Description
Technical field
The present invention relates to engineering plastics technical field, PET engineering plastics particularly relating to a kind of easy-formation and preparation method thereof.
Background technology
The widespread use of plastics plays a very important role electric and electronic industrial expansion.Plastics have excellent electrical insulation capability, and the feature such as quality is light, physicochemical property stable, easy-formation processing, cost are low, are widely used as the case material of electric/electronic device and components and parts, coating material, substrate material, dielectric insulation layer material etc.In addition, in recent years along with the development of science and technology, there is plastics and the matrix material thereof of the functions such as conduction, magnetic conduction, electromagnetic shielding, also the electric and electronic material that some are traditional is replaced just gradually, widen the range of application of plastics in electric and electronic industry further, and create huge economic and social benefit.
To various different electrical and electronic product, specifically should consider from aspects such as the service requirements of product, forming process and economy and select suitable material.As the plastics that electrical and electronic product insulating material uses, electrical insulation properties (volume specific resistance, surface resistivity) and the dielectric properties (specific inductivity, dielectric loss angular factor, dielectric strength) of material mainly should be considered.Insulation engineering plastics must have high resistivity, high dielectric strength, low-k, low dielectric loss angle tangent.Various plastics are due to the difference of structure, and electrical property has very big-difference.Except electrical property, also should consider the mechanical property (intensity, modulus, elongation, hardness, wear resistance, resistance to tearing, resistance to flexing, fatigue resistance) of material, thermotolerance, ageing resistance, lower temperature resistance, radiation resistance (resistance to electron rays, gamma-rays, neutron ray), flame retardant resistance, chemical stability (erosion resistance, organic solvent resistance, wet fastness), cementability, foreign matter content etc.
When engineering plastics are for making various electric elements, for ensureing the trouble-free service of electrical equipment, require that engineering plastics have good thermotolerance.PET (polyethylene terephthalate) is important member in linear thermoplastic's polyester family.It is transparent, glossiness is high, have good weathering resistance and chemical stability, good rigidly, and thermotolerance is high, can keep excellent mechanical property in wide temperature range.PET can adopt various moulding process to be processed into goods.But because in PET main chain, oxyethyl group segment is short, its phenyl ring be connected is higher to its steric effect, and in PET crystallisation process, relate to the configuration inversion of main chain quaternary carbon atom, this process need be higher with energy, make the crystallisation process of PET resin slow, cause the problems such as injection mould temperature higher (more than 80 DEG C), molding cycle long, the easy sticking to mould of goods further, the application in engineering plastics is limited, is mainly used in fiber, bottle material and film at present.Although the basic property of PET resin is good, but there is the problems such as melt strength difference, crystallization velocity be slow, show as in PET resin melt process and very easily occur melt " trickling phenomenon ", after there is the PET resin cooling of " trickling phenomenon ", material property is low, is difficult to use as engineering plastics.Modification difficult point when PET resin is applied as engineering plastics and key improve its crystallization rate and crystallization degree, improve melt strength simultaneously, control the melt viscosity stability in preparation and fabrication process, the PET engineering plastics dimensional stability of preparation is poor, produce be full of cracks and slowly shaping, resistance to impact shock and chemical resistance poor, meanwhile, the shrinking percentage of goods, warpage and rate of moisture absorption are all higher.
Summary of the invention
In view of this, one aspect of the present invention provides a kind of PET engineering plastics of easy-formation, this PET engineering plastics dimensional stabilizing, easy-formation and can rapid shaping, goods not easily produce be full of cracks, have good resistance to impact shock and chemical resistance, meanwhile, the shrinking percentage of goods, warpage and rate of moisture absorption is reduced.
