Abstract

The invention discloses a solvent type strippable plastic film antirust agent and a preparation method thereof. The solvent type strippable plastic film antirust agent comprises the following components in percentage by weight: 15.5-20.0% of polyvinyl chloride powder, 6.0-8.0% of a plasticizer, 1.0-3.0% of a corrosion inhibitor, 0.2-0.4% of organic alkali, 1.0-2.0% of an antioxidant and 66.8-76.3% of tetrahydrofuran. The antirust agent has the following advantages and effects: tetrahydrofuran is adopted as a solvent for dissolving the polyvinyl chloride powder, and the plasticizer promotes the film formation of polyvinyl chloride; when in use, a solvent type strippable plastic film forms a layer of plastic film which is attached to the surface of a metal product, and the plastic film is simply torn and stripped for removal; and moreover, by adding the organic alkali (benzotriazole) and the antioxidant (tert-butyl p-cresol), a synergistic effect can be realized, the antirust property of the solvent type strippable plastic film antirust agent is remarkably enhanced, and the effects of convenient removal and improvement of antirust property are realized.

Description

technical field [0001] The invention relates to the field of antirust technology, in particular to a solvent-type peelable plastic film antirust agent and a preparation method thereof. Background technique [0002] Corrosion of metal refers to the phenomenon that the metal is damaged by the electrochemical or chemical action of the surrounding medium. Rust inhibitors generally refer to substances that change the environment or electrode state on the surface of the metal so that it does not rust. It can penetrate into rust and corrosion to remove rust and corrosion. It has the functions of penetrating rust, resisting corrosion, Protection of metal and other properties. [0003] Solvent-based rust remover is a rust remover that dissolves various viscous substances and rust-removing substances in a solvent. The solvent generally includes tallow, vaseline, sodium petroleum sulfonate, etc. Solvent-based rust remover forms a viscous oil film after spraying on the surface of meta...
