Background technology
Traditional structural product is to use steel as seat stool, door and window, division board, fence etc., and wood materials or conventional plastic are like Vilaterm, Vestolen PP 7052, other various polyolefine and blend polyolefine etc.As a rule steel and wood material structural strength high, be widely used, can use and make a lot of family products.But shortcoming is steel to get rusty easily and is easy to the burn into poor plasticity; Plastics are then easy ageing of product, and cost is bigger than higher, resource consumption, environmental facies are bigger to DR.
The present invention is a kind of thermoplastic composite polyolefine material of having of plant cellulose filler that contains.Can be used for compressed moulding, rotation molding, extrusion moulding and injection moulding.This composite products can be widely used in and substitute traditional structural product, such as the tables, chairs and benches of office appliance etc., daily necessities (basin, tank, door and window, fence), electronic product casing, automobile and aircraft industry inside fitting component etc.These structural component require its mechanical property, must meet certain standard like bending property, tensile property, shock strength etc.Therefore, to constantly improve these mechanical propertys of material on the one hand, also will consider some other important factor on the other hand: like working temperature, fire resistance, economic benefit, environmental protection factor etc.
In the past decade, use the technology of lignocellulose filled plastics to obtain significant progress at home and abroad.And cellulose wadding be because its fiber properties can better improve mechanical property, particularly snappiness and the impact resistance of plastic polymer, and therefore this filling technique just progressively is caused concern.Invented the polyolefin plastics that a kind of 5-25% of containing Mierocrystalline cellulose is filled like U.S. Pat 7041716 B2.But because Mierocrystalline cellulose has and the visibly different physicochemical property of xylogen, adding Mierocrystalline cellulose in a large number can increase plastics substrate and cellulosic heterozygosis performance, and following process is as extruding the difficulty of processing with the injection moulding aspect in addition.Thereby big limitations a large amount of uses of Mierocrystalline cellulose in polyolefin matrix.
In sum, how better cellulose-binding and polyolefin plastics have become a problem that is worth discussion.To improve plastics substrate and cellulosic cement properties on the one hand, make it have better mechanical property; The workability of not obvious again reduction plastics on the other hand improves the ratio of Mierocrystalline cellulose packing material as much as possible, and the protection environment that economizes on resources reduces cost.
The present invention studies innovation on this basis, has filled up domestic blank, also than the like product performance of present commercialization the leading greatly and similar products at home and abroad of great lifting, particularly impact resistance has been arranged in the world.
Summary of the invention
This patent has been invented a kind of polymer composite, comprises olefin plastics matrix, cellulose wadding, one or more above grafting coupling agents with high reactivity group, possibly comprise one or more above internal lubricant or external lubricants, possibly comprise one or more impact modifier, also possibly comprise a kind of and more than one dispersion agent etc.Raw material is through the super-dry pre-treatment, and Hybrid Heating is extruded, and is processed into the product that shape is fit to commercial prodn.Can be used for follow-up various compressed mouldings, rotation molding, extrusion moulding and injection moulding.

The Mierocrystalline cellulose wide material sources, it can be various waste and old paper, the press reclaimed waste paper that paper-making industry is recycled; Also can be various natural Mierocrystalline celluloses: like straw, flax, jute etc.Mierocrystalline cellulose must be handled through bake drying through the mechanical workout moulding again.What pay particular attention to is: the thermal destruction that drying temperature and time of drying can not make Mierocrystalline cellulose when drying treatment, take place.Cellulosic usage ratio is 10%-70% in this patent, increases significantly than the highest about 30% filling ratio in the present known patent of invention.
The grafting coupling agent is the high polarity lower melting point additive that contains the overactivity group, is used for the Mierocrystalline cellulose and the hydrophobic polymkeric substance of grafting possess hydrophilic property.It can also improve the adding proportion of Mierocrystalline cellulose in polyolefin matrix when improving mechanical property.In the course of processing, the common usage ratio of coupling agent is 1%-10%.
Lubricant has two kinds of different types usually, i.e. internal lubrication type lubricant and external lubrication type lubricant.Internal lubricant is the fluidizer of half lysotype, significantly reduces the plastics viscosity that macro manifestations is come out in the course of processing through the consistency of improving between the inner different micelles of material, to reduce the difficulty of the course of processing., polymer esterification thing saponified, amides, lipid acid etc. like polyethylene wax, OPE, paraffin, metal.And exterior lubricant is to reduce the plastic processing difficulty through lubricious polymeric thing and processor metallic surface, like Fatty Alcohol(C12-C14 and C12-C18), low ester class, ethyl vinyl acetic monomer etc.The main internal lubricant that uses among the present invention, massfraction is 0.5%-10%, also can contain a certain proportion of exterior lubricant.
Impact resistance is a very important mechanical property of matrix material.Some material such as rubber have very high impact strength, but many high performance materials often show very low shock-resistance when low temperature or envrionment temperature.Generally speaking, can improve the impact resistance of plastics through adding some properties-correcting agent.
In addition, this patent also possibly contain some other different types of additive, like dispersion agent, fireproofing agent, stablizer, inhibitor, pigment etc.Also maybe be because the impure a certain proportion of inorganics etc. that contains of raw material.
What this patent was invented is a kind of matrix material that contains the organic cellulose weighting material of external phase thermoplastic polyolefin hydrocarbon substrate and discontinuous phase.The disperse phase that comprises in the matrix material is dispersed in the polyolefin matrix with ultra-fine fibre or particle more uniformly, and its dispersive state with the naked eye is difficult to observation.The disperse phase Mierocrystalline cellulose also possibly comprise particulate state, sheet, plate dress, thread ribbon, cotton-shaped or other shape composition forms.
The polyolefin matrix of external phase can be Vilaterm, Vestolen PP 7052, other polyolefine or the olefin copolymer etc. of any kind.C711-RNA propylene copolymer, the LDPE 1965T of Sabic company and Lupolen 1800U new LDPE (film grade), FPC 100 Vestolen PP 7052 that Lyondellbasel company provides that Flexirene MT 40A linear low density polyethylene, Eraclene MS 80 high density polyethylene(HDPE)s, the Dow company that provides like Eni company produces.Also can be through the impure Vilaterm that contains pigment and other impurity recycling,, other Vestolen PP 7052, other polyolefine or olefin copolymer.Produce the PPC Renenerat olefin copolymer of recycling like Rotho company oneself, Regranulat PP random reclaims Vestolen PP 7052.Polyolefin matrix mass ratio in matrix material is 30%-90%.
The cellulosic filler of discontinuous phase possibly contain various coarse relatively shapes, like sheet, wire, thread, and cotton-shaped, bulk, ribbon shape, bigger particulate state and various non-homogeneous shape.Mierocrystalline cellulose as packing material may reside in much natural or the non-natural raw material.Contain cellulosic natural fiber, like Caulis Sacchari sinensis fiber, flax, jute, hemp, sisal hemp, cotton, ramie, coir, straw, bamboo etc.The Mierocrystalline cellulose source also can be the sub product in the various industrial production lives, like a large amount of paper rubbish etc. of discarding of paper-making industry, old and useless newspaper, books, printing industry generation.Mierocrystalline cellulose shape through processing is having aspect size, long-width ratio, the form etc. various appearances to show, such as bulk, pie, powdery, sheet, cotton-shaped, particulate state etc.Mierocrystalline cellulose and polyolefin matrix can bind in very wide scope.According to the difference of end-use, the ratio of Mierocrystalline cellulose and polyolefin matrix may be different.Mass ratio can change arbitrarily between from 10% to 70%.Because Mierocrystalline cellulose has very strong hydrophilicity, can absorb the central moisture of air, have suitable moisture content.Compound extruding adds man-hour these moisture and can bring difficulty very big in the processing, must carry out dry pre-treatment; But, therefore must take all factors into consideration the temperature and time of drying treatment owing to the at high temperature long-time degraded easily of Mierocrystalline cellulose sex change.In circulation dryer, cellulosic drying temperature needs between 40 ℃-120 ℃, the time between 30 minutes to 12 hours for well.Between 60 ℃-100 ℃ and 1 hour to 6 hours is good.
Coupling agent has played crucial effects, can improve the mechanical property of composite plastic greatly.Effective coupling agent that the present invention uses comprises a kind of polyolefin-wax of maleic anhydride modified modification at least, and concrete to select according to the polyolefin matrix of finally selecting for use be foundation.For example: the metallocene polyethylene wax Licocene PE MA4351 of maleic anhydride modified contains the high grafting property group up to 6%; Maleic anhydride modified Vestolen PP 7052 metallocenes wax Licocene PP MA6452 TP; Maleic anhydride modified Poly Propylene Wax Licocene PP MA 7452; The linear low density polyethylene wax of maleic anhydride modified; The high density polyethylene waxes Bondyram4108 of maleic anhydride modified and Bondyram 5101; Styrene-ethylene/the butylene of maleic anhydride modified-benzene butylene copolymerization wax (SEBS) Kraton FG 1901X; The Poly Propylene Wax Orevac CA100 of maleic anhydride modified etc.Polyolefin-wax through the senior property maleic anhydride of modification contains the high reactivity anhydride group, it its can be fully with the chemical bond of hydrophilic cellulose and hydrophobic polyolefine graft reaction Cheng Xin.
