The invention relates to a primer, a polymer pre-laid waterproof coiled material and a preparation method, the polymer pre-laid waterproof coiled material comprises a base material layer, a primer layer, an adhesive layer and an anti-sticking layer which are sequentially stacked, and the raw material formula of the primer adopted by the primer layer comprises a first emulsion and a second emulsion, the first emulsion is one or a combination of more of a butadiene-acrylic acid copolymer emulsion and a butadiene-methacrylic acid copolymer emulsion, and the second emulsion is rubber latex. Compared with an existing high-molecular pre-laid waterproof roll, the high-molecular pre-laid waterproof roll has the advantages that by using the specific primer, the degumming rate is greatly reduced in the using process; and meanwhile, compared with the existing high-molecular pre-paved waterproof roll, the high-molecular pre-paved waterproof roll disclosed by the invention also has excellent dimensional stability and tensile strength retention rate after high-temperature thermal aging.
本发明涉及一种底涂剂及其高分子预铺防水卷材和制备方法，该高分子预铺防水卷材包括依次层叠设置的基材层、底涂层、胶粘层和防粘层，该底涂层采用的底涂剂的原料配方包括第一乳液和第二乳液，第一乳液为丁二烯‑丙烯酸共聚物乳液、丁二烯‑甲基丙烯酸共聚物乳液中的一种或者多种的组合，第二乳液为橡胶胶乳。本发明的高分子预铺防水卷材通过特定底涂剂的使用，相比现有的高分子预铺防水卷才在使用过程中，脱胶率大大降低，同时相比现有的高分子预铺防水卷本发明的高分子预铺防水卷材还具有优异的尺寸稳定性和高温热老化后的拉伸强度保持率。
