Abstract

The invention discloses an anti-mildew halogen-free flame-retardant smoke-suppression wood-plastic composite material, which comprises the following components in parts by mass: 25-70 parts of plastic resin, 10-50 parts of plant fiber powder, 5-10 parts of camphor wood powder, 0.5-20 parts of a compatibilizer, 0-15 parts of a toughening agent, 10-35 parts of a flame retardant and a synergist, 2-5 parts of a thermal stabilizer, 0-1 part of an antioxidant and 1-4 parts of a lubricating agent. According to a method for preparing the wood-plastic composite material with a two-step fusion method disclosed by the invention, the interfacial compatibility can be improved effectively, and the flame retardance of the wood-plastic composite material is enhanced on the premise of keeping high mechanical property; and moreover, the using amount of ammonium polyphosphate serving as a major flame retardant is reduced. Compared with the conventional wood-plastic composite material, the wood-plastic composite material disclosed by the invention has a simple production flow, has the technical effects of flame retardance, smoke suppression and mildew resistance, and is widely applied to occasions such as indoor and outdoor architectural decoration, and the like.

Description

1. Technical field [0001] The invention relates to a wood-plastic composite material and a preparation method thereof, in particular to a mildew-proof, halogen-free, flame-retardant, smoke-suppressing wood-plastic composite material and a preparation method thereof. 2. Background technology [0002] Wood / plastic composite (WPC for short) is an emerging environment-friendly composite material manufactured by using various waste plant fibers and recycled plastics through compounding, blending and modification technology. At present, WPC is mainly used in doors and windows, roof panels, formwork, floors, roof panels, partitions, etc. in the construction field. The raw materials of wood-plastic products include: various waste plastics (plastic packaging, milk bags, waste plastic products, TV shells, etc.) Wood-plastic products not only have many advantages such as high hardness, easy coloring, easy processing, wear resistance, low water absorption, and wood-like appearance, but...
