Abstract
The invention discloses a thermoplastic elastomer shot sticky with ABS (acrylonitrile butadiene styrene). The thermoplastic elastomer is characterized by being prepared from the following raw material components by weight percent: 0-40% of hydrogenated styrene-butadiene-styrene block copolymer, 20-60% of styrene-butadiene-styrene block copolymer, 2-20% of styrene-butadiene copolymer, 15-50% of mineral oil, 0.1-1% of antioxidant, and 0.1-1% of processing aid. The thermoplastic elastomer has the advantages that the styrene-butadiene copolymer is used for replacing an adhesive and a polar compatilizer, and the transparency of the thermoplastic elastomer is greatly improved while the necessary binding effect and the tensile strength are ensured.
Description
Technical field
The present invention relates to a kind of macromolecular material, especially relate to a kind of and ABS and penetrate sticking thermoplastic elastomer.
Background technology
The product of being processed by the ABS material at present is often harder and smooth; For texture and the feel that strengthens product surface; The thermoplastic elastomer that normally will penetrate sticking ABS is compounded in the surface of ABS finished product through coating technology; Not only make product surface be full of soft feeling; Can also increase product functionality and added value, like noise abatement, damping, waterproof, crashproof, anti-skidding and comfort etc.For this reason; People pair penetrate sticking thermoplastic elastomer with ABS and have carried out many-sided development; Application number is No. 200810066132.9 Chinese invention patent application " a kind of being used for penetrated sticking thermoplastic elastomer with ABS low temperature "; Introduced a kind of prescription that is used for penetrating sticking thermoplastic elastomer and constituted with ABS, this patent with ABS penetrate sticking thermoplastic elastomer have adjustable durometer level high, can penetrate characteristics sticking and that adhesive effect is good, elasticity is high with ABS low temperature.Application number is the Chinese invention patent application " a kind of being used for penetrated sticking hot plastomer's elastomerics with ABS " of 201010166524.X; But introduced the hardness that free adjustment is penetrated sticking ABS thermoplastic elastomer; Make snappiness and high, surface effect good thermoplastic elastomerics with the bonding strength of ABS material.But on some certain products; Usually can require to penetrate sticking thermoplastic elastomer and have good transparency; And the problem that above-mentioned product exists is in order to make product have good bonding force; Admixture caking agent and polarity compatible agent; Therefore transparency of products is very low, can not obtain transparency preferably even do not add mineral filler.
Summary of the invention
Technical problem to be solved by this invention provide a kind of have a higher clarity penetrate sticking thermoplastic elastomer with ABS.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of and ABS penetrates sticking thermoplastic elastomer, comprises the following weight percentages component:
Described mineral oil is that flash-point is higher than 200 ℃ naphthenic oil.
Described processing aid is to be selected from least a in lipid acid, fatty acid amide or the silicone.
Described oxidation inhibitor is to be selected from β-(3; The 5-di-tert-butyl-hydroxy phenyl) the positive octadecanol ester of propionic acid, four [methyl-β-(3; The 5-di-tert-butyl-hydroxy phenyl) propionic ester] pentaerythritol ester, three [2.4-di-tert-butyl-phenyl] phosphorous acid ester or N; At least a in N '-two-(3-(3, the 5-di-tert-butyl-hydroxy phenyl) propionyl) hexanediamine.Compared with prior art, the invention has the advantages that with styrene-butadiene copolymer to substitute caking agent and polarity compatible agent, when guaranteeing necessary adhesive effect and tensile strength, improved transparency greatly.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail.
Hydrogenated styrene-butadiene-styrene block copolymers (SEBS) is to be selected from SEBS YH502 or SEBS YH561 (more than be the Ba Ling of China Petrochemical Industry petrochemical industry trade names).
Styrene-butadiene-styrene block copolymer (SBS) is to be selected from LG501N, YH791 or YH188 (more than be Korea S's LG/ high mountain trade names).
Styrene-butadiene copolymer specifically has KR-01, KR-03, KR-05 (more than be Korea S Philips trade names), 810,815 (more than be Japanese Asahi Chemical Industry trade names).
Mineral oil is that flash-point is higher than 200 ℃ naphthenic oil, concrete KN4010 naphthenic oil like the Kelamayi refinery.
Oxidation inhibitor is to be selected from antioxidant 1076 (β-(3; The 5-di-tert-butyl-hydroxy phenyl) antioxidant 1010 (four [methyl-β-(the 3 positive octadecanol ester of propionic acid); The 5-di-tert-butyl-hydroxy phenyl) propionic ester] pentaerythritol ester), oxidation inhibitor 168 (three [2.4-di-tert-butyl-phenyl] phosphorous acid ester), oxidation inhibitor 1098 (N; N '-two-(3-(3, the 5-di-tert-butyl-hydroxy phenyl) propionyl) hexanediamine).
Processing aid is to be selected from a kind of in lipid acid, amine hydroxybenzene, the silicone.Concrete like stearic acid, LYSI-100 silicone plastics additive.
Following table is the concrete proportioning raw materials of several embodiments of the present invention; And increased by one group of prescription that adds mineral filler and one group of conventional formulation as comparative example: wherein comparative example 8 adopts tradition to use the method for polarity compatible agent and caking agent, reaches bonding ABS effect.Wherein caking agent is selected thermoplastic polyurethane for use, is specially S70AW (German BASF trade names); The polarity compatible agent is to be selected from hydrogenation thermoplastic styrene butadiene rubber-maleic anhydride grafts SEBS-g-MAH, is specially 1901 (SEBS-g-MAH, U.S. Kraton company trade names).
Working method commonly used is:
Get feed composition by above-mentioned each proportioning respectively; With hydrogenated styrene-butadiene-styrene block copolymers (SEBS), styrene-butadiene-styrene block copolymer (SBS), even, blot oil back adding styrene-butadiene copolymer, thermoplastic polyurethane, polarity compatible agent, oxidation inhibitor, processing aid, mineral filler etc. and in mixer, mix with the mineral oil thorough mixing.Mixed material is sent in the twin screw extruder, sets the processing temperature of suitable twin screw extruder, starting material through the twin screw high speed shear, mixing, extrude, tie rod, cooling, granulation promptly get and of the present inventionly penetrate sticking thermoplastic elastomer with ABS.
The performance of the thermoplastic elastomer of the foregoing description is tested and tested transparency with following method: it is (150 ± 2) mm * (100 ± 2) mm * (2 ± 0.3) mm testing plate that each product is injection molded into specification; Totally 10; Prepare the A4 paper that a printing has No. 5 words; Testing plate is placed on the A4 paper; See the readability of font; If can distinguish word, expression material transparency reaches this progression.Progression with the quantitaes transparency of synergetic testing plate.
The result is as shown in the table:
Remarks: the test condition of melt flow rate (MFR) is: 190 ℃ of temperature, pressure 2.16kg.
Can find out from the performance test of last table; Relatively and the conventional thermoplastic elastomerics, under the prerequisite of not adding mineral filler, transparency of products improves greatly; And after adding mineral filler on the basis of the present invention, can not destroy this performance of thermoplastic elastomer based yet.
