The present invention relates to the technical field of architectural ceramics, and particularly relates to an anti-
cutting and crack-resistant rock slab and a preparation method thereof, which includes a body layer, a base
glaze layer, a decorative layer, and a polished
glaze layer arranged in sequence from bottom to top; calculated by
mass fraction, the raw materials of the body layer include: 1-3 parts of
bentonite, 3-5 parts of magnesia soil, 22-28 parts of waste
brick powder, 11-15 parts of washed mud, 28-35 parts of
pyrophyllite, 12-16 parts of
albite, and 8-12 parts of mixed mud; the chemical compositions of the waste
brick powder,
pyrophyllite,
albite, and mixed mud all include SiO 2 , Al 2 O 3 , Fe 2 O 3 , TiO 2 , CaO, MgO, and K 2 O; calculated by
mass percentage, the content of SiO 2 in the waste
brick powder,
pyrophyllite,
albite, and the mixed mud is 65-75%, and the content of Al 2 O 3 is 13-20%; calculated by
mass percentage, the
mineral composition of the mixed mud includes 50-60%
kaolinite and 40-50% free
quartz. An anti-
cutting and crack-resistant rock slab proposed by the present invention is beneficial to improving the anti-
cutting and crack-resistant performance and strength on the premise of realizing low-temperature and fast firing.
