Abstract

The invention discloses an enhancement type heat isolating reflective coating. The coating consists of a bottom layer, a middle layer and a face layer; paint of the bottom layer is prepared from, by mass, 5-10 parts of epoxy resin, 15-25 parts of anti-rust pigment, 20-40 parts of inert filler, 5-10 parts of modified ketimine, and 15-35 parts of solvent A; the paint of the middle layer is prepared from, by mass, 10-15 parts of epoxy resin, 10-20 parts of flaky filler, 15-35 parts of hollow glass bead, 10-15 parts of hydroxyl curing agent, and 15-35 parts of solvent B; the paint of the face layer is prepared from, by mass, 40-50 parts of film former resin, 5-15 parts of nanometer metal oxide, 10-15 parts of rutile type titanium dioxide, 15-20 parts of weather fastness curing agent, and 10-20 parts of solvent C. The coating shows the enhancement effect of the heat isolating reflective performance while also has good corrosive resistance.

Description

technical field [0001] The invention belongs to coating technology, in particular to an enhanced heat-insulating reflective coating. Background technique [0002] As a new type of energy-saving material, thermal insulation coating can effectively reflect and block the energy of sunlight, significantly reduce the temperature of building exterior walls, roofs and indoors, and reduce the energy consumption of refrigeration equipment such as air conditioners. The use of heat-insulating coatings can not only improve the working environment but also significantly save energy, and the heat-insulating coatings are convenient for construction and have decorative effects, so they are widely used in the construction field. [0003] With the continuous strengthening of social supervision and inspection on safety and environmental protection issues, coupled with the fact that enterprises consciously improve the effect of energy saving and emission reduction in the operation process of fa...
