Abstract

The invention discloses a weather-resistant glass microsphere used for a reflective fabric and a preparation method thereof. The microsphere is prepared from the following raw materials by weight: 37 to 53 parts of wollastonite, 25 to 45 parts of quartz powder, 16 to 29 parts of chromite fines, 24 to 37 parts of scolecite, 16 to 25 parts of basalt, 20 to 35 parts of apatite, 14 to 22 parts of high-boron calcium borate, 15 to 25 parts of barium hydroxide, 9 to 18 parts of magnesium metaphosphate and 11 to 17 parts of an additive. According to the invention, the disadvantage of poor weather resistance of a conventional glass microsphere is overcome; the glass microsphere provided by the invention is endowed with excellent weather resistance and ageing resistance; meanwhile, the glass microsphere in the invention has high refractive index and compressive strength, so product performances are improved, and product service life is prolonged.

Description

technical field [0001] The invention relates to a weather-resistant glass bead for reflective cloth and a preparation method thereof, belonging to the field of glass bead manufacturing. Background technique [0002] Reflective cloth is made of high refractive index glass beads on the surface of the cloth base by coating or filming process, so that ordinary cloth can reflect light under the irradiation of light. It is mainly used for products related to road traffic safety. Widely used in reflective clothing, all kinds of professional clothing, work clothes, fashion, shoes and hats, gloves, backpacks, personal protective equipment, outdoor products, etc., and can also be made into various reflective products and accessories. Among them, glass beads are an important raw material for making reflective cloth, and the performance of glass beads directly affects the use effect of reflective cloth. At present, the quality and performance of glass microspheres produced by Chinese m...
