Pouring sealant as well as preparation method and application thereof
The invention discloses a pouring sealant as well as a preparation method and application thereof. The pouring sealant is mainly prepared from the following components: matrix asphalt, PBDMS-silicon dioxide resin, rubber, tackifying resin, aggregate and an auxiliary agent, wherein the auxiliary agent comprises one or more of a coupling agent, a warm mixing agent and an anti-stripping agent. The preparation method of the pouring sealant comprises the following steps: adding the matrix asphalt, the PBDMS-silicon dioxide resin, the rubber, the tackifying resin, the aggregate and the auxiliary agent into a reaction kettle in proportion, and mixing and stirring for 30-50 minutes at the rotating speed of 100-140 rpm, so as to obtain the pouring sealant. The crack pouring sealant and crack section aggregate have good chemical compatibility and physical compatibility, the bonding force between the crack pouring sealant and a crack wall is greatly improved, and the crack pouring sealant has very high strength resistance and resilience to wheel impact and shearing within a wider temperature application range.
本发明公开了一种灌封胶及其制备方法和应用，所述灌封胶主要由以下各组分制备而成：基质沥青、PBDMS‑二氧化硅树脂、橡胶、增粘树脂、骨料和助剂；其中，助剂包括偶联剂、温拌剂、抗剥离剂中的一种或多种。灌封胶的制备方法包括以下步骤：将相应质量份数的基质沥青、PBDMS‑二氧化硅树脂、橡胶、增粘树脂、骨料和助剂按照比例加入到反应釜中，在转速100‑140rpm下混合搅拌30‑50min，即得灌封胶。上述灌缝胶和裂缝断面骨料之间具备良好的化学相容性和物理相容性，与缝壁间的粘结力得到大幅度地提高，且该灌缝胶在更宽的温度应用范围内，对车轮冲击、剪切具有非常强度抵抗力和回弹性。
