Embodiment Construction

[0011] Each raw material was weighed according to the weight ratio in Table 1.

[0012] The weight proportion of table 1 embodiment 1~embodiment 3

[0013]

[0014] The above-mentioned solvent is selected from ethyl acetate, butyl acetate, and xylene, or a mixture of several in arbitrary proportions.

[0015] The above-mentioned epoxy resin is preferably a bisphenol A type epoxy resin.

[0016] The above-mentioned pigments and fillers can be selected from one of barium sulfate, talc powder, mica powder, aluminum oxide, and magnesium oxide or a mixture of several in any proportion.

[0017] The preparation method is as follows: dissolve the resin with a solvent, then add it, and stir evenly; send it to a three-roller grinder to grind until the fineness is qualified, then disperse it evenly in a mixer, filter and pack.

Abstract

The invention provides a corrosion-resistant fireproof coating, which belongs to the technical field of coatings. The corrosion-resistant fireproof coating comprises, by weight, 2 to 3 parts of ethylene-vinyl acetate copolymer emulsion, 1 to 2 parts of decabromodiphenyl ether, 5 to 10 parts of epoxy resin, 4 to 6 parts of chlorinated rubber, 5 to 10 parts of phenolic resin, 3 to 5 parts of perchlorethylene resin, 1 part of potassium titanate whisker, 1 to 2 parts of zinc-aluminum alloy powder, 1 part of melamine, 1 part of ammonium polyphosphate, 1 part of borax, 2 to 3 parts of glass powder, 5 to 8 parts of dibutyl benzoate, 2 to 7 parts of pentaerythritol, 6 to 12 parts of gypsum, 5 to 9 parts of acrylate resin and 10 to 20 parts of a solvent. The fireproof coating provided by the invention has excellent corrosion resistance and has fire resistance in accordance with national regulations.

Description

technical field [0001] The invention provides a corrosion-resistant fireproof coating, which belongs to the technical field of coatings. Background technique [0002] Fire retardant coatings are generally divided into two types: intumescent and non-intumescent. The non-intumescent type achieves the purpose of flame retardant and fire prevention through its own non-combustibility. To achieve a better fire prevention effect, it must be painted very thickly, and a large amount of flame retardant must be added. Hazardous substances, so the application is limited. The other type is intumescent fire retardant coating, which will expand when heated, thus preventing the transmission of flame to the substrate. However, the commonly used intumescent fireproof coatings have poor corrosion resistance and are prone to aging and cracking. After a long time of spraying, the fireproof effect will be affected.
