Abstract

The invention discloses a coating material and a preparation method thereof. The coating material is prepared by uniformly mixing and stirring the following raw materials in percentage by mass: 24-30%of zinc powder, 2-6% of rare earth modified aluminum bronze alloy powder, 6-10% of manganese nitrate, 20-25% of glycerin, 0.02-0.05% of phosphoric monoester, 1-5% of calcium dodecyl benzene sulfonate, 3-6% of rare earth modified ceramic material powder and the balance of water, wherein the average particle size of the zinc powder is 10-15 microns; the average particle size of the rare earth modified aluminum bronze alloy powder is 8-12 microns; and the particle size of the rare earth modified ceramic material powder is 5-10 microns. The coating material disclosed by the invention has excellent adhesive force and imperviousness, has excellent stability and practicality and can be widely applied to the fields of steel and the like. The preparation method disclosed by the invention is simple, low in production cost and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a coating material and a preparation method thereof. Background technique [0002] Chinese patent document CN107163694A discloses a preparation method of a waterproof dacromet coating, first dispersing aluminum powder, zinc powder, calcium silicate and bentonite in deionized water to obtain a mixed solution one; then thermoplastic styrene-butadiene rubber, acrylic resin , isooctyl oleate and ethylene-vinyl acetate copolymer are stirred and mixed to obtain a mixture; finally, the mixture is added to the mixed liquid 1, coupled with coupling agent, auxiliary agent and lubricant, and heated in a reflux container until boiling and reflux to a certain Time, down to room temperature, get waterproof dacromet coating. However, adhesion performance and waterproofness are not ideal. Contents of the invention [0003] The object of the present invention is to provide a coating material...
