Abstract
The invention belongs to polymer composite processing technique fields, more particularly to one kind from capacity increasing modifying PET/PC alloy and preparation method thereof, which includes following component in parts by weight: 50-70 parts of PC resin, 0.3-0.8 parts of antioxidant 1010,1-10 parts of toughener, 0.5-1.5 parts of stabilizer, 30-50 parts of modified PET resin.Of the invention is a kind of from capacity increasing modifying PET/PC alloy and preparation method thereof, the alloy material of preparation had both had the rigidity and heat resistance of PC resin, again with the solvent resistance of PET resin, the aromatic ester branched structure of modified PET is conducive to improve the interface compatibility of resin, improve alloy material to notch sensitivity, notch impact toughness is obviously improved, and stabilizer can effectively inhibit the transesterification under high temperature, improves the high-temperature stability of resin；The advantages of of the invention is low in cost, and process is simple, continuous, high production efficiency, environmental friendly pollution-free, stable product quality, has preferable practical function and economic benefit.
Description
Technical field
The invention belongs to polymer composite processing technique fields, and in particular to a kind of from capacity increasing modifying PET/PC alloy
And preparation method thereof.
Background technique
Polyethylene terephthalate (abbreviation PET) is exchanged with glycol ester by dimethyl terephthalate (DMT) or to benzene two
Formic acid and ethylene glycol esterification first synthesize bishydroxyethyl terephthalate, then carry out polycondensation reaction again and are made.PET plastic molecule knot
Structure high degree of symmetry has certain crystalline orientation ability, so film forming with higher and become second nature.PET plastic has fine
Optical property and weatherability, amorphous PET plastic have good optical transparence.In addition PET plastic has excellent
Abrasion performance frictional property and dimensional stability and electrical insulating property.
Polycarbonate (abbreviation PC) is the high molecular polymer in strand containing carbonate group, can according to the structure of ester group
It is divided into the multiple types such as aliphatic, aromatic series, aliphatic-aromatic.Wherein due to aliphatic and the poly- carbonic acid of aliphatic-aromatic
The mechanical performance of ester is lower, to limit its application in terms of engineering plastics.Only have what aromatic copolycarbonate obtained at present
Industrialized production.Due to the particularity on polycarbonate structure, it is most fast growth rate in five large-engineering plastics has been become
General engineering plastic.PC (polycarbonate) has the excellent transparency, impact resistance, electrical insulation capability, dimensional stability, resistance to
Combustibility etc., but its that there are melt viscosities is high, is easy the disadvantages of stress cracking；PET long-term use temperature is up to 120 degree, electricity
Insulating properties is excellent, or even under high-temperature high-frequency, electrical property is still preferable, but corona resistance is poor, creep resistance, fatigue durability,
Dimensional stability is all fine, and PET (polyethylene terephthalate), which is added, can improve the anti-stress cracking of PC, improves PC
Processing fluidity, make it have good processing performance.The advantages of PC/PET alloy material has both PC and PET concurrently.
PC/PET alloy is a kind of engineering plastics haveing excellent performance, and be can be used in many occasions, such as applied to electronics

Polymer, PET are crystalline polymers, and PC/PET alloy belongs to typical amorphous/crystalline co-mixing system, and the compatibility of the two is not
It is good.Third component is added in PC/PET alloy system, the compatibility of both PC and PET in system, Er Qiesui can be significantly improved
The continuous development application of PC/PET alloy, the requirement of functionalization, high performance proposed to PC/PET alloy, but it is many when
It waits the selection for third component to need to take a substantial amount of time to can be only achieved desired effect, and with the extension of time, very
More third components are not easy high temperature resistant in process and are easy the problem of being precipitated, and therefore, it is total how to further increase PET/PC
The compatibility for mixing gold, is an important research direction to improve its comprehensive performance, while being also beneficial to expand PC/PET
The application field of alloy material.
