Problems solved by technology

[0005] The technical problem to be solved by the present invention: for the slow penetration of the raw materials by the currently used pulping aids, the decomposition and dissolution of lignin takes a long time, resulting in low pulp yield, and the generation of difficult-to-handle black waste liquid, which causes serious pollution after discharge Due to the disadvantages of the environment, a kind of helicase obtained from the snail digestive juice is provided for use, and then the lard is collected by baking, and the castor oil is extracted by the fat absorption method, and the soft softener is obtained by blending with polyacrylamide and white clay, and then the The spare enzyme liquid and softener are mixed, fermented and reacted under the action of microorganisms, and pulping aids are obtained

Abstract

The invention discloses a preparation method of a special environment-friendly straw pulping auxiliary for papermaking, and belongs to the technical field of preparation of straw pulping auxiliaries. The preparation method comprises the following steps: separating helicase from digestive juice of snail for subsequent use; baking to collect lard oil; extracting castor oil by using a fat absorbing method; blending the castor oil with polyacrylamide and white earth to obtain a softener; mixing standby helicase liquid with the softener; and carrying out fermenting reaction under the effect of microorganisms to obtain the pulping auxiliary. The prepared pulping auxiliary can rapidly permeate into straw fibers, mobility of cellulose chains is improved under the effect of the softener, change of an ordered structure is facilitated, the concentration of intermolecular hydrogen bonding of cellulose is increased, and most of lignin and part of hemicellulose in a plant tissue are dissociated by the helicase, so that fibers are separated from one another; and formation of pulp is facilitated, pulp yield is improved, and the application prospect is wide.

Description

technical field [0001] The invention relates to a preparation method of an environmentally friendly straw pulping auxiliary agent specially used for papermaking, and belongs to the technical field of preparation of straw pulping auxiliary agents. Background technique [0002] my country's papermaking raw materials are extremely scarce, and wood, wood pulp, commercial pulp, waste paper and other papermaking raw materials rely heavily on imports, which seriously affects the safety of the papermaking industry; my country's straw resources are very rich, and its use in pulping and papermaking can greatly alleviate my country's papermaking. Raw material shortage situation. At present, the straw pulping technology includes expansion pulping technology, oxidation cleaning pulping technology, DMC pulping technology, etc., but these straw pulping and papermaking technologies have high energy consumption, heavy pollution, strong destructive power to fibers, and low pulp yield. questio...
