Problems solved by technology

However, currently commercially available HAA-type powder coatings often do not have flame-retardant properties, and the development of flame-retardant hydroxyalkylamide-type powder coatings has a very broad market prospect.
[0004] The invention patent with the application number 201610716227.5 announced a patented outdoor weather-resistant powder coating. The coating has good weather resistance due to the addition of graphene, but the coating has poor flame retardancy and is not suitable for flame-proof and flame-retardant In the field of material spraying, the invention patent with the application number of 201611027453.9 at the same time announced an outdoor foamable powder coating, which added flame retardant additives, and the flame retardant additives were tetrabromobisphenol A, tris(2) phosphate , 3-dichloropropane) ester or one of the two ladders of trioxide, the flame-retardant effect of the prepared coating is poor, and it cannot meet the flame-retardant requirements of the coating for flammable electrical appliances, automobiles, passenger cars, etc., and the invention patent does not have Published the preparation process of outdoor foamable powder coatings

Abstract

The invention discloses hydroxyalkylamide-cured outdoor type flame retardant powder coating which is prepared from the following components in parts by mass: 65 parts of outdoor polyester resin, 4 parts of a hydroxyalkylamide curing agent, 2 parts of a smooth degassing agent, 2 parts of a leveling agent, 5-10 parts of a compound flame retardant and 17-22 parts of pigments and fillers, wherein the compound flame retardant is prepared from the following raw materials in parts by weight: 5 parts of aluminum hydroxide, 5 parts of magnesium hydroxide, 16 parts of zinc borate, 32 parts of barium borate, 6 parts of antimony trioxide and 36 parts of diatom mud. The powder coating provided by the invention adopts the self-made compound flame retardant, so that the obtained coating has low thermal conductivity, can reduce the speed of heat transfer to a protected substrate, can also effectively isolate oxygen, increases heat absorption capacity, has excellent flame retardancy, and does not affect coating leveling, weather resistance, impact resistance and other properties.

Description

technical field [0001] The invention belongs to the technical field of powder coatings, in particular to a hydroxyalkylamide cured outdoor flame-retardant powder coating. Background technique [0002] As people's requirements for health and environmental protection are getting higher and higher, although the traditional carboxypolyester / TGIC system is uniform, stable, adjustable, has good heat resistance and weather resistance, and can basically meet user requirements, but its strong skin irritation Sexuality and potential carcinogenicity make it inevitable to withdraw from the market. HAA type (hydroxyalkylamide) compounds are recognized as low-toxic and environmentally friendly compounds. They have been widely used in the fields of daily chemicals, surfactants and coatings, especially in the field of powder coatings as curing agents for polyester coatings. They have strong reactivity. , suitable for low temperature curing conditions, good storage. [0003] High molecular...
