM2.5 (beta-ray method) test: according to the technical requirements and the detection method of the continuous automatic monitoring system of the HJ 653-2013 environmental air particulate matters, a DASIBI 4000 series 7201 PM2.5 analyzer and a Defender flow calibrator are utilized, the environmental temperature is 30 ℃, the relative humidity is 55%, the test time interval is 1h, and the test time lasts for 24h; the detection results are shown in table 1, the value of the detection result PM2.5 in table 1 is an average value of 24h, and the lower the value is, the smaller the smoke amount is;
(3) Defoaming property: the defoaming performance of the cutting fluid is detected according to GB/T6144, and the detection result is shown in Table 1;
(4) Defoaming stability: in order to detect the defoaming stability of the cutting fluid, the defoaming agent in the cutting fluid is detected to not only quickly destroy foam, but also prevent foam generation in a period of time, and the defoaming capability of the defoaming agent is classified into four grades: the A level-defoaming time is less than 15s; b grade-defoaming time is less than 30s; grade C-defoaming time is less than 60s; grade D-defoaming time is greater than 60s; the detection results are shown in Table 2;
table 1: examples 4, 7, 9 and comparative example 2 Performance test data
As can be seen from table 1, the base oil in the cutting oil of examples 5, 7 and 9 prepared by the application is used as a main body, and the extreme pressure agent, the corrosion inhibitor and the defoamer are added to synergistically act, so that the smoothness of the copper-aluminum composite material can be improved in the CNC processing process, meanwhile, the oleic glyceride and the extreme pressure agent are compounded to synergistically act, the lubricating property is excellent, the heat of a cutter can be rapidly taken away, the foam generated by volatilization of PAO base oil is inhibited, the health of workers is protected, and the environment is protected. The defoamer prepared by the application has excellent foam inhibition and defoaming effects.
