Abstract
The invention discloses and a kind ofly improve the method for fluorescent whitening agent at paper surface whitening effectiveness, it comprises the steps: (1) in the liquid fluorescent whitening agent APC of 10-40%, adds the disperse violet of 0.01-6%, 0.01-4.0% dispersed blue dye is mixed with compositions of fluorescent whitening agents by mechanical agitation; (2) kaolin of 10-30% part, the calcium carbonate of 5-15% is taken again, add the benzene emulsion of 5-15%, the PVA aqueous solution 50-75% of 0.01-3% is added after stirring, add the compositions of fluorescent whitening agents 1-5% that step (1) prepares again, surface coating is carried out at the paper surface of manufacturing paper with pulp, dry under the drying condition of 105 DEG C, dry in the air to room temperature, obtain the paper of high whiteness.The inventive method is reasonable, simple to operate, high to the whitening effect raising efficiency of paper, the whiteness of paper surface can be made to be increased to 173% than body paper whiteness, increased substantially the whiteness effect of paper.
Description
Technical field
The present invention relates to and a kind ofly improve the method for fluorescent whitening agent at paper surface whitening effectiveness.
Background technology
The application mode of fluorescent whitening agent in papermaking have in slurry brighten, paper surface coating is brightened, paper for surface sizing brightens.General paper grade (stock) fluorescent whitening agent is liquid dosage form, has dissolubility good, is easy to the advantage that automation is added in application process.According in paper-making process, electric charge is on the impact of fluorescent whitening agent, general fluorescent whitening agent is in the process of paper application, fluorescent whitening agent disulfonic acid, tetrasulfonic acid is had, the fluorescent whitening agent tetrasulfonic acid applied in paper surface coating and top sizing and fluorescent whitening agent six sulfonic acid for what brighten in starching.The concentration brightened in slurry due to slurry is low, the good water solubility of fluorescent whitening agent, and when causing fluorescent whitening agent for brightening in starching, consumption is large, and it is low that the whiteness of paper promotes effect, and the utilization rate of fluorescent whitening agent is low.
Summary of the invention
The object of the present invention is to provide a kind of method reasonable, simple to operate, to the method for the high raising fluorescent whitening agent of the whitening effect raising efficiency of paper at paper surface whitening effectiveness.
The technical solution adopted in the present invention is:
Improve the method for fluorescent whitening agent at paper surface whitening effectiveness, it comprises the steps:
(1) in the liquid fluorescent whitening agent APC of 10-40%, add the disperse violet of 0.01-6% by mechanical agitation, 0.01-4.0% dispersed blue dye is mixed with compositions of fluorescent whitening agents;
(2) kaolin of 10-30%, the calcium carbonate of 5-15% is taken again, add the benzene emulsion of 5-15%, the PVA aqueous solution 50-75% of 0.01-3% is added after stirring, add the compositions of fluorescent whitening agents 1-5% that step (1) prepares again, surface coating is carried out at the paper surface of manufacturing paper with pulp, dry under the drying condition of 105 DEG C, dry in the air to room temperature, obtain the paper of high whiteness.
Further, the aqueous solution of the PVA aqueous solution of described 0.01-3% to be the degree of polymerization the be PVA of 1500-2000.
On year-on-year basis under condition:
(1) fluorescent whitening agent is not added;
(2) 1.2 part of 35% fluorescent whitening agent APC is added;
(3) 1.2 parts of compositions of fluorescent whitening agents A are added;
Carry out surface coating at the paper surface of manufacturing paper with pulp, dry under the drying condition of 105 DEG C, the CIE whiteness that records paper to room temperature on colour photometer of drying in the air is as shown in the table:
| Coating title | WI CIE | Remarks |
| Body paper | 69.06 | Without bodystock paper whiteness |
| Coating A | 68.08 | Not containing fluorescent whitening agent coating whiteness |
| Coating B | 104.92 | Containing fluorescent whitening agent, not containing dye-coating whiteness |
| Coating C | 117.86 | Containing the compositions of fluorescent whitening agents coating whiteness of dyestuff |
As can be seen from the table, on year-on-year basis under condition, body paper CIE whiteness than high by 0.96 containing the coating A whiteness of fluorescent whitening agent, the whiteness that reason is component kaolin in coating, calcium carbonate reduces paper; Containing fluorescent whitening agent, containing dyestuff coating B coating after paper CIE whiteness than containing fluorescent whitening agent coating A be coated with after Paper White Degree not high by 36.84; According to the coating C containing compositions of fluorescent whitening agents of the inventive method, the CIE whiteness of the paper after coating is not than high by 49.78 containing the Paper White Degree after the coating A coating of fluorescent whitening agent.
Show according to method provided by the present invention, paper is after surface coating is brightened, and the whiteness of paper is increased to 173% of sheet basis whiteness, and whiteness efficiency improves 73%.
Below in conjunction with embodiment, the invention will be further described.
