Abstract
The invention relates to an insulation rubber for cables, which is prepared by the following materials measured in mass percentage: 39.14 percent of EPDM (Ethylene-Propylene-Diene Monomer), 3.52 percent of zinc oxide, 0.97 percent of antiager RD, 1.96 percent of paraffin, 0.39 percent of stearic acid, 0.78 percent of silane coupling agent A-172, 15.66 percent of superfine French chalk, 11.74 percent of calcium powder, 15.66 percent of calcinated argil, 3.52 percent of white carbon black, 2.94 percent of paraffin oil, 1.76 percent of vulcanizing-agent dicumyl peroxide, and 1.96 percent of crosslink agent TAIC (triallyl isocyanurate). The insulation rubber for cable has low manufacturing cost, the tensile intensity before aging is 8.5 N/mm 2, and the elongation at break before aging is 350 percent.
Description
Technical field:
The present invention relates to a kind of cable insulation rubber.
Background technology:
Along with development of technology, cable is applied to the various fields of all trades and professions with insulation rubber, and demand is increasing, ethylene-propylene rubber(EPR) is because of its numerous advantages, become widely used a kind of insulating material in the electric wire industry, but higher because of its production cost, production and use have been subjected to certain restriction.
Summary of the invention:
In order to overcome disadvantages of background technology, the invention provides a kind of cable insulation rubber, this cable is low with the insulation rubber production cost, and aging preceding tensile strength is 8.5N/mm
2, aging preceding elongation at break is 350%.
Technical scheme of the present invention is: this insulation rubber is made by following raw materials according, and each raw material is calculated by mass percentage: terpolymer EP rubber 39.14%, zinc oxide 3.52%, anti-aging agent RD 0.97%, paraffin wax 1.96%, stearic acid 0.39%, silane coupling A-1720.78%, superfine talcum powder 15.66%, calcium powder 11.74%, calcinated argil 15.66%, white carbon black 3.52%, Valelinum Liquidum 2.94%, vulcanizing agent dicumyl peroxide 1.76%, linking agent TAIC1.96%.
Terpolymer EP rubber 2070 is provided by Jilin Petrochemical company in the such scheme, and it has superior heat-resisting, resistance to oxidation, anti-ozone and erosion-resistant ability to terpolymer EP rubber as major ingredient, has fabulous vulcanization characteristics; Zinc oxide helps accelerating vulcanization rate as activator, improves state of vulcanization; Anti-aging agent RD is provided by sea, Ningbo sharp chemical industry company limited, plays antioxidant effect, can suppress harsh oxidation, thermal ageing and weathering age; Paraffin wax 56# is complete, and refining is provided by China Petrochemical Maoming Oil-Refining Chemical Co., Ltd, and paraffin wax has lubrication as tenderizer to rubber, can improve product appearance, improves the anti-ozone of product, water-fast and anti-day performance such as photoaging; Stearic acid plays softening and activatory effect as tenderizer in sizing material, good to the dispersing property of other Synergist S-421 95; Silane coupling A-172 helps improving the physical strength of superpolymer, and can improve processing characteristics as the usefulness of coupling between inorganic fillers and the high-polymer molecular; Superfine talcum powder (1250 order) can increase the sizing material volume as weighting agent, reduces cost, and is easy to disperse in sizing material, improves processing performance; Calcium powder (800 order) can increase the sizing material volume as weighting agent (Paris white), reduces cost, and is easy to disperse in sizing material, improves processing performance, can improve the product mechanical property; Calcinated argil has good thermotolerance as strengthening agent, and tensile strength and tensile modulus are easy to processing than higher; White carbon black as strengthening agent can make rubber have high wear resistance, pull apart brute force, performances such as anti-tear power and fixed stretching strength; Valelinum Liquidum (100#) helps the dispersion of Synergist S-421 95 in sizing material as tenderizer, and the effect that increases viscosity is arranged, and can improve the product processing characteristics; Vulcanizing agent DCP (dicumyl peroxide) improves the chemical structure of rubber as vulcanization system by sulfidation; Linking agent TAIC (C

3) iso-cyanuric acid triallyl ester effectively improves resistance toheat by improving the peroxide vulcanizing system cross-linking density.
The present invention has following beneficial effect: the present invention by adjusting composition of raw materials, has reduced raw materials cost by adopting technique scheme, and adjusted cable has reached the requirement of regulation with insulation rubber.Experimental data shows that aging preceding tensile strength reaches 8.5N/mm
2, aging preceding elongation at break reaches 350%.And can make that product has that chemical stability is good, ageing-resistant, wear resistance, elasticity, oil-proofness, electrical insulation capability and anti-ozone sends out and advantage such as can give prominence to.
Embodiment:
In implementing process of the present invention, we reach the performance of relevant Synergist S-421 95 and the demonstration that technical indicator has been carried out science to the major ingredient of prescription, especially by our test repeatedly, the result shows, use the present invention when improving the quality of products, also can reduce product cost, improve the product use properties, thereby obtain higher economic and social benefit.
Cable sees the following form 1 with the proportioning raw materials and the experimental result of insulation rubber:
Table 1
In sum: ethylene-propylene rubber(EPR) is that main raw material(s) is synthetic with ethene and propylene.And be that a kind of cable of main raw material is filled a prescription with insulation rubber with ethylene-propylene rubber(EPR), proportioning by science, make its use insulating material as cable in cable, its chemical stability is good, ageing-resistant, wear resistance, elasticity, oil-proofness, electrical insulation capability and anti-ozone are sent out and can be given prominence to, cable goods price is lower, is the first-selection of electric wire, cable sheathing and high pressure, ultra-high voltage insulating material.
