Abstract

The invention provides a hot melt adhesive for a reflective film. The hot melt adhesive comprises the following raw materials in parts by mass: 45-50 parts of saturated polyester resin, 27-32 parts ofa solvent, 0.3-0.7 part of a dispersing agent, 12.5-13 parts of 1,6-hexanediol diacrylate, 0.2-0.4 part of an anti-oxidation auxiliary agent, 0.8-1.2 parts of an ultraviolet absorbent and 5-6 parts of glass beads. The invention also provides a preparation method of the hot melt adhesive for the reflective film, the reflective film and a preparation method of the reflective film. The retro-reflection coefficient of the reflective film can be enhanced, so that the reflective film is suitable for more occasions.

Description

technical field [0001] The invention relates to a hot-melt adhesive used for a reflective film, a reflective film and a manufacturing method thereof. Background technique [0002] The reflective film can reflect most of the incident light back along the direction of the emitting light source, and is widely used in a variety of products, such as road signs, obstacles blocking access, truck body identification, etc., with its bright colors during the day. Obvious warning function, at night or under low light conditions, its bright reflective effect can effectively enhance people's recognition ability. However, the retroreflection coefficient of the existing microprism reflective film is not strong enough, which limits its applicable occasions. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art, and propose a hot melt adhesive for reflective film, reflective film and its manufacturing method, which can enha...
