Description

A kind of flame-retardant wood-plastic phase change composite material
Technical field
The present invention relates to a kind of flame-retardant wood-plastic phase-change energy-storage composite material and its powder, particle and plate product, belong to Building material field.
Technical background
Continuous improvement with people to environmental resource attention degree, wood plastic composite has drawn in the application of building field Play government and the attention of the public.Wood plastic composite is to use wood-fibred or string filling, enhanced modified thermoplastic material, Have the performance of timber and plastics concurrently, be section bar, material or other products through hot pressing, extrusion or injection molding, instead of timber and modeling Material, have the advantages that plasticity is strong, be not cracked, waterproof, protection against the tide, anti-corrosion, anti-mildew and good processability.And phase-change material can be with By changing the change of physical state within the scope of certain temperature, store and discharge substantial amounts of heat energy, with energy storage density it is big, The features such as inhaling (putting) hot temperature approximately constant.Wood-plastic material is combined with each other with phase-change material, you can obtain having two kinds of materials concurrently The wood moulding phase-change material of advantage.
Plastics are main in Wood-plastic material to be play a part of to cohere filler and transmission stress.For preparing wood plastic composite Thermoplastic mainly has polyethylene, polypropylene, polyvinyl chloride, polystyrene, acrylonitrile/butadiene/styrene copolymer, poly- Formaldehyde etc..
Wood material for wood plastic composite is not the narrow sense concept of wood powder, is being commonly called as string.Plant Fibres typically have three kinds of woody fiber, Herbaceous Fiber and rattan standing grain fiber.Therefore, " wood " in this concept of wood material is Refer to the lignin in string；" powder " refers to the geometry state of string.Intensity, the rigidity of wood plastic composite mainly take It is certainly species, form, chemical constituent and the content of wood material in reinforcing material.Result of study shows, the increasing of fibrous wood shavings Pretend with best, the humidification of lumber fibre is taken second place, and is finally wood material.Wood material/wood shavings/lumber fibre it is conventional Particle diameter is 20~400 mesh.Shape, size, seeds of wood material etc. have an impact to composite material strength.
Organic phase change material, various polymer, natural fiber belong to inflammable or combustible, therefore composite is easy Burning fire, belongs to inflammable class material, it is restricted in application process.Therefore, research flame-retardant wood-plastic phase transformation is answered The burning of condensation material, pyrolysis characteristicses and to carry out flame retardant treatment to it be very important.Halogen in traditional polymer flame-retarded technology Fire retardant (particularly bromine system) is so that addition is low, flame retardant effect substantially, it is moderate and be taken seriously, cooperateed with antimony oxide Act on (being commonly called as " halogen-antimony collaboration system "), flame retardant effect is more notable.The cooperative effect sought between different flame retardant, improves resistance Fuel efficiency rate, the mechanical property for improving flame-retardant wood-plastic phase-change energy-storage composite material, reduction production cost, are flame-retardant wood-plastic phase transformations One of main contents of composite research and development.Publication number CN104262753A patent discloses a kind of wood moulding phase-changing energy storage material Preparation method, but its content of the invention is not directed to fire resistance, can be restricted in market process.
Research currently for wood moulding phase change composite material is also seldom.And prepare has good moldability, fire resistance simultaneously Excellent wood moulding phase change composite material, be not yet seen has of this sort technology to be disclosed in the prior art.By wood moulding material Material is combined with phase change composite material, you can obtain wood moulding phase change composite material.Wood moulding phase change composite material is a kind of feature Composite, not only the characteristic with timber floor, the high heat storage performance also with phase-change material, can be combined with floor heating, utilize peak Paddy electricity valency, reduces energy resource consumption, further improves residence comfort.
