摘要
为解决丙烯酸树脂在使用过程中存在阻燃性能低的问题,通过超声和机械搅拌相结合的方法在丙烯酸树脂乳液中加入由聚磷酸铵(APP)、季戊四醇(PER)和三聚氰胺(MEL)以不同配比复合而成的膨胀型阻燃剂(IFR),制得阻燃丙烯酸树脂涂料(PA-IFR).利用红外光谱仪、X射线衍射仪、铅笔硬度计和极限氧指数仪对 PA-IFR 的化学结构、透光率、硬度以及阻燃性能进行测试.结果表明:当膨胀型阻燃剂的质量分数为 30%,APP/PER/MEL 的配方比为 2∶1∶1时,PA-IFR 的硬度达到 5H,极限氧指数LOI值达 32.6%,属于难燃材料.
Abstract
To solve the problems of low flame retardant performance in the use of acrylic resin,a flame-retardant acrylic resin coating PA-IFR was prepared by adding intumescent flame retardants(IFR)composed of ammonium polyphosphate(APP),pentaerythritol(PER)and melamine(MEL)to the acrylic resin emulsion by combining ultrasonic and mechanical stirring.The chemical structure,transmittance,hardness and flame retardant properties of PA-IFR were tested by infrared spectrometer,X-ray diffractometer,pencil hardness tester and limiting oxygen index meter.The results show that the hardness of the PA-IFR reaches 5 H and the limiting oxygen index(LOI)value reaches 32.6%when the mass fraction of the IFR is 30%and the formula ratio of APP/PER/MEL is 2∶1∶1.The acrylic resin coating prepared in this study is a flame retardant material.
