The invention belongs to the technical field of a construction material, in particular to a desert sand sintered decorative brick and a manufacture method thereof. The desert sand sintering decorative brick is prepared from the following ingredients in mass percent: 10 percent to 90 percent of desert sand, 0 percent to 50 percent of shale, 0 percent to 50 percent of coal gangue, 0 percent to 50 percent of clay and 5 percent to 15 percent of bentonite. The manufacture method comprises the technical steps of ingredient pulverizing and screening, material proportioning, stirring, ageing, forming, cutting, drying, surface glazing and roasting for manufacturing the desert sand sintered decorative brick. On one hand, the invention uses a large amount of desert sand, and can clear the sand for desert regions, and on the other hand, waste slag of the shale and the coal gangue is used as ingredients, so the invention has the characteristics of energy saving, waste utilization and reasonable resource configuration. At the same time, the invention improves the heat preservation and thermal insulation performance of buildings through glazing the surface of a brick body and changing the external appearance attribute of the traditional sintered brick.
