Problems solved by technology

[0004] 1. Some flame-retardant substances are added, which are difficult to adapt to the different layering requirements of the gloss of the powder coating. Although a certain flame-retardant effect is achieved, the decorative effect (especially the flatness) is poor and cannot meet the requirements of decorative functions. ;
[0005] 2. Some flame retardant substances are added, the flame retardant time and effect are poor, and there are shortcomings such as short ignition time, long burning time, low oxygen index, and short fire resistance time;
[0006] The bigger defect is that the added flame retardant substances have poor compatibility with the main film-forming substances in the original powder coatings, and cannot be well attached to the decorated objects, so they can no longer adapt to the increasing fire prevention and environmental protection in people's production and life. decoration requirements

Abstract

The invention discloses a ceiling powder paint which comprises the following raw materials in percentage by mass: 20-30% of end-carboxyl unsaturated polyester resin, 20-30% of epoxy resin, 28-33% of titanium dioxide, 3-5% of antimony trioxide, 10-15% of decabromodiphenyl ether, 2-4% of melamine, 1-2% of physical flatting agent, 0.8-1.2% of brightener and 0.8-1.2% of leveling agent. The invention also discloses a preparation method of the powder paint, which comprises the steps of premixing, extruding, milling and post-mixing. Compared with the existing ceiling powder paint, the powder paint of the invention has the advantages of high oxygen index and long fire resistance time, and enhances the fire resistance of the ceiling.

Description

technical field [0001] The invention relates to a powder coating, in particular to a powder coating mainly applied to ceilings and a preparation method thereof. Background technique [0002] Fire-resistant coatings can be divided into water-based, solvent-based and powder-based according to the form, and can be divided into intumescent and non-expandable according to the fire-proof mechanism. With the continuous enhancement of people's awareness of environmental protection, powder coatings with the characteristics of "economy, environmental protection, high efficiency and energy saving" have been developed rapidly and are increasingly valued. Intumescent fire retardant coatings mainly form a dense and stable carbon layer (foam layer) through expansion and carbonization (foaming) when the coating is burned, which effectively separates the flame from the substrate, thereby achieving the purpose of flame retardancy. Non-intumescent fire retardant coatings mainly achieve the pu...
