膨胀涂料

帮助钢保持冷却

膨胀系统是各种化合物的组合,发生火灾时随着温度升高这些化合物共同反应,形成泡沫碳。该泡沫厚度比最初所涂的涂料厚 10 至 100 倍,并且通过其低导热率隔绝基质材料。特别是对于钢框架结构,这是非常必要的。因为当火灾中温度超过 500°C 时,钢框架结构会失去结构稳定性。此类建筑的例子有机场、购物中心、医院和办公楼。

作为关键原料聚磷酸铵的主要供应商,科莱恩在膨胀涂料原材料、膨胀涂料配方(水基或溶剂基)开发方面有着全面的经验。

所使用的 Exolit® AP 产品是基于聚磷酸铵的白色精细粉末。

It is manufactured from ammonium polyphosphate by micro-encapsulation with melamine resin according to Clariant’s own method. Exolit AP 462 is a fine-particle white powder with very low solubility in water, even at elevated temperatures. It is completely insoluble in organic solvents. The product is non-hygroscopic and non-flammable. Press the button "Print this page" to download the Product Data Sheet. 更多

    • Exolit® AP 740 F

      Exolit AP 740 F is a white free flowing powder. It is a non-halogenated additive flame retardant based on ammonium polyphosphate which develops its effectiveness through phosphorus/nitrogen synergism. Exolit AP 740 F differs in its mode of action from chlorine or bromine containing flame retardants by achieving its effect through intumescence. The flame retarded material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat-insulating effect and reduces further oxygen access.

    • Exolit® AP 742

      Exolit AP 742 is a non-halogenated, additive flame retardant based on ammonium polyphosphate, which develops its effectiveness through a phosphorus/nitrogen synergism. Exolit AP 742 differs in its mode of action from other flame retardant technologies (e.g. chlorine- or bromine-containing flame retardants and minerals) by achieving its effect through intumescence. The flame retarded material foams on exposure to flame. The carbon foam layer so formed protects the polymer by its heat-insulating effect and reduces further oxygen access.

    • Exolit® AP 750

      Exolit AP 750 is a non-halogenated flame retardant based on ammonium polyphosphate as main component, which develops its effectiveness through phosphorus/nitrogen synergism. In contrast to similar competitive material, it shows high processing stability. Exolit AP 750 differs in its mode of action from non phosphorus-based flame retardants (e. g. brominated, chlorinated or mineral FRs like ATH) by achieving its effect through intumescence. Material containing Exolit AP 750 will foam on exposure to flame. The carbon-rich foam layer so formed will protect the polymer and in many cases the substrate below through its heat-insulating effect, reduces further oxygen access and prevents dripping in case of a thermoplastic based formulation. Beyond the primary effects on fire behavior such as reduction of flame propagation rate, rate of heat release, dripping behavior, residual lengths of test specimens after flame tests etc., positive secondary fire effects such as low smoke density, no release of corrosive off-gases, lower formation of toxic smoke gases are of great interest.

    • Exolit® IFR 36

      Exolit IFR 36 is a non-halogenated flame retardant based on ammonium polyphosphate, which develops its effectiveness through phosphorus/nitrogen synergism. Exolit IFR 36 differs in its mode of action from chlorine- or bromine-containing flame retardants by achieving its effect through intumescence. The flame retarded material foams on exposure to flame.
