Description
技术领域:
本发明涉及一种建筑防护用品,尤其涉及安全防护网。
背景技术:
在建筑施工过程中,必须在建筑物的外围搭建筑防护网,通过防护网实现对工作人员的施工安全,避免建筑材料掉落而伤及工作人员。目前在建筑防护网都是密目式安全立网,其材质都是用聚氯乙烯或锦纶长丝等有机高分子材料纱线由经编编织成安全网体,用这类网体材料做成的建筑防护安全网通常只能使用一次,因为聚氯乙烯或锦纶等高分子纱线材料在80℃左右出现软化现象,在140℃左右发生粘流现象,如遇明火或暗火火源都极易引发火灾安全事故,造成人员伤亡和财产损失,同时在户外容易老化,撕裂强力随时间的衰减速度大,不能重复使用,这样不仅增加了建筑施工单位的安全防护成本,而且安全也难以得到保证。在安装方式上,塑料网都是通过绳子将网体的边缘扣系在钢管上,构成,将塑料网通过脚手架围护在施工现场、危险区域或建筑物周围。现在存在的问题是:大家使用的防护网因是塑料丝质品,工作人员围护时有些部位塌落严重,不仅造成使用周期短、复用率低,容易钩破,使其损坏严重,而且造成防护网的防护强度弱,在抵御、缓冲掉落物品的力度小,如果是重物,很容易将整片防护网拉下,很难起到防护的作用。而且防护网在安装在脚手架一般是通过绳子系住,安装不牢固和拆卸不方便,同时还存在安全隐患,所以提供一种建筑安全防护网来解决上述出现的问题十分有必要。
发明内容:
为解决现有安全防护密目网存在的防火等通级低,易老化等技术缺陷,申请人研发了一种高强度阻燃型耐冲击可重复使用的安全防护网,它质量轻、强度高、阻燃性能好,耐高温,熔化温度1400℃,耐酸碱,抗腐蚀、耐老化,耐折叠、耐磨,可重复使用。
本发明采取的技术方案如下:
一种高强度阻燃型耐冲击可重复使用的安全防护网,其特征是:包括玻璃纤维织造的玻纤复合网基材、强化承载折边、拉扣和强化承载索,在玻纤复合网基材的玻纤经纱和玻纤纬纱的外表面通过涂覆复合涂层浆料形成增强阻燃复合层,所述复合涂层浆料的组份及重量含量为:
强化承载折边设置在玻纤复合网基材的四周,它是在玻纤复合网基材的四周通过等宽折边方式获得,并用纵向和横向的缝合线强化缝合,强化承载索夹持在强化承载折边内;拉扣间隔分布并固定在强化承载折边上,强化承载索设置在拉扣的外侧。
进一步,在上述方案中,涂覆复合涂层浆的各组份的重量含量为:固含量≥30%的水溶性PP乳液30%~35%,磷氮类无卤阻燃剂5%~10%;涂料类色浆0.5%~1%,其余为水。
进一步,在上述方案中,涂覆复合涂层浆的各组份的重量含量为:固含量≥30%的水溶性PP乳液60%~70%;磷氮类无卤阻燃剂20%~25%;涂料类色浆3%~5%,其余为水。
所述复合涂层浆料的配制方法为:先将磷氮类无卤阻燃剂倒入水中搅拌调匀,在搅拌状态下依次加入PP乳液和色浆,搅拌均匀后即得到复合涂层浆料。
玻纤复合网基材中玻纤经纱和玻纤纬纱铰织成的玻纤网布用复合涂层浆料进行的复合方法为:
将复合涂层浆料通过浸渍涂复或喷涂方式涂覆在玻纤网布上,然后经过烘干方式使复合涂层浆料依附在玻纤经纱和玻纤纬纱上形成增强阻燃复合层,其中,增强阻燃复合层的重量占玻纤复合网基材总重量的5%~50%。
进一步,在玻纤复合网基材和复合涂层浆料的复合步骤中:烘干温度为50℃~200℃;烘干速度为1~70米/分;增强阻燃复合层的重量占比优选10%~15%。
更进一步,在玻纤复合网基材和复合涂层浆料的复合步骤中:烘干温度场为10℃~150℃;烘干速度为15~20米/分;增强阻燃复合层的重量占比为25%~30%。
由于玻纤网布是由无碱玻璃纤维通过机织获得的,因此它的阻燃性能特别好,在玻纤网布上用特种复合涂层浆料进行复合,所得的阻燃高强度玻璃纤维复合网材料不仅质量轻、强度高、耐冲击,阻燃性能好,熔化温度达1400℃,而且耐酸碱,抗腐蚀、耐老化,柔软性好,抗折,耐磨。
将现有的塑料防护网材料和本发明制成同样大小的防护网,试样防护网的尺寸为:长度6米,宽度1.8米进行对比性试验,试验结果如下表:
通过试验可以得到如下结论:
由于无碱玻璃纤维属于无机不燃物材料,用无碱玻璃纤维织造而成的绞织结构的玻纤网基材其阻燃性能极好,再用特种复合涂层浆料对玻纤织网基材进行涂覆、烘干和固化处理,便在玻纤织造网基材的表面形成高强度阻燃保护层,在保留玻璃纤维织网基材的高强度性、不燃烧性能、抗腐蚀、抗老化等性能的基础上提高了玻纤复合网基材的柔软性、耐冲击性能和抗折耐磨性能,这样既十分理想地满足了密目式安全立网的防火性能要求,又满足重复使用的抗冲击强度要求,还满足重复使用所具备的反复收展技术要求,抗腐蚀、抗老化性能的大幅度提高,是之重复使用的必要技术条件,用本发明制作的建筑防护网能更好地防止火灾安全事故发生,避免重物坠落造成人员伤亡和财产损失,安全防护等级高,能重复使用。

在本例中,涂覆复合涂层浆的各组份的重量含量为:固含量≥30%的水溶性PP乳液30%~35%,磷氮类无卤阻燃剂5%~10%;涂料类色浆0.5%~1%,其余为水。
所述复合涂层浆料的配制方法为:先将磷氮类无卤阻燃剂倒入水中搅拌调匀,在搅拌状态下依次加入PP乳液和色浆,搅拌均匀后即得到复合涂层浆料。
玻纤复合网基材1中玻纤经纱11和玻纤纬纱12铰织成的玻纤网布用复合涂层浆料进行的复合方法为:
将复合涂层浆料通过浸渍涂复或喷涂方式涂覆在玻纤网布上,然后经过烘干方式使复合涂层浆料依附在玻纤经纱11和玻纤纬纱12上形成增强阻燃复合层13,其中,增强阻燃复合层13的重量占玻纤复合网基材1总重量的5%~50%。
