Abstract

The invention provides green ecological foam glass prepared from the following raw materials in parts by weight: 75-80 parts of waste glass powder, 15-20 parts of shell powder and 0-5 parts of coal ash. The green ecological foam glass is produced by using a production method comprising the steps of 1, respectively crushing and grinding waste beer bottles and shells, and controlling the fineness, namely the screen residue of a 0.08mm square hole sieve, to be lower than 10%; 2, uniformly mixing the waste glass powder, the shell powder and the coal ash, placing the mixture into a mould in which alundum powder serving as a separant, calcining at 800-850 DEG C in a high-temperature furnace, preserving the heat for 0.8-1.2 hours, and annealing at the temperature of 500-600 DEG C; and 3, cooling the high-temperature furnace to 180-220 DEG C, taking out the mould, and demolding to obtain the green ecological foam glass. The foam glass produced by using the waste glass, shells serving as renewable resources and the coal ash has the advantages of high adsorptivity, bacterium inhibition, nontoxicity, no combustibility, small heat conductivity coefficient and energy saving so as to be a novel green ecological heat insulation material.

Description

technical field [0001] The invention belongs to the new technology of using waste to produce building materials, and in particular relates to a formula and preparation method of foam glass. Background technique [0002] Foam glass is a porous inorganic thermal insulation material obtained by stirring and mixing glass powder and foaming agent, molding and calcining. Commonly used foaming agents are limestone, calcium carbide, etc. Limestone has a high foaming temperature of 850°C and is a non-renewable resource with a single function. Contents of the invention [0003] The purpose of the present invention is to solve the foaming agent problem in the production of foam glass, and utilize the renewable resource shell as the foaming agent to produce the method of green ecological foam glass. Shell powder is activated by calcination to generate gas, and has the functions of porosity, high adsorption and sterilization. [0004] The scheme of the present invention is as follow...
