Abstract
The invention discloses an oil-proof PVC sheath material for earphone wire, which is obtained by evenly mixing and then, in a double screw extruder, extrusion-granulating the following raw materials, based on weight part, of: 45-50 parts of WS-1300, 25-35 parts of W-2050, 20-25 parts of mixed filler, 2-5 parts of YC-300 and 0.5-2.0 parts of LOCK, the mixed filler is formulated by HD-2500 and CCR-603 in accordance with weight ratio of 1:1-2; the sheath material is not liable to be extracted by organic solvent like oil product after being processed to the earphone wire, has preferable corrosive resistance to organic solvent like oil product, and still has good elasticity and softness after being immersed in organic solvent like oil product. Therefore, the invention is oil-proof PVC sheath material for earphone wire that has preferable oil product resistance and softness stability.
Description
Technical field
The present invention relates to the cable jacket material, be specifically related to oil-proof PVC sheath material for earphone wire.
Background technology
The outermost sheath material of cable is important protective layer, has anti-Japanese solarization, and radioprotective is wear-resisting, heat-resisting, ageing-resistant, performances such as resistance to chemical attack; As publication number is CN101407612A, open day is on April 15th, 2009, the patent application name is called the soft thermoplastic sheath material that is used for mobile electric power and umbilical cable, discloses the composition of raw materials of being made up of chlorinatedpolyethylene, silane coupling agent, polyethylene wax softening agent, anti-aging agent, stablizer, fire retardant and strengthening agent and makes through the screw extrusion press extruding pelletization.The composition of raw materials commonly used of producing the PVC sheath material of earphone cord at present comprises: polyvinyl chloride resin, softening agent, weighting agent and stablizer etc.As prescription be: the earphone cord PVC sheath material that SH-200 (polyvinyl chloride resin) 45-50 part, about 35 parts of TOTM (triisooctyl trimellitate softening agent), HD2500 (water-ground limestone weighting agent) 20-25 part, the material component of field (stablizer) 2-3 part of being full of make, though the earphone cord made from this PVC sheath material has better softness characteristics, but the relatively poor and soft less stable of oil resistant product corrosion, easily by oil corrosion, cause earphone cord to attenuate, hardness increases, and having lost earphone cord should have softness characteristics.
Summary of the invention
Technical problem to be solved by this invention provides a kind of oil-proof PVC sheath material for earphone wire with oil resistant product corrosion preferably and soft stability.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: oil-proof PVC sheath material for earphone wire, the composition of raw materials that comprises following weight parts is through uniform mixing, make behind the twin screw extruder extruding pelletization: 45～50 parts of WS-1300,25～35 parts of W-2050,20～25 parts of mixed fillers, 2～5 parts of YC-300,0.5～2.0 part of LOCK, described mixed filler is formulated by weight 1: 1～2 by HD-2500 and CCR-603.
Also comprise the UV-201 (UV light absorber) of 0.1～0.5 weight part in the above-mentioned raw materials prescription, be commercially available UV light absorber, can make the earphone cord after the processing have the absorption action of ultraviolet ray.
WS-1300 in the above-mentioned prescription (polyvinyl chloride) is commercially available polyvinyl chloride resin powder; W-2050 (hexanodioic acid kind polyester) is commercially available softening agent; HD2500 (water-ground limestone) and CCR-603 (super-fine active calcium carbide) are commercially available weighting agent; YC-300 (thermo-stabilizer) is commercially available thermo-stabilizer; LOCK (titanium dioxide) is commercially available toner.
Compared with prior art, the invention has the advantages that oil-proof PVC sheath material for earphone wire, the raw material that mixed filler, YC-300 thermo-stabilizer and the titanium dioxide of being made up of WS-1300PVC resin-oatmeal, W-2050 softening agent, HD2500 and CCR-603 formed makes; WS-1300 has 1300 the polymerization degree, and with the raw material of WS-1300 as the earphone cord sheath material, processing temperature need not surpass 150 ℃ when the processing earphone cord, and the external diameter of processing earphone cord is easy to control, and the earphone cord outward appearance that processing obtains is light and smooth; HD2500 is that granularity can reach 2500 order calcium carbonate superfine powders, the effect of filling and increasing the insulation resistance of product is mainly played in use in this prescription, also because of its fineness height, make the PVC sheath material that obtains be processed into earphone cord easily, CCR-603 has superfine active, good fluidity, work in-process can be filled up the cavity of sheath material, and crosslinked with the polyvinyl chloride resin plasticizing, make the sheath material space that makes few, oil product and other organic solvent are difficult for the lime carbonate of filling is separated out; CCR-603 mixes use with HD2500, the PVC sheath material that makes like this is processed into earphone cord easily, and processing obtains earphone cord and has oil resistant product and other organic solvent corrosive advantage; W-2050 and WS-1300 have good consistency, the fusion time of WS-1300 is done sth. in advance, can also attract and fixedly HD-2500 and CCR-603 etc. not to the effect of the surface transport of PVC goods, so be processed into this sheath material and more difficultly behind the earphone cord taken out by organic solvent extractings such as oil products, corrosive property with organic solvent such as better oil resistant product still has better elasticity and softness characteristics after soaked by organic solvent such as oil product.Therefore the present invention is the oil-proof PVC sheath material for earphone wire with oil resistant product corrosion preferably and soft stability.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail.
Embodiment
Oil-proof PVC sheath material for earphone wire, by 48 parts of WS-1300,25 parts of W-2050,22 parts of mixed filler, 3 parts of YC-300,1.5 parts of LOCK, 0.3 part of UV-201 that are made up of at 1: 1 by weight HD2500 and CCR-603 is raw material, through uniform mixing, behind the twin screw extruder extruding pelletization, make the PVC sheath material.
