Abstract

The present invention discloses a high pressure and crack resistant glass micro-bead for use in a reflection film and a method for preparing same. The glass micro-bead is prepared using the following raw materials based on part by weight: 24 to 38 parts of quartz powder, 14 to 26 parts of fluorite, 18 to 32 parts of zircon sand, 15 to 25 parts of corundum sand, 6 to 12 parts of :manganese dioxide, 5 to 10 parts of aluminum borate whisker, 16 to 28 parts of moissanite, 10 to 15 parts of nano barium sulfate, 12 to 24 parts of lazialite, 3 to 6 parts of tin dichloride, 4 to 8 parts of sodium carbonate, 3 to 5 parts of charcoal powder, and 5 to 8 parts of additive. According to the present invention, with addition of zircon sand and corundum sand, the pressure resistance strength of the glass micro-bead is improved, and with addition of aluminum borate whisker and nano barium sulfate, the anti-ageing and crack resistant properties of the glass micro-bead is improved. The glass micro-bead prepared according to the present invention has the characteristics of high pressure resistance and anti-cracking property, and is thus gains a broad application prospect in the reflection film.

Description

technical field [0001] The invention relates to a high-pressure-resistant and crack-resistant glass microsphere for a reflective film and a preparation method thereof, belonging to the field of glass microsphere manufacturing. Background technique [0002] Glass beads refer to solid or hollow glass beads with a diameter of several microns to hundreds of microns, which are divided into two types: colorless and colored. Those with a diameter of 0.8mm or more are called fine beads; those with a diameter of less than 0.8mm are called microbeads. Glass beads are a new type of silicate material, which are widely used because of their characteristics of transparency, adjustable refractive index, directional retroreflection, smooth surface, good fluidity, electrical insulation, stable chemical properties, heat resistance and high mechanical strength. Applied to reflective film. [0003] The reflective film is based on the principle of retro-reflective glass beads with high refrac...
