PIPELINE PROTECTIVE COATING AND METHOD OF APPLYING SUCH PROTECTIVE COATING ONTO PIPES

摘要

This invention concerns a coating material which can be used to rehabilitate the inside of pipelines, especially long-distance energy pipelines. Moreover, the invention concerns a coating produced out of the coating material and a process for its production. The curable coating material consists of a mineral component of at least 50 % by weight and at most 97 % by weight water and of a latex component of at least 3 % by weight and at most 50 %. A special composition of the curable coating material contains cement as the mineral component and natural latex as the latex component. An especially advantageous variant contains an admixture of fillers and/or of components which improve flow properties or strengthen or stabilize the curable coating material. Coating, especially of pipelines, is characterized by the fact that the coating consists of coating material as per the invention of a layer thickness of 1 to 30 mm. The coating can be used for long-distance energy lines which are operated under pressure. A special embodiment of the coating consists of a second coating layer which is made of the same components.
