Heat preservation and heat insulation double-layer glass cup

Abstract

A heat preservation and heat insulation double-layer glass cup comprises a cup body. The cup body is divided into an inner cup layer and an outer cup layer, a vacuum layer is arranged between the inner cup layer and the outer cup layer, the inner cup layer is made of a silicon dioxide material the same as the material of a common glass cup, and the outer cup layer is prepared from, by weight, 500 g of silicon dioxide, 1.2 g of pericarp extract of Sapindus mukorossi Gareth., 29 g of lapis lazuli, 6 g of tourmaline, 6.6 g of foam aluminum powder, 1.5 g of sea mud, 15.4 g of calcined kaolin, 5 g of modified starch, 4 g of selenium powder, 15 g of bamboo powder, 5 g of bone meal, 23.6 g of calcite, 0.5 g of zinc oxide, 1.3 g of potassium carbonate, 4.6 g of barium carbonate, 20 g of shells, 5 g of titanium carbide, 5 g of silicon carbide, 8 g of natural ocean stone, 8 g of hauynite, 5 g of pear-peel color clay, 8 g of magnesite, 8 g of potassium feldspar and 5 g of sepiolite. By changing the material of the outer cup layer, the prepared product is smooth in surface and good in heat insulation and heat preservation effect and does not scald the hands when used.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a thermal insulation double-layer glass. Background technique [0002] Glass is divided into non-oxide glass and oxide glass according to the composition, oxide glass is divided into silicate glass, borate glass, phosphate glass and so on. Silicate glass refers to the basic composition of Si0 2 Glass is a colorless and transparent material with the largest output, the widest range of uses, and the lowest price. Quartz glass is the best among silicate glasses. The raw materials used to manufacture quartz glass are crystal, high-purity quartz sand, or white quartz sand, and its composition is high-purity Si0 2 , the melting temperature is required to be above 1713°C. [0003] Quartz glass has a series of special physical and chemical properties: 1. It has excellent high temperature resistance, and its melting point is similar to that of platinum; 2. The thermal expansi...

Problems solved by technology

At present, the double-layer glasses appearing on the market are all made of quartz materials. Although they have a certain effect of heat preservation and heat insulation, the time of heat preservation needs to be improved.
