Description
Technical field
The present invention relates to a kind of preparation method of tapetum lucidum, be specifically related to a kind of preparation method of solar cooker tapetum lucidum of acrylic surface layer.
Background technology
Human use's solar cooker has had the history of more than 200 year, particularly over nearly two, 30 years, countries in the world all successively development and production various dissimilar solar cookers.Especially developing country, solar cooker has been subject to users' favorable comment, and obtains good promotion and application.Solar cooker uses domestic and international state-of-the-art optical theory optimization design, the ripe heat energy of whole Conversion of energy of sunlight can be carried out to cooking and heats up water, can use throughout the year, the various cooking activities such as can meet steaming, stew, boil, boil in a covered pot over a slow fire, one family is general about can save 60% liquefied gas or the coal of 1.5 tons every year.
Solar cooker tapetum lucidum is a kind of pad pasting of aluminizing that is applied to solar cooker, and the principle of solar cooker is exactly according to minute surface reflective mechanism, thereby sunlight is focused at focusing surface and reached a high temperature, and carries out work.Solar cooker tapetum lucidum, reflects sunlight a kind of industrial goods of use exactly.The general reflecting rate of solar cooker tapetum lucidum is more than 80%, and the reflecting rate of very-high performance tapetum lucidum is generally more than 90%, and rub resistance is corrosion-resistant, ageing-resistant. and high brightness, backlight is observed reflect only blue.Adopt vacuum aluminum-coatedly, surface smoothing is highlighted, uses for a long time, and surface is still level and smooth, there will not be diffuse-reflectance.High temperature resistant, 100 degree boiling water soak and scald not dealuminzation.
At present, the solar cooker tapetum lucidum manufacture that domestic market occurs is to utilize PE film or PET film as surface layer, and by vacuum aluminum-coated, the back of the body is coated with acrylic pressure sensitive viscose binder, then the release film of fitting.Because fundamentally do not reach the work-ing life of PE facial mask or PET facial mask 10 years, PE film or PET film transmittance, thermotolerance, humidity resistance, anti-electrostatic, weather resistance, resistance to acids and bases, ageing-resistant also poorer than acrylic facial mask.
In addition, because acrylic facial mask is very crisp, fragile brisement film, acrylic facial mask easily in the course of processing easily because friction produces scuffing, cause solar cooker tapetum lucidum reflector efficiency low.
Summary of the invention
