Accompanying drawing explanation
Fig. 1 is the process step figure of a kind of thermoplastic elastomer raw material manufacture method for handle disclosed in the present invention.
Embodiment
The technique means realized for making the present invention, creation characteristic, reach object and effect is easy to understand, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiment one
Present embodiment discloses a kind of thermoplastic elastomer raw material, described thermoplastic elastomer raw material, for the manufacture of handle (such as golf club handle), adopts the soft exquisiteness of handle feel of described thermoplastic elastomer raw material, weathering resistance strong.
Its component comprises: hydrogenated styrene-butadiene block copolymer, softening oil, acrylic resin, Thermoplastic Vulcanizate, inorganic filler, antiwear assistant and weather-proof auxiliary agent, it is characterized in that, with above-mentioned each composition weight sum for radix, its each component proportion is:
Above-mentioned hydrogenated styrene-butadiene block copolymer (styrene-butadienetriblockcopolymer, be called for short: SBS) be white loose column solid, the relative molecular mass of chemical property: SEBS has a significant impact performance, relative molecular mass is large, solution viscosity is large, and bonding strength is high.Monomer ratio of components in product is very important, and along with the ratio S/B of vinylbenzene with divinyl increases, Polymer Solution Viscosity diminishes, and tensile strength and hardness increase.Have excellent tensile strength, elasticity and electrical property, tension set is little, and it is good to subdue with rebound resilience, and surface friction is large.Resistance to ozone, oxygen, uviolizing performance and styrene-butadiene rubber(SBR) similar.Ventilation property is excellent.The double bond contained due to main chain makes SEBS ageing-resistant poor, and under the oxidizing condition of high temperature air, butadiene block can be cross-linked, thus hardness and viscosity are increased.
Above-mentioned softening oil adopts rubber softening oil, and because the mooney viscosity of rubber is higher, bad construction time mixing, needs to be heated to 150 degree or higher temperature, waste energy very much, so need to add softening oil to reduce mooney viscosity; That commonly uses at present has the material such as carbon five and terpine resin, paraffin, mineral oil, polyisoprene.Above-mentioned different materials is very cheap, so mineral oil all used by general tire, sealed strip all uses paraffin, tackiness agent carbon five terpine resin etc.; And polyisoprene is liquid, above-mentioned substance can be substituted, but price is partially expensive.
Above-mentioned acrylic resin is a kind of crystalline polymer of compound with regular structure, is the thermoplastic resin of light oyster white pellet, tasteless, nontoxic, light weight.Relative density is 0.90 ~ 0.91, is one the lightest in resins for universal use.Satisfactory mechanical property, resistance toheat is good, its fusing point is about 170 DEG C, without under External Force Acting, 150 DEG C indeformable, and chemical stability is good, acid-and base-resisting and organic solvent, do not have an effect with most of pharmaceutical chemicals (as nitrosonitric acid, chromic acid solution, halogen, benzene, tetracol phenixin, chloroform etc.), and absorb water hardly.Polypropylene shortcoming is easily aging, and become fragile during low temperature, low temperature impact strength is poor, but can improve with adding the methods such as additive, blended or copolymerization.
Acrylic resin can be processed by injection moulding, extrusion molding, blowing, the method such as to reel off raw silk from cocoons.The various electrical component of suitable for making, televisor and radio receiver shell, anti-corrosion pipeline, sheet material, trolley part, Turnover Box, braided packing bag, packaging film Strapping Material, various container, various clothing articles, artificial lawn etc.
Above-mentioned Thermoplastic Vulcanizate (English is ThermoplasticVulcanizate), referred to as TPV, the Chinese of Thermoplastic Vulcanizate is referred to as thermoplastic elastomer (English ThermoplasticRubber), referred to as TPR, if the title of Thermoplastic Vulcanizate put off until some time later in detail a bit, that should be thermoplastic dynamic perduren (English is ThermoplasticDyamicVulcanizate), added " dynamically " 2 word be more specifically understand technique---the dynamic vulcanization producing this Thermoplastic Vulcanizate, this technique refers to make the vulcanization of rubber in rubber and thermoplastic molten Blending Processes, certainly also constantly mix mutually with thermoplastics while sulfuration at rubber, therefore the rubber cured be as dispersed phase distribution in thermoplastics external phase.
From the performance of Thermoplastic Vulcanizate, mainly there is application in the following aspects:
The first, SOFTTOUCH, soft feel (handle, handle).
The second, modifying plastics, improves toughness and the shock resistance degree of material.
Be different from general thermoplastic elastomer from the performance of Thermoplastic Vulcanizate, its application is more partial to mechanicals.
About above-mentioned inorganic filler, at present, inorganic filler is applied in plastics, rubber, coating, papermaking, not just in order to reduce costs, along with the improvement of its working method and the appearance of various coupling agent, give them with many-sided performance, weighting agent has been considered to the functional additive of a class.Inorganic filler is to granularity super-refinement, light specific gravity quantification, structural strength height strengthening development, adopt coupling agent table and process and hollow microsphere microballon skill art, for the industry products such as high weighting agent structural plastic goods, rubber item, coating, papermaking improve quality, reduce costs, create favourable condition.
Above-mentioned antiwear assistant is the important source material of rubber industry, though consumption is little, effect is very large, and polyester elastomer all be unable to do without antiwear assistant from being synthesized to processed and applied, and antiwear assistant significantly can promote the wear resisting property of thermoplastic elastomer raw material.
Plastics be a kind of easily affect by amblent air temperature factor be easy to aging material, plastic ageing is caused by solar radiation or hydrolytic action often, the interpolation of above-mentioned weather-proof auxiliary agent significantly can promote the conservation rate of the thermoplastic elastomer raw material for handle disclosed by the invention its colour-change and shock strength in drying, sun-drenched weather and in humidity, the insufficient weather of sunlight, effectively prevents the defect that material is easy to aging.
