The temperature intervals of thermo-oxidative destruction of plasticizers were determined, taking polybutene aliphatic compounds as an example, the inverse dependence of their stability during thermal treatment on the value of molecular weight was established: low molecular plasticizers give the highest yield of non-volatile residue at carbonization
It was shown that the application of plasticizers makes it possible to change foam cell dimensions in a wide range: at an increase in the molecular weight, the plasticizer’s ability to affect the rheological properties of the system increases, which decreases the value of the average diameter of a foam cell by 1.5–2 times
Summary
Peremohy ave., 37, Kyiv, Ukraine, 03056 fire protection. In 2017, their market volume amounted to about USD 900 million, every year the market is growing by. Plasticizers are an additive that is widely used in the industry of paint and varnish coatings Their effect involves an increase in the mobility of macromolecular polymer chains, which leads both to a decrease in melting temperature of the material, and the change in viscosity of its melt. This makes plasticizers one of the effective regulators of the structure of fire-retardant foam, and, a means of improving the indicators of fire resistance of intumescent coatings. Lack of knowledge about the influence of plasticizers, in turn, leads to weak substantiation of the application of these components that are widely used in technological solutions
