Effect of Cleaning Agent on Tensile and Swelling Properties of Natural Rubber Latex Film

The effect of different types and loading of cleaning agent on the tensile properties and swelling properties of natural rubber latex film were investigated. The aim for this study is to find the cleaning agent which is compatible with natural rubber latex with optimum loading. In this study, there are two different amine based cleaning agent used which are Monoethanolamine (MEA) and Di-(3-aminopropyl) ether of diethylene glycol (DG). Swelling test was done to support the tensile results. It is found that tensile properties of the sample with MEA cleaning agent is higher than control sample (without cleaning agent) and sample with DG cleaning agent. For the best cleaning agent compound, the different loading has been tested and results showed that optimum loading of cleaning agent are achieved at 5 phr. The effects of both types of cleaning agents and different loading of cleaning agents on tensile properties and swelling properties for cleaning mold application are discuss.

Different Thickness

Laminated natural rubber latex with cleaning agent and waste latex compound was prepared by arranging half-cured latex sheets with various thicknesses of core layer then moulding using hot press according to the Rheometer graph. Laminated layers consist of outer layer (natural rubber latex films with cleaning agent) and core layer (waste natural rubber latex film). The core layer and outer layer are prepared through casting method with different thickness. For core layer, three different thickness of film is cast and for outer layer the thickness is control. The aim of this paper is to study the effect of different thickness of core layer and the different molding temperature on tensile and swelling properties of laminated films. The tensile test was carried out to acquire good interfacial adhesion between the laminates films. The fractured surface morphologies were carried out using digital microscope (Dino-Lite) to understand the interfacial interaction between core and outer layer of the films. The use of NRL lamination films with NRL waste will contribute to novel materials for as mould cleaning product with green and easier cleaning compare to conventional cleaning process.

Control Film

A range of radiation vulcanised natural rubber latex (RVNRL) films were prepared using various concentrations of aqueous extracts of mature Diospyros peregrina fruit, which acted as a cross-linking agent. The surface of the RVNRL films exhibited an aggregated morphology of the rubber hydrocarbon with increasing roughness due to increasing fruit extract contents in the latex. An improvement in tensile strength, tensile modulus, and storage modulus of RVNRL films was observed with the addition of fruit extracts compared to the control film due to their cross-linking effect. The glass transition (Tg) temperature of all the RVNRL films was found to be at around −61.5°C. The films were also observed to be thermally stable up to 325°C, while the maximum decomposition temperature appeared at around 375°C. The incorporation of fruit extracts further revealed a significant influence on increasing the crystallinity, gel content, and physical cross-link density of the RVNRL films.

Cleaning Agents

Natural Rubber (NR) latex cleaning compound was prepared by using three types of NR latex; HA latex, waste latex and subnormal latex. Each of these NR latex is then compounded with two different cleaning agents; monoethanolamine (MEA) and diethylene glycol (DEG) at three different phr loading; 1, 3 and 5 phr. The mechanical properties of these compounds were also investigated. Cleaning efficiency was conducted by applying the NR latex cleaning compound on the dirty surfaces. From the results, NR latex compounded with MEA exhibit better mechanical properties at loading of 3 phr MEA. The cleaning efficiency also showed the ability of NR latex compound to clean the dirty surfaces with addition of cleaning agent especially at higher loading. The waste N R latex compound compounded with MEA shows the best result in cleaning the surfaces due to the presence of filler that can adsorbed the dirt on the surfaces.
