Abstract

The invention provides a fireproof coating for the surface of a steel structure, wherein the fireproof coating comprises, by weight, 12-25 parts of a fluorosilicone emulsion, 20-35 parts of a siliconeacrylic emulsion, 2-8 parts of a flame retardant, 2-12 parts of a carbon forming agent, 15-25 parts of a foaming agent, 3-8 parts of white oil, 8-15 parts of a filler, 3-10 parts of an antirust agent, 0.5-1.5 parts of an auxiliary agent, 0.1-0.5 part of a bacteriostatic agent, 0.1-0.5 part of a pH regulator and 1-3 parts of refractory fibers. Compared with the traditional epoxy fireproof coating,the fireproof coating disclosed by the invention is more suitable for steel structure coating construction needing both fire prevention and corrosion prevention, has excellent adhesive force, cracking resistance and weather resistance, and does not crack or fall off in a high-low temperature alternating environment.

Description

technical field [0001] The invention relates to the technical field of fireproof coatings, in particular, the invention relates to a fireproof coating which can be used on the surface of steel structures, as well as its preparation method and application. Background technique [0002] At present, the intumescent fireproof coatings for hydrocarbon flames are generally epoxy fireproof coatings. This kind of coating has good mechanical properties, but it often has the defect that the formed fireproof coating is easy to crack and fall off, especially when the film thickness is relatively thick. This is especially true under the conditions of large ambient temperature differences. The main reason for this phenomenon is: the hardened coating is thick, the paint film is hard and brittle, when the internal stress of the paint film is greater than the cohesion, the paint film will crack; and when the internal stress of the paint film is greater than the adhesion, the paint film will ...
