摘　　要：以醋叔乳液(VAc-VeoVa)为成膜物质,聚磷酸铵/季戊四醇/三聚氰胺/可膨胀石墨(APP/PER/MEL/EG)为膨胀阻燃体系(IFR),研究IFR及其与VAc-VeoVa的比例对防火涂料性能的影响。通过模拟大板燃烧法、耐水性能测试、扫描电镜等技术或分析手段对防火涂料进行了测试与表征。正交实验直观分析结果表明,IFR中对防火涂料的影响顺序依次为:APP>EG>PER>MEL,最佳配比为APP∶PER∶MEL∶EG=22∶8∶8∶4.5。当VAc-VeoVa的用量为30%,IFR的用量为40%时,防火涂层的耐水性最佳,防火性能最好。VAc-VeoVa latexes was used as binder and ammonium polyphosphate/pentaerythritol/melamine /expandable graphite（APP/PER/MEL/EG）were used as intumescent flame-retardant system（IFR）,in order to investigate the effects of IFR and its proportion with VAc-VeoVa latexes on the performance of fire-retardant coatings. Technical and ana- lytical methods, such as the simulated big panel combustion method, water-resistant test, scanning electron micrograpb, etc. were used to test or characterize the fire-retardant coatings. The orthogonal direct analysis showed that the effect order of IFR on fire-retardant coatings was APP）EG）PER）MEL,and the optimal ratio was APP ： PER ： MEL ： EG=22 ： 8 ： 8 ： 4. 5. When the weight content of VAc-VeoVa latexes was 30% and the weight content of APP/PER/MEL/EG was 40% ,the results showed that coatings possessed the optimal water-resistant property and the best fire-retardant performance.
