Description
Technical field
The present invention relates to a kind of polyblend, particularly relate to a kind of anti-aging ABS-TPU plastic alloy.
Background technology
ABS resin (acrylonitrile-butadiene-styrene copolymer, ABS is the acronym of AcrylonitrileButadieneStyrene) is that a kind of intensity is high, good toughness, be easy to thermoplastics type's Polymer Materials ' Structure of machine-shaping.
ABS is the general thermoplastic engineering plastic grown up 1940's, it is the very outstanding plastics variety of a comprehensive mechanical property, not only there is good rigidity, hardness and processing fluidity, and there is high tenacity feature, can injection moulding, extrude or thermoforming.
Polyurethane Thermoplastic Elastomer, Thermoplasticpolyurethane, is called for short TPU.
But current ABS-TPU plastic alloy 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 ABS-TPU plastic alloy, has good ageing resistance.
Technical problem to be solved by this invention is achieved by the following technical solution:
A kind of anti-aging ABS-TPU plastic alloy, is made up of by weight following component: 100 parts of ABS, 15-25 part TPU, 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.
Industry universal method can be adopted to be prepared anti-aging ABS-TPU plastic alloy of the present invention, and such as: take each component by proportioning, after mixing, melting mixing, extruding pelletization, namely obtain described anti-aging ABS-TPU plastic alloy.
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 180-190 DEG C of temperature, namely obtains described anti-aging ABS-TPU plastic alloy.
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.
Anti-aging ABS-TPU plastic alloy of the present invention can significantly improve the stress cracking resistance of TPU, and can improve it to oxygen, ozone, ultraviolet stability, and can improve shock-resistance, wearability, the molding processibility of ABS.Can be used for producing automobile component, belt pulley, low load gear and packing ring, and there is outstanding heat aging performance, use under being adapted at thermal extremes environment.
