Description

A kind of liquid thermal isolation film and preparation method
(1) technical field
The present invention relates to energy-saving building materials and application thereof, the heat insulation application and the protection of chemical storage tank surface and pipe surface.
(2) background technology
The sun makes all things on earth be grown and continue for the light and heat of the earth, and sun power is familiar with fully by the mankind as a kind of energy and constantly is used.All there is the effect of the pros and cons the same with anything, excessive sunlight heat has brought many troubles also for the earth, nature and the mankind, even formation disaster: the sun heat radiation of excess makes the appearance temperature of petrochemical complex storage tank reach seventy or eighty degree, and a large amount of raw materials loses because of " size is breathed " that temperature variation forms.In order to keep the safety in production, people have to thicken the steel plate thickness of storage tank, have to adopt spray water to be lowered the temperature to storage tank.Bad change process and even generation insect pest that the temperature of grain depot raises and quickened grain, the labor intensive of having to material resources shorten taking grain out of a granary to sun it the time of grain.The intensification of boats and ships, vehicle is having a strong impact on its performance performance, and refrigeration cool-down has expended the too much energy again, has also brought atmospheric pollution simultaneously.The intensification of factory building and dwelling house has consumed a large amount of electric energy so that people obtain nice and cool in, further aggravated the tropical island effect in city again.U.S. physicist of Chinese origin, incumbent USDOE minister's Steven Chu were said in the climate change symposial in London in 2009: if white is painted on all roofs, road surface and automobile use light application, reflected solar radiation heat in a large number just, use reducing Greenhouse effect, be equivalent to the carbon emission that all automobiles are in the world stopped minimizing in 11 years.
Existing thermal isolation film is mainly used in the heat insulation of the heat insulation or air material of glass surface, all is dispatch from the factory film or plate with regard to compression moulding, and manufacture difficulty is higher, is difficult to be applied to the rough and uneven in surface or big area in surface and decorates.And kind is single, can not satisfy the more market requirement.The present invention relates to a kind of liquid thermal isolation film material, can simply be coated on scraggly body surface, wide in variety, can select matched materials according to unlike material.The heat-proof quality excellence.
(3) summary of the invention
In order to overcome the application limitation of present thermal isolation film, the present invention adopts a kind of novel nano coating material: nano-silicon dioxide hollow sphere clad nano nickel powder, nano zircite or nano titanium oxide can reach extraordinary reflection, radiation effect; Adopt the closed pore ball of the hollow low water absorption of different-grain diameter, conduction that can trap heat; Simultaneously, the high titanium dioxide of selective light reflectivity is as reflection, absorbing material, the optimization of C design, and the coating thickness that makes has improved the dry film area of per kilogram material greatly 150 microns heat insulation and heat control effects that just can reach excellence, provides cost savings.Sunlight reflectivity is greater than 0.91 after testing, and thermal conductivity is less than 0.05W/ (M.K), and the shone thing surface can reach more than 30 degrees centigrade with the standard surface temperature difference.This technology is showing good effect at present by pilot scale aspect storage tank cooling, the building energy conservation.
1, a kind of liquid thermal isolation film and preparation method comprise two parts of primer and surface material:
1. primer: according to required applicator surface properties, preferred different sorts binding agent mainly consists of:
Nano silicon coated powder companion
Production technique: under condition of stirring, add above-mentioned materials successively, behind dispersion, grinding, homogeneous, obtain thick liquid.Above-mentioned nanometer companion needs to be uniformly dispersed through special process.
Preparation technology: can adopt blade coating, brush, roller coating or spraying coating process are constructed, and generally apply about 100 microns of dried film thickness two to four times.
2. surface material:, mainly consist of according to required applicator surface properties:
Nano silicon coated powder companion
Production technique: under condition of stirring, add above-mentioned materials successively, behind dispersion, grinding, homogeneous, obtain thick liquid.Above-mentioned companion need adopt special process to be uniformly dispersed in advance.
Preparation technology: the primer preparation is finished, and is dry more than 12 hours, carries out the surface material coating again, can adopt brushing, and roller coating or spraying coating process are constructed, and generally apply about 50 microns of dried film thickness two to three times.
2, be commercially available common deionized water according to the deionized water described in the summary of the invention 1, described defoamer is the FoamstarA36 and the A10 of Shenzhen Hai Chuan chemical industry; Dispersion agent is the H5040 of extra large river chemical industry and the TCP-8030N of Nuo Puke; Wetting agent is the H140 or the H875 of extra large river chemical industry; Nano silicon coated powder companion and nano titanium oxide companion produce for Beijing Saiterui Science ﹠ Technology Development Co., Ltd.; Reflecting material is the mixture of rutile titanium white powder R960, process white, infrared external reflection agent etc.; Film coalescence aid is the Texnoal of U.S. Yi Siman; Other functional agents are commercially available propylene glycol, Diethylene Glycol butyl ether, biocide mildewcide LXE, ADEKANOL UH420, the AP-10 of ROHM AND HAAS of the AMP95 of LG-DOW, Japan, the DSX3550 of extra large river chemical industry etc.; Binding agent is the pure acrylic resin emulsion K2 of ROHM AND HAAS, the BP-108 of Beijing Proview latex, the shake F500-1 of nation of Dalian, the PTFE of Daikin, Waterpoxy 1455 that German section is peaceful and solidifying agent Waterpoxy 751.
3, coating thickness of the present invention is about about 150 microns, and all material all adopts water-soluble environment protective material, safety non-toxic.But the firm attachment of originally filming is in various substrate surfaces, and not efflorescence more than 20 years does not come off.
