Abstract

The invention relates to the technical field of a heat-insulating material, and specifically relates to a heat-insulating coating which contains 1-25wt% of composite tin antimony oxide heat-insulating material, wherein the composite tin antimony oxide heat-insulating material is prepared from hollow beads, tin tetrachloride and antimony trichloride according to a ratio of 0.5-5g:0.015-0.06mol:0.00125-0.00378mol. The preparation method comprises the following steps: preparing a crystal seed; preparing a composite tin antimony oxide precursor; calcining the composite tin antimony oxide precursor to obtain the composite tin antimony oxide heat-insulating material; and preparing heat-insulating paint, and applying to obtain the heat-insulating coating. The composite tin antimony oxide heat-insulating material has the advantages of good heat insulation effect, simple and easily-acquired raw materials and low cost, reduces the transmission of heat, lowers the temperature and saves the cooling cost. By adding ammonia water used as precipitant, tin antimony oxide can be firmly attached to the surfaces of the hollow beads, thereby ensuring that the composite tin antimony oxide heat-insulating material has long service life and good heat insulation effect; and the heat-insulating coating has good weatherability, high adhesive capacity and fine heat insulation effect.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a thermal insulation coating, and also to a preparation method of the thermal insulation coating. Background technique [0002] In the distribution of solar energy, visible light and near-infrared bands account for most of the energy, accounting for 44% and 51% of the total energy respectively. Therefore, energy-saving coatings are mainly achieved by improving the reflectivity of sunlight in visible and near-infrared bands purpose of cooling. Infrared reflective heat insulation coating is a new type of functional coating, which can effectively reflect near-infrared light in sunlight, prevent heat transfer from the source, and effectively reduce the surface and internal ambient temperature of the coating, thereby achieving improved work Environmental protection, the purpose of reducing energy consumption, so it is widely used in construction, petroleum, tra...
