Abstract

The invention discloses a kind of dispersed quick determination method of titanium dioxide in oil paint, oiliness dispersant and titanium dioxide are added sequentially in vegetable oil, mixed slurry is obtained after stirring, the dispersiveness of mixed slurry is detected with Hegman grind gage.The formula that this method prepares mixed slurry is simple, and cost is relatively low, wherein the oiliness dispersant B YK 110, the BYK 161 that add have good dispersion effect to titanium dioxide, can effectively shorten jitter time.Testing result can be completed by being detected by this method in dispersiveness of the titanium dioxide in oil paint, 20min.

Description

A kind of dispersed quick determination method of titanium dioxide in oil paint
Technical field
The present invention relates to a kind of dispersed quick determination method of titanium dioxide in oil paint, category material property detection skill Art field.
Background technology
Titanium dioxide is a kind of white powder pigment best in quality, with good light scattering ability, because whiteness is good, Se Ligao, strong covering power, at the same there is higher chemical stability and preferable weatherability, it is nonpoisonous and tasteless, non-stimulated to human body Effect, is widely used in the industries such as coating, plastics, papermaking, ink.
In the production of high-end oil paint, there is higher dispersiveness to the titanium dioxide requirement as primary raw material.Inspection at present Dispersiveness of the titanium dioxide in oil paint is surveyed usually first by fixed recipe configuration coating, takes a certain amount of titanium dioxide to add Into coating, then it is ground with grinder scattered, then detects dispersiveness of the titanium dioxide in coating with Hegman grind gage.But It is that the formula that most of oil paint dispersiveness is detected is complex, cost is higher.And the process needs of grinding distribution are longer Time, cause whole detection cycle very long, be unfavorable for quality of production control.In addition, current testing result reading is all to use Artificial reading, error is larger.Accordingly, it would be desirable to develop a kind of quick inspection dispersed in oil paint of simple and reliable titanium dioxide Survey method.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of dispersed quick detection side of titanium dioxide in oil paint Method, this method can fast and accurately detect dispersiveness of the titanium dioxide in oil paint, greatly reduce testing cost and Shorten detection time.
Concrete scheme is that a kind of dispersed quick determination method of titanium dioxide in oil paint comprises the following steps:
1)Dispersant, titanium dioxide are added sequentially in vegetable oil, after stirring, mixed slurry is obtained;
2)The dispersiveness of mixed slurry is detected with Hegman grind gage.
3)Analysis of test results, the extreme difference of parallel sample testing result gets over hour, illustrates that accuracy of detection is higher, works as Duplicate Samples During product testing result extreme difference≤3 μm, accuracy of detection, which is met, to be required;When the average value of the dispersed testing result of sample is lower, say The dispersiveness of bright sample is better, and when average value≤20 μm of parallel sample testing result, the dispersiveness of the titanium dioxide meets height Oil paint dispersiveness is held to require.
Further, step 1)In used dispersant be any one in oiliness dispersant B YK-110, BYK-161.
Further, step 1)In used vegetable oil be linseed oil, castor oil, any one in soybean oil.
Further, step 1)The mass ratio of middle titanium dioxide and dispersant is:1:0.005 ~ 0.015, titanium dioxide and vegetable oil Mass ratio be:1:3~10.
Further, step 1)Middle be stirred with homogenizer prepares slurry.
Further, step 2)In reading be use Labman instrument readings.
Advantages of the present invention:The formula that this method prepares mixed slurry is simple, and cost is relatively low, simple to operate;In this method Oiliness the dispersant B YK-110, BYK-161 used is good to the dispersion effect of titanium dioxide, and is disperseed using homogenizer, Can significantly shorten in jitter time, 20min can complete testing result, in addition, can be big using Labman instrument readings The error of artificial reading is reduced greatly, improves accuracy.
