Abstract
The invention relates to a heat-insulation porcelain-imitating coating and a production method thereof. The heat-insulation porcelain-imitating coating is prepared from self-prepared powdery microencapsulated heat-insulation particles and heat-insulation porcelain-imitating emulsion as the base materials, and other optional accessories. The heat-insulation purpose is realized by a principle that gases with good heat-insulation property are wrapped to form an empty capsule so as to reduce the thermal conductivity of materials and insulate heat, and the coating has a good heat-insulation effect and favors energy conservation and consumption reduction. The mixed powdery microencapsulated heat-insulation particles and heat-insulation porcelain-imitating emulsion are uniform and dense after being mixed, then are uniformly coated on the surface of an object and dried to form the coating with porcelain-imitating performance and sand-wall-like decorative effects, and the obtained coating product has multiple functions and decorative effects.
