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 high water-resistant glass microspheres for a reflective film and a preparation method thereof. The high water-resistant glass microspheres for a 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 prepared by using the method not only have a good reflective effect and have the index of refraction over 2.05, but also have the advantages of excellent high temperature resistance, corrosion resistance, water resistance, and aging resistance, and have a wide application scope and a long service life.

Description

technical field [0001] The invention relates to a high water-resistant glass bead for a reflective film and a preparation method thereof, belonging to the field of glass bead manufacturing. Background technique [0002] Reflective film is a film with a special structure that uses optical principles to retroreflect light back to the light source. 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. 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 le...
