Embodiment

[0030] Embodiment: The present invention provides a technical solution: a high-strength special paper processing technology, including the following steps:

[0031] S1. Prepare raw materials:

[0032] Prepare the following ingredients by weight:

[0033] 70-85 parts of softwood pulp fiber, 50-60 parts of bean protein mixed fiber, 45-50 parts of high-strength and high-modulus polyvinyl alcohol fiber, 15-30 parts of water-soluble polyvinyl alcohol fiber, 1-1.5 parts of dispersant and appropriate amount of water;

[0034] S2, preparation of fiber slurry:

[0035] Cut softwood pulp fiber and bean protein mixed fiber to 0.5mm-5.0mm successively;

[0036] Cut high-strength and high-modulus polyvinyl alcohol fibers and water-soluble polyvinyl alcohol fibers to 2-5.0 mm;

[0037] Putting the coniferous wood pulp fiber and the bean protein mixed fiber into a pulper for pulping to obtain the mixed fiber protoplasm of the coniferous wood pulp fiber protoplasm and the bean protein mixe...

Abstract

The invention discloses a high-strength special paper processing technology, including three steps of S1, preparation of raw materials, S2, preparation of fiber slurry and S3, and preparation of finished products, and then by selecting coniferous wood pulp fiber, bean protein mixed fiber, High-strength and high-modulus polyvinyl alcohol fibers and water-soluble polyvinyl alcohol fibers are mixed with plant fibers and synthetic fibers as raw materials, and combined with operations such as pulping and beating molding, so that pulp fibers can form hydrogen bonding forces and improve pulp fiber retention. The deposition rate, thereby enhancing the papermaking performance and paper strength of special paper.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a high-strength special paper processing technology. Background technique [0002] Specialty paper is a general term for a class of paper with special uses relative to ordinary paper. Special paper has been widely used in light industry, textile, food, water conservancy, electric power, telecommunications, transportation and construction industries. Special paper for speakers, packaging cardboard, liquid filter cardboard, water-soluble paper, fruit bag paper, straw paper, mulch paper, etc. [0003] The paper strength of special paper in the prior art is insufficient, which greatly limits the application and performance of special paper. For this reason, the present invention proposes a high-strength special paper processing technology capable of solving the above-mentioned problems. Contents of the invention [0004] The purpose of the present invention is to provide a h...
