Abstract
The effect of modified natural zeolite of the Shivyrtuysky deposits on the thermal behavior of epoxy composites at the heating was studied. The modification of the zeolite particles with aluminum oxyhydroxide (AlOOH) nanofibers was made. AlOOH nanofibers were obtained at the heating and oxidation of aluminum powder by water. The parameters of thermal-oxidative and thermal destruction of the samples with a filler concentration of 1, 2, 5, and 10 wt. % were determined. The limiting oxygen index was determined by the calculation method.
Highlights
Epoxy polymers have a range of unique properties, such as ease of curing, low shrinkage during curing, high mechanical and electrical insulating properties, adhesive ability, chemical resistance [1, 2]
The flammability of epoxy resins can be reduced by the introduction of fillers with flame retardant properties into the epoxy matrix
Summary In our study, the zeolite based epoxy composites were fabricated with a content of the filler 1; 2; 5 and 10 wt. %
Summary
Epoxy polymers have a range of unique properties, such as ease of curing, low shrinkage during curing, high mechanical and electrical insulating properties, adhesive ability, chemical resistance [1, 2]. Epoxy resins are widely used in construction, mechanical engineering, electrical engineering, and other areas of production. There is a disadvantage that complicates the use of epoxy resins: their high flammability and increased fire hazard [3, 4]. The flammability of epoxy resins can be reduced by the introduction of fillers with flame retardant properties into the epoxy matrix. The use of traditional halogen-containing flame retardants based on bromine and chlorine leads to the formation of highly dangerous and persistent toxic substances, such as phosgene, cyanide compounds, dioxins. Researchers are attracted by fillers based on natural minerals that are not highly toxic, they are relatively cheap and widely distributed in nature materials [5,6,7]
