Though there are many researchists all being engaged in the composition modified research of polycarbonate/ABS both at home and abroad, polycarbonate/every performance of ABS composition still can not satisfy the requirement of premium quality product fully at present.
Summary of the invention
The object of the present invention is to provide a kind of polycarbonate/ABS composition, said composition has excellent flowability energy, splendid impact property and processing characteristics, can be particularly suitable for the production of thin-wall product directly as the starting material of handset shell, various household electrical appliances parts.
A further object of the present invention is to provide the purposes of a kind of polycarbonate/ABS composition.
In order to realize the object of the invention, a kind of polycarbonate of the present invention/ABS composition comprises 20～90 parts of polycarbonate (PC), 72～8 parts of ABS, 8～2 parts of compatilizers, 0.4～0.2 part in oxidation inhibitor, 0.3～0.1 part of lubricant.
Preferably, 40～90 parts of polycarbonate, 50～10 parts of ABS, 6～2 parts of compatilizers, 0.4～0.2 part in oxidation inhibitor, 0.3～0.1 part of lubricant.
Be more preferably 65～85 parts of polycarbonate, 32～12 parts of ABS, 5～3 parts of compatilizers, 0.4～0.2 part in oxidation inhibitor, 0.3～0.1 part of lubricant.
Described part is weight part, can be this areas such as kilogram, gram, ton, jin weight unit commonly used.
Wherein, polycarbonate is a dihydroxyphenyl propane class polycarbonate, and melting index is 5～15g/10min, and as external BAYER, all there is production in GE, Supreme Being people company such as change into.
ABS is the multipolymer of vinylbenzene, divinyl, vinyl cyanide, and the present invention selects butadiene content between 30%～70%, is preferably 40%～60%, selects high-load divinyl can improve the modulus of composition, to satisfy the requirement of electric equipment products.
For light, thermal stability and the processing stability that improves product, add some oxidation inhibitor at composition, oxidation inhibitor can be selected oxidation inhibitor such as organic Hinered phenols, amine, phosphorous acid esters, thioesters class, can be one or more mixing, blending ratio is 1～2: 1～2 or 1～2: 1～2: 1～2; Hinered phenols can be four [β-(3,5-di-t-butyl-4-hydroxyl-phenyl) propionic acid] pentaerythritol ester (abbreviation antioxidant 1010), β-(4-hydroxyl-3, the 5-di-tert-butyl-phenyl) the positive octadecanol ester of propionic acid (abbreviation antioxidant 1076), N, N '-, 6-dihexyl two (3,5-two (1,1 dimethyl ethyl)-4-hydroxybenzene propionyl (being called for short oxidation inhibitor 1098), 3,5-two (1,1 dimethyl ethyl)-and 4-hydroxy phenylpropionic acid 2-(3,5-two (1,1 dimethyl ethyl)-4-hydroxy phenyl)-1-oxopropyl) hydrazides (being called for short oxidation inhibitor MD1024), 1,3,5-trimethylammonium-2,4,6-three (3, the 5-di-tert-butyl-4-hydroxyl benzyl) benzene (abbreviation antioxidant 330), 4,4 '-thiobis (the 6-tertiary butyl-3-methylphenol) (abbreviation antioxidant 300) etc., amine should be on-contaminated Ursol D system, as N-phenylaniline and 2,2, the reaction product of 4-2,4,4-Trimethyl-1-pentene; Phosphorous acid esters can be triphenyl phosphite (TPP), three-(nonyl phenyl) phosphorous acid ester (TNPP), three (2, the 4-di-tert-butyl-phenyl) phosphorous acid ester (being called for short oxidation inhibitor 168), tetramethylolmethane diphosphite two (18) alcohol ester (being called for short oxidation inhibitor 619), tetramethylolmethane diphosphite two (2,4-di-tert-butyl phenyl) ester (be called for short oxidation inhibitor 626) etc., the thioesters class can be Tyox B DLTP or thio-2 acid two (18) ester DSTP etc.
For the ease of processing modified finishing smoothly, just be convenient to extruding of twin screw, can in composition, add lubricant, described lubricant is selected stearic acid stearyl ester class or oxidized polyolefin waxes for use, stearic acid stearyl ester class is stearic acid pentaerythritol ester or montanate, oxidized polyolefin waxes is PE wax or PP wax, preferably stearic acid stearyl ester class.
Generally, when the ABS blending and modifying, often select the ABS of butadiene content about 18% for use, because along with the increase of divinyl content in ABS, the consistency of polycarbonate and ABS system is just poor more; Researchist of the present invention finds in process of the test, as long as choose suitable compatilizer, can solve the contradiction between the high butadiene content among consistency and the ABS fully.
Compatilizer of the present invention is non-response type compatilizer, grafts such as acrylonitritrile-styrene resin and grafts such as divinyl, second third glue or vinylformic acid etc., this kind compatilizer can satisfy the needs of composition system fully, has improved the consistency between PC and the ABS.
