Abstract
A disponibilidade de materiais de custo baixo, de origem renovável e com fornecimento constante podem gerar materiais com produtividade viável e com apelo ecológico. O papel é um subproduto de gráficas gerado nos processos de encadernação, furo e corte de todo tipo de materiais impressos. Este material é gerado em abundância e a custo praticamente zero. Devido a essas características e a sua origem renovável, o papel consiste em um material interessante
para o desenvolvimento de novos produtos. O aumento dos preços das resinas, principalmente das olefinas, associado a busca de materiais mais sustentáveis tem motivado os fabricantes a procurar alternativas que possam reduzir os custos e reduzir seu impacto ambiental. Logo, o desenvolvimento de um compósito de polipropileno (PP) e papel pode gerar materiais de menor custo e menor impacto ambiental, com funcionalidade adequada para utilização como placas separadoras, vacuum forming, chapas impressas e outros tipos de aplicações. Porém, devido a
incompatibilidade entre esses compostos, se faz necessário os uso de agentes compatibilizantes, permitindo a adesão entre as diferentes fases do compósito. Dessa forma, o presente projeto tem como objetivo avaliar a substituição de produtos de polipropileno (100%) por compósitos de polipropileno/papel. Para isso foi realizado um levantamento bibliográfico dos compósitos de polipropileno e/ou outras matrizes polioletíficas com papel e fibras naturais. Dessa forma, foram valiados os principais métodos de produção, compatibilizantes utilizados e alterações de propriedades.
The availability of materials at low cost, of renewable source and with constant supply can generatematerials with viable productivity and with an ecological appeal. Paper dust is a by-product of a printing company, generated in the processes of binding, boring, and cutting all kinds of printed materials. This material is generated in abundance and at virtually zero cost. Due to thesecharacteristics and its renewable source, paper is an interesting material for the development of new products. The increase in the prices of resins, especially olefins, associated with the search formore sustainable materials has motivated manufacturers to look for alternatives that can reduce costs and reduce their environmental impact. Therefore, the development of a polypropylene and paper composite can generate materials of lower cost and less environmental impact, withfunctionality suitable for use as separator plates, vacuum forming, printed plates, and other types of applications. However, due to the incompatibility between these compounds, it is necessary to use compatibilizing agents, allowing adhesion between the different phases of the composite. Thus, the present project aims to evaluate the replacement of polypropylene products (100%) by polypropylene/paper composites. For this purpose, a bibliographic survey of the polypropylene composites and/or other polyolithic matrices with paper and other loadsrelated to the same natural origin was carried out. The main production method, compatibilizers used andchanges in properties were evaluated.
