Technical Field

Steel structures, which are required to withstand the effects of the various possible natural and man-made environments, are engineering structures and structures with sufficient reliability and good socioeconomic performance, and have become one of the main types of building structures. The steel has the advantages of high strength, light dead weight, good rigidity, strong deformability, good isotropy and the like, so the steel structure is widely applied to various engineering buildings. When the surface temperature of the steel structure is below 200 ℃, the strength change is small, but when the surface temperature of the steel structure reaches 300-400 ℃, the strength and the elastic modulus are obviously reduced, and when the surface temperature of the steel structure reaches 600 ℃, the strength is basically 0, so that when the steel structure is used, the steel structure material needs to be subjected to fire-proof treatment to improve the high-temperature-resistant and fire-proof performance. In order to improve the fireproof performance of a steel structure, at present, fireproof paint is usually sprayed on the surface of the steel structure, and the existing fireproof paint usually needs to be sprayed for multiple times to reach more than 38mm to play a fireproof role, which generally needs workers to spray the surface of the steel structure for multiple times, and the next spraying needs to be carried out after waiting for 4-8 hours after each spraying, so that higher labor cost and time cost are caused, and the labor efficiency is lower. In addition, the existing fireproof coating is easy to crack, hollowing and the like.

A flame retardant composite for construction according to any of claims 1 to 3 wherein: the filler comprises one or a mixture of more of calcined kaolin, talcum powder, mica powder, asbestos powder, nano-silica and aluminum silicate, and the gypsum retarder is selected from one or a mixture of more of sodium citrate, tartaric acid, potassium tartrate, acrylic acid, sodium acrylate and borax.
9. A flame retardant composite for construction according to any of claims 1 to 3 wherein: the filler is modified kaolin, and the preparation method of the modified kaolin comprises the following steps: firstly, mixing the following components in parts by weight of 1: 5, adding the water and kaolin into a ball mill for ball milling treatment for 1.5h to obtain slurry, then putting the slurry into a centrifuge for centrifugal precipitation to obtain solid particles, then adding the solid particles into a high-speed stirrer, dropwise adding a silane coupling agent while stirring, stirring for 40min after the dropwise adding is finished, and finally washing and drying to obtain the modified kaolin.
10. The method of constructing a fire retardant composite for construction according to the above claims, characterized by comprising at least the following steps: (1) uniformly mixing the materials in the component A, mixing water and the component A according to the mass ratio of (1.1-1.45) to 1, and uniformly stirring to obtain slurry; (2) mixing water and the component B according to the mass ratio of (1.4-1.6) to 1 to obtain a curing agent solution; (3) respectively adding the slurry and the curing agent solution into a double-group spraying machine so as to uniformly mix the curing agent solution and the slurry at a gun mouth; the mass ratio of the slurry to the curing agent solution is 1 (0.02-0.33); (4) and spraying a layer of the flame-retardant composite material for the structure on the base material, wherein the thickness of one-time spraying is 40-50 mm.
