Abstract
The invention discloses a matte thermoplastic elastomer which comprises, by weight, 20%-45% of styrene block copolymers, 30%-60% of filling oil, 5%-20% of polypropylene, 5%-12% of olefin thermoplastic elastomers, 0.5%-4% of organic matting agents, 0.1%-2% of stabilizers, 0.01%-0.05% of cross-linking agents and 0%-30% of inorganic filler. A preparation method includes: proportionally weighing raw materials, mixing the styrene block copolymers, the inorganic filler, the polypropylene, the olefin thermoplastic elastomers, the organic matting agents, antioxidants, the cross-linking agents and other auxiliaries in a high-speed mixer, and placing the mixture into a double-screw extruder for melt extrusion and extruding out prior to cooling, drying and grain cutting so that a finished product is obtained. By the method, the cross-linking agents of a proper amount and the organic matting agents of a proper amount are added into the thermoplastic elastomer, so that the prepared thermoplastic elastomer has a matting characteristic, and a visual effect is extremely soft. Intrinsic physical performances of the thermoplastic elastomer are basically kept, and the matte thermoplastic elastomer is extraordinarily excellent in processability, suitably applied to interior decoration materials of household appliances, automobiles and the like and particularly suitable for large-area injection molding products.
Description
Technical field
The present invention relates to composition for thermoplastic elastomer of a kind of sub-smooth type and preparation method thereof, belong to polymer modification and processing technique field.
Background technology
Thermoplastic elastomer is called for short TPE/TPR, claims again synthetic chloroprene rubber or synthetic rubber.Have the snappiness of traditional cross-linking vulcanized rubber, the excellent properties such as ageing-resistant under its product normal temperature, again plasticization moulding under the high temperature, possess common plastics processing side more, the wide characteristics of processing mode.Can adopt injection moulding, extrude, the processing mode production such as blowing, 100% direct secondary use after pulverize corner, the mouth of a river, and add and do not have niff man-hour is a kind of type material of environmental protection.Both simplified the course of processing, and cut down finished cost again, so thermoplastic elastomer TPE/TPR material become the Latest Materials that replaces traditional rubber, its environmental protection, nontoxic, hand feel and drape, exquisite appearance make product have more intention.The fields such as widespread use and auto parts machinery, sealed strip, electric wire, medicine equipment.Wherein styrene block copolymer uses the most extensive because excellent performance and cost are low.
With the thermoplastic elastomer of styrene block copolymer blending and modifying gained, surface gloss is higher usually, presents the light type now, and a lot of occasions need the very low thermoplastic elastomer of glossiness, such as auto parts machinery, electric wire is given a kind of comfortable visual impression of people.Existing technology generally is to obtain by the silicon-dioxide that adds delustring or the elastomerics that adds dynamic vulcanization, material flowability descends much as a result, and matt effect is not fine, do not have a kind of soft visual impression, be not suitable for the large goods of shaping area, such as automatic foot-mat.
Problem to be solved by this invention is exactly matt effect and the very soft styrene block thermoplastic elastomer of visual effect that obtains a kind of excellence, the physicals excellence of resulting materials and processing fluidity are very good again, are fit to very much the big area goods such as automatic foot-mat.
Summary of the invention
The invention provides a kind of matt effect and the very soft styrene block thermoplastic elastomer of visual effect of excellence, the physicals excellence of resulting materials and processing fluidity are very good again, are fit to very much the big area goods such as automatic foot-mat.
The present invention is achieved through the following technical solutions: a kind of composition for thermoplastic elastomer of matt effect of excellence, and meter comprises: styrene block copolymer 20%～45% by weight; Extending oil 30%-60%, polypropylene 5%-20%; Olefin hydrocarbons thermoplasticity elastic body 5%-12%; Organic matting agent 0.5%～4%; Stablizer 0.1%～2%; Linking agent 0.01%-0.05%, mineral filler 0%-30%.
Described block styrene multipolymer is styrene-ethylene-butylene-styrene block copolymer (SEBS), vinylbenzene
-ethylene-propylene-styrene type segmented copolymer (SEPS) at least a.Specifically rise company (KRATON) such as U.S. section
G1651, G1654, G1633,4055,4044 of Japanese Kuraray, 6151 of Taiwan rubber limited-liability company,
6154,6159,2315,2314 of Italian 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 polypropylene is homopolymerization or Co-polypropylene, and polypropylene can cause degraded under the effect of superoxide in the course of processing, improves flowability, and (230 ℃, 2.16kg) requiring is 1-10 therefore to melt finger.If polyacrylic melting refers to be lower than 1, processing fluidity descends, and decorative pattern easily appears in product surface, is not suitable for the production of big area goods, if polyacrylic melting refers to be higher than 10, and melt mobile excessive, melt strength is bad, the bad control of Shooting Technique.Concrete T30S such as grand celebration.
Described olefin hydrocarbons thermoplasticity elastic body is POE, and is concrete such as 8140 of Dow Chemical company.POE can cause partial cross-linkedly under the effect of superoxide in process engineering, improves the matt effect of material, does not reduce the snappiness of material, and visual effect is soft especially.
Described organic matting agent is crosslinked organosilicon microballoon resin, concrete KMP-590 such as Japanese SHIN-ETSU HANTOTAI.The microballoon organic matting agent can increase the matt effect of material, and can increase flowability, improves Drawing abillity.
Described stablizer is benzophenone, phosphorous acid esters, Hinered phenols, hindered amines or form by a certain percentage mixed
Compound.Specifically such as the Irganox 1010 of Ciba, Irganox 168, Irganox1076, UV531, UV327 etc.
Described linking agent is dicumyl peroxide (DCP), and specifically such as the BC-FF in Aksu, addition is at 0.01-0.05.If the addition of DCP is lower than 0.01, matt effect is bad, if the addition of DCP is higher than 0.05, and the composition property decline of flowing, decorative pattern can appear in product surface, is not suitable for producing the large goods of area.
Described filler is at least a in talcum powder, calcium carbonate, mica powder, kaolin, the white carbon black.
