【摘要】：利用液態(tài)高爐渣直接氣淬纖維化制備高爐渣纖維，加入合理的粘結(jié)劑和添加劑，制備出高爐渣纖維保溫板，可以有效的解決高爐渣處理過程中產(chǎn)生的環(huán)境問題和資源浪費的問題，同時制備出的保溫板應(yīng)用于建筑保溫，可以提高市場上無機保溫材料的市場份額。 利用高爐渣纖維為原料，通過采用不同粘結(jié)劑和添加劑制備出高爐渣纖維保溫板，研究粘結(jié)劑種類、成型壓力、溫度等因素對保溫板的吸水性、憎水性、抗壓強度、抗折強度和抗拉強度等性能的影響規(guī)律，為實際生產(chǎn)保溫板提供了理論依據(jù)。 高爐渣纖維表面平整光滑，，平均直徑為6.4μm，纖維渣球含量為3.2%，纖維本身不燃燒，是一種保溫性能良好的絕熱材料。分別采用水玻璃和羧甲基纖維素納復(fù)合摻加作為粘結(jié)劑以及采用水玻璃和白乳膠復(fù)合摻加作為粘結(jié)劑制備出的高爐渣纖維板相比較，后者的性能更加優(yōu)越。高爐渣纖維板的吸水性和憎水性受到粘結(jié)劑的性能和添加量、成型壓力的影響，最佳憎水率為99.2%，短期吸水量最優(yōu)達到0.79kg/m~2。 高爐渣纖維保溫板在建筑施工中可以通過外墻外保溫和夾心保溫技術(shù)來實現(xiàn)，保溫板制備中加入了合理的粘結(jié)劑和添加劑，優(yōu)化了保溫性能的要求，因此應(yīng)用在建筑施工中可以很好的改善建筑的環(huán)境，起到保溫的作用。
[Abstract]:Blast furnace slag fiber was prepared by direct gas quenching of liquid blast furnace slag, and reasonable binder and additive were added to prepare blast furnace slag fiber insulation plate. It can effectively solve the environmental problems and waste of resources in the process of blast furnace slag treatment. At the same time, the prepared insulation board can be used in building insulation, which can increase the market share of inorganic insulation materials in the market. Blast furnace slag fiber insulation board was prepared by using blast furnace slag fiber as raw material by using different binders and additives. The water absorption, hydrophobicity and compressive strength of blast furnace slag fiber insulation board were studied by the factors of binder type, molding pressure and temperature, etc. The influence rules of flexural strength and tensile strength provide a theoretical basis for the practical production of insulation plate. The surface of blast furnace slag fiber is smooth, the average diameter is 6.4 渭 m, the content of fiber slag ball is 3.2%, the fiber itself does not burn, it is a kind of insulation material with good thermal insulation performance. Compared with the blast furnace slag fiberboard prepared by using water glass and carboxymethyl cellulose sodium as binder and water glass and white latex as binder respectively, the latter has better performance. The water absorption and hydrophobicity of blast furnace slag fibreboard are affected by the properties and addition of binder and molding pressure. The optimum hydrophobic rate is 99.2% and the short-term water absorption is 0.79 kg 路kg ~ (- 1) 路m ~ (- 1) 路h ~ (- 1). Blast furnace slag fiber insulation board can be realized by external wall insulation and sandwich insulation technology in building construction. Reasonable binder and additive are added in the preparation of blast furnace slag insulation board, and the requirements of heat preservation performance are optimized. Therefore, the application in building construction can improve the building environment, play the role of insulation.
