Polymeric mortar made with unsaturated polyester hybrid resin (frompost-consumer PET bottle recycling) with silane nanocoupling

Abstract

Post-consumer PET bottles were mechanically and chemically recycled to synthesize unsaturated polyester hybrid resin UPR-H), with the addition of silane nanocoupling (AS), used in the preparation of polymeric mortars (PM), which are a mixture of fine aggregates and polymer (binder). The RPI-H is the binder and the AS enhances the UPR-H/aggregate chemical interaction.
AS-modified MP (PMM) was made; RPI-H was synthesized in a Vessel-type reactor, varying the temperature from room temperature to 180 ºC, with the addition of propylene glycol, zinc acetate, maleic anhydride and styrene and 3-(trimethoxysilyl)propyl methacrylate (TMSPM), as AS. PMM was obtained and characterized by Fourier transform infrared spectrometry (FT-IR) and compressive strength. The results obtained confirmed that the PMM was obtained and the chemical interaction in the ZTI of the PMM was achieved through the coupling agent TMSPM,
due to its characteristic molecular bonds found (FT-IR) and the compressive strength of the PMM increased in 45% compared to that of the PM.
