Embodiment 1

[0028] (1) Under stirring, stir and mix 3kg of stearic acid, 1kg of edible alkali and 1kg of borax to obtain a paraffin emulsifier. After melting 10kg of paraffin, add paraffin emulsifier, and add 5kg of cationic starch and 8kg of rosin at 40℃. Obtain mixed liquid 1, add the mixed liquid 1 to 60 kg of pulp fibers, stir uniformly and dry to obtain base paper;

[0029] (2) Mix 7kg of water-based ink and 0.1kg of thickener to obtain mixed liquid 2, coat the mixed liquid 2 on the surface of the base paper, and pass the base paper through a drying tunnel at a temperature of 150°C at a speed of 2m / min;

[0030] (3) Mix 0.5kg of ten thousand rubber nanofiber powder, 0.1kg of aluminum sulfate and 3kg of dimethylformamide to obtain a mixed solution 3, spray it on the surface of the base paper just coming out of the drying tunnel in step (2), and then spray it at 8m / min Speed ​​through a drying tunnel at a temperature of 70°C to obtain an anti-mold and anti-bacterial decorative paper.

Embodiment 2

[0032] (1) Under stirring, stir and mix 4kg stearic acid, 0.5kg edible alkali and 0.5kg borax to obtain a paraffin emulsifier. After 22kg of paraffin is melted, add the paraffin emulsifier, and add 10kg cationic starch, 5kg of rosin obtains mixed solution 1, adding this mixed solution 1 to 80kg of pulp fiber, and stir evenly to obtain base paper;

[0033] (2) Mix 9kg of water-based ink and 0.2kg of thickener to obtain mixed liquid 2, coat the mixed liquid 2 on the surface of the base paper, and pass the base paper through a drying tunnel with a temperature of 160℃ at a speed of 3m / min;

[0034] (3) Mix 0.9kg of ten thousand rubber nanofiber powder, 0.3kg of aluminum sulfate and 1kg of dimethylformamide to obtain a mixed solution 3, spray it on the surface of the base paper just coming out of the drying tunnel in step (2), and then spray it at 6m / min Speed ​​through a drying tunnel with a temperature of 80°C to obtain anti-mold and anti-bacterial decorative paper.

Embodiment 3

[0036] (1) Under stirring, stir and mix 2kg stearic acid, 0.8kg edible alkali and 0.8kg borax to obtain a paraffin emulsifier. After melting 10-22 parts of paraffin wax, add paraffin emulsifier and add 8kg at 45℃. Cationic starch and 6 kg of rosin are used to obtain mixed solution 1. Add the mixed solution 1 to 70 kg of pulp fibers and stir to obtain base paper;

[0037] (2) Mix 8 kg of water-based ink and 0.15 kg of thickener to obtain mixed liquid 2, coat the mixed liquid 2 on the surface of the base paper, and pass the base paper through a drying tunnel at a temperature of 155°C at a speed of 2m / min;

[0038] (3) Mix 0.8kg of ten thousand rubber nanofiber powder, 0.2kg of aluminum sulfate and 2kg of dimethylformamide to obtain a mixed solution 3, spray it on the surface of the base paper just coming out of the drying tunnel in step (2), and then spray it at 7m / min Speed ​​through a drying tunnel at a temperature of 75°C to obtain an anti-mold and anti-bacterial decorative paper....

Abstract

The invention provides mould-proof antibacterial decorative paper and a preparation method thereof. Part of paraffin is added into base paper, and as the paraffin has a good waterproof effect, moisture is effectively prevented from permeating in the base paper in a humid environment; furthermore, in the preparation of an ink layer on the surface of the base body, by controlling the drying speed by stages, part of the paraffin in the base paper melts and permeates into the ink layer while ink permeates into the fiber of the base paper in a 150-160 DEG C drying tunnel; by combined action of the charge force of other substances, mixed liquor containing nano fibers is sprayed onto the surface of the ink layer, and in the further drying process, the nano fiber can tightly adhere to a mixed layer formed by the ink layer and the paraffin; therefore, the decorative paper has good hydrophobic, humidity resistant, sterilizing and mould proof effects.

Description

Technical field [0001] The invention belongs to the field of decorative paper, and particularly relates to an anti-mold and antibacterial decorative paper and a preparation method thereof. Background technique [0002] The current decorative paper mainly has a two-layer structure, that is, it is composed of a base paper and an ink layer on the front side. When in use, the back side of the base paper is pressed on a substrate, and the substrate is mainly a wood or fiber substrate. [0003] In the aspect of anti-mold and anti-bacterial aspects of the existing decorative paper, an anti-mold or anti-bacterial agent is usually added to the ink layer coated on the surface of the decorative paper. However, in the actual application process, when this kind of decorative paper is used for a period of time, the surface material will be lost or peeled off during the contact with the outside world, which leads to the problem of mildew on the part of the paper surface after peeling off; in addi...
