Description
技术领域
本发明涉及保温材料技术领域，具体涉及一种冬季道路施工养护用保温毡毯。
背景技术
道路的建设施工过程对温度有严格要求，不同的环境温度会影响基料的凝结效果，例如公路桥涵工程施工建设标准中，对于混凝土的出机温度要求不能低于10℃，入模温度不能低于5℃，如果温度不能达到标准，则可能会导致路基质量降低，强度不够容易破裂，达不到验收标准。
因此，在一些对工期要求较为紧迫，需要在冬季低温天气下施工的道路建设工程，路基铺设后必须进行保温处理。道路建设过程中通常采用草料袋或棉被等进行保温处理，草料袋的成本较低但是保温效果相对较差；棉被的成本高，保温效果好，易于折叠回收，但是棉被防火阻燃效果较差，在干燥的冬季一旦被引燃则难以及时扑救；另外，棉被多次使用后，表层的面料会老化破损，不能继续使用，材料的重复利用率较低。
发明内容
针对现有技术中存在的问题，本发明提供了一种冬季道路施工养护用保温毡毯，该保温毡毯的保温性能突出，阻燃效果好；材料的柔韧性较好，易于折叠或收卷，并且具有良好的耐候性，可以多次重复使用，不会破损。
为了达到上述目的，本发明通过以下技术方案来实现的：
一种冬季道路施工养护用保温毡毯，按照质量份数，保温毡毯的组分包括：改性棉纤维60-80份，丙纶纤维10-15份，聚丙烯纤维7-13份；
改性棉纤维、丙纶纤维和聚丙烯纤维使用前进行阻燃处理，阻燃处理后的纤维，经过预开松、精开松、梳理、铺网、预刺、复刺、整烫和分切打包处理后得到所需保温毡毯。
优选地，按照质量份数，保温毡毯的组分包括：改性棉纤维65-70份，丙纶纤维13-15份，聚丙烯纤维8-10份。
优选地，改性棉纤维的制备方法为：将棉纤维加入到15-20wt%的氢氧化钠溶液中，以35-45℃的温度浸泡30-40min，浸渍完成后离心脱水再漂洗至中性；漂洗浸入到无水乙醇和丙酮的等质量比混合溶液中，以40-60℃的温度超声震荡清洗10-15min，处理完成后离心脱水；然后将上步处理后的棉纤维在改性剂中浸渍处理40-60min，浸渍完成后离心脱水；得到所需的改性棉纤维。
优选地，改性剂的制备方法为：按照质量份数，将硫酸钛15-20份，尿素3-7份，钛酸丁酯1-3份，羟甲基丙烯酰胺钠3-5份，壳聚糖4-5份混合均匀，溶解于6-10倍体积的去离子水中，高速搅拌得到改性剂。
本发明中，改性棉纤维、丙纶纤维和聚丙烯纤维的阻燃处理方法如下：将改性棉纤维、丙纶纤维和聚丙烯纤维按照质量份数比混合，加入到阻燃处理罐中，将阻燃处理罐抽至真空状态，真空度为30-40kPa，保持真空状态20-30min，然后将阻燃处理液加入到阻燃处理罐中，阻燃处理液加入量以完全淹没混合纤维为准，再将处理罐中的气压加到0.8-1.5MPa，保持压力2-3h后，解除处理罐压力，将混合纤维取出，沥净水分后，在通风环境下自然干燥，完成阻燃处理过程；阻燃处理液中，按照质量份数包括以下成分：三聚氰胺15-20份，十溴二苯醚3-10份，二氧化硅溶胶15-20份，磷系阻燃物30-40份，水180-210份；磷系阻燃物选用磷酸铵、磷酸三甲苯酯和聚磷酸铵中的一种。
优选地，阻燃处理过程中，阻燃处理罐内的温度为60-70℃。
优选地，保温毡毯的厚度为20-25mm。
本发明具有如下的有益效果：
该型保温毡毯采用改性棉纤维作为主体纤维材料使用，并配合添加了少量的丙纶纤维和聚丙烯纤维，既保证了材料的保温性能，也改善了材料的强度和耐候性能，从而提高保温毡毯的使用寿命。改型保温毡毯的纤维经过改性和阻燃处理后，强度提高，并且具有良好的阻燃性能，可以降低保温毡毯在干燥的冬季被引燃的风险。
具体实施方式
下面结合实施例对本发明的具体实施方式作进一步描述，以下实施例仅用于更加清楚地说明本发明的技术方案，而不能以此来限制本发明的保护范围。
