Description
Technical field
The present invention relates to a kind of coating, more particularly to a kind of heat insulation and heat absorption integrative paint, belong to chemical technology field.
Background technology
Thermal insulation coatings are a kind of novel thermal insulation materials, and the one of heat-insulation and heat-preservation is realized by low thermal conductivity and high thermal resistance
Kind coating.Thermal insulation coatings should can be mainly used for heat-insulated or heat preservation in industries such as building, chemical industry, metallurgy, ship, space flight extensively
The occasion of (cold insulation), coating has good adhesive force, available for steel, cast iron, aluminium, copper, magnesium, steel stone material, timber, ceramics, glass
Glass, textile, plastics, paper and various coating surfaces.It is a kind of higher heat-proof insulation waterproof fire retardant anticorrosion insulation of cost performance
The anti-enzyme environment-friendly and energy-efficient coating of acid and alkali-resistance.
Heat-absorbing paint is generally used for solar absorber plate, solar thermal collector etc..Solar energy heating tablet is, it
Including thick base's aluminium sheet, base's surface of aluminum plate coating setting heat-absorbing paint layer, base's aluminium sheet uses the trade mark as 1
The aluminium sheet of series, good heat conductivity, convenient for laser or ultrasonic bonding.It is applied by coating one layer of tool heat absorption in base's surface of aluminum plate
Heat absorption flat plate is made in the bed of material.
The Chinese patent of Publication No. 103360803A discloses a kind of different poly- state solar energy modified silicon solution-selective and inhales
The preparation method of hot coating.It is by waterglass, adds in water stirring, adds in active silicic acid, and Ludox is made after insulated and stirred, then
It adds in 4 and is modified agent emulsion, be stirred to obtain film forming binder；With film forming binder and iron powder, be ground into uniform dispersion to get
To heat-absorbing paint.It solves current solar selectively absorbing coating and prepares that environmental pollution is big, and cost is higher, and weatherability is not
The technical issues of good, but its preparation process is cumbersome, heat absorption efficiency is low.
The Chinese patent of Publication No. 103421367A discloses a kind of thermal insulation coatings, and the thermal insulation coatings include following groups
