Description
Technical field
The present invention relates to a kind of deinking agent, be specially a kind of wastepaper deinking agent and preparation technology.
Background technology
Along with the continuous exhaustion of international or even domestic paper making raw material-forest reserves, for preserving the ecological environment to greatest extent
And the forest reserves, the primary raw material as papermaking that recycles of secondary stock is originated, is used forest reserves system by pulping and paper-making
Slurry, the enterprise of papermaking also develop to the recycling direction of deinking secondary stock.The domestic slurrying of existing 20%, papermaking
Enterprise is deinking slurrying, papermaking from utilizing Plant fiber's slurrying, papermaking transition.Most of domestic deinking agents have been not suitable with quiet
Electricity printing-ink, laser printing ink, the removal of plastic-coated ink, deinking office waste paper becomes secondary stock slurrying, paper technology
Bottleneck.
Summary of the invention
It is an object of the invention to provide a kind of wastepaper deinking agent and preparation technology, there is low cost, ink clearance
Relatively advantages of higher.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is: a kind of wastepaper deinking agent, often
Containing following raw material by weight in 1000 parts of deinking agents: sodium alkyl benzene sulfonate 18-20 part, sodium lauryl sulphate 80-
84 parts, carboxymethyl cellulose 12-12.5 part, sheet alkali 30-35 part, cocoanut fatty acid diethanolamide 68-70 part, ethylene glycol fourth
Ether 4-8 part, remaining composition are water.
This formula, infiltration moistening to the ink being attached on fiber can accelerate deinking agent pair rapidly by addition sheet alkali
The removal effect of ink；Sodium alkyl benzene sulfonate, sodium lauryl sulphate, cocoanut fatty acid diethanolamide three kinds are high-efficiency activated
Agent has stronger removal effect to ink；Add butyl glycol ether and laser printing ink and paint class are removed ratio more thoroughly；Add
Enter carboxymethyl cellulose, by deinking agent ink of dissolution from fiber is rubbed, accelerate ink and separate with fiber.
Preferably in scheme, sodium alkyl benzene sulfonate 20 parts, sodium lauryl sulphate 84 parts, carboxymethyl cellulose 12 parts, sheet
35 parts of alkali, cocoanut fatty acid diethanolamide 68 parts, butyl glycol ether 6 parts.
The method of the deinking agent described in preparation, concretely comprises the following steps:
Add water in container, open stirring, be sequentially added into sodium alkyl benzene sulfonate, sodium lauryl sulphate, carboxylic the most in order
Methylcellulose, sheet alkali, cocoanut fatty acid diethanolamide and butyl glycol ether, continue stirring more than 4 hours, i.e. after adding
Obtain wastepaper deinking agent.If it is uneven in the dispersion of reactor endoparticle that addition misprogramming easily causes deinking agent, impact
Deinking efficiency.
Water crosses 100 mesh sieves before addition, and is heated to 40 DEG C-45 DEG C.Water is filtered, can effectively prevent in clear water
Impurity enter deinking agent reactor cause deinking agent unclean, such as blackyellow dust；And temperature controls to be because in this temperature
Each composition rate of dispersion of lower deinking agent is comparatively fast and very uniformly, the too high meeting of temperature causes the volatilization of part deinking agent composition to slacken de-
Ink effect.
After cocoanut fatty acid diethanolamide adds, stirring adds butyl glycol ether in 3 hours, and remaining every kind material adds
All stir 10min after entering and add another kind of material.Owing to cocoanut fatty acid diethanolamide adds deinking agent reactor
Rear viscosity improves rapidly, have thickening power to be difficult to other composition uniformly mixes, so to keep longer mixing time；Other
Composition rate of dispersion is comparatively fast without long agitation.
Deinking Pulp prepared by the deinking agent described in employing, every 1000 parts of raw materials are calculated as by weight: deinking agent 8-10 part, dense
Degree is Caustic soda 40-50 part, sodium silicate 50-60 part of 30%, water 720-760 part.
The ink being attached on fiber can be moistened rapidly by soda bath, infiltration, accelerates the deinking agent removal to ink
Effect, ink rapid adsorption that deinking agent can be separated from fiber by sodium silicate, parcel, effectively prevent ink from returning dye fibre
Dimension.
The temperature of described water controls as 92-96 DEG C.
The method that Deinking Pulp described in employing carries out deinking to wastepaper, comprises the following steps:
First in hydrabrusher, it is proportionally added into water, then according to proportioning adds deinking agent, Caustic soda, sodium silicate, makes deinking
Slurry, opens hydrabrusher and puts into wastepaper 1160-1180 part, adds hydrogen peroxide 40-45 part, control after 30-40 minute
PH value, at 12-14, continues reaction 10-12 minute, adds Pulvis Talci 5-8 part, and blowing after reacting 5-7 minute, by Deinking Pulp
Fiber separates the deinking process that can complete wastepaper with deinking wastewater.
Described wastepaper rejects kraft paper, overlay film paperboard, chromatics paper, heat-sensitive paper and impurity.
The deinking agent that the present invention provides is milky paste, and solid content is 30wt%, strong basicity, is corrosive skin；Its
Cost reduces, and often the cost of one ton of deinking agent of preparation is about 2577 yuan, uses this deinking agent that wastepaper is carried out deinking, the most de-
Ink agent one is compared other domestic deinking agent cost and can be reduced about 38 yuan, and remaining raw material also can reduce accordingly, per ton de-
Ink slurry chemicals integrated cost can reduce by 80 yuan.And Deinking Pulp whiteness reaches 85% after using this deinking agent.
This deinking agent solves electrostatic printing ink, laser printing ink, plastic-coated ink and the sicker in waste paper to be difficult to point
The process difficulties separated out, carries out scientific compatibility according to the not same-action of raw materials various to office waste paper deinking agent and realizes electrostatic
Printing-ink, laser printing ink, plastic-coated ink are thoroughly removed；And the deinking agent researched and developed energy during deinking office waste paper
Enough make sicker easily remove when being separated into the granule of different-grain diameter by pressurized screen and desander, there is low cost, ink goes
Except the higher feature of rate.
