Description

A kind of preparation method of Toughening Modification of Polycarbonate
Technical field
The invention discloses a kind of preparation method of Toughening Modification of Polycarbonate, belong to high polymer material technical field.
Background technology
Polycarbonate (being called for short PC), the features such as polycarbonate has water white transparency, heat-resisting, shock resistance, fire-retardant, all have good mechanical property in common use temperature.At present, three large Application Areass of PC engineering plastics are glazing, automotive industry and electronics, electrical equipment industry, secondly also have office equipment, medical treatment and health care, film, leisure and the protective equipments etc. such as industrial machinery part, CD, packaging, computer.
Wherein, PC prepares scuttlebutt, i.e. bottle blowing grade polycarbonate, is the another important application of polycarbonate.PC bucket is transparent, lightweight, impact-resistance is good, and resistance to certain high temperature and etchant solution washing, use as recoverable container.From 1999 so far, China puts into effect the quality standard of multi-section Regular application bucket, therein defining the use material of scuttlebutt, i.e. PC bucket.
PET, i.e. polyethylene terephthalate are high polymers, by ethylene glycol terephthalate generation dehydration condensation.PET is oyster white or polymkeric substance that is light yellow, highly crystalline, surface smoothing is glossy, in wide temperature range, have excellent physical and mechanical properties, life-time service temperature can reach 120 DEG C, and electrical insulating property is excellent, even under high-temperature high-frequency, its electrical property is still better, shortcoming but corona resistance is poor, creep resistance, resistance to fatigue, rub resistance, dimensional stability are all fine.
PET equally also Zeng Zuowei scuttlebutt uses, afterwards because PET bucket easily produces objectionable impurities when high temperature, react with in weakly acidic pure water, cause the reason of aqueous metamorphism or shortened shelf life, country cancels the material of PET as scuttlebutt gradually, now commercially, the most widely used is PC bucket, i.e. polycarbonate scuttlebutt.Although PC bucket has many advantages, it shows poor in shock strength and toughness properties, brings inconvenience to its use.And output is lower at home due to polycarbonate, relies on import in a large number, cause improving constantly of cost, limit the use of PC on the contrary.
In addition, along with the development of superpolymer field technology, PET, by modification, can reach the quality standard of scuttlebutt, and PET cost is lower.
CN104710749A discloses the patent documentation of one " the high impact modified PC/PET alloy of high strength ", its component by mass percent proportioning is: PC45% ~ 60%, PET15% ~ 30%, toughner 5% ~ 15%, alkali free glass fibre 5% ~ 10%, nano imvite 2% ~ 6%, compatilizer 2% ~ 5%, oxidation inhibitor 0.1% ~ 0.5%, lubricant 0.1% ~ 1%, this alloy material is mainly used in the fields such as household electrical appliances, automobile, component of machine.Restrained by this technical scheme, by PET modification PC, to make PC, there is high strength and high-impact becomes a reality, but first, this scheme is not also suitable for scuttlebutt field, and because the content of PC is too low, other component concentrations are higher, certainly will affect the performance of PC itself, be secondly be unfavorable for prolonged and repeated use; 3rd, resistance to elevated temperatures is poor, uses, can produce toxin for a long time as scuttlebutt, the health of harm people health.
Summary of the invention
The object of the invention is to solve defect in toughness and shock resistance of scuttlebutt polycarbonate and deficiency, mainly by modified PET and modified rigid Nano filling, modification is carried out to polycarbonate and prepare modified polycarbonate.
Technical scheme: a kind of preparation method of Toughening Modification of Polycarbonate, comprises the steps:
The preparation of the 1st step, modified PET: by weight, get polyethylene terephthalate 10 ~ 15 parts, polybutylene terephthalate 2 ~ 5 parts, terephthalic acid 1.5 ~ 2.5 parts, 0.2 ~ 0.6 part, glass fibre, polyimide fiber 0.2 ~ 0.8 part, dioctyl phthalate (DOP) 0.5 ~ 1.2 part and ethylene-vinyl acetate copolymer 0.5 ~ 1.5 part and put into rheometer, after 220 ~ 230 DEG C of melt blendings, cooling, obtains modified PET;
The preparation of the 2nd step, modified rigid Nano filling: by weight, get alumina powder jointed 2 ~ 5 parts, nano imvite 1.5 ~ 3.5 parts, beta-silicon nitride powder 0.5 ~ 1.0 part and white carbon black 1.5 ~ 2.5 parts put into mould, be placed in High Temperature Furnaces Heating Apparatus and carry out High Temperature High Pressure calcining, calcination time 2 ~ 5h, broken after cooling, put into nano-level grinder and be ground to median size 10 ~ 100nm, obtain modified rigid Nano filling;
3rd step, by weight, get polycarbonate 110 ~ 150 parts, modified PET, modified rigid Nano filling, chlorinatedpolyethylene 6 ~ 15 parts, styrene/methacrylic acid methyl terpolymer 5 ~ 12 parts and butyl polyacrylate 6 ~ 15 parts, put into twin screw extruder, melt blending aftershaping.
