Description
[technical field]
The invention belongs to Wood-plastic material technology of preparing and field of Environment Protection, be specifically related to a kind of novel stone wood plastic composite.
[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 a certain proportion of wood fiber (such as wood powder, powder of straw, cotton stalk powder, bamboo powder, shell powder etc.) is made through pretreatment
A kind of new material being combined into thermoplastic polymer resin or other materials；This new material not only environmental protection but also have
There is good mechanical stability, but the two big raw material wood fiber of composition wood plastic composite and polyolefin are all inflammability materials
Material, is also combustible material for this this composite, and giving the good fire resistance of wood plastic composite is the development of this materials application
Needs；Individually the fire-retardant research to timber and the wood fiber has a lot, typically has phosphorus-nitrogenated flame retardant；Boron flame retardant；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 jointly
Feature, it is simply that reducing the thermal degradation temperature of the wood fiber significantly, this may result in the processing that cannot be carried out composite；Right
Also a lot of in the research of polyolefin flame-retardant, its flame resistant method is frequently with halogen containing flame-retardant and antimony oxide (Sb2O3) coordinate make
With；Metal hydroxides (Al (OH)3、Mg(OH)2) fire retardant；Expansibility flame-proof agent；Ammonium polyphosphate flame retardant etc.；Halogen-free flameproof
The focus of polyolefin flame-retardant research, expanding fire retardant polyolefin/Wood Fiber Composites is carried out dual fire-retardant be this be combined
The focus of the fire-retardant research of material；But the interpolation of fire retardant often deteriorates the mechanical property of composite, therefore to fire-retardant multiple
The research of the research flame-proof composite material of condensation material to study interface compatibility, heat stability and anti-flammability, to obtain reason simultaneously
The flame-proof composite material thought.
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
In molding novel stone wood plastic composite, but, due to the problems such as interface compatibility, the mechanicalness of the composite finally given
Can be poor.
[summary of the invention]
The technical problem to be solved in the present invention is to provide a kind of novel stone wood plastic composite, to solve to hinder in prior art
The interpolation of combustion agent can deteriorate the mechanical property of wood plastic composite, and introducing stone powder is used for molding stone wood plastic composite, due to
The problems such as interface compatibility, the problem such as the mechanical performance of the composite finally given is poor.The novel stone wood of the present invention is moulded multiple
Condensation material good flame retardation effect, strong shock resistance, toughness is strong, and water absorption rate is little, not only obtains excellent fire resistance but also maintain
The novel preferable mechanical property of stone wood plastic composite, is the excellent novel stone wood plastic composite of a kind of performance, can extensively apply
