Problems solved by technology

[0003] Although the traditional solvent-based chassis anti-rust wax has good construction and good anti-corrosion performance, it is flammable and has high VOC emissions; water-soluble anti-rust wax uses water as a solvent, and no VOC is released during the construction process. The flash point is also greatly improved, but is easily affected by humidity and temperature in the environment

When the temperature drops to 60°C, add the thixotropic agent, stir for 10 minutes, add the drier and oily dye, and continue After stirring for 10 minutes, the automobile chassis antirust wax is prepared.

[0033] In the present embodiment: the mass fraction of each component in the antirust wax is: 36% of modified vegetable oil, 12% of raw wax, 26% of base oil, 12% of modified resin, 11.6% of thixotropic agent, 0.4% of drier, Oily stain 2%;

[0034] Modified vegetable oil: dehydrated castor oil 12.5%, tung oil 23.5%

[0035] Raw material wax: paraffin wax 7%, polyethylene wax 5%

[0036] Base oil: 10# mechanical oil 15%, industrial white oil 11%

[0037] Modified resin: Rosin modified phenolic resin 4%, asp...

Embodiment 3

[0042] Step 1: Add raw material wax and base oil to the reaction vessel, heat to 110°C, and stir evenly;

[0043] Step 2: Continue to add the modified resin to the reaction vessel to dissolve it completely. After stirring for 30 minutes, add the modified vegetable oil. When the temperature drops to 60°C, add the thixotropic agent, stir for 10 minutes, add the drier and oily dye, and continue After stirring for 10 minutes, the automobile chassis antirust wax is prepared.

[0044] In this embodiment: the mass fractions of each component in the antirust wax are: 40% of modified vegetable oil, 10% of raw wax, 20% of base oil, 12.8% of modified resin, 15% of thixotropic agent, 0.2% of drier, Oily stain 2%;

Abstract

The invention belongs to the technical field of anti-rust wax, and particularly relates to anti-rust wax for an automobile chassis and a preparation method thereof. The anti-rust wax comprises the following components in percentage by mass: 30-45% of modified vegetable oil, 10-15% of raw material wax, 20-40% of base oil, 10-20% of modified resin, 10-20% of thixotropic agent, 0.1-0.4% of drier and 1-2% of coloring agent. By adopting an oily system, the excellent hydrophobicity can ensure that the anti-rust wax is free from the influence of humidity in the environment, and meanwhile, the condition that a water-based product is easy to demulsify in a low-temperature environment is avoided. Compared with solvent-type chassis wax, with the solid content close to 100%, the anti-rust wax greatly reduces VOC emission, and the environmental protection property and safety are improved; the modified vegetable oil, the base oil and the modified resin are mixed to serve as a film-forming agent, the film-forming agent only has a slight vegetable oil smell, the metal surface is protected after film forming, and corrosion is effectively prevented; the thixotropic agent improves the thixotropy and the leveling property of wax, and the construction performance and the film forming uniformity are guaranteed; and the raw material wax improves the adhesive force and anti-rust performance of a wax film.

Description

technical field [0001] The invention relates to the technical field of antirust wax, in particular to an antirust wax for automobile chassis and a preparation method thereof. Background technique [0002] The car chassis is composed of four parts: transmission system, driving system, steering system and braking system. The function of the chassis is to support and install the automobile engine and its components and assemblies, form the overall shape of the automobile, and accept the power of the engine to make the automobile move and ensure normal driving. Corrosion damage is the most common and serious factor among the main factors affecting the service life of metal parts of automobile chassis. Coating anti-rust wax is an important way of anti-corrosion of automobile chassis, and it is also an important supplement for automobile electrophoresis anti-corrosion, and the anti-corrosion wax after construction will become a part of the body for a long time. [0003] Although...
