Abstract

The invention relates to the technical field of waterproof materials. In order to solve the problems of poor fracture resistance and tensile properties of existing waterproof materials during construction and use, a high-efficiency waterproof material for tunnels and a preparation method thereof are provided. The high-efficiency waterproof material includes the following components: filler, modified paraffin, modified rubber, polyvinyl chloride, antioxidant, tackifier, coupled modified bamboo charcoal fiber, and polyacrylonitrile fiber. In the present invention, modified rubber is also added to the filler, and the modified rubber is first put into a sodium hydroxide solution for soaking and passivation treatment, and then the passivation-treated rubber is reacted with an anionic surfactant, and the anionic surface active agent is used to react with the modified rubber. The surface of the rubber is modified by the agent, so that the rubber can be fully contacted with the graphene oxide and the silicon-hydrogen compound, and the graphene oxide and the silicon-hydrogen compound are grafted on the surface of the rubber, which increases the ductility and strength of the rubber.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, in particular to a high-efficiency waterproof material for tunnels and a preparation method thereof. Background technique [0002] Waterproof materials are the materials used in the building envelope to prevent the infiltration of rainwater, snow water and groundwater into the building, and are commonly used building materials in tunnel construction and maintenance. There are many kinds of waterproof materials, including: asphalt waterproof materials, rubber and plastic waterproof materials, cement waterproof materials, and metal waterproof materials. The existing waterproof materials for tunnels have poor fracture resistance and tensile properties during construction and use, which leads to the situation that the waterproof layer formed by the waterproof material is pulled and broken during the construction process, resulting in poor waterproof effect.
