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 glass microspheres for a micro-prismatic reflective film, and a preparation method thereof. The glass microspheres are prepared from the raw materials of, by weight, 32-46 parts of river sand, 23-37 parts of kaolin, 16-28 parts of wavellite, 30-40 parts of datolite, 15-25 parts of calcium hydroxide, 20-30 parts of silica, 10-15 parts of titania, 12-23 parts of hornblende, 4-6 parts of dodecyl dihydroxyethyl betaine, 5-8 parts of sodium tall oil pitch sulfonate, 3-5 parts of dodecyl dimethylbenzyl ammonium chloride, 4.5-6.5 parts of fatty alcohol polyether amide, and 5-10 parts of an additive. The glass microspheres provided by the invention have high brightness, good mechanical performances, excellent weatherability, excellent corrosion resistance, excellent heat resistance and excellent durability. The glass microspheres are durable, and can be widely applied in micro-prismatic reflective films. The glass microspheres have a good market prospect.

Description

technical field [0001] The invention relates to a glass microsphere for a microprism type reflective film and a preparation method thereof, belonging to the field of glass microsphere manufacture. Background technique [0002] Reflective film is a novel reflective material formed by combining the reflective layer formed by glass beads with polymer materials such as PVC, PU, ​​PET, acrylic, and PC by using a special process. The reflective principle of the micro-prism reflective film is based on the fact that light is incident from a certain angle in three-dimensional space, reflected three times on three mutually perpendicular planes, and then reflected back along the original incident direction. 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 obviou...
