Abstract

The invention relates to anti-static flame-retardant powder paint for a pipeline. The powder paint is characterized by being prepared from the following ingredients in percentage by mass: 30 to 60 percent of thermosetting resin, 4.5 to 30 percent of curing agents, 30 to 40 percent of fillers and 2 to 12 percent of auxiliary agents, wherein the sum of the percentage of all ingredients is 100 percent. By using the product, static electricity spray coating is used; the primary coating film thickness can reach 300 to 800 mu m; through primary baking curing, the performance requirement can be met;the coating work production efficiency is high; during the coating, powder paint which is not sprayed and coated can be recovered for use; the paint utilization rate reaches 98 percent or higher. A steel pipe after the powder paint coating has good anti-static flame-retardant performance; good adhesion force is realized between the coated coating and a substrate.

Description

technical field [0001] The invention relates to the technical field of thermosetting powder coatings, in particular to an antistatic and flame-resistant powder coating for pipelines, a manufacturing method thereof, and a high-voltage electrostatic coating method. Background technique [0002] As the main energy source for economic development, coal is known as black gold. The development and mining of coal provide a huge driving force for economic development and social progress. In early coal mining, there was no gas extraction device or ventilation device, and only natural ventilation was relied on. With the deepening of mining, natural ventilation can no longer meet the needs of safe production, and then forced ventilation devices appear. In order to avoid dust storms caused by excessive dust concentration during mining and transportation, water supply and drainage devices are used underground. [0003] In the past, metal and concrete pipes were generally used for underg...
