Abstract

The invention discloses thermosetting weather-resistant low-temperature curing powder, which belongs to the technical field of new materials. 0.3%-0.6% of accelerator, 15%-25% of filler, 3%-15% of pigment, 0.5%-2% of auxiliary agent after mixing, the invention has the beneficial effect of curing the coating film The required baking conditions are only 140-150 ℃, 20min, the curing temperature is lower, the curing time can be shortened by 2 to 3 times compared with ordinary products, the mechanical properties are not affected, and it has good weather resistance, which can meet the needs of production and life. , can be used in wood processing, engineering plastics and some metal alloy materials and other fields, expanding the application field of traditional powder.

Description

[technical field] [0001] The invention relates to a cured powder, in particular to a thermosetting weather-resistant low-temperature cured powder. [Background technique] [0002] Powder coatings are increasingly popular because they rarely release volatile harmful gases to the environment during recoating and curing, and will not cause air pollution. The application of plastic, wood and some metal alloy materials is limited, and because of its relatively high curing temperature, it is not conducive to energy saving, and also affects production efficiency and other issues. [0003] At present, the surface of fire doors on the market is generally sprayed with outdoor powder. Since the fireproof cotton inside the fireproof door is glued to the door panel, the baking temperature of the glue should not exceed 160°C, otherwise the glue will melt and the fireproof cotton will fall off. The low-temperature curing powder is epoxy powder, and its curing conditions are mostly as follo...
