【摘要】 膨胀型饰面防火涂料是一种既有装饰功能又有防火阻燃功能的功能性涂料。涂料在常温下呈普通涂膜,对涂覆基材起装饰的作用,在火焰或高温下发生膨胀,形成体积比原来大几十倍甚至几百倍的海绵状或蜂窝状泡沫炭化层,由于炭化层质地疏松,传热率低,能封闭保护基材,起到很好的阻燃作用,阻止火灾的发生和蔓延,为火灾的救助赢得宝贵的时间。近年来,由于建筑装饰材料的大量采用,火灾呈上升趋势,给国家和个人造成了极大的经济损失,对质量好,经济适用,性价比高的膨胀型饰面防火涂料需求日益增加。但目前饰面防火涂料还存在许多问题,如涂料有机挥发份含量较高,价格较高,阻燃性能有待提高,涂料耐水性能差,贮存不稳定等等。研究经济实用和高性能的防火涂料具有重要意义。本论文的研究工作主要针对膨胀型饰面防火涂料的防火性能的提高和成本的降低等问题展开。1、制备经济实用的白乳胶饰面防火涂料首先,研究了乳液和膨胀阻燃剂APP/PE/MEL对涂料阻燃性能的影响。乳液对防火涂料的阻燃性能起到重要作用,不同的乳液对应不同的防火体系,乳液与阻燃体系协同作用,在白乳胶防火涂料APP-MEL-PE膨胀体系中,三者的最佳配比为10:4:7。然后针对此涂料耐水性能较差和贮存不稳定,通过对体系pH值、粘度和细更多还原

【Abstract】 The expandable ostentatious fireproof coating possesses both decorative function and flame-retardant function.The fireproof coating presents a same appearance with common coating at room temperature, and can be used as decorative material. However, at high temperature caused by burning and fire, the fireproof coating would form the char layer like foam and sponge, and the volume could be expanded tens or even hundreds of times. Due to the loose character and lower heat conductivity, the char layer could protect the substrate materials from fire burning, and prevent fire occurrence or overspread, so that more time could be gotten to put out the fire.In current years, as the large-scale application of the flammable structural or decorative materials, the fearful fire emergency happened frequently to lead huge economical and property loss. The demand of high performance fireproof coatings with lower price and more ornament was sharply increased. However, there are lots of disadvantages in the fireproof coatings, such as high organic fugitive constituents, higher price, lower flame retardancy, poor water-proof performance, and instability in storage. So it is necessary to study low-cost and high performance fireproof coatings.In this thesis, the research works are focused on the preparation of expandable ostentatious fireproof coating with excellent flame retardancy by means of a convenient and low-cost technologic process.更多还原
