Abstract

The invention relates to the technical field of waterproof coiled materials, and particularly discloses a non-asphalt-based on-site coiled material which is of a multi-layer stacked structure and sequentially comprises a first waterproof coating, a reinforced matrix layer and a second waterproof coating from bottom to top, and the first waterproof coating and the second waterproof coating are made of acrylate spraying film materials. According to the non-asphalt-based on-site coiled material, an acrylate film spraying reaction type material is adopted to replace a modified asphalt waterproof coating material serving as a main material of a waterproof coating of the existing on-site coiled material, and the original curing after moisture solvent volatilization is changed into reaction curing, so that the molding time of the waterproof coating material is greatly shortened; objective conditions such as air temperature and humidity required by construction are reduced, and the problems that an existing coiled material is inconvenient to use in low-temperature and high-humidity environments and low in drying speed are solved.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled material, and in particular relates to a non-asphalt-based ready-made coiled material and a preparation method thereof. Background technique [0002] Traditional waterproofing membranes are mainly wet-laid waterproofing membranes, self-adhesive polymer modified bitumen waterproofing membranes, elastomer modified bitumen waterproofing membranes, and polymer waterproofing membranes. The above types of products have a good waterproof effect, but the construction technology requirements are relatively high, and it is very easy to cause hollowing due to poor self-deformation ability and insufficient adhesion (such as the position of the yin and yang corners). characteristics, when coils of different lengths are connected, overlapping edges are unavoidable, especially in large-scale construction sites, where the construction area of ​​coils is large, the amount of coils is large, and the numbe...
