preparation example Construction

[0037] The preparation method of the additive composition of the present invention is a method commonly used in the art, for example, it can be obtained by mixing various components.

[0038] The additive composition of the present invention can be added to any synthetic resin emulsion base paint or solvent-based base paint, so that the paint has excellent thermal insulation performance. At the same time, the additive composition of the invention can be fully mixed with various base paints without changing other physical and chemical properties of the base paint.

[0039]

[0040] The heat-insulating paint of the present invention includes a base paint and the additive composition described above. The heat insulating coating of the present invention comprises the following components by weight: 20-30 parts of base resin; 8-24 parts of pigment; 5-35 parts of filler; 2-8 parts of coating additive; 5-20 parts of far-infrared radiation powder; and 5-15 parts of infrared reflect...

Abstract

The invention discloses an additive composition, a thermal-insulation paint and application thereof. The additive composition comprises the following raw materials in parts by weight: 5-20 parts of coated ceramic hollow microbead, 5-20 parts of far-infrared radiation powder and 5-15 parts of infrared reflection pigment. The coated ceramic hollow microbead comprises a hollow microbead base and a coating. The coating comprises the following components: 1) oxide of titanium; 2) oxide of silicon; and 3) oxides of at least two of Al, Na, K, Ca, Cr, Mn, Fe, Co, Cu and Mg. The additive composition and paint have excellent thermal insulation function.

Description

technical field [0001] The present invention relates to an additive composition, a thermal insulation coating and its application, in particular to an additive composition for thermal insulation and a thermal insulation coating containing the composition. Background technique [0002] Nature transfers heat energy to ground objects in three ways: conduction, convection and radiation. In order to slow down or prevent these heat transfers, it is necessary to install thermal insulation materials on the inner and outer surfaces of buildings to achieve the purpose of improving the thermal environment and saving energy. Thermal insulation coating is a new type of thermal insulation and energy-saving material widely used in the construction industry. [0003] In the formulation system of thermal insulation coatings, in addition to the base material (base resin) and additives (dispersant, defoamer, film-forming aid, etc.), pigments and fillers must also be added. Some of these pigm...
