Abstract

The invention relates to the technical field of waterproof materials, and provides an efficient waterproof material for tunnels and a preparation method thereof in order to solve the problem that an existing waterproof material is poor in fracture resistance and tensile property during construction. The efficient waterproof material for tunnels is prepared from the following components: filler, modified paraffin, modified rubber, polyvinyl chloride, an antioxidant, a tackifier, coupling modified bamboo charcoal fibers and polyacrylonitrile fibers. Modified rubber is further added into the filler, the modified rubber is firstly put into a sodium hydroxide solution to be soaked and passivated, then the passivated rubber reacts with an anionic surfactant, the surface of the rubber is modified through the anionic surfactant, the rubber can be in full contact with graphene oxide and a silicon-hydrogen compound, and the graphene oxide and the silicon-hydrogen compound are grafted on the surface of the rubber, so that the ductility and the strength of the rubber are improved.

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 material is the building envelope to prevent rainwater, snowwater and groundwater from penetrating into the building. It is a building material commonly used 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. Existing waterproof materials for tunnels have poor fracture resistance and tensile properties during construction and use, resulting in the waterproof layer formed by the waterproof materials being pulled and broken during construction, resulting in poor waterproof effects. Contents of the invention [0003] The object of the present invention is to solve the s...
