Description
Technical field
The present invention relates to engineering plastics technical field, glass fiber reinforcement PET/ABS resin combination being specifically related to a kind of high fluidity and preparation method thereof.
Background technology
Conventional polybutylene terephthalate (PBT) (PET) is the engineering plastics of a kind of hemicrystalline, and it has good mechanical property, electrical property, thermostability and chemical resistance etc., is widely used in the industries such as automobile, electronics, electrical equipment；Also in polyester bottles, fiber, the field such as thin film is widely used.But at injection molding art, owing to PET resin can crystallize in melting process, its crystallisation by cooling speed is relatively slow, and cool time is longer, limits its application.
By introducing copolymerization units in polymerization process, it is possible to reduce the cold crystallization of PET and crystallizing power, even synthesizing the PET resin of amorphous, this resin has relatively low fusing point.As patent CN103102473 A discloses a kind of by introducing 10-30% M-phthalic acid, the crystallization modifier of 5-29% and the branched regulator of 0.03-2%, low melting point, transparent PET resin are finally synthesized.Patent CN 103102646 A discloses a kind of fusing point regulator by introducing 5-10% and the crystallization promoter of 7-20%, has synthesized a kind of low melting point, the PET resin of high crystallization temperature.And patent CN 104987498 A discloses a kind of by introducing 2-methyl isophthalic acid, ammediol (MPO) and M-phthalic acid, having synthesized PTT and the polyethylene terephthalate of low melting point, its melting range is between 190 DEG C to 250 DEG C.
Copolyester with low melting point application currently mainly is textile industry, and it can carry out composite spinning with conventional polyester, and the core-skin composite fiber of gained can be used for and wool blended the worn performance improving worsted fabric；And copolyester with low melting point also has wide application prospect in non-woven fabrics, hot-melt prepreg machine, building materials and paint field.
PET is Crystalline plastics, and ABS is non-Crystalline plastics, notable difference is all there is in both in terms of crystal habit and solubility parameter, currently mainly rely on and select suitable compatilizer, improve the adhesion of two kinds of system boundaries, improve the morphological stability of blend, mechanical property and processing characteristics, meanwhile, overcome the shortcoming bigger to processing conditions degree of dependence that binary blend morphosis instability is caused.Utilize low-melting point PET resin for improving the processability of PET/ABS alloy, compared to traditional PET and ABS compositions, significant advantage can be had in terms of processing fluidity in order to avoid compatilizer selects the problem of aspect, particularly fiberglass reinforced PET/ABS alloy, the advantage of its mobility is more aobvious prominent.Therefore, this patent develops the glass fiber reinforcement PET/ABS resin alloy of high fluidity, can solve current fiberglass reinforced PET/ABS alloy problem in terms of injection.
