Abstract
The invention relates to a cooking auxiliary agent for papermaking and pulping, belongs to the field of papermaking, and aims to solve the problems that the existing cooking auxiliary agent is high in toxicity and severe in environmental pollution. The cooking auxiliary agent for papermaking and pulping comprises the following components in percentage by weight: 8-12% of primary alcobol ethoxylate, 10-20% of linear alkylbenzene sulfonates, 3-8% of alkyl sulfonate sodium acetate, 3-8% of alkyl phenyl polyoxyethylene ether, 2-5% of sodium nonylphenol polyoxyethylene ether sulfonate, 1-3% of methyl sulfone, 2-5% of carboxymethyl cellulose, 0.5-1.2% of oleamide, 0.1-0.5% of sodium pyrophosphate and the balance of deionized water. The cooking auxiliary agent is mainly applicable to the papermaking field, can reduce environmental pollution, improve the screened pulp yield and reduce Kappa number.
Description
Technical field
The present invention relates to a kind of paper-making pulping digesting assistant, belong to field of papermaking.
Background technology
In chemical pulping process, digesting assistant affects to a great extent the speed of delignification, the quality of pulping, paper pulp yield, and affects the effect of postorder bleaching.Current most of slurrying enterprise is used akali sulphide, and part is used anthraquinone and derivative thereof, but this class digesting assistant solubility property is poor, and slower to raw material infiltration, lignin decomposition and dissolution time are longer, and this has just caused the material removing easily by fiber, to be adsorbed once again, affects quality and the yield of slurry.In addition, this analog assistant has certain toxicity, and environmental pollution is large, and in pipeline, easily fouling, large to equipment corrosion.
Surfactant has effect and the function of the aspects such as washing, wetting, infiltration, dispersion, emulsification, softness, froth breaking.It can promote wetting to fibrous raw material of cooking liquor, accelerates the infiltration of boiling chemicals and other chemicals and evenly diffusion, thereby promotes cooking liquor to the removing of lignin and resin in timber or non-timber, and can also play the effect of dispersion resin.Adopt the composite of anion surfactant and non-ionic surface active agent, both can accelerate infiltration, promote removing of lignin and resin, can also improve paper pulp yield, many-sided quality of improving slurry, comprises the intensity that reduces Kappa number and improve slurry.
Summary of the invention
The object of the present invention is to provide a kind of paper-making pulping digesting assistant, safety non-pollution, can obviously shorten the digestion time of slurry, improves screened yield.
Described, paper-making pulping digesting assistant, is comprised of the component of following percentage by weight:
Fatty alcohol-polyoxyethylene ether 8-12%
Neopelex 10-20%
Alkyl sulfonamide sodium acetate 3-8%
Alkylphenol polyoxyethylene 3-8%
Polyoxyethylene nonylphenol ether sodium sulfonate 2-5%
Dimethyl sulfonic acid 1-3%
Sodium carboxymethylcellulose 2-5%

Deionized water surplus
The preparation method of digesting assistant for described paper-making pulping, comprises the following steps:
Deionized water is joined in reactor, be heated to 60-70 ℃, fatty alcohol-polyoxyethylene ether, neopelex, alkyl sulfonamide sodium acetate, alkylphenol polyoxyethylene, polyoxyethylene nonylphenol ether sodium sulfonate are dropped into reactor successively, under 60-70 ℃ of condition, stir 30-50 minute, then be cooled to 40-50 ℃, add dimethyl sulfonic acid, sodium carboxymethylcellulose, oleamide, sodium pyrophosphate, and at this temperature, stir 20-30 minute, cooling discharging.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention adopt anion and non-ionic surface active agent composite, in water, there is fabulous dispersiveness, improved the permeability of raw material, improved the uniformity of boiling, promote dispersion and the stripping of lignin; Surfactant has good emulsibility and diffusivity, after the colloid that can prevent from having deviate from, lignin, resin etc. are distributed in black liquor uniformly, by fiber, is adsorbed once again; Digesting assistant of the present invention has reduced amount of caustic soda, shortens digestion time 30-50 minute, steam saving consumption, screened yield improves 4-5%, Kappa number reduces 7-10, can part, replace akali sulphide, anthraquinone and derivative thereof even completely, solved to a great extent waste water pollution problem; Soft, loose with the slurry of digesting assistant boiling of the present invention, pulping is even, and black liquor is easy to extract, slurry floats and damages little, good springiness.
