FLOORING CONSTRUCTING METHOD USING HIGH TEMPERATURE RESISTANT POLYURETHANE COMPOSITION

摘要

PURPOSE: A construction method of a floor material using a polyurethane composition with excellent heat resistance is provided to enable a floor material to have self-extinguishability even under a temperature of 700 degrees. CONSTITUTION: A construction method of a floor material using a polyurethane composition with excellent heat resistance is as follows. Primer is spread on the top surface of a floor material (S101). A flame retardant epoxy mixture with excellent abrasion resistance is spread on the top surface of the spread primer (S103). A glass fiber is loaded on the top surface of the spread epoxy mixture (S105). A flame retardant polyurethane composition is spread on the top surface of the loaded glass fiber (S107).
