Abstract

The invention discloses a food-grade powder coating as well as a preparation method and application thereof. The powder coating comprises modified phenolic epoxy resin, a phenolic curing agent and anaid. The powder coating has the properties of high corrosion resistance, strong impact resistance, low curing temperature, short curing time, good adhesion force, excellent coating appearance and thelike, can meet the food-grade health and safety requirements and is particularly suitable for the protection of water-related workpieces or containers such as water pipes, valves and water faucets andthe like for drinking water or groundwater.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a food-grade powder coating and a preparation method and application thereof. Background technique [0002] Powder coating has the characteristics of energy saving, no VOC emission, and safe use. In recent years, with the change of national environmental protection policy, "paint to powder" has become the general trend, and domestic powder coating technology has developed rapidly. The water pipes and valves that were originally painted with paint began to be gradually switched to powder coating. [0003] Powder coating products for water pipes and valves are mainly used in the protection of drinking water transmission and distribution equipment, such as the protective coating of the inner and outer walls of metal substrates for water-related products such as water pipes and valves. The coating thickness is usually 300~ 500μm, which is thicker than the coating thickness of general industr...
