Embodiment 1～6

[0052] According to the chemical composition in Table 1 below, a mixture containing perlite, cement, gypsum stucco, silica, paper pulp and other additives was poured into an appropriate amount of water to make a slurry. The surface of an H-shaped steel (300×300×10×20 mmt, L2000 mm) as a sample was coated with this slurry. Keep the coating agent at a distance of 30 cm from the coated side at 2 m 3 / hr spray volume vertical spraying. Continue the spraying operation until the coating agent is detached on the corresponding building position, and measure the thickness of one spray coating. The thickness gage is then pressed vertically into the corresponding central building location of each sample to be measured to measure the thickness of each sample twice. More specifically, when the thickness-measuring needle reaches the corresponding building position, a sufficient force is applied to maintain the planar surface of the coating agent, followed by moving the slide. After separ...

Embodiment 7

[0061] With the same chemical composition as in Example 1, a mixture containing pearlite, cement, gypsum stucco, silica, paper pulp and other additives was poured into an appropriate amount of water to make a slurry. For several groups of samples, Barmlite (thickness: 10 mm, size: 1.2 m x 1.2 m) and foamed styrene foam (thickness: 50 mm, size: 1.2 m x 1.2 m) were used as raw materials, and the coating composition used on these materials.

[0062] The coating composition was sprayed onto the Barmlite to a thickness of 10 mm (sample 1), 20 mm (sample 2), 30 mm (sample 3) and 50 mm (sample 4). The coating composition was sprayed onto foam-styrene foam at a thickness of 10 mm (sample 5) and 20 mm (sample 6), respectively. The prepared samples have a density of 320-370kg / m 3 In the range.

[0063] These samples 1 to 6 were transferred into a soundproof room, and for the measurement of sound absorbing ability, each unit sample was collected. In order to meet the size of the samp...

Abstract

The invention obtains a coating compsn. which exhibits excellent fire resistance and sound absorbing performance in the min. coating thickness by incorporating specified proportions of a lightweight aggregate, a binder, a heat absorbing material, an expanding material and carbonaceous sound absorbing fibers. The coating compsn. contains 25-60 wt.% lightweight aggregate, 20-60 wt.% binder such as Portland cement, <=50 wt.% heat absorbing material, 5-30 wt.% expanding material such as silica and 2-20 wt.% carbonaceous sound absorbing fibers such as surfactant, thickener, strength enhancer, retarder and antibacterial agent such as pentachlorolaurate.

Description

technical field [0001] The present invention relates to a coating composition for fire protection and acoustic applications, and in particular to a coating composition with excellent overall properties, wherein the coating composition of the present invention can prevent steel skeleton structures from burning at extremely high temperatures The reduction in strength and the deterioration of internal force, and the better sound insulation performance by spraying on the surface of the steel skeleton structure including the wall or ceiling of the building. Background technique [0002] With rapid urbanization resulting in a massive increase in densely populated areas, large areas of high-rise buildings are being constructed in an effort to accommodate large numbers of people in small areas. In order to adapt to this situation, a large number of steel skeleton structures are used. [0003] However, it is very dangerous to directly use the steel frame structure in a large-scale h...
