The present invention carries out modification by rubber to aglite, and by scientific and reasonable grating, effect of heat insulation is better outstanding, the thermal conductivity of the plastering mortar that the use embodiment of the present invention 1 dry-mix obtains is 0.15W/(mK), than traditional mortar heat conductivity coefficient 0.93W/(mK) reduce by 6 times; Accumulation of heat value is down to 3.6W/ (mk) by 11.37W/ (mk), has reduced by 3 times; Due to the raising of thermal resistance, radiant heat is down to 2-8 degree to the temperature head of substrate insulated material production, and thermal stress reduces 2.36*10
-2, the stress cracking causing because of thermal stress is effectively controlled; The present invention can external wall thermal insulation system provide thermal technology reinforcement, more effectively plays heat-blocking action, reduces energy consumption.
