Inorganic heat insulation material will carry out assembling construction, and that there are seams is more, damages the defects of beautiful, waterproofness is poor, service life is short.For
This, people are seeking always and are studying a kind of new material that can greatly improve thermal insulation material heat insulating reflecting performance.
Novel space insulation reflection enamel coating (Therma-Cover), the material be by it is some be suspended in it is micro- in inertia latex
What small ceramic particle was constituted, it has the thermal properties such as high reflectance, high radiant rate, low thermal conductivity, low heat storage coefficient, has
Brilliant heat insulating reflecting function.This hitech materials promote the use of the people by space industry, are used in building and industrial plants,
And exported, in some large scale industry facilities.Building energy conservation is one of emphasis of energy conservation, and exterior insulation has become
For the major product of building energy conservation.Area when for Thermal Design based on keeping the temperature, such as severe cold area and cold district, outside exterior wall
It is not only reasonable to keep the temperature, but also is applicable in, and development is very fast.And heat-insulated hot summer and warm winter region is generally only considered when for Thermal Design,
Or there is further perfect sky in hot-summer and cold-winter area when Thermal Design based on heat-insulated, current some exterior insulations
Between.According to house building enclosure solar radiation equation of heat balance, for the climatic characteristic of different regions, reasonably select and using each
Kind heat insulating coatings, form compound system, had not only kept the temperature but also heat-insulated, achieve the purpose that indoor thermal environment is comfortably and energy-saving.
Coating main raw material(s) is the material compositions such as nano-hollow microballon, advanced lotion, titanium dioxide, wherein the nano-hollow in coating
Microballon content will can at least be formed in body surface after 80% or more, such coating application and be linked together by closing microballon
Three-dimensional network hollow structure, formd between such nano-hollow ceramic microbead and microballon one by one fold folder still air
