摘要
以脲醛树脂(UF)和硅丙乳液(SEA)树脂分别为基料,三聚氰胺磷酸盐(MP)-三聚氰胺(MEL)-季戊四醇(PER)为膨胀阻燃体系,制备膨胀型阻燃涂料。通过极限氧指数、热重分析、锥形量热、扫描电镜对涂料阻燃性能表征分析证明,与SEA相比,UF分解温度较低,残炭量提高了11.53%;与硅丙乳液基三聚氰胺磷酸盐涂料(SEA/MP)木材阻燃涂料相比,脲醛树脂基三聚氰胺磷酸盐涂料(UF/MP/MEL/PER)木材阻燃涂料具有良好的阻燃性能、热稳定性和抑烟性能,残炭量提高了5.05%,总放热量降低了17.0%,总烟气生成量降低了39.3%,在木材表面形成的炭层更加完整。
The melamine phosphate-melamine-pentaerythritol, as intumescent fire retardant, was respectively blended with two different base materials which were used in wood flame retardant coatings, namely, urea formaldehyde resin（UF） and silicone acrylic emulsion resin（SEA）, to prepare the UF/IFR composite and SEA/IFR composite. Through the analysis of limit oxygen index （LOI）, thermogravimetric （TG）, cone calorimeter （CONE） and scanning electron microscopy （SEM）, it is obtained that the decomposition temperature of UF is decreased and the residues of it is increased by 11.53 % around, compared with the SEA. Moreover, the flame retardancy, thermal stability and smoke suppressing of UF/melamine polyphosphate （ MP ）/melamine （ MEL ）/pentaerythritol （ PER ） composite were obviously improved in comparison with SEA/MP/MEL/PER composite. In addition, the residues char of wood flame retardant coatings is increased by 5.05 % around; the total heat release is decreased by 17.0 % ; the production of total flue gas is decreased by 39.3 % and the carbon layer on the surface of wood is more integrated.
