Problems solved by technology

At present, fire prevention measures for steel structures can be divided into several categories: (1) laying bricks or spraying a layer of concrete mortar on the surface of the steel structure; (2) wrapping inorganic fiber cloth and inorganic fiber felt on the surface of the steel structure; Fill the hollow steel column with treated liquid and water; (4) Paste non-combustible plates on steel structure columns, beams, floor slabs and other structures; the above method is complex in construction, high in cost, and will affect the appearance

Abstract

The invention discloses an indoor ultrathin steel-structure fireproof coating. The indoor ultrathin steel-structure fireproof coating comprises the following raw materials in parts by weight: 30-40 parts of amino resin, 10-20 parts of solvent oil, 20-30 parts of ammonium polyphosphate, 2-10 parts of mica powder, 5-12 parts of melamine, 5-12 parts of pentaerythritol, 0.5-1.5 parts of bentonite and 2-4 parts of chlorinated paraffin. Relevant indexes of the indoor ultrathin steel-structure fireproof coating reach national standards, and no toxic gas is released in the construction process, so that the coating is safe and environmentally friendly and can be applied to various steel-structure buildings; the surface drying time and the duration of fire resistance of the coating are superior to national standards, the effect is obvious, and the coating has high market value.

Description

Technical field [0001] The invention belongs to the technical field of fireproof coatings, and specifically relates to an indoor ultra-thin steel structure fireproof coating and a preparation method thereof. Background technique [0002] Steel structure is a common structural form of modern buildings. It has many advantages such as high strength, strong load, light weight, and small size. With the rapid development of China's economic construction, steel structure buildings appear in large numbers in public buildings, commercial buildings and other high-rise buildings. And in industrial plants, although the steel structure has many advantages, it also has the problem of poor fire resistance. Especially when the temperature reaches 400~600℃, the strength of the steel structure decreases linearly. When the temperature reaches 600℃ or higher, the steel structure The structure almost lost its carrying capacity. Therefore, it is very important to take effective protection measures fo...
