In the past few decades, China's construction industry has been booming, which has greatly promoted the growth of the national economy. In the face of the increase in the cost of land transfer, the rise in labor prices and the gradual improvement of people's awareness of energy conservation and environmental protection, the construction industry is facing increasing competitive pressure. In order to improve the core competitiveness-assembly partition new industrial model came into being.

Prefabricated partition building is a new type of building production mode. It is characterized by component factory prefabrication production and on-site assembly and installation, standardized design, factory production, assembly construction, integrated decoration and information management. It integrates R & D, production, sales and service, R & D, design, manufacturing, on-site assembly, etc., to realize the sustainable development of energy saving, environmental protection and full cycle value of building products.

The state has long encouraged the development of prefabricated partition buildings. Since 2015, the planning of prefabricated buildings has been intensively introduced. At the end of 2015, the evaluation standards for industrialized buildings were released, and it was decided to promote prefabricated buildings nationwide in 2016 and make breakthrough progress. On November 14, 2015, the relevant departments issued the outline for the modernization of the construction industry. By 2020, prefabricated buildings will account for more than 20% of new buildings, and by 2025, prefabricated buildings will account for more than 50% of new buildings. In 2016, the state issued guidance on vigorously developing prefabricated buildings, reiterating the significance of the development of prefabricated buildings. According to the "13th Five-Year Plan", the proportion of the total area of new green buildings in the total area of new buildings will increase from 20% in 2015 to 30% in 2020. Relevant agencies predict that the incremental scale of the new green building market will reach 210 billion billion yuan. However, China's annual external wall area is about 1 billion square meters, of which the thermal insulation and decoration integrated board accounts for about 10-15% of the area. Therefore, the prospect of thermal insulation and decoration integrated board is unlimited, and the market capacity will reach more than 50 billion yuan.

Construction industrialization, residential industrialization and urbanization require the active promotion of prefabricated buildings. The key index to evaluate the level of industrialization of buildings is the degree of assembly of external walls. The promotion and application of prefabricated lightweight concrete exterior wall panels is in line with the national industrial policy of green building and building energy conservation, and is an important part of the sustainable development strategy of the construction industry. Integrated thermal insulation board is a good product for energy-saving and thermal insulation of building exterior walls. How to combine with prefabricated partition building is an important topic of prefabricated building.

On the premise of maintaining the excellent thermal insulation performance and decorative effect of the thermal insulation and decoration integrated board, how to achieve the basic mechanical performance index required by the system itself, how to better combine the thermal insulation and decoration integrated board with the prefabricated wall joint, and how to improve the installation accuracy, a series of problems have plagued most manufacturers of thermal insulation and decoration integrated board. Huarui honeycomb has made a breakthrough in the good combination of thermal insulation and decoration integrated board, steel pipe bundle and sand aerated wall board, creating a number of precedents for the application of thermal insulation and decoration integrated board in prefabricated partition buildings.
