Butyl pressure-sensitive adhesive, preparation method thereof and waterproof coiled material
The invention discloses a butyl pressure-sensitive adhesive, a preparation method thereof and a waterproof coiled material. The butyl pressure-sensitive adhesive provided by the invention comprises the following raw material components in parts by weight: 20 parts by weight of butyl rubber; 3-15 parts by weight of polar rubber, and the polar rubber comprises acrylate rubber and chloroprene rubber; 1-3 parts by weight of a cross-linking agent; 0.5 to 1.5 parts by weight of a crosslinking accelerator; 35 to 45 parts by weight of tackifying resin; 20-30 parts by weight of a plasticizer; 1-3 parts by weight of an anti-aging agent; and 5-15 parts by weight of a filler. By introducing polar rubber, a cross-linking agent and other components into a butyl pressure-sensitive adhesive material system, the polarity and surface energy of the material can be improved, and a three-dimensional network cross-linked structure can be generated, so that the wettability and adhesion between the butyl pressure-sensitive adhesive and an adhesive are improved, and meanwhile, the waterproof coiled material is endowed with excellent waterproof performance. In addition, the preparation method of the butyl pressure-sensitive adhesive provided by the invention is simple in process, short in time consumption and low in equipment requirement, can be well compatible with the existing process, and has great large-scale application potential.
本申请公开了一种丁基压敏胶及其制备方法和防水卷材。本申请的丁基压敏胶，包括按重量份计的如下原料组份：丁基橡胶，20重量份；极性橡胶，3‑15重量份，其中，所述极性橡胶包括丙烯酸酯橡胶和氯丁橡胶；交联剂，1‑3重量份；交联促进剂，0.5‑1.5重量份；增粘树脂，35‑45重量份；增塑剂，20‑30重量份；防老剂，1‑3重量份；填料，5‑15重量份。本身请通过向丁基压敏胶材料体系中引入极性橡胶和交联剂等成分，可以提高材料的极性、表面能以及产生三维网状交联结构，进而提升丁基压敏胶与粘接物间的浸润性和粘接性，同时赋予防水卷材优异的防水性能。此外，本申请提供的丁基压敏胶的制备方法工序简单，耗时短，对设备要求低，能很好兼容现有工艺，极具大规模应用潜力。
