Purple red colorant for low-temperature colored glass and preparation method and using method thereof

Abstract

The invention belongs to the field of colored glass, and particularly relates to a purple red colorant for low-temperature colored glass and a preparation method and a using method thereof. The purplered colorant comprises the following raw materials in parts by mass: 30-50 parts of quartz powder, 10-30 parts of borax, 10-25 parts of sodium carbonate and 10-30 parts of a coloring additive, wherein the coloring additive is one or a mixture of several of manganese monoxide, manganese dioxide, manganese trioxide and potassium permanganate. The purple red colorant is prepared by mixing the materials, melting at high temperature, performing water quenching, drying, and crushing. Through use of a large amount of silicon oxide, the borax and the sodium carbonate with low melting points in a colorant base material, the diffusion rate of a colorant in 1200 DEG C glass liquid is greatly increased, so that a uniform colored glass stock solution is formed; in a preparation technology of the colorant, composite powder is directly added into a high-temperature frit furnace for melting, and the reaction temperature is instantly raised from room temperature to 1350-1500 DEG C, so that decomposition, volatilization and composition segregation of the materials in a slow heating process are prevented, and a colorant product with a high stoichiometric ratio and high high-temperature diffusion rate is obtained.

Description

technical field [0001] The invention belongs to the field of colored glass, and in particular relates to a purple-red colorant for low-temperature colored glass and a preparation method and application method thereof. Background technique [0002] Colored glass refers to glass that can absorb, reflect, and pass through light of different wavelengths to present different colors. Colored glass has purple, brown, purple, green, golden and other colors, and has many functions, such as effectively absorbing the sun's radiant heat, producing "cold room effect", achieving the effect of heat shielding and energy saving; The sunlight becomes soft and avoids glare; it can effectively absorb the ultraviolet rays of the sun's rays and prevent indoor items from fading and deterioration, etc. [0003] At present, the color glass preparation process is to directly add the glass colorant to the glass melting furnace at about 1600 ℃. The temperature of the furnace is high, so that the color...
