Background technology
Wood plastic composite (WPC), is a kind of main by answering that material and plastics based on timber or cellulose are made
Condensation material, it is simply that by a certain proportion of wood fiber (such as wood powder, powder of straw, cotton stalk powder, bamboo powder, shell powder etc.) through pre-place
Reason is allowed to a kind of new material being combined into thermoplastic polymer resin or other materials；The both environmental protections of this new material
There is again good mechanical stability, but the two big raw material wood fiber of composition wood plastic composite and polyolefin are all inflammabilities
Material, is also combustible material for this this composite, and the fire resistance giving wood plastic composite good is that this materials application is sent out
The needs of exhibition；Individually the fire-retardant research to timber and the wood fiber has a lot, typically has phosphorus-nitrogenated flame retardant；Boron flame retardant；Contain
Halogen fire retardant；Other inorganic salts etc.；But main based on phosphorus-nitrogenated flame retardant it is considered to be optimum wood fire retardant,
Phosphorus, two kinds of elements of nitrogen play synergism in wood fire retardant and improve flame retardant effect；But these fire retardants almost have one
Common feature, it is simply that reduce the thermal degradation temperature of the wood fiber significantly, this may result in and cannot be carried out adding of composite
Work；Research for polyolefin flame-retardant is also a lot, and its flame resistant method is frequently with halogen containing flame-retardant and antimony oxide (Sb2O3) join
Close and use；Metal hydroxides (Al (OH)3、Mg(OH)2) fire retardant；Expansibility flame-proof agent；Ammonium polyphosphate flame retardant etc.；Halogen
Fire-retardant is the focus of polyolefin flame-retardant research, expanding fire retardant polyolefin/Wood Fiber Composites is carried out dual fire-retardant be this
The focus of the fire-retardant research of composite；But the interpolation of fire retardant often deteriorates the mechanical property of composite, therefore to resistance
The research of the research flame-proof composite material of retardant composite material to study interface compatibility, heat stability and anti-flammability, to obtain simultaneously
Obtain preferable flame-proof composite material.
Wood plastic composite has preferable machinability, the most anticorrosive, beautiful, generous, but, being in of its defect
Not good enough in its mechanical property, to this end, people seek solution route, once there is people to be re-introduced into stone powder in wood plastic composite, used
