Abstract

The invention discloses a thermos bottle blank material with a high thermal stability. The thermos bottle blank material comprises, by weight, 50-60 parts of silica powder, 5-7 parts of clay, 2-3 parts of salt, 2-3 parts of sodium fluoride, 7-9 parts of calcium carbonate, 1-2 parts of lithium oxide, 10-15 parts of sodium carbonate, 0.5-1 part of ammonium biphosphate, 1-2 parts of magnesium chloride, 3-4 parts of calcium fluoride, 4-6 parts of alumina, 2-3 parts of a thermal stabilizer and 1-2 parts of a compound clarifier aid. The thermal stabilizer added in the invention well compounds gadolinium oxide with lanthanum oxide to realize a better thermal stability effect; lithionite can improve the fluidity and the adhesive force of vitreous force and reduce the thermal expansion coefficient of products; and barium oxide and sodium tellurate can improve the thermal stability of the glass.

Description

technical field [0001] The invention mainly relates to a thermos bottle preform material with high thermal stability, which belongs to the field of glass materials. Background technique [0002] The traditional thermos bottle preform is made of silicon dioxide as the main material and mixed with several oxides. The mechanical strength is not high, which makes it easier to break during use and transportation, resulting in waste of resources. Some thermal stability Not strong, unable to adapt to the boiling water environment for a long time, not only easy to break, but also may damage personal safety. Contents of the invention [0003] The object of the present invention is to provide a thermos bottle preform material with high thermal stability. [0004] The present invention is achieved through the following technical solutions: [0005] A thermos bottle preform material with high heat stability, which is composed of the following raw materials in parts by weight: [00...
