The characteristics of nano transparent thermal insulation coating are as follows:
① Thermal insulation
Nano transparent thermal insulation coating can effectively block infrared rays and ultraviolet rays in sunlight from entering the room through the glass, block more than 99% of ultraviolet rays and block more than 75% of infrared rays, which can reduce the indoor temperature by 3-5℃ and the temperature of the sunned object by 6- 10℃.
② Transparency
8- 10? The visible light transmittance of the micro-film layer around m is as high as 70%, which does not affect the field of vision.
③ Energy saving
Nano-transparent thermal insulation coating has thermal insulation effect, which prolongs the fluctuation of indoor temperature and the balance of outdoor temperature, reduces the frequency of cold and hot air conditioning, and saves energy consumption of air conditioning by 25-35%.
④ Environmental protection
Nano transparent thermal insulation coating is a kind of water-based coating, which does not contain TVOC, free formaldehyde, lead, chromium, cadmium, mercury and other harmful substances. Environmental protection, in line with national environmental quality standards, is a new type of environmental protection coating.
⑤ Health
Nano-transparent thermal insulation coatings can prevent ultraviolet rays from fading and aging indoor items such as furniture, fabrics, carpets, curtains and murals, and prevent diseases such as skin cancer and cataract induced by ultraviolet rays.
2. The coating that plays the role of heat insulation on the building surface is called heat insulation coating, which can be divided into transparent heat insulation coating and opaque heat insulation coating according to different application occasions; According to the thermal insulation mechanism, thermal insulation coatings can be divided into three types: barrier thermal insulation coatings, reflective thermal insulation coatings and radiation thermal insulation coatings.
The main raw materials of the coating are nano hollow beads, advanced emulsion, titanium dioxide and other substances, in which the content of nano hollow beads in the coating should be at least 80%, so that a three-dimensional network hollow structure connected by closed-hole beads can be formed on the surface of the object after coating, and a static air mass can be formed between nano hollow ceramic beads and beads, that is, a heat insulation unit. The thermal conductivity of the coating can reach 0.04W/m.K, which can effectively prevent heat conduction and has excellent thermal insulation performance. The thermal insulation grade of the coating reaches R-30. 1, and the thermal reflectivity is above 90%. It can reflect a lot of infrared rays, prevent infrared rays from heating objects, effectively inhibit the radiation and heat conduction of the sun and infrared rays, and the heat insulation inhibition efficiency can reach about 90%.
