Abstract

The invention discloses an epoxy polyester orange-figure powder coating and a preparation method thereof and belongs to the field of chemical engineering and solves the problem that a proper oil absorbency cannot be provided as a conventional epoxy polyester orange-figure powder coating uses single filler. The coating is prepared from the following raw materials in parts by weight: 20-22 parts ofepoxy resin, 29-30 parts of polyester resin, 6-7 parts of titanium dioxide, 9-11 parts of barium sulfate, 27-30 parts of calcium carbonate, 1-1.5 parts of an electric power increaser, 1-1.2 parts of adry powder flowing agent, 1-1.2 parts of a wetting dispersant, 0.5-0.8 part of benzoin, 0.1-0.2 part of a phenol accelerant, 0.3-0.5 parts of an antioxidant and 0.04-0.06 part of a pigment. The product design is free of any curing agent. Based on a way of matching filler with different oil absorbencies as a design concept, the raw materials are environment-friendly and non-toxic, and the coatingdoes not harm the physical health of constructors and is an environment-friendly product.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to an epoxy polyester orange pattern powder coating. Background technique [0002] In recent years, with the promulgation of a series of environmental protection policies and the tightening of environmental protection law enforcement supervision, coupled with the change of people's aesthetic concept of indoor products, epoxy polyester orange pattern powder coating has zero VOC emission, no organic solvent, powder The coating can achieve almost 100% utilization rate and the characteristics of high-efficiency spraying process, and is widely used in indoor filing cabinets, power distribution cabinets and other indoor environments. [0003] Epoxy polyester orange pattern powder coating is based on bisphenol A epoxy resin and carboxyl-terminated polyester resin as the main reaction film-forming resin, plus pigments, fillers and additives, mixed in a high-speed crushing mixer ...
