Description

Nonflammable Fire-resistant Coating Composition, Kit for Preparing the Same, and Fire-resistant Filling Material

The present invention relates to various constructions such as steel, wood, plywood, paper, aluminum sheet (aluminum foil), fabric sheet, non-woven sheet, Styrofoam, urethane foam, PE foam, etc. It relates to a fire resistant paint composition for imparting incombustibility or flame retardancy by applying to materials or applying to the inner or outer walls of buildings. In addition, the present invention relates to a fireproof filler capable of blocking a flame or toxic gas by filling the space of the wall or floor surface through which the pipe passes.

A non-flammable coating composition for forming a non-flammable or flame-retardant coating film by applying it to the inner or outer wall of a building or applying it to various building materials has been developed by various methods.

As one method for preparing the non-combustible coating composition, there is a method of using expandable graphite.

Expanded graphite is dried by permeating acidic compounds between layers of graphite by chemically treating natural flake graphite with an acidic material. It expands 200 to 300 times when heated to 150° C. or higher, and has a particle size of 60 to 300 mesh. Since expanded graphite itself is non-combustible, it is variously applied to non-flammable or flame-retardant products.

Korean Patent No. 0982176 discloses a non-flammable composition comprising a phosphorus-based flame retardant containing a carboxylic acid derivative, a metal oxide, and expanded graphite, wherein the metal oxide is sodium oxide, magnesium oxide, calcium oxide, aluminum oxide, barium oxide and/or zinc oxide.

Korean Patent No. 1601708 discloses a method for producing a non-combustible coating film by immersing expanded graphite by heating expanded graphite to 200 ~ 1,000 ° C. in a coating agent, and grinding the expanded graphite immersed in the coating agent in that state.

Korean Patent No. 1647070 describes thermal expansion that is installed in the space between the inner circumferential surface of a through-hole formed to penetrate through the building structure and the pipe passing through the through-hole, and expands by heat in case of fire to shield the space between the inner circumferential surface of the through-hole and the pipe Liquid A containing isocyanate as a sexual filler; and polyol, expandable graphite, and a filler prepared by mixing liquid B containing caramel sugar phosphate or caramel sugar silica.

The present inventor adheres a glass fiber fabric to the surface of a substrate with a composition mixed with water glass and expanded graphite, and applies a gelling agent composition for gelling by bonding with water glass to the adhered glass fiber fabric to form a non-combustible coating layer A characteristic architectural panel was developed and filed as Patent Application No. 2018-20690 (filed on February 21, 2018).

Expanded graphite is an important component of a coating composition for forming a non-flammable or flame-retardant coating film because it is non-combustible, but there is a problem of scattering when the coating film is burned due to a fire. Because expanded graphite expands 200 to 300 times when heated to 150° C. or higher, if the expanded graphite does not scatter and forms a fixed graphite layer, the graphite layer will produce flame retardant, heat-shielding, and heat-insulating effects, and further combustion will not proceed. it may not be However, if the expanded graphite scatters, flame retardancy, heat shielding, and thermal insulation effects cannot be expected, and combustion proceeds and the fire is amplified.

Another problem of the non-combustible coating composition is that the thickness of the coating film formed on the substrate must be thin. In the conventional non-flammable coating composition, the thickness of the coating film is 3 mm or more and about 20 mm, but in some cases it exceeds 100 mm. As such, when the thickness of the coating film is increased, a detachment phenomenon occurs in which the coating film is separated from the substrate by the load of the coating film itself over time. In particular, when a coating film is formed on the ceiling rather than the wall surface, the detachment phenomenon is more serious. However, when the thickness of the coating film is thin, a problem of poor incombustibility occurs. Due to these conflicting reasons, the development of a coating composition having a thin coating film and excellent incombustibility has not yet been successful.

The present inventors found that, when the non-combustible coating film is burned, the expanded graphite does not scatter and expands to form a fixed graphite layer, so that combustion does not proceed further, and the non-combustible coating composition containing the expanded graphite of the present invention has excellent incombustibility even when the coating film is formed thin. was developed and filed as Patent Application No. 2020-72283 (applied on June 15, 2020).

The present inventors have found that the heat insulation performance and scattering of expanded graphite are more improved than the coating composition of Patent Application No. 2020-72283, and the expanded graphite foam layer foamed at a high temperature of 1,000 to 1,200 ° C. does not detach for 3 hours or more. It has come to develop a paint composition and a fire resistant filler using the same.

It is an object of the present invention to form a new non-combustible coating composition capable of forming a fixed graphite layer by expanding without scattering expanded graphite when a non-combustible coating film formed by coating on one or both sides of various building materials, including the outer or inner wall of a building, is burned is to provide

The binder resin and sugar dissolved in water serve as a binder for bonding the expanded graphite particles in the applied non-combustible coating film, and an adhesive for bonding the coating composition to the substrate.

The silane composition is a composition in which 100 parts by weight of a silane compound is mixed with 0.1 to 2.0 parts by weight of acetic acid, hydrochloric acid or sulfuric acid. The silane compound to which a trace amount of acid is added has good storage stability because it does not change or gel even after one year or more.

The silane compound acts as a gelling agent and an adhesive in the applied non-combustible coating film, and forms a graphite layer adhered to the substrate without scattering the expanded graphite by combining with the expanded graphite at a high temperature of 900° C. or higher.

The fire resistant paint composition of the present invention contains 30 to 120 parts by weight of sugar per 100 parts by weight of the aqueous binder resin solution. Sugar firmly bonds the expanded graphite together with the silane compound to form a graphite layer that is adhered to the substrate without scattering, even in a fire of 900°C or higher. Because expanded graphite does not burn even at a temperature of 2,000℃ or higher, it has excellent insulation and heat dissipation effects.

The non-flammable fire resistant paint composition of the present invention, which includes an aqueous binder resin solution, a silane composition, expanded graphite, and sugar, is gelled within a few hours, or at most within 1 to 2 hours due to the silane compound. This is because the silane compound serves as a gelling agent in the coating composition. Therefore, it must be applied before gelation.

Since the fire resistant paint composition of the present invention gels within a few hours, the composition itself cannot be distributed. Therefore, in order to prepare the coating composition of the present invention, it should be provided as a composition kit. The composition kit for preparing the coating composition of the present invention consists of a mixture (I) in which sugar and expanded graphite are mixed in an aqueous binder resin solution, and a mixture (II) in which a trace amount of acid is added to a silane compound.

The mixture (I) is a mixture of 30 to 120 parts by weight of sugar and 20 to 100 parts by weight of expanded graphite in 100 parts by weight of the binder resin aqueous solution. The mixture (II) is a mixture in which 0.1 to 2.0 parts by weight of an acid is mixed with 100 parts by weight of the silane compound.

The fire resistant paint composition of the present invention is prepared by mixing the mixture (I) and the mixture (II). The mixed paint composition contains 30 to 120 parts by weight of the silane compound, 20 to 100 parts by weight of expanded graphite, and 30 to 120 parts by weight of sugar, based on 100 parts by weight of the binder resin aqueous solution, so that mixture (I) and mixture (II) ) is mixed. The mixture (I) and mixture (II) are stirred for 30 minutes to 1 hour to prepare a fire resistant paint composition of the present invention.

Water may be further added to the coating composition to adjust the viscosity, and the amount of added water is preferably 1 to 40 parts by weight per 100 parts by weight of the binder resin aqueous solution.

The silane compound is hydrolyzed by water in the aqueous solution, the binder resin and sugar are dissolved in the water, and the expanded graphite particles are homogeneously dispersed in the aqueous solution. Binder resin, silane compound, sugar, and expanded graphite form a film that is firmly combined to prevent the graphite from scattering in case of fire.

If cerakwool, mineral wool, and/or starch are added, they are added to the mixture (I). These may be added in an amount of 1 to 10 parts by weight per 100 parts by weight of the aqueous binder resin solution. Polyols added to improve dispersibility of ceramic wool, mineral wool, and/or starch are also added to the mixture (I). The polyol may be added in an amount of 1 to 80 parts by weight per 100 parts by weight of the aqueous binder resin solution.

The fire resistant paint composition of the present invention is applied 1 to 3 times to various building materials including heat insulators or to the inner and outer wall surfaces of buildings to form a 0.1 to 2.0 mm thick coating film. Various building materials such as iron, wood, plywood, paper, aluminum sheet (aluminum foil), fabric sheet, non-woven sheet, Styrofoam, urethane foam, PE foam, etc. may be applied as a substrate on which the coating film is formed. It is also possible to form a coating film imparting incombustibility or flame retardancy by applying it to the inner or outer walls of a building. The expanded graphite contained in the coating film forms a graphite layer that is adhered to the substrate without scattering during or after combustion by chemical bonding with the binder resin, the silane compound, and sugar, thereby maximizing flame retardancy, heat shielding, and heat insulation effects.

Since a coating film having a thickness of 0.1 to 2.0 mm is formed by applying 1 to 3 times to a substrate, it is possible to prevent detachment of the coating film due to its own load, and to provide a non-flammable coating composition having excellent incombustibility even when the coating film is formed thin.
