Description
Technical field：
The present invention relates to technical field of polymer materials more particularly to a kind of fiberglass reinforced polyethylene naphthalate are multiple
Condensation 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,
There are the performances such as excellent heat-resisting, barrier properties for gases just because of polyethylene naphthalate, be widely used in wrapping
Fill the industries such as 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, glass increasing is carried out to polyethylene naphthalate
It is strong modified, provide a kind of polyethylene naphthalate composite material with high intensity, high rigidity.
The technical solution adopted in the present invention has：A kind of fiberglass reinforced polyethylene naphthalate composite material, it is described
Nanocomposite constituents are by weight percentage：
Polyethylene naphthalate 55~80%,
Glass fibre 20~40%,
Processing aid 0.3~3%.
Further, the polyethylene naphthalate is poly- (2,6-naphthalenedicarboxylic acid glycol ester).
Further, the glass fibre is chopped strand, and length is 3~10mm, and filament diameter is 5~15um.
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 is changed by carrying out fiberglass reinforced to polyethylene naphthalate
Property, the performance of fiberglass reinforced polyethylene naphthalate composite material of the invention 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 fiberglass reinforced polyethylene naphthalate
Composite material, it includes that the raw material of following weight percent proportioning is made：
Polyethylene naphthalate 57~80%,
Glass fibre 20~40%,
Processing aid 0.5~3%.
Wherein polyethylene naphthalate is poly- (2,6- (ethylene naphthalate)s).
Wherein glass fibre is chopped strand, and preferred length is 3~10mm, and filament diameter is 5~15um.
Other add can also further be contained in the fiberglass reinforced polyethylene naphthalate composite material of the present invention
Work auxiliary agent, such as plasticizer, stabilizer, releasing agent, filler, dyestuff, pigment and other resins for assigning other characteristics, as long as not damaging
The effect of the evil present invention.
The preparation method of the fiberglass reinforced polyethylene naphthalate composite material of the present invention is not particularly limited, this hair
Bright fiberglass reinforced polyethylene naphthalate composite material can be by with such as extruder (single screw rod or twin-screw extrusion
Machine), hot rolling, kneader, kneading machine etc. mediate and prepare, in these, from the perspective of production efficiency, preferably with list spiral shell
Bar or double screw extruder prepare blend, and the temperature of extrusion is usually 240-300 DEG C, preferably 250-280 DEG C.Mix this hair
The sequence of bright each component is typically not critical, and can be determined by those skilled in the art.
The present invention will be described in further detail in following embodiments, but the present invention should not be limited by these embodiments
System.
Compound prepared by each embodiment is molded into the standard batten of test, the physics in each embodiment by standard size
Performance is tested by international standard respectively.
The present invention is verified by following example：
Polyethylene naphthalate：PEN, Japanese Di Ren companies.
Glass fibre：ECS11-03-534, the production of Chinese glass megalith group；
Antioxidant：Antioxidant 1076 is produced by German BASF；
Releasing agent：PETS is produced by Shanghai Lang Te companies.
The present invention is verified by following example, and detailed data result see the table below：
Embodiment 1-4 formula tables and performance test results
Can significantly it be found out by the experimental result of examples detailed above, fiberglass reinforced polyethylene naphthalate of the invention
The performance of composite material is significantly improved.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as the present invention's
Protection domain.
