Abstract

The invention relates to the technical field of building materials, and discloses a pre-laid waterproof roll as well as a preparation method and application thereof. The pre-laid waterproof roll comprises an anti-radiation coating, a polymer sheet layer, a pressure-sensitive adhesive layer and an isolating layer which are sequentially stacked, wherein a first material composition for forming the anti-radiation coating contains an emulsion, water and an active component in a weight ratio of 1: (0.5-3): (0.5-3); and a second material composition for forming the polymer sheet layer contains two or more selected from the following components which are stored in a mixed manner or are independently stored: resin, an anti-radiation modifier, a bridging agent, an activating agent, an antioxidant and a color masterbatch. The pre-paved waterproof roll provided by the invention not only has an excellent anti-ionizing radiation effect, but also has excellent aging resistance and low temperature resistance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a pre-paved waterproof coiled material and its preparation method and application. Background technique [0002] At present, the number of nuclear power plants in China ranks first in the world. Qinshan Nuclear Power Plant, Guangdong Daya Bay Nuclear Power Plant, Tianwan Nuclear Power Plant, Ling Ao Nuclear Power Plant have been put into use, and the number of nuclear power plants under construction is also increasing day by day. With the increasing number of nuclear power plants, nuclear safety is getting more and more attention. [0003] Nuclear radiation is the flow of microscopic particles released during the transition of atomic nuclei from one structure or one energy state to another structure or another energy state. Nuclear radiation can ionize or excite matter, so it is called ionizing radiation. Among them, ionizing radiation is divided into direct ionizing...
