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 PVC type reflective film and a preparation method thereof. The glass microspheres for a PVC type reflective film are prepared by using the following raw materials in parts by weight: 33-47 parts of titanite, 22-36 parts of wollastonite, 18-29 parts of shale, 24-38 parts of diopside, 32-46 parts of ulexite, 16-28 parts of attapulgite, 15-25 parts of blast furnace water granulated slag, 6-12 parts of tall oil fatty acid, 5-10 parts of triolein, 3-6 parts of coconut oil amine polyoxyethylene ether, 2-4 parts of pentaerythritol monolaurate, 2-3 parts of octyldodecyl beeswax ester, and 9-14 parts of an additive. The glass microspheres prepared by using the method are excellent in performance, stable in quality and high in rounding rate, which may be over 95%, the index of refraction can reach 1.95-2.15; in addition, the glass microspheres have higher compressive strength, better chemical stability, corrosion resistance and aging resistance, and have broad application prospects.
Description
technical field [0001] The invention relates to a glass microsphere for a PVC 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. PVC reflective film is a new high-performance composite reflective material formed by combining the reflective layer formed by glass beads and PVC polymer materials by a special process. It is widely used in clothing, shoes and hats, gloves, bags, Raincoats, car bodies and other daily necessities and work supplies. 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 ma...
