Description
Technical Field
The invention relates to the technical field of material repair, in particular to a repair method of an acrylate polymer material.
Background
The acrylate polymer is one kind of high molecular polymer with acrylate as monomer and has main chain similar to polyacrylic acid and side chain of carboxylic acid cation salt. Most of the acrylate polymers have the advantages of high modulus, high rigidity, good heat resistance and insulativity and the like, and are widely applied to the fields of electronics, machinery, constructional engineering and the like. In the field of constructional engineering, the water conservancy and hydropower science institute and the Yangtze river academy of sciences in China are sequentially in the middle and later stages of 80 s, and an acrylic acid salt chemical grouting material is developed on the basis of the work of the former, and has the functions and principles that acrylic acid salt is polymerized into an acrylic acid salt gel polymer which is insoluble in water under a certain initiator, the anti-seepage and plugging effects are realized, and the material is also applied to projects such as Yangtze river three gorges.
However, while acrylate polymer materials are used in a variety of fields, there is little research on simple and environmentally friendly material repair methods. Taking magnesium acrylate waterproof material used in the field of constructional engineering as an example, the polymer of the material is insoluble in water and has good adhesive force after being sprayed to form a film, but when the material is subjected to environments such as strong acid, strong alkali or high salt content, the polymer material is degraded to a certain extent, and the waterproof capability of the material is seriously affected.
