A kind of halogen-free flame-retardant polyethylene wood-plastic composite board

technical field

The utility model belongs to the field of materials, in particular to a halogen-free flame-retardant polyethylene plastic-wood-steel composite board.

Background technique

With the continuous development of the social economy "replacing wood with plastic and steel with plastic", the demand for decorative panels in many industries has also increased rapidly. For example, the interior decoration design of buildings requires a large number of fireproof decorations with various colors. sheet. At present, most of the common decorative panels on the market are ordinary aluminum-plastic panels or steel-plastic composite panels. These panels have the disadvantages of poor fire resistance, toxic smoke when burned, and poor heat insulation, heat preservation, and sound insulation. In recent years, with the further improvement of environmental protection, safety, recyclability, and meeting the requirements of green ecological development and market demand, higher requirements have been put forward for decorative building materials. The development of halogen-free flame-retardant polyethylene-wood-plastic composite panels has caused received extensive attention from the industry. The application of halogen-free flame-retardant polyethylene wood-plastic composite technology products in the application of metal composite board core materials is currently blank in the market.
