Abstract

The invention provides a heat-insulation ceramic coating material and a preparation method and application thereof. The heat-insulation ceramic coating material comprises a combination of twice modified composite ceramic hollow particles, polyurethane modified acrylic emulsion, nano cellulose, a leveling agent and a thickening agent, and by adding a combination of four ceramic particles with different particle size ranges, the heat-insulation ceramic coating material which is good in heat-insulation effect, simple in construction process and excellent in machining performance is obtained; the heat-insulation ceramic coating material can be applied to a passenger car heat insulation plate, has the advantages of being high in heat insulation efficiency, not prone to generating dust and germ pollution, long in service life, excellent in machining performance and easy to clean, and can greatly improve the in-car environment quality and the heat preservation effect of a passenger car.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a heat-insulating ceramic coating material and a preparation method and application thereof. Background technique [0002] At present, the insulation materials of passenger cars mainly use inorganic asbestos materials or organic low-density polyethylene foam materials. Among them, due to the high brittleness of inorganic asbestos materials, it is easy to break into many tiny dusts after being squeezed or collided. These dusts are carcinogenic. Although thermal cotton has no cancer-causing risk of inorganic thermal insulation cotton, as the service life of the bus increases, dust is easy to accumulate on the surface of the thermal insulation cotton, and the gap between the thermal insulation cotton and the aluminum profile is also easy to accumulate dust. It is troublesome to clean up. In wet weather, these dusty surfaces will form a breeding ground for bacteria, cau...
