Improving the flame retardancy of marine composites

hindering the application of composites in the maritime sector is the problem of its flame retardancy and completely cleaning the oil tank. Italian researchers are studying how to obtain beneficial flame retardancy by adding zinc based compounds to epoxy matrix

in the United States, federal regulations also prohibit the use of composite materials in the main structure of ships, because it has not reached the non combustion requirements. BASF, Huntsman, Bayer and other international chemical giants have increased their efforts to expand the Chinese market. In contrast, the high speed ship (HSC) code of the international maritime organization accepts that composite materials can be used as a component of flame retardant materials for cabin linings and bulkheads because it performs satisfactorily in combustion tests

at a recent meeting organized by Rina (the Royal Society of Naval Architects), IMCB composite Research Institute and CNR national Biomedical Research Council emphasized in their report that beneficial resistance protection and maintenance: Flammability can be obtained by adding zinc based compounds to epoxy. Author de fenzo checked all -->, Formicola, antonnucci, zarrelli and Giordano pointed out that the unmodified epoxy resin ignited at 400 ℃, and then decomposed to form coke to produce a large amount of harmful smoke, which is due to the large amount of flammable and volatile substances contained in the resin

it is known that some zinc and tin compounds can effectively inhibit these harmful fumes. They do this by slowing down the combustion process, making it "segmented", which has a higher carbon yield than pure resin. Therefore, less material can be turned into smoke. Tests conducted in Italy showed that zinc borate, zinc stannate and zinc hydroxide stannate were used as additives for low viscosity toughened epoxy resin, which was used for resin transfer molding (RTM) and vacuum pouring. They have proved to be effective flame retardants. Its degradation process model has been developed

a flame retardant document on fiber reinforced plastic yacht structures (FRP) submitted by ABS, a branch of British Bureau of shipping, outlines a theoretical model for predicting the performance of a composite component under a specified heat load. The successful verification of the model in the actual combustion test will help to formulate the standard draft to help designers provide effective protection when the resin is on fire and harmful gas emissions after fire.
