Abstract
The invention discloses a kind of preparation method of floatation waste paper composite deinking agent, kaolin and nano micro crystal cellulose are first subjected to solution blending, then by monomer of butyl methacrylate, benzoyl peroxide be initiator, N, N methylene-bisacrylamides are that crosslinking agent carries out graft crosslinking kaolin/microcrystalline cellulose/polybutyl methacrylate organic-inorganic hybrid material is made, with composite deinking agent is made after the composition such as surfactant compounding.The waste paper composite deinking agent that preparation method of the present invention is obtained has excellent absorptive collection ability to granule foreigns such as ink, improves the flotation collecting effect of deinking agent, is adapted to floatation deinking technique.
Description
Technical field
The present invention relates to deinking technical field, more particularly to a kind of preparation side of floatation waste paper composite deinking agent
Method.
Background technology
Deinking is exactly by printing-ink and fiber separation, so as to return by comprehensive functions such as chemicals, mechanical forces
The technique of collection slurry.Floatation is the main method of current deinking slurrying, and its principle is the different surfaces by variable grain
The purpose of separation can be reached.Wherein, the selection of deinking agent is to influence an important step of floatation and ink removing effect.Deinking agent
Effect is by ink emulsification, departs from fiber, and prevents it to be attached to again on fiber, conventional deinking agent be surfactant and
The compound of inorganic medicine.But the powder collection ability of surfactant is generally poor, accordingly, it would be desirable to explore significantly more efficient
Deinking agent.
Document《Improvement of the kaolinite soil matrix chemicals to deinking》Utilize modified kaolin and surfactant composition one
New deinking agent is planted, the flotation collecting effect of deinking agent is improved, is more efficiently separated and removes ink, dust in waste paper
With gluing composition granule.However, single kaolin is limited in one's ability to the absorptive collection of the granule foreigns such as ink as adsorbent, need
Further exploitation.
The content of the invention
The object of the invention be exactly in order to make up the defect of prior art there is provided it is a kind of it is high to ink adsorptivity, while flotation
The preparation method of the excellent floatation waste paper composite deinking agent of collecting effect.
The present invention is achieved by the following technical solutions：
A kind of preparation method of floatation waste paper composite deinking agent, comprises the following steps：
（1）10-15 parts by weight kaolin clay and 0.5-1 weight account polyethylenes alcohol are first added into 40-60 parts by weight nano microcrystalline fibers
1-2h is stirred in 85-95 DEG C in the plain aqueous solution, 3-5 weight parts of methacrylic acid butyl ester, 0.03- are then added under nitrogen protection
0.05 parts by weight benzoyl peroxide and 0.03-0.05 parts by weight N,N methylene bis acrylamide are in 70-80 DEG C of stirring reaction
2-4h, with being dried after absolute ethyl alcohol and distillation water washing, grinding uniform, obtains composite granule；
（2）By 10-15 parts by weight steps（1）Obtained composite granule and 10-20 parts by weight sodium sulfate of polyethenoxy ether of fatty alcohol,
5-10 parts by weight sodium lignin sulfonate, 1-2 parts by weight Tween-80s are added in blender stir in order, obtain
Floatation waste paper composite deinking agent.
The solid content of the nano micro crystal cellulose aqueous solution is 10-20%.
The molecular weight of the polyvinyl alcohol is 800-10000.
The kaolin is 300-400 mesh.
The step（2）Stirring condition be：30-35 DEG C of whipping temp, speed of agitator 400-600r/min.
It is an advantage of the invention that：
Kaolin and nano micro crystal cellulose are first carried out solution blending by the present invention, then by monomer of butyl methacrylate,
Benzoyl peroxide is that initiator, N,N methylene bis acrylamide are that crosslinking agent carries out graft crosslinking kaolin/crystallite is made
Compound deinking is made after cellulose/polybutyl methacrylate hybrid inorganic-organic materials, with the composition such as surfactant compounding
Agent.The present invention first compounds kaolin and microcrystalline cellulose as adsorbing base, is then grafted with butyl methacrylate
It is cross-linking modified to assign high absorption property of the material to low pole organic matter, so as to improve the adsorption capacity to ink；And formed
Composite there is porous network structure, be conducive to the collection of the granule foreigns such as ink, what preparation method of the present invention was obtained answers
Closing ink absorbent has excellent absorptive collection ability to granule foreigns such as ink, improves the flotation collecting effect of deinking agent, fits
Close floatation deinking technique.
