Description
Technical field：
The present invention relates to technical field of polymer materials more particularly to a kind of HI high impact to enhance polyethylene naphthalate
Composite material.
Background technology：
Polyethylene naphthalate is poly- (2,6-naphthalenedicarboxylic acid glycol ester), and abbreviation PEN is a kind of novel thermoplastic
Property polyester, the structure of PEN resins is similar to PET, it with naphthalene nucleus replace PET in phenyl ring.The properties almost all of PEN is excellent
In PET, there are many excellent performances.The fusing point of PEN is 256 DEG C, close with PET, and glass transition temperature is 118 DEG C, than PET high
Go out 40 DEG C or more, temperature is used for a long time at 155 DEG C or more, product size is stablized, and percent thermal shrinkage is less than PET, PA etc..EN has excellent
Good mechanical property.The tensile strength ratio PET high about 35% of PEN, and the stable mechanical property of PEN, even if in high temperature, high humidity
In the case of degree, elasticity modulus, intensity, creep and service life can still keep relative stability.
The feature that polyethylene naphthalate protrudes is that gas barrier property is good, and the air-tightness of the film of same thickness, PEN is far above
General-purpose plastics polyethylene, polypropylene, polystyrene, also above the engineering plastics such as polyamide, PPS, PET.Experiment shows PEN pairs
4 times of the barrier property ratio PET high of O2, it is 5 times high to the barrier property of CO2, it is 3.5 times high to the barrier property of vapor.
The chemical stability of polyethylene naphthalate is excellent.Ester group in its strand is met water and can be decomposed, but its water
It is only the 1/4 of PET to solve speed.PEN stablizes organic solvent, and acid and alkali resistance ability is better than PET, just because of poly- naphthalenedicarboxylic acid second
Diol ester has the performances such as excellent heat-resisting, barrier properties for gases, is widely used in the industries such as packing film and container.
With the continuous expansion of the purposes of polyethylene naphthalate material, especially in electronic apparatus, machinery zero
Application on part, product require material to have higher performance, the performance of polyethylene naphthalate resin material can not meet
It is required that, therefore it is required that developing the composite material of the polyethylene naphthalate of higher performance.
Invention content：
The purpose of the present invention is for disadvantage present on the prior art, HI high impact is carried out to polyethylene naphthalate
Enhancing is modified, and provides a kind of polyethylene naphthalate composite material with high intensity, high rigidity, high tenacity.
The technical solution adopted in the present invention has：A kind of HI high impact enhancing polyethylene naphthalate composite material, institute
State nanocomposite constituents is by weight percentage：
Polyethylene naphthalate 55~80%,
Toughener 3~10%,
Glass fibre 10~40%,
Processing aid 0.3~3%.
Further, the polyethylene naphthalate is poly- (2,6-naphthalenedicarboxylic acid glycol ester).
Further, the glass fibre is chopped glass fiber, and length is 3~10mm, and filament diameter is 5~15um.
Further, the toughener is the copolymer or ethylene-acrylic acid of ethylene-methyl methacrylate glycidol fat
Methyl esters-glycidyl methacrylate random terpolymer.
Further, the processing aid be plasticizer, stabilizer, releasing agent, dyestuff, pigment, one kind in filler or
Several mixtures.
The present invention has the advantages that：The present invention changes to carrying out HI high impact enhancing to polyethylene naphthalate
Property, a kind of performance of HI high impact of the invention enhancing polyethylene naphthalate composite material is significantly improved.
Specific implementation mode：
In order to achieve the goal above, the technical solution of the present invention is to provide a kind of HI high impacts to enhance poly- naphthalenedicarboxylic acid ethylene glycol
Ester composite material, it is characterised in that：It includes that the raw material of following weight percent proportioning is made：
Polyethylene naphthalate 55~80%,
Toughener 3~10%,
Glass fibre 10~40%,
Processing aid 0.5~3%.
Wherein polyethylene naphthalate is poly- (2,6- (ethylene naphthalate)s).
Wherein toughener is the copolymer or ethylene-methyl acrylate-first of ethylene-methyl methacrylate ethylene oxidic ester
Base glycidyl acrylate random terpolymer.
Wherein glass fibre is chopped strand, and preferred length is 3~10mm, and filament diameter is 5~15um.
It can also further contain it in a kind of HI high impact enhancing polyethylene naphthalate composite material of the present invention
Its processing aid, such as plasticizer, stabilizer, releasing agent, filler, dyestuff, pigment and other resins for assigning other characteristics, only
Otherwise damage the effect of the present invention.
The present invention a kind of HI high impact enhancing polyethylene naphthalate composite material preparation method not especially by
Limit, a kind of HI high impact of the invention enhances polyethylene naphthalate composite material can be by with such as extruder (single spiral shell
Bar or double screw extruder), hot rolling, kneader, the kneading such as kneading machine and prepare, in these, from the angle of production efficiency
For, blend preferably is prepared with single screw rod or double screw extruder, the temperature of extrusion is usually 240-300 DEG C, preferably
250-280℃.The sequence of each component for mixing the present invention is typically not critical, can by those skilled in the art Lai
It determines.
The present invention will be described in further detail in following embodiments, but the present invention should not be limited by these embodiments
System.
