Abstract
The present invention relates to a kind of paper grade (stock) compositions of fluorescent whitening agents and preparation method thereof, paper grade (stock) compositions of fluorescent whitening agents is made up of according to weight part following composition: white dyes JD-3 is 0.5 ~ 1.0 part, Wet Strength Resin is 0.6 ~ 1.0 part, EX-SF DISPERSE BLUE EX-SF 300 RD is 0.02 ~ 0.1 part, sodium sulfate is 0.003 ~ 0.02 part, water is 90 ~ 100 parts.Preparation method's step of paper grade (stock) compositions of fluorescent whitening agents is physical agitation, the paper grade (stock) compositions of fluorescent whitening agents prepared promotes high to the whiteness value of stationery, when stationery brightens the whiteness requirement reaching identical, white dyes consumption can be reduced, cost-saving.
Description
Technical field
The present invention relates to white dyes, more specifically relate to a kind of paper grade (stock) compositions of fluorescent whitening agents and preparation method thereof.
Background technology
White dyes is commonly called as white dye, and be a kind of colourless and can inspire the organic compound of fluorescence under UV-irradiation, it can improve whiteness and the gloss of material.White dyes after composite have reduce white dyes usage quantity, strengthen the remarkable advantage such as whitening effect after using.
White dyes is effective mainly through chemical compounding and these two kinds of methods of physical compounding.Wherein chemical compounding is that the compound of several structural similitude is formed composite whitening agent after necessarily comparing mixing; Physical compounding is divided into three kinds: composite, the white dyes of composite, the white dyes of different white dyes and plastics additive and the composite of sensitizing dye.Patent CN102898870A discloses a kind of cotton white dyes, is mixed formed by white dyes BA, 63 DISPERSE Violet 63 2RL, disperse blue E-4R, Sodium sulfate anhydrous.min(99).Select suitable sensitizing dye and white dyes to combine, the result of use of white dyes can be improved, reach the object improving whiteness, reduce white dyes consumption.
In order to improve the whiteness value of stationery, be necessary to produce a kind of compositions of fluorescent whitening agents being exclusively used in stationery.
Summary of the invention
The technical problem solved: conventional white dyes whitening effect is poor, the problem that usage quantity is large.
Technical scheme: the invention discloses a kind of paper grade (stock) compositions of fluorescent whitening agents, be made up of according to weight part following composition: white dyes JD-3 is 0.5 ~ 1.0 part, Wet Strength Resin is 0.6 ~ 1.0 part, EX-SF DISPERSE BLUE EX-SF 300 RD is 0.02 ~ 0.1 part, sodium sulfate is 0.003 ~ 0.02 part, water is 90 ~ 100 parts.
The preparation method of paper grade (stock) compositions of fluorescent whitening agents, comprise the steps white dyes JD-3 to be 0.5 ~ 1.0 part, Wet Strength Resin is 0.6 ~ 1.0 part, EX-SF DISPERSE BLUE EX-SF 300 RD is 0.02 ~ 0.1 part, sodium sulfate is 0.003 ~ 0.02 part, water is 90 ~ 100 parts, stir, mixing speed is 60 ~ 90rpm, churning time is 0.5 ~ 1h, and temperature of reaction is room temperature.Stirring terminates rear gained solution and is desired product.
A kind of paper grade (stock) compositions of fluorescent whitening agents, white dyes JD-3 is preferably 0.8 part
.
A kind of paper grade (stock) compositions of fluorescent whitening agents, Wet Strength Resin is preferably 0.8 part.
A kind of paper grade (stock) compositions of fluorescent whitening agents, described Wet Strength Resin is polyamideepichlorohydrin.
Beneficial effect: the paper grade (stock) compositions of fluorescent whitening agents whitening effect that the present invention prepares is good, under reaching identical whiteness compared to similar whitening agent, usage quantity reduces, and cost reduces.

By paper grade (stock) compositions of fluorescent whitening agents prepared by embodiment 1, embodiment 2, embodiment 3, by dip method under the condition of 2 ‰ (owf) dye level, bath raio 1:40, contaminate 30 minutes for 80 DEG C, the result contaminating paper with white dyes JD-3 is as shown in the table.
| White dyes JD-3 | Embodiment 1 | Embodiment 2 | Embodiment 3 | |
| CIE whiteness value | 125.6 | 143.8 | 139.2 | 141.3 |
As can be known from the above table, paper grade (stock) compositions of fluorescent whitening agents of the present invention promotes high to the whiteness value of stationery, and result of use is better than white dyes JD-3.
