Abstract
The invention discloses a raw material and a method for preparing a papermaking cooking auxiliary agent. The raw material comprises the following materials in parts by weight: 20-30 parts of alkyl sulfonic acid, 10-15 parts of primary alcobol ethoxylate, 1-2 parts of isooctyl polyoxyethylene ether, 2-3 parts of sodium hydrogen sulfate, 5-8 parts of nonylphenol polyoxyethylene ether sodium sulfonate, 5-10 parts of quinone derivative A, 5-6 parts of oleamide, 0.5-1 part of alkyl sulfonamide sodium acetate, 1-2 parts of 2-naphthalenesulfonic acid, 0.3-0.4 part of sodium pyrophosphate, 40-50 parts of deionized water, 0.2-0.3 part of an emulsifier and 0.2-0.4 part of a thickening agent. Due to introduction of active groups, cooking liquor is accelerated to permeate into raw materials, dispersion and dissolution of lignin are promoted, and removal of intercellular layer lignin is intensified, so that the separation point of fibers is advanced, the effective cooking time is shortened, the fiber strength is remained, and the yield and the bleaching whiteness of the paper pulp are improved. Moreover, because the content of alkalis in waste liquor is low, the treatment difficulty of later wastewater is lowered, so that the discharged wastewater easily meets the environment-friendly requirement.
