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.
