Glass and preparation method thereof

Abstract

The invention relates to the technical field of glass, in particular to glass and a preparation method thereof. The invention discloses glass, which is prepared from the following raw materials in parts by mass: 70 to 80 parts of water, 4 to 5 parts of emulsifier, 2 to 3 parts of n-butyl acrylate, 6 to 7 parts of polymethylhydrosiloxane, 11 to 12 parts of polydimethylsiloxane, 14 to 15 parts of acrylic acid, 10 to 11 parts of polymethacrylate, 1 to 2 parts of tert-butyl hydroperoxide, 25 to 30 parts of polyurethane resin and 4 to 5 parts of lithium sulfate. The invention has the beneficial effects that when a glass body is polished, it can be guaranteed that the glass body cannot move in the polishing process, the polishing quality is guaranteed, meanwhile, an air pump is started, air exhaust operation is conducted on a supporting pipe, therefore, suction force exists on the glass body at the position of a through hole, the limiting effect is better, and in addition, the corners of the glass body can be continuously polished through one polishing head, the whole polishing operation is completed, the polishing efficiency is higher, polishing is more uniform and smoother, and the polishing quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to glass and a preparation method thereof. Background technique [0002] Tempered glass is a kind of glass, which belongs to safety glass. It is a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used. Physical tempered glass is also called quenched tempered glass. It heats ordinary flat glass in a heating furnace to tempering temperature, that is, when it is close to the softening temperature of the glass, eliminates the internal stress through its own deformation, then moves the glass out of the heating furnace, and then blows high-pressure cold air to the glass with a multi-head nozzle. Tempered glass can be produced by quickly and evenly cooling to room temperature, and compressive stress is formed on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby imp...

Problems solved by technology

[0005] Aiming at the technical problems existing in the prior art, the present invention provides a glass and its preparation method to solve the problem of cutting, edging, washing, drying and tempering when the existing toughened glass is prepared. It is necessary to use an edging device to grind the edges. Usually, after the edge is finished, the corners must be rounded, which makes the grinding efficiency low. Flat, making it easy to burst during tempering, and, when grinding, the glass cannot be stably limited, thus affecting the quality of grinding
