Example Embodiment

[0079] Example 1

[0080] For a synthetic method of reticulated cross-linked zinc polyacrylate, the synthesis is carried out according to the following four steps and corresponding conditions.

[0081] The first step is to prepare materials:

[0082] Choose the water phase synthesis method and prepare the five raw materials required for the water phase synthesis: zinc oxide, acrylic acid, NN′-methylene bisacrylamide, potassium persulfate and distilled water. In addition to distilled water, the other four The purity of each chemical is chemically pure.

[0083] The second step, identification and initial ingredients:

[0084] Zinc oxide powder in barrels is packed in ziplock bags, marking it as component A. Acrylic acid was formulated into a 50wt.% aqueous acrylic acid solution, which was identified as component B. Potassium persulfate was formulated into a 2wt.% aqueous solution, which was identified as component D. N N'-methylenebisacrylamide was formulated into a 2wt.% aqueous sol...

Abstract

The invention relates to a synthesizing method of cross-linked zinc polyacrylic acid and a representative using method of the cross-linked zinc polyacrylic acid, in particular to a synthesizing method of reticular cross-linked zinc polyacrylic acid and a using method of the cross-linked zinc polyacrylic acid in batteries. According to the synthesizing method, acrylic acid serves as a monomer, zinc oxide serves as a neutralizing agent, and synthesizing of the reticular cross-linked zinc polyacrylic acid is achieved in an aqueous system under the action of a cross-linking agent and a one-component initiator. A synthesized product is used for replacing an anode active material of a nickel-zinc secondary battery, in this way, the representative using method of the cross-linked zinc polyacrylic acid is achieved, and the practicability of the cross-linked zinc polyacrylic acid in improving low-temperature power performance and self-discharge control of a nickel-zinc rechargeable battery and the like is achieved. A reference is provided for application of the cross-linked zinc polyacrylic acid in silver-zinc batteries, MnO2-zinc batteries, Edison batteries and the like. The polymerization method has the advantages of being short in process, easy to operate, high in safety, low in product cost and the like, and a basis is laid for application of the synthesized product in the fields such as non-toxic preservation of potatoes, efficient utilization of feminine sanitary towels, green mildew preventives for leather, micro-element fertilizers and accelerants.

Description

technical field [0001] The invention relates to the field of cross-linked polyacrylate polymer synthesis; in particular, it relates to a method for synthesizing network cross-linked zinc polyacrylate and the usage of the compound in batteries. Background technique [0002] Terms such as zinc acrylate polymer, zinc acrylate resin, zinc polyacrylate, and cross-linked zinc polyacrylate are ambiguous in general scientific journal titles or industrial titles. One of the reasons is the complexity of polymers, and sometimes these superordinate concepts belonging to polymers have to be used. [0003] In industry or commodity trading, macromolecules or macromolecules and polymers are used to be called "resin". The ambiguity of the title or product name adds an extra burden to researchers in searching and reading scientific and technological literature. Usually, in the retrieved title, they have to delve into the raw materials used in the text of the literature, the polymerization pr...
