Abstract
The invention belongs to the field of cable materials and particularly relates to a modified polyvinyl chloride cable material mainly prepared from the following raw materials in parts by weight: 100 parts of polyvinyl chloride resin, 20-25 parts of powdery acrylonitrile-butadiene rubber, 35-45 parts of plasticizer, 0.1-0.5 part of antiager, 40-50 parts of filler and 15-20 parts of modifier. The modified polyvinyl chloride cable material provided by the invention is modified by using the powdery acrylonitrile-butadiene rubber, and an anti-aging system and the modifier are added, so that the modified material has the double performances of plastics and rubber, is not needed to be vulcanized, can be extruded and molded by using a common plastic extruder and is simple in preparation method.
Description
Technical field
The invention belongs to cable material field, be specifically related to a kind of modified polyvinyl chloride CABLE MATERIALS and preparation method thereof.
Background technology
Therefore common polyvinyl chloride (PVC) sheath moulding process is simple, but polyvinyl chloride quality is harder, and wear-resisting not, conventionally can only be with non-moving occasion electric wire, cable insulation and/or the sheath of fixing.General Purpose Rubber CABLE MATERIALS, has softness, wear-resisting, thereby is widely used as mobile occasion electric wire, cable insulation and/or sheath.Yet rubber insulation and/or sheath moulding are higher to equipment requirements, equipment investment cost is large, and moulding process is controlled complicated, and not oil resistant, the not acid-and base-resisting of General Purpose Rubber CABLE MATERIALS.People are comprehensive rubber and polyvinyl chloride advantage, proposition is mixed and modified by both, as < < China plastic article is filled a prescription complete works of > > P101 openly, mixed and modified by 100 parts of PVC, 20-40 part paracril, 5-10 part activated Calcium carbonate, a certain amount of stablizer, prepare cable jacket material and Insulation Material.Yet only mixed and modified by PVC and paracril, the extrusion temperature of modifying material is higher, is unfavorable for extruding moulding, and modifying material surface-brightening, do not reach the matt matt effect of rubber surface.For reaching extinction effect, conventionally need adopt separately sand milling technique to imitate out the sub-light state of rubber outward appearance, subsequent technique is complicated; Also have and adopt to increase relatively large matting agent delustring, yet adopt separately, increase matting agent delustring measure, though can reduce luminance brightness, but can cause material loose, connectivity variation between mixture, intensity is low, and more difficultly extrudes moulding.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned prior art, a kind of have rubber property and surperficial matt effect are provided, the modified polyvinyl chloride CABLE MATERIALS that workability is good also provides its preparation method.
Particularly, contriver provides following technical scheme:
A modified polyvinyl chloride CABLE MATERIALS, is mainly prepared by following weight parts raw material:
100 parts of polyvinyl chloride (PVC) RESINS, Powdered acrylonitrile-butadiene rubber 20-25 part, softening agent 35-45 part, antiager 0.1-0.5 part, weighting agent 40-50 part, properties-correcting agent 15-20 part.
Polyvinyl chloride (PVC) RESINS in the present invention (PVC), as the base-material of CABLE MATERIALS, can adopt the common middle molecular weight polyisoprene vinyl chloride resin that is 1000-1300 such as molecular weight; Also can adopt the polyvinyl chloride resin with high molecular weight of 2500-4000, in the present invention, especially to adopt polyvinyl chloride resin with high molecular weight for well, be conducive to improve the flexibility of improving CABLE MATERIALS.Powdered acrylonitrile-butadiene rubber is mainly as modifier, due to advantages such as its dispersiveness, ease for operation, particle refinements, for modified PVC resin, paracril is applied the flexibility that can increase CABLE MATERIALS in electric wire sizing material, improves goods oil resistant, cold-resistant and wear resisting property.Softening agent, is mainly the molten glass state temperature that reduces resin, increases Resin Flow, is beneficial to extrusion moulding.Stopping composition, similar with common cable filler, can all adopt activated Calcium carbonate, to reduce costs.The present invention adopts compound antiager system, more can guarantee the anti-aging and oxidation proof properties of CABLE MATERIALS.Properties-correcting agent adopts high-low temperature resistant properties-correcting agent, can more optimize improved materials performance.
As preferably, in the present invention, described softening agent is trimellitic acid ester plasticizer.As trioctyl trimellitate (TOTM) etc.
As preferably, in the present invention, described antiager is the equal amount of mixture of Hinered phenols antioxidant, hindered amine light stabilizer and metal passivator.Hinered phenols antioxidant is selected antioxidant 1010, anti-oxidant DLTP etc.Hindered amine light stabilizer is photostabilizer LS-770 etc.Metal passivator is copper(greening)inhibitor, as m-nitro formyl hydrazine etc.
As preferably, in the present invention, described weighting agent is ultrafine active heavy calcium carbonate, and its granularity is more than 3000 orders.
As preferably, in the present invention, described properties-correcting agent is ethylene vinyl acetate carbon monoxide terpolymer.
The present invention also provides the preparation method of above-mentioned a kind of modified polyvinyl chloride CABLE MATERIALS, comprising: in kneader, add each feed composition, 90 ~ 100 ℃ of temperature controls, stir, and send into extruding machine, and 140 ~ 170 ℃ of temperature controls, plasticizing is extruded, granulation, making articles.
Compared with prior art, the present invention also has the following advantages:
Modified polyvinyl chloride CABLE MATERIALS of the present invention, adopt Powdered acrylonitrile-butadiene rubber modification, and add antiaging system and properties-correcting agent, make CABLE MATERIALS there is the flexibility of rubber, good feel and matt effect, simultaneously, mechanical-physical and the chemical property of CABLE MATERIALS have also been improved, the feature with oil resistant, wear-resisting, acid and alkali-resistance, makes modifying material have the dual property of plastics and rubber, does not need sulfuration, as long as just can extrusion moulding at common plastics forcing machine, preparation method be simple.
Embodiment
Below in conjunction with embodiment, be described more specifically content of the present invention.It should be pointed out that embodiment is only the more representational example of the present invention.Obviously, technical scheme of the present invention is not limited to following embodiment, can also have many distortion.Every all distortion of directly deriving or associate from content disclosed by the invention, all should think protection scope of the present invention.
