Preparation method for light porous domestic ceramic

The invention discloses a preparation method for a light porous domestic ceramic. The preparation method comprises the steps that (1) slurry is prepared, specifically, feldspar, quartz, clay and waterare mixed, a water reducing agent is added, the pH value is adjusted, and uniform stirring and mixing are carried out; (2) foaming is carried out, specifically, a foaming agent and a foam stabilizerare taken and added into the slurry, and stirring is carried out so as to obtain slurry with foam uniformly distributed; (3) forming is carried out, specifically, the slurry obtained in the step (2) is injected into a plaster mold, standing is carried out for 15min-2h, residual slurry is poured out, then the mold is kept standing for 0.5-1h, and then a blank is taken out and obtained; (4) drying is carried out, specifically, the blank is placed in drying equipment to be dried, and the drying temperature is 60-100 DEG C; and (5) sintering is carried out, specifically, the dried blank is placedat a high temperature to be
