Abstract
The invention discloses a kind of anti-aging PA-ABS plastic alloy, be made up of by weight following component: 20-30 part PA, 70-80 part ABS, 2-4 part compatilizer, 0.5-1.5 part antiaging agent.Anti-aging PA-ABS plastic alloy of the present invention, good mechanical performance, especially shock strength is high, and has outstanding heat aging performance, uses under being adapted at thermal extremes environment.
Description
Technical field
The present invention relates to a kind of polyblend, particularly relate to a kind of anti-aging PA-ABS 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.
Polymeric amide (PA is commonly called as nylon) is the resin that DuPont develops at first for fiber, realizes industrialization in nineteen thirty-nine.Start development and production injection-molded item the 1950's, the requirement meet the lightweight of downstream industry goods with substituted metal, reducing costs.PA has good over-all properties, comprise mechanical property, thermotolerance, wearability, chemical proofing and self lubricity, and frictional coefficient is low, there is certain flame retardant resistance, be easy to processing, be suitable for, by glass fibre and other filler filling enhancing modified, improving performance and broadened application scope.
PA-ABS plastic alloy, uses in automotive trim as structural component, is the practical substitute of current material, meanwhile, also very tempting from cost angle.This material can not only meet the harsh specification requirements of design change aspect, also significantly can save system cost simultaneously.
But current PA-ABS 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 PA-ABS 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 PA-ABS plastic alloy, is made up of by weight following component: 20-30 part PA, 70-80 part ABS, 2-4 part compatilizer, 0.5-1.5 part antiaging agent.
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 POE-g-MAH, 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 PA-ABS 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 PA-ABS 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 160-220 DEG C of temperature, namely obtains described anti-aging PA-ABS 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 PA-ABS plastic alloy of the present invention, good mechanical performance, especially shock strength is high, and has outstanding heat aging performance, uses under being adapted at thermal extremes environment.
