Description

Indoor heat-reflecting heat-insulating diatom ooze and preparation method thereof
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of indoor heat-reflecting heat-insulating diatom ooze and Preparation method.
Background technology
Solar energy is the necessary requirement of human survival and life, but the life band of the mankind is also given in strong radiation Serve inconvenience.Such as sunlight in summer irradiate on a metal plate, its surface temperature up to 70-80 DEG C, as This will certainly bring inconvenience and cause material damage.In urban area, dark asphalt road and pitch room Top etc. can absorb the heat from the sun, forms so-called " heat island " effect, makes city temperature than ground, rural area District exceeds about 1-3 DEG C.
Exterior wall to be improved and roof insulation performance, major measure has: (1) improves building thermal technology property Energy;(2) improve the reflectance of outer surface, reduce the heat of incoming indoor;(3) outer surface is improved Emissivity;(4) improve the thermal capacity of roofing, reduce the mode such as heat of incoming indoor.
Under conditions of building external structure determines, there is high sunlight reflectivity and the roof of high emissivity Study hotspot with exterior wall coating becomes architectural energy saving system, has been widely used at building surface.Instead Penetrate insulating moulding coating and can play significant cooling-down effect in summer, thus reduce energy consumption of air conditioning in summer.Pass through It is the most most effective, the easiest with emissivity that brushing heat-reflecting insulating coating improves building superficial reflex ratio Mode.The generally rutile TiO in building face coat2Can strongly absorb the ultraviolet in sunlight, Reduce its destruction to coating paint film.If can be gone back by ultraviolet reflection, protected effect can be more preferable, but This realizes highly difficult for nonmetallic materials are such as coating.So we generally consider visible reflectance Maximizing than with near infrared light reflectivity, these two parts contain the solar irradiation energy of 95%.
The feature of ordinary hot reflective coating be surface color be white or light, can be used for the flat of commercial facility Aspect, low gradient roofing and exterior wall.Overhead infrared photograph clearly illustrates that ground surface temperature has the biggest difference Different.This species diversity is mainly caused by the reflection on surface and radiation characteristic.High reflection, the table of high radiation Face " the coldest ".Actually light color and dark surface is all likely to be of high radiance, and traditional height is warm The coating of reflectivity the most always white or light color.But in actual applications, light color or white are coated with There is the shortcomings such as stain resistance is poor, weatherability difference in material paint film, after using a period of time out of doors, and can be because of Coating surface is dirty, variable color causes heat reflection performance to be greatly reduced, it is often more important that light color or color white Dull, it is impossible to meet and decorate diversified requirement.
The invention provides a kind of indoor heat-reflecting heat-insulating diatom ooze, there is the heat reflection cooling effect of excellence Really.
