The invention discloses a phosphate-based composite material and a preparation method thereof. The preparation method of the composite material comprises the following steps: mixing a phosphate adhesive with kaolin, and mechanically stirring to obtain a slurry; preparing a curing agent; adding the curing agent to the obtained slurry; adding a high temperature resistant filler; adding a wear resistant filler; adding short quartz fibers to the obtained slurry, and stirring until uniform mixing; pre-curing the obtained slurry at 100-120DEG C for 0.5-4h; cooling, stirring the pre-cured and cooled slurry to obtain a pasty dough-shaped material with good flexibility and strong plasticity; and carrying out hot pressing at 110-250DEG C under 60-120MPa for 4-8h to obtain the phosphate-based composite material. The method has the advantages of short flow and low cost, and the composite material prepared in the invention has the advantages of high strength, good toughness, high temperature resistance, chemical corrosion resistance and wear resistance.
