The anti-aging PA-PC plastic alloy provided by the invention has excellent thermal aging resistance, and can be applied under extreme-high-temperature environments.
Description
Technical field
The present invention relates to a kind of polyblend, relate in particular to a kind of anti-aging PA-PC polyblend.
Background technology
Polycarbonate (be called for short PC) is the high molecular polymer that contains carbonate group in the molecular chain, can be divided into the broad varietys such as aliphatics, aromatic series, aliphatic-aromatic according to the structure of ester group.Wherein the mechanical property owing to aliphatics and aliphatic-aromatic polycarbonate is lower, thereby has limited its application aspect engineering plastics.Only have at present that aromatic copolycarbonate obtains suitability for industrialized production.Because the singularity on the polycarbonate structure has now become the fastest general engineering plastic of rate of growth in the five large-engineering plastics.
Polymeric amide (PA is commonly called as nylon) is that U.S. DuPont company develops the resin for fiber at first, realizes industrialization in nineteen thirty-nine.Begin the development and production injection-molded item the 1950's, satisfy the requirement of the lightweight of downstream industry goods, reduction cost with substituted metal.PA has good over-all properties, comprise mechanical property, thermotolerance, wearability, chemical proofing and self lubricity, and frictional coefficient is low, certain flame retardant resistance is arranged, be easy to processing, be suitable for improving performance and broadened application scope with glass fibre and other filler filling enhancing modified.
The PA-PC polyblend, impact property is better, can be widely used on automotive interior parts, business machine, the communication apparatus, electrical home appliances and the set lights.
Yet present PA-PC polyblend ageing resistance is not good.
Summary of the invention
For above shortcomings in the prior art, technical problem to be solved by this invention provides a kind of anti-aging PA-PC 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 PA-PC polyblend is made of by weight following component: 30-50 part PA, 50-70 part PC, 4-10 part compatilizer, 0.5-1.5 part antiaging agent.
Described antiaging agent, formed by weight by following component: 30-50 part 4,4 '-thiobis (the 6-tertiary butyl-3-methylphenol), 30-50 part 1,1,3-three (2-methyl-4-hydroxyl-5-trimethylphenylmethane base) butane, the two stearyl alcohol esters of 10-30 part thio-2 acid.
4,4 '-thiobis (the 6-tertiary butyl-3-methylphenol), CAS number: 96-69-5, English name: 4,4'-Thio-bis (6-tert-butyl-m-methyl phenol).
1,1,3-three (2-methyl-4-hydroxyl-5-trimethylphenylmethane base) butane, CAS number: 1843-03-4,4,4', 4''-(1-methyl-1-propanyl-3-ylidene) tris[2-(1,1-dimethylethyl)-5-methyl-Phenol.
The two stearyl alcohol esters of thio-2 acid, English name: Distearyl thiodipropionate, CAS number: 693-36-7.
With 4,4 '-thiobis (the 6-tertiary butyl-3-methylphenol), 1,1, the two stearyl alcohol esters of 3-three (2-methyl-4-hydroxyl-5-trimethylphenylmethane base) butane and thio-2 acid mix, and can make this antiaging agent.
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.
Can adopt industry universal method to be prepared anti-aging PA-PC polyblend of the present invention, for example: take by weighing each component by proportioning, after mixing, melting mixing, extruding pelletization namely obtain described anti-aging PA-PC polyblend.
Concrete, can be for take by weighing each component by proportioning, in mixing machine, the control rotating speed mixed 5-10 minute at 300-400 rev/min under the room temperature, changed in the screw extrusion press after the taking-up, extruding pelletization under 140-150 ℃ of temperature namely obtains described anti-aging PA-PC polyblend.
Obviously, for improving other performances of product, can also add adaptively other auxiliary agents, such as fire retardant, tinting material and static inhibitor etc. in the present invention.
The contriver draws by great many of experiments, with 4,4 '-thiobis (the 6-tertiary butyl-3-methylphenol), 1,1, the two three kinds of antiaging agents of stearyl alcohol ester of 3-three (2-methyl-4-hydroxyl-5-trimethylphenylmethane base) butane and thio-2 acid carry out reasonable composite use, synergy, antiageing effect is obvious.
Anti-aging PA-PC polyblend of the present invention, the adding of PA can improve resistance, stress cracking resistance and the processing characteristics of PC, reduces the cost of PC, keeps simultaneously the higher thermotolerance of PC and shock-resistance.Anti-aging PA-PC polyblend of the present invention also has outstanding heat aging performance, is adapted at using under the thermal extremes environment.
