- the sheet of the present invention which has excellent fire retardation performance, is installed in the battery module of an electric vehicle, it is possible to secure evacuation time by delaying the spread of fire between electric vehicle battery modules, and by limiting the area where the fire occurs locally, the recovery range when repairing the battery. can be minimized.
- the sheet of the present invention can be molded according to the battery pack design and then installed inside the battery pack, processes such as applying and drying the paint composition can be omitted and has excellent constructability.
- the sheet of the present invention can be inserted and installed between a plurality of battery modules constituting a battery pack.
- flame retardant adhesive can be applied to the sheet surface, or a fixing device can be installed inside the battery pack.
- the paint composition of each example was prepared by adding each component according to Table 1 below.
- the paint composition of each comparative example was prepared by adding each component according to Table 2 below.
- Epoxy resin Bisphenol A epoxy (Kukdo Chemical, YD-128)
- Reactive Diluent 1 Trimethylolpropane triacrylate
- Reactive Diluent 2 Neopentyl glycol diglycidyl ether
- Reactive diluent 3 Neodecanoic acid 2,3-epoxypropyl ester
- Foaming agent 1 Melamine
- Foaming Agent 2 Zinc Borate
- Acid catalyst Ammonium polyphosphate (JLS FLAME RETARDANTS, JLS-APP)
- Thickener 1 Organophilic phyllosilicates (BYK, GARAMITE 1958)
- Thickener 2 Fumed Silica (KCC, D-200)
- Colorant Black epoxy colorant (KCC, YE2408K)
- Fiber 1 Aluminosilicate fiber (UNIFRAX, HS-95C)
- Fiber 2 Magnesium silicate fiber (UNIFRAX, HI-90)
- Fiber 3 Mineral wool (LAPINUS, MS-615)
- Fiber 4 Carbon Fiber (ACECA, 3NA)
- Curing accelerator Tris-2,4,6-dimethylaminomethyl phenol
- the foaming rate was calculated using the following formula.
- the fire resistance test was a fire resistance test in an electric furnace (internal temperature: 950°C), and the thickness was measured with vernier calipers.
- Foaming rate [(Thickness after fire resistance test - Thickness before fire resistance test) / Thickness before fire resistance test]
- a specimen was manufactured by attaching each sheet onto a 140 mm x 140 mm x 3 mm aluminum specimen.
- a K-Type thermocouple was attached to the back of each specimen to measure the back surface temperature, and the fire resistance performance of the paint composition was evaluated according to IMO Res.MSC307(88) (electric furnace: 950°C).
- sheet processability was evaluated by quantifying the degree of sheet deformation and damage when making a sheet with the required film thickness (3 (excellent) for a normal film, severe deformation) and 0 (thirteen) in case of damage.
- the coating compositions of Examples 1-4 according to the present invention showed excellent physical properties in all measurement items.
- the paint compositions of Comparative Examples 1-6 in which the content of melamine or borate was outside the scope of the present invention, showed overall inferior physical properties compared to the paint compositions of the examples.
- the present invention provides a coating composition with excellent heat resistance, weather resistance, and fire propagation delay performance. Additionally, the present invention provides a sheet manufactured from the above coating composition and having excellent heat resistance.
