Transparent heat-insulating film and its preparing process

The present invention relates to a transparent insulation film, particularly relates to a transparent insulation film composed of a transparent film substrate and a thermal barrier coating nanometer transparent, and can be widely applied to car windows, building windows and other occasions. Nano transparent insulation first functional coating, spray coating, and then the paint brush by way of a transparent film coated on the substrate surface, after drying and curing to obtain a transparent insulation film. The present invention was prepared using the method of nano transparent insulation film of a coating material, a preparation method is simple, low cost, to obtain a transparent insulation film, while having good transparency and excellent thermal insulation.
