Problems solved by technology

However, the plastic films commonly used in daily life often have some problems during use, such as low adhesion, difficulty in attaching to the surface of objects, and easy generation of air bubbles between the film and the plastic film. Another point is that it does not have the effect of flame retardancy. If once The consequences of sending a fire are very serious
If a fire breaks out during use, the non-flame retardant film will promote the spread of the fire, aggravate the fire, and make rescue more difficult

Abstract

The invention belongs to the technical field of decorative materials, and in particular relates to an electrostatic adsorption flame-retardant film. The electrostatic adsorption flame-retardant film includes a scratch-proof layer, a flame-retardant layer, a heat insulation base layer and a reflecting layer that are sequentially stacked from top to bottom. The scratch-proof layer is formed by coating and curing polyurethane resin added with nano-powder, the flame-retardant layer is formed by extruding and stretching a flame-retardant material and epoxy resin, the heat insulation base layer comprises polyethylene glycol terephthalate and polyvinyl chloride, and the reflecting layer is formed by coating polyimide and inorganic powder. The heat insulation base layer of the electrostatic adsorption flame-retardant film enables the film to generate an electrostatic effect, so that the film is easy to attach, uses a gum-free electrostatic technology, and can be used repeatedly. And the scratch-proof layer on the surface is made of an environment-friendly material, is waterproof, heatproof and oil-proof, is convenient to scrub, can increase the glass strength, and prevents the glass from being broken and splashing to hurt people. The flame-retardant layer can prevent the film from burning quickly, and the safety performance is improved. The reflecting layer can insulate heat and blocksun, realizes effective obstruction and protects privacy, and meanwhile reduces the indoor temperature.

Description

technical field [0001] The invention belongs to the technical field of decorative materials, in particular to an electrostatic adsorption flame-retardant film. Background technique [0002] Plastic film is one of the common daily necessities in our daily life. There are many types of plastic film, which can be classified according to the material, the way of use, and the shape. Because the plastic film can be set with different patterns, it is loved by many consumers, and the plastic film is usually used as a decoration. Used as a film on the glass or a table mat on the table. However, the plastic films commonly used in daily life often have some problems during use, such as low adhesion, difficulty in attaching to the surface of objects, and easy generation of air bubbles between the film and the plastic film. Another point is that it does not have the effect of flame retardancy. The consequences of sending a fire are very serious. If a fire breaks out during use, the no...
