Abstract

The invention discloses non-homogenous low-carbon microlite insulating mould coating, and belongs to the field of coating. The coating is prepared from the following components in parts by weight: 100-110 parts of deionized water, 20-40 parts of microcrystalline thermal-insulating nano-powder, 2-3 parts of cellulose, 1-2 parts of a neutralizing agent, 0.5-2 parts of a defoaming agent, 10-20 partsof an antifreezing agent, 1-2 parts of bactericide, 5-15 parts of silicone acrylic emulsion, 10-15 parts of a coalescing agent, 5-8 parts of filler, 2-5 parts of a thickening agent, 700-750 parts of reflective colorful sands and 4-6 parts of other additives. Microcrystalline thermal-insulating nano-powder and reflective colorful sands are added into the coating, so that the thermal insulating andreflecting performance of the coating can be effectively improved, and building energy loss can be reduced. Furthermore, the preparation method of the non-homogenous low-carbon microlite insulating mould coating is simple, and is suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of coatings, more specifically, it relates to a non-homogeneous low-carbon microcrystalline heat-insulating coating and a preparation method thereof. Background technique [0002] At present, reflective heat insulation coatings have been more and more widely used in buildings. Generally speaking, under the same base material conditions, pigments and fillers play a leading role in the reflective heat insulation effect of reflective heat insulation coatings. One of the keys. The use of coatings with heat insulation function on the exterior walls of buildings can not only realize the original decoration, protection and anti-mildew functions of the coating, but also make the coating have the function of heat insulation, keep the indoor temperature constant, increase the temperature difference between indoor and outdoor, Reduce heating energy consumption in summer and reduce heating costs in winter. At present, thermal ...
