Description
Technical field
The present invention relates to boron adsorbent preparation technical fields, and in particular to a kind of preparation method and use of super branched polyurethane
On the way.
Background technique
Boron, due to its between metal and it is nonmetallic between special physico-chemical property, be widely used in industry, agricultural, national defence,
The fields such as biology, medicine.China's boron is resourceful, has verified boron reserves and has accounted for the world the 4th, has been mainly distributed on Liaoning, Qinghai, west
The areas such as hiding.Wherein Liaoning Area is existed in the form of magnesium borate ore, and by the exploitation of decades, reserves sharply decline；It is western
Boron resource be largely in the form of liquid mine store, be primarily present in salt lake bittern (the big of Han Jing salt after mentioning lithium
The new process of boron extraction studies [D] Postgraduate School, Chinese Academy of Sciences (Qinghai Salt Lake research institute) in lake bittern water, and 2007.), mesh
Preceding not yet effective development and utilization, therefore further developmental research is also needed for the method for extracting boron in salt lake bittern.
At this stage, from salt lake bittern extract boron method mainly have: acidization, extraction, the precipitation method, fractionation crystallization,
(salt lake Zhang Jincai concentrated brine mentions part Experiment research [D] Postgraduate School, Chinese Academy of Sciences (Qinghai salt of boron to absorption method etc.
Lake research institute), 2005.).Absorption method is that boron is enriched with from brine using selective absorption of the adsorbent to boron, is acted on
Mechanism substantially has hydrogen bond action, electrostatic attraction, hydrophobic interaction and chelation, wherein most boron adsorbent is mainly benefit
With the chelation of functional group and boron, boron is high-efficient, and technique, equipment are simple, and adsorbent can be recycled with mentioning for absorption method
The advantages that (the Xie Yu base of function containing o-dihydroxy adsorbs the synthesis of resin and pedagogical to Hunan Study on adsorption properties [D] of boric acid
University, 2013.).
According to adsorbent type, inorganic adsorbent, organic adsorbent can be divided into.Inorganic adsorbent includes magnesia or hydrogen-oxygen
Change inorganic, metal oxides or the inorganic metal hydroxide such as magnesium, the right substance is larger by other ion interferences in brine, right
Boron is extracted to adversely affect；Organic adsorbent has meglumine class special efficacy to adsorb resin, composite adsorption resin, and there are also some other
Polyhydroxy organic adsorbent mainly extracts boron to the chelation of boron using the hydroxy functional group on molecule or strand,
Key is to improve the utilization rate of functional group, standby to have selectivity good, large amount of adsorption, durable functional resin.
Polyurethane is a kind of polymer for containing multiple-NCO recurring groups, has higher mechanical strength, oxidation surely
The excellent properties such as qualitative, flexibility, resilience, oil resistivity, solvent resistance, water resistance and fire resistance, be widely used in glue,
The fields such as medical treatment, biomaterial (Zhang Zhen river, Zhu Lili, the preparation of Jin Juan polyurethane foam adsorbent and its metal ion richness
Application [J] material Leader in terms of collection/separation, 2017,31 (05): 34-39.).Super branched polyurethane is a kind of with special
The polyurethane resin of shape possesses highly branched and three-dimensional globular structure, difficult compared to linear, branching and cross-linked polyurethane
With crystallization, without winding chain, possess more functional end-groups, be readily synthesized, therefore in recent years, super branched polyurethane is answered extensively
For various industries.But the polyurethane material currently used for boron absorption also there have been no scholar's research, if its excellent performance can be combined
Developmental research is carried out, application prospect will be boundless.
