High-strength bio-based degradable adhesive tape and preparation method thereof

The invention discloses a preparation method of high-strength bio-based degradable adhesive tape paper, which comprises the following operation steps: S1, proportioning: respectively blending 50-55% of natural color sulfate softwood pulp and 45-50% of natural color sulfate bamboo pulp according to respective proportions, and mixing together to form mixed pulp; s2, pulping the slurry; s3, pulping; s4, preparing pulp; s5, adding a chemical additive; s6, forming on a net; s7, the paper sheet strength and elasticity are improved; s8, carrying out water resistance and surface enhancement treatment on the paper; and S9, calendaring rectification treatment. The invention also provides the high-strength bio-based degradable adhesive tape paper prepared by the method. The prepared adhesive tape paper is good in tensile strength, excellent in breaking resistance and remarkable in waterproof, oil-proof and barrier effects, the processing requirements of degradable paper adhesive tapes can be met, and the preparation met
