A preparation method for outer wall body lagging material, comprises the following steps:

(1) by 600-800 DEG C of calcining 2-3h after the mixing of activity charcoal powder, calcium hydroxide and float stone, mix with Ethylhexyl stearate after cooling, 60-80 DEG C, 400-500r/min stirs 1-2h, grind rear 50-100 mesh sieve;

(2) add white cement, hydrogen peroxide, tartarus and phthalate, cellulose, 200-300 DEG C, 150-250r/min process 30-60min, add all the other raw materials, stir after cooling, after packing and get final product.

Advantage of the present invention is:

1. thermal conductivity is little, and caking ability is high, water resistant, Wind-Pressure Resistance, shock resistance, and weathering resistance is strong;

2. there is stronger fire retardant performance, during high temperature, do not produce obnoxious flavour, safety non-pollution;

3. cost performance is high, constructs convenient, has higher economic benefit.
