Abstract

The invention discloses a smoke suppressant type indoor ultrathin fire-resistant paint for a steel structure. The fire-resistant paint is composed of the following components in parts by weight: 20-35 parts of synthetic resin base material, 25-45 parts of fire-resistant aid, 3-10 parts of titanium white, 5-15 parts of smoke suppressant filler, 1-3 parts of aid and 16-28 parts of solvent. Meanwhile, the invention also discloses a preparation process of the smoke suppressant type indoor ultrathin fire-resistant paint for a steel structure. According to the invention, the synthetic resin base material and the smoke suppressant filler are used, so that the prepared paint has very good fire resistance and excellent water resistance and weather resistance; and almost no toxic irritative gas is discharged in case of fire-induced expansion.

Description

technical field [0001] The invention relates to a novel fireproof coating, in particular to a smoke-suppressing indoor ultra-thin steel structure fireproof coating and a preparation process thereof. [0002] technical background [0003] Although the steel structure itself is a non-combustible material, the steel structure has a fatal weakness of poor fire resistance. Under the high temperature of a fire, its mechanical properties such as yield strength, elastic modulus, and load capacity will drop sharply with the increase of temperature. When the heating temperature of the steel structure reaches 600°C, the steel structure basically loses all its strength and stiffness, resulting in excessive deformation and cannot continue to be used. Generally, the temperature of a fire scene reaches 800°C-1000°C. At such a high temperature, the exposed steel structure will quickly undergo plastic deformation and cause local damage, causing the entire steel structure building to lose its ...
