The present application relates to the technical field of metal material chemical cleaning, and discloses an environment-friendly cleaning agent for degumming of a metal surface, comprising: tert-butyl hydrogen peroxide, diethylene glycol monobutyl ether, polyoxyethylene polyoxypropylene copolymer with a multi-branched structure, and deionized water, wherein the diethylene glycol monobutyl ether forms an associated structure with the tert-butyl hydrogen peroxide through hydrogen bonds; after the cleaning agent penetrates into the gap between the oxide film and the gum layer on the metal surface, the Lewis acid center of the oxide film competitively cuts the hydrogen bonds, induces in-situ decomposition of the tert-butyl hydrogen peroxide to release oxygen, and the interface pressure generated by the oxygen converts chemical energy into normal mechanical work, realizes whole peeling of the gum layer from the interface root, suppresses diffusion loss of the solvent in the gum layer body phase, and shortens the cleaning period without damaging the metal matrix.

This invention discloses a method for preparing a tear-resistant elastic gel, comprising the following steps: adding monomer molecules, a crosslinking agent, and a nano-confined material to a solvent, and performing a polymerization reaction under ultraviolet light irradiation in the presence of a photoinitiator to obtain the tear-resistant elastic gel. This invention utilizes the polymerization of monomer molecules and crosslinking agents initiated by a photoinitiator within the confined space of the nano-confined material. The strong hydrogen bonding between interpenetrating polymer segments effectively immobilizes polymer chains that may slide under load, preventing energy dissipation. Simultaneously, the rigid nano-confined material prevents stress concentration at crack tips in the host material and significantly reduces the crack propagation sensitivity of the prepared gel, thereby improving the strength, strain, crack propagation resistance, and elasticity under ultimate deformation of the gel material, thus obtaining a tear-resistant elastic gel.
