Description
Technical field
The present invention relates to a kind of polyblend, particularly relate to a kind of anti-aging PC-PBT polyblend.
Background technology
Polycarbonate, is called for short PC, and be the high molecular polymer containing carbonate group in molecular chain, the structure according to ester group can be divided into the broad varietys such as aliphatics, aromatic series, aliphatic-aromatic.Mechanical property wherein due to aliphatics and aliphatic-aromatic polycarbonate is lower, thus limits its application in engineering plastics.The suitability for industrialized production at present only having aromatic copolycarbonate to obtain.Due to the singularity on polycarbonate structure, now become the general engineering plastic that in five large-engineering plastics, rate of growth is the fastest.
Polybutylene terephthalate, English name: polybutyleneterephthalate, be called for short PBT, belong to polyester series, be formed by 1.4-pbt butyleneglycol (1.4-Butyleneglycol) and terephthalic acid (PTA) or terephthalate (DMT) polycondensation, and the oyster white made via mixing program is translucent to opaque, crystalline thermoplastic polyester's resin.Thermoplastic polyester is referred to as together with PET, or saturated polyester.
The advantage of PC is that room temperature is firm and tough, but when high temperature, thermal distortion is serious.Shortcoming is stress cracking, and viscosity is large; The advantage of PBT be its rigidity by the impact of temperature, be out of shape little; Namely material PC-PBT after blended like this remains both advantage.
PC-PBT polyblend has higher surface hardness, higher rigidity and toughness, also has the ability of higher high temperature resistance shape, also has higher anti-stress cracking ability; Its mechanical property falls between.
But current PC-PBT polyblend ageing resistance is not good.
Summary of the invention
For above shortcomings in prior art, technical problem to be solved by this invention is to provide a kind of anti-aging PC-PBT polyblend, has good ageing resistance.
Technical problem to be solved by this invention is achieved by the following technical solution:
A kind of anti-aging PC-PBT polyblend, is made up of by weight following component: 100 parts of PC, 20-40 part PBT, 4-8 part compatilizers, 0.5-1.5 part antiaging agents.
Described antiaging agent, be made up of by weight following component: 30-50 part 4, the two octadecyl of 4 '-thiobis (the 6-tertiary butyl-3-methylphenol), 30-50 part 1,1,3-tri-(2-methyl-4-hydroxyl-5-trimethylphenylmethane base) butane, 10-30 part thio-2 acid.
4,4 '-thiobis (the 6-tertiary butyl-3-methylphenol), No. CAS: 96-69-5, English name: 4,4'-Thio-bis (6-tert-butyl-m-methylphenol).
1,1,3-tri-(2-methyl-4-hydroxyl-5-trimethylphenylmethane base) butane, No. CAS: 1843-03-4,4,4', 4''-(1-methyl-1-propanyl-3-ylidene) tris [2-(1,1-dimethylethyl)-5-methyl-Phenol.
The two octadecyl of thio-2 acid, English name: Distearylthiodipropionate, No. CAS: 693-36-7.
Two to 4,4 '-thiobis (the 6-tertiary butyl-3-methylphenol), 1,1,3-tri-(2-methyl-4-hydroxyl-5-trimethylphenylmethane base) butane and thio-2 acid octadecyl is uniformly mixed, this antiaging agent can be obtained.
Described compatilizer is EBA-GMA, PP-g-MA, PP-g-AA, EAA, PS-g-PMMA, PS-g-MAH, PP-g-Pa6, PS-b-PMMA, PS-b-PBA, PE-g-ST, PP-g-ST, ABS-g-MAH, PP-g-MAH, EVA, SEBS, SEBS-g-MAH or PE-g-MAH.
Industry universal method can be adopted to be prepared anti-aging PC-PBT polyblend of the present invention, and such as: take each component by proportioning, after mixing, melting mixing, extruding pelletization, namely obtain described anti-aging PC-PBT polyblend.
Concrete, can for take each component by proportioning, in mixing machine, control rotating speed under room temperature at 300-400 rev/min, mixing 5-10 minute, proceeds to after taking-up in screw extrusion press, extruding pelletization at 230-260 DEG C of temperature, namely obtains described anti-aging PC-PBT polyblend.
Obviously, in the present invention for improving other performances of product, other auxiliary agents can also be added adaptively, as fire retardant, tinting material and static inhibitor etc.
Contriver is drawn by great many of experiments, by 4,4 '-thiobis (the 6-tertiary butyl-3-methylphenol), 1,1,3-tri-(2-methyl-4-hydroxyl-5-trimethylphenylmethane base) butane and the two octadecyl three kinds of antiaging agents of thio-2 acid carry out reasonable composite use, synergy, antiageing effect is obvious.
PC-PBT polyblend good heat resistance of the present invention, stress crack resistant, have excellent wear-resisting, chemical resistance, low temperature impact strength is high, easily processing and covering with paint property good, be mainly used in high-grade car collision bumper, car bottom plate, panel and motorcycle guard board etc.PC-PBT polyblend of the present invention also has outstanding heat aging performance, uses under being adapted at thermal extremes environment.
