High-strength heat-resistant glass micro-bead for reflective film and preparation method thereof

Abstract

The invention discloses a high-strength heat-resistant glass micro-bead for a reflective film and a preparation method thereof. The high-strength heat-resistant glass micro-bead for the reflective film is prepared by using the following raw materials in parts by weight: 38 to 49 parts of quartz powder, 24 to 37 parts of staurolite, 17 to 33 parts of phenacite, 22 to 34 parts of fluorite, 9 to 17 parts of carbon nano-tube, 12 to 18 parts of hafnium boride, 10 to 15 parts of lead silicate, 24 to 36 parts of steel slag micro-powder, 20 to 30 parts of kyanite tailing, 8 to 14 parts of potassium pyrosulfate, 5 to 10 parts of sodium carbonate, 10 to 15 parts of cerium carbonate and 6 to 12 parts of additive. By using staurolite, phenacite, steel slag micro-powder, kyanite tailing and the like as main raw materials, the advantages of each component are fully exploited and the high temperature resistance of the glass micro-bead can be obviously improved; by adding carbon nano-tube, hafnium boride, lead silicate and cerium carbonate, the thermal stability and the high temperature resistance of the glass micro-bead can also be improved, and the glass micro-bead is enabled to still have higher mechanical strength and better optical performance under high temperature conditions, and the glass micro-bead prepared by the invention has higher mechanical strength and a better reflective effect, can resist high temperature of 1380 DEG C and is applicable to part of reflective film production which has higher requirements on temperature.

Description

Technical field [0001] The present invention involves a high -strength heat -resistant glass micro -beaded and preparation method, which belongs to the field of glass micro beads. Background technique [0002] Glass micro beads refers to the solid or hollow glass beads with a diameter of several hundred 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 0.8mm are called micro beads.Glass micro -beads are a new type of silicate material. Due to the characteristics of transparent, refractive index, targeted return reflection, smooth surface, good liquidity, electrical insulation, stable chemical performance, high heat resistance, and high mechanical strength, they are widely widespread.Apply to the reflective film. [0003] The reflective film is the principle of reflection of glass micro beads with high refractive index. It can reflect the direct light reflec...

Problems solved by technology

At present, the quality and performance of glass microspheres produced by Chinese manufacturers are unstable, and there are still shortcomings such as low mechanical strength and poor heat resistance, and there is still a certain gap compared with foreign glass microspheres.
