MAgPP an Effective Coupling Agent in Rice Husk Flour Filled Polypropylene Composites

Different properties (tensile strength, elongation, modulus, impact strength) of rice husk (RH) reinforced polypropylene (PP) coupled by Maleic-Anhydride grafted Polypropylene (MAgPP) have been investigated. MAgPP is an effective coupling agent, not only in cellulosic-fibre filled polyolefine composites, but in rice husk flour filled polypropylene composite systems as well. It gives a utilizable construction polymer matrix composite (PMC) material even at a 40 wt.% RH filling degree. The strength and modulus increases by adding the rice husk but the elongation decreases in a non-monotonic way. Micrographs shows weak coupling in between RH and PP without MAgPP.

Abstract Abundantly available rice husk can be used with polypropylene for the development of thermoplastic composites. The present study deals with mechanical properties such as hardness and impact strength of rice husk polypropylene composites with the addition of talc, mica, CaCO3, wollastonite, and zirconium oxide. Maleic anhydride polypropylene was used as compatibilizer. Improvement in the hardness and impact strength of the composites was observed by the use of these additives. Possible applications of rice husk polypropylene composite are in building and automobile sectors.

Abundantly available rice husk was used to reinforce polypropylene for the development of rice husk polypropylene composites (RHPP) by extrusion and compression molding techniques. Maleic anhydride polypropylene (MAPP) compatibilizer and titanate coupling agent were used to improve the adhesion between rice husk and polypropylene. Effect of fillers such as mica, talc, zirconium oxide, silica and calcium carbonate on thermal properties of RHPP composites was studied. Improvement in heat deflection temperature (HDT), degradation temperature of RHPP was observed but enthalpies of melting and degradation decreased by the addition of these fillers. No significant change in melting point of composites was noticed by the addition of these fillers. Composites thus prepared to have applications in building, automobile, and sport sectors.

Properties Of Composites

The different coupling agent is used for diatomite modification. The diatomite with different content are melt and mixed with polypropylene to prepare diatomite/polypropylene composites. The modification effects of different coupling agent on diatomite and the influence of agent and diatomite contents on crystallization behavior of polypropylene and mechanical properties of composites are investigated. The results show that different coupling agents have the modification effects on diatomite influence crystallization of polypropylene but the aluminum agent is better than other agents. With the increase of the content of aluminum acid ester coupling agent, the size of bubble pore is uniform, and then the compressive strength reaches to a maximum when aluminum acid ester coupling agent content is 1%. With the increase of the content of diatomite, the porosity of bubble pore of diatomite/polypropylene composite material is gradually increases. The crystallinity of polypropylene and yield strength reach to a maximum (48.15% and 21.5%) when diatomite content is 30%. In addition, the diatomite/polypropylene composites have better compressive strength than the others.
