Abstract

The invention discloses a nanometer high temperature resistant thermal insulation and prevention coating. SiO2 aerogel, modified potassium hexatitanate whisker, aluminum silicate fiber, ultra-fine cenosphere, nanometer TiO2 and nanometer Al2O3 are used as a thermal insulation filler. A vacuum thermal insulation layer is formed by nano porous structures of SiO2 aerogel and cenosphere. The aluminum silicate fiber is used as a reinforcing and toughening material. The infrared shading performance of potassium hexatitanate whisker, nanometer TiO2 and nanometer Al2O3 are used as a thermal radiation shielding layer. A silicon resin emulsion and an acrylic emulsion are compounded to be an adhesive. Therefore, the nanometer 600 DEG C temperature resistant thermal insulation and prevention coating is prepared with matching of a variety of functional additives. The nanometer high temperature resistant thermal insulation and prevention coating has the characteristics of scumbling, thermal insulation, waterproofing, anti-crack, anti-corrosion, high temperature resistance, weather-proofing, durability and the like and is applicable to the field of industrial high temperature resistant thermal insulation energy conservation.

Description

[0001] Field of invention [0002] The invention relates to the technical field of industrial high-temperature-resistant heat-insulating and energy-saving protective coatings, in particular to a nanometer high-temperature-resistant heat-insulating and heat-preserving coating. Background technique [0003] As we all know, in order to achieve the goals of ecological environmental protection, energy saving and emission reduction, effective heat insulation and anticorrosion measures must be taken for the surface of metal structures such as industrial heat transmission pipes and thermal equipment. In the prior art, traditional thermal insulation materials such as rock wool felt, inorganic thermal insulation mortar, polystyrene foam board, foamed polyurethane, etc. are widely used, but the use of these traditional thermal insulation materials must reach a certain thickness to have a relatively high performance. Good thermal insulation performance is time-consuming and labor-intensiv...
