Preparation method for smoky yellow crystal bead blanks

Abstract

The invention discloses a preparation method for smoky yellow crystal bead blanks. The preparation method for smoky yellow crystal bead blanks aims to overcome shortcomings that existing preparation process for smoky yellow crystal bead blanks needs lead oxide as a raw material, coloring and optical properties of iron ions are poor, coloring property of manganese is unstable, and rhinestone bead blanks are poor in physical and chemical properties. Raw materials of the preparation method do not contain lead oxide, and the crystal bead blanks are good in physical and chemical properties, are proper in hardness and high in corrosion resistance. In the preparation method for the smoky yellow crystal bead blanks, raw materials of the smoky yellow crystal bead blanks include, by weight ratio, from 50 to 65 parts of quartz sand, from 2 to 20 parts of titanium dioxide, from 2 to 10 parts of sodium carbonate, from 7 to 20 parts of potassium carbonate, from 0.3 to 5 parts of potassium nitride, from 0.1 to 5 parts of cerium oxide, equal to or lower than 6 parts of boric acid, equal to or lower than 2 parts of aluminum hydroxide, equal to or lower than 8 parts of zinc oxide, equal to or lower than 10 parts of magnesium carbonate, equal to or lower than 15 parts of barium carbonate, equal to or lower than 2 parts of lithium carbonate, equal to or lower than 2 parts of potassium permanganate, equal to or lower than 4 parts of sodium nitrate and equal to or lower than 3 parts of iron oxide red.

Description

technical field [0001] The invention relates to the field of artificial crystal products, in particular to a method for preparing smoky yellow crystal bead embryos. Background technique [0002] Smokey yellow crystal bead embryos are semi-finished products used to prepare smokey yellow crystal products, and there are following deficiencies in the existing technology for preparing smokey yellow crystal bead embryos: [0003] 1. In order to achieve a higher refractive index, lead oxide must be used as the raw material. It is well known that lead-containing substances will cause environmental pollution; [0004] 2. The physical and chemical properties of crystal bead embryos are not good, the hardness is either too high or too low, and the corrosion resistance is poor; [0005] 3. In the preparation process, iron ions are used for coloring, which has poor product performance, unsatisfactory color light and poor effect, and the iron content of the raw material quartz sand is re...

Problems solved by technology

[0007] The purpose of the present invention is aimed at the above-mentioned raw materials that exist in the preparation of smoky yellow crystal bead embryos. Lead oxide is used in the raw materials. Due to the disadvantages of poor optical properties of iron ion coloring and unstable manganese coloring, it provides a smoke yellow color with no lead oxide in the raw material, good physical and chemical properties, moderate hardness, and strong corrosion resistance.
