The structure and inflammability of the polymer composite coatings for bulk floors

The issues of construction of dispersion-filled polymer composite materials (DFPCM) structure, its description using the theory of lattices, packages and generalized parameters and their relationship with the inflammability of polymer floor coatings on a noncombustible base under the influence of a heat flux of various density are considered. For the first time, the fundamental dependences of the critical surface heat flux density (CSHFD) of DFPCM bulk floors based on epoxy and polyurethane matrices and inert filler (silicon dioxide) on the generalized structure parameters and lattice parameters have been established. The parameters of structure and composition of DFPCMs to obtain a liquid polymer bulk floors by traditional technology have been determined. These DFPCMs have inflammability not higher than B2, so they are moderately flammable, i.e. non-flammable when exposed to heat flux under test conditions according to GOST 30402-96, which corresponds to a CSHFD value not lower than 20 kWt/m 2 .
