Embodiment example

[0073] As a preferred embodiment of the present invention, the raw materials of the ultra-low temperature powder coating include: polyester resin, epoxy resin and auxiliary agent, and the auxiliary agent includes one or more of a catalyst, an anti-sticking agent and a defoaming agent .

[0074] Wherein, the main material of the ultra-low temperature powder coating is the main polyester resin containing carboxyl group, the glass transition temperature is 40-60°C, the acid value is 10-75mgKOH / g, and the curing temperature is 90-130°C. Then use low-temperature curing (80-90 ℃) liquid or low-viscosity solid epoxy resin, and use high-efficiency catalyst to carry out low-temperature ring-opening reaction on epoxy resin, add a new type of defoamer for degassing and defoaming, and add a new type of anti-foaming agent. Adhesive to better solve sticking and clumping problems.

[0075] Specifically, the catalyst can be selected from 2-methylimidazole, 2-phenylimidazoline, tertiary amine...

Abstract

The invention discloses a coating method of an inorganic mineral plate. The coating method comprises the following steps of (1) selecting the inorganic mineral plate and carrying out dust removal and cleaning treatment, (2) sealing the inorganic mineral plates, (3) preheating the surface of the inorganic mineral plate to improve the surface conductivity of the inorganic mineral plate, (4) coating the surface of the inorganic mineral plate with ultra-low temperature powder paint for one or more times to form a powder coating, (5) curing the powder coating on the surface of the inorganic mineral plate, (6) decorating the inorganic mineral plate, and (7) carrying out quality inspection and packaging on the inorganic mineral plate to obtain a finished product. The invention further provides an inorganic mineral plate prepared by the coating method. With the adoption of the coating method, the method is simple, the process is controllable, various decorative effects can be achieved on the surface of the inorganic mineral plate by using the powder coating, and the problem that the powder coating and the inorganic mineral plate are difficult to match is solved.

Description

technical field [0001] The invention relates to the technical field of printed boards, in particular to an inorganic mineral board and a coating method thereof. Background technique [0002] Panels are flat, rectangular panels of building material in preset sizes, used in the construction industry as elements for walls, ceilings or floors. [0003] Boards include organic boards and inorganic boards. At present, the mainstream inorganic boards include calcium silicate fiberboard, gypsum fiberboard, calcium silicate board and magnesia board. Compared with organic boards, inorganic boards have the following outstanding features: 1. Class A non-combustible: traditional MDF with fireproof leather veneer can reach Class B flame retardant, while inorganic boards have the characteristics of Class A non-combustible, and the thickness of 10mm can be easily Reach the flame retardant limit of 3 hours. 2. Waterproof and moisture-proof: The material of the inorganic board is characteriz...
