Description
Technical field:
The present invention relates to technical field of coatings, specifically is a kind of used solar heat reflecting and heat insulating coating and preparation technologies such as outer surface of building (comprising body of wall and roof) and industrial storage tank that are used for.
Background technology:
Human active development sun power is to save limited resources.But the heat that intense radiation produced of the sun brings inconvenience also for people's life, and in developed country, the used energy of cooling system such as cold air unit, conditioning unit and electric fan account for more than 20% of annual total energy consumption; In China, the energy of these devices consume is then up to about 41%, and annual the trend that increases progressively arranged all.Cause the too high loss of these energy, the heat-insulation and heat-preservation measure of taking with buildings has very big relation.
In order to reduce the rising of outside atmosphere (mainly being sun power) to buildings and industrial tank inside temperature, traditional method is to consider from reducing the thermal conduction rate aspect, adopts the little lagging material of heat transfer coefficient to reduce sun power to the thermal conduction in buildings and the storage tank.This quasi-tradition lagging material is that it is main reducing thermal conductivity and heat transfer by conduction with raising gas phase voidage.The fiber-like lagging material will make transmission of heat by convection and radiative transfer reduce in environment for use, and thicker coating must be arranged; Section bar class inorganic heat insulation material is wanted assembling construction, has shortcomings such as seam is many, influence is attractive in appearance, water-repellancy is poor, work-ing life is short.And in case heat energy imports the internal space into, even outside temperature goes down, heat energy is difficult to discharge.
Reflective insulation, shielding sun heat radiation are a kind of novel heat insulation modes, can solve that many factory buildings and house roof under the solar irradiation are laid black waterproof layer and the internal high temperature brought.Especially during the broiling summer, can effectively reduce the intravital temperature of coating sealing under the solar irradiation.
Solar heat reflecting and heat insulating coating mainly be adopt good weatherability, water tolerance is strong, ageing resistance is strong, have strong cohesive force and elastic and can be with the insulation filler, reflect the good film forming material of filler intermiscibility, select light weight hollow, high temperature resistant, thermal resistance big and have the filler of good reflection and radiativity, refraction coefficient height, surface smoothness height, heat reflectivity and the high superfine powder of radiant ratio are suitable as the reflection filler, constitute low radiative transfer layer with the film forming base-material, can effectively cut off the transmission of heat.Heat reflectivity can reach 85%.This thin layer heat insulating reflecting coating and the compound use of porous material can be used for different places applications such as buildings, car and boat, petrochemical industry oil tank equipment, grain depot, freezer, freight container, pipeline.
There is following problem mostly in prior art:
1 adopts solvent based coating, unfavorable for environmental protection;
2 used vacuum micro-balls can not disperse in system fully, thickening, stratified phenomenon occur at lay up period;
Though 3 have added heat insulation material, but heat still increases in time and increases.
Summary of the invention:
