Low volatilization eco PVC cable compounds and manufacturing process thereofTechnical field
The present invention relates to environment-friendly cable material, particularly relate to polyvinyl chloride cable material and manufacturing process thereof.
Background technology
Polyvinyl chloride (PVC) is as modal plastics in life, and being widely used in manufacturing various pvc pipe, PVC board, PVC film, PVC wallpaper, PVC cable material etc., is the class that in five large general-purpose plastics, purposes is the widest.
Polyvinyl chloride cable material is formed primarily of polyvinyl chloride resin, softening agent, stablizer, filler, modifier, lubricant and pigment, extrudes also granulation process through two steps type screw extrusion press.Wherein, the soft durometer of PVC cable material relies on the ratio of softening agent in PVC formula to regulate, and plasticizer loading is more, and CABLE MATERIALS is softer.Common CABLE MATERIALS selects the softening agent of some routines to carry out softening PVC, due to the characteristic of itself and the technique of production, the CABLE MATERIALS taste produced is heavier, more pungent, and the amount of being fuming is large, somatic damage is in various degree caused to a line operative employee of downstream cables production unit.Some CABLE MATERIALS due to the softening agent selected with low quality, cause the problem such as cable bleed, precipitation of production, cause product work-ing life to shorten, contaminate environment.
Current PVC plastic market, in order to ensure the living environment of the mankind, more and more harsher to environmental requirement, PVC plastic goods are except the Rohs environmental protection instruction of general requirement, also has European Union's REACH environmental regulation, EU Council 2007/47/EC instruction, European Union NO.10/2011 Food Contact regulation, in addition, trolley part comprises automotive line, and automotive upholstery etc. also make requirement, such as U.S. ASTM D3960-98 standard to PVC plastic smell and plastics volatilization, international standard ISO 4618/1-1998, moral mark DIN 55649-2000 standard etc.
