Investigation on Eco-friendly Waterborne Intumescent Flame-retardant Coatings for Steel Plate via ANOVA Based on D-optimal Design Method

Abstract

Optimizing the formulations for a preparation of eco-friendly waterborne intumescent flame-retardant coatings(IFRC) requires the fire resistant effectiveness of several fire retardants combinations to be determined. In this study, three fire retardants were tested: ammonium polyphosphate, pentaerythritol and melamine. Their fire resistant effects were evaluated using the fire-resistance tests of the International Organization for Standardization (ISO). A D-optimal mixture design was used to provide a maximum of information from a limited number of experiments. The main objective of the research presented here was to carry out multivariate analysis of variance(ANOVA) upon data from the experimental design based on Design Expert® software. The results of this investigation were analyzed with the help of the software and enabled us to formulate coatings satisfying requirements of the ISO 834-1:1999.
