Description

A kind of Halogen-free flame-retardant anti-mildew composite and preparation method thereof
One, technical field
The present invention relates to a kind of bamboo-plastic composite material and preparation method thereof, specifically a kind of Halogen-free flame-retardant anti-mildew composite and preparation method thereof.
Two, background technology
Wood plastic composite (wood/plastic composite, be called for short " WPC ") utilizes various discarded vegetable fibre and reclaiming plastics by compound, blended, modified technique technology and a kind of emerging circumstance friendly composite material that manufactures.Current WPC is mainly used in the door and window, top board, template, floor, roof boarding, dividing plate etc. of building field.The raw material of wood-plastic products comprises: various waste or used plastics (plastic wrapping, milk bag, waste or used plastics goods, TV shell etc.) and wood powder (rice husk, stalk etc. of the scrap stock of wood working, sawdust, wood powder, crop).Not only hardness is high for wood plastic product, easy coloring, easily processing, wear-resisting, water-absorbent is little, have the plurality of advantages such as similar wood appearance, and effectively can solve " white pollution " problem that world forest resources lacks day by day and a large amount of waste or used plastics causes environment, good in mould Dai Mu, to mould for steel Novel environment-friendlymaterial material, there is good market application foreground.Research shows: wood plastic composite in the market of North America from 2003 to 2010 years with double-digit speed increment, material of construction accounts for 80% of North America wood plastic composite aggregate demand; In West Europe, vehicle material has accounted for the over half of wood plastic composite demand, separately has material of construction to account for the market of 30%; In Japan, the application of wood plastic composite in floor, wall and furniture etc. is also day by day popularized; In China, wood plastic composite has been widely used in packaging, transport, municipal administration, shipping vehicle, indoor door and window, floor, furniture, and outdoor building finishing material etc.
But meet naked light or easy firing is the critical defect of WPC when heating, this is because xylon and Plastic Resin are (in general-purpose plastics except PVC, polyethylene, polypropylene, ABS etc.) be inflammable material, direct application, particularly indoor, there is the potential safety hazard of easy initiation fire.Thus WPC is the requirement being difficult to reach code for fire prevention design of interior decoration of buildings without fire-retardant finish, does not allow as relevant constructional ornamental material in principle and directly uses.
The fire retardant mechanism of WPC relates to that xylon is fire-retardant, the problem such as plastic flame and the synergy of the two.At present, the method for respectively xylon, plastic substrate being carried out to fire-retardant finish is generally adopted for the technical study of wood plastic composite fire-retardant finish both at home and abroad.In traditional polymer flame-retarded technology, a kind of method of comparative maturity adopts halogen flame (particularly bromine system) and antimonous oxide (Sb 2o 3) compatibility, be commonly called as " halogen-antimony collaboration system ".But studies have reported that, the split product of bromo phenyl ether (PBDPO) contains dioxin violent in toxicity, and the smog that combustion processes produces is very large, and the personnel that very easily cause suffocate.Nowadays, European Union has prohibited use halogen containing flame-retardant.The fire retardant mechanism of conventional halogen-free flame-retardant system (as aluminium hydroxide, magnesium hydroxide etc.) decomposes when being heated to produce water, absorb heat and reach fire-retardant object, this based flame retardant can meet the requirement of environmental-protection flame-retardant, but amount of filler comparatively large (usually needing to reach about 40%), cause the mixing and shaping mobility of WPC to be deteriorated, affect Drawing abillity and physical and mechanical property.Adopt organo montmorillonite (OMMT) although carry out flame-retardant modifiedly also having report to wood plastic composite, but the consistency at present between polynite and resin matrix is difficult to there is substantial improvement, the fire-retardant index of OMMT modified composite material of woods and plastics is still difficult to by LOI and vertical combustion level estimate.
The flame-retardant wood-plastic composite material prepared based on the Intumescent Retardant System of ammonium polyphosphate (APP) is (as " flame-retardant wood-plastic composite material and preparation method thereof ", publication number CN1837278A), adopt APP as fire retardant main body, be charcoal source with tetramethylolmethane (PER) or starch, matrix material has possessed good flame retardant resistance, but APP add-on is comparatively large, and affects the mechanical property of flame retardant resistance wood plastic composite; Meanwhile, APP price is more expensive, also makes production cost improve.Similar also has, and publication number is the Chinese patent of CN101469082A, reports a kind of water-soluble phosphorous and nitrogenous flame ratardant, and for fire-retardant cellulose material, but fire retardant addition is large, have impact on goods physical and mechanical property, and flame retarding efficiency is more limited.Publication number is the Chinese patent of CN101812237A, adds the ammonium phosphate type fire retardant based on ammonium hydrogen phosphate, primary ammonium phosphate in recycled plastic, but also fails fundamentally to solve the problem.Chinese patent (application number: 200710173607.X) adopts ammonium polyphosphate or poly phosphate as fire retardant, first with after dissolution with solvents fire retardant, wood fibre is soaked, then halogen-free flame-retardant wood-plastic composite material is prepared, and it still uses expansion type flame retardant, and the step adding wood fibre process makes its practicality have a greatly reduced quality.Studies have reported that, Mierocrystalline cellulose contained in vegetable fibre, hemicellulose are polyol (similar with interpolation PER), thus react with APP under the high temperature conditions, serve as the effect of carbon source, thus without the need to adding " carbon forming agent " again.
Wood plastic composite, owing to being filled with a large amount of vegetable fibres, although by plastic overmold, still can providing good living environment for fungi, cause wood plastic composite to go mouldy, rot under certain wet condition, thus reduction of service life.In addition, go mouldy and surface of wood-plastic composite material can be made to produce macroscopic mould spot, affect that it is attractive in appearance, this can be very limited when WPC uses as outdoor goods.Guangdong Dimei Biological Technology Co., Ltd. Chen Juan etc. discloses " a kind of special weatherproof moldproof functional master batch for wood/plastic composite material and preparation method thereof " (publication number: CN102181090A), its composition comprises polyethylene, ZnO, N-trichloro-methylthio phthalimide, 4,5-bis-chloro-N-octyl group-3-isothiazolinone etc.Disclosed " a kind of long-acting mould-proof wood plastic composite material and preparation method thereof " (publication number: CN101767362A) of South China Normal University, its mildewproof additive is nano TiO 2, the nano-ZnO of surface modification or its composition, multilayer wood-plastic matrix material is produced by coextrusion technology, preparation technology's more complicated, makes production cost improve.Consider that the main body of wood plastic composite is vegetable fibre, the anti-mould and anti-moth characteristic of natural camphorwood powder can be utilized, not only can reduce costs, and more environmental protection.
The wood plastic composite of current report, its preparation technology is based on extrusion moulding, compression molding, and for the production of plate, sheet material based article, because WPC has added a large amount of wood powder, add a large amount of fire retardant and other processing aid again, system mobility can be caused to be deteriorated, thus to have influence on products appearance and use properties thereof.
In recent years, the flame retardant resistance modification of wood plastic composite is more and more subject to concern and the attention of people.How to use fire retardant to improve the flame retardant properties of polymer matrix composite, and suppress to produce flue gas and toxic gas when burning or the cracking of matrix material, become the key issue of new material research development and application.
