Description

Flame retardant paint composition and method for manufacturing flame retardant paint using same {Fireproof Paint Composition and Manufacturing Method of using pretty for Fireproof Paint}

The present invention relates to a composition for flame retardant paint and a method for preparing a flame retardant paint using the same, and more particularly, a composition in which a mixture of silicate, which is harmless to the human body, is mixed with ion-exchanged water, a water repellent mixture, and an acrylic emulsion mixture at a predetermined ratio. Flame-retardant paint is formed by stirring, heating, cooling and aging at an appropriate temperature to prevent diffusion without harmful gas in the event of fire, and there is no harmful substance with water-soluble inorganic material, acid resistance, alkali resistance, antifouling, insect repellent, pore resistance To provide a composition for flame retardant paints having excellent environmental resistance and increased life span of paints with excellent wear resistance, and a method for producing a flame retardant paint using the same.

In general, the flame retardant treatment is to treat the surface with a material that blocks the occurrence and spread of the fire in the internal and external materials of buildings and underground facilities, to prevent the occurrence and spread of the fire to promote safety.

As in modern times, when a fire occurs due to the increase of high-rise buildings, the expansion of underground facilities such as subways, and the congestion of houses, it is easy to spread to a large size, and it is difficult to extinguish the fire due to the difficulty of accessing the place where the fire occurs. Difficult to evacuate, there was a problem that a lot of human injury occurs.

Therefore, the fire control method is to designate the object of flame retardant to prevent the occurrence and spread of fire, so that various installation membranes, interior items, carpets, etc., which are anti-flame pretreatment products, are flame-retarded during manufacturing or production, It is required to manufacture or produce flame retardant materials.

In addition, high-rise buildings subject to post-treatment (meaning more than 11 stories above ground level), massage parlors, gymnasiums, special baths, viewing halls and sports facilities (except swimming pools) , General accommodation, tourist accommodation, general hospital (with hospitalization room), broadcasting station, cinema, exhibition hall, multi-use business, youth facility (accommodation with accommodation), homeless person, general restaurant As the floor area of the workplace is 100m2 and the basement floor is 66m2 or more, it is prescribed in Article 11 of the Enforcement Decree of the Fire Services Act to treat the surface where it is difficult to produce the main material with flame retardant like fire retardant paint.

As mentioned above, the facilities prescribed by the law are mandatory to use flame retardant products such as flame retardant paints to minimize the damage of fire.

As such, the flame retardant paint for delaying the initial occurrence of the fire of the prior art is disclosed in Korean Patent No. 10-0495159, looking at it as follows.

As described above, the composition for flame retardant paints of the prior art is a composition for flame retardant paints prepared by using a chlorinated rubber resin as a main resin and optionally using a phenolic resin and optionally a vinyl chloride / isobutyl ether-based vinyl copolymer as an auxiliary resin. If the coating film is formed by coating it with a dry coating thickness of about 80-100 microns, it is possible to delay initial ignition by foaming the coating film to form a heat insulation layer in case of fire. Not only does this show excellent flame retardant performance, but it also enables the aesthetic advantages of combustible materials such as wood.

However, the flame retardant paint composition of the prior art is a material that is highly flame retardant to prevent the occurrence and spread of fire, using a vinyl chloride-based resin material similar to the general paint and excellent solubility, and a phenolic resin and optionally chloride Formed from vinyl / isobutyl ether-based vinyl copolymer, it is made of petrochemical products and made of paint as the main raw material, and painted on the interior and exterior side, which suppresses flame generation or diffusion but generates toxic gas in the heated paint part.
