Abstract
The invention relates to a preparation method of sodium polyacrylate, which comprises the following steps: (1) Soaking polyacrylate in water solution containing sodium ions, and filtering to obtain solid sodium polyacrylate; the polyacrylate salt is a divalent cation salt or a cation salt with more than divalent cation. The preparation method can prepare the sodium acrylate polymer by using polyacrylate waste as a raw material.

Description
Technical Field
The invention relates to the technical field of polymer preparation and industrial or engineering waste recovery, in particular to a preparation method of sodium polyacrylate.
Background
The acrylate polymer (polyacrylate) is a high molecular polymer using acrylate as a monomer, and the main chain of the polymer is the same as polyacrylic acid, but the side chain of the polymer is carboxylic acid cation salt. Most acrylate polymers have the advantages of high modulus, high rigidity, good heat resistance and insulation and the like, and are widely applied to the fields of electronics, machinery, building engineering and the like. In the field of building engineering, the research institute of water conservancy and hydropower science and the institute of science of Yangtze river in the middle and late 80 years, acrylate chemical grouting materials are developed on the basis of the work of predecessors, the function and principle of the chemical grouting materials are that under a certain initiator, acrylate is polymerized into water-insoluble acrylate gel polymers, the anti-seepage and leak-stopping effects are realized, and the materials are also applied to projects such as the Sanxia of the Yangtze river.
However, while the acrylate polymer material is applied to various fields, a method for recycling waste of the material is rarely studied. Taking magnesium acrylate waterproof material used in the field of building engineering as an example, the material is difficult to avoid the phenomenon that the material polymerizes in a non-construction area due to improper storage or exceeding the shelf life or due to improper operation of workers in the construction process. Under these circumstances, magnesium polyacrylate waste which is difficult to dissolve in water is generated, and at present, no environment-friendly and efficient recovery method for polyacrylic acid waste such as magnesium polyacrylate and the like is provided, so that the waste can be recycled.
Therefore, there is a need for a method for recycling polyacrylate wastes in a simple and environmentally friendly manner.
