Background technology
Polycarbonate, English name Polycarbonate is called for short PC.PC is colourless or little yellow thermoplastic engineering plastic of a kind of unformed, odorless, nontoxic, highly transparent, has excellent physical and mechanical properties, shock-resistance excellence especially, tensile strength, flexural strength, compressive strength height; Creep properties is little, dimensional stabilizing.PC also has good thermotolerance and lower temperature resistance, has stable mechanical property in wide temperature range, dimensional stability, and electrical property and flame retardant resistance can be at-60~120 ℃ of following life-time service; No sharp melting point is molten state at 220~230 ℃; Because the molecular chain rigidity is big, resin melt viscosity is big; Water-intake rate is little, and shrinking percentage is little, the dimensional precision height, and dimensional stability is good, and the film ventilation property is little; Belong to self-extinguishing; Stable to light, but ultraviolet resistance not, good weatherability; Oil resistant, acidproof, not anti-highly basic, oxidizing acid and amine, ketone are dissolved in chlorinated hydrocarbons and aromatic solvent, easily cause hydrolysis and cracking for a long time in water, and shortcoming is poor because of fatigue resistance, is easy to generate stress cracking, and good solubility-resistence is poor, and wear resistance is not good enough.
With PC and PBT blend, both can overcome deficiencies such as the PC chemical proofing is poor, forming process is not good, remedy the not high shortcoming of PBT shock strength again simultaneously, can obtain good comprehensive performances.PC/PBT alloy ubiquity in the market rigidity and the not good problem of thermotolerance, though can reach result of use by the content that improves PC, cost increases.
Polybutylene terephthalate (PBT) has high heat resistance, toughness, resistance to fatigue, self-lubricating, low-friction coefficient, and weathering resistance, water-intake rate are low, only be 0.1%, in wet environment, still keep various rerum naturas (comprising electrical property), electrical insulating property, but volume resistance, dielectric loss are big.Heat-resisting water, bases, acids, oils but hydrolytic resistance is poor, crystallization rapidly under the low temperature, good forming ability.Shortcoming is that notched Izod impact strength is low, and molding shrinkage is big.Polyethylene terephthalate (PET) has similar structure with PBT, except that chemical resistance that possesses PBT and favorable mechanical performance, its rigidity and life-time service temperature will be higher than PBT, but the second-order transition temperature height of PET, crystallization velocity is slow, molding cycle is long, shaping cycle is long, and molding shrinkage is big, poor dimensional stability, the moulding of crystallization is fragility, and thermotolerance is low etc.
PC and PBT, PET blend both can be overcome deficiencies such as the PC chemical proofing is poor, forming process is not good, remedied simultaneously PBT, shortcoming that the PET shock strength is not high again, can obtain good comprehensive performances.PC/PBT/PET is typically unformed/crystallization/semi-crystalline polymer system, though be all polyester certain consistency is arranged, and directly there is crystallinity difference in the blend meeting, and consistency is suppressed; Need to add the consistency that suitable toughness reinforcing compatibility performance improves ternary system greatly, to improve shock strength; In addition PC belongs to self-extinguishing, though so alloy also has certain flame retardant resistance, flame retardant rating is difficult to reach service requirements, therefore be necessary ternary alloy is carried out flame-retardant modified, with satisfied result of use under given conditions.
