Abstract

The invention discloses a high-strength light-weight thermal-insulation refractory brick. The brick is characterized by being prepared from, by weight, 60-80 parts of high alumina, 30-40 parts of fly ash, 20-30 parts of chamotte clay, 10-30 parts of diatomite, 10-20 parts of corundum-mullite powder, 5-15 parts of floating beads, 3-8 parts of silica powder, 5-10 parts of ceramsite, 2-8 parts of andalusite powder, 5-10 parts of nano inorganic oxide, 8-15 parts of vitrified microspheres, 3-8 parts of a binding agent, 2-6 parts of a foaming agent, 1-5 parts of a water reducing agent and 100-120 parts of water. The high-strength light-weight thermal-insulation refractory brick has the advantages of being lightweight, high in compressive strength, low in heat conductivity coefficient, low in linear change rate, good in fire resistance, low in production cost and the like, the requirement of the industry can be met, and a good application prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-strength lightweight heat-insulating refractory brick and a preparation method thereof. Background technique [0002] Energy is scarce in the world, and various thermal equipment are important facilities in industrial production, and they are also large energy consumers. Therefore, the refractory layer and heat insulation layer of various thermal equipment require heat preservation, fire resistance, and heat insulation. Long-term safe use, energy saving and consumption reduction guarantee greater economic benefits. [0003] At present, lightweight heat-insulating refractory brick is a kind of heat-insulating refractory material with high porosity, low bulk density, low thermal conductivity and heat capacity, and certain compressive strength. The heat storage loss of industrial kiln masonry and heat loss on the surface of the furnace body generally account for a...
