Embodiment Construction
[0011] Stir the sodium silicate and water-based phenolic resin evenly at high temperature. The rotation speed of the mixer should reach more than 3500 / min to stir and mature. Continue to stir for more than 30 minutes. Cellulose, pH adjuster, coupling agent. Stir these raw materials, then add ceramic hollow microspheres and short ceramic fibers, and stir for more than 30 minutes until evenly stirred.

Abstract
The invention discloses a high-temperature-resistant heat insulation coating which has the temperature-resistant range of -80 DEG C to 1800 DEG C and the heat conduction coefficient of 0.03W/m.K only at 70 DEG C and has the characteristics of acid and alkali resistance, wear resistance, pressure resistance, watertightness, insulativity, fire prevention, mildew prevention, corrosion prevention, convenience in construction, long life and the like. The high-temperature-resistant heat insulation coating is a grey white slurry body and selects and uses silicate and water-based phenolic resin as film forming materials and nano ceramic hollow particles, silicon-aluminum fibers and various reflection materials as main powder materials. The high-temperature-resistant heat insulation coating can be used for effectively inhibiting and shielding infrared radiation heat and heat conduction, has the heat insulation efficiency of about 90%, and also can be used for inhibiting heat radiation and heat loss of high-temperature objects, keeping 70% of indoor heat, effectively insulating cold energy of low-temperature objects, inhibiting cold loss caused by environmental radiation heat and preventing condensed water from being generated.
Description
technical field [0001] High temperature resistant thermal insulation coating is a kind of functional coating with high temperature resistance, low thermal conductivity, water-based wear resistance and pressure resistance. Background technique [0002] Traditional heat insulation materials have a large construction thickness, and it is not easy to construct heat insulation on irregular objects, and their hardness is low and they cannot withstand pressure. Contents of the invention [0003] High temperature resistant heat insulation coating, the temperature resistance range is -80-1800 ℃, the thermal conductivity is only 0.03W / m.K, the coating also has acid and alkali resistance, wear resistance, pressure resistance, waterproof, insulation, fire prevention, mildew resistance, corrosion resistance, The characteristics of convenient construction and long service life are based on one suit. [0004] The high-temperature heat-resistant and heat-insulating coating is a gray-whit...
