Reactive polymer self-adhesive waterproof coiled material and preparation method thereof

Abstract

The invention discloses a reactive polymer self-adhesive waterproof coiled material and a preparation method thereof, belonging to the field of waterproof technology. The reactive polymer self-adhesive waterproof coiled material comprises a sterilization layer, a flame-retardant layer, a waterproof layer, a substrate layer and a PE protective layer. The sterilization layer comprises the followingraw materials in parts by weight: 60 to 75 parts of polyurethane, 10 to 25 parts of gypsum, 15 to 28 parts of quick lime, 15 to 20 parts of attapulgite clay, 10 to 30 parts of acrylate, 5 to 10 partsof graphene oxide, 3 to 8 parts of nanometer zinc oxide, 10 to 15 parts of a modifier, 1 to 5 parts of a curing agent and 1 to 5 parts of a coagulant. The flame-retardant layer is prepared from the following raw materials in parts by weight: 65-70 parts of polypropylene, 3-7 parts of a flame retardant, 4-7 parts of a dispersing agent, 3-5 parts of a toughening agent and 10-15 parts of titanium dioxide. The firmness of the waterproof coiled material with the bactericidal effect can be greatly improved, the phenomena of collapse and water leakage of the waterproof coiled material due to bacterium breeding of the waterproof coiled material are avoided, and the waterproof coiled material has good application prospects.

Description

technical field [0001] The invention belongs to the field of waterproof systems, in particular to a reactive polymer self-adhesive waterproof roll and a preparation method thereof. Background technique [0002] Waterproof roll material is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering foundation and building There is no leakage connection between objects, which is the first barrier for waterproofing of the whole project and plays a vital role in the whole project. The self-adhesive waterproof membranes in the prior art are often researched and developed in depth in terms of bonding performance, low-temperature flexibility, and self-healing properties, but there are few self-adhesive waterproof membranes with good sterilization and flame-retardant effects on the market. Contents of the invention [0003] Aiming ...
