Nanometer-scale particle recycled slurry paper

Abstract

The present invention discloses a nanometer-scale particle recycled slurry paper. The shares in weight of its ingredients are: papermaking wastewater slurry 20-80, pulp 20-80, nanometer-scale calcium carbonate 2-20, and chemical auxiliary agent performing the function of coacervation 1-5. The production technology process of the present invention is: slurry→pressing and squeezing the slurry→washing and filtering→putting into a pool→adding nanometer-scale calcium carbonate→mixing the paper pulp with the chemical auxiliary agent performing coacervation function→stirring and mixing→transferring onto a mesh→pressing and squeezing→drying→forming into paper→winding into reels.

We claim:
