Macromolecular self-adhesive film waterproof coiled material and preparation method thereof

Abstract

The invention relates to the field of waterproof materials for buildings, and particularly discloses a macromolecular self-adhesive film waterproof coiled material and a preparation method thereof. The macromolecular self-adhesive film waterproof coiled material sequentially comprises a base layer, a self-adhesive layer and an anti-adhesive layer, wherein the self-adhesive layer comprises the following raw materials: an SBS resin, a tackifying resin, a softener, 4, 4-dicarboxyl diphenylethylene, an antioxidant and an initiator. The preparation method comprises the following steps: S1, preparing raw materials of an self-adhesive layer; and S2, preparing a waterproof coiled material. According to the invention, 4, 4-dicarboxyl diphenylethylene and an initiator are adopted to initiate an SBS resin macromolecular chain to generate chain free radicals, the chain free radicals react with the 4, 4-dicarboxyl diphenylethylene to generate a graft polymer, the carboxyl in the graft polymer can chemically react with calcium hydroxide in building concrete, and the carboxyl and calcium hydroxide are combined through chemical bonds, so that the bonding tightness between the waterproof coiled material and a building is improved, skin type waterproofing is formed, and the water channeling phenomenon can be reduced when the waterproof coiled material is locally damaged.

Description

technical field [0001] The application relates to the field of waterproof materials for construction, more specifically, it relates to a polymer self-adhesive film waterproof roll and a preparation method thereof.

At present, the commonly used waterproof membrane for construction is SBS waterproof membrane, and the construction of SBS waterproof membrane is also a common waterproof method in current construction projects. The introduction of SBS has given new vitality to the domestic waterproof market, but with the development of the times, SBS waterproof membrane construction has been unable to meet the waterproof needs of current buildings

[0003] As far as the current actual situation of SBS waterproof membrane construction is concerned, when the waterproof layer is damaged, groundwater will flow between the waterproof layer and the building structure layer. The building structure layer is generally made by pouring concrete, because concrete is porous. Inhomogeneous materials, during the pouring process, there will be defects such as honeycomb holes caused by inaccurate vibration, concrete reserved gaps (construction joints, deformation joints, etc.) caused by objective factors, and structural cracks caused by uneven settlement of the foundation. The water channeling between the waterproof layer and the structural layer will enter the structure along the cracks, holes and other defects in the concrete, resulting in water channeling, which will lead to building leakage, which will easily affect the quality and efficiency of building waterproofing construction, and restrict It hinders the development of building waterproof membrane and needs to be improved
