Problems solved by technology

At present, the pipelines used in coal mines are divided into water supply pipes, drainage pipes, positive pressure air pipes, spray pipes, and gas drainage pipes according to their purposes. When there is an abnormality in the pipeline, when it is necessary to open and close the pipeline, it is impossible to quickly identify the medium transported in each pipeline and its specific use, which will affect the efficiency of abnormal handling. In order to identify the type of medium transported in the pipeline, the mine usually adopts the following methods: 1 .Paste the identification plate, but the identification plate is easy to fall off and the recognit

Abstract

The invention relates to a fused epoxy powder material, a steel pipe and a preparation method and application thereof. The material is prepared from the following raw materials in parts by weight: 40to 60 parts of epoxy resin, 8 to 12 parts of phenolic curing agent, 20 to 30 parts of antistatic flame-retardant master batch, 2.6-12.5 parts of additive and 10 to 40 parts of nano filler; the antistatic flame-retardant master batch comprises the following raw materials in parts by weight: 10-20 parts of carbon nanofibers, 10-20 parts of conductive mica, 5-30 parts of conductive titanium dioxide,10-20 parts of a flame retardant, 0.5-1 part of a powder coupling agent and 40-60 parts of epoxy resin. The coating is prepared on the steel pipe and has excellent antistatic and flame-retardant properties. Various pigments can be replaced in the additive so that steel pipes with different colors can be manufactured, and recognition is facilitated.

Description

technical field [0001] The invention belongs to the technical field of pipeline anticorrosion, and in particular relates to a fusion-bonded epoxy powder material, a coated steel pipe and a preparation method and application thereof.
