Abstract

The invention discloses an interior wall reflection and heat insulation coating and a preparation method thereof. The coating comprises, by weight, 20-35 parts of a modified polyurethane emulsion, 0.1-0.2 part of a PH adjusting agent, 0.4-0.8 part of a dispersing agent, 0.3-0.6 part of a defoaming agent, 0.1-0.3 part of a wetting agent, 1-2 parts of an antifreezing agent, 1-3 parts of a coalescing agent, 0.5-2 parts of a thickening agent, 0.05-0.15 part of a corrosion remover, 5-20 parts of titanium dioxide, 5-25 parts of coarse whiting and 5-15 parts of water. The interior wall reflection and heat insulation coating can be cooperated with an exterior wall reflection and heat insulation coating and an exterior wall heat insulation and preservation board, a building is helped to have the better heat insulation and insulation effect, and the building saves more energy and is more environmentally friendly. Meanwhile, the problem that the stability is poor due to the fact that hollow heat insulation materials are added in other reflection and heat insulation coatings is well solved.

Description

technical field [0001] The invention relates to a reflective heat-insulating coating for interior walls and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] The deterioration of the earth's environment and the rapid depletion of resources are two major worldwide problems faced by human beings. The rapid expansion of the city has intensified the pressure on the environment and resources. Modern buildings occupy the land while consuming more and more resources, and cause a serious urban heat island effect. The energy saving of buildings has attracted attention, and the research on reflective and heat-insulating exterior wall coatings has made great progress, which has good reflective and heat-insulating effects while satisfying the aesthetics. However, the reflective heat insulation function of interior wall coatings has rarely been paid attention to. Compared with exterior wall coatings, interior wall reflective heat ...
