MODIFICATION OF COMPOSITE MIXTURES FOR MANUFACTURING SHIP CABLEWARE MATERIALS

The purpose of this work was to develop a modified polymeric composite mixture for the manufacture of the outer shell of a ship's cable operating under conditions of aggressive environment and increased fire hazard. The performed research resulted in the analysis of the basic polymeric composite mixtures. A complex of the most important technical and operational characteristics of the cable shell was formed. These characteristics are wear resistance, oil resistance and fire safety. On the basis of these assumptions a new polymer composition based on chloropolyethylene TYRIN CM 3630E with an increased oxygen index and improved physical and mechanical properties was developed. Modification of the mixture was carried out by increasing the mass fraction of flame-retardant additives and adding stabilizers to the mixture. Thanks to a balanced combination of technical and operational properties the use of the developed compound will increase the cable service life and operating time and will reduce the overall weight of the cable by using conductors of a smaller cross-section at a higher operating temperature.
