Abstract

In our study, we investigated 2 different natural rubber mixtures with CNT’s and shoot. The aim was to compare the results of samples and their mechanical effects with a shore. A hardness tester, a tensile strength instrument before and after vulcanisation (t=30; 60; and 90minutes) during the UV-ageing processes. The hardness results represented the different after the degradation process that was 10 % different between the samples.

Keywords

Introduction

Elastomers have become a widely used technical material of our time. This is due, among other things, to the ability to produce significant reversible deformations of up to 100% by virtue of low tensions, and their mechanical and other properties can be altered in a universal spectrum by the correct selection of base materials and other ingredients. Their physical and mechanical properties can be greatly improved with – for example – fillers or reinforcing agents, and by adding the proper plasticizer they can be more or less easily used technologically. (e.g. acting as a slider). Although different additives play a key role regarding the properties of the finished rubber, the quantity and ratio of the additives cannot be freely altered since each component has a positive (soot as a filler improves abrasion resistance) effect, or greatly reduce certain properties (e.g. over-vulcanization with increased sulfur content):

Filler materials are isodynamic solid, matrix insoluble particle systems forming a separate solid phase. Their use has a remarkable past, and from the first quarter of the 19th century there are already references to the use of fillers in the caoutchouc. As a reinforcing filler, one of the largest quantities and the oldest used in the rubber industry are various soots. The most commonly used method for classifying them today is the 4-tag ASTM D1765 [1]. In the course of my investigations, we selected the 326 N type, in Table 1.
