Resumo: The aim of the study was to develop technology for generating panels with MDF residues and gelatinized, chemically and physically modified corn starch. In the research, corn starch and sawdust MDF processing residues were used for panel formation and comparison with characteristics of commercial MDF. To support the study, the Brazilian standard ABNT NBR 15316-1 was used as a standard. As for the methodologies, treatments with lactic acid, acetic anhydride and by annealing technique were applied to change the properties of corn starch for later formation of the adhesive. The panels were formed in the cold and hot pressing process and physical tests were carried out to compare with the conventional MDF board and chemical tests to check the starch modification. The chemically modified starches underwent changes in their structure, compared to the starch in natura. The plate formed by sawdust and unmodified corn starch showed better parameters in comparison with the plates formed with sawdust and modified corn starch resisting the perpendicular traction of 5.95 kg / cm². It was observed that, although the boards produced by fresh corn starch have a lower resistance capacity than the usual MDF boards, they are alternatives to use part of the residue generated for a more noble application and that the adhesive has proved effective in forming the panels and eliminate possible substances undesirable to the environment.

En la investigación, se utilizaron residuos de procesamiento de MDF de almidón de maíz y aserrín para la formación de paneles y la comparación con las características comerciales de MDF. Para respaldar el estudio, se utilizó como estándar la norma brasileña ABNT NBR 15316-1. En cuanto a las metodologías, se aplicaron tratamientos con ácido láctico, anhídrido acético y mediante técnica de recocido para cambiar las propiedades del almidón de maíz para la posterior formación del adhesivo. Los paneles se formaron en el proceso de prensado en frío y en caliente y se realizaron pruebas físicas para comparar con el tablero MDF convencional y pruebas químicas para verificar la modificación del almidón. Los almidones modificados químicamente experimentaron cambios en su estructura, en comparación con el almidón en la naturaleza. La placa formada por aserrín y almidón de maíz sin modificar mostró mejores parámetros en comparación con las placas formadas con aserrín y almidón de maíz modificado resistiendo la tracción perpendicular de 5,95 kg / cm². Se observó que, si bien los tableros producidos con almidón de maíz fresco tienen una menor capacidad de resistencia que los tableros MDF habituales, son alternativas para utilizar parte del residuo generado para una aplicación más noble y que el adhesivo ha demostrado ser efectivo en la formación del paneles y eliminar posibles sustancias indeseables para el medio ambiente.                 O objetivo deste estudo foi desenvolver tecnologia de formação de painéis com resíduos de MDF e amido de milho gelatinizado, e modificado quimicamente e fisicamente. Na pesquisa utilizou-se amido de milho e resíduos de processamento de placas de fibra de média densidade – MDF, em forma de serragem para formação de painéis e comparação com características do MDF comercial.  Para suporte ao estudo utilizou-se como padrão, a norma brasileira ABNT NBR 15316-1. Quanto às metodologias, tratamentos com ácido lático, anidrido acético e por técnica de annealing foram aplicados para alterar as propriedades do amido de milho para posterior formação do adesivo. Os painéis foram formados no processo de prensagem à frio e à quente e realizou-se testes de físicos para a comparação com a placa convencional de MDF e testes químicos para verificar a modificação do amido. Os amidos modificados quimicamente sofreram mudanças em sua estrutura, comparado com o amido in natura. A placa formada por serragem e amido de milho não modificado apresentou melhores parâmetros em comparação com as placas formadas com serragem e amido de milho modificado resistindo à tração perpendicular de 5,95 kg/cm². Observou-se que, embora as placas produzidas por amido de milho in natura tenham menor capacidade de resistência que as placas de MDF usuais, elas são alternativas para utilizar parte do resíduo gerado para aplicação mais nobre e que o adesivo se mostrou eficaz em formar os painéis e eliminar possíveis substâncias indesejáveis ao meio ambiente.Research, Society and Development2020-10-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/765710.33448/rsd-v9i10.7657Research, Society and Development; Vol. 9 No. 10; e8969107657Research, Society and Development; Vol. 9 Núm. 10; e8969107657Research, Society and Development; v. 9 n. 10; e89691076572525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/7657/8338Copyright (c) 2020 Gabriela Silva Spirlandelli; David Maikel Fernandes; José Roberto Delalibera Finzerhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSpirlandelli, Gabriela Silva Fernandes, David Maikel Finzer, José Roberto Delalibera 2020-10-31T12:03:23Zoai:ojs.pkp.sfu.ca:article/7657Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:30:19.058184Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
