Abstract

The invention discloses a kind of paper deinking agent and preparation method thereof, the invention belongs to field of papermaking.This paper deinking agent is made up of the component comprising following weight part: by cationic polyacrylamide 40-50 part, attapulgite 20-30 part, sodium polyacrylate 15-20 part, sodium alginate 10-15 part, glycerol 10-12 part, sodium laurylsulfonate 5-12 part and sodium-chlor 2-5 part.The paper deinking agent obtained by the present invention has good deinking efficiency paper deinking agent, because this deinking agent is in use without the need to adding strong acid and strong base substance, has fewer environmental impacts.

Description

A kind of paper deinking agent and preparation method thereof

Technical field

The invention belongs to field of papermaking, particularly a kind of paper deinking agent and preparation method thereof.

Background technology

The Main Function of deinking agent destroys ink to the bonding strength of paper fibre, ink peeled off from fiber, is dispersed in water.Deinking agent generally has moistening, infiltration, swellable resins, the several functions such as emulsification and dispersion.Deinking agent is mainly divided into floatation deinking agent and washout algorithms agent.Floatation deinking agent is most widely used general and the most effective deinking agent during current deinking is produced.Floatation deinking agent mainly comprises negatively charged ion fatty acid soaps class and surfactant compound class deinking agent.

In recent years, the deinking agent of vast researcher exploitation mainly negatively charged ion and the composite class of nonionogenic tenside, biological enzyme and mineral material and fatty acid, nonionic fatty alcohols class and fatty ethers, compound surfactant class, biological enzyme etc.

Summary of the invention

For above-mentioned demand, the object of this invention is to provide a kind of paper deinking agent and preparation method thereof, use this deinking agent can obtain good deinking efficiency, simultaneously because this deinking agent is in use without the need to adding strong acid and strong base substance, less on the impact of environment.

Object of the present invention can be achieved through the following technical solutions:

A kind of paper deinking agent, be made up of the component comprising following weight part:

Described component also comprises 0-5 weight part ethylene glycol.

Described component also comprises 0-5 weight part polyoxyethylene glycol.

A preparation method for paper deinking agent, the method comprises the following steps:

(1) cationic polyacrylamide 40-50 weight part, attapulgite 20-30 weight part, sodium polyacrylate 15-20 weight part, sodium alginate 10-15 weight part, sodium-chlor 2-5 weight part and polyoxyethylene glycol 0-5 weight part are added three leaves and advance agitator, mix with the rotating speed of 700 revs/min;

(2) mixture of sodium laurylsulfonate 5-12 weight part, glycerol 10-12 weight part and ethylene glycol 0-5 weight part is added in the product of step (1), send into three leaf propeller agitators, at 60-80 DEG C, with the rotating speed mixing 1-2 hour of 700 revs/min, obtain paper deinking agent.

Mixing temperature in described step (1) is 60-90 DEG C.

Beneficial effect:

The present invention adopts cationic polyacrylamide, attapulgite effectively can will be attached to the ink wash-out on paper, and adding sodium polyacrylate, sodium alginate and glycerol makes deinking agent have certain moistening function, add sodium laurylsulfonate and sodium-chlor simultaneously and on the one hand promoter action is served for the wash-out of the color of ink, accelerate elution rate.
