Abstract

The invention discloses fireproof glass micro-beads for flame-retardant reflective cloth and a preparation method thereof. The fireproof glass micro-beads are prepared from the following raw materials in parts by weight: 42-59 parts of andalusite, 33-46 parts of volcanic rock, 27-39 parts of eclogite, 36-52 parts of baddeleyite, 29-44 parts of sellaite, 5-10 parts of sodium tungstate, 6-12 parts of yttrium aluminate, 10-15 parts of white clay, 16-24 parts of bauxite, 26-37 parts of flint clay, and 12-14 parts of an additive. The prepared glass micro-beads have high the refractoriness which is as high as more than or equal to 1700 DEG C, also have the advantages of good weather resistance, high compressive strength, good corrosion resistance, good flexibility, and high refractive index, and can improve high temperature resistance and fire prevention performance while ensuring light reflective performance of the flame-retardant reflective cloth.

Description

technical field [0001] The invention relates to a fire-resistant glass bead for flame-retardant 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...
