Description

A kind of halogen-free flame-retardant wood-plastic composite material and preparation method thereof
Technical field
The invention belongs to wood plastic product technical field.More particularly, to a kind of halogen-free flame-retardant wood-plastic composite material and its Preparation method.
Background technology
It by plant fiber powder (wood powder, stalk, forestry three remain thing etc.) and thermoplastic is main that wood plastic composite, which is, Raw material, a kind of novel environment-friendly composite material manufactured by physics, chemistry and biotechnology grade high technical matters.Its zero first Aldehyde, it is resistance to damage by worms, be corrosion-resistant, chemically-resistant reaction, water imbibition are small etc. at the same cause the advantages of having timber and plastics concurrently its transport service, The fields such as interior decoration, construction industry, article of furniture industry, garden landscape are widely used.But due to containing in wood plastic composite Inflammable high molecular polymer, causes the composite material highly inflammable, and molten drop is serious, and propagation of flame is very fast, in numerous applications Field (such as construction material, automobile, article of furniture etc.) is there are serious fire risk, and substantial amounts of heat, polymer in fire The toxic gas that material discharges forms huge threat to the life security and property safety of people.Thus WPC wood-plastic boards are not Fire retardant treated is the requirement for being difficult to reach code for fire prevention design of interior decoration of buildings, is essentially not allow to build as correlation Finishing material and directly use.
