Abstract

The invention provides a heat-resistant decorative film and a preparation method thereof, and belongs to the technical field of decorative film. The heat-resistant decorative film includes a PVC filmlayer, a base cloth layer and a heat-resistant layer; the base cloth layer is a warp knitted fabric; the PVC film layer includes the following components in parts by weight: PVC resin, polypropylene fibers, diphenyl isooctyl phosphite, a stabilizer, a light shading powder, a flame retardant filling material, polypropylene fibers, and glass fibers; the heat-resistant layer includes the following components in parts by weight: waterborne silicone acrylic resin, amino resin, sodium bicarbonate, polyethylene wax, nano titanium dioxide, a waterborne polyisocyanate curing agent, magnesium stearate,polyoxypropylene glycerol ether, carboxymethyl cellulose, ammonium polyphosphate, and ceramic fibers. The prepared decorative film has good heat resistance.

Description

technical field [0001] The invention belongs to the technical field of decorative films, and relates to a heat-resistant decorative film, in particular to a heat-resistant decorative film and a preparation method thereof. Background technique [0002] With the development of society, a large number of plastic parts are used in household appliances, automobiles, mobile phones and other components, and the requirements for surface decoration are getting higher and higher. Decorative film has been widely used in outdoor aluminum alloy doors and windows in Germany, Japan, South Korea and other countries as a laminated decorative film. Since the 21st century, decorative film has been introduced into my country. The decorative film traditionally manufactured in my country is made of PVC material. There are relatively unstable and active Cl- in the molecular structure of PVC, which is easy to form a double bond structure, which makes the weather resistance of PVC resin worse, and i...
