Description
Technical field
The invention belongs to consumption back material prepn PC/PET technical field of alloy material in the macromolecular material, particularly a kind of transparent low temperature resistant chemical resistant properties PC/PET alloy material.
Background technology
Synthetic plastics has been made huge contribution for promoting industrial development and raising people's living standard.At the initial stage of plastics industry development, the chemicalstability of synthetic materials is that people are concerned about and one of emphasis content very much.Gone over decades, and its stability is well solved.Theatrical is that its stability has become to hinder its major reason that further develops on the contrary even to this day." agricultural film " is good illustration.Owing to be difficult to by biological degradation, can only use once, the easiest treating method is that it is committed to the flames.Doing so not only wastes resource, and causes topsoil.
The recovery of waste plastic goods and utilization have become a global problem.Traditional landfill and incineration treatment method just progressively is re-used, degraded or decomposition technique substitute.The recycling of waste plastic goods not only can be protected environment, save the energy, and had excellent economy.
Polycarbonate (PC) is a kind of engineering plastics of excellent performance, have advantages such as shock strength height, dimensional stability be good, heat-resisting, but the melt viscosity of PC is big; Mobile poor, especially be easy to stress cracking, poor solvent resistance; Under solvent and alkaline environment, be prone to stress cracking and swelling take place, limited its range of application, the solvent resistance that therefore improves PC has practical significance (Guo Weihong; Wang Xiaoguang; Xu Dongdong. low-temperature solid phase reaction is extruded the multiple net toughened structure [J] in the PET/PC alloy. SCI, 2007,28 (11): 2200-2204.).And polyethylene terephthalate (PET) is the cheaper thermoplastics of crystallinity and price; Have that crystallization velocity is fast, advantages such as chemical proofing and good fluidity; And PC is compatible with the PET part; The two blend both can keep the thermotolerance of PC, can improve its solvent resistance and stress cracking resistance again, and can improve the flowability of system.Therefore, alloy system is expected to improve preferably the solvent resistance of PC, guarantees excellent mechanical property simultaneously.
Domestic few to the research of PC/PET matrix material, especially still less, and all be the research of on the basis of PC and PET virgin material, carrying out about low temperature resistant PC/PET composite study.
The formula technique of domestic PC/PET alloy material mainly is to add the 3rd component such as solubilizing agent, elastomerics, nucleator and packing material in the PC/PET co-mixing system at present, comes further to improve the performance of blend.Guo Weihong etc. add hydrogenated styrene-butadiene-styrene block copolymers (SEBS) in the PC/PET co-mixing system, and through the twin screw extruder granulation, find in the course of processing, to produce PET and PC mutually in the network structure of IPN; Reactive chainextender PET mutually in the generation crosslinking reaction; Formed the secondary network structure, made the mechanical property of alloy material be improved significantly, particularly the notch shock performance has had the tangible (Guo Weihong that improves; Wang Xiaoguang; Xu Dongdong, etc. low-temperature solid phase reaction is extruded multiple net toughened structure [J] .2007 in the alloy, and 28 (11): 2200-2204.).Xue Jirong etc. add 3 parts ethylene-propylene acid butyl ester-glycidyl methacrylate copolymer (PTW) or 7 parts of ethylene-ethyl acrylate copolymers (EEA) in the PC/PET co-mixing system can make notched Izod impact strength by 5.5kJ/m
2Bring up to 10kJ/m
2(Xue Jirong, peaceful flat, the research [J] of PC/PET blend alloy consistency; China's plastics; 2010 01 phases).Chinese patent " a kind of low temperature resistant PC/PET matrix material and preparation method thereof "; Number of patent application: 200910192247.7; Reported the preparation method of a kind of low temperature resistant PC/PET matrix material; Chinese patent " a kind of low temperature resistant environment-friendly inflaming retarding PC/PET matrix material and preparation method thereof ", number of patent application: 200910192246.2, report the preparation method of a kind of low temperature resistant environment-friendly inflaming retarding PC/PET matrix material.More than invention all with co-mixing system in add the 3rd component solubilizing agent, come further to improve the performance of blend.
Therefore, how to prepare PC/PET matrix material, be used for the field that lower temperature resistance, oil resistant, solvent resistance and thermotolerance are had relatively high expectations with alternative PC or PC/ABS with good low-temperature performance through formulating of recipe; On the other hand, solve the problem of PC/PET improved performance aspect, drive the recovery and the utilization of PC CD waste material and PET packing waste material, for save energy, effectively utilize petroleum resources, protect environment to be of great practical significance.
