Problems solved by technology

However, there are still many disadvantages in the heat-insulating coatings currently used, such as aging and wear after being irradiated by the sun for a long time, which will make the heat-insulating effect of the coating film worse and shorten the service life.

Embodiment 1

[0029] Heat-reflective heat-insulating coating raw material (parts by weight):

[0030] 15 parts of water, 15 parts of acrylic emulsion, 20 parts of hollow glass microspheres, 6 parts of cobalt blue, 20 parts of titanium dioxide, 20 parts of aluminum silicate, 25 parts of calcium carbonate, 5 parts of sodium polyacrylate, 15 parts of thermal insulation synergist, Antifreeze 1.5 parts.

[0031] The heat insulation synergist is obtained by uniformly stirring and mixing zirconium dioxide, silicon dioxide and boron trioxide in a mass ratio of 1:1:1.

[0032] The antifreeze is obtained by stirring and uniformly mixing 1,3-propanediol, isopropanol, and ethylene glycol in a mass ratio of 1:1:1.

[0033] Preparation method of heat-reflecting heat-insulating coating: Water, acrylic emulsion, hollow glass microspheres, cobalt blue, titanium dioxide, aluminum silicate, calcium carbonate, sodium polyacrylate, heat-insulating synergist, and antifreeze are used in a cantilever double-helix...

Embodiment 2

[0035] It is basically the same as Example 1, except that the heat insulation synergist is obtained by uniformly stirring and mixing zirconium dioxide and boron trioxide at a mass ratio of 1:1. The heat-reflective heat-insulating coating of Example 2 was obtained.

Embodiment 3

[0037] It is basically the same as in Example 1, except that the heat insulation synergist is obtained by stirring and mixing silicon dioxide and boron trioxide at a mass ratio of 1:1. The heat reflective heat insulating coating of Example 3 was obtained.

Abstract

The invention discloses a heat-reflecting thermal insulation coating, which is prepared from the following raw materials in parts by weight: 10 to 20 parts of water, 10 to 20 parts of acrylic emulsion, 15 to 25 parts of hollow glass beads, 5 to 15 parts of a pigment, 15 to 25 parts of titanium dioxide, 15 to 25 parts of aluminum silicate, 20 to 30 parts of calcium carbonate, 3 to 9 parts of sodium polyacrylate, 10 to 20 parts of a thermal insulation synergist and 0.5 to 5 parts of an antifreeze agent. According to the heat-reflecting thermal insulation coating, the heat of the sun can be effectively prevented from being accumulated on the surface of an object for heating, heat radiation for cooling can also be automatically implemented, and the heat-reflecting thermal insulation coating is high in antibacterial and anticorrosive performance and efficiency and convenient to construct.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a heat-reflecting and heat-insulating coating. Background technique [0002] The current energy consumption of buildings accounts for 30% of the energy consumption of the whole society, most of which is due to the use of air conditioners. In hot summer, the sunlight is directly irradiated to the roof and transferred into the house through roof absorption to increase the indoor temperature. According to statistics, the roof receives the longest sunshine time, and the heat absorbed by the roof accounts for 46% of the total heat absorbed by the house. Therefore, research and development Building thermal insulation coatings have significant economic, environmental and social benefits. [0003] Brushing the reflective heat-insulating paint on the building surface can reduce the hot summer and cold winter and hot summer and warm winter areas of the building, form a low-radiation heat...
