A kind of graphene self-adhesive film root blocking waterproof membrane

Abstract

The invention discloses a graphene self-adhesive glue film root-resistant waterproof coiled material. The coiled material sequentially comprises an upper rubber film, an SEBS self-adhesive glue layerand a lower rubber film from top to bottom. The upper rubber film and the lower rubber film are crossed layer HDPE pressing films. The SEBS self-adhesive glue layer is prepared from, by weight, 38-49parts of asphalt, 51-69 parts of SEBS rubber, 13-21 parts of graphene nanosheets, 6-15 parts of root-resistant agent and 0.2-0.8 part of naphthenic oil. The coiled material has high root piercing resistance, and various other properties including low-temperature flexibility, tensile performance, tearing performance, the glass strength between the coiled material and the coiled material and the glass strength between the coiled material and post-pouring concrete of the whole product can all be improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a graphene self-adhesive film root-blocking waterproof coiled material. Background technique [0002] At present, for large-scale building waterproof construction, waterproof membrane has become the material of choice. Traditional asphalt-based waterproofing membranes or modified asphalt waterproofing membranes are usually constructed using the hot-melt method, but this construction method is easily affected by environmental factors and cannot be constructed in wet or rainy weather; at the same time, the hot-melt method uses open flame construction, which has Security risks. Nowadays, many big cities have banned the use of open flames in construction, which puts forward higher requirements for manufacturers of waterproof membranes. [0003] In the long-term work practice, the existing waterproof membranes have found some shortcomings: 1. Ordinary PE film ...

Problems solved by technology

[0003] In the long-term work practice, the existing waterproof membranes have found some shortcomings: 1. Ordinary PE film self-adhesive membranes will wrinkle when encountering temperature changes after paving, resulting in a very unsightly surface, and When the deformation is too large, it is easy to cause the cushion layer to be torn or the overlapping joints to be destroyed, thereby weakening the waterproof effect; 2. The mechanical mortise and tenon bonding between the polymer self-adhesive waterproof membrane and the concrete base is mainly formed by physical adsorption, and the bonding The force is not strong enough, the bond is not durable
