詳細(xì)內(nèi)容:PA11 HB006∴PA11 HB006 PA11 HB006∴PA11 HB006 PC/PBT alloy PC/PBT alloy, PBT has excellent mechanical properties, chemical corrosion resistance and easy molding. The blending of PBT and PC can improve PC fluidity, improve processability and chemical resistance. Because PBT is a crystalline polymer, it is easy to phase separation when mixed with PC, and its interfacial adhesion is not good, so its impact toughness is not ideal. A certain amount of elastomers is usually added to improve the impact strength of the blends. The zinc salts of thermoplastic elastomer ethylene / methacrylate copolymers play a role in Compatibilization and toughening of PC/PBT blends. The addition of some nucleating agent can improve the crystallinity of the blends; adding a small amount of low pressure polyethylene in PC/PBT blend system, can improve the flowability of the blend, play a toughening effect on blends, and can improve the appearance of alloy; added in PC/PBT ethylene / vinyl acetate copolymer can further enhance the compatibility and improve impact resistance strength; esterification reaction between PC and PBT, can improve the compatibility, Japanese researchers using PC and PBT in the presence of a transesterification catalyst, prepared PC/PBT blends, good comprehensive performance, but also has better transparency; and PC with similar refractive index of glass fiber reinforced PC/PBT, not only the excellent comprehensive performance system. And good transparency, can do instead of glass materials. Foreign PC/PBT alloy products are mainly used for automobile bumpers, packaging film materials, car base and seat, etc. PET PET has good mechanical properties and chemical resistance. PC/PET has both the rigidity and heat resistance of PC, and the solvent resistance of PET. Moreover, the addition of PET can improve the processing fluidity of PC. Domestic researchers found that when the PC/PET ratio is 1/3, the interface layer forms between the two phases, and the PC/PET compatibility is best at this time. In addition PC and PET ester exchange reaction is one of the best ways in which the catalyst compatibility, selection of a very large impact on the reaction, the catalyst of lanthanide catalyst and the traditional study found (such as titanium) have higher catalytic activity, and there is no side effects, also found that the ester exchange reaction occurs mainly in the interface. In PC/PET blends, the toughness and impact strength of the alloy can be improved by adding elastomer, such as butyl acrylate. The research and development of PC alloy change rapidly, there are a variety of PC alloy has been developed and marketed, especially PC modified polyester blends, such as PET/PCL (multiblock copolyesters by ethylene glycol, a low molecular weight polycaprolactone and terephthalic acid copolymer made) blended with PC modification; by 1, modified polyester PC blended with 4 - cyclohexane two methanol, ethylene glycol and terephthalic acid, can significantly improve the PC flexural modulus and tensile strength; polycaprolactone with glass fiber as reinforcing material, promote the PCL and PC were mixed with modified transesterification catalyst, transparent material can get good processing performance, high rigidity; poly (1, 4 - two - 1 4 cyclohexane carboxylic acid, cyclohexane two methanol) ester modified PC, PC can significantly improve the transparency and yellowing resistance, can be used as optical materials; liquid crystal polyester modified PC It can be used to improve the melting and mechanical properties of PC.
