In recent years, driven by the policy, the prefabricated construction industry has developed rapidly, and the prefabricated integrated board has become the preferred material for ultra-low energy consumption buildings。thermal conductivity（W/m.k）≤0.045.Prefabricated integration board is used in large industrial plants, warehouses, gymnasiums, supermarkets, hospitals, cold storage, mobile rooms, building layers, clean workshops and places requiring heat insulation and fire prevention. Sandwich plate appearance is beautiful, beautiful color, the overall effect is good, it sets load-bearing, heat preservation, fire prevention, waterproof in one, and without two decoration, is a kind of widely used especially in the construction site of temporary facilities such as offices, warehouses, walls and other applications, more reflects the modern construction site civilization construction, Especially in terms of rapid installation and putting into use, and in terms of turnover and reuse index of assembled and detachable materials, it has obvious advantages in significantly reducing the cost of temporary facilities at construction sites. It will be an indispensable new lightweight building material. When used in combination with photovoltaic products, it can achieve energy self-sufficiency and reduce environmental pollution. And can be applied to high altitude environment and do not have energy supporting places.
