Abstract

The invention relates to a plastic-wood composite material, especially a high efficiency flame retardant plastic-wood composite sheet and its preparation method. In the invention, tris(dibromopropyl) phosphate is employed to improve the flame retardance of wood powder, and decabromodiphenyl oxide and antimonony oxide are adopted for their synergism to improve the flame retardance of plastic particles. Additionally with other auxiliary agents and an extrusion technology, the high efficiency flame retardant plastic-wood composite sheet can be formed. The high efficiency flame retardant plastic-wood composite sheet provided in the invention has the advantages of convenient production and manufacturing, low production cost, environmental friendliness, excellent mechanical property and flame retardance, and can be widely used in many fields needing flame retardance.

Description

technical field [0001] The invention relates to a wood-plastic composite material, in particular to a high-efficiency flame-retardant wood-plastic composite board and a preparation method thereof. Background technique [0002] Wood-plastic composite material is a new type of composite material that has been booming at home and abroad in recent years. Compared with pure wood, it does not require anti-corrosion treatment, is environmentally friendly, does not require daily maintenance, has a longer service life than wood, does not absorb moisture, and does not rot. Insect-proof, insensitive to cold and hot environments. It has good strength performance, excellent adjustable performance, UV light stability, good colorability, wide source of raw materials, can be made into any shape and size according to needs; easy to process, can be sawed, planed and bonded , or fixed with nails and bolts, it can be completed with woodworking tools, and the nail holding power is significantly...
