Description
Technical field
The present invention relates to a kind of graftomer and contain the Wood-plastic material and the preparation method of this graftomer, be meant especially and will add the vegetable fibre powder after the thermoplastic resin graft modification, through proportioning, mixing, extrusion plasticizing moulding, a kind of dual nature matrix material that has timber and plastics concurrently that obtains.
Background technology
Wood-plastic material is the novel environment friendly material that just rose in recent years in the world, this material with thermoplastics or thermosetting resin with after wood fibre mixes with certain proportion, add corresponding adjuvants through the structural section bar that High Temperature High Pressure makes, be assembled into products such as packaging pallet, tr and building slab again.Product has that raw material sources are wide, cost is low, good mechanical property, scantlings of the structure good stability, can reuse, do not absorb water, not be afraid of and damage by worms and antiacid characteristics such as alkaline-resisting, and the ultimate compression strength and the hardwood of product are suitable, and repeat usage is than timber-work height.
In the various wood plastic products that appear on the market at present, its preparation technology generally can be divided into two kinds: the first is passed through tackiness agent, adopt die press technology for forming to make product, the various food and drink tools and the pallet of Xiao Shouing mostly adopts this technology in the market, as CN1066382C, US4883719, FR2355627A relates among the JP62152802A; Its two employing and the filling-modified identical manufacture craft of common plastics are about to the vegetable fibre powder as filler, mix mutually with polyolefin resin such as polypropylene, polyethylene etc. under the effect of expanding material and other processing aids, obtain product by extrusion moulding again.Wherein, a kind of technology in back is because wood meal absorbs water easily, and the characteristic that polarity is also very strong makes that the consistency of itself and plastics is very poor, and processing technology is had relatively high expectations, machine-shaping device to Wood-plastic material has certain particular requirement, is a difficult point of present Wood-plastic material preparation.Now, generally set about improving from processing units and prescription two aspects.
Improvement to processing units: on the one hand, its water content of the wood meal of seasoning is higher, directly use often causes that goods bubble, burn even in the machine barrel implode, on the other hand, even if wood meal through the thorough drying processing, because its thermal degradation temperature and forming process temperature are extremely approaching, work in-process also can decompose generation gas because of part.Therefore, the gas barrier that the drying temperature of wood powder, time and production efficiency and processing units are good all is main moulding process difficult point, the special-purpose forcing machine that present used solution is to use special drying plant or specific production wood to mould.As US6, the method for two kinds of charging opening equipment of usefulness of being mentioned in 280,667, first charging opening is as adding wood meal usefulness, and its effect is to remove moisture content in the wood powder, and second charging opening adds thermoplastic resin.Disclose a kind of heating under vacuum formula measurement charging device among the CN1296881A, also be in Production Flow Chart, to finish the operation that removes moisture, and carried out the secondary drying processing again.The core of these devices all is to remove moisture content in the wood meal, but because to there being the uncertain of the not general and improvement effect of equipment after the equipment improvement, so be difficult to carry out in the production.
Improvement to prescription: the one, the coupling agent method, utilize lipid acid, silane coupling agent and titanate coupling agent are handled wood powder to improve the consistency of wood meal and plastics, its principle is the polar group and the wood powder reaction of coupling agent, and the good affinity that utilizes its non-polar group and plastics improves the consistency of this powder and plastics, as US5,981,631 and US5,866, the usefulness that relates in 641 contain be no less than 16 carbon atoms lipid acid wood meal is carried out pre-treatment, and then and thermoplastic resin, mention among the US4820749 silane coupling agent is grafted to earlier on the molecular chain of wood powder fiber, to improve the linkage force with resin material.Though these methods have obtained certain effect, owing to can only link so material property is relatively poor with weak bond between coupling agent and plastics, and this method needs many one production processes, spends also bigger; Another kind is the expanding material method, utilize the polyolefin resin of maleic anhydride graft to make expanding material improving consistency owing to contain carboxyl in the expanding material, can with the hydroxyl generation esterification in the wood powder, thereby reduce the moisture absorption and the polarity of wood powder, with the consistency of raising with plastics.But the expanding material of this way need be selected the expanding material base-material according to the base-material of the finished product, makes the versatility of product limited, and prepares expanding material in advance and also make Production Flow Chart elongated.In addition, to the especially requirement very strict (usually less than 5%) of water content of requirement of wood powder, the additionally a large amount of drying plant of interpolation, and production process also can only be an intermittent type, can't form continuous production behind the compositional refinements.
JP57192466 discloses a kind of technology of preparing, be that unsaturated silane is grafted on the polyolefin resin under the effect of peroxide initiator, and then with the wood meal blend, since the silane coupling agent on this modified resins can not with wood powder fiber bonding effectively, can influence the material property of gained.
