Abstract

The invention discloses a thixotropic electrostatic spraying anti-rust oil composition as well as a preparation method and application thereof, and mainly solves the technical problem of poor thixotropic property of the thixotropic electrostatic spraying anti-rust oil composition in the prior art. According to the technical scheme, the invention provides a thixotropic electrostatic spraying anti-rust oil composition as well as a preparation method and application thereof, the thixotropic electrostatic spraying anti-rust oil composition comprises the following components in parts by weight: 70-90 parts of a base oil, 2-8 parts of a thixotropic agent, 5-15 parts of a barium-free anti-rust agent, 0.2-1 part of an antioxidant and 1-10 parts of an adjuvant, the thixotropic agent is selected from at least two of hydrogenated castor oil, fumed silica, polyamide, a polydiene compound, modified calcium sulfonate, aluminum distearate and organic bentonite, and the thixotropic agent at least comprises at least one of polyamide or a polydiene compound. The problem is well solved, and the thixotropic agent is suitable for being applied to electrostatic spraying anti-rust treatment of a cold-rolled steel sheet.

Description

technical field [0001] The invention relates to a thixotropic electrostatic spray antirust oil composition, a preparation method and an application thereof. Background technique [0002] Thixotropy is one of the important contents of the rheology research of dispersion system, which refers to a rheological phenomenon in which the viscosity or shear force of the system changes with time under agitation or other mechanical action. When the liquid is at a low shear rate, the viscosity is very high, and when the shear rate is increased, the viscosity decreases. The phenomenon that the viscosity rises again when the shear rate is lowered is called thixotropy. [0003] At present, the rapid development of the automobile manufacturing industry and the home appliance manufacturing industry not only requires the performance and quality of cold-rolled steel sheets and galvanized steel sheets to meet the corresponding standards, but also requires less anti-rust oil coated on the surfa...
