Research and fabrication of high hardness one component dipping paint based on maleicized tung oil and epoxy resin

Abstract

This work presented the fabrication of dipping paint with high hardness based on solid epoxy resin and maleicized tung oil used for protection of small caliber bullets. The influences of temperature, maleicized time, components ratios on the properties of the prepared paint were investigated in detail. The results showed that the optimal maleicization conditions of tung oil were: Maleic anhydride content of 20%, temperature of 230 ^oC, reaction time of 4 hours, and maleicized tung oil/epoxy resin ratio of 1,5/10 (by weight). The prepared paint was of a non-volatile matter content of 20 ÷ 23%, complete drying time at 150 °C of 1 hour; adhesion point of 1, impact strength of 50 kG.cm, and flexural strength of 2 mm.
