FIELD OF THE INVENTION [0001] The present invention relates to a semi-fireproof thermal insulation finishing material composition, a method of manufacturing the same,

More particularly, the present invention relates to a quasi-incombustible thermal insulation finishing composition, a method for manufacturing the quasi-incombustible thermal insulation finishing material composition, and a method of applying the same.

In general, insulation materials used in construction sites are a type of material used for the purpose of reducing heat loss to the outside, and besides the effect of insulation, it may also serve as an effect of sound insulation, buffering or reinforcement.

The heat insulating material is preferably a material having a low thermal conductivity, but most of the materials are not so small in heat conductivity, and in most cases, the heat insulating material is made porous so as to use the heat insulating property of the air in the pores.

Insulating material can be largely divided into organic and inorganic materials. Examples of organic materials include cork, cotton, felt, carbide, and rubber. Examples of inorganic materials include asbestos, glass wool, chrysotile cotton, diatomaceous earth, and magnesium carbonate Sponge, asbestos, glass fiber, etc., are widely used on the inner and outer walls of buildings, and foam panels such as styrofoam are used. In recent years, panels that strongly press small wood particles against waterproof resin are also used.

Styrofoam (foamed polystyrene) is one of the most widely used heat insulation materials. It is a resource-saving material in which 95% of its volume is air and the remaining 2% is resin. It is very light in weight compared to its volume and has water resistance, insulation, soundproofing, Is widely used because it is excellent. However, since the styrofoam is light in weight but has a large volume, it is inconvenient to handle and move, and its durability is so weak that it is easily damaged due to careless handling at the time of construction and is very vulnerable to flammability and ignition, have.

In addition, existing insulation materials including the above-mentioned styrofoam cause condensation in the inside of the insulation due to the difference in temperature and humidity, thereby causing harmful bacteria such as molds to propagate and making the room unsanitary, and the insulation effect is not satisfactory many.

In addition, most of the heat insulation material is completed through a certain process such as foaming, and since the volume of the material is very large, the construction area of some materials is considerably wide. However, in the case where the standard of the construction object is not standardized, There is a problem that it is uneconomical and workability is poor. Since most of the heat insulation materials are bulky, it is common to work with such inconveniences.

In recent years, however, coating type heat insulation materials that are applied to a target object have become popular, and epoxy primer has been applied after primer application, or a composition in which insulation materials are reinforced for existing filler materials However, when these materials are used, there is a problem that a finishing material must be used again in a post-process, and harmful components are eluted.

Accordingly, there is a demand for the development of a finishing material which is excellent in flame retardancy and heat insulation property, does not dissolve harmful components, has excellent strength and is easy to apply.
