Description
Technical field
The invention relates to a kind of ceramic fiber and strengthens flame-retardant PBT/PET alloy and preparation method thereof, belongs to macromolecular material and forming process field thereof.
Background technology
Ceramic fiber is a kind of fibrous light refractory materials integrating conventional insulation material, refractory materials premium properties, and its diameter is generally 2 μm ~ 5 μm, and length mostly is 30mm ~ 250mm, and fiber surface is smooth cylindrical, and cross section is normally circular.Its constructional feature is void content high (being generally greater than 90%), and air vent aperture and specific surface area large.
Because the air in the pore of ceramic fiber has good heat-blocking action, thus in fiber, the size of air vent aperture and the character (ventilate or hole of holding one's breath) of pore have conclusive impact to its heat conductivility.In fact, the internal organizational structure of ceramic fiber is a kind of mixed structure be made up of solid fabric and air, its microstructure feature is all exist with the form of external phase in solid phase and gas phase, therefore, in such an embodiment, solid matter exists with filamentous form, and forms external phase skeleton, gas phase then continued presence among the skeleton gap of filamentary material.Just because of ceramic fiber, there is this structure, make that its void content is higher, air vent aperture and specific surface area comparatively large, thus make ceramic fiber have excellent heat-proof quality and less volume density.Be used for industry insulation, sealing, the insulation of protective material, electric heating device, lagging material, the insulation of plant and instrument, electrical heating element and heat insulation material, automobile industry lagging material etc.
Polyethylene terephthalate (English name Polyethylene Terephthalate is called for short PET) is oyster white or polymkeric substance that is light yellow, highly crystalline, and surface smoothing is glossy.PET molecular structure high degree of symmetry, has certain crystalline orientation ability, therefore has higher film-forming properties.PET has good optical property and weathering resistance, and amorphous PET has good optical transparence.PET has excellent abrasion performance, rub resistance and dimensional stability and electrical insulating property in addition.The bottle that PET makes has that intensity is large, the transparency is good, nontoxic, impermeable, quality light, production efficiency advantages of higher, is thus widely used.
PBT is that oyster white is translucent to opaque, crystalline thermoplastic polyester.Its main chain is the saturated line style molecular composition that rigidity phenyl ring and flexible fatty alcohol couple together by each repeating unit, side chain is not had in molecule, symmetrical configuration, the height geometrical regularity of molecule and rigid element make its polymkeric substance have high physical strength, high heat resistance, toughness, resistance to fatigue, self-lubricating, low-friction coefficient, weathering resistance, water-intake rate are low, be only 0.1%, various physical property (comprising electrical property) is still kept in wet environment, electrical insulating property, but volume resistance, dielectric loss are large.Heat-proof water, bases, acids, oils but be subject to halon and corrode, hydrolytic resistance is poor, can crystallization rapidly under low temperature, good forming ability.Shortcoming is that notched Izod impact strength is low, and molding shrinkage is large.Therefore major part adopts glass fiber reinforcement or inorganic fill modification, its tensile strength, flexural strength can be enhanced about more than once, and heat-drawn wire also significantly improves.Can long term operation at 140 DEG C, after fiberglass reinforced, goods vertical, horizontal shrinking percentage is inconsistent, easily makes goods generation warpage.Due to molecular structure and the good over-all properties of PBT uniqueness, and the cost performance of good molding processibility and excellence.
PBT and PET molecular chain structure is similar, and most of character is also the same, and just molecular backbone chain becomes four by two methylene radical, so molecule is submissiveer, processing characteristics is more excellent, but the shaping cycle of PET is longer.PBT, PET being made after alloy can comprehensive the two advantage, and improve the performance of material, domestic at present had more research.But in recent years, electronics, electrically, communication, household electrical appliances, electromechanical equipment to high-performance microization development, more and more higher to the requirement of flame-retardant PBT/PET alloy material, meanwhile, along with the mankind are to the understanding of environmental protection, Green Product is subject to common concern.
The many employings of traditional technology add glass fibre to improve its tensile strength, flexural strength and modulus in engineering resin, but not ideal to the optimization of its resistance toheat, flame retardant properties aspect, can not meet application requiring.Therefore, need further to improve to improve its over-all properties.
