Description
Technical field
The present invention relates to a kind of interpolation superconduction sooty high-tension cable material and production method thereof.
Background technology
In materials such as plastic, rubber, add very a spot of superconduction carbon black and just can change the antistatic or conduction property of macromolecular material, and mechanical properties such as its hardness, tensile strength, elongation are improved.Show that the superconduction carbon black improves the aspect of performance of the selectivity coupling of cable-flame retardant and electroconductibility, seems particularly important to ensureing the colliery with the quality and the security of high-tension cable.It is reported, nearly 3000 mouthfuls of the explored coal mine of China, nearly half develop and operate, the colliery with cable (electric drill cable, umbilical cable, signal cable etc.) demand and potential market very big.China is used for transmitting and distributes the cable of electric energy to be divided into low pressure, pressure, high-tension cable and extra-high-tension cable, extra-high-tension cable by the voltage classification at present.And the high-tension cable of comparative maturity is also counted VXC-68#, the VX-500# of U.S. Cabot company with the superconduction carbon black products; The 420B of Germany Degussa company, Printex XE-2B; The 600JD type of the 3350B type superconduction carbon black of MIT and Dutch AKZO company.These product prices are higher, and it is untimely to supply, and does not satisfy the demand of domestic market.And being used for the development of high pressure, extra-high-tension cable, China's superconduction carbon black also is in the starting stage.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provides that a kind of production technique is simple, the interpolation superconduction sooty cable material and the method for making thereof of high comprehensive performance.
The present invention adds superconduction sooty cable material, and each component and prescription by weight percentage thereof are: superconduction carbon black 3～9%, chlorinated polyvinyl chloride CPVC 70～85%, softening agent 7～13%, 2～5% parts of stablizers, lubricant 0.5～3%, anti-low temperature modification agent 2～2.5%; Each composition weight sum is 100%.
Wherein: stablizer adopts humic acids zinc salt or lead salt, and softening agent adopts phthalic acid two sufferings, and lubricant is a polyethylene wax, and anti-low temperature modification agent is a propylene glycol.
Used superconduction sooty technical parameter: particle diameter 5～18nm, specific surface area 600～1500mg/g, resistance value 0.03～0.1k Ω cm, DBP absorption value 150～250ml/100mg, weight loss on heating≤1.0%; Measure demonstration by the SEM scanning electron microscope: surfaceness is suitable, good uniformity.
The method for making that the present invention adds superconduction sooty cable material is:
(1) the superconduction carbon black proportionally is added in the chlorinated polyvinyl chloride powder, adds softening agent, stablizer, lubricant, anti-low temperature modification agent etc. more respectively, put into high-speed mixer to mix; And under 90～130 ℃ of temperature, mediate 20～50min;
(2) under 110～150 ℃ of temperature, in the mixing 15～35min of dual-screw-stem machine, extruding pelletization is cooled to 20～40 ℃ of room temperatures then, and is standby; The general 2mm χ 3mm cylindrical particle that is a granulated into;
(3) go up the extruding machine direct production and go out high pressure, extra-high-tension cable.
The present invention adds superconduction sooty cable material, meets DL 401-91 People's Republic of China (PRC) industry standard high-tension cable selection standard, and is similar to the VX-500# of U.S. Cabot company, is particularly suitable for colliery high pressure, extra-high-tension cable material.Production technique of the present invention is simple, the product high comprehensive performance, and quality index such as voltage rating, cable sheath Insulation Material all meet the requirements.
Embodiment
Further specify the present invention with embodiment below, but the present invention is not limited.
According to 5% of gross weight the superconduction carbon black is added among the CPVC that accounts for gross weight 80%, add dioctyl phthalate (DOP), add stablizer humic acids lead salt, add lubricant polyethylene wax, add anti-low temperature modification agent propylene glycol by gross weight 10% respectively by gross weight 2.5% by gross weight 0.5% by gross weight 2%, after preparing in proportion, put into high-speed mixer, under 90 ℃ temperature, mediate 30min; Under 120 ℃ of temperature,, extrude and cause 2mm χ 3mm cylindrical particle in the mixing 35min of dual-screw-stem machine, produce high pressure, extra-high-tension cable material after the cooling, the product performance test result shows, produces cable material performance: hardness 100+/-5 Shao Shi D, 1sec by the inventive method; Density 1.58Kg/m
3Tensile strength 65MPa; Specific heat 1.45kJ/kg.k; Low-temperature impact embrittlement rate (20 ℃)+20/-10; Sizing material resistance 110 * 10
6Volume specific resistance Ω .m.And the performance of common CP VC sheath material: hardness 95+/-5 Shao Shi D, 1sec; Density 1.52Kg/m
3Tensile strength 60MPa; Specific heat 1.47kJ/kg.k; Low-temperature impact embrittlement rate (20 ℃)+19/-11; Sizing material resistance 110 * 10
13Volume specific resistance Ω .m.
Find out by top, (usage quantity is 1/5 of an ordinary carbon black amount to add the superconduction carbon black according to 5% of gross weight, general conduction 1/3) be used for the manufacturing of CPVC high-tension cable, do not reduce CPVC sheath material material properties such as " tensile strengths ", and volume specific resistance is more much smaller than common CP VC sheath material, both had antistatic property, the bigger breakdown performance of anti-the electric current had been arranged again.If superconduction sooty addition is reduced, the breakdown performance of anti-the electric current also can improve.Otherwise as adopting ordinary carbon black and general graphitized carbon black, because addition is more, the high-tension cable that produces is all good not as interpolation superconduction sooty from the aspects such as antistatic and electroconductibility of the strength of materials and sizing material resistance.
