Abstract

The invention provides a TOM film suitable for automobile exterior decoration and a preparation method of the TOM film. The TOM film suitable for the automobile exterior decoration comprises a surface protection layer, a decoration layer, a bonding layer, a substrate and a back glue layer which are sequentially arranged from top to bottom. The invention also provides a preparation method of the TOM film. According to the TOM film suitable for the automobile exterior decoration, the decoration requirement of the automobile exterior decoration is met, and meanwhile, the surface protection layer is made of the PVDF / PMMA co-extrusion film material with more excellent comprehensive performance, so that the TOM film can bear the harsh automobile exterior decoration use environment.

Description

technical field [0001] The invention relates to a film and a preparation method thereof, in particular to a TOM film suitable for automobile exterior decoration and a preparation method thereof, belonging to the technical field of film materials. Background technique [0002] TOM technology, which belongs to the category of out-of-mold decoration, is the abbreviation of three-dimensional vacuum forming surface decoration technology. The principle of TOM process molding: the equipment is divided into upper and lower boxes, which are divided into two independent sealed spaces through the pre-prepared film; the upper and lower boxes are evacuated by the vacuum pump at the same time, and the upper box starts to heat when the vacuum reaches a certain level. The diaphragm is softened, and when the set temperature is reached, the workbench is lifted up and the air pressure is released from the upper box at the same time, and the softened diaphragm is bonded to the surface of the wo...
