摘要

The paper overviews the process of thermolysis of fire-retardants based on melamine, ammonium polyphosphate and pentaerythtritol and containing titanium dioxide of different trademarks. The role of titanium dioxide as a component of fire-retardants is revised. Titanium dioxide was perceived only as white pigment, but this paper states that the properties of a charred layer forming from an intumescent coating depend on the properties of titanium dioxide's species, such as surface treatment and crystalline structure. This statement is proven by using thermal analysis of intumescents with different titanium dioxide's trademarks; it shows that rutile titanium dioxide helps forming a charred layer with the highest thermal stability thus fire retardant efficiency grows up. It means that the knowledge of processes which occur in intumescents based on primary products with different qualities helps to create fire-protective compositions which will perform more reliable in case of fire.
