Environment-friendly pulping agent and process

Abstract

The environment friendly pulping agent is prepared with the materials including animal oil 8-12 wt%, sodium dodecyl benzene sulfonate 28-32 wt%, hydrogen peroxide 38-42 wt%, sodium sulfite 13-17 wt% and potassium ferricyanide 3-8wt%, and through the saponification reaction between animal oil and hydrogen peroxide, and the further mixing with the other materials. The pulping process with the pulping agent includes the steps of spraying and soaking, extruding pulp, milling after adding water, extruding pulp, milling after adding acid, sieving, washing and bleaching. The environment friendly pulping agent has short grass material soaking time, capacity of being recovered for reuse and no environmental pollution.

Description

technical field

[0001] The invention belongs to the technical field of improvement of cold dipping pulping and papermaking technology, and specifically relates to an environment-friendly pulping agent and a process. Background technique

[0002] At present, due to the serious pollution of wheat straw pulping in my country, 90% of wheat straw pulping production lines have been shut down, a large number of pulping equipment has been left idle, and wheat straw has been wasted, resulting in huge economic losses.

[0003] my country is rich in gramineous plant resources, and gramineous plants are good raw materials for papermaking and an indispensable fiber for papermaking. Poaceae plants include wheat straw, straw, cotton stalks, reeds, bamboo, etc. Before the 20th century, wheat straw was the main source of fiber for papermaking in my country.
