Abstract
The invention relates to a wear-resistant nitrile-butadiene rubber modified polyvinyl chloride sheath material for communication cables, which is prepared from the following raw materials in parts by weight: 65-70 parts of polyvinyl chloride, 20-25 parts of nitrile-butadiene rubber, 4-5 parts of high-wear-resistance carbon black, 2.5-3 parts of triallyl isocyanurate, 0.3-0.6 part of dicumyl peroxide, 5-6 parts of ultra-high molecular weight polyethylene, 3-4 parts of carbon nanotube, 0.6-0.8 part of nano silver particle and 0.2-0.3 part of zinc diethyl dithiocarbamate. The polyvinyl chloride and nitrile-butadiene rubber are subjected to secondary crosslinking compounding without vulcanization, thereby greatly simplifying the tool set equipment and technique, enhancing the efficiency and lowering the cost; and thus, the sheath material has high strength and favorable oil resistance, and has better softness and elasticity than the single use of polyvinyl chloride. The carbon nanotube and nano silver particle are utilized to enhance the tensile strength, wear resistance and corrosion resistance of the sheath material. The ultra-high molecular weight polyethylene is utilized to enhance the wear resistance and moisture resistance of the sheath material.
Description
Technical field
The present invention relates to cable jacket material field, particularly relate to a kind of wear-resisting communication cable acrylonitrile butadiene rubber modified pvc sheathing compound and preparation method thereof.
Background technology
Rubbercable is soft with it, there is elasticity, rub resistance and in being widely used in, among the electric power circuit of the frequent movement of the need of low pressure, such as shipboard cable, subway cable, mine electric cable, welding machine cable, studio cable etc. plastic cable is then superior with its electric property, physical strength is high and be widely used in middle high-pressure, among the electric power circuit fixedly laid, in each comfortable each department of national economy, play extremely important effect.In the middle of plastic cable, although cross-inked polyethylene power cable obtains significant progress in recent years, but polyvinyl chloride insulation, polyvinyl chloride boot power cable are still playing an important role, especially in the middle of low-voltage circuit, polyvinyl chloride (PVC) electric wire, cable are still in occupation of dominant position. with regard to production technique, rubbercable and twisted polyethylene cable all more complicated, all need larger facility investment.Comparatively speaking, the production technique of polyvinyl chloride cable will be simply too much, and because it is without the need to sulfuration, facility investment is just much smaller, and production cost is just corresponding much lower.
In addition, the relative rubbercable of polyvinyl chloride cable, CABLE MATERIALS used can industrialized mass production, and rubber material is quite different, it can only be that cable producer is self-produced personal, and due to rubber material variety of raw material many, although also make troubles to production. polyvinyl chloride cable has unique advantage on producing, but with regard to purposes, it still cannot substitute rubbercable, reason is just the flexibility of polyvinyl chloride cable, elasticity cannot be compared with rubbercable.
According to the principle of rubber and plastic compound, " research of polyvinyl chloride-paracril compound elastomer cable material " one literary composition uses polyvinyl chloride and paracril to carry out compound, without the need to sulfuration, obtains elasticity, flexibility, CABLE MATERIALS that oil-proofness is good.But this matrix material just carries out simple compound, the performances such as tensile strength, resistance to air loss, moistureproofness, ageing resistance, wear resistance not, should can not meet the requirement of modern industry to communication cable, need to improve.
Summary of the invention
