Anti-ultraviolet (UV) water-based paper impregnant and preparation method thereof

Abstract

The invention relates to an anti-ultraviolet (UV) water-based paper impregnant, a preparation method of the impregnant and anti-UV water-based paper, and belongs to the paper processing field. The anti-ultraviolet water-based impregnant contains the following ingredients: an impregnation solution, a UV absorbent and a light stabilizer. The preparation method of the anti-UV water-based impregnant comprises the following steps: providing the impregnation solution; preparing the UV absorbent and the light stabilizer into a pre-dissolving solution; and adding the pre-dissolving solution into the impregnant under the stirring state. The preparation method of the anti-UV water-based paper comprises the following steps: preparing the anti-UV water-based paper impregnant; providing textured paper, impregnating both sides of the textured paper in the anti-UV water-based paper impregnant. According to the anti-UV water-based paper impregnant, the impregnant preparation method and the anti-UUV water-based paper, the anti-UV additive and light stabilizer are added into the impregnant, so that a good anti-UV function is given to the prepared textured paper; and meanwhile, by utilizing the impregnant, the production process can be simplified, and the secondary coating cost can be reduced.

Description

technical field [0001] The invention relates to an anti-UV water-based paper impregnating agent, a preparation method of the impregnating agent and an anti-UV water-based paper, belonging to the field of paper treatment. Background technique [0002] Masking tape (MASKINGTAPE) is a roll-shaped adhesive tape made of masking paper and pressure-sensitive glue as the main raw materials. The pressure-sensitive adhesive is coated on the masking paper, and the other side is coated with anti-sticking material. High temperature, good resistance to chemical solvents, high adhesion, soft fit and no adhesive residue after tearing, the industry is commonly known as masking paper pressure-sensitive adhesive tape. Masking tape is generally composed of base paper, impregnation treatment agent, anti-adhesive agent and pressure-sensitive adhesive. The preparation process of the masking tape is as follows: the base paper (masking paper) is impregnated to obtain impregnated paper, and the impre...

AI Technical Summary

Problems solved by technology

Existing masking tapes do not have anti-UV function, but there is also a layer of anti-UV layer coated between the base material and the release layer so that the tape has anti-UV function, but this method is in the process of production. In the process, a layer of anti-UV layer should be coated on the base material first, and then the release layer should be coated. During production, it will be coated twice, which will increase the production process and cost, and reduce the physical properties of the base material.
