Nano science and nano technology provides numerous opportunities for enhancing the properties of wood based panel products. In this study an extender was made using nano silicon dioxide ( Sio2), nano calcium carbonate( CaCo3) with some specialty chemicals at a certain reciprocal proportion. Efficacy study was carried out with both phenolic and amino resin in terms of rheological and formaldehyde emission test using reinforcement of nano additive as extender at different concentration level. The plywood panels has been tested as per IS: 1734-1983 for mechanical properties. The rheological and adhesive properties has been tested as per IS 848: 2006. The test data reveals that enhancement of rheological, bonding and mechanical properties have been achieved after reinforcement of synthetic resin. The increase in the percentage of nano-additive caused an increase of viscosity, glue shear strength and minimizing the formaldehyde emission than using individual nano silicon dioxide ( Sio2), nano calcium carbonate( CaCO3) instead of the extender made by combination of above. Using nano additive extender at 5%, there is an increase in glue shear strength in the glue line and enhanced rheological properties in amino resin based adhesive was observed.

The work concerned with studying the effect of (SiO2) addition as afiller on the adhesive properties of (PVA). Samples were prepared assheets by using casting method. The mechanical properties showedthat increase in tensile strength from (34MPa) to (68MPa) when(SiO2) added to (PVA). The adhesive strength showed that jointproperties depend upon specific adhesive characteristic of material(PVA) and (SiO2\PVA)composites at different concentrations (1.5%,2.5%, 3.5%, 4.5wt%), the cohesive strength of the adhesive material,the joint design, and adherent type (Sponge Rubber(SR), Naturalleather (NL), Vulcanized Rubber(VR), and Cartoon). The resultsproved the tensile strength increased with (SiO2) ratio, so it can beused as the adhesive material. Shear strength showed an increasewith (SiO2) ratio of sponge rubber, and cartoon adherent, whereas itwas increased up to 2.5% for Natural Leather, and VulcanizedRubber then decreased; That suggested it is most suitable for spongerubber adhesive and cartoon than the other adherents.

Abstract This work analyzed the effects of nano-silicon dioxide (nano-SiO2) fillers on the morphology and mechanical properties of acrylonitrile-butadiene-styrene (ABS)/poly(methyl methacrylate) (PMMA) blends. Nano-SiO2 particles were selectively dispersed in the PMMA phase, and the toughness of the ternary blends was significantly improved when the contents of the nano-SiO2 fillers were below 2 wt%. The stearic acid treatment of nano-SiO2 particles prevented the adhesion between constituents and markedly diminished the toughness of the blends. Nano-SiO2 particles were alternatively treated with a silane coupling agent to promote adhesion. The toughness was better in blends for filler contents below 2 wt% than in pure nano-SiO2 particles. However, the presence of nano-SiO2 fillers decreased the surface glossiness of the blends. This work provides new insights into the processes by which nanomaterials toughen ABS/PMMA blends.
