The invention relates to the technical field of building materials, in particular to a heat preservation permeation plate. A method comprises the steps of raw material drying, wherein EPS raw materialpermeation plate antiflaming minimum particles are dried; foaming, wherein the raw material is poured into a hopper and is fed into a foaming machine through an elevator, and a foaming pressure meteris set to be 0.45 MPa, steam is led in, and when the temperature of the foaming machine is 80 to 90 DEG C, the foamed foam raw material is taken out of the foaming machine; thirdly, curing, wherein the foamed raw material is put into a normal-temperature stock bin to be cured, the foam particles are expanded again, and the curing time is commonly 20 to 30 hours; fourthly, plate making, wherein the cured foam particles in the third step enter a plate making machine through a sucking fan, it is required that pressure of steam led into the plate making machine is 0.7 to 0.8 MPa, a pressure reducing valve is arranged on t
