Nano infrared heat-absorption composite material as well as preparation method and application thereof

Abstract

The invention belongs to the technical field of heat-absorption functional materials and in particular relates to a nano infrared heat-absorption composite material which is prepared from the following raw materials in parts by weight: 20-25 parts of instant sodium silicate, 27-32 parts of crystal silicon, 4-8 parts of nano aluminum oxide, 10-17 parts of a carbon fiber, 2-5 parts of nano titaniumoxide, 2-7 parts of nano zirconium carbide, 8-12 parts of nano yttrium and 15-28 parts of deionized water. The preparation method comprises the following steps: diluting the instant sodium silicate with deionized water according to the parts by weight, further adding the nano aluminum oxide, and conducting stirring so as to obtain a clear solution; further adding the carbon fiber, the nano titanium oxide, the crystal silicon, the nano zirconium carbide and the nano yttrium into the clear solution, and conducting uniform stirring, so as to obtain the nano infrared heat-absorption composite material. The preparation process provided by the invention is simple, the obtained material covers a metal surface to isolate the metal surface from external mediums, thus external high-temperature oxidation and corrosive substances can be obstructed, a metallic tube wall can be effectively protected, a remarkable heat absorption effect is achieved, infrared radiation can be resulted, and a very goodenergy conservation effect is achieved.

Description

technical field [0001] The invention relates to the technical field of heat-absorbing functional materials, in particular to a nanometer infrared heat-absorbing composite material and its preparation method and application. Background technique [0002] During the heavy oil throughput development process, ensuring the steam injection pressure, temperature, dryness and continuity of steam injection is directly related to the normal production of heavy oil. The steam injection boiler equipment is aging and the heat loss of the insulation layer is increasing. In order to ensure the steam Quality, improve the thermal efficiency of the boiler, prolong the service life of the boiler, and paint the far-infrared radiation coating on the surface of the water wall of the steam injection boiler. However, due to the cohesiveness and heat absorption efficiency of the coating are not up to the energy saving efficiency, the nano-infrared heat-absorbing composite material was invented by th...
