The invention discloses a thermal-shock resistant refractory brick and relates to the technical field of manufacturing of refractory materials. The thermal-shock resistant refractory brick comprises, by weight, 30-40 parts of mullite powder, 10-20 parts of fine andalusite powder, 5-15 parts of fine sillimanite powder, 5-8 parts of Guangxi clay and 3-5 parts of silica powder and is obtained by mixing the ingredients, making blank, drying and baking. Compared with the prior art, the thermal-shock resistant refractory brick is resistant to high temperature and corrosion and good in thermal-shock resistant performance, and refractoriness under load is increased. In addition, the thermal-shock resistant refractory brick is not easy to crack and damage when used for an industrial rotary kiln, and service life is prolonged.
