Problems solved by technology

[0002] The traditional thermos bottle preform is made of silica 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

Abstract

The invention discloses a rare-earth-contained thermos flask blank material composed of the following raw materials in parts by weight: 70-80 parts of silicon powder, 20-30 parts of dolomite, 10-15 parts of potash feldspar, 4-6 parts of magnesium oxide, 2-3 parts of calcium oxide, 3-4 parts of zirconium dioxide, 1-2 parts of aluminum oxide, 0.08-0.1 part of lanthanum carbonate, 0.5-1 part of boric oxide, 10-20 parts of premix and 1-2 parts of composite clarification aid. The premix added in the rare-earth-contained thermos flask blank material is added into main molten glass after being clarified in advance, so that the air bubble environment in the molten glass is improved, and the clarification effect is effectively promoted; the premix is also favorable in shock resistance and fusion assistance performance and capable of reducing the product sintering temperature, shortening the sintering time and improving the flowability and adhesive force.

Description

technical field [0001] The invention mainly relates to a thermos bottle preform material containing rare earth, 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 purpose of the present invention is to provide a thermos bottle preform material containing rare earth. [0004] The present invention is achieved through the following technical solutions: [0005] A rare earth-containing thermos bottle preform material, which is composed of the following raw materials in parts by weight: [0006] Si...
