Abstract

The invention discloses a cobalt-molybdenum sulfide composite flame retardant, a fireproof coating and preparation methods of the cobalt-molybdenum sulfide composite flame retardant and the fireproof coating, and belongs to the technical field of fireproof coatings. The cobalt-molybdenum sulfide composite flame retardant comprises Co-MOF and MoS2, the MoS2 is embedded in holes and combined with open positions of Co2+ ions to form a CoMoS phase, and a molybdenum sulfide modified organic framework material synthesized on the basis of the Co-MOF by the flame retardant has a larger specific surface area and a larger catalytic effect, has more active sites, can be used for preparing a high-performance flame retardant, and facilitates the combination with oxygen to form a complete combustion product.

Description

technical field [0001] The invention belongs to the technical field of fireproof coatings, and more specifically relates to a cobalt-molybdenum sulfide composite flame retardant, fireproof coatings and their preparation methods. Background technique [0002] Although steel is non-combustible, it has the characteristics of heat resistance and high temperature resistance, and it is easy to conduct heat. Heating of steel structures can cause harm in the following two aspects: on the one hand, due to the high thermal expansion coefficient of steel, it is easy to cause deformation of the structure or elongation of components at high temperature, and it is easy to cause bending of components when the two sides of the steel are heated unevenly; on the other hand, The mechanical properties of steel, such as: yield stress, elastic modulus, etc., gradually decrease with the increase of temperature. When the critical temperature (540°C) is reached, the steel structure will lose its su...
