Embodiment 1

[0034] Take the following components by weight percentage:

[0035] deionized water 26,

[0036] Dispersant 2,

[0037] Rutile titanium dioxide 30,

[0038] 3000 mesh potassium hexatitanate or sodium hexatitanate 31,

[0039] wetting agent 2,

[0040] Ethylene glycol 1.5,

[0041] Propylene glycol phenyl ether coalescent 3.5%,

[0042] Silicone defoamer 1.5%,

[0043] Associative thickener 2.5%,

[0044] Raw paint component weight percent is the acrylic emulsion of 37%,

[0045] The weight percent of raw paint components is 10% filler.

[0046] The filler is 1 part of ultrafine barium sulfate of 1000-1500 mesh, 2 parts of mica powder of 1000-1300 mesh, 3 parts of ultrafine talc powder of 1000-2000 mesh or 4 parts of covering polymer emulsion.

[0047] The preparation method is as follows:

[0048] 1) Add the deionized water into the dispersing kettle, start the high-speed disperser and control its speed at 1600-2500r / min, add the dispersant to the deionized water, di...

Abstract

The invention relates to a reflective insulation energy-saving coating for the external surface of a building. The coating is characterized by comprising the following components in percentage by weight: 15 to 45 percent of deionized water, 0.5 to 5 percent of dispersing agent, 16 to 36 percent of rutile type titanium dioxide, 3 to 35 percent of insulation powder, 0.1 to 3.5 percent of wetting agent, 0.5 to 2 percent of auxiliary film forming anti-freezing aid, 1.5 to 7.8 percent of film forming aid, 0.1 to 1.8 percent of antifoaming agent and 0.5 to 2.5 percent of thickening agent. The reflective insulation energy-saving coating for the external surface of the building effectively resists radiation of heat energy produced by sunlight and is an energy-saving and environment-friendly product; meanwhile, the preparation process flow for the coating is simple, complex equipment is not needed, large-scale processing production is easy to implement, the preparation process is environment-friendly, the conventional insulation system can be partially or completely replaced through thermal performance design calculation, and the potential fire hazard of an external wall insulation system is eliminated.

Description

technical field [0001] The invention belongs to the field of paints, in particular to a reflective, heat-insulating and energy-saving paint used for building exterior surfaces. Background technique [0002] The earth is irradiated by the sun every moment, and the sun has 1.765x 10kJ of energy per second to reach the earth. The huge energy provides the necessary conditions for human survival and life. Human beings are actively developing and utilizing solar energy to save the limited non-renewable resources on the earth. But the strong radiation of the sun also brings some inconvenience to people's life. In many developed countries, the energy used by cooling equipment such as sprinklers, air conditioners, air conditioners and electric fans accounts for 20% of the total annual energy consumption. Example above. Since the 1960s, the rapid development of my country's construction industry, petroleum industry, transportation industry, and weapon industry has required the use o...
