Abstract

The invention discloses an anion anti-oxidation coating for an automotive leaf spring and a preparation method of the anion anti-oxidation coating, and belongs to the field of anti-oxidation coatings. The epoxy resin is improved by adopting polyurethane resin, so that the anticorrosion ability and the hydrolysis resistance are improved, and the oxidation resistance of the product is excellent. Butyl hydroxy polyurethane adopted by the invention is synthesized by olefine dihydric alcohol and toluene diisocynate; and relative to polyether or polyester polyurethane, butyl hydroxy polyurethane has relatively good stability, hydrolysis resistance and corrosion resistance due to stable main chain structure. The tourmaline contained in the coating can automatically release anions, has the environment-friendly function, can be used or effectively removing harmful pollutants in air, and is beneficial to air purification and human health; and the anion anti-oxidation coating is simple in preparation process, convenient to operate and low in cost.

Description

technical field [0001] The invention relates to a preparation method of an anti-oxidation coating, in particular to an anion anti-oxidation coating used for automobile spring steel plates and a preparation method thereof. Background technique [0002] Automotive spring steel plate, also known as leaf spring, is the most widely used elastic element in automobile suspension. It is an elastic beam of approximately equal strength composed of several alloy spring sheets of equal width but unequal length. Spring steel plates are primarily used to transmit vertical forces and to moderate shocks and vibrations caused by uneven road surfaces. Its advantages are simple structure, reliable operation, low cost and convenient maintenance. It is both the elastic element of the suspension and the guiding device of the suspension. One end of it is hinged with the frame, which can transmit various forces and moments, and determine the beating track of the wheel. However, when the spring s...
