A kind of tempered glass and its manufacturing process

Abstract

The invention belongs to the technical field of materials and particularly discloses tempered glass and a manufacturing process thereof. The tempered glass comprises a tempered glass substrate and an explosion-proof layer. The tempered glass substrate comprises, by weight, 20-60 parts of silicon dioxide, 10-15 parts of limestone, 3-5 parts of borax, 5-8 parts of calcium carbonate, 10-16 parts of feldspar, 3-8 parts of bauxite, 5-13 parts of calcium silicate, 2-5 parts of sodium oxide, 2-4 parts of lithium oxide, 4-8 parts of bismuth oxide, 7-9 parts of aluminium sesquioxide, 1.5-2.5 parts of macrogol ester, 3-7 parts of copper sulfate pentahydrate, 5-11 parts of potassium permanganate, 3-6 parts of sodium hydroxide and 2-6 parts of a clarifying agent; the explosion-proof layer is composed of, by weight, 15-30 parts of polyvinyl alcohol, 30-60 parts of butyraldehyde, 15-30 parts of hydrochloric acid, 8-12 parts of plasticizer and 6-9 parts of an additive. According to the tempered glass and the manufacturing process thereof, a PVB middle membrane is additionally arranged between two layers of tempered glass, good binding power is achieved for inorganic glass, possibility of spontaneous explosion of the tempered glass can be effectively reduced, and the performance of the prepared tempered glass is far superior to conventional tempered glass.

Description

technical field [0001] The invention belongs to the technical field of materials, and specifically relates to a tempered glass and a manufacturing process thereof. Background technique [0002] Tempered glass is safety glass. Compared with ordinary glass, tempered glass has higher safety, thermal stability and higher strength. With the promotion and popularization of tempered glass technology, tempered glass has been widely used in automobile, construction, aviation, electronics and other fields. Although the strength of tempered glass is stronger than that of ordinary glass, due to the unstable composition of tempered glass, with the increase of use time, there is the possibility of self-explosion (self-breaking). SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the present invention provides a tempered glass and a manufacturing process thereof. In order to achieve the purpose of reducing the self-explosion of tempered glass. [0004] ...

AI Technical Summary

Problems solved by technology

Although the strength of tempered glass is stronger than that of ordinary glass, due to the unstable composition of tempered glass, there is a possibility of self-explosion (broken by itself) as the time of use increases.
