摘要

The Vac-veova latex coatings was a good type of film-forming material in intumescent fire retardant coatings, it had good properties in high thermal stability, so it was very suitable to serve as the film-forming material of IFR coatings for structural steel to improve its fire resistance. According to the research results, the different ratio between each component had obvious difference for fire prevention effect, in the APP/PER/MEL/EG for IFR coatings, the best ratio of APP/PER/MEL/EG was 5.25:2:2:1.25, and the best content ratio between IFR and Vac-veova latex emulsion was 35/25. According to the chosen component ratio in IFR, its intumescent ratio could reach 22.68%, the fire-resistant time reached 149s. After burnt out, the residual weight reached 47.12% at 75kW/m~2.
