Problems solved by technology

Among them, glass microspheres are an important raw material for the manufacture of reflective films, but in actual production, due to the polar state of "hydrophilic and oleophobic" on the surface, the compatibility and affinity between them and the polymer matrix Poor, the obvious interface effect with the polymer matrix makes the glass beads agglomerate and other phenomena, which affects the performance of the reflective film and leads to a decline in quality

Abstract

The invention discloses a PET reflective membrane glass bead and a preparation method thereof. The glass bead is prepared by the following raw materials by weight: 56-72 of silicon powder, 38-56 of serpentine, 32-48 of hornblende, 16-28 of crystal broken stone, 27-41 of datolite, 42-64 of quartz sand, 15-25 of fluorine contained slag powder, 10-15 of diethylene glycol distearate, 8-14 of cyclohexene oxide, 5-7 of polypropylene glycol dipivalate, 4-6 of lauramidopropylamine oxide, and 12-16 of additives. Serpentine, hornblende, crystal broken stone, datolite, and fluorine contained slag powder are the main raw materials of the prepared glass bead, the effects of the raw materials are fully played, the performance of the produced glass bead is high, and the glass bead has excellent optical performance, mechanical properties, and heatproofing and aging properties, and is resistant to corrosion.

Description

technical field [0001] The invention relates to a glass microsphere for a PET type reflective film and a preparation method thereof, belonging to the field of glass microsphere manufacture. Background technique [0002] Reflective film is a film with a special structure that uses optical principles to retroreflect light back to the light source. PET reflective film is a new high-performance composite reflective material formed by combining the reflective layer formed by glass beads and PET polymer materials by a special process. It is widely used in billboards with reflective requirements, traffic reflective Signs (reflective road signs, reflective isolation belts, reflective car number plates), reflective police uniforms, industrial safety signs, etc. Among them, glass microspheres are an important raw material for the manufacture of reflective films, but in actual production, due to the polar state of "hydrophilic and oleophobic" on the surface, the compatibility and affi...
