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 an acrylic resin type reflective film and a preparation method thereof. The glass microspheres for an acrylic resin type reflective film are prepared by using the following raw materials in parts by weight: 38-54 parts of yellow sand, 23-37 parts of idocrase, 18-34 parts of albite, 20-35 parts of rhyolite, 14-27 parts of boracite, 12-18 parts of barium carbonate, 10-15 parts of strontium carbonate, 4-8 parts of lanthanum nitrate, 4-7 parts of diethylenetriamine, 3-4 parts of ethoxylated aminopropyl polydimethylsiloxane, 5-8 parts of dioctadecyl dimethyl ammonium chloride and 11-14 parts of an additive. The glass microspheres for an acrylic resin type reflective film are prepared by using the raw materials such as yellow sand, idocrase, albite, rhyolite and boracite, are greater than or equal to 1.93 in index of refraction and good in product quality and reflective properties, and have the advantages of excellent flexibility, weatherability, heat resistance and the like.

Description

technical field [0001] The invention relates to a glass microsphere for an acrylic resin 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. Acrylic resin reflective film is a novel reflective material formed by combining the reflective layer formed by glass beads and acrylic resin polymer materials by a special process. It is widely used in guiding signs, prohibition signs, warning signs and Directive signs and signs used for general advertising. 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...
