Notice of Retraction Analysis on polyurethane flame retardant migration based on temperature

This paper is devoted to some studies on polyurethane flame retardant migration with temperature changes. According to characteristics of polyurethane flame retardant, a new method of data preprocessing is proposed based on Chauvenet criteria. A mathematical model is set up for analysis on polyurethane flame retardant migration with the ambient temperature and the roasting time changes. Regression analysis is taken advantage of linear transform to realize nonlinear regression by way of variable substitution. A nonlinear dynamic behavior of polyurethane flame retardant migration with temperature change is analyzed. The experiment results show that the mathematical model proposed is good fit with the behavior of polyurethane flame retardant migration on environmental temperatures and baking time changes.
