Problems solved by technology

[0009] Therefore, it is necessary to develop a new type of nano-fluorocarbon transparent coating with superior performance to overcome the shortcomings of the previously developed transparent heat-insulating coatings, which have heat insulation but poor transparency, or are transparent but have poor heat insulation, so that they can be transparent while having high transparency. Also has better thermal insulation

Abstract

The invention discloses a preparation process of a functional fluorocarbon coating with insulating, self-cleaning, weather-resisting and transparent functions, wherein the preparation method comprises the steps that: a stable aqueous slurry is prepared by anatase nanometer TiO2 and nanometer tin-antimony oxide (ATO); the slurry is added to a fluorocarbon emulsion or a mixed emulsion of fluorocarbon emulsion and silicone acrylic emulsion (styrene-acrylic emulsion) under the action of various assistants; the assistants mainly comprise a film-forming assistant, a wetting agent, a dispersant, a thickener and an antifoaming agent; the rest part is de-ionized water. The invention also comprises a process for preparing the stable anatase nanometer TiO2 and nanometer tin-antimony oxide (ATO) slurry. After the transparent and insulating fluorocarbon coating is coated on the glass, the glass has good transparent and insulating effect (the light transmittance is 70-85% and the light transmittance of the sample glass is 91%), self-cleaning performance, washing resistance, good weather resistance and the like.

Description

technical field [0001] The invention relates to a transparent fluorocarbon coating with functions of heat insulation, self-cleaning, and weather resistance and its preparation process and application, in particular to a nano-antimony tin oxide (ATO) and anatase nano-titanium dioxide (TiO 2 ) Modified fluorocarbon coating and its preparation process and application. Background technique [0002] With the development of national economy and modern science and technology, people pay more and more attention to energy saving and environmental protection. Although ordinary glass has good transparency, it does not have enough insulation against infrared rays, which brings huge energy loss to many occasions that need to isolate heat radiation. In order to save energy, people have adopted products such as metal-coated heat-reflecting glass and various heat-reflecting films to reflect part of the energy in sunlight to achieve the purpose of heat insulation and cooling. However, some...
