Abstract

The invention discloses a ring production line for preparing a low-temperature curing heavy-duty anticorrosion epoxy powder coating material. The ring production line comprises a first crushing device, a stirring device, a high-temperature extrusion device, a second crushing device, a screening device and a packaging device, wherein the first crushing device, the stirring device, the high-temperature extrusion device, the second crushing device, the screening device and the packaging device are sequentially connected through a transmission device to form a ring shape, the packaging device is connected to the first crushing device through a conveying pipe, the first crushing device, the second crushing device and the screening device are arranged in a closed room capable of being opened, the packaging device is arranged on the outer portion of the closed room, and the first crushing, the stirring device, the high-temperature extrusion device, the second crushing device, the screening device and the packaging device are connected to a control device. According to the present invention, with the ring production line, various processing devices of the epoxy powder are arranged into thering structure, and the devices producing the high powder and the high dust are separated into the closed room to perform the processing, such that the automation degree and the production efficiencyof the coating material production are improved, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of equipment for preparing low-temperature curing heavy-duty epoxy powder coatings, in particular to an annular production line for preparing low-temperature curing heavy-duty epoxy powder coatings. Background technique [0002] Epoxy powder coating, due to the high curing temperature of powder resin (180-220°C) and long curing time (10-30min), it can only be applied to heat-resistant substrates such as metals, and it is relatively energy-consuming and time-consuming; And because there is a certain overlap between the melt leveling and the initial stage of solidification, if the control is not good, the coating will have defects in flatness, such as shrinkage cavities, orange peel and other problems. For this reason, people have focused on developing UV-curable powder coatings and low-temperature curing powder coatings for heat-sensitive substrates. Generally speaking, the melting temperature of powder coat...
