Heat insulation UV-resistant thin film

Abstract

The invention discloses a heat insulation UV-resistant thin film, comprising a structural layer capable of absorbing heat of the sun and ultraviolet rays, wherein one side of the structural layer is provided with a splicing layer, the other side of the structural layer is provided with an anti-scratch wear-resistant layer, and the splicing layer and the anti-scratch wear-resistant layer are coextruded and laminated or coated onto the structural layer. The heat insulation UV-resistant thin film disclosed by the invention is adhered and fixed onto glass by virtue of the splicing layer, damage caused by glass fragments to personnel and objects at the periphery when the glass is fragmented can be avoided, and the heat insulation UV-resistant thin film has a good safety protection function; and scratch or damage of a common hard object to the surface of the thin film can be avoided by virtue of the anti-scratch wear-resisting layer.

Description

technical field [0001] The invention relates to a film material, in particular to a heat-insulating and anti-ultraviolet film. Background technique [0002] Energy conservation and emission reduction is one of the national strategies for implementing sustainable development, and it is also a major trend of international development. At present, there are more and more occasions where building glass, automotive glass and glass need to be used. Especially for buildings, the proportion of glass used is increasing. The energy saving and emission reduction of building glass has been widely concerned by countries all over the world. In my country, building energy consumption accounts for more than one-third of the country's total energy consumption, and the energy loss through building doors and windows accounts for more than 40% of the total building energy consumption. The energy-saving problem of building glass has become very prominent and urgent. urgent. However, for foreign...

Problems solved by technology

[0003] At present, for the thermal insulation of glass, the methods of sticking thermal insulation film and coating thermal insulation coating are mainly used. Among them, coating thermal insulation coating is affected by its own water washing resistance, scratch resistance, acid resistance, etc. Due to the influence of alkalinity, coating hardness and thermal insulation efficiency, its application range is greatly limited. Therefore, the method of bonding thermal insulation film to glass will become the main development direction in the future.

However, as far as the current preparation of thermal insulation film is concerned, it is mainly prepared by plating a multi-layer functional metal composite film layer on the plastic base film. The preparation process is complicated, the difficulty is high, and the cost remains high. The p
