The effect of zeolite particle modified by PEG on rubber composite properties

Abstract

The purpose of this paper was to investigate the surface modification of zeolite with polyethylene glycol (PEG) and the modified zeolite as a reinforcing filler partly replacing carbon black (CB) into rubber to prepare the rubber composites. The surface characteristics of zeolite modified by PEG and the unmodified zeolite were characterized by infrared (IR) spectroscopy and scanning electron microscopy (SEM). Moreover, the evaluations of the zeolite/rubber composite were carried out on characteristics such as tensile property, abrasion loss, and hysteresis heat generation with different amounts of zeolite and PEG. The results showed that the tensile strength and elongation at break of the composites were improved, and the abrasion and lag heat generation were reduced when 5 -8 phr zeolite modified by 3 wt% PEG was filled into rubber. These results indicated that the modified zeolite has a good compatibility and dispersion in rubber.

Effect of natural zeolite as substrate filler on the properties of NBR/EPDM blend

“…Whereas, 10 phr unmodified zeolite gives the highest elongation and tear strength. This is in accordance with previous studies which found that CB substitution with 8 phr zeolite produced the best tensile strength (Fang et al, 2015). The modification of zeolite which does not show an enhancement of the mechanical properties is possible because physical modification just minimizes the size but does not makes a better bond between zeolite and the rubber matrix.…”

“…Zeolites in nature are generally pure, easily available and inexpensive. It is widely used in the environmental, petroleum, chemical, and agricultural industries (Rianto et al, 2012;Wustoni et al, 2011;Fang et al, 2015). Nowadays, the zeolite is widely developed and investigated as a filler, such as for NR/NBR blend (Siriyong & Keawwattana, 2012), NBR (Petrova et al, 2015), NR (Pajarito et al, 2017).…”

“…It has good thermal resistance, high surface area and has the ability to absorb polymers. Because zeolite is a kind of silica (inorganic silica), so it can be used as rubber filler (Fang et al, 2015). However, research on the NBR/ EPDM rubber blend with zeolite as fillers is still limited, especially using modified zeolite.…”

Mixed Matrix Membranes prepared from polysulfone and Linde Type A zeolite

“…The possibility of incorporating polymers and inorganic components into a material has been explored since the early industrialization of the polymers. Insertion of inorganic materials as fillers in the system could improve optical and mechanical properties [9]. The development of inorganic chemistry in recent decades and the introduction of the concept of "organic-inorganic hybrid materials" combined with multi-functionalization [10] has allowed the development of custom products.…”
