The present invention relates to far infrared enamel glaze, and is especially one kind of enamel glaze sintered onto iron pipe. The glaze consists of fused block, silicon carbide, calcined sand and oxide with infrared radiation performance. The said materials are ground and mixed while adding water, and the mixture is painted onto iron pipe and heated at 800-1000 deg.c for 4-12 min to form enamel sintered firmly onto the surface of the iron pipe. The present invention has the advantages of easy sintering, high infrared radiation performance, less likely to fall and long service life.

The present invention relates to one kind of solid solution cordierite series ceramic powder with infrared radiation and bacteriostasis functions and its preparation process. The ceramic powder has the main components of Al2O3, SiO2, MgO and ZnO, which are prepared into white solid solution cordierite series ceramic powder through ceramic making process. The ceramic powder has normal whole waveband radiance of 0.87-0.90, 8-25 micron waveband radiance of 0.90-0.94, 8-14 micron waveband radiance of 0.88-0.94 and 14-25 micron waveband radiance of 0.91-0.94. The bacteriostasis function test shows that the ceramic powder has obvious inhibiting effect on urea sarcin and Staphylococcus aureus, with bacteriostasis rate reaching 84.1-100 %. The present invention has simple process, low cost and wide application range.

The invention discloses a sun-proof and heat-insulating coating for buildings and a preparation method thereof. The blend is obtained by mixing water-based acrylic resin, modified silica airgel, zinc phosphate, organic fluorine epoxy resin and silicone resin , put the blend into the mixing tank, stir evenly and then filter, and mix the boric acid microparticles and inorganic fillers into the SiO 2 In the sol precursor, it fills the defects in the nonlinear optical crystal, and then regulates the infrared radiation performance, and undertakes the function of enhancing the infrared radiation performance of the atmospheric window band. Adding a dispersant makes the molecular chain of the dispersant fully stretch in the aqueous solution. In SiO 2 A surface adsorption layer of a certain thickness is formed on the surface of the airgel particles, which produces a steric hindrance effect, thereby achieving the promotion of the development of high-grade green buildings and the improvement of SiO 2 The purpose of dispersion stability of airgel system.

The invention relates to an efficient heat dissipation coating and an application method thereof. The heat dissipation coating is prepared from, by mass, 5%-20% of superfine graphite, 1%-10% of infrared radiation powder, 20%-50% of a bonding agent, 30%-50% of a solvent and 0.1%-3% of a dispersing agent, wherein the proportion sum of all the components is 100%. A preparation method of the efficient heat dissipation coating comprises the steps that the weighted superfine graphite, infrared radiation powder, bonding agent, dispersing agent and solvent are mixed and then stirred to be uniform to obtain slurry; the slurry is uniformly applied to the surfaces of metal heat dissipation fins of electronic equipment through a spraying or immersing method, natural curing is conducted under the room temperature condition, and heat preservation is conducted for 2 h. The efficient heat dissipation coating has the heat conductivity coefficient approaching to that of graphite and can effectively decrease the surface temperature of the electronic equipment, improve the operating reliability of the electronic equipment and prolonging the service life of the electronic equipment; the full-wave band radiance is stable at 0.96 or above for a long term; when the heat dissipation fins of the electronic equipment are in a working state under the temperature of 80 DEG C to 100 DEG C, the surface temperature of the heat dissipation fins coated with the efficient heat dissipation coating is decreased by 8 DEG C-10 DEG C than that of the heat dissipation fins not coated with the efficient heat dissipation coating.
