Abstract

Se realizó un estudio comparativo del efecto que produce la adición de agentes de acoplamiento tipo silanovinyltrimethoxysilano y 3-aminopropiltrietoxisilano sobre la mezcla de etilenvinilacetato con harina de TelinneMonspessulana. La incorporación de agentes de acoplamiento se hizo de manera directa sobre la mezcla empleando harina sin tratar y mercerizada. También se hicieron ensayos mezclando etilenvinilacetatoy harina injertada previamente con cada uno de los silanos. Los compuestos fueron sometidos a ensayos de tensión con el fin de evaluar los agentes de acoplamiento. Se encontró que la adición delsilano amino durante el mezclado de los compuestos aumentó la resistencia a la tracción, siendo un importante resultado pues estos son materiales livianos aplicables en la industria de construcción y automotriz.

Palabras claves: etilenvinilacetato, harina telinnemonspessulana, compuestos de plástico con madera, agente de acoplamiento silano, viniltrimetoxisilano, aminopropiltrietoxisilano.

Abstract

A comparative study the effect of the addition of silane coupling agents, vinyltrimethoxysilane and 3-aminopropyltriethoxysilane on ethylenevinylacetate and Telinnemonspessulana flour composites was performed. The silane coupling agents were added in the mixing stage of ethylene vinyl acetate and wood flour (untreated and mercerized). Tests were also made by mixing ethylenevinylacetate with previously grafted wood flour. Flour graft was performed with vinyltrimethoxysilane and 3-aminopropiltrietoxisilano. The compounds were tested for tensile testing to evaluate the coupling agents. It was found that the addition of amino-silane during mixing increased tensile strength, being this an important result since these are lightweight materials that can be used in the construction and automobile industry. Key words: ethylene-vinyl acetate, telinnemonspessulana flour, wood plastic composite, silane coupling agent, vinyltrimethoxysilane, aminopropyltriethoxysilane
