Problems solved by technology

However, the strong photocatalytic activity of nano-oxides will affect the performance of the loaded object, so it must be surface treated to reduce its photocatalytic performance and improve its dispersion performance in organic solvents
[0004] In recent years, nano-oxides have been widely used in rubber, plastics, inks, coatings and other industries, but there are few applications in the pre-protection of paper printed products.

preparation example Construction

[0034] The preparation method of the multi-functional protective liquid for paper printed products includes firstly mixing the nano-oxide with a part, adding a dispersant, and then ultrasonically dispersing, and the dispersion time is 10-25 minutes to obtain a dispersion liquid of the nano-oxide.

[0035] Heat the remaining solvent to the dissolution temperature of the cellulose organic matter, and gradually add the cellulose organic matter until it dissolves under the condition of high-speed stirring, the stirring speed is 1000-1400 rpm, and the stirring time is 60-120 minutes to obtain the cellulose organic solution.

[0036] The application method of the multifunctional protective liquid for paper-based material printed matter of the present invention is divided into two types: one is a mixed coating method, and the mixed coating method directly mixes the dispersion liquid of nano-oxides with the cellulose organic matter solution at room temperature, Mix evenly by stirring ...

Embodiment 1

[0038] 1) Preparation method:

[0039] Add 0.4g of nano-titanium dioxide to 47.58g of absolute ethanol, and add 0.02g of Tween-80, and ultrasonically disperse for 15 minutes to obtain a dispersion of nano-titanium dioxide; take another 50g of absolute ethanol, heat it to 60°C, and add it while stirring 2.0 g of hydroxypropyl cellulose, the stirring speed is 1200 rpm, and the stirring time is 100 minutes, so that the hydroxypropyl cellulose is completely dissolved.

[0040] 2) Application method:

[0041] The hydroxypropyl cellulose solution obtained in 1) is coated on the surface of the paper print, and after it is completely dry, the nano titanium dioxide dispersion is coated thereon. Coating method Use a laboratory sizing machine to coat the surface of the printed matter and let it dry naturally.

Embodiment 2

[0043] 1) Preparation method:

[0044]Add 0.4g of nano-titanium dioxide to 47.58g of absolute ethanol, and add 0.02g of Tween-80, and ultrasonically disperse for 15 minutes to obtain a dispersion of nano-titanium dioxide; take another 50g of absolute ethanol, heat it to 60°C, and add it while stirring 2.0 g of hydroxypropyl cellulose, the stirring speed was 1200 rpm, and the stirring time was 100 minutes to obtain a hydroxypropyl cellulose solution.

[0045] The nano-titanium dioxide dispersion liquid is directly mixed with the hydroxypropyl cellulose solution, and the mixture is uniformly dispersed by stirring, the stirring speed is 1200 rpm, and the stirring time is 40 minutes, and the protective liquid is obtained.

[0046] 2) Application method:

[0047] Apply the protective solution obtained in 1) on the surface of the printed matter using a laboratory sizing machine, and let it dry naturally.

Abstract

The invention discloses a multifunctional protective liquid for paper-based material printed matters, which includes, by mass, 0.2-2.0% of a nano oxide, 0.01-1.0% of a dispersant, 1.0-5.0% of a cellulose-type organic substance, and 92.9-98.79% of a solvent, the sum of the mass percentages of all the components is 100%. An application method includes the steps of: uniformly mixing a dispersion liquid of the nano oxide with the cellulose-type organic substance and directly coating the surface of the paper printed matters with the mixture; or firstly coating the surface of the paper printed matters with the cellulose-type organic substance, naturally drying the paper printed matters in air, and then coating the paper printed matters with the dispersion liquid of the nano oxide. The multifunctional protective liquid is prepared with the nano oxide, the cellulose-type organic substance, the dispersant, and the solvent ethanol as main raw materials and is used for the paper-based material printed matters. The multifunctional protective liquid has simple formula, is environment-friendly and toxic-free and has good pre-protective effect on the paper printed matters.

Description

technical field [0001] The invention belongs to the technical field of protection of paper-based printed matter, and in particular relates to a multifunctional protective liquid for printed matter of paper-based materials, and also relates to the application of the protective liquid. Background technique [0002] Since the invention of printing, printed matter has played the role of an important cultural information transmission medium for human beings. At present, as one of the carriers of human spiritual food, it also plays an irreplaceable role in meeting people's growing spiritual life needs, especially personalized color printed matter. Usually, after being placed for a long time, printed matter will be affected by factors such as temperature, light, humidity, etc., and it is easy to turn yellow and become brittle, which will affect its use, viewing and preservation value. Especially paper artworks are sensitive to the external environment and need to be protected from...
