Abstract

The invention discloses a novel thermal insulation building coating, which belongs to the technical field of coating. The novel thermal insulation building coating is prepared with polyacrylate or polymethacrylate as base material and hollow glass beads coupled with fine iron sesquioxide powder as functional filler under the action of initiator by utilizing the emulsion technology, and by utilizing the sunlight and ultraviolet ray reflection functions of the hollow glass beads, the low thermal conductivity of the rarefied gas in the hollow glass beads and the high thermal emissivity of the inverse spinel type structure of the iron sesquioxide, the novel thermal insulation building coating can insulate heat. The appearance of the product is reddish yellow, light red, orange, deep red or inother different degrees of red, and compared with other acrylic ester wall coatings, the novel thermal insulation building coating has the advantages of low density, low viscosity, good rheological property and low shrinkage, and has good thermal insulativity.

Description

technical field [0001] The invention relates to a building coating, in particular to a formula and a preparation method of a novel heat-insulating building coating. Background technique [0002] Traditional architectural coatings for exterior or interior walls mainly emphasize anti-corrosion, anti-fouling, aging resistance, and good self-cleaning properties, but insufficient attention has been paid to thermal insulation performance. As low-carbon life and green life are gradually recognized or accepted by people, it is very important to turn on air conditioners less or not to save electricity for a developing country like ours with serious electricity shortage. So thermal insulation type architectural coating is a better way to realize this ideal. As long as a thin layer of heat-insulating coating is applied on the exterior wall or roof of the building, the indoor temperature can be kept warm in winter and cool in summer, and the air conditioner can be turned on less or not...
