Smoke-suppressing type outdoor flame retardant steel structure fireproof coating

Abstract

The invention provides smoke-suppressing type outdoor flame retardant steel structure fireproof coating and a manufacturing method. The coating comprises an adhesive, powder, aggregate, a flame retardant, a smoke-suppressing agent and a reinforcing material. The powder except cement and the adhesive are powdered and sieved, reinforcing fiber is uniformly dispersed, and all the additives, the powder and the cement are mixed according to a ratio, activated and fully stirred. A thermal insulation property of the coating is achieved by utilization of heat reflection of added hollow microbeads and characteristics of expanded perlite. Smoke-suppressing and flame retardant properties of the coating are achieved by utilization of characteristics of the added flame retardant and the added smoke-suppressing agent. The coating has rigidity of the cement and flexibility of polymer, and coatings of the coating are low in density, good in adhesion property, water proofness and flexibility, high in adhesive force, not liable to be affected with damp, not liable to powder and not liable to shed.

Description

technical field [0001] The invention relates to a fireproof paint, in particular to an outdoor fireproof steel structure fireproof paint with excellent smoke suppression performance. Background technique [0002] Steel structure has the advantages of light weight, easy installation, short construction period, excellent seismic performance, high degree of mechanization in manufacturing and installation, and less pollution. a fatal flaw. Under the action of the high temperature of the flame, the mechanical properties of the steel structure decrease rapidly with the increase of temperature. When the temperature reaches about 550°C, the steel structure will gradually lose its load-bearing capacity. Concrete also has fire resistance problems. Due to the complex and discrete components of its constituent materials, large differences in thermal parameters, and differences in physical and chemical properties of materials, it produces stress deformation, temperature deformation and ...

AI Technical Summary

Problems solved by technology

[0010] 1. Although it has good fireproof performance, the paint can be directly sprayed on the surface of the steel structure, but the surface strength is low, external decoration is required, and the project cost is too high

[0011] 2. The paint binder is a high-molecular polymer. Although the amount is not much, it will burn at high temperature, and will decompose toxic fumes that are harmful to human health when burning.

[0012] 3. Poor construction performance will affect the construction speed and cause material loss

[0013] 4. Poor construction performance will affect the construction speed and cause material loss
