At present, indoor partitions are generally installed with paper-faced gypsum boards on both sides of the keel, and the walls are hollow, with low heat insulation and sound insulation performance. Commonly used lightweight partition walls and partition wall materials mainly include GRC boards (glass fiber reinforced cement boards), gypsum boards, etc.; GRC boards use glass fibers, and the product cost is high; Difference. And the use of light steel keel will make the construction more difficult. The biggest disadvantage of existing partition walls and partition products is that recycling is particularly difficult, which is not conducive to recycling and environmental friendliness.

In order to overcome the above shortcomings, a new type of composite board that can be used as a partition wall and partition is needed. It is low in cost and has the functions of partition, heat insulation, sound insulation, waterproof and fire prevention, etc. It is quick to install and can be recycled.

The composite board of the utility model is superimposed with a light non-combustible foamed cement board for heat insulation in the middle of the frame. Compared with the existing partition wall/partition, the sound insulation value is high and the thermal conductivity is low. It has both sound insulation and quick installation, recyclability, and excellent appearance quality, which meets the strategic requirements of the country's advocacy of building "ecological civilization and beautiful China";

Flame-retardant medium-density fiberboard or cement fiberboard layer can effectively use fast-growing low-quality wood, processing residues and crop straw, and improve resource utilization;

The combination of fiberboard layer and cement board makes it obtain excellent non-combustibility and flame retardancy, which fundamentally enhances the fire protection of partition walls/partitions, and obtains the performance of not being afraid of insects and rotting fungi;

The composite board integrates the advantages of foamed cement and wood, with low cost, simple operation process, and small space occupation. Flat, without plastering;

Since the composite panel belongs to the type of factory prefabrication and on-site assembly, it is the first choice for the partition wall material of the second decoration of the building.
