Embodiment

[0015] Take the following raw materials (kg): sea sand 80, limestone 20, wollastonite 12, magnesite 10, burnt gem 18, red mud 7, broken glass 25, fluorite 10, borax 5, calcium phosphate 4 , Glauber's salt 3.5, mica powder 4.5, graphene 5.

[0016] The preparation method of the heat-shock-resistant glass for the liner of the thermos bottle comprises the following steps:

[0017] (1) Mix sea sand, limestone, wollastonite, and magnesite evenly, crush them, pass through a 80-mesh sieve, wet ball mill for 24 hours, and dry at 110°C. After the water is dried, mix the mixture at 250°C Raise the temperature from room temperature to 860°C at a rate of 200°C / h for 1 hour, then raise the temperature to 1220°C at a rate of 200°C / h, take it out after calcination for 2 hours, quench it into granules, and dry to obtain granular glass frit;

[0018] (2) Mix burnt gems, red mud, broken glass, and fluorite evenly, crush them, pass through a 1000-mesh sieve, mix evenly with borax, calcium phosp...

Abstract

The invention discloses thermal shock-resistant glass for a vacuum bottle liner and a preparation method thereof. The thermal shock-resistant glass is prepared from the following raw materials, by weight, 75-85 parts of sea sand, 15-25 parts of limestone, 10-15 parts of wollastonite, 10-15 parts of magnesite, 15-20 parts of flint clay, 5-10 parts of red mud, 20-30 parts of cullet, 8-12 parts of fluorite, 4-6 parts of borax, 3-5 parts of calcium phosphate, 2.5-4.5 parts of saltcake, 3.5-5.5 parts of mica powder and 3-6 parts of graphene. The thermal shock-resistant glass provided by the invention has low thermal expansion coefficient, good heat stability and excellent thermal shock resistance. By the use of the thermal shock-resistant glass, rupture caused by thermal shock is avoided, and service life of a vacuum bottle is prolonged.

Description

technical field [0001] The invention relates to a glass and a preparation method thereof, in particular to a heat-shock-resistant glass for a thermos bottle liner and a preparation method thereof. Background technique [0002] The thermos bottle is a kind of daily necessities with a wide range of uses. It can be used to store hot water, hold cold drinks and medicines. The thermos bottle is composed of an inner tank, an outer shell and additional parts. Made of double-layer glass, the two sides of the interlayer are plated with silver and other metals, the middle is evacuated, and the bottle mouth has a stopper, which can maintain the temperature in the bottle for a long time. However, under the impact of boiling water, the inner liner of the thermos bottle on the existing market produces a larger instantaneous thermal stress on the mouth bottle and the bottle body, which causes the liner to break and limits the service life of the thermos bottle. Contents of the invention ...
