Abstract

The invention relates to a high-temperature-resistant high-airtightness composite material for repairing a heat distribution pipeline, and a preparation method and application of the high-temperature-resistant high-airtightness composite material. The composite material comprises 100 parts of ethylene propylene rubber, 5-10 parts of PIB, 3-5 parts of nanometer zinc oxide, 2-5 parts of polyethyleneglycol, 2-5 parts of a peroxide crosslinking agent, 1-2 parts of an assistant crosslinking agent, 0.2-3 parts of an anti-aging agent, 15-100 parts of carbon black N550, 15 parts of white carbon black, 5-15 parts of paraffin oil, 1-3.5 parts of resorcinol, 1-3 parts of a formaldehyde donor and 10-80 parts of flaky talcum powder. The composite material is prepared through mixing and open-milling; then the composite material is extruded to obtain a pipe; and the pipe is vulcanized at 150-180 DEG C to obtain a composite material pipe for repairing the heat distribution pipeline. The composite material disclosed by the invention is used for the pipe applied to heat distribution pipeline repairing, has good high temperature resistance, can be used for a long time at 150 DEG C, and is high in air tightness, good in mechanical property, heat resistance and aging resistance and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-temperature-resistant and high-air-tightness composite material for repairing thermal pipelines, a preparation method and application thereof. Background technique [0002] The pipes that transport steam and superheated water are called thermal pipes. Due to the high temperature and high pressure of the transported medium, the corrosion of the pipes is relatively serious. Traditional transmission pipelines are made of metal. Due to the long-term laying, damage and aging have occurred to varying degrees, which will not only affect the normal operation of the pipeline, but also pose a potential threat to public safety and social stability. It is particularly important to find hidden dangers and repair them in time to maintain the safety of the heat pipe network. [0003] At present, the main repair method of thermal pipeline repair is to use the method of passing ...
