場上單一有機(jī)保溫材料易燃,存在安全隱患。無機(jī)材料保溫效果不理想。研制出高強(qiáng)輕質(zhì),防火保溫隔熱材料擁有廣闊市場空間。本實(shí)驗(yàn)采用水玻璃膠結(jié)經(jīng)硅氣凝膠浸泡后的膨脹珍珠巖顆粒,裝入模具熱壓制板。實(shí)驗(yàn)表明,板材抗壓強(qiáng)度為0.2MPa—0.3MPa,分析硅氣凝膠未能充分浸入膨脹珍珠巖顆粒。憎水性材料,分析經(jīng)硅氣凝膠改性導(dǎo)致板材憎水性能增強(qiáng)。導(dǎo)熱系數(shù)小可達(dá)0.049W·(m·k)-1,分析硅氣凝膠部分浸入顆粒內(nèi)部且充滿板材空隙,水玻璃密封效果較好。

膨脹珍珠巖保溫板是集保溫、隔熱和防水功能于一體的新型外墻保溫板材。珍珠巖保溫板質(zhì)輕且保溫隔熱性能優(yōu)良,防火防塵防潮、不變形改性、不腐爛發(fā)霉、無毒無味憎水性能好(憎水率可達(dá)98%以上),施工安全簡單易行,屋面與墻面粘貼均可以天然礦石為原料,有良好的環(huán)保性。但是珍珠巖在使用過程中會(huì)產(chǎn)生裂紋,產(chǎn)生裂紋

尹太銀生產(chǎn)的乳化瀝青珍珠巖是一種以乳化瀝青為膠結(jié)劑，與膨脹珍珠巖砂混合，在常溫下經(jīng)攪拌加壓成型的新型保溫材料。它具有容重輕、保溫性能好、吸濕率低、冷作業(yè)施工易于保證質(zhì)量等優(yōu)點(diǎn)。它用作屋面保溫層，既可現(xiàn)澆又可預(yù)制。乳化瀝青膨脹珍珠巖主要用于異性設(shè)備、罐體，球體墻壁的保溫和隔音，具有施工方便，易操作。本產(chǎn)品不腐蝕設(shè)備，且無放射性，符合國家環(huán)保要求，是其它傳統(tǒng)保溫產(chǎn)品無法比擬的換代高效節(jié)能新材料。它是以瀝青為粘結(jié)劑的膨脹珍珠巖絕熱保溫板，包括石油瀝青膨脹珍珠巖保溫板和乳化瀝青膨脹珍珠巖保溫板兩種類型。膨脹珍珠巖的密度要求小于120 kg/m3。

以脫硫石膏為膠凝材料,以膨脹珍珠巖為輕質(zhì)骨料,摻加適量的粉煤灰及其他外加劑,經(jīng)澆注成型制備膨脹珍珠巖保溫板。膨脹珍珠巖表面疏松多孔,其應(yīng)用受到了限制。采用VAE乳液包覆膨脹珍珠巖表面的孔,可降低其吸水率;或采用硬脂酸炒制膨脹珍珠巖,覆蓋在其表面和孔洞,使其由親水轉(zhuǎn)變?yōu)樵魉?也可降低其吸水率。通過試驗(yàn),摻加改性后膨脹珍珠巖的保溫材料的防水性能提高,吸水率下降。摻加VAE乳液改性的膨脹珍珠巖的保溫材料的力學(xué)性能和導(dǎo)熱性能有所改善。利用SEM測試手段對(duì)VAE改性的膨脹珍珠巖進(jìn)行微觀結(jié)構(gòu)分析,同時(shí)探討其防水機(jī)理。

The perlite separates the heat preservation board (FSG hatred water heat preservation board) is take the inflated pearlite bulk as an aggregate, joins the water-repellent and the cementing agent carries on the heat insulation waterproofing heat preservation board which working procedures and so on configuration, screening, compression formation, drying make. The FSG hatred water heat preservation board has solved each kind of building roofing heat preservation, the heat insulation and the waterproof function effectively in a body's technical difficult problem, saved the massive constructions and the service fund.product characteristic:The nature is light, and heat preservation heat insulation performance fine fire protection. Dustproof. Moisture-proof, does not distort the modification, not rottenly mildewy, the non-toxic tasteless hatred water performance to be good, hates Shui Lvke to reach above 98% to construct safely easy and feasible, the roofing and the wall surface glue may the natural ore be raw materials, has the good environment-protective.
