Abstract

The invention relates to the technical field of coatings, in particular to a two-component superfine intumescent fireproof coating which comprises liquid A and powder B. The liquid A comprises 180 parts of water, 150 parts of Synthomer emulsion, 2.5 parts of mineral oil defoaming agent, 3 parts of organic silicon dispersing agent, 1.5 parts of wetting agent, 3 parts of flatting agent, 1 part of sterilizing agent, 1 part of mildew preventive, 1.5 parts of film-forming agent and 1.5 parts of thickening agent. The powder B is prepared from 220 parts of ammonium polyphosphate, 105 parts of melamine, 105 parts of pentaerythritol, 100 parts of Baili titanium dioxide, 75 parts of wollastonite powder, 25 parts of talcum powder and 25 parts of calcined kaolin. The invention further provides a preparation method of the two-component superfine intumescent fireproof coating. The fireproof coating has the characteristic that the fireproof coating can be stored for a long time.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a two-component superfine expansion type fireproof coating. Background technique [0002] With the rapid development of my country's economic construction, steel structure buildings are increasing day by day. Steel structures without fire protection treatment will lose strength and deform and collapse within 15 minutes of being exposed to fire. Ultra-thin steel structure fireproof coating has superior fireproof performance, heat insulation, acid and alkali resistance, thin coating, less dosage, low cost, lightens the load of steel structure, and has good decorative effect. It is suitable for heavy steel structures such as industrial plants, stations, airports, gymnasiums, TV towers, metallurgy, electric equipment and high-rise buildings. However, with the rise of water-based coatings, the fatal flaws of water-based coatings have gradually surfaced, which is now on the market. T...
