The Influence of Sodium Bicarbonate Loading as Blowing Agent on the Properties of Epoxy Foam

Abstract: This research studied the effect of sodium bicarbonate content on the properties of epoxy. Sodium bicarbonate (SB) was used as foaming agent to improve the properties of thermosetting epoxy resin. The samples of epoxy foam were produced using mixing method. Sodium bicarbonate was selected as blowing agent by reason of the environmental friendly and low cost concern. Mechanical, physical and morphology properties were done. Sodium bicarbonate content was varied at 5, 10, 15, 20 and 25 part per hundred (phr), re… Show more

“…Moreover, the amount bulk density were also decreased with the increasing amount of percentage treated FGD sludge. Thus, the addition treated FGD sludge in samples of porcelain formulation were affected the higher percentages porosity in Figure 5 of samples and reduced percentages of densification [7]. According to Ishak et al [8] which stated that, decreasing the densification has also resulted the decreasing in bulk density of samples which some were might burnt off during sintering process.…”

“…Since the 1940s, thermosetting epoxy resin composite foam (ERCF) has been manufactured, due to its heat stability, chemical resistance, electrical properties, mechanical properties, [1][2][3] shock-absorbing and insulating properties brought about by foaming, it is widely applied in fields such as electronic packaging, construction engineering, floating on the sea, and aerospace. [4][5][6] At present, the preparation methods of thermosetting ERCF are mainly focused on the chemical foaming method, physical foaming way, and hollow microspherefilled foaming strategy. [7][8][9][10][11] For example, Ma et al 12 prepared a new composite foaming agent by filling the cells of microporous silica with the chemical foaming agent 4,4 0oxobenzenesulfonyl hydrazide (OBSH), which can be used as both filler and foaming agent, and the ERCF can be easily produced by the decomposition of the foaming agent.…”

“…[36,37] While, the effect of high load of sodium hydrogen carbonate (SHB) can be seen in the range of 15-35 php. [35,38,39] There have been many different methods that correlate variables via polynomial functions such as global least square fitting (GLS), moving least square (MLSM) estimation, and local regression estimation. [40] Each one of them has its pros and cons, such as inaccurate determining of the dominant factors, misleading approximation, weak analysis of random values, and proliferation of guess function.…”
