Powder coating metal overlay decoration plate and manufacturing method thereof

Abstract

The invention discloses a powder coating metal overlay decoration plate and a manufacturing method thereof. The powder coating metal overlay decoration plate comprises an artificial plate or natural plate base material, wherein a metal face plate covers at least one surface of the artificial plate or the natural plate base material through an adhesive; a powder coating layer is sprayed on the surface of the metal face plate. The manufacturing method of the powder coating metal overlay decoration plate comprises the following steps: 1. blanking the artificial plate or the natural plate base material and the metal face plate according to dimensional requirements respectively; 2. coating the surface of the metal face plate with powder coating, and heating and solidifying; 3. attaching the metal face plate coated with the powder coating to the artificial plate or the natural plate base material through the adhesive. The characteristics of environmental protection and energy conservation of the powder coating and the mechanical properties of high thermal stability and smoothness of a metal plate material are fully utilized, and the powder coating and the metal plate material are combined, so that the problem that the artificial plate or the natural plate base material is unlikely to be coated with the powder coating is well solved.

Description

technical field [0001] The invention belongs to a decorative board, in particular to a powder coating metal veneer decorative board and a manufacturing method thereof. Background technique [0002] Decorative board is the base material of various cabinets, countertops, floors and decorations. At present, decorative panels such as melamine panels are widely used in the market, but they have serious problems of releasing harmful substances, are not fire-resistant and flame-retardant, and have poor surface mechanical strength. , The color is single, it cannot be gongs and flowers, it can only be straight edged, the process is complicated, it is brittle, and it is easy to break when it is bent. Powder coating is a new type of solvent-free 100% solid powder coating, which has the characteristics of solvent-free, pollution-free, recyclable, environmental protection, energy and resource saving, labor intensity reduction and high mechanical strength of coating film. Metal material...

AI Technical Summary

Problems solved by technology

However, the use of powder coatings on heat-labile wood-based panels is still in the research and development stage, and mature technologies and products have not been formed. Even coking, burning, and the use of powder coatings must be cured at a temperature range of 180 to 240 ° C; second, the moisture content in wood is relatively high, even if the low-temperature curing powder coatings that are being discussed and researched are available, due to heating and curing During the process, the water in the wood-based panel is continuously evaporated and overflowed by heat, and a large number of pores will appear on the powder coating, which will affect the appearance decoration effect. Even if the above two defects are solved and overcome through technology, the inherent physical roughness of the wood-based panel surface restricts The leveling effect of the powder coating after curing is difficult to meet the ideal aesthetic requirements
