Abstract
The invention relates to a method for preparing high-performance macroporous adsorption resin, and belongs to the field of polymer chemistry. The method comprises the following steps: feeding pure water and a dispersing agent of polyvinyl alcohol into a reaction kettle firstly, heating with agitation to 50 DEG C, adding a mixture of divinylbenzene, pore-foaming agent solvent oil and initiator dibenzoyl peroxide, then heating to 70 DEG C, keeping the temperature for 2 hours, then heating to above 90 DEG C, keeping the temperature for 4-10 hours, then cooling to below 45 DEG C to obtain white balls, then performing a post crosslinking reaction for the white balls with a TX catalyst, discharging the white balls after the crosslinking reaction to a washing kettle for washing, and then drying, then adding the white balls and acetone to the reaction kettle, heating twice to 50 DEG C, keeping the temperature and reacting for 5 hours, and washing with water to obtain macroporous adsorption resin. The high-performance macroporous adsorption resin obtained by the present invention has the advantages of high mechanical strength, uniform structure, good chemical stability, and high anti-pollution and anti-oxidation ability.
Description
Technical field
The present invention relates to technical field of polymer chemistry, be specifically related to a kind of preparation method of high-performance macroporous adsorbent resin.
Background technology
Macroporous adsorbent resin is the polymeric sorbent that a class does not contain the macroporous structure of cation exchange groups.It is generally white spheroidal particle, physico-chemical property is stable, is insoluble to acid, alkali and organic solvent, and its adsorptivity is because the result of Van der Waals force or generation hydrogen bond, organism there is the separation and concentration effect, and is not subjected to the interference of inorganic salts and strong ion, low molecular compound.It has the better physical performance, can be repeatedly used, and regeneration is also than being easier to.Macroporous adsorbent resin is of wide application.Have a wide range of applications at aspects such as the purification of wastewater treatment, extract drugs, chemical reagent, medical analysis, acute drugs poisoning processing, chromatograms.Particularly special high-performance polymeric adsorbent has also been realized the resource utilization of refuse when waste water is effectively handled, should this be a much progress on the polymeric adsorbent development history.
Since the seventies in 20th century, along with the development of macroporous ion exchange resin, macroporous adsorbent resin arises at the historic moment.Along with the further intensification to macroporous adsorbent resin research, its application is also more and more widely also progressively goed deep into for its separating mechanism research aspect.Macroporous adsorbent resin is a kind of still at developing solid adsorbent.Macroporous adsorbent resin is used very extensive in wastewater treatment, be mainly used in containing in the waste water organism absorption and recovery of benzene ring structures such as benzene, chlorobenzene, phenol, aniline, Whitfield's ointment, naphthalene thiol, widespread use H103 in the market, this product value-rising height, but, it can produce a large amount of toxic gases in process of production, cause workman and the peripheral masses carcinogenic and unhealthful easily, so, many enterprises can't ordinary production or hide and produce in frequent replacing workman's mode in the mountain area, thereby have influenced its production and utilization greatly.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of preparation method of high-performance macroporous adsorbent resin, can realize nontoxic, tasteless, human body is not had injury, and the polymerization that increases monomer simultaneously increases the physical property of macroporous adsorbent resins such as specific surface area, control absorption aperture be narrow.
Technical problem to be solved by this invention realizes by the following technical solutions,
A kind of preparation method of high-performance macroporous adsorbent resin is characterized in that: its preparation method comprises the steps:
Step 1: polyreaction: in reactor, drop into pure water, polyethylene of dispersing agent alcohol, stirring is added divinylbenzene after being warming up to 50 ℃, pore-creating agent solvent oil and initiator dibenzoyl peroxide mixture, be warming up to 70 ℃ then, be incubated after 2 hours, be warming up to again more than 90 ℃, be incubated after 4-10 hour, the pore-creating agent solvent oil is reclaimed in condensation, is cooled to then below 45 ℃, obtains completely reacted Archon, be that catalyzer carries out the back crosslinking reaction to Archon then with TX, the Archon of back crosslinking reaction is discharged to washes in the material still, water cleans, and is limpid until water outlet, boil off the pore-creating agent solvent oil with steam then, and the oven dry Archon;
Step 2: aftertreatment: Archon and acetone are added in the reactor, be warming up to 50 ℃ through twice, insulation reaction is after 5 hours, water cleans, obtain macroporous adsorbent resin, the effect of acetone mainly is that Archon is fully expanded, and follow-up washing can be entered in the Archon space.
The invention has the beneficial effects as follows: the high-performance macroporous adsorbent resin physical strength height that the present invention makes, even structure can be cleaned after the absorption fully, does not produce accumulation, can control pore size artificially; It is good to have chemical stability, antipollution, advantage such as resistance of oxidation is strong; And be catalyzer with novel material TX, can realize in process of production nontoxic, tasteless, human body is not had injury.
