The invention relates to a manufacturing method of diatomite porous brick. The weight percentages of raw materials of the brick are as follows: diatomite 55-75 percent, fly ash 20-30 percent and wood dust 5-15 percent. The manufacturing method comprises the steps of compounding, melting, extrusion molding, brick blank drying, brick blank calcination, and final production inspection and preservation. The inventive brick utilizes diatomite as main ingredient and fly ash and wood dust as adjuvant, has a plurality of uniformly-distributed round or square hole on the front surface, and has hollow structure instead of solid structure of the prior wall brick. Therefore, the inventive brick has the advantages of higher strength, good fire-proof and heat-insulating effects, less waste of diatomite resource and low cost. The diatomite porous heat-insulating brick is, so far, the better light-weight wall material with effects of both heat insulation and heat preservation.
