Abstract

The invention relates to a preparation method for foam glass with high compressive strength, belonging to the technical field of building materials. The foam glass comprises the following raw materials by weight: 90-94% of waste glass abrasive powder, 1.00-1.50% of a raw material additive, 0.5-2.0% of sodium hexametaphosphate, 1.0-3.0% of borax, 0.4-0.8% of thenardite, 1.5-4% of calcium carbonate, 1.8-1.9% of a foaming agent, 0.6-0.8% of a foam stabilizer, 0.2-0.4% of a flux and 0.1-0.2% of a reinforcing agent. The preparation method comprises the following steps: sufficient grinding in a conical ball mill; and melting, foaming and cooling in an electromagnetic induction heater. The foam glass prepared by using the method has high compressive strength, uniform stomatal structure, small density and low thermal conductivity.

Description

technical field [0001] The invention belongs to the technical field of building materials and relates to a method for preparing foam glass with high compressive strength. Background technique [0002] Foam glass is a new type of green and environmentally friendly inorganic non-metallic building material made of waste glass. It can be used to make wall bricks, roof tiles, etc. It not only realizes the recycling of garbage, but also has heat insulation, moisture resistance, sound absorption, and long service life. And other advantages, gradually be promoted in the construction industry. [0003] Publication No. CN106904837A (Application No. 201710177698.8) "A Production Method for Preparing Foamed Glass" refers to the preparation of foamed glass by putting the raw materials into a self-consolidating mixer for stirring to configure the melt, and then foaming in the foaming chamber. Pressed by a calender and annealed. Publication No. CN 106892566 A (Application No. 20171017874...
