【摘要】：為解決目前市場上A級建筑保溫材料的嚴重短缺,結(jié)合國內(nèi)豐富的煤瀝青資源,并拓展泡沫炭的應用范圍,本文采用自升壓-自發(fā)泡法制得泡沫炭。具體選用國內(nèi)來源豐富、價格低廉的煤瀝青為原料,先將其調(diào)制成高軟化點瀝青,再以之為原料采用自升壓-自發(fā)泡法制得泡沫炭,并對泡沫炭的工程放大效應進行了初步探索。本文的創(chuàng)新之處在于：1)選擇以煤瀝青為原料,通過抽真空改性調(diào)控其族組成,實現(xiàn)在近常壓下發(fā)泡；2)將煤瀝青最終轉(zhuǎn)化成泡沫炭并用于節(jié)能建筑領(lǐng)域,不僅拓展了泡沫炭的應用范圍,而且可以有效解決國內(nèi)大量煤瀝青的大規(guī)模使用難題。在煤瀝青基泡沫炭的結(jié)構(gòu)控制及其放大研究過程中,得到如下主要結(jié)果或結(jié)論： 1)對高軟化點瀝青(軟化點為241℃)進行抽真空改性,抽真空條件為350-420℃/0.5-3h,當族組成分布為HS-1.6%、HI-TS-3.77%、TI-PS-9.42%、PI-QS-19.45%、 QI-65.76%時,可以制得孔結(jié)構(gòu)均一的泡沫炭。 2)經(jīng)上述抽真空改性的高軟化點瀝青,在1.5MPa/500℃發(fā)泡條件下,可以制得孔徑為100～200μm、體積密度0.501g/cm3、壓縮強度3.50MPa的泡沫炭。 3)經(jīng)上述抽真空改性的高軟化點瀝青,調(diào)整發(fā)泡條件后可以制備出Φ45×100mm、 Φ200×200mm的大尺寸泡沫炭。 4)根據(jù)GB/T14402-2007和GB/T5464-2010,制備的泡沫炭滿足國家A級建筑材料燃燒性能的要求。導熱系數(shù)為0.0798W/(m.K)。
[Abstract]:In order to solve the serious shortage of A grade building insulation material in the market at present, combined with the abundant coal and asphalt resources in China and expanding the application range of foamed carbon, this paper adopts the method of self-boosting and self-foaming to obtain foamed carbon.The coal pitch, which is rich in domestic sources and low in price, is selected as raw material. It is first modulated into bitumen with high softening point and then used as raw material to obtain foamed carbon by self-boosting and self-foaming process.The engineering amplification effect of foamed carbon was preliminarily explored.The innovation of this paper is that: 1) choose coal pitch as raw material, through vacuum modification to adjust its family composition, and realize foaming at near atmospheric pressure) to convert coal pitch into foamed charcoal and be used in energy-saving building field.It not only expands the application range of foamed carbon, but also can effectively solve the problem of large scale use of coal tar pitch in China.In the process of structure control and magnification of coal bitumen based foamed carbon, the main results or conclusions are obtained as follows:1) vacuum modification of asphalt with high softening point (softening point 241 鈩，
