Abstract

Urea-melamine-formaldehyde (MUF) resin was synthesised and used as additive for preparing flame resistant composites. MUF resin synthesis conditions was convestigated by changing the ratio of raw materials. Some properties of resin such as viscosity, free formaldehyde content and storage time was investigated. The results of performance test showed that with F/(U+M) ratio of 1.5 and U/M ratio of 1.5, MUF resin was of low free formaldehyde content, long storage time and moderate viscosity. Composite materials was prepared with MUF resin, PS foam and other additives were of tensile strength of 2.3 Mpa, density of 0.95 g/cm3, degree of swelling in seawater of 1.8% and limitting oxygen index of 28, which was demostrated to be suitable using for fire-resistant panels.
