The paint film fundamental property of the reflective heat-insulation paint of the embodiment of the invention is seen table 1
Table 1
The construction technology of the reflective heat-insulation paint that the embodiment of the invention makes is following:
Construction process is: metope base treatment → scrape (smearing) be coated with flexible waterproof putty 2-3 all over → roller coating exterior wall seal coat → snap the line, lattice, tape → roller coating reflective heat-insulation paint → spraying coating varnish.
The concrete operations step is:
(1) processing base level: before base treatment, body of wall needs the maintenance of certain hour, and the curing time in general new cement wall surface winter is 28 days, and the curing time in summer is 14 days.Maintenance is arrived the pH value of basic unit less than 10, and water ratio carries out processing base level again after 10%;
Should thoroughly remove loose, peeling, hollowing, atomizing basic unit before the base treatment, then, remove pollutents such as dust, greasy dirt;
(2) blade coating flexible waterproof putty:
Repair metope with flexible waterproof putty, the local levelling in first road is filled up big hole and slit with putty or gap-filling glue, treat the putty drying after, detail sanding is completely criticized putty again and is made basic unit smooth.One time blade coating thickness should not surpass 0.5mm, divides twice above construction; Per pass was not less than 5 hours pitch time; (general 4-6 hour) polishing was in time revised after per pass putty blade coating finished.The flexible putty total thickness is controlled at 1.0～1.5mm;
Flexible waterproof putty is a cement system, need carry out maintenance equally, and general curing time is 14 days, to the pH value less than 10, water ratio can carry out the construction of next process after 10%.
(3) brushing seal coat:
After treating that putty reaches requirement, should basic unit be polished flat before the brushing, the cleaning floating dust, hair rolls and should keep clean, and brushes watersoluble closed priming paint one time, brushes evenly, and the brush of leakage phenomenon never can be arranged.Forbid converting water when watersoluble closed priming paint is constructed, guarantee that simultaneously seal coat does not receive any pollution, is not with any color;
(4) roller coating reflective heat-insulation paint:
Treat can adopt after the abundant maintenance of putty layer method of roll coating to divide all over the construction thermal insulating coating, treat next time of constructing again after the first pass thorough drying, converting the water yield during construction is 10-20%, generally constructs just to become alive about 3 times;
(5) spraying coating varnish:
(general fine day kept 3 days at least) can spray coating varnish after treating the thermal insulating coating complete drying, notes keeping viscosity during construction, air pressure, and the spout size is consistent, notes prevention sagging phenomenon;
The coating varnish construction time is not converted any thinner, must spray evenly and comprehensively, generally will spray twice, and phenomenons such as the spray of leakage never can be arranged;
(6) construction precautions
Construction environment: guarantee that envrionment temperature should be greater than 5 ℃, relative humidity is less than 70%, and the weather of no strong wind is construction down, and rainy day or the weather that will soon rain also must not be constructed, and pay close attention to weather-forecast during construction more;
(7) accumulating requires:
1. condition of storage: coating ventilate, dry, temperature stores under 5～35 ℃ environment;
2. quality guaranteed period: effective shelf lives of product is 1 year;
3. transport condition: transportation is handled by " non-dangerous goods transportation rule ".
In sum; The reflective heat-insulation paint of the embodiment of the invention; It is a kind of water-borne coatings of single-component; The superfine little cenosphere vacuum layer that tight multistage arrangement forms in coating has extremely strong reflection and iris action to solar radiant heat in the coating, can effectively reduce radiative transfer and transmission of heat by convection, thereby reduce the thermal equilibrium temperature of body surface.This coating is nontoxic, and weathering resistance is good, has waterproof, anti-flaming function concurrently, has high wear resistance and cohesive strength and excellent toughness.Compare with common coating; Be not only for realizing a certain protection function; Coat a resist for material requested (or fender), but from modernized demand quality, with multifunctional protection, energy-efficiently, long-acting the functional coat that modern coating complex art merges such as continue.Its coating is the functional layer that is rich in elasticity, ductility and ventilation property after the operation.Be coated in architectural after, have the function that flashes back the sunlight, can form a resist, be a kind of multifunctional protection, energy-efficient, long-acting lasting functional coat, the coating of formation is a kind of functional coating that is rich in elasticity, ductility and ventilation property.Make space and facility container cool in summer and warm in winter, reduce " tropical island effect ", reduce air conditioning energy consumption, energy-saving effect is remarkable.Compare with common coating, 20 ℃ of the highest reductions of surface temperature, internal temperature reduces by 5～10 ℃.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto, and also because of the succession of each embodiment the present invention is not caused any restriction, and any technician who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
