Abstract
The invention discloses a flame-retardant wood-plastic composite. The composite is prepared from the following components by mixing: wood flour, high-density polyethylene, maleic anhydride grafted polyethylene and a flame retardant. According to the wood-plastic composite, various composites such as mehtyl phenyl polyborosiloxane, nano silica and ammonium polyphosphate are added to the components; by means of the flame retardant, the thermal degradation rate of the wood-plastic composite is reduced, the carbon residue rate of the composite at 800 DEG C is increased, and the flame-retardant effect is remarkable; besides, through the addition of the flame retardant, little influence is produced on the tensile strength of the wood-plastic composite, but the bending strength of the wood-plastic composite is obviously improved; under the condition that the mechanical performance of the composite is basically not changed, the composite has remarkable flame-retardant effect and is worth popularizing.
Description
Technical field
The present invention relates to wood plastic composite field, be specifically related to a kind of flame-retardant wood-plastic composite material.
Background technology
Wood plastic composite is to be composited by Plant fiber and plastics, have the feature performance benefit of timber and plastics concurrently, it is a kind of novel environment-friendly materials, its product is mainly used as the succedaneum of timber, but owing to the primary raw material wood fiber in wood plastic composite and plastics broadly fall into combustible material, there is certain potential safety hazard in application, it is necessary to carries out flame treatment.Polyolefin and timber fire-retardant frequently with inorganic combustion inhibitor, halogen containing flame-retardant and phosphonium flame retardant etc..Due to the halogen containing flame-retardant adverse effect to environment, the halogen-free flameproof of material is subject to the great attention of people, inorganic combustion inhibitor flame retarding efficiency is low, make Flame Retardancy can reach certain requirement, filling quality mark need to up to 40-60%, so can the mechanical mechanics property of material be affected very big, it is difficult to reach instructions for use.
Summary of the invention
Present invention aim at, it is provided that a kind of mechanical mechanics property is good, the wood plastic composite that flame retardant effect is high, the technical solution adopted in the present invention is:
A kind of flame-retardant wood-plastic composite material, is mixed by weight percentage by following components:
Wood powder 40-55 part
High density polyethylene (HDPE) 5-10 part
Maleic anhydride grafted polyethylene 25-40 part
Fire retardant 10-15 part.
One of preferably, described fire retardant includes aminomethyl phenyl polyborosiloxane, nano silicon, one or more in APP.
One of preferably, described fire retardant is by aminomethyl phenyl polyborosiloxane, nano silicon, and APP is 1:0.2:0.8 mixing composition according to weight ratio.
The present invention provides the benefit that relative to prior art: the wood plastic composite of the present invention, employ aminomethyl phenyl polyborosiloxane, nano silicon, the multiple composite of APP adds in component, fire retardant reduces the thermal degradation speed of wood plastic composite, improve 800 DEG C of carbon yields of material, flame retardant effect is notable.Additionally the hot strength on wood plastic composite of adding of fire retardant affects little, and the bending strength of wood plastic composite is significantly improved.When the mechanical mechanics property of material is basically unchanged, flame retardant effect is notable, is worthy to be popularized.
Detailed description of the invention
Below with reference to embodiment, the design of the present invention and the technique effect of generation are clearly and completely described, to be completely understood by the purpose of the present invention, feature and effect.Obviously; described embodiment is a part of embodiment of the present invention, rather than whole embodiment, based on embodiments of the invention; other embodiments that those skilled in the art obtains under the premise not paying creative work, belong to the scope of protection of the invention.
Embodiment 1: a kind of flame-retardant wood-plastic composite material, is mixed by weight percentage by following components:
Wood powder 50 parts
High density polyethylene (HDPE) 8 parts
Maleic anhydride grafted polyethylene 30 parts
Fire retardant 12 parts.
Embodiment 2: a kind of flame-retardant wood-plastic composite material, is mixed by weight percentage by following components:
Wood powder 53 parts
High density polyethylene (HDPE) 7 parts
Maleic anhydride grafted polyethylene 26 parts
Aminomethyl phenyl polyborosiloxane 7 parts
Nano silicon 1.4 parts
APP 5.6 parts.
Above the better embodiment of the present invention is illustrated, but described in the invention is not limited to
Embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the premise without prejudice to spirit of the present invention, and these equivalent modification or replacement are all contained in the application claim limited range.
