Abstract

The invention belongs to the technical field of coatings, and especially relates to a production technology for a reflective heat-insulation coating. The production technology comprises the following steps: adding 160-180 parts by weight of water, 2.5-4.8 parts by weight of a dispersant, 4.8-7.2 parts by weight of an antifoaming agent, and 4.8-8.8 a bactericide into a reaction kettle, and stirring uniformly; and then adding 16-24 parts by weight of a film-forming auxiliary agent, 0.3-0.8 part of a thickening agent, 0.3-0.5 part of a pH adjuster, and 1.5-3.2 parts by weight of an anti-freezing agent, adjusting the rotation speed to be 280-380 r / min, and then stirring for 25-30 min, so as to obtain the reflective heat-insulation coating. The produced reflective heat-insulation coating possesses excellent performances and relatively high reflectivity and emissivity, possesses relatively high solar reflection and hemisphere emissivity because of the added nanometer metal oxide, and is capable of reflecting 95% or more of energy in solar heat.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a production process of reflective heat-insulating coatings. 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. [0003] 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 insulation materials are undergoing a ...
