Description

A kind of production method of petrochemical industry occasion corrosion resistant anti-explosion cable sheath material
Technical field
The present invention relates to the production technical field of the production technology of cable, particularly cable sheath material.
Background technology
The raw materials for production of existing cable sheath are mainly polyolefin, epoxy resin, silane coupler and fire retardant, technique It is：After raw material is well mixed, it is placed in single-screw extruder, extrudes continuous material, the material of extrusion is directly by leading Draw and fall into pond cooling, material cutting granulates after cooling, packed after overall drying.
The defect of existing production technology is：The efficiency of extrusion plastic is low, and complex procedures, cooling effect is not good, is easily caused Plastic product particle deformation.
The content of the invention
The present invention seeks to propose that a kind of corrosion resistant that can overcome above prior art defect, that suitable oiling workshop is shared is anti- The production method of quick-fried cable sheath material.
The technical scheme is that：Dried after raw material is well mixed, be subsequently placed in double-screw plastic extrusion machine and extrude Continuous material, successively by being extruded by as little as high five working regions of temperature, is then cooled down, then continuous material cutting is granulated Material.
The inventive method is simple, reasonable, and feature is after raw material is well mixed, to be extruded again after drying, and And, successively by being extruded by as little as high five working regions of temperature, then cool down.The bulk material being made of the inventive method Petrochemical industry occasion corrosion resistant anti-explosion cable sheath is made after hot melt has advantages below：
1st, petrochemical industry occasion, under the erosion of oil fog, can be used 30 years.
2nd, 150-160 DEG C of hot water and steam are resistant to, GB/ can be passed through by GB/T10125-2012 salt spray test First method in T9274-2012（Infusion method）Acid resistance and alkaline resistance test, comprehensive corrosion resistance grade reaches B grades.
3rd, fire resistance is strong, can pass through A as defined in IEC60332 grades of fire retardancy test.
4th, modulus of elasticity reaches 2800/3300MPa at 120 DEG C, all better than other any hybrid resin materials.
5th, antistatic effect is good, and explosion-proof performance is good, in use, will not be rubbed because of with ground or other objects Wipe, produce electrostatic.
Further, raw material of the present invention is by polyolefin, polyether sulfone, aqueous polyurethane, epoxy resin, silane coupled Agent, toughener, antistatic additive, fire retardant and anti-wear agent composition.Petrochemical industry application requirements cable has the explosion-proof performance of corrosion resistant, Therefore corresponding performance must also be possessed by being directly wrapped in the sheath material of cable outer layer.
Accessible special excellent results：The addition of polyether sulfone and aqueous polyurethane, can make cable jacket material have one Fixed antiseptic property, while the toughener and anti-wear agent that add, more improve the toughness and anti-wear performance of sheath material, make electricity Cable reduces abrasion in dragging or work progress；The addition of antistatic additive so that sheath material will not in cable moving process Friction with other objects causes electrostatic, increases explosion-proof performance, while also having certain anti-electromagnetic interference performance；Fire retardant Add so that cable sheath material has certain flame retardant effect.
It is the polyolefin, polyether sulfone, aqueous polyurethane, epoxy resin, silane coupler, toughener, antistatic additive, fire-retardant Agent and anti-wear agent account for raw material and always feed intake 30~38%, 28~34%, 10~16%, 12~15%, 0.1~0.3%, the 0.2 of quality respectively ~0.5%, 0.4~0.8%, 1.0~2.0%, 1.2~1.6%.The design starting point of the proportioning of above raw material：Consider petrochemical industry The property of all-in-one cable, cable and cable sheath material must have certain property, such as corrosion resistant performance, explosion-proof Performance, fire resistance, interference free performance etc., therefore, either petrochemical industry all-in-one cable, or its cable sheath material Material, it is necessary to reach these performances.But found during research sheath material proportioning, corrosion resistant performance requires the anti-of material Corrosive power is strong, and explosion-proof performance requires that material has certain electric conductivity, but if material has certain electric conductivity Can, then the interference free performance of material will cannot be guaranteed, while the inherent electric current of material will cause its aging to accelerate, it is anticorrosive Performance is reduced, therefore, and the use characteristic of the sheath material of statolith oiling workshop all-in-one cable adds antistatic additive, wear-resisting Agent and aqueous polyurethane, it is ensured that while material explosion-proof performance, also increase the abrasion-proof corrosion-proof performance of material.
Accessible special excellent results：Make sheath material have excellent corrosion resistant performance, explosion-proof performance, fire resistance, Interference free performance, service life is long.
As little as high five working regions of the temperature are respectively 170~180 DEG C, 180~200 DEG C, 200~220 DEG C, 220 ~240 DEG C and 240~260 DEG C.Each temperature range more than using can make to mix with the temperature in the single each heating work region of control Condensation material enters after twin-screw, can slowly heat, and homogeneous heating, after the fluxing point temperature for reaching material, various materials Material can be good at being merged, and produce a kind of new material.
The cooling is to use water cooling and air-cooled combination.In material processing, the cooling side being typically used for Formula is water cooling or air-cooled.The mode of water cooling, cooling velocity is general, and section needs to dry again after cooling；Air-cooled mode, it is cold But speed is slow, and in cooling procedure, the plastics of extrusion molding may be deformed upon.By the way of water cooling and air-cooled combination, no But it need not be dried after accelerating cooling velocity, and cooling, can directly cut dress bag, occur during will not also cooling down again Deformation, particle is uneven when causing to cut.
