Abstract

Fire-retardative property given on coating materials by mixing a chlorination product of fish oil therewith was examined by comparing a combustion curve of a wooden test plate, which had been painted with test paint, with that of a control plate. Combustion curves were obtained by observing the time required to bring about inflammation of wooden plates heated at specified temperatures. As shown in Fig. 4, it is obvious that coating materials, except boiled oil, mixed with the chlorination product are fire-retardative at heating temperatures lower than about 450°C. In the case of boiled oil and when heating temperature was higher, test plates began to burn in shorter time than control plates did. But combustion of test plates was gentle, and the flame was dim and not persistent, disappearing as soon as the heating of the plates was stopped. On the contrary, combustion of control plates was vigorous and continued even after the heating was stopped. Therefore, the chlorinated fish oil will probably be used with effect for conferring fire-retardative property on ordinary paint.
