Description
Technical field
The present invention relates to wood plastic composite field, specifically a kind of flame-retardant wood-plastic composite material.
Background technology
Wood plastic composite is composited by string and plastics, has the feature performance benefit of timber and plastics concurrently, is one
New environment-friendly materials are planted, its product is mainly used as the substitute of timber, but due to the primary raw material wood in wood plastic composite
Fiber and plastics belong to combustible material, using there is certain potential safety hazard, it is necessary to carry out flame retardant treatment.Polyolefin and timber
It is fire-retardant frequently with inorganic combustion inhibitor, halogen containing flame-retardant and phosphonium flame retardant etc..Due to unfavorable shadow of the halogen containing flame-retardant to environment
Ring, the halogen-free flameproof of material is paid much attention to by people, and inorganic combustion inhibitor flame retarding efficiency is low, Flame Retardancy is reached
Certain requirement, filling quality fraction need to be up to 40-60%, so can be very big on the mechanical mechanics property influence of material, it is difficult to
Reach use requirement.
The content of the invention
The invention provides a kind of flame-retardant wood-plastic composite material, to solve above-mentioned technical problem.
A kind of flame-retardant wood-plastic composite material, by weight, includes the raw material components of following parts by weight：Polypropylene 20-40
Part, 40-55 parts of wood fibre, 20-30 parts of maleic anhydride grafted polyethylene, 10-15 parts of fire retardant, 3-5 parts of plasticizer, light are stable
4-6 parts of agent, 2-5 parts of antioxidant, 1-3 parts of lubricant.
It is preferred that, the fire retardant is in ammonium phosphate, sulfamic acid, sulfamic acid ammonia, phosphoguanidine or Guanidine Sulfamate 99
One or more.
It is preferred that, the lubricant is microcrystalline wax.
It is preferred that, a kind of flame-retardant wood-plastic composite material by weight, includes the raw material components of following parts by weight：Poly- third
30 parts of alkene, 48 parts of wood fibre, 25 parts of maleic anhydride grafted polyethylene, 13 parts of fire retardant, 4 parts of plasticizer, 5 parts of light stabilizer,
3.5 parts of antioxidant, 2 parts of lubricant.
Beneficial effects of the present invention：
This flame-retardant wood-plastic composite material excellent in mechanical performance of the present invention, with fabulous rigidity, impact property
With good dimensional stability；Fire retardant is added in the present invention, the thermal degradation speed of wood plastic composite is reduced, improves material
800 DEG C of carbon yields of material, flame retardant effect is notable.The addition of other fire retardant influences not on the tensile strength of wood plastic composite
Greatly, the bending strength to wood plastic composite is significantly improved.It is fire-retardant in the case where the mechanical mechanics property of material is basically unchanged
Effect significantly, is worthy to be popularized.
