Polyvinyl Chloride plastisol and preparation method and application thereof
2016Co-Authors: Dong Weixing, Shen Aihua, Zheng XiaofengAbstract:The invention discloses a Polyvinyl Chloride plastisol and a preparation method and application thereof. The Polyvinyl Chloride plastisol is prepared from, by weight, 100 parts of PVC paste resin, 1-5 parts of epoxy resin, 0.1-3 parts of a curing agent, 30-100 parts of a plasticizer, 1-3 parts of a heat stabilizer, 5-40 parts of filler, 0.1-2 parts of a thixotropic agent and 0-10 parts of a diluent. The breaking strength of the obtained product can reach 4-6 MPa, and the elongation of the obtained product can reach 200-300%. The Polyvinyl Chloride plastisol can be used for preparing Polyvinyl Chloride films. According to the Polyvinyl Chloride plastisol and the preparation method and application thereof, the strength of a plastisol cured product is effectively improved without influencing the elongation of the plastisol cured product; by using the thermal decomposition curing agent, it is avoided that the epoxy resin is cured ahead of time.

Experimental Study of Space Charge Characteristics in Thin Films of Polyvinyl Chloride Nanocomposites
International Journal on Electrical Engineering and Informatics, 2015Co-Authors: A. ThabetAbstract:This paper aims to provide a view of a lively space charge accumulation in new Polyvinyl Chloride (PVC) nanocomposite thin films. Space charges in thin films of Polyvinyl Chloride nanocomposite insulation materials are done to distort the local electric fields and affect high-field conduction and breakdown phenomena, whatever, adding nanofillers to Polyvinyl Chloride changes their electrical ages. Thus, space charge characteristics have been investigated by pulsed electroacoustic (PEA) measurement system for thin thickness of Polyvinyl Chloride nanocomposite materials which filled with different separately nanoparticles like ZnO, TiO2, and Al2O3. This paper depicts that space charge accumulation in Polyvinyl Chloride nanocomposites differs with respect to type and concentration of nanoparticles.

Nanotechnology Effects on Space Charge Relaxation Measurements for Polyvinyl Chloride Thin Films
International Journal on Electrical Engineering and Informatics, 2014Co-Authors: Osama El-sayed Gouda, A. Thabet, Youssef A. Mobarak, Mohamed Samir, Upper EgyptAbstract:Space charge accumulation in insulation materials indicates to conduction current through a dielectric material and it is important to know as well as possible the amount of charge stored in the dielectric. In this research, space charges tests aredone to distort the local electric fields, high-field conduction and breakdown phenomena in thin films of Polyvinyl Chloride nanocomposite insulation materials. Therefore, space charge characteristics have been investigated by pulsed electro-acoustic (PEA) system for thin thickness of Polyvinyl Chloride nanocomposite materials, which filled with different separate nanoparticles like Clay, and Fumed Silica, from the experimental tests carried out it is noticed that adding Clay and Fumed Silica to Polyvinyl Chloride changes its breakdown phenomena. Thisresearchaims to study the effects of types and concentrations of nanoparticles on space charge accumulation in Polyvinyl Chloride nanocomposites and illustrates which fillers that enhance Polyvinyl Chloride industrial applications.

Composition analysis and characterization of waste Polyvinyl Chloride (PVC) recovered from data cables
Waste Management, 2017Co-Authors: Sunil S. Suresh, Smita MohantyAbstract:Cables and wires are the indispensable parts of electronic equipments for transmission of both information and electricity. Nowadays, data cables are widely used in the computer equipments for sending information and they become waste once its life cycle is completed. However, recycling of cables and wires are mainly concentrating into the recovery of metals such as aluminium and copper, rather than other polymer present. Polymeric materials from the waste data cables are often disposed into landfills or incinerated, since they have only lower value in recycling yard. From the data cables collected, it has been estimated that the major constituents are copper (58.3%), Polyvinyl Chloride (19.9%) and polyethylene (16%). Similarly, polycarbonate (2.9%), silicon rubber (1.6%), steel (1.4%) and other material (0.4%) such as cotton cord were also present as minor components. Out of these, Polyvinyl Chloride is the dominant polymer present in data cables. Hence, the present work investigates the reprocessability of the Polyvinyl Chloride recovered from the data cables and deals with issues such as premature degradation during life cycle, assessment of plasticizers and degradation after reprocessing. Torque measurement studies using torque rheometer revealed further mechanical recycling possibilites of the recovered Polyvinyl Chloride. Besides, the applicability of melt blending technique for processing recovered Polyvinyl Chloride can be found out by analysing thermal behaviour by using thermogravimetric analysis, differential scanning calorimetry and heat distortion temperature.
