Abstract

The invention discloses a low cost antibending ceramic roller rod, comprising aggregate, a matrix material and resin, wherein the aggregate has a main raw material formula of 30-60 parts of ceramic roller rod waste material in parts by weight, the matrix material has a main raw material formula of 15-40 parts of cordierite, 2-15 pars of aluminium oxide, 0.1-8 parts of yttrium oxide and 15-35 parts of clay in parts by weight; the resin selects water soluble resin in 0.1-2 parts by weight. Correspondingly, the invention further discloses a preparing method of the low cost antibending ceramic roller rod. By adopting the low cost antibending ceramic roller rod and the preparing method thereof, the ceramic roller rod waste material is reused, the problem that a corundum-mullite ceramic roller rod easily generates bending and deforming in a quenching belt or a large temperature difference region, and the condition of sliding of a tile in a roller kiln is improved.

Description

Technical field [0001] The invention relates to the technical field of processing and manufacturing ceramic rollers, in particular to a low-cost anti-bending ceramic roller and a preparation method thereof. Background technique [0002] Roller kilns are widely used in the production of construction, daily-use and sanitary ceramics. Ceramic rollers, as a key component of roller kilns and rolling kilns, play the role of carrying ceramic products and completing the sintering process, directly affecting The development of the ceramic industry. [0003] At present, corundum-mullite ceramic rollers are the most widely used, but in the actual production process, a large amount of corundum-mullite roller waste is often produced. The domestic secondary utilization rate of waste is very low, so the roller waste is generally It is regarded as a non-degradable industrial solid waste pollutant, but also a waste of mineral resources. The widely used corundum-mullite ceramic rollers are mainly ...
