Abstract

The invention relates to a preparation method of self-preparing multifunctional glass, in particular to a preparation method of self-repairing multifunctional glass. The preparation method comprises the following steps: (1) surface treatment of a glass base layer; (2) annealing treatment; (3) preparation of the self-repairing glass; and (4) carrying out surface coating to obtain the self-repairingmultifunctional glass. The preparation method of the self-preparing multifunctional glass has the beneficial effects that (1) after the glass is broken, the broken glass cannot drop; (2) a glass adhesive cannot be cured in advance, and thus, the glass can be repaired in time after being broken; and (3) the self-repairing multifunctional glass is diversified in function and can be used under various conditions.

Description

technical field [0001] The invention relates to a method for preparing glass, in particular to a method for preparing self-repairing multifunctional glass. Background technique [0002] Glass is an amorphous inorganic non-metallic material, generally made of various inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) of. Its main components are silicon dioxide and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O•CaO•6SiO2, etc. The main component is silicate double salt, which is an amorphous solid with an irregular structure. Widely used in buildings, used for wind and light transmission, belongs to the mixture. Glass is usually hard and brittle, and it tends to shatter when it is hit, thereby threatening the safety of the user, and it cannot be repaired after being shattered, but can only be replaced, thereby increasing the cost of use. [0003] Self-repairin...
