Integrated boards are being used more and more widely in decoration due to their unique material properties such as environmental protection, moisture-proof, mildew-proof, sound insulation, heat preservation, fire prevention, and convenient installation. In some areas, integrated boards have even become the first choice material for decoration. The main reason for this phenomenon is its environmental protection and convenient installation advantages.

Integrated boards are divided according to materials and can usually be divided into: bamboo and wood fiber integrated walls, aluminum integrated walls, and stone-plastic integrated walls. Since bamboo and wood fiber has a relatively wider market acceptance, this article uses bamboo and wood fiber integrated walls as the example. It is made of a base material produced by high-temperature composite production of bamboo powder, wood powder, polymer aldehyde-free polymeric components and other environmentally friendly materials, and is then coated with environmentally friendly decorative materials. Because the base material is made of environmentally friendly materials and compounded at high temperatures. The various raw materials that make up the base material have changed their material properties during the high temperature process. Almost all the volatile chemicals contained in the base material have been released after high temperatures, so choose qualified ones. The integrated board base material itself produced from raw materials rather than recycled materials can be very environmentally friendly. In the end, the key link in determining the environmental protection of integrated walls is surface coating.

PUR hot melt adhesive is much more environmentally friendly than cold glue. It is widely used in auto parts, textile industry, shoemaking industry, book binding, food packaging industry, household appliances, and electronic products. PUR hot melt adhesive is used in the building materials and home furnishing industries. Glue and PUR hot melt adhesive machines are already the first choice.

Compared with cold glue, PUR (polyurethane hot melt glue) is a reactive adhesive.

It has the following significant advantages:

A. It has the remarkable characteristic of irreversible moisture reaction - it does not rebound when encountering hot or cold environments;

B. 100% solid, no solvent - no harmful substances such as VOC, benzene, formaldehyde, etc. are emitted;

C. High initial bonding strength - short reaction time;

D. UV resistance - convert harmful UV light into harmless heat energy to protect materials;

E. High production efficiency - equivalent to 5 times the efficiency of cold glue equipment production;

F. High environmental performance - E0 level environmental protection.
