Background technology
21 century is the epoch of low-carbon economy, and Sustainable development becomes to be the theme, and environmental protection concept is rooted in the hearts of the people, and the national policy guiding also begins to focus on the environmental protection aspect.Automobile and plastic industry become peak point wave, beginning in 2009, and China becomes the production and consumption first big country of automobile and plastics.Under international environmental protection situation pressure, China is to begin to greatly develop easy degradative plastics-biological plastics, and the POLYACTIC ACID industry has obtained significant progress.No matter in the POLYACTIC ACID compound probability, still processing modified industry, POLYACTIC ACID (PLA) technology reaches its maturity.Yet; POLYACTIC ACID is because its result's singularity; Exist not enough at aspects such as toughness, resistance to deteriorations; And traditional method of modifying is that nano-particles filled or the elastomer-filled guaranteed performance that all is difficult to are stable, has reduced the original thermotolerance of PLA material, high transparent, high rigidity and readily degradable simultaneously significantly.The introducing of nucleocapsid technology becomes the way that solves an above difficult problem.With a kind of and the higher shell monomers of POLYACTIC ACID avidity, coated elastomer or inorganic nano-particle, filling components is guaranteed dispersed the time, improved itself and the avidity of POLYACTIC ACID system greatly, finally make the material monolithic performance reach optimum.
Summary of the invention:
Method involved in the present invention is through in the POLYACTIC ACID system, introducing Core-Shell Polymer Particles, and then when reaching the original mechanical property of maintenance system, thermal property, fluid property and the transparency, increases substantially POLYACTIC ACID system toughness; Simultaneously, in system, add auxiliary agents such as inhibitor, improve the poly-lactic acid material resistance to deterioration.Finally prepare easy degraded, shock resistance and aging-resistant fascia POLYACTIC ACID PP Pipe Compound.The Core-Shell Polymer Particles that present method is introduced, its shell monomers are a kind of in basic methyl acrylate, Jia Jibingxisuanyizhi, the NSC 20956, and this shell monomers and POLYACTIC ACID have good avidity; Nuclear layer monomer is a kind of in Bing Xisuandingzhi, ethyl propenoate, vinylbenzene, the ethene, and its shock resistance and elongation at break aspect have excellent performance.
At the core-shell polymer preparatory phase; Through the control to the temperature in the process, system tension force, reaction times (comprising that nucleation time and shell coat the time), shell and these several kinds of conditions of nuclear layer monomer addition, evenly (size distribution is interval: 80～130nm), dispersed height, shell coat nano level Core-Shell Polymer Particles completely finally to prepare size distribution.
In core-shell polymer preparing carriers process; With the Core-Shell Polymer Particles and the polylactic acid raw material of certain proportion (30～70 parts), add tensio-active agent (0.5～3 part), coupling agent (0.5～5 part), fully mix; Dry 12h; Extrude pelletizing through twin screw extruder then, after water-cooled, air-cooled, pelletizing, drying, obtain the core-shell polymer carrier.
At last, with the polylactic resin more than the prior dry 12h, with the core-shell polymer carrier with certain adding proportion (5～30%), through the high mixer blend, dual-screw-stem machine is extruded, pelletizing, air-dry, finally obtains fascia POLYACTIC ACID PP Pipe Compound.Through the fascia inside gadget that this PP Pipe Compound processes, intensity and toughness are balanced, are prone to degraded, can be applicable to the new-energy automobile field.
