Description
Technical field
The present invention relates to a kind of plastic-metal and preparation method thereof, relate in particular to a kind of high-performance bio-degradable plastics metal and preparation method thereof.
Background technology
Plastic-metal is a kind of advanced composite material, take plastics as matrix, by special design and formula, make its finished product not only keep the intrinsiccharacteristic of polymer itself, as: low-cost, be easy to machine-shaping, environmental protection, high performance, multifunction etc., and outward appearance has typical metal texture and gloss, this kind of type material will be widely used in the fields such as mobile terminal, automobile, household electrical appliances.
Poly(lactic acid) is a kind of wide concerned complete Biodegradable polymer material, and it has the general feature of general plastic, and as higher rigidity and intensity, easily machine-shaping, is applicable to multiple fabrication process condition.Widespread use in medical equipment, daily living article at present.But poly(lactic acid) is a kind of hard brittle material at normal temperatures, its notched Izod impact strength is only about about 30J/m, far below conventional general plastic as PP, ABS, PC etc.Poly(lactic acid) toughness reinforcing, the one, by copolymerization, on polylactic acid molecule chain, introduce another kind of flexible molecule chain, the regularity of polylactic acid molecule chain is declined, thereby reduce the crystal property of poly(lactic acid), make molecular chain kindliness better, tough property improvement, but the method cost is higher; The 2nd, by contour machining procedures such as stretch orientation, anneal, improve the mechanical properties such as shock strength, but this method improvement amplitude is limited, be difficult to fundamentally solve the problem of toughness deficiency; The 3rd, by blending method, add the better polymkeric substance of elastomerics, softening agent or toughness, this method cost is lower, and material choice scope is wide, practical, is specially adapted to the modified plastic industry that cost control is had relatively high expectations.
Conventional metalluster effect adopts the mode of spraying to reach conventionally, such as silver color, pearly-lustre or various colour flicker effect, but in spraying process, volatilize a large amount of solvents, make direct labor face serious potential safety hazard, the method for spraying causes fraction defective high simultaneously, and operation is numerous and diverse, goods are recycled difficulty etc., make production cost higher.Aluminium powder and pearly pigment are directly added in resin binder, can realize metalluster effect.Under regular situation, in resin, add after aluminium powder and pearly pigment, because of the consistency of aluminium powder and pearly-lustre and resin matrix poor, very easily produce current mark, the main avidity with matrix resin and aluminium powder is relevant, inorganic aluminium powder or pearly pigment particle surface only have hydroxyl or carboxyl seldom, and common resin material does not generally have the group that can react with it, both consistencies are poor, under the strong shearing condition of injection moulding, it is consistent that aluminium powder pigment and matrix resin material are difficult to reach mobility, easily forms current mark.
Summary of the invention
The object of the invention is to provide a kind of high-performance bio-degradable plastics metal, has the biodegradable while of high tenacity, makes its surface have excellent metal appearance gloss.
Another object of the present invention is to provide a kind of manufacture method of biodegradable polylactic acid plastic-metal.
