Preparation and Characterization of Composites Materials with Rubber Matrix and with Polyvinyl Chloride Addition (PVC)

Abstract

An important problem that arises at present refers to the increase in performances in the exploitation of the conveyor belts. Additionally, it is pursued to use some materials, which can be obtained by recycling rubber and PVC waste, in their structure. Thus, the research aimed at creating conveyor belts using materials obtained from the recycling of rubber and PVC waste. Under these conditions, conveyor belts were made that had in their structure two types of rubber and PVC, which was obtained by adding in certain proportions of reclaimed rubber and powder obtained from grinding rubber waste. In order to study the effect of adding PVC on properties, four types of conveyor belts were made, with the structure of rubber, PVC and textile reinforcement. These have been subjected to certain mechanical tests, also being analyzed from the point of view of the behavior of the accelerated aging. The results obtained showed that the addition of PVC lead to a decrease in tensile stress for the strips made, but also an increase in the tensile strain. Additionally, the elasticity tests performed before and after the accelerated aging showed that the presence of PVC in the structure of the conveyor belts determined a substantial reduction of the aging process of the rubber in the conveyor belts. Under these conditions, it has been established that the use of PVC in the structure of rubber matrix conveyor belts is beneficial if conveyor belts are to be produced that are less subject to mechanical stress, but that work in conditions that can cause accelerated aging of materials. An analysis with the finite element method (FEM) of the test samples was also performed.

A Brief Review of Poly(Vinyl Chloride) (PVC) Recycling

“…For pulverised materials, hydrocyclones can be used [ 56 ]. PVC raw material obtained from the recovery process can be successfully processed into a number of new products, in particular polymer composites [ 57 , 58 , 59 , 60 , 61 ].…”

Surface Evaluation of Gyroid Structures for Manufacturing Rubber–Textile Conveyor Belt Carcasses Using Micro-CT

“…Therefore, suitable materials should be identified for use in additive technologies to produce textile carcasses for conveyor belts. At present, different types of materials are commercially available with the potential to be applied in the additive production of rubber–textile conveyor belt carcasses [ 17 , 18 ]. The ability of existing additive technologies to produce a structure that can outperform traditional conveyor belt carcasses should be verified before further analysis.…”

A practical manner to GTR recycling in waste-HDPE/ABS

“…Effective disposal of waste ground tire rubber (GTR) represents a significant and urgent issue all around the world for quite long time and it is striking a balance among economical, ecological and technical factors in the recycling process by having huge impact on the outcomes [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Blending of polymers and rubbers can be an alternative way to create new type of polymer materials and it plays an important role in the field of both polymer and rubber recycling as a possible solution [2,11].…”
