Abstract

The invention relates to the field of composite materials, and particularly provides novel composite hollow microspheres for high temperature resistant thermal insulation coating.The hollow microspheres are subjected to through acid etching and detonation hole making, a foundation is formed when titanium dioxide sol coats the hollow microspheres to improvedbonding force, the coated titanium dioxide sol is prevented from falling off during calcination, so that a titanium dioxide layer is evenly distributed on the surface of the hollow microspheres, and excellent heat reflection performance of the titanium dioxide and the ultra-low thermal conductivity of the hollow microspheres are fully utilized to realize good thermal insulation of the coating. The novel composite hollow microspheres forhigh temperature resistant thermal insulation coating is simple in operation, quick in reaction, high in production efficiency, and suitable for mass production, and the actual needs can be met.

Description

technical field

[0001] The invention belongs to the technical field of coatings, and mainly relates to a preparation method and application of hollow microspheres for high-temperature-resistant heat-insulating coatings. Background technique

[0002] 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 It has good thermal insulation performance, but it is time-consuming and labor-intensive in construction. The construction quality determines its poor waterproof performance. For outdoors, there is also sunlight exposure that is prone to cracking and water seepage of the insulation layer, which directly affects the anti-corrosion performance of the metal surface. However, the use of organic polymer foam material as the insulation layer has poor flame re...
