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, and the various dissimilar solar cooker of countries in the world all successively development and production.Especially developing country, solar cooker receives the favorable comment of users, and obtains good promotion and application.Solar cooker uses domestic and international state-of-the-art optical theory optimization design, ripe for whole Conversion of energy of sunlight heat energy can be carried out cooking and heats up water, can use throughout the year, various cooking activities such as can meeting steaming, stew, boil, boil in a covered pot over a slow fire, one family is general approximately can save the liquefied gas of 60% or the coal of 1.5 tons every year.
Solar cooker tapetum lucidum is that the one being applied to solar cooker is aluminized pad pasting, and the principle of solar cooker is exactly according to minute surface reflective mechanism, is carried out focusing on thus reaching a high temperature at focusing surface by sunlight, carries out work.Solar cooker tapetum lucidum, carries out a kind of industrial goods reflected exactly by sunlight.The general reflecting rate of solar cooker tapetum lucidum more than 80%, the reflecting rate of very-high performance tapetum lucidum generally more than 90%, rub resistance, corrosion-resistant, ageing-resistant. high brightness, backlight observes reflect only blue.Adopt vacuum aluminum-coated, 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, not dealuminzation is scalded in 100 degree of boiling water leachings.
At present, the solar cooker tapetum lucidum manufacture that domestic market occurs utilizes 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 release film of fitting.Because the work-ing life of PE facial mask or PET facial mask does not fundamentally reach 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 easily produces scuffing because of friction in the course of processing, causes solar cooker tapetum lucidum reflector efficiency low.
