Abstract

The invention belongs to the technical field of anti-flaming static electricity conducting organic silicon nano ceramic coating, and particularly relates to anti-flaming static electricity conducting organic silicon nano ceramic coating used for a coal-mine gas drainage pipeline and a preparation method of the coating. The coating comprises the following compositions: organic silicone resin, metal oxide, silicate fillers, carbon materials, nano ceramic powders and mixed solvents. The compositions are weighed according to proportion and mixed to be prepared into thick and sticky suspension fluid. According to the anti-flaming static electricity conducting organic silicon nano ceramic coating, two technologies, namely technology of the organic coating and the nano ceramic, are combined together, a paint film is converted into the inorganic type from the organic type at high temperatures, the inorganic coating with good flame retadance, static electricity conduction, temperature resistance and mechanical property is formed on the metal base layer so as to realize the comprehensive protection for a base body. The anti-flaming static electricity conducting organic silicon nano ceramic coating can be widely applied to corrosion resistance of oil pipelines, gas pipelines and chemical equipment.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a flame-retardant and static-conducting organosilicon nano-ceramic coating for coal mine gas drainage pipelines. Background technique [0002] Gas drainage during drilling and mining in coal production and mining operations plays an important role in mine gas control. At present, gas drainage pipes in coal mines are divided into non-metallic pipes and steel pipes. Non-metallic pipes mainly include glass steel pipes, polyvinyl chloride pipes (PVC), and polyethylene pipes (PE). FRP pipes have disadvantages such as high brittleness and poor impact resistance, while polyvinyl chloride and polyethylene pipes are not strong in pressure and have poor aging resistance. Patent CN 102146178 A discloses a flame-retardant and antistatic polyethylene used in coal mine gas drainage pipelines and its preparation method. It has good flame-retardant and antistatic properties, but there is no...
