The invention provides a preparation method of a light thermal insulation wall material. The preparation method comprises blending 50-90 parts by weight of silicon-calcium slag, 10-50 parts by weight of active calcium silicate, 10-25 parts by weight of portland cement, 2-5 parts by weight of desulfurized gypsum and 50-100 parts by weight of water, carrying out molding and carrying out stream curing under normal pressure at a temperature of 80-100 DEG C. The preparation method can be carried out under normal pressure at a lower temperature and greatly reduces a calcium silicate thermal insulation material production cost. The light thermal insulation wall material obtained through the preparation method has good comprehensive properties and well satisfies building material practical application requirements. 本发明提供种轻质保温墙体材料的制备方法，该制备方法将50～90重量份的硅钙渣、10～50重量份的活性硅酸钙、10～25重量份的硅酸盐水泥、2～5重量份的脱硫石膏和50～100重量份的水混合、成型，随后在常压和80～100℃的蒸汽条件下进行蒸养养护。本发明的制备方法能够在常压和较低温度下进行，从而大大降低了硅酸钙保温材料的生产成本；此外，利用该方法制得的轻质保温墙体材料综合性能良好，能够较好地满足建筑材料的实
