Embodiment 1

[0078] Embodiment 1 (non-expanding epoxy polyester hybrid type fireproof powder coating):

[0079] First take 5 kg of polyester resin and 5 kg of epoxy resin and heat them to the glass transition temperature, then add 5 kg of tris(dichloropropyl) phosphate flame retardant, keep warm and stir thoroughly, then cool into blocks and crush them, then With the remaining 30 kilograms of polyester resin and 30 kilograms of epoxy resin and 10 kilograms of brightener, 5 kilograms of leveling agent, 5 kilograms of light calcium carbonate and 5 kilograms of pigments, they are mixed and stirred, extruded, crushed after cooling and pressing, and processed. Sieve promptly obtain about 100 kilograms of non-expanded epoxy polyester hybrid type fireproof powder coatings of the present invention.

Embodiment 2

[0080] Embodiment 2 (expanded epoxy polyester mixed type fireproof powder coating):

[0081] First take 3 kg of polyester resin and 4 kg of epoxy resin and heat them to the glass transition temperature, then add 2 kg of dibromoneopentyl glycol flame retardant, 10 kg of pentaerythritol carbon forming agent, 6 kg of ammonium polyphosphate catalyst and 4 kg of more Ammonium polyphosphate foaming agent, heat preservation and fully stirred, cooled into blocks, crushed, and then mixed with the remaining 25 kg of polyester resin, 25 kg of epoxy resin, 9 kg of matting agent, 4 kg of wrinkle agent, 4 kg of superfine Barium sulfate and 4 kilograms of pigments are mixed and stirred, extruded, cooled and pressed into tablets, pulverized and sieved to obtain about 100 kilograms of the expanded epoxy polyester mixed type fireproof powder coating of the present invention.

Embodiment 3

[0082] Embodiment 3 (non-expandable epoxy type fireproof powder coating):

[0083] First take 10 kg of epoxy resin and heat it to the glass transition temperature, then add 8 kg of tetrachlorobisphenol A flame retardant, keep warm and stir well, then cool it into a block, crush it, and then mix it with the remaining 40 kg of epoxy resin, 20 1 kg of curing agent, 7 kg of brightener, 7 kg of hammering agent, 7 kg of light calcium carbonate and 1 kg of pigment are mixed and stirred, extruded, cooled and pressed into tablets, then pulverized and sieved to obtain about 100 kg of the non-expandable powder of the present invention. Epoxy type fireproof powder coating.

Abstract

The present invention relates to a decorative powder coating. It can be divided into two kinds of non-expansive fire-resisting powder coating and expansive fire-resisting powder coating. Its production process includes the following steps: heating proper quantity of polyester resin and / or epoxy resin to glass state temp., adding fire-resisting agent and / or carbon-forming agent, catalyst and foaming agent, stirring, cooling and pulverizing, mixing them with residual polyester resin and / or epoxy resin and other materials, stirring them, extruding, cooling, tabletting, pulverizing and sieving soas to obtain the invented products.

Description

technical field [0001] The invention relates to a decorative powder paint for exterior coating of products such as refrigerators, air conditioners, filing cabinets, bridge frames, bus ducts, and ventilation pipes. Background technique [0002] At present, the appearance of refrigerators, air conditioners, filing cabinets, bridges, bus ducts, ventilation ducts and other products are all coated with decorative powder coatings. There are three main types of existing powder coatings, one is epoxy polyester mixed powder coating, which is made by mixing, extruding, pulverizing and sieving epoxy resin, polyester resin and filler; Ester powder coating, which is made of polyester resin, curing agent and filler through the same process as above; the third is epoxy powder coating, which is made of epoxy resin, curing agent and filler through the same process as above become. However, the existing powder coatings do not have fireproof performance and will burn in case of fire, which m...
