Abstract

The invention provides a refractory hollow brick containing fluorite slag and a preparation method of the refractory hollow brick. The refractory hollow brick comprises the following raw materials inparts by weight: 20-30 parts of fluorite slag, 10-15 parts of lime, 6-8 parts of volcanic rock powder, 5-8 parts of modified nano-attapulgite, 36-50 parts of waste calcium silicate plate, 3-6 parts oftitanium dioxide powder, 1-4 parts of ferrochrome slag powder, 0.5-1 part of calcium bicarbonate, 5-9 parts of silicon carbide powder, 24-34 parts of aluminum oxide, 9-13 parts of corundum, 11-15 parts of muscovite powder, 2-5 parts of glass beads, 1.6-1.9 parts of sodium carboxymethyl cellulose, 1-3 parts of water glass, 5-7 parts of octyl epoxy stearate, 20-22 parts of modified ceramsite and 4-7 parts of aluminum phosphate. The refractory hollow brick containing fluorite slag prepared in the invention has good fire resistance and is suitable for large-scale production and application.

Description

Technical field [0001] The invention relates to the technical field of refractory bricks, in particular to a refractory hollow brick containing fluorite slag and a preparation method thereof. Background technique [0002] The development of industry and economy in human society and the improvement of human living standards have formed a social system of large-scale production, high consumption and multi-abandonment. In the context of the increasing importance of energy and natural resource protection in the world, with the adjustment of industrial policies and the improvement of environmental protection awareness, the use of other industrial wastes has also shown an upward trend. Most countries have a problem with industrial waste during construction. The economic, environmental and technical advantages of the company have shown positive interest. Many industrial wastes have been proven to be recycled. Various industrial wastes or urban construction wastes are added as raw materi...
