Abstract

The invention discloses a preparation method of foam glass, relating to the technical field of building materials. The preparation method adopts the following raw materials in parts by weight: cathode-ray tube, pearlite, calcium carbonate, mirabilite, foaming accelerant, foam stabilizer and borax. The preparation method comprises the following steps: A, separating a glass shell of the cathode-ray tube; B, mixing the glass shell, the perlite, the calcium carbonate, the mirabilite and the borax to obtain a mixture, and grinding the mixture in a ball mill to obtain powder; C, filtering the powder by virtue of a screen; D, uniformly mixing the powder, the foaming accelerant and the foam stabilizer, and placing the mixture into a mold; E, placing the mold into a kiln, and preheating; F, after the preheating is ended, heating the kiln; and G, annealing the kiln, and taking out the mold after the annealing. Compared with the prior art, the problem of environmental pollution caused by the abandoned waste cathode-ray tube can be solved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing foam glass used for building walls. Background technique [0002] Foam glass is generally an inorganic non-metallic material made of crushed glass, foaming agent, modified additives, finely crushed and uniformly mixed, then melted at high temperature, foamed, and annealed. The cathode ray tube is the main display device of the display, including electron guns, deflection coils, shadow masks, phosphor layers and glass casings. my country is a large producer and waste country of televisions and other displays, and a large amount of barium oxide containing heavy metals is produced every year. , strontium oxide, and lead oxide cathode ray tube glass casings are discarded, causing environmental pollution. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for preparing foam glass, wh...
