Abstract
The invention discloses a rapid detection method for dispersion of titanium dioxide in oil paint. The rapid detection method comprises the following steps: adding oil dispersing agents and titanium dioxide into vegetable oil in sequence, and uniformly stirring to obtain mixed slurry; and detecting the dispersion of the mixed slurry through a scraper fineness meter. According to the rapid detection method, a formula for preparing the mixed slurry is simple and the cost is relatively low; the added oil dispersing agents BYK-110 and BYK-161 have good dispersion effect on titanium dioxide, so that the dispersion time can be effectively shortened. According to the rapid detection method for detecting the dispersion of titanium dioxide in oil paint disclosed by the invention, the detected results can be obtained within 20 minutes.
Description
Technical field
The present invention relates to the dispersed method for quick of a kind of titanium dioxide in oil paint, belong to material property detection technique field.
Background technology
Titanium dioxide is a kind of colory white powder pigment, there is good light scattering ability, because whiteness is good, colouring power is high, strong covering power, have simultaneously higher chemical stability and good weatherability, nonpoisonous and tasteless, human body is had no stimulation, be widely used in the industries such as coating, plastics, papermaking, ink.
In high-end oil paint is produced, higher dispersiveness is required to the titanium dioxide as primary raw material.The dispersiveness of current detection titanium dioxide in oil paint is generally first by fixing recipe configuration coating, gets a certain amount of titanium dioxide and joins in coating, then carry out grinding distribution with muller, then detects the dispersiveness of titanium dioxide in coating with Hegman grind gage.But the formula that most of oil paint dispersiveness detects is comparatively complicated, and cost is higher.And the process need long period of grinding distribution, cause whole sense cycle very long, be unfavorable for that the quality of production controls.In addition, current testing result reading is all adopt artificial reading, and error is larger.Therefore, need to develop a kind of simple and reliable titanium dioxide method for quick dispersed in oil paint.
Summary of the invention
The technical problem to be solved in the present invention is to provide the dispersed method for quick of a kind of titanium dioxide in oil paint, the method can detect the dispersiveness of titanium dioxide in oil paint fast and accurately, greatly reduces testing cost and shortens detection time.
Concrete scheme is, the dispersed method for quick of a kind of titanium dioxide in oil paint, comprises the following steps:
1) spreading agent, titanium dioxide are joined in vegetable oil successively, after stirring, obtain mixed slurry;
2) dispersiveness of mixed slurry is detected with Hegman grind gage.
3) Analysis of test results, more hour, illustrate that accuracy of detection is higher, when parallel sample testing result extreme difference≤3 μm, accuracy of detection meets the demands for the extreme difference of parallel sample testing result; When the mean value of the dispersed testing result of sample is lower, the dispersiveness of interpret sample is better, and when mean value≤20 μm of parallel sample testing result, the dispersiveness of this titanium dioxide meets the dispersed requirement of high-end oil paint.
Further, spreading agent used in step 1) is oiliness dispersant B YK-110, any one in BYK-161.
Further, vegetable oil used in step 1) is linseed oil, castor oil, any one in soybean oil.
Further, in step 1), the mass ratio of titanium dioxide and spreading agent is: 1:0.005 ~ 0.015, and the mass ratio of titanium dioxide and vegetable oil is: 1:3 ~ 10.
Further, carry out stirring with homo-mixer in step 1) and prepare slip.
Further, step 2) in reading be adopt Labman instrument readings.
Advantage of the present invention: the formula that this method prepares mixed slurry is simple, and cost is lower, simple to operate; The oiliness dispersant B YK-110 used in this method, BYK-161 is good to the dispersion effect of titanium dioxide, and use homo-mixer to disperse, significantly can shorten jitter time, namely testing result can be completed in 20min, in addition, adopt Labman instrument readings can greatly reduce the error of artificial reading, improve accuracy.
