DB-16T Thermal insulation coating
DB-16T with the increasingly exhausted of the earth's energy, environmental protection and energy saving become the theme of this era. In the era of scientific research and technological development, energy saving and consumption reduction, and economic efficiency improvement are one of the main breakthrough directions, even fire paint technology is no exception.In recent years, the research and development of building thermal insulation coating - reflective thermal insulation coating has made a great breakthrough in energy saving.To understand - reflective insulation coating, we need to start with the formulation of reflective insulation coating.
The formulation of reflective thermal insulation coating is mainly composed of base material, thermal reflective pigment, filler and auxiliary agent. It is a new type of fire-fighting equipment which can achieve the purpose of thermal insulation by reflecting sunlight efficiently.Thin layer thermal insulation reflective coating is the representative of this kind of coating. It is mainly used in various occasions requiring thermal insulation in the field of construction engineering, that is, high reflective thermal insulation coating is used on the surface of peripheral protective structure, which can reduce the absorption of solar radiation heat by the building, prevent the temperature rise caused by the absorption of solar radiation on the surface of the building, and also reduce the heat flow to the roomIn order to achieve the protection and fire protection of the building.
According to the heat insulation mechanism of reflective heat insulation coating.
Ⅱ、There are mainly three types of reflective heat insulation coatings
Barrier insulation coating:
Insulation is achieved by impedance of heat transfer.In the preparation of coatings, the main materials are low thermal conductivity materials and air with low thermal conductivity after coating film forming.The commonly used heat resistant fillers of the reflective heat insulation coating include hollow glass bead, hollow ceramic powder, hollow fiber, sepiolite, vermiculite, perlite, etc.
Thermal reflective insulation coating:
It mainly reflects the spectral energy of sunlight in the range of 400-1800nm to achieve the heat insulation effect.Its reflective material is nano material.
Radiation insulation coating:
Mainly through the absorption of sunlight and heat at a certain wavelength into the air for insulation.Its formula material is a variety of metal oxides, such as iron oxide, manganese dioxide, cobalt oxide, copper oxide and other reflective spinel dopants.The above three are just the most basic classification. In many cases, we can also composite the reflective and thermal insulation coatings with the above functions to form multifunctional thermal insulation coatings such as those with both barrier and reflection functions, which is also the future development trend of reflective and thermal insulation coatings.
What's more precious is that the reflective heat insulation coating has the dual functions of decoration and heat insulation, which belongs to the functional coating.Therefore, this kind of coating has been widely used in the field of construction engineering, mainly used for the reflection and heat insulation of roof and wall, and also widely used in the granary, and the application field and use place of the reflection and heat insulation coating are constantly expanding. With the infinite increase of the demand for building energy saving in the future, its attention will inevitably show a geometric progression growth!With its own superior performance, reflective heat insulation coating has aroused strong market response as soon as it was published. Even the state has issued the requirements of reflective heat insulation coating standard (JC / t1040-2007): solar reflectance is not less than 85%, hemispherical emissivity is not less than 83%.So as to standardize the market of reflective heat insulation coating.
Ⅲ、 Construction proportion
Paint: diluent (1:0.3-0.5)
1.The paint and diluent shall be sealed in a cool place to prevent fire, leakage, sun, high temperature and fire.
2. The storage period of coating is more than one year.
3. After opening the tank, the paint shall be stirred evenly to prevent the color difference caused by the pigment sinking.
4. If there are dust, particles, oil and other attachments on the surface of the workpiece, it will damage the appearance, so it should be wiped clean before spraying.
5. Due to different plastic substrates, the test shall be conducted before spraying to avoid affecting the adhesion of the paint.
6. During the construction, please do a good job in labor protection, wash the skin contact coating with washing powder and water, and seek medical help in case of discomfort.
