Description
The present invention relates to toughened plastics and preparation method thereof, say further, the present invention relates to utilize rubber and plastic blend and the high toughness plastic that makes and the preparation method of this kind plastics.
Plastics more and more are subject to people's attention as a kind of widely used material.Souheng Wu according to du pont company is published in POLYMER INTERNATIONAL VOL.29, NO.3, and the article on (1992) 229-247 is described: plastics are because macromolecular chain characteristic attribute difference can be divided into toughened plastic and brittle plastic.Chain entanglement density Ve≤0.15mmol/ml, characteristic ratio C when plastics
∞〉=7.5 o'clock, can mainly form crazing for external shock and dissipate with matrix, belong to brittle plastic; Chain entanglement density Ve 〉=0.15mmol/ml, characteristic ratio C when plastics
∞≤ 7.5 o'clock, can mainly produce shear yielding for external shock and come dissipation energy with matrix, belong to toughened plastic.No matter toughened plastic still be brittle plastic all can be by further improving toughness with blend rubber.
Many scientists have carried out extensive studies to plastic toughening theory and method for toughening.The eighties Souheng Wu has proposed exceeding of plastic toughening and has oozed theory, point out in rubber toughened plastics, the condition of plastics generation brittle-ductile transition is: rubber is as during less than a specific critical range τ c, brittle-ductile transition taking place promptly apart from τ between its particle of disperse phase.Owing to have relational expression between the particle diameter d apart from τ and rubber phase between the particle of rubber phase: d=τ [k (π/φ r)
1/3-1]
-1, so when rubber particles diameter d during less than critical diameter dc, brittle-ductile transition promptly takes place.That is to say that its particle diameter of dispersive rubber phase is more little, the easy more generation brittle-ductile transition of toughened plastics.In the technology of existing rubber toughened plastics, with rubber as toughner and plastic blend and obtain toughened plastics.4517319 described U.S. Dupont companies select isocyanic acid polyurethanes copolymer elastomer reinforced polyformaldehyde for use as U.S. Pat, the German Hoechst company that European patent EP 120711 and EP121407 are put down in writing selects diolefine graftomer elastic body toughening polyoxymethylene for use, European patent EP 117664 companies of described Japanese Asahi Chemical Industry select the patent FR8519421 of styrene block copolymer elastomer reinforced polyformaldehyde and French Atochem (FR) Cedex 22, 94091 Paris La Defense, France for use, FR8803877, FR9512701, FR9609148, the patent JP127503/97 of Mitsui KCC, the patent JP190634/97 of Japan Kishimoto Sangyo Co., Ltd, the technology with rubber toughened plastics such as the maleic anhydride graft second third glue toughened polyamides of JP190635/97 record.There is following weak point in it: (1) is difficult to be controlled at small range as the rubber size of disperse phase under the blending condition of present rubber and plastic processing, average rubber phase particle dia is greater than 200nm.If will realize brittle-ductile transition, then need the rubber of big umber, thereby cause the toughened plastics inflexible to reduce; (2) rubber phase particle diameter instability, along with the variation of factors such as course of processing middle shear rate, the rubber phase particle diameter in the toughened plastics is always in variation; (3) the rubber phase particle diameter is very inhomogeneous; (4) rubber content can not surpass 40%, otherwise is prone to " Hai-Hai " phase structure, even phase reversion occurs, makes the degradation of toughened plastics.
Therefore, it is little to the purpose of this invention is to provide a kind of contained rubber phase median size, and even, the stable high toughness plastic of rubber size.Phase reversion also do not occur even its rubber content reaches 70%, rubber remains disperse phase.These high-ductility plastics also have rigidity preferably when having higher toughness.
