Abstract
The invention relates to a printable thermoplastic elastomer composition. The components of the composition according to weight percentages of the raw materials are as follows: 20%-30% of a block styrene copolymer, 30%-45% of filling oil, 10%-15% of maleic anhydride-grafted block styrene copolymer, 10%-20% of polarity polypropylene, 5%-10% of a filler, 2%-5% of a wear-resisting agent, 1%-2% of a stabilizing agent and 1%-3% of a processing auxiliary agent. The composition is obtained by mixing the above materials according to a certain ration in a high-speed mixing machine, and performing a melt blending extrusion in a twin-screw granulating machine under a processing temperature of 190-230 DEG C. The thermoplastic elastomer composition can be printed with common ink, has excellent printing fastness, comfortable feel and good wear resistance, and can be widely applied to the field of tool handles, toothbrush handles, wire cables, automobile parts, etc.
Description
Technical field
The present invention relates to polymeric material field, particularly a kind of thermoplastic elastomer that can print is mainly used in handle for tool, toothbrush handle, electric wire, the related productss such as auto parts machinery.
Background technology
Thermoplastic elastomer has the physical and mechanical properties of vulcanized rubber and the performance of technical process of nonrigid plastic, is a kind of novel high polymer material between rubber and resin, not only can replace part rubber, can also make plastics obtain modification.Owing to not needing as rubber, to pass through again hot sulfurization, thereby use simple plastic processing machinery can make at an easy rate the finished product, make the rubber industry Production Flow Chart shorten 1/4, energy efficient 25%～40%, raise the efficiency 10～20 times, can be rated as again material and Technology revolution of rubber industry.The rubber that the thermoplastic elastomer thermoplastic elastomer has and the dual property of plastics and broad characteristic are widely used in electric wire, building, and auto parts machinery, household electrical appliances, medicine equipment, instrument, stationery is on the products such as daily necessities.
A kind of thermoplastic elastomer that styrene series thermoplastic elastomer is the most similar to rubber performance.Mainly contain at present 4 types, that is: styrene-butadiene-styrene block copolymer (SBS); Styrene isoprene styrene block copolymer (SIS) (SIS); Styrene-ethylene-butylene-styrene block copolymer (SEBS); Styrene-ethylene-propylene-styrene type segmented copolymer (SEPS).SEBS and SEPS are respectively the hydrogenation multipolymers of SBS and SIS.Styrene series thermoplastic elastomer is compared other thermoplastic elastomer, and cost performance is higher, is that world wide production is maximum at present, an analog thermoplastic elastomer of consumption maximum.Because styrenic thermoplastic elastomer's surface tension is little, polarity is little, and common ink is difficult to printing and gets on, and effect is bad, and is high with special printing ink price, increased product cost.In order to solve problems, the present invention proposes a kind of can be with the thermoplastic elastomer of common ink printing, and hand feel and drape, wear resistance is good.
Summary of the invention
The invention provides a kind of thermoplastic elastomer that can print, and hand feel and drape, wear-resisting good.Its raw material weight per-cent is:
Described block styrene multipolymer is styrene-ethylene-butylene-styrene block copolymer (SEBS), styrene-ethylene-propylene-styrene type segmented copolymer (SEPS) at least a.Specifically rise the G1651 of company (KRATON) such as U.S. section, G1654, G1633,4055 of Japanese Kuraray, 4044,6151,6154,6159 of Taiwan rubber limited-liability company, 2315,2314 of Italy ENI company, the CH-6170 of Spain Dynasol.
Described extending oil is saturated straight-chain paraffin oil, naphthenic oil at least a, and such as 150 of U.S. sun-stone company (SUNPAR), the 150SN of the two imperial companies of Korea S, the KN4020 of Karamay, Xinjiang refinery etc.
Described maleic anhydride graft block styrene multipolymer is maleic anhydride graft SEBS, specifically rises the G1901 of company such as U.S. section, G1924,7131 of Taiwan rubber limited-liability company.
Described polar polypropylene is maleic anhydride inoculated polypropylene, acrylic acid-grafted polypropylene at least a, and specifically such as the PO1020 of Exxon Mobil, the JPM-2 of the green safe plastic cement of Xinchang company limited, 9801 etc. of the liter of Shanghai day.
Described filler is at least a in talcum powder, calcium carbonate, mica powder, kaolin, the barium sulfate.The order number requires more than 2500 orders, and degree of activation is more than 95%, if the order number is lower than 2500 orders, degree of activation is lower than 95%, easily scratch, and printing ink is easily wiped off, and the printing fastness can be affected.
Described anti-wear agent is the silicone powder, silicone master batch, at least a in the fluoropolymer.Specifically such as the MB50-001 of Dow corning company (DowCorning), the MG4502 of the green safe plastic cement of Xinchang company limited etc.
Described stablizer is benzophenone, phosphorous acid esters, Hinered phenols, hindered amines or the mixture that forms by a certain percentage.Specifically such as the Irganox 1010 of Ciba, Irganox 168, Irganox1076, UV531, UV327 etc.
Described processing aid is at least a among stearic acid, Zinic stearas, calcium stearate, the TAF.
Add man-hour, above-mentioned raw materials is taken by weighing by a certain percentage, at high-speed mixer and mixing 30min, it is mixed.After mixing, processing temperature is extruded and is obtained through melt blending in dual-screw pelletizer under 190 ℃ of-230 ℃ of conditions.
It is base-material that the present invention adopts the block styrene multipolymer, and the adjustment by prescription and complete processing has solved the difficult problem that styrene series thermoplastic elastomer is not easy to print, and hand feel and drape, and wear resistance is good, has increased handiness and the added value of product design.
Printing ink scratch resistance evaluation method A
Raw material made the grain after, 80 ℃ of lower bakings one hour in baking oven, get sheet material with injection moulding machine, stamp pattern at sheet material with the mode of bat printing again, evenly adhere on the sample until use 3M board 610 behind the ink setting or 810 adhesive tapes, and make it to cement for one time in adhesive tape back side pressure with finger, then catch the two ends of adhesive tape with moderate speed's pull-up with hand, if printing ink is arranged on the adhesive tape, illustrate that the printing ink firmness is inadequate.
