Embodiment 1

[0047]Use the same amount of organic silicon emulsion A, surface-treat the same batch of inorganic coating material of rutile titanium dioxide, do two groups of parallel tests 1# and 2#, measure the percentage of C and Si in the titanium dioxide before the treatment according to the present invention The contents are 0.095 and 0.249 respectively, and the percentages of C and Si in No. 1 gas powder are 0.160 and 0.280 respectively. -1 ~3000cm -1 There are obvious absorption peaks between them; the percentage contents of C and Si in No. 2 gas powder are 0.158 and 0.250 respectively, and the difference spectrum of its infrared spectrum shows that C-H is at 2850cm -1 ~3000cm -1 obvious absorption peaks.

[0048] As can be seen from the data of this example, the difference spectrum of the infrared spectrum is the same, and the change of C is the same, so it is considered that C is stable when the surface of titanium dioxide is treated organically; Si is unstable, so it is judged...

Embodiment 2

[0050] Use the same amount of organic silicon emulsion B to treat the same batch of inorganic coating materials of rutile titanium dioxide on the surface, do two groups of parallel tests 1# and 2#, and measure the percentage of C and Si in the titanium dioxide before the treatment according to the present invention Containing 0.095 and 0.240 respectively, the percentages of C and Si in the No. 1 gas powder material are 0.148 and 0.281 respectively, and the difference spectrum of its infrared spectrum shows that C-H is at 2850cm -1 ~3000cm -1 There are obvious absorption peaks between them; the C and Si percentages of C-H2# gas powder are 0.150 and 0.288, respectively, and the difference spectrum of its infrared spectrum shows that C-H is at 2850cm -1 ~3000cm -1 There are obvious absorption peaks between them.

[0051] From the data of this example, it can be seen that the difference spectrum of the infrared spectrum is the same, the change of C is the same, and the change of...

Abstract

The invention belongs to the technical field of chemical engineering, and particularly relates to a method for detecting the organic treatment stability of the surface of titanium dioxide. The method comprises the following steps that a, a titanium dioxide triple-washing material and gas powder are dried to reach the constant weight; b, an infrared spectrometer is used for detection; c, differential spectra of infrared spectra of the gas powder of each batch and the triple-washing material are compared; d, an organic treatment agent is dried to reach the constant weight, and an energy disperse spectroscopy is used for qualitatively detecting all elements; e, an element analyzer is used for qualitatively detecting all the elements of the triple-washing material and the gas powder material of each batch; f, if the differences between the gas powder materials of the batches and the content of a certain element of the triple-washing material are different, the added amount of the organic treatment agent is not stable; if the differences are the same, the added amount of the elements is stable. The method has the guiding significance of feedback regulation of improving the organic treatment agent addition technology.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a method for detecting the stability of organic treatment on the surface of titanium dioxide. Background technique [0002] Titanium dioxide is an important inorganic functional material, because of its unique physical and chemical properties, it is widely used in coatings, plastics, paper, ink, chemical fiber, rubber, cosmetics and other industries. Organic treatment improves the compatibility of titanium dioxide with resins and organic solvents, thereby improving the application performance of titanium dioxide. [0003] According to current relevant literature reports, organic treatment agents are added in two processes of drying and jet milling in industrial production, and are adsorbed on the surface of titanium dioxide physically or chemically. The adsorption method and the uniform stability of the organic treatment agent affect the dispersibility of t...
