The cable sheath material disclosed by the invention has very good resistance to oil and corrosion, and has good characteristics of wear resistance, heat resistance, electrical insulativity, mechanical property and the like, and meets the use requirements of special working environments such as an oil platform and a fuel oil pool, and the service life of a cable is effectively prolonged.
Description
Technical field
The present invention relates to a kind of oil-resistant polyvinyl chloride cable jacket material and preparation method thereof, belong to cable material field.
Background technology
PVC cable material is resin based on polyvinyl chloride, adds the additive such as stablizer, softening agent, mineral filler, auxiliary agent and lubricant, mediates extrude and the particle prepared through mixture.As traditional cable material, it has excellent fire-retardant, electrical isolation, wear-resistant, good mechanical property and the advantage such as wide material sources, low price, and market share the most important market share at home.At present along with the continuous expansion of the electric wire market requirement and deepening continuously of China PVC scientific research and development work, more and more strict to the performance requriements of polyvinyl chloride cable material.On existing market, polyvinyl chloride cable material also exists the shortcoming of oil resistance difference, and under oily medium, performance degradation phenomenon easily appears in long term operation, cannot meet the need of market.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of oil-resistant polyvinyl chloride cable jacket material and preparation method thereof is provided.
For achieving the above object, the technical solution used in the present invention is as follows: a kind of oil-resistant polyvinyl chloride cable jacket material, be made up of the raw material of following weight part: SG-3 type polyvinyl chloride 74-96, poly(4-methyl-1-pentene) 49-67, ethylene-vinyl alcohol copolymer 26-44, calcium-zinc composite stabilizing agent 2-3, wollastonite powder 18-24, dimethoxyethyl phthalate 16-22, fluorinated silicone oil 5-10, montanic acid calcium 3-5, TriMethylolPropane(TMP) 4-6, tetrahydrofurfuryl amine 2-4, glycerine triacetyl hydroxy stearic acid ester 4-6, tuff micro mist 15-20, precipitated silica 18-24, epoxidized methyl acetorieinoleate 10-15, distearyl acid glycol ether diester 10-15, fire retardant 15-20, N, N'-pair-(3-(3, 5-di-tert-butyl-hydroxy phenyl) propionyl) hexanediamine 1-2,
The preparation method of described fire retardant is as follows: the ratio of a, in mass ratio 4-8:3-6:2-3 takes boehmite, brucite, polynite mix, pulverize, cross 150-200 mesh sieve, then the slurries that concentration is 50-60% are made in adding water making beating, then add the Na of NaOH and 15-25% of ZnO, 20-30% of slurry weight 4-6%
2sn(OH)
6, heating in water bath is to 70-80 DEG C, and stirring reaction 6-8h, is cooled to room temperature, and suction filtration, washing, drying are placed on 550-650 DEG C of temperature lower calcination 2-4h, are cooled to room temperature, and then add the NaMoO of weight of material 3-6%
4, 3-6% Ca (NO
3)
2with the LiNO of 30-50%
3, and add appropriate dehydrated alcohol grinding 1-2h, make it fully mix, 70-80 DEG C of dry 4-6h, then calcine 3-5h at being placed in 250-300 DEG C, be cooled to room temperature, pulverize, cross 200-300 mesh sieve; Tricresyl phosphate (butoxyethyl group) ester of 5-10%, 5-10% dimethyl methyl phosphonate, the dicyclopentadiene of 3-6% and the dimethyl diphenyl polysiloxane of 2-4% is added in the material that b, step a obtain, 500-1000rpm stirs 10-15min, dry, pulverize, cross 200-300 mesh sieve.
A preparation method for oil-resistant polyvinyl chloride cable jacket material, comprises the following steps:
(1) by SG-3 type polyvinyl chloride, poly(4-methyl-1-pentene), ethylene-vinyl alcohol copolymer and dimethoxyethyl phthalate add in kneader, when stirring makes material temperature rise to 70-80 DEG C, add wollastonite powder, tuff micro mist, precipitated silica, epoxidized methyl acetorieinoleate, distearyl acid glycol ether diester, when stirring makes material temperature rise to 85-95 DEG C, add montanic acid calcium, TriMethylolPropane(TMP), glycerine triacetyl hydroxy stearic acid ester, fire retardant, stirring makes material temperature rise to 100-110 DEG C, material is gone in cold mixer, add remaining raw material, stirring makes material temperature be down to 45-55 DEG C, discharging,
(2) the above-mentioned material mixed is dropped into twin screw extruder and carry out extruding pelletization, twin screw extruder processing temperature is 150-170 DEG C, and rotating speed is 30-50r/min, namely obtains sheath material of the present invention after pellet drying, screening, packaging.
