Abstract

The invention relates to the technical field of the powder coating, and in particular relates to a multi-system infrared curable powder coating for MDF. The multi-system infrared curable powder coating for MDF is prepared from the following raw materials in parts by weight: 200-500 parts of low-temperature high-acid polyester resin, 120-340 parts of bisphenol A type epoxy resin, 4-16 parts of hydroxyalkylamide, 12-80 parts of epoxy acrylic resin, 8-60 parts of epoxy modified phenolic resin, 0.5-8 parts of dimethyl imidazole accelerant, 2-10 parts of quaternary ammonium salt accelerant, 0-6 parts of acrylate flatting agent, 0-3 parts of sand ripples agent, 2-8 parts of polyamide wax micro-powder, 0-450 parts of barium sulfate, and 4-260 parts of pigment. Through the coordination of a plurality of curing systems, the defect of the single curing system is avoided. The powder coating disclosed by the invention is capable of well matching with the MDF powder infrared curing process, the environmental protection requirement is satisfied, and the film property is excellent.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to a multi-system infrared curing powder coating for MDF. Background technique [0002] Due to the advantages of environmental protection and superior performance, powder coatings have been rapidly popularized and applied in metal products in the past few decades. At the same time, with the continuous improvement of environmental protection requirements and film performance, people have begun to pay attention to the application of this new technology in heat-sensitive products such as MDF. Since the MDF substrate is very different from metal products, the surface density is poor and it is not resistant to high temperature. Therefore, during the leveling and curing process in the drying tunnel after the powder is adsorbed on the MDF surface, the control requirements for temperature and time parameters are very strict. In the past 30 years, various process technologies of MD...
