Experimental example 10
To certain chemical plant office building wall and roof application with the coating of pressing embodiment 10 gained of the present invention after, stop using electric fan in this building after, indoor have pleasantly cool sense by comparison with the office that does not use coating of the present invention significantly.Room temp obviously reduces.Roofing is through field inspection, and the temperature difference is very big under the sunlight.
Coating compound of the present invention can cover with paint, lacquer, colour wash, etc. in as dwelling house, office building, auditoriums, hotels, factory building, freezer, plant etc. be with the concrete main material buildings top and around outer wall surface, reaching good heat-insulating cooling effect, few with or without air-conditioning; Also can be coated on the outer surface of equipment such as industrial metal jar, groove, pipeline, as oil depot, oil tank, oil groove, liquefied gas class spherical tank, chemical pipeline and refrigerator car, ship etc., and need not with cryogens such as cold water spray, to prolong the work-ing life of equipment, the Ordinary Wear and Tear of minimizing oil plant etc., save energy.What coating composition of the present invention can be used for all kinds of vehicles such as car, ship, facility, place etc. again falls the heat drop temperature; Even also can be painted on each based article member outer surface such as the plastics that need directly heat insulation and heat control in thermal source radiation, conduction scope, wood.
Through the buildings of outside surface brushing coating composition of the present invention, industrial equipments such as oil tank and car, ship etc. can be effectively, infrared radiation, the conduction heat of thermals source such as isolated daylight significantly, reduce temperature to reach about 10 ℃, and be an ideal heat insulation and heat control coating.
In addition, coating composition strong adhesion of the present invention, wear resistance is good, and the good weathering resistance of tool again can stand stern climate conditions such as ultraviolet ray, hot and cold and Exposure to Sunlight rain and dew, and its effective service life, reached more than 5 years.
Moreover coating composition of the present invention preparation is simple, easy to use, with methods such as common brushing, roller coating or spraying get final product, generally wet, build is respectively 300 and 100 μ m.But as film thick slightly also harmless, phenomenons such as wrinkling, sagging can not take place.Coating composition of the present invention behind coated about 15~30 minutes be surface drying, 1-1.5 hour is all dry, also is applicable to the coating decoration that the construction period requirement is short.Again, coating composition recoatability of the present invention is good, as brushing again on the old film of this coating, then because of the sequestering action of solvent etc., can increase the adhewsive action between new old coating film, makes new old coating film fuse one, plays the effect of repairing sth. old and making it as good as new.
At last, film coated surface of the present invention is inferior photosensitiveness, certain ornamental of tool, and it also has certain Corrosion Protection to the metal outer surface.
Through adding an amount of thickening material, coating composition of the present invention can be stored 2 years at normal temperatures to 3 years.The validity period of filming of coating of the present invention is more than 5 years.
