Abstract(s)
A produção de laminados de alta pressão (HPL) tem aumentado largamente devido à sua versatilidade de utilização, elevada resistência e baixo custo.
Os laminados podem ser utilizados em diversas aplicações verticais e horizontais, tais como decoração de interior, pavimentos e em diversos tipos de mobiliário.
Devido ao grande interesse neste tipo de produtos, a preocupação com a cura das resinas dos papéis que os constituem é constante. Este projecto tem como objectivo a avaliação da cura das resinas dos papéis constituintes de um painel de laminados de alta pressão.
Recorrendo a um equipamento de avaliação automática de colagem (ABES – Automated Bonding Evaluation System) foi realizado um estudo sobre o desempenho da ligação de papéis impregnados resultante da cura da resina. Foram estudados diferentes tipos de papéis – dois tipos de papel Kraft; quatro diferentes tipos de papel Decorativo; e quatro diferentes papéis Overlay.
Foram testadas diversas configurações de formação dos provetes de ensaio, para garantir uma maior fidelidade à formação de um painel de laminado em condições industriais.
Realizaram-se ainda estudos da rugosidade dos papéis para verificar, se a distribuição da resina utilizada na impregnação destes iria influenciar a consolidação do laminado de alta pressão.
ABSTRACT: High pressure decorative laminate (HPL) production has increase in the last years largely due to its wide range of application, strength and low cost. The laminate can be in a large number of applications, both in vertical and horizontal, such as interior decoration, flooring and several types of furniture. Due to the high demand on these products there is a major concern with the cure of the resins that impregnate the buildup papers. This project has as objective the evaluation of the cure of the resins that impregnate the high pressure decorative laminate buildup papers. Study on the performance of impregnated paper bonds due to resin cure was carried out using the equipment ABES – Automated Bonding Evaluation System. Different types of impregnated paper were studied – two types of Kraft paper; four different types of Decorative paper; and four different Overlay papers. Several test samples buildups were tried in order to ensure a better affinity with the HPL industrial buildup. Impregnated papers roughness was also evaluated in order to verify if the resin distribution has an impact on the high pressure decorative laminate consolidation.
