Description
技术领域
本申请属于复合材料技术领域,具体涉及抗水分散型聚氨酯硬质泡沫注浆止水加固材料及制备方法。
背景技术
隧道和矿山工程中时常遇到突涌水现象,易造成围岩失稳、边坡塌滑等灾害,不仅造成人员伤亡、财产损失、工期延误,还会影响工程结构的长期稳定性、恶化施工条件和破坏周边生态环境。注浆止水加固技术是改善松散或含水地层力学性能与稳定性,以及预防和治理塌方、渗漏、涌水、突泥和流沙等最常用、最有效的手段之一。
目前,常用的注浆材料主要有水泥基无机注浆材料以及脲醛树脂注浆材料、丙烯酰胺注浆材料、环氧树脂注浆材料和聚氨酯注浆材料等高分子有机注浆材料。水泥基注浆原料易得、价格低廉、结石体强度高、抗渗性能好,适用于较大裂隙的破碎岩体的大批量注浆;但是凝胶时间长、易流失浪费、可注性较差、强度增长慢、结石率低、抗水分散性差,难以用于治理突涌水;脲醛树脂注浆材料强度低,耐久性差;丙烯酰胺类注浆材料毒性较大;环氧树脂注浆材料成本高,粘度大,可注性较差。相比之下,聚氨酯注浆材料强度较高、固化时间短且可调、施工方便快捷、粘度低、流动性好、渗透性高、膨胀率高、抬升力大、抗渗堵漏加固等能力强,是一种综合性能优良的新型止水加固注浆材料,正逐渐获得广泛应用。
聚氨酯注浆材料可分为水反应性和非水反应性,水反应性聚氨酯浆液遇水膨胀并凝固,适用于常规堵漏处理,但是易被水冲散,难以封堵涌水或射流,且固化过程需有水参与反应以及固结体易水解的特点导致其强度和耐久性较差,对工程的长期稳定性造成潜在威胁;非水反应性聚氨酯浆液疏水性和耐水解稳定性好,性能稳定,不受注浆环境水含量的影响,适用于封堵涌水或射流,但仍存在抗水分散性较差的问题,易造成对水源和周边生态环境的污染。

本申请还提出了抗水分散型聚氨酯硬质泡沫注浆止水加固材料的制备方法,所述制备方法包括如下步骤:
制备所述A组分时,先将7~14重量份数的聚醋酸乙烯酯溶解于4~10重量份数的溶剂,再与210~230重量份数的异氰酸酯混合搅拌均匀,最后加入0~10重量份的发泡剂,混合后搅拌至混合物成为均匀透明液体,得到A组分;
制备所述B组分时,向混合器中加入100重量份的聚合物多元醇、20~25重量份数的增塑剂、10~27重量份数的扩链剂、1~2重量份数的泡沫稳定剂和1~1.5重量份数的催化剂并混合搅拌均匀,再加入0~10重量份的发泡剂,混合后搅拌至混合物成为均匀透明液体,得到B组分;
使用时,将所述组分A和组分B按比例混合后搅拌均匀,即可获得所述的抗水分散型聚氨酯硬质泡沫注浆止水加固材料。
需要说明地是,用溶剂溶解聚醋酸乙烯酯(PVAC)时,可将溶剂先加热到50℃~90℃并保持温度不低于50℃,再向其中边搅拌边加入聚醋酸乙烯酯,搅拌至混合物变为均质的、无颗粒的半透明高黏度液体,或将聚醋酸乙烯酯加入常温的溶剂中并在不低于20℃的环境中密封静置24~120h,得到半透明高黏度液体;将聚醋酸乙烯酯溶液加入异氰酸酯时,需预先将聚醋酸乙烯酯溶液和异氰酸酯都加热到40℃以上,优选地,将聚醋酸乙烯酯溶液加热到60℃以上,向预先加热好的异氰酸酯中边搅拌边加入预先加热好的聚醋酸乙烯酯溶液,加入聚醋酸乙烯酯溶液后继续搅拌至混合物转变为透明的深色液体;发泡剂加在A组分和B组分其中的一个中,或分别加在A组分和B组分中,优选地,若所用的发泡剂与异氰酸酯难以互溶,或加入A组分后会造成A组分黏度上升或聚醋酸乙烯酯析出,则该发泡剂应加在B组分中,若所用的发泡剂与异氰酸酯可互溶且加入A组分后不会造成A组分黏度上升和聚醋酸乙烯酯析出,则将发泡剂加入(或相对较多地加入)未加发泡剂时黏度相对较高的组分中,使加入发泡剂后A组分和B组分黏度尽可能相近。
与现有技术相比,本申请具有如下技术效果:
(1)本申请通过A组分和B组分混合后聚醋酸乙烯酯析出的物理变化使浆液黏度上升从而提高浆液的抗水分散性能,与传统的直接在A组分或B组分中加入增黏剂、填料、树脂使A组分或B组分黏度增大的抗水分散型聚氨酯注浆止水加固材料相比,本申请抗水分散型聚氨酯硬质泡沫注浆止水加固材料的A组分和B组分黏度更小,仅在A组分和B组分接触后混合物黏度才开始增大,因此使用注浆泵进行注浆的过程中,能耗更小,且A组分和B组分更易混匀;与传统的增大催化剂用量,加速凝胶反应,使浆液黏度迅速增大的抗水分散型聚氨酯注浆止水加固材料相比,本申请抗水分散型聚氨酯硬质泡沫注浆止水加固材料的聚醋酸乙烯酯析出的物理变化更温和可控,无明显放热,不会造成浆液固化过快和浆液过热,保证充足的注浆操作时间以及施工安全性。
(2)本申请抗水分散型聚氨酯硬质泡沫注浆止水加固材料具有良好的抗水分散性,在流动的水体中不易被水冲散,且强度高,纯泡沫抗压强度不小于2MPa,耐久性好,固化时间可调,价格低廉,适用于封堵涌水和射流,具有良好的经济性、安全性和环保性。
(3)本申请通过各原料的物理与化学协同作用,保证浆液在水中注浆过程中的抗水分散性和水不敏感性,进而起到止水与加固的作用,可应用于隧道突涌水的封堵工程。

表1:不同实施例抗水分散型聚氨酯硬质泡沫注浆止水加固材料的抗压强度和抗水分散性测试结果
由上述表1可见,本申请抗水分散型聚氨酯硬质泡沫注浆止水加固材料具有抗水分散性好、抗压强度高的特点,纯泡沫抗压强度不小于2MPa,因此能发挥较好的止水加固效果,适用于封堵涌水和射流,具有良好的经济性、安全性和环保性。
本申请中的A组分中含有聚醋酸乙烯酯,B组分中含有酯类增塑剂,当A组分和B组分混合时,酯类增塑剂使聚醋酸乙烯酯部分析出,使混合物的黏度迅速增大,进而提高浆液的抗水分散性能。
本申请通过A组分和B组分混合后聚醋酸乙烯酯析出的物理变化使浆液黏度上升从而提高浆液的抗水分散性能,与传统的直接在A组分或B组分中加入增黏剂、填料、树脂使A组分或B组分黏度增大的抗水分散型聚氨酯注浆止水加固材料相比,本申请抗水分散型聚氨酯硬质泡沫注浆止水加固材料的A组分和B组分黏度更小,仅在A组分和B组分接触后混合物黏度才开始增大,因此使用注浆泵进行注浆的过程中,能耗更小,且A组分和B组分更易混匀;与传统的增大催化剂用量,加速凝胶反应,使浆液黏度迅速增大的抗水分散型聚氨酯注浆止水加固材料相比,本申请抗水分散型聚氨酯硬质泡沫注浆止水加固材料的聚醋酸乙烯酯析出的物理变化更温和可控,无明显放热,不会造成浆液固化过快和浆液过热,保证充足的注浆操作时间以及施工安全性。本申请抗水分散型聚氨酯硬质泡沫注浆止水加固材料具有良好的抗水分散性,在流动的水体中不易被水冲散,且强度高,纯泡沫抗压强度不小于2MPa,耐久性好,固化时间可调,价格低廉,适用于封堵涌水和射流,具有良好的经济性、安全性和环保性。本申请通过各原料的物理与化学协同作用,保证浆液在水中注浆过程中的抗水分散性和水不敏感性,进而起到止水与加固的作用,可应用于隧道突涌水的封堵工程。
以上实施例仅用以说明本申请的技术方案而非限定,参照较佳实施例对本申请进行了详细说明。本领域的普通技术人员应当理解,可以对本申请的技术方案进行修改或等同替换,而不脱离本申请技术方案的精神和范围,均应涵盖在本申请的权利要求范围内。
