Abstract

The invention discloses a refractory sintered clay hollow brick, and belongs to the technical field of hollow bricks. The refractory sintered clay hollow brick comprises the following raw materials in parts by weight: 55 to 60 parts of clay, 12 to 16 parts of attapulgite, 10 to 14 parts of silica fume, 8 to 12 parts of glass fibers, 18 to 20 parts of ceramic microbeads, 5 to 9 parts of cement, 3 to 5 parts of corundum powder, 3 to 5 parts of quartz powder, 4 to 6 parts of aluminum oxide, 7 to 9 parts of yttrium oxide, 6 to 8 parts of brominated epoxy resin, 2 to 4 parts of organic bentonite, 1 to 3 parts of starch, 2 to 4 parts of chlorinated paraffin, 4 to 5 parts of melamine cyanurate, 5 to 6 parts of tricresyl phosphate, 1 to 3 parts of antioxidants, 1 to 2 parts of water reducers, 1 to 3 parts of preservatives and an appropriate amount of water. The invention further discloses a preparation method of the refractory sintered clay hollow brick. The refractory sintered clay hollow brick disclosed by the invention is simple to prepare, corrosion resistant and heat-insulated, relatively high in strength and fire resistance, and long in service life.

Description

technical field [0001] The invention relates to the technical field of hollow bricks, in particular to a refractory sintered clay hollow brick and a preparation method thereof. Background technique [0002] Clay hollow bricks are made of clay and shale as the main raw materials, which are processed, shaped and sintered. The percentage of the total area of ​​holes in the hollow brick to the area of ​​the brick where it is located is called the porosity of the hollow brick, which should generally be above 15%. Compared with solid bricks, hollow bricks can save a lot of land, soil and fuel for burning bricks, reduce transportation weight; reduce labor intensity during brick making and masonry, speed up construction progress; reduce building weight, increase building layers, and reduce construction costs . [0003] Clay hollow brick is the main wall material commonly used in the construction industry. Due to its advantages of light weight and less consumption of raw materials,...
