Compatibilized Blends

AbstractWaste tire rubber is commonly recycled by blending with other polymers. However, the mechanical properties of these blends were poor due to lack of adhesion between the matrix and the waste tire rubber. In this research, the use of electron beam irradiation and (3-Aminopropyl)triethoxy silane (APTES) on enhancing the performance of 50 wt% reclaimed tire rubber (RTR) blend with 50 wt% poly(ethylene-co-vinyl acetate) (EVA) was investigated. Preparation of RTR/EVA blends were carried out in the internal mixer. The blends were then exposed to electron beam (EB) irradiation at doses ranging from 50 to 200 kGy. APTES loading was varied between 1 to 10 wt%. The processing, morphological, mechanical, and calorimetric properties of the blends were investigated. The stabilization torque and total mixing energy was higher in compatibilized blends. Mechanical properties of RTR/EVA blends were improved due to efficiency of APTES in further reclaiming the RTR and compatibilizing the blends. APTES improved the dispersion of embedded smaller RTR particles in EVA matrix and crosslinking efficiency of the blends. Calorimetric studies showed increased crystallinity in compatibilized blends which corresponds to improved mechanical properties. However, the ductility of the blend was decreased due to increased interaction between EVA and APTES. Presence of APTES increased the efficiency of electron beam irradiation induced crosslinking which was shown through gel content analysis and Charlesby-Pinner equation.

Abstract This article aims to perform statistical analysis on the inclusion effects of waste tire rubber and fly ash from thermoelectric plants as mortar components for coating buildings. Reference mortars and mortars containing 5% and 10% rubber with a maximum grain size of 0.71 mm and mortars containing fly ash particles with a diameter of 45 μm were produced. Mortars containing rubber replaced 5% and 10% of the fine aggregate mass by this material and fly ash was added in 10% and 20% proportions compared to the cement volume. A 3² factorial experiment was performed on the mechanical properties of the compressive strength of mortars, applying analysis of variance (ANOVA) and surface response. The rubber waste material contributed to the decrease in compressive strength of the mortar and that factor displayed the highest significance in the response variable.

Effect of waste tire rubber particles (WTRP) and glazed hollow beads as an aggregate on mechanical properties and thermal conductivity of thermal insulting mortar was studied. Several mortar mixtures were prepared by keeping the accumulated volume of both WTRP and glazed hollow beads equal to 1 m3and by using WTRP contents of 0, 125, 250, 375 and 500 (its accumulated density) kg/m3respectively. Results indicate that dry bulk densities of the mortars containing WTRP are all less than 900 kg/m3. The mortars or the WTRP have a certain hydrophobic property. The 28 d compressive strengths of the mortars are 1.4~2.0 MPa. And the thermal conductivity values are 0.095~0.139 W/(m.K) increased with the WTRP content increasing. The results suggest that the mortars containing WTRP as a part of an aggregate can be used as thermal insulating material.
