Problems solved by technology

The traditional preparation method of strongly acidic cation exchange resin, because the white ball is not mixed with the monomer, leads to the cracking of the white ball, which affects the subsequent processing. At the same time, the treatment of the subsequent diluent ensures the reduction of environmental pollution is also the current problem

Embodiment Construction

[0017] refer to figure 1 An example of a method for preparing an extra-strongly acidic cation exchange resin of the present invention will be further described.

[0018] For ease of description, if spatially relative terms such as "upper", "lower", "left", and "right" are used in the embodiments, they are used to describe the relative relationship between one element or feature shown in the figure and another element or feature Relationship. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the sp...

Abstract

The invention discloses a preparation method of super-strong acid cation exchange resin, and aims to provide the preparation method of the super-strong acid cation exchange resin with good preparationeffect, simple structure and good neutralization reaction effect, and the key points of the technical scheme comprise that under the condition of ensuring continuous attention to white balls, the stirring speed is adjusted, and the phenomenon of the white ball splitting is avoided; when the white balls are prepared, after monomers are added, the starting rotating speed is slow, after the monomersare completely dispersed, the oil droplets are sucked out by a material taking pipe and the sizes of the oil droplets are observed; if the oil droplets are too large, slow acceleration is carried outuntil the requirements are met, and then heating reaction is carried out; on the contrary, if the oil droplets are too small, the quantity of the monomers needs to be increased, and the size of the oil droplets is ensured to be in the balanced state; the stable stirring speed needs to be maintained in the white ball preparation process so as to improve the stability and ensure the preparation effect; the method is suitable for the technical field of ion exchange resin preparation.

Description

technical field [0001] The invention relates to the technical field of ion-exchange resin preparation, more specifically, it relates to a method for preparing an extra-strongly acidic cation-exchange resin. Background technique [0002] At present, the preparation method of extra-strongly acidic cation-exchange resin on the market, the strong-acidic cation-exchange resin, is to use oil-soluble unsaturated sulfonate and styrene monomer as raw materials, with divinylbenzene as cross-linking agent, through free White spherical particles with a particle size range of 0.5-1.2mm are prepared by suspension polymerization initiated by radicals, the content of sulfonic acid groups is 30.3-32.4%, and the ion exchange capacity is 3.7-5.2meq / g. The traditional preparation method of strongly acidic cation exchange resin, because the white ball is not mixed with the monomer, leads to the cracking of the white ball, which affects the subsequent processing. At the same time, the treatment o...
