技术领域
本发明涉及建筑工程技术领域,尤其涉及一种高防水性的优质泡沫混凝土预制楼板。
背景技术
众所周知,泡沫混凝土是近年来在我国建筑工程中应用越来越广泛的一种新型建筑节能材料,它具有轻质、保温、隔音、减震等多种优点。
目前,传统泡沫混凝土板预制楼板,吸水率高(即其结构层材料含水率过高)、防潮性能较差,容易造成楼板缝开裂,严重影响泡沫混凝土板预制楼板的产品质量。
综上所述,如何克服现有技术中的传统泡沫混凝土板预制楼板防水性能差的技术缺陷,是本领域技术人员亟待解决的技术问题。

所述有机高分子乳液按体积百分比计固含量≥30%;
所述极性有机小分子乳液为硅烷乳液或极性硅烷衍生物乳液;
所述润湿剂为磺化油、皂基或拉开粉BX;
所述防水卷材层包括聚乙烯丙纶高分子复合阻燃防水卷材;所述防水卷材层的化学成分主要由62.5~70.4%的线性低密度聚乙烯树脂,0.5~1.5%的光屏蔽剂,0.5~1.5%的抗氧剂,0.1~0.5%的分散剂,0.5~1.0的助粘剂,28~33%的阻燃母料组成,单位为重量百分数;阻燃母料的成分主要由聚烯烙树脂80~82%、聚乙烯蜡1.5~2.5%、耦联剂14~16%、白油0.8~1.2%,硬脂酸锌0.8~1.2%组成。
优选的,作为一种可实施方案;所述单组份橡胶防水涂料层由热塑性弹性体苯乙烯-丁二烯-苯乙烯SBS、特种橡胶和活性助剂复合而成,构成一种单组份溶剂挥发型涂料。
优选的,作为一种可实施方案;所述复合粘贴共混卷材层由氯化聚乙烯、橡胶混合而成。
优选的,作为一种可实施方案;所述单组份橡胶防水涂料层的厚度为2mm~5mm。
优选的,作为一种可实施方案;所述复合粘贴共混卷材层的厚度为5.0mm~6mm,直接用前述单组份橡胶防水涂料层的单组份溶剂挥发型涂料粘贴。
优选的,作为一种可实施方案;所述保护层具体为由钢筋细石混凝土构成的保护层。
优选的,作为一种可实施方案;所述第一防水层的表面还涂覆有防水涂料。
优选的,作为一种可实施方案;所述防水涂料具体为氟碳涂料。
优选的,作为一种可实施方案;所述钢筋焊网具体为网格状的钢筋焊网,且所述钢筋焊网的表面上还固定连接有多个交叉呈X形状的加强筋杆。
优选的,作为一种可实施方案;所述钢筋焊网的表面还涂覆有防腐涂层。
与现有技术相比,本发明实施例的优点在于:
本发明提供的一种高防水性的优质泡沫混凝土预制楼板,分析上述主要内容可知:
该泡沫混凝土预制楼板包括位于顶层的第一防水层和位于底层的第二防水层以及之间的泡沫混凝土层;该高防水性的优质泡沫混凝土预制楼板可以有效的提升其中泡沫混凝土层具有防水性、防火性、隔音性、保温节能等效果。其最为重要的是第一防水层以及第二防水层的技术:关于第一防水层:包括防水卷材和聚酯毡制成。该防水卷材层综合性能优良,特别是延伸率及抗老化性能甚佳。根据地区及用户的需求,产品可在-18℃—105℃范围内保持良好的工作状态。
关于第二防水层:单组份橡胶防水涂料的其涂膜有着与现在比较普遍使用的聚氨酯双组分防水涂料强三倍的力学性能:抗拉强度较高、延伸率高、高温稳定、低温柔软、粘结力强、防水性能优良;另外它还具有独性的自修复功能,在涂层被刺穿一段时间后会自我修复刺孔,这一特点是其他防水涂料所不可比的,这是因为它永远不会完全硫化,所以它永远有表面的粘结力。由于单组份橡胶防水涂料层最大的特性为300%定伸抗拉强度很低,只需约0.1Mpa,而断裂抗拉强度很高,达3.2Mpa。由于它具有优良的延伸率及柔软性,因此用它作为底层与找平层直接接触来适应基层变形即“零变位应力”是最好的选择,即担当了前述的“缓冲层”,此外,SBS涂料作为一种粘稠度较低的涂料,能充分有效地湿润基面、渗入基面的毛细孔,与基层达到紧密结合。
由于SBS涂料中的苯乙烯与共混卷材中氯化聚乙烯的分子结构是同质的,而且氯化聚乙烯有不饱和键,因此两者能很好地相互粘结,即两者的亲和性很好。同时,由于SBS涂料具有不硫化的特性、具有永久的表面粘结力,因此能与卷材紧密结合成为一个整体,能够成为一种高效优质的防水层,使用寿命长、防水效果好,广泛适用于建筑物、构筑物的防水或保温层。
总的来说,本发明提供的一种高防水性的优质泡沫混凝土预制楼板,其具有防水性能优越、防火性好、隔音性、保温节能佳等等诸多方面的技术优势。

下面通过具体的实施例子并结合附图对本发明做进一步的详细描述。
参见图1,本发明实施例提供的一种高防水性的优质泡沫混凝土预制楼板,包括位于顶层的第一防水层1和位于底层的第二防水层2以及设置在所述第一防水层1和第二防水层2之间的泡沫混凝土层3;所述泡沫混凝土层3夹于所述第一防水层1和所述第二防水层2之间;
其中,所述泡沫混凝土层3具体包括泡沫混凝土层本体31以及在泡沫混凝土层本体31内部分布设置有钢筋焊网32;(需要说明的是,同时,所述泡沫混凝土为以水泥作主料,以砂、石作辅料的加水浆料中掺入发泡的发泡剂组分等等成分,经过搅拌浇注成型的泡沫混凝土层。)
所述第一防水层1(具体参见图2)具体包括自上而下依次设置有防水卷材层11、聚酯层12;所述防水卷材层11与所述聚酯层12之间为固定连接;
所述第二防水层2具体(具体参见图3)包括单组份橡胶防水涂料层21、复合粘贴共混卷材层22和保护层23;所述单组份橡胶防水涂料层21与所述复合粘贴共混卷材层22紧密接触、互相融合成一体结构,两者的结合处为无缝结合。
所述泡沫混凝土层以质量份数计:所述泡沫混凝土层包括水泥20~30份;粉煤灰20~45份;硅灰3~6份;凹凸棒石粘土0~2份;化学发泡剂1~5份;稳泡剂0.03~2份;纤维0~4份;防水剂0.5~3份;早强剂0~4份;减水剂0.1~0.4份;膨胀剂0.1~4份;生石灰0~3份;水22~30份;有机高分子乳液0.5~0.9份、极性有机小分子乳液0.1~0.7份、润湿剂0.05~0.1份;所述有机高分子乳液按体积百分比计固含量≥30%;所述极性有机小分子乳液为硅烷乳液或极性硅烷衍生物乳液;所述润湿剂为磺化油、皂基或拉开粉BX;
需要说明的是,传统的泡沫混凝土制品受限于工艺问题还存在易开裂、吸水性强等缺陷,限制了其在实际工程中的应用。但是本发明的高防水性的优质泡沫混凝土预制楼板中的泡沫混凝土层,大掺量粉煤灰免蒸养超轻泡沫混凝土主要性能均优于常用的泡沫混凝土,其表观密度为160kg/m3~280kg/m3,导热系数低于0.06W/(m·K),体积吸水率不大于10%;掺入粉煤灰的比例高达47%,不仅大量降低泡沫混凝土中水泥的用量,还消除了泡沫混凝土制品因应力产生的裂纹,且有利于制品后期强度的提高,可制备出性能优良的绿色节能产品(即在浇筑至凝固过程中不产生收缩下沉、坍塌、变形、脱模时间短,工艺稳定性好,成品率高)。与此同时,其还添加了机高分子乳液、极性有机小分子乳液、润湿剂等;
上述有机高分子乳液、极性有机小分子乳液、润湿剂等混合,会渗透到混凝土或建筑砂浆中,使其中游离的氢氧化钙能够与极性有机小分子反应生成凝胶,以使混凝土或建筑砂浆表层更加密实和坚固。另外,由于润湿剂能降低乳液的表面张力,能够使所述增强剂迅速进行渗透,并能将极性有机小分子带入到表面内部,达到固结松散的砂粒作用,进一步提高了对混凝土砂浆表面加固的作用。
具体而言,所述极性有机小分子乳液为硅烷乳液或极性硅烷衍生物乳液。其中,所述极性硅烷衍生物乳液为烷氧基硅烷乳液,渗入到混凝土或建筑砂浆中后生成硅酸钙凝胶,这些凝胶能再次将粘接不牢的砂石粘接,增加了混凝土的表面的密实性,同时凝胶还可以堵塞混凝土内部的毛细孔,从而提高了混凝土表面的硬度、耐压强度和耐磨性,所以,施涂以混凝土或建筑砂浆表面后,能够有效控制混凝土表面的起砂、起灰。所述润湿剂为磺化油、皂基或拉开粉BX,能够改善待增强表面对混凝土表面的粘接力。
所述防水卷材层包括聚乙烯丙纶高分子复合阻燃防水卷材;所述防水卷材层的化学成分主要由62.5~70.4%的线性低密度聚乙烯树脂,0.5~1.5%的光屏蔽剂,0.5~1.5%的抗氧剂,0.1~0.5%的分散剂,0.5~1.0的助粘剂,28~33%的阻燃母料组成,单位为重量百分数;阻燃母料的成分主要由聚烯烙树脂80~82%、聚乙烯蜡1.5~2.5%、耦联剂14~16%、白油0.8~1.2%,硬脂酸锌0.8~1.2%组成。
需要说明的是,a、配料混合:将62.5~70.4%的线性低密度聚乙烯树脂,0.5~1.5%的光屏蔽剂,0.5~1.5%的抗氧剂,0.1~0.5%的分散剂,0.5~1.0的助粘剂,28~33%的阻燃母料放在容器内搅拌均匀,单位为重量百分数;b、一次热融直压:将搅拌好的物料加入螺杆挤出机内,经过螺杆挤出机熔融挤出成树脂膜,温度155℃~165℃;c、二次热融直压:在挤出树脂膜的同时,将无纺布从两侧同时引进一对牵伸轧辊中,通过轧辊挤压,将无纺布与树脂膜热压复合成一体,温度155℃~165℃,形成防水卷材;
上述线性低密度聚乙烯树脂主要起防水作用,选用线性低密度聚乙烯树脂的原因在于该物质具有稳定的耐化学性、耐臭氧性、抗穿刺性,较高的抗冲击强度和耐环境应力开裂性等优点,但其物理性能在光照与受热时会慢慢降解,为避免这一现象,除在施工时采用隐蔽式结构外,在配料时加入多种助剂。其中的光屏蔽剂能很好的抵抗和吸收外部紫外线;抗氧剂可有效地抑制防水卷材的氧化作用,延长其使用寿命;分散剂可确保其它助剂分散均匀,在挤出过程中充分塑化与降低熔融树脂的表面张力;助粘剂用于提高粘接强度,进而提高防水卷材的强度。无纺布不仅增加了卷材的强度,而且增强了卷材与基层和防护层间粘结的可靠性,无纺布可以采用聚酯无纺布。本发明的高防水性的优质泡沫混凝土预制楼板,其中的防水卷材层具有优良的防水性能、耐化学性、耐候性和较好的机械强度、较小的线膨胀系数,其表面粗糙均匀,摩擦系数大,重量轻,尤其是具有良好的阻燃性能。
分析本发明提供的高防水性的优质泡沫混凝土预制楼板的主要结构可知:该泡沫混凝土预制楼板包括位于顶层的第一防水层和位于底层的第二防水层以及之间的泡沫混凝土层;该高防水性的优质泡沫混凝土预制楼板可以有效的提升其中泡沫混凝土层具有防水性、防火性、隔音性、保温节能等效果。其最为重要的是第一防水层以及第二防水层的技术:关于第一防水层:包括防水卷材和聚酯毡制成。该防水卷材层综合性能优良,特别是延伸率及抗老化性能甚佳。根据地区及用户的需求,产品可在-18℃—105℃范围内保持良好的工作状态。
关于第二防水层:单组份橡胶防水涂料的其涂膜有着与现在比较普遍使用的聚氨酯双组分防水涂料强三倍的力学性能:抗拉强度较高、延伸率高、高温稳定、低温柔软、粘结力强、防水性能优良;另外它还具有独性的自修复功能,在涂层被刺穿一段时间后会自我修复刺孔,这一特点是其他防水涂料所不可比的,这是因为它永远不会完全硫化,所以它永远有表面的粘结力。由于单组份橡胶防水涂料层最大的特性为300%定伸抗拉强度很低,只需约0.1Mpa,而断裂抗拉强度很高,达3.2Mpa。由于它具有优良的延伸率及柔软性,因此用它作为底层与找平层直接接触来适应基层变形即“零变位应力”是最好的选择,即担当了前述的“缓冲层”,此外,SBS涂料作为一种粘稠度较低的涂料,能充分有效地湿润基面、渗入基面的毛细孔,与基层达到紧密结合。
由于SBS涂料中的苯乙烯与共混卷材中氯化聚乙烯的分子结构是同质的,而且氯化聚乙烯有不饱和键,因此两者能很好地相互粘结,即两者的亲和性很好。同时,由于SBS涂料具有不硫化的特性、具有永久的表面粘结力,因此能与卷材紧密结合成为一个整体,能够成为一种高效优质的防水层,使用寿命长、防水效果好,广泛适用于建筑物、构筑物的防水或保温层。
