Description

A kind of subzero 50 degree of PVC cable materials of ultralow temperature
Technical field
The present invention relates to cable manufacturing technology field, more particularly to one kind to have flame-retardant smoke inhibition effect, good impact resistance The subzero 50 degree of PVC cable materials of ultralow temperature.
Background technology
The base-material of electric wire is mainly PVC plastic, and PVC plastic is one of five big general synthetic plastics, is the current world On be only second to the second largest plastics variety of polyethylene.Because Corvic has good physical and mechanical properties, can be used for Construction material, packaging material, electronic material, daily necessities etc. are produced, are widely used in industry, agricultural, building, communications and transportation, Each field such as power telecommunication and packaging.Electric wire is industrial and agricultural production and the indispensable critical facility of the modern life, at me Occupy very important status in state's national economy, still, at present PVC cable cold resistance and low-temperature impact resistance compared with Difference, limit its application under cryogenic.
The conventional method for improving PVC cold resistance is obtained by adding cold resistant plasticizer, in general cold resistant plasticizer Have：DOA (dioctyl adipate), DOZ (dioctyl azelate), DOS (SA dioctyl ester), DIDA (two different certain herbaceous plants with big flowers of adipic acid Ester), and above-mentioned cold resistant plasticizer and PVC compatibility are bad, actually can only be as the extender plasticizer for improving cold resistance Use, its dosage is usually the 5~20% of primary plasticizer, and these cold resistant plasticizer generally existing volatility are big, oil resistivity And the shortcomings that poor heat resistance, limit the use of these plasticizer.Therefore, to the cold resistance and shock resistance of PVC cable material It is modified, is those skilled in the art's technical problem urgently to be resolved hurrily.
The content of the invention
The problem of present invention is in order to overcome traditional PVC cable material cold resistance and shock resistance difference, there is provided one kind has The subzero 50 degree of PVC cable materials of flame-retardant smoke inhibition effect, the ultralow temperature of good impact resistance.
To achieve these goals, the present invention uses following technical scheme：
A kind of subzero 50 degree of PVC cable materials of ultralow temperature, the subzero 50 degree of PVC cable materials of ultralow temperature by following parts by weight component Composition：120~150 parts of polyvinyl chloride, 20~40 parts of nitrile rubber, 15~30 parts of bis- substituted fatty acid acid amides of N, N-, anti-impact changes Property 5.2~10 parts of 30~45 parts of agent, 20~50 parts of dispersant and composite flame-proof synergist.
Because PVC material cryogenic property itself is poor, by adding plasticizer nitrile rubber and the substituted fatty acid of N, N- bis- Acid amides makes it become softness to change its cryogenic property, and the PVC cold resistant cable material for adding conventional cold resistant plasticizer can only achieve zero Lower 40 degree or so low-temperature impact test, and it is expensive, and the present invention uses polyvinyl chloride as base material, adds special cold-resistant increasing Agent nitrile rubber and special impact modifier are moulded, micelle is caused by mixing plasticizing, with PVC cables, considerably increases PVC The cold tolerance of CABLE MATERIALS, make it being capable of long-term work under extremely cold environment.The present invention adds special cold resistant plasticizer and anti-impact Modifying agent compounding use, the cold tolerance of PVC cable material is not only substantially improved, is also greatly reduced cost.The present invention is also logical Cross and add fire-retardant, smoke suppressing that composite flame-proof synergist improves PVC cable material, security performance is improved.
Preferably, the impact modifier is one kind in EP rubbers and acrylonitrile-butadiene-styrene copolymer Or two kinds.
Preferably, the composite flame-proof synergist is made up of the component of following parts by weight：2~3 parts of Organosilicon Polymers, 0.2~1 part of 0.5~1.5 part of zinc stannate, 1.5~2.5 parts of organo montmorillonite, 1~2 part of molybdenum base hydrotalcite and phosphoprotein.
Preferably, the Organosilicon Polymers are silicones, one kind in amido silicon oil and polysiloxane polymer or Two kinds.
Preferably, the molybdenum base hydrotalcite is by hydrotalcite and ammonium octamolybdate, in molybdenum trioxide and eight molybdic acid melamines One or more modified be made.
Preferably, the phosphoprotein is from milk, soybean, carry in the one or more in the plant roots of saponin(e and gummy Acquisition is taken, cost is low, wide material sources, green, and resource utilization is high.
Preferably, the dispersant is the alcohol ester of hydroxyl containing active end group, bis-stearamides, monoglyceride, in oleamide It is one or more of.
Therefore, the present invention has the advantages that：
(1) fire-retardant and smoke suppressing effect is good, and securely and reliably, cost is low；
(2) poisonous additive is free of, the phosphorus source using biological material as fire retarding synergist, improves resource utilization, it is more green Environmental protection；
(3) cold resistance and shock resistance are good, have broad application prospects.
