Multi-layer efficient waterproof rolled material and its manufacturing method

Abstract

The invention relates to a multilayer high effective water proof coiled material and the manufacture method. The main feature is that it is constructed by upper coating layer, water proof base layer, water proof base plies, 1-3 sets water proof unit layer constructed by single water proof base layer, single layer water proof plies, water proof base layer, water proof plies, water proof base layer and down coating layer. Taking draught to the two layers or 3-5 layers basal plies, superposing and cutting the brim, separating the basal plies to 15-30cm until finishing the dipping mixture process, razing the rest mixture to from 0.2-0.5mm water proof basal layer, adhering coating material, the multiplayer high effective water proof coiled material would be formed. It is mainly used in construction.

Description

technical field [0001] The invention relates to a waterproof coiled material and a manufacturing method thereof, in particular to a waterproof coiled material with multiple waterproof base layers and a manufacturing method thereof. The utility model belongs to the technical field of construction engineering waterproof materials. Background technique [0002] There are many types of waterproof membranes currently used in construction projects, mainly using waterproof membranes composed of a single-layer waterproof base layer and the upper and lower waterproof base layers. Because of its excellent waterproof performance, simple construction methods and moderate prices, It has been widely recognized and widely used. However, because this type of waterproof membrane only uses a single-layer waterproof base layer, its tensile strength is relatively low, and its anti-aging performance is relatively poor. The disadvantage is that the waterproof performance is not good enough, and ...

AI Technical Summary

Problems solved by technology

However, because this type of waterproof membrane only uses a single-layer waterproof base layer, its tensile strength is relatively low, and its anti-aging performance is relatively poor. The disadvantage is that the waterproof performance is not good enough, and it is easily deformed and damaged during transportation. The service life is not long, and it can no longer meet the high standard requirements of modern construction projects for waterproof membranes

In addition, due to the short service life of the waterproof membrane, premature maintenance and replacement will inevitably lead to an increase in consumer costs and certain troubles, and more importantly, it will also pollute the environment and waste resources.
