Abstract

The invention discloses a fluoride-free environment-friendly thermos bottle preform material. The fluoride-free environment-friendly thermos bottle preform material consists of the following raw materials in parts by weight: 40-45 parts of quartz sands, 10-15 parts of calcite, 6-10 parts of lepidolite, 4-6 parts of aluminum phosphate, 5-7 parts of colemanite, 1-2 parts of antimonous oxide, 3-5 parts of calcium chloride, 0.1-0.2 part of lanthanum oxide, 2-3 parts of sodium sulfate, 5-7 parts of aluminum oxide, 0.8-2 parts of ammonium dihydrogen phosphate, 0.1-0.2 part of stannous oxide, 2-4 parts of fluxing agent and 3-5 parts of molding promoter. The fluoride-free environment-friendly thermos bottle preform material disclosed by the invention almost realizes no fluoride residue, and is healthy and environment-friendly; the added molding promoter lowers a thermal expansion coefficient of glass, and enables the obtained finished product to have higher hardness and mechanical strength after various raw materials are molded, so that spoilage of a preform is reduced, waste is reduced and resources are saved.

Description

technical field

[0001] The invention mainly relates to a fluorine-free environmental protection thermos bottle preform material, 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 fluorine-free environmental protection thermos bottle preform material.

[0004] The present invention is achieved through the following technical solutions:

[0005] A fluorine-free environmental protection thermos bottle preform material, which is composed of the follow...
