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. In addition, the existing glass beads on the market still have the disadvantage of poor overall performance , unable to meet the requirements for the use of reflective film for road signs

Abstract

The invention discloses a glass bead for guide post reflective film and a preparation method thereof. The glass bead is prepared from the following raw materials by weight: 35-55kg of quartz sand, 21-39kg of pyrophillite, 14-27kg of aventurin, 17-33kg of pandermite, 15-25kg of manganese slag, 12-18kg of zirconium silicate, 10-15kg of crystalline graphite powder, 4-6kg of cerium oxide, 20-30kg of kyanite, 5-7kg of cocamidopropylamine oxide, 4-6kg of triethanolamine N-Coco acy-L-Glutamate, 6-8kg of sodium dodecyl benzene sulfonate, and 6-12kg of additives. The glass bead has excellent comprehensive properties, corrosion resistance property, light aging resistance property, and heat resistance property, and is high in refractive index and compressive strength, and moreover, the guide post reflective film prepared by the glass bead is high in reverse reflection coefficient, good in reflection effect, good in weatherability, durable in use, and good in market prospect.

Description

technical field [0001] The invention relates to a glass microsphere used for a reflective film of a road sign 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. 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 ...
