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 industrial safety signs

Abstract

The invention discloses a glass bead for an industrial safety identification reflective film and a preparation method thereof. The glass bead is prepared from the following raw materials by weight: 36-49kg of perlite tailings, 24-37kg of kyanite, 14-26kg of magnesite, 28-42kg of sillimanite, 42-58kg of quartz sand, 25-38kg of ceramic waste, 23-36kg of cullet, 6-9kg of PEG methyl glucose dioleate, 8-12kg of poly(sodium-p-styrenesulfonate), 4-8kg of poly(oxy-1,2-ethanediyl), 3-6kg of sorbitan monolaurate, and 11-16kg of additives. The glass bead is high in refractive index and good in reflection effect, has excellent high temperature resistance property, chemical stability, weatherability, and comprehensive properties, and can be widely applied to industrial safety identification reflective films.

Description

technical field [0001] The invention relates to a glass bead used for reflective films of industrial safety signs 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 f...
