Embodiment 1

[0027] This washi tape base paper is made of the following raw material proportions by weight: 70 parts of long-fiber wood pulp, 20 parts of short-fiber chemical-mechanical wood pulp, 0.5 part of wet strength agent, 20 parts of coated latex, and cork extract Liquid 5 parts.

[0028] Further, the long-fiber wood pulp is softwood wood pulp.

[0029] Further, short fiber chemical mechanical wood pulp is hardwood pulp.

[0030] Further, the coating latex is styrene-acrylic latex.

[0031] The production method of above-mentioned washi tape base paper, comprises the steps:

[0032] The first step is beating treatment. The long-fiber wood pulp and short-fiber chemical-mechanical wood pulp are fully mixed and then put into the hydraulic pulper and added with water for mixing and crushing treatment. In the pulp tank, two double-disk refiners are used in series for slight beating. The beating concentration is 3.0%, the beating degree is 15°, and the wet weight is 10g. After the beat...

Abstract

The invention relates to body paper of a washi adhesive tape. By taking long fiber wood pulp, short fiber chemical and mechanical pulp, a wet strength agent, coating latex and a golden cypress extraction solution as raw materials, the body paper of the washi adhesive tape is prepared by the steps of pulping treatment, addition of auxiliaries, supercooling treatment, papermaking treatment, coating treatment and paper forming. The body paper provided by the invention has the beneficial effects that the body paper has good dry and wet strength and delamination resisting strength, and good tear resistance, can satisfy the strength demands in subsequent processing and actual use, is not layered, and has good flexibility; the body paper has good water resistance and solvent resistance and excellent ultraviolet resistance and temperature resistance, and can be used for reducing aging of the washi adhesive tape and prolonging the service life of washi adhesive tape; the body paper has good surface smoothness, so that production and processing of the adhesive tape are facilitated.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a washi tape base paper and a production method thereof. Background technique [0002] Washi tape base paper is a special technology supporting paper for the production of washi tape in the adhesive industry. Washi tape is mainly used for masking protection such as high-temperature baking paint and building decoration. Washi tape has gradually replaced traditional masking in industries such as baking paint and home decoration. Paper tape. [0003] Washi tape base paper has high performance requirements, complex manufacturing process, and high technical difficulty. At present, the base paper of washi tape on the market has disadvantages such as poor flexibility, poor UV resistance, water resistance, temperature resistance, and tear resistance. Therefore, , There is an urgent need for high-quality washi tape base paper in the market. Contents of the invention [0004] The p...
