Description
Technical field
The present invention relates to a kind of preparation method of heat reflective heat insulating composite coating, specifically, relates to a kind of preparation method that can shield sun heat radiation and other thermal radiation, have the composite coating that absorbs ultraviolet ray and heat insulating function.
Background technology
The main thermal source of global biosphere is the sun.Solar radiation energy mainly concentrates on the following wave band of 2.5 μ m, and wherein: ultraviolet luminous energy (λ＜0.35 μ m) accounts for 5%, and visible light (λ=0.35～0.76 μ m) accounts for 40%, and near infrared (λ=0.76～2.5 μ m) accounts for 50%, and other wave band heat energy accounts for 5%.These heat energy are by radiation, convection current and conduction, allow global environment absorb heat supply, and global environment also needs heat loose and releases and consumed energy.With the building is example, and the energy consumption of building accounts for 27% of whole society's energy consumption, and wherein door and window accounts for 40% of building energy consumption again in the buildings; The indoor energy expenditure more than 40% in city is in air-conditioning or heating.In China, this energy consumption on the one hand is also to increase greater than 5% speed every year.According to the actual measurement monitoring to sun power, the heat that direct projection in summer sun the subject of knowledge and the object of knowledge produces can reach every square metre per hour 900 watts.By sun power is 300w/m by the heat in the glass inlet chamber per hour
2, 2000 hours meters of annual accumulation sunshine duration average out to, be 600kw/m because of the heat in the solar radiation inlet chamber every year
2According to the transfer law of heat, heat then from body surface to external irradiation be delivered to interior of articles.If can make a large amount of reflections of body surface and radiant heat ray, can stop hotly simultaneously to inner heat conduction, then can avoid or reduce the interior of articles temperature and raise because of the radiation of solar radiation or foreign radiation sources.Theoretically as long as the effect that just can play heat-insulation and heat-preservation is effectively reflected in thermal radiation.
In the prior art, the material relevant with heat-reflecting heat-insulating mainly contains following several: 1) the disclosed reverberation ray of CN1515633A thermal insulating coating, and it is formed by coated three kinds of components of matrix material, caking agent that the reverberation ray forms by reverberation ray characteristics material, hollow beads and loose porous lagging material and surface thereof; 2) CN1546312A is disclosed with SiO
