Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a fireproof coating and a preparation method thereof. Background technique [0002] Fire retardant coating is to brush the paint on the surface of those flammable materials, which can improve the fire resistance of the material, slow down the speed of flame spread, or prevent burning within a certain period of time. This type of coating is called fire retardant coating, or flame retardant coating. At present, the fireproof performance of fireproof coatings on the market is not high, resulting in reduced service life, and it is difficult to meet the needs of the market. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a fireproof coating and a preparation method thereof. The invention has excellent fireproof performance. [0004] A kind of fireproof coating proposed by the present inventi...
