High-barrier pre-laid waterproof impervious coiled material
The invention discloses a high-barrier pre-laid waterproof impervious coiled material, the overall thickness of the coiled material is greater than or equal to 1.2 mm, the coiled material comprises a main body material, a hot melt adhesive layer and a sand grain anti-sticking layer, the thickness of the main body material is greater than or equal to 0.70 mm, and the thickness of the hot melt adhesive layer is greater than or equal to 0.25 mm; the main body material is formed by co-extrusion of HDPE and EVOH resin, the number of co-extrusion layers of the main body material is larger than or equal to 3, the HDPE layers and the EVOH layers are arranged in a stacked and crossed mode, and the outermost layer of the main body material is the HDPE layer. According to the high-barrier pre-laid waterproof anti-permeability coiled material, the barrier property of the coiled material to methane gas can be effectively improved, and therefore the health and safety performance of a building are improved.
本发明公开了一种高阻隔预铺防水抗渗卷材，所述卷材的整体厚度大于等于1.2mm，且卷材包括主体材料、热熔胶层和砂粒防粘层，其中，所述主体材料的厚度大于等于0.70mm，所述热熔胶层的厚度大于等于0.25mm；所述主体材料通过HDPE和EVOH树脂共挤而成，该主体材料的共挤层数大于等于3层，其中，HDPE层和EVOH层层叠交叉设置，且主体材料的最外层为HDPE层。本发明一种高阻隔预铺防水抗渗卷材，能够有效提高卷材对甲烷气体的阻隔性，从而提高建筑健康和安全性能。
