Abstract
The present invention provides a kind of insulating moulding coating and preparation method thereof, 1-2 parts of the tablet including 5-6 parts of 20-30 parts of 40-50 parts of polyester resin, colorant, aerosil, coated with rare earth oxide by weight ratio and 20-25 parts of petro chemical solvent.The present invention can be improved TSR to provide high cooling effect.
Description
Technical field
The present invention relates to insulating moulding coating field, particularly relevant insulating moulding coating and its manufacturing method containing rare earth oxide.
Background technique
It is strong with the tellurian torrid zone and subtropical zone, summer sunshine.Each position of building by sunlight irradiate and
Heat up accumulation of heat.Building absorbs thermal energy and is gradually passed to interior, causes temperature to rise, and then increase its air conditioning requirements, causes summer
Electricity usage amount hits new peak repeatly.
Building envelope structure is mainly that window, roof and exterior wall are constituted.The heat loss that shell enters accounts for whole building
The 74% of air conditioning electricity, ratio is very high.For general house, there are about 40% solar thermal energies to be entered by roof and exterior wall
Interior, the two building materials used may be by insulating moulding coating and obstruct heat, avoid thermal energy from entering the room and reach cooling
Purpose.
Insulating moulding coating is mainly used in the coating of building material surface, and opaque section is to the energy conservation characteristic of shell building materials
Solar thermal energy is avoided to enter the room, it is necessary to improve the total sun light reflectivity (TSR) of coating, avoid absorbing light.If any the sun
Light absorption generates, it is necessary to which the capacity of heat transmission for reducing coating avoids light that substance can be allowed to generate absorption, and is converted into thermal energy and makes
Rise at room temperature.From another perspective, building origin of heat includes top, transverse direction and lower section, it is characterised in that hot spoke
Penetrating with thermal convection is main source.So good heat insulating coat design needs high sun light reflectivity and high radiation emission rate, and
In conjunction with low heat conduction coefficient building materials, structure trunk temperature is reduced, makes the load reduction of cold air, while reducing the discharge of hot gas,
Reach carbon reduction.
Black surface often absorbs 90% up to solar thermal energy, and therefore heating.On the other hand, white surface only absorbs
The 25% of solar thermal energy, and it is easy to keep relatively nice and cool.But a white surface not always selection, multifarious color, especially
Dark-coloured veil certain places there is still a need to.The commercially available pitch-dark coating main component in the U.S. is carbon black, sun light reflectivity
Less than 15%, do not have heat-insulated efficiency.The black pigment product 10C909A that Shepherd color company, the U.S. delivers, sunlight are anti-
The rate of penetrating is about 25%, and sun light reflectivity is higher than conventional carbon black.Although the black pigment that Shepherd color company, the U.S. delivers
Product can promote TSR, and based on the reasons why saving the energy, the heat-insulated of high cooling effect is provided for can be further improved TSR
Coating has great demand to unite.
Summary of the invention
