AbstractPolyvinyl butyral is used in safety glass interlayers, mainly in car windshields. Legislative regulations require a recycling of cars after their lifetime and therefore also their safety glass. This causes the availability of recycled polyvinyl butyrate (r-PVB) originated from safety glass interlayers. Due to deteriorated optical properties, such as the transparency, and unknown amounts of plasticizers, it is challenging to reuse the recycled material in new windshields. Therefore, it is of particular interest to find new fields of application for r-PVB, such as the usage as a textile coating. In this research, r-PVB was investigated as a material for yarn coating. Polyester and polyamide mono- and multifilament yarns were coated continuously with solely a polymer dispersion and with mixtures of crosslinking agent and polymer dispersion. Crosslinked r-PVB coatings showed enhanced properties toward abrasion and chemical resistance. Coatings without the crosslinking agent showed a diminished abrasion resistance and could be washed off with ethanol. Mechanical properties of the monofilaments were influenced by the r-PVB coating in general. However, varying concentrations of the crosslinking agent did not affect the mechanical properties.

Geopolymer Binder

Several years ago the study on modification of existing materials that have enhanced properties has gained prominence. In this scenario, the geopolymeric binders, currently widely used in the construction industry have emerged. Thus, this study aimed to evaluate the influence of alumina addition on the mechanical and thermal properties of metakaolin in geopolymer binder. The geopolymers were synthesized from mixtures of metakaolin/alumina and sodium hydroxide, pressed and characterized by diffraction of X-ray and differential thermal analysis and thermogravimetric. Two types of alumina were used in different amounts (14% and 7%) in order to evaluate the effect of the load binder obtained. It can be seen that the incorporation of alumina into the system caused an increase in strength of products obtained as well as a reduction in total mass loss of the sample , especially when the use of fine alumina.
