Self-adhesive rubber waterproof coiled material and preparation method thereof
The invention discloses a self-adhesive rubber waterproof coiled material which is prepared from the following raw materials in parts by weight: 20 to 25 parts of butyl rubber, 2 to 4 parts of carbon black, 28 to 35 parts of polyisobutene, 30 to 35 parts of ethylene propylene diene monomer, 5 to 8 parts of white oil, 10 to 15 parts of light calcium carbonate, 7.1 to 7.5 parts of accelerant and 5.5 to 6.5 parts of modified anti-aging agent. The invention also discloses a preparation method of the waterproof coiled material, the preparation method comprises the following steps: 1, putting the raw materials into a kneading machine, kneading for 15-30 minutes at 80-120 DEG C, cooling, and carrying out extrusion molding on an extruder to obtain a butyl rubber self-adhesive layer; and 2, arranging an isolation paper on the butyl rubber self-adhesive layer for isolation and curling to obtain the self-adhesive rubber waterproof coiled material. The micromolecular anti-aging agent is combined with the silica sol, the molecular weight of the anti-aging agent is increased, the migration resistance is improved, and the anti-aging effect is achieved so that the anti-aging performance of the base material is improved, and the service life of the self-adhesive coiled material is prolonged.
本发明公开了一种自粘橡胶防水卷材，包括如下重量份的原料：丁基橡胶20‑25份、炭黑2‑4份、聚异丁烯28‑35份、三元乙丙橡胶30‑35份、白油5‑8份、轻质碳酸钙10‑15份、促进剂7.1‑7.5份、改性防老剂5.5‑6.5份；本发明还公开了该防水卷材的制备方法，第一步将原料置于捏合机中，在80‑120℃条件下捏合15‑30mi n，冷却后在挤出机上挤出成型，得到丁基橡胶自粘层；第二步在丁基橡胶自粘层上设置隔离纸进行隔离卷曲，得到自粘橡胶防水卷材。本发明中将小分子的防老剂与硅溶胶结合，增加防老剂的分子量，提高耐迁移性，发挥抗老化的作用，从而改善基材的耐老化性能，延长自粘卷材的使用寿命。
