Description
Technical field
The present invention relates to a kind of cable, particularly a kind of petrochemical equipment aging cable sheath rubber of resistance to hydrocarbons.The invention still further relates to the manufacture method of a kind of petrochemical equipment with the aging cable sheath rubber of resistance to hydrocarbons.
Background technology
A large amount of hydrocarbons is contained as oil, chemical solvents, inflammable gas etc. in petrochemical equipment district, in order to ensure on-the-spot electric operation safety, needs to adopt the cable that can bear hydrocarbons attack aged and operating safety for a long time.What prior art adopted is airtight lead-sheathing jacketed cable, and corrosion resistance is good, effectively can isolate hydrocarbons.But this type of cable has very large drawback, Heavy Weight, external diameter be large, be not easy to bend, and use occasion is limited, cable terminal end process complicated, lose time, and lead sheath contains a large amount of lead metals simultaneously, poisonous, large to environment, human health damage.
Summary of the invention
Primary and foremost purpose of the present invention is, overcome problems of the prior art, there is provided the resistance to hydrocarbons of a kind of petrochemical equipment aging cable sheath rubber, adopt the cable that this rubber is made, suitable with the resistance to hydrocarbons performance of existing lead sheathed cable, but external diameter is little, lightweight, bending radius is little, terminal process is simple, has environment friendly, on HUMAN HEALTH without impact.
For solving above technical problem, a kind of petrochemical equipment provided by the invention aging cable sheath rubber of resistance to hydrocarbons, feed composition and the weight content of described rubber are as follows, polyvinyl chloride (PVC) RESINS PVC-SG2 premium grads: 15 parts; Paracril NBR3305:5 part; Hexanodioic acid propanediol polyester: 3 ~ 7 parts; Epoxy soybean oil: 2 ~ 3 parts; Barium stearate: 0.6 ~ 1 part; Lead sulfate tribasic: 1 ~ 1.5 part; Diphenylol propane: 0.05 ~ 0.1 part; Antimonous oxide: 3 ~ 5 parts; Chlorinated paraffin-52: 0.1 ~ 0.5 part; Ferrocene: 0.3 ~ 0.5 part.
Relative to prior art, the present invention achieves following beneficial effect: (1) the mean polymerisation degree of polyvinyl chloride (PVC) RESINS is larger, the resistance toheat, tensile strength etc. of resin are more excellent, but embrittlement temperature can reduce, and affects resistance to low temperature, in order to reach the Good All-around Property of PVC plastic, the present invention adopts PVC-SG2 premium grads as base-material, its mean polymerisation degree is suitable for, and the few purity of the impurity contained is high, has oil resistant, fire-retardant, ageing-resistant, resistance to ozone, physical strength are high; The present invention adopt polyvinyl chloride (PVC) RESINS PVC-SG2 premium grads and paracril NBR3305 blended, to strengthen oil resistant and solvent resistance; Paracril is along with the increase of its acrylonitrile content, and oil-proofness, solvent resistance, physical strength, heat aging performance are increased; The acrylonitrile content of paracril NBR3305 is high, can reach 32% ~ 35%, has heat-proof aging, oil resistant, solvent resistance, and have do not move, non-volatile, not for oil and solvent-extracted characteristic, overall target is good; And paracril NBR3305 is suitable with PVC-SG2 molecular weight, and with reaching completely compatible, improve oil resistant and the solvent resistance of polyvinyl chloride, but cold tolerance is poor, needs to improve resistance to low temperature by cold resistant plasticizer.(2) hexanodioic acid propanediol polyester is as softening agent, and molecular weight is large, and volatility is low, and transport property is little, and oil resistant and resistance to suds are extracted out, good heat resistance.(3) epoxy soybean oil has the effect of softening agent and stablizer concurrently, have excellent heat-resisting, light fastness, consistency are good, volatility is low, be not easily drawn out of, and have good electrical insulation capability and good winter hardiness, nontoxic, the drawback that paracril NBR3305 causes compound resistance to low temperature difference can be improved, also heat-resisting, cold-resistant with can realize simultaneously with hexanodioic acid propanediol polyester, and improve complete processing.(4) polyvinyl chloride easily produces decomposition under long-term light or comparatively high temps effect in atmosphere, discharge hydrogenchloride, and hydrogenchloride itself is a kind of catalyzer promoting to decompose, and needs to add the decomposition that stablizer stops or delays PVC for this reason.Barium stearate of the present invention doublely can do stablizer and lubricant, nonstaining property, and tribasic lead sulfate has excellent thermotolerance and electrical insulation capability as stablizer, photostabilization is good, and water-absorbent is little, large to the absorbing power of hydrogenchloride, opacifying property is good, and resistance to weathering is good; Share with barium stearate and can improve electrical insulation capability and ageing-resistant performance.(5) anti-aging agent of the prior art is best with the long-term anti-aging effect of diphenylol propane to PVC; it is colorless crystalline powder; water insoluble; have the effect of stablizer, oxidation inhibitor and softening agent concurrently; the oxicracking preventing polyvinyl chloride can be played; protection softening agent, from oxidation, makes mixing materials have protecting against shock.(6) antimonous oxide and chlorinated paraffin-52 are as fire retardant, and the two is with beaming back coating effect, strengthen flame retardant properties; Antimonous oxide is white, nontoxic, odorless powder, itself and clorafin burns time generate antimony chloride and rise coating effect and dilution effect, make material and air exclusion, reach flame retardant effect, but the amount of being fuming is large during antimonous oxide burning, and its sour gas produced has corrodibility, need to add smoke elimination acid inhibitor for this reason.Clorafin is cheap simultaneously, and there is the effect of lubricant, mixing materials is made to be easy to processing, improve processing speed, when preventing plastic working and the adhesion on equipment or other surfaces, good in roller and release property to make to have in the mixing materials course of processing, ensure the surface smoothness of goods, kinetic viscosity during internal friction and the melting of plastics can be reduced simultaneously, prevent because strong internal friction causes goods overheated.(7) ferrocene is as smoke elimination acid inhibitor, and be orange powder, chemical stability is good, heatproof is high, can reach 400 DEG C, and it can be converted into rapidly α-Fe2O3 when mixing materials combustion decomposition goes out hydrogenchloride, make generation CO and CO2 to having carbonized catalysis calcination, thus reduce the generation of jet-black.
