Abstract
The invention relates to a method for detecting the UV (ultraviolet) light stability of special titanium dioxide for paper making. The method comprises the following steps that the titanium dioxide and carbonate are uniformly dispersed into linseed oil, castor oil, glycerol or petrolatum oil to obtain mixed size which is prepared into a wet film, and the wet film is clamped in the middle through transparent glass sheets to form a film sheet; the CIEL*a*b* of the film sheet is detected through a spectral color photometer; the UV light used by the film sheet is uniformly illuminated, and the film sheet is put into the spectral color photometer to detect the CIEL*a*b*; according to the detected CIEL*a*b* before and after illumination, the triangle E is calculated by the spectral color photometer, namely the capacity of the titanium dioxide to resist the UV light; parallel samples are detected; and when the difference of the parallel detection results is less than 0.15 and the average value of the parallel sample detection results is less than 0.5, the UV light stability of the titanium dioxide conforms to the requirement of the special titanium dioxide for paper making. The method manufactures the samples into a wet film mode, the UV light stability of the titanium dioxide can be rapidly and directly monitored, the precision of the detection results is good, and the detection cost is low.

Technical solution of the present invention is:
A kind of detection method of papermaking special titanium pigment UV light stability, its concrete steps are as follows:
1, titanium dioxide and carbonate are dispersed among the component A, obtain mixed slurry, described component A is a kind of in linseed oil, castor oil, glycerine, the vaseline oil, described carbonate is calcium carbonate, manganese carbonate or ceruse, wherein, the mass ratio of titanium dioxide and carbonate, component A is respectively 1:1～1:2,1:3～1:5;
2, mixed slurry is prepared into wet film, the two sheet glass sheets identical with transmittance are clipped in the middle wet film, make diaphragm;
3, detect the CIEL*a*b* of diaphragm with spectrophotometric color measurement instrument;
4, be 800 μ w/cm with sample diaphragm intensity
2～1000 μ w/cm
2Ultraviolet light uniform irradiation 2h～6h, put into spectrophotometric color measurement instrument and detect CIEL*a*b*;
5, according to the CIEL*a*b* that tests behind the pre-irradiation, by the automatic Ji Suan of spectrophotometric color measurement instrument Chu ⊿ E, be the titanium dioxide luminous energy of anti-UV power;
6, carry out parallel sample according to step 1～step 5 and detect, when the Parallel testing result poor＜0.15, the mean value of parallel sample testing result＜0.5 the time, this titanium dioxide UV light stability meets the requirement of papermaking special titanium pigment.
Dispersion described in the step 1 is to adopt lapping mode.
Preparation is during diaphragm in the step 2, mixed slurry is pressed into wet film or with the striking of wet film preparing device with two sheet glass sheets.
Beneficial effect of the present invention:
The method becomes the wet film form with sample preparation, detect again after need not to make paper, can fast, directly monitor titanium dioxide UV light stability, in test process, be radiated at uniformly on the titania wet film with ultraviolet light, detecting the titanium dioxide luminous energy of anti-UV power by spectrophotometric color measurement instrument, testing result precision is good, and testing cost is low; Simple and easy to do detection method is provided for the anti-UV light stability of papermaking producer and titanium dioxide producer assessment titanium dioxide, the quality that improves the papermaking special titanium pigment for titanium dioxide producer provides technical guarantee.
