Problems solved by technology

However, the coating of hot-dip aluminum plating has the problem of high energy consumption in the manufacturing process, which does not meet the needs of environmental protection
[0005] In addition, the hot-dip aluminum-coated steel plate needs a thicker coating to achieve the protective effect, so it takes a longer heat treatment time to achieve the annealing effect in the subsequent hot stamping process, which is not conducive to energy saving and reduction. Carbon demand, and a burden on production costs

Abstract

The present invention provides an organic-inorganic hybrid binder and a coating material containing the organic-inorganic hybrid binder, wherein the organic-inorganic hybrid binder is formed by mixingand reacting a liquid aluminum alkoxide, a chelating agent, a solvent and the like, and the coating material is formed by mixing the aforementioned organic-inorganic hybrid binder, metal materials, and dispersants. The coating material can be applied to a material surface by means of roller coating, spraying coating or immersion plating, and then baked at a high temperature, so that the coating material can be cured and fixed on the material surface to form a protective coating layer, protecting the material surface against high temperature thermal oxidation and high-salinity corrosion.

Description

technical field [0001] The invention relates to the field of coatings on material surfaces, in particular to an organic-inorganic hybrid binder for coatings on material surfaces, a coating comprising the organic-inorganic hybrid binder, and a method for forming the coating on the material surface. Background technique [0002] At present, due to the demand for environmental protection and the lightweight of automobiles, more and more attention is paid to it. The purpose of saving fuel can be achieved mainly through lightweight automobiles. Therefore, hot stamping steel materials are also receiving more and more attention and application; at present, the demand for hot stamping steel in automobiles is annual All have an upward trend. [0003] However, the original hot stamping steel needs to undergo high temperature heat treatment to have strength, and it needs to be hot stamped at high temperature, so as not to produce springback and cause the material forming specifications...
