Abstract
The invention discloses a method for preparing a cation exchange resin from macromolecule three-dimensional polymer. According to the method, concentrated sulfuric acid, fuming sulfuric acid, chlorosulfonic acid and sulfur trioxide are adopted as sulfonation reagents, the exchange property of a product can meet the requirements on the property of ionic exchange resin in the market, and the property of a part of products even exceeds that of the national one-class product standards. The method is simple in process, convenient to operate and capable of preparing the cation exchange resin of which the exchange rate is equivalent to that of 723 type cation exchange resin in the market.
Description
Technical field
The present invention relates to a kind of method being prepared into Zeo-karb with polymer three-dimensional polymer.
Background technology
Thermosetting epoxy resin and resol are polymer three-dimensional polymers, and their common features are molecular structures is crosslinked tridimensional network.Crosslinked tridimensional network has good mechanical property and thermotolerance, but the recycling that it does not melt, insoluble characteristic makes it after discarding has very high difficulty.If rationally recycle it, be not only conducive to environment protection, and the Sustainable development of society can also be advanced.
Summary of the invention
The object of the present invention is to provide a kind of method preparing Zeo-karb with polymer three-dimensional polymer.
For achieving the above object, the present invention adopts following technical scheme:
Be prepared into a method for Zeo-karb with polymer three-dimensional polymer, it is characterized in that the concrete steps of the method are:
A. by 10 parts of polymer three-dimensional polymers, 50-200 part sulphonating agent stirring reaction 1 ~ 6h at 50 ~ 90 DEG C of temperature; After reaction terminating, after question response system is cooled to room temperature, reactant after filtration, collects solid product;
B. wash step a-1 gained solid matter with deionized water to pH=7, filtering separation, then puts into oven dry by solid materials, i.e. obtained ion exchange resin.
Above-mentioned polymer three-dimensional polymer is: heat-reactive phenolic resin, bisphenol A type epoxy resin or bisphenol f type epoxy resin.
Above-mentioned sulphonating agent is oleum, chlorsulfonic acid or sulphur trioxide.
Waste and old printed circuit board adopts chemical sulfonation method to be prepared into ion exchange resin by the present invention, the switching performance of product can meet the performance requriements of commercial ion exchange resin, the performance of portioned product exceedes country-level product standard, proposition of this invention will promote the propagation and employment of waste and old printed circuit board New Process for Treatment, all will produce good positive effect to the comprehensive utilization of whole waste and old electric electrical equipment and environmental protection treatment.The property of the present invention is directed to is strong, intends dealing with problems clearly, has higher economy, environment and social synthesis's benefit.
The advantage of the inventive method is that technique is simple, easy to operate, can prepare exchange rate and be equivalent to commercially available 723 type Zeo-karbs.
