Abstract

The invention provides a manufacturing technique for a sound-insulating foam glass and relates to the technical field of glass production. The manufacturing technique comprises the following steps: (1) mixing and crushing the following raw materials in parts by weight: 100-125 parts of waste bottle glass, 4-8 parts of quartz, 1-3 parts of titanium carbide, 0.5-1.5 parts of antimonous oxide, 0.5-1.6 parts of adhesives, 1-4 parts of acetate, 0.5-1.5 parts of surface active agent and 0.5-2.5 parts of release agent, thereby acquiring mixture powder; (2) melting the mixture powder in a tunnel kiln under the melting temperature at 720-760 DEG C, thereby acquiring a liquid mixture; (3) uniformly foaming the liquid mixture for 30-40min under the foaming temperature of 660-670 DEG C; (4) while reducing the temperature to 500-520 DEG C, feeding into an annealing furnace, reducing to 100 DEG C in the annealing furnace at the rate of 5-8 DEG C / min, exiting from the annealing furnace, placing into an air-tight room, cooling to 30 DEG C and forming; (5) coating a layer of transparent organic protecting film on the surface of the annealed foam glass. The manufacturing technique has the advantages of low heat conductivity coefficient, excellent sound insulation, high strength, completeness and high heat stability.

Description

Technical field [0001] The invention belongs to the technical field of glass production, and specifically relates to a production process of sound insulation foam glass. Background technique [0002] Foam glass is a light and high-strength building material and decoration material with excellent heat insulation (cold insulation), sound absorption, moisture resistance, and fire resistance. The service temperature range is minus 196℃ to minus 450℃. Class A is non-flammable and has the same life span as buildings. , The moisture permeability coefficient is almost 0. Although other new thermal insulation materials are emerging in endlessly, foam glass is playing an increasingly important role in low thermal insulation, moisture-proof engineering, sound absorption and other fields due to its permanence, safety, and high reliability. Its production is the reuse of waste solid materials, which is an example of protecting the environment and obtaining substantial economic benefits. [00...
