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 a glass microsphere for a TPU reflecting film and a preparation method of the glass microsphere. The glass microsphere is prepared from such raw materials in parts by weight: 25-35 parts of sepiolite, 36-49 parts of glass cullet, 22-38 parts of variscite, 16-27 parts of rutile, 22-36 parts of leucite, 30-40 parts of gold tailings, 5-10 parts of polymerized alpha-olefin, 3-6 parts of sorbitan olivate, 2-4 parts of dodecafluoropropyltrimethoxysilane, 3-6 parts of ethoxylated castor oil, 4-8 parts of 1,4-butanesultone and 8-14 parts of additives. Due to reasonable proportioning and scientific preparation process and technique, the production of high-quality, high-refractive index and high-stability of glass microspheres is realized; besides, the glass microspheres have good mechanical properties, corrosion resistance, weather resistance and high temperature resistance; furthermore, large-scale batch production can be realized.

Description

technical field [0001] The invention relates to a glass microsphere for a TPU 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. TPU reflective film is a novel reflective material formed by combining the reflective layer formed by glass beads and TPU polymer material by special technology. It is widely used in clothing, composite fabrics, sporting goods, inflatable products, and clothing accessories. , construction, shoe materials, printing, trademarks, water bags, handicrafts, etc. 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 i...
