Pembuatan Genteng Polimer Berbahan Baku Pasir dan Limbah Padat Pulp Dregs dengan Perekat Resin Poliester

Abstract

The research has been done for manufacture of polymer tiles which is made with a mixture of sands, solid waste of a pulp dregs, polyester resin, and thinner. The purpose of this research is to find out the best of the mixture of sands and solid waste of pulp dregs as a free variables with composition (100:0) gr, (95:5) gr, (90:10) gr, (85:15) gr, (80:20) gr, and (75:25) gr. Then polyester resin 20 gr as adhesive and thinner 10 gr as diluent were added as a fixed variables. The mixture was pressed with hot compressor for 20 minutes in 90°C. Characteristics of tiles that have been analyzed which is the physical characteristics are density, water absorption, and porosity, and the mechanical characteristics are the power of impact and flexural strength, microstructural analysis which involve SEM-EDX test, and also thermal character is DTA test. The result of this research shows that the best test of the mixture was made from the mixture of sands and solid waste of pulp dregs with ratio (90:10) gr with the addition of 20 gr polyester resin as an adhesive, also thinner 10 gr and catalytic 0,3 gr.
