Abstract

The invention provides a low-cost foam glass heat insulating material. The low-cost foam glass heat insulating material comprises the following raw materials: industrial waste glass, porcelainized powder, a foaming agent, a cosolvent, graphene oxide, borax, antimonous oxide and a foaming accelerator, wherein the porcelainized powder comprises low-temperature porcelainized powder, medium-temperature porcelainized powder and high-temperature porcelainized powder; the foaming agent is selected from one in carbon black, silicon carbide, calcium carbonate, dolomite dust, flogopite, graphite, manganese dioxide, sodium silicate, trichlorofluoromethane and dichlorodifluoromethane; the cosolvent is selected from one or more in sodium carbonate, sodium silicofluoride, sodium benzoate, sodium salicylate, para aminobenzoic acid and Tween; the foaming agent is selected from one in lithium stearate and zinc stearate. The low-cost foam glass heat insulating material greatly improves the performance of foam glass, reduces the foaming temperature, increases the foaming range, reduces communicating holes, and improves the yield.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to a low-cost foam glass thermal insulation material. Background technique [0002] Foam glass is an inorganic non-metallic glass material made of cullet, foaming agent, modifying additive and foaming accelerator after finely pulverizing and uniformly mixing, then melting, foaming and annealing at high temperature. It is known as " Permanent thermal insulation that never needs to be replaced". This kind of insulation material has a low bulk density, high mechanical strength, and a thermal conductivity of about 0.058W / (m·K), which inherently has a good insulation effect. In addition, foam glass is easy to process, has a long service life (same life as the building), and has a fire-resistant rating of Class A. It is a fire-proof, heat-preserving, corrosion-resistant, and sound-absorbing material with superior performance. However, the reason why this ma...
