Problems solved by technology

The Chinese patent CN 1380370A published on November 20, 2002 uses an additive flame retardant, which has the problem of aging attenuation, and the amount of catalyst used is small. The foaming agent uses ammonium polyphosphate, and the expansion and foaming ratio is low. The overall flame retardant effect not tall
The Chinese patent CN 101058694A published on October 24, 2007 uses a reactive flame retardant, which has a better flame retardant and fireproof effect, but the base material is all brominated epoxy resin, and the char-forming agent is dipentaerythritol. Not only the formula cost is higher , and during melt extrusion, the material mixing effect is not ideal, and the production cost is high
[0004] Existing fire-resistant powder coatings either have poor flame-retardant effects and aging resistance, or have high formulation and production costs, and are difficult to operate during production

Abstract

The invention discloses a finishing-typed fireproof powder coating, belonging to the technical field of the powder coating. The coating is prepared by normal production process by taking epoxy resin, brominated epoxy resin, polyester resin, a curing agent, a leveling agent, a degassifying agent, ammonium polyphosphate, melamine, pentaerythritol, pigment, antimony trioxide and a bulking agent as raw materials. The finishing-typed fireproof powder coating has the active effects that compared with the prior art, the coating has better flame-retardant and fireproof effect and better ageing attenuation resistance, lower formula cost and production processing cost and easier practical operation.

Description

technical field [0001] The invention relates to a decorative surface fireproof powder coating, which belongs to the technical field of powder coatings. Background technique [0002] Decorative fire retardant coatings can be divided into solvent type, water soluble type and powder type according to the material state, and can be divided into two types: intumescent type and non-expandable type according to the fire protection mechanism. [0003] Powder coatings have gradually attracted people's attention because of their energy saving, environmental protection, economy and high efficiency. There are more and more researches on fireproof powder coatings. The Chinese patent CN 1380370A published on November 20, 2002 uses an additive flame retardant, which has the problem of aging attenuation, and the amount of catalyst used is small. The foaming agent uses ammonium polyphosphate, and the expansion and foaming ratio is low. The overall flame retardant effect not tall. The Chine...
