【摘要】：近年來建筑火災(zāi)的頻繁發(fā)生,與建筑墻體保溫層的有機(jī)材料不無關(guān)系。因此,高效無機(jī)保溫隔熱材料迎來了前所未有的發(fā)展機(jī)遇。通過對材質(zhì)、技術(shù)及資源狀況等方面的綜合分析,本論文開展了以膨脹珍珠巖為絕熱材料保溫隔熱板材的研發(fā)及其產(chǎn)業(yè)化以及創(chuàng)新型無機(jī)保溫隔熱材料的探索。 本文的研究主要圍繞膨脹珍珠巖基水玻璃粘結(jié)劑體系無機(jī)保溫隔熱板材的優(yōu)化、膨脹珍珠巖基水泥粘結(jié)劑體系無機(jī)保溫隔熱板材的研發(fā)及其產(chǎn)業(yè)化和創(chuàng)新型無機(jī)保溫材料—低溫泡沫玻璃的初步探索三個方面展開。通過對水玻璃粘結(jié)劑的改性、膨脹珍珠巖骨料的不同種類、級配、憎水性的改性等方面的研究,與現(xiàn)有的水玻璃膨脹珍珠巖體系無機(jī)保溫隔熱板材相比,優(yōu)化后板材的性能得到了很大程度上的改善：力學(xué)強(qiáng)度提高了30%,導(dǎo)熱系數(shù)降低了20%,軟化系數(shù)由40%提高到了70%以上；水泥膨脹珍珠巖體系無機(jī)保溫隔熱板材的研發(fā),主要從板材成型工藝、原料配方及養(yǎng)護(hù)制度對板材性能的影響等方面著手,研制出了一種容重約為180kg/m3,抗壓強(qiáng)度高于0.8MPa,導(dǎo)熱系數(shù)低于0.06W/(m-K),養(yǎng)護(hù)時間少于10h的高性能無機(jī)板材,并完成了其相應(yīng)的產(chǎn)業(yè)化中試；通過膠體化學(xué)工藝得到Na2O-B2O3-SiO2系高粘度溶膠,然后將得到的溶膠進(jìn)行低溫干燥及熱處理發(fā)泡從而獲得一種新型非晶態(tài)、多孔水合玻璃材料,且這種材料有望成為下一代廣泛應(yīng)用的新型無機(jī)保溫隔熱材料。
[Abstract]:The frequent occurrence of building fire in recent years is related to the organic materials of building wall insulation layer. Therefore, high-efficiency inorganic thermal insulation materials ushered in unprecedented opportunities for development. Based on the comprehensive analysis of material, technology and resource status, the research and development of thermal insulation board with expanded perlite as insulation material and its industrialization as well as the exploration of innovative inorganic thermal insulation material are carried out in this paper. This paper focuses on the optimization of expanded perlite based water glass binder system inorganic thermal insulation plate. The development and industrialization of inorganic thermal insulation board of expanded perlite based cement binder system and the preliminary exploration of innovative inorganic thermal insulation material-low temperature foam glass were carried out. Through the modification of sodium silicate binder, different kinds of expanded perlite aggregate, gradation, hydrophobicity modification and so on, compared with the existing inorganic thermal insulation plate of water glass expanded perlite system, The properties of the optimized plates have been greatly improved: the mechanical strength has been increased by 30 percent, the thermal conductivity has been reduced by 20 percent, the softening coefficient has been increased from 40 percent to more than 70 percent, and the development of inorganic thermal insulation plates for cement expansion perlite systems, A kind of high performance inorganic plate with a bulk density of about 180kg / m ~ 3, compressive strength of more than 0.8MPa, thermal conductivity lower than 0.06W/ (m-K) and curing time of less than 10h was developed from the aspects of forming process, formula of raw materials and curing system, etc. The high viscosity sol of Na2O-B2O3-SiO2 system was obtained by colloidal chemical process, and then the sol was dried at low temperature and foamed by heat treatment to obtain a new amorphous, porous hydrated glass material. And this material is expected to be a new type of inorganic insulation material widely used in the next generation.
