preparation example Construction

[0012] The invention provides a kind of preparation method of epoxy type fireproof powder coating, and this preparation method comprises:

[0013] 1) Heating the epoxy resin, then adding antimony oxide, sucrose, trisodium phosphate, and melamine for mixing, cooling, and crushing to obtain coarse material;

[0014] 2) The coarse material, epoxy resin, curing agent, micron barium sulfate, ammonium polyphosphate, aluminum silicate fiber, and sepiolite are heated, cooled, formed, and pulverized to obtain epoxy fireproof powder coating.

[0015] In step 1) of the present invention, the amount of each material can be selected within a wide range, but in order to further improve the fire resistance of the prepared powder coating, preferably, in step 1), epoxy resin, antimony oxide, The weight ratio of sucrose, trisodium phosphate and melamine is 10:1-1.5:2-3:2-3:1-2.

[0016] In step 1) of the present invention, the heating conditions can be selected within a wide range, but in orde...

Embodiment 1

[0025] 1) Heat the epoxy resin (heating temperature is 255°C, heating time is 1.5h), then add antimony oxide, sucrose, trisodium phosphate, melamine (weight of epoxy resin, antimony oxide, sucrose, trisodium phosphate, melamine The ratio is 10:.3:2.5:2.5:1.5) for mixing, cooling, and crushing to obtain coarse material (average particle size is 0.4mm);

[0026] 2) Combine coarse material, epoxy resin, curing agent (maleic anhydride), micron barium sulfate, polyphosphate amine, aluminum silicate fiber, sepiolite amine according to 10:38:13:4:6:5: Heat treatment at a weight ratio of 1 (under stirring conditions, the heating temperature is 255°C, and the heating time is 50 minutes), cooling and molding, and crushing to obtain epoxy-type fireproof powder coating A1 (the average particle size of the particles is 0.2mm) .

Embodiment 2

[0028] 1) Heat the epoxy resin (heating temperature is 250°C, heating time is 1h), then add antimony oxide, sucrose, trisodium phosphate, melamine (weight ratio of epoxy resin, antimony oxide, sucrose, trisodium phosphate, melamine (10:1:2:2:1) for mixing, cooling, and crushing to obtain coarse material (average particle size is 0.2mm);

[0029] 2) The coarse material, epoxy resin, curing agent (phthalic anhydride), micron barium sulfate, polyphosphate amine, aluminum silicate fiber, sepiolite amine according to 10:35:10:3:4:4: Heat treatment at a weight ratio of 0.8 (under stirring conditions, the heating temperature is 250°C, and the heating time is 40min), cooling and molding, and pulverization to obtain epoxy fireproof powder coating A1 (the average particle size of the particles is 0.1mm) .

Abstract

The invention provides epoxy-type fireproof powder coating and a preparation method thereof. The preparation method comprises the steps of 1) heating epoxy resin, and then adding, mixing, cooling andcrushing antimony oxide, sucrose, trisodium phosphate and melamine to obtain a crude material; 2) conducting heating treatment, cooling forming and crushing on the crude material, epoxy resin, a curing agent, micron barium sulfate, ammonium polyphosphate, aluminum silicate fibers and sepiolite to obtain the epoxy-type fireproof powder coating. The epoxy-type fireproof powder coating has excellentfireproof performance.

Description

technical field [0001] The invention relates to a powder coating, in particular to an epoxy fireproof powder coating and a preparation method thereof. Background technique [0002] Powder coating refers to a new type of solvent-free 100% solid powder coating; it has the characteristics of solvent-free, pollution-free, recyclable, environmental protection, energy and resource saving, labor intensity reduction and high mechanical strength of the coating film. Coatings are prepared by mixing special resins, pigments and fillers, curing agents and other additives in a certain proportion, and then through hot extrusion, crushing and sieving. Powder coating can be sprayed by electrostatic spraying, friction spraying (thermosetting method) or fluidized bed dipping (thermoplastic method), and then heated and baked to melt and solidify to form a flat and bright permanent coating film to achieve the purpose of decoration and anti-corrosion . [0003] Although the existing powder c...
