Self-adhesive macromolecular pre-paved waterproof coiled material and preparation method thereof
The invention relates to a self-adhesive high-molecular pre-paved waterproof coiled material and a preparation method thereof, and the self-adhesive high-molecular pre-paved waterproof coiled material comprises an isolation sand layer, an isolation membrane layer, a hot-melt pressure-sensitive adhesive layer, a base material, a hot-melt pressure-sensitive adhesive layer and an isolation membrane layer which are sequentially stacked from top to bottom, the base material comprises a modified emulsion layer, a co-extrusion additional layer, a main body material layer, a co-extrusion additional layer and a modified emulsion layer which are sequentially stacked from top to bottom. According to the invention, the defect that a testing method of the existing pre-paved waterproof coiled material is not applicable due to the fact that the existing pre-paved waterproof coiled material adopts a method of adding a blocking layer to block migration of a plasticizer of an adhesive layer is overcome, and the structure and the system formula of the base material are improved; through the interlayer structure of the modified emulsion layer, the co-extrusion additional layer, the main body material layer, the co-extrusion additional layer and the modified emulsion layer, the pre-paved waterproof coiled material has the advantages that low molecular weight substances in the hot-melt pressure-sensitive adhesive layer can be effectively prevented from being migrated into a base material, the size change rate is low, the thermal aging peel strength is high, and the pre-paved waterproof coiled material is suitable for an existing pre-paved waterproof coiled material testing method.
本发明涉及一种自粘高分子预铺防水卷材及其制备方法，包括自上而下依次叠设的隔离砂层、隔离膜层、热熔压敏胶层、基材、热熔压敏胶层以及隔离膜层，其中，基材包括自上而下依次叠设的改性乳液层、共挤附加层、主体材料层、共挤附加层以及改性乳液层。该发明克服了现有预铺防水卷材采用增加阻隔层以阻隔胶粘层增塑剂迁移的做法，存在不适用现行预铺防水卷材的测试方法的缺点，改良基材的结构和体系配方，通过改性乳液层‑共挤附加层‑主体材料层‑共挤附加层‑改性乳液层的夹层结构，具有能有效阻止热熔压敏胶层中低分子量物质迁移到基材中、且低尺寸变化率、高热老化剥离强度、适用于现有预铺防水卷材测试方法的有点的优点。
