The present paper is a study on the performance characteristics of organic-inorganic hybrid flame retardants. MDF plywood has been used, that are being used for the interior decoration of building structures, to make the samples for experiment according to the existing or non-existing treatment of organic-inorganic hybrid flame resistants. Later, the experiment on the measurement of flame retardant performance using a $45^{\circ}$ flammability tester and the experiment on the measurement of combustion characteristic using a cone calorimeter have been proceeded to confirm the performance characteristic of organic-inorganic hybrid flame retardants. From the result of experiments, it has been confirmed that both organic-inorganic hybrid flame retardants have merits of inorganic and organic substances, and that heat resistance, durability and adhesiveness have been largely improved. The performance on the flame retardant has also appeared with excellent effect such as the reduced generation of combustion gas and the decreased generation of smoke.

The development of flame retardants aims to prevent the spread of fire and reduce the casualties caused by flammable and toxic gases generated during the combustion of building materials used in the interiors of multi-use facilities. Flame material application provides flame resistance to a silica sol in an organic-inorganic hybrid material by flame retardant adhesive or coating by producing a sol-gel method. The conventional flame retardant materials, non-flame retardant material is applied with Halogen freeway. In particular, the basic physical properties of conventional adhesive coating improves the heat resistance, enhances the durability fire and heat, and expands the halogen free flame retardant of building materials.

In this study, a non-halogen type organic-inorganic hybrid flame retardant sol, which can impart flame resistance to synthesize silicate of inorganic material and silane coupling agent of organic material by a sol-gel method, were newly manufactured. The addition of flame retardant will prevent loss of life in a fire because smoke from the flammability of interior finishing materials used as the construction materials poses a major danger. The smoke density measurement standard based on flame retardant performance standards, experiments were conducted according to the test equipment and procedures of ASTM E 662. The non-flaming mode experiment and the flaming mode experiment were conducted to confirm the performance of the manufactured flame retardant sol. As a result, the manufactured flame retardant sol improved the physical properties and heat resistance of existing flame retardants, and decreased the smoke production of the fire. Therefore, it may be possible to reduce the damage caused by smoke and expand the applications to various interior finishing materials.
