Description
Technical field
The invention belongs to camouflage building color coated metal coating and preparation thereof, using method, belong to the coating of anti-near-infrared camouflage colour coated plate and preparation thereof, using method especially.
Background technology:
Colour coated plate is through successive pre-paint line, at pretreated galvanized sheet (or cold-reduced sheet) surface-coated organic coating, and is solidified into permanent coating, thereby forms the material of construction with good ornamental, protectiveness and mechanical property.This product is used for not only quick construction of construction work, and good endurance, elegant in appearance, has therefore all obtained using widely at industrial circle, civil area.But do not produce colour coated plate process control technology because present pre-paint line does not also possess, limited the application of colour coated plate product on the military architecture engineering with camouflage performance.At present, the most of military engineering (as command post, hutment etc.) that need pretend mostly is to build structure with concrete to form, and manually pretends the application operation at concrete and mortar surface again.This traditional camouflage mode exists tangible deficiency: at first, the structure of the buildings of concrete or brick mix structure and artificial application operation labour intensity are big, and operating efficiency is low; Secondly, the poor durability of back application camouflage coating is prone to and fades, ftractures, sticks up skin and layering obscission, causes the construction work and the camouflage effectiveness lost of life.These deficiencies directly cause pretending engineering brushed again with regard to needs after the very short time, and not only the wasting manpower and material resources gives away one's position again easily.Pretend the application of colour coated plate, can not only overcome the shortcoming of above-mentioned concrete or building with brick-concrete structure, can also give full play to the advantage of this New Building Materials of colour coated plate, effectively improve job schedule, save a large amount of human and material resources.But the application of this New Building Materials palpus solves two big restriction difficult problems: the one, not only be fit to existing pre-application production technique but also have the preparation that near infrared (comprising visible light) pretends the coil coating of performance; The 2nd, adopt the grasp of near infrared (comprising visible light) camouflage coil coating production camouflage colour coated plate production technique and coating performance control techniques.
Summary of the invention:
The 1st technical problem to be solved by this invention provides a kind of new anti-near-infrared camouflage coil coating that satisfies GJB 1887 " anti-visible light near infrared solvent-borne type camouflage paint standard ".
It is the preparation method of above-mentioned coating that the 2nd technical problem to be solved by this invention provides a kind of.
The 3rd technical problem to be solved by this invention is the using method of above-mentioned coating.
The technical scheme of technical solution problem of the present invention is:
