Abstract

The invention discloses a heat-insulating and wear-resistant pipe coating. The heat-insulating and wear-resistant pipe coating is prepared from the following raw materials in certain proportions: floating beads, nanometer hollow ceramic microbeads, waste electroceramic particles, expanded vermiculite, Guangxi white mud, activated aluminum oxide powder, silicon powder, carboxymethyl cellulose, epoxy resin, a T series curing agent and polypropylene explosion-proof fiber. The heat-insulating and wear-resistant pipe coating has relatively good wear resistance and washing resistance, and is applicable to lining coating of a factory hot air pipe; excellent heat insulation and volume stability reduce the heat loss of the hot air pipe, and good suspension is more conducive to coating during construction, so that the heat-insulating and wear-resistant pipe coating can be better attached to the surface of a construction body; meanwhile, the heat-insulating and wear-resistant pipe coating is convenient to construct and short in maintenance period, the heat insulation and the wear resistance thereof meet production needs, and the heat-insulating and wear-resistant pipe coating is high in comprehensive cost performance, prolongs the service life of the pipe and lowers the production cost; moreover, the heat-insulating and wear-resistant pipe coating has excellent fire-proof and heat-insulating effects, so that the heat-insulating and wear-resistant pipe coating can be also applied to outer-surface treatment of some firefighting pipes.

Description

technical field [0001] The invention relates to a thermal insulation refractory material, in particular to a thermal insulation and wear-resistant smear material for pipelines. Background technique [0002] Refractory material is a kind of special material serving the high-temperature industry. Due to the complex and diverse specific environments of the high-temperature industry, some insulation materials are designed to reduce temperature and heat loss, and some are to isolate temperature or open flames. Therefore, their The properties of materials should also be adjusted according to different parts of use and different emphases. For example, hot air pipes widely used in steel, coal coking, electric power and other industries need to be coated with a protective layer on the inner layer to make them have better wear resistance and heat preservation performance, which can not only reduce heat loss, but also effectively improve the pipe’s durability. service life.
