| description | 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 fib |
