Abstract

The invention discloses a water-based epoxy asphalt waterproof adhesive layer material and a preparation method thereof. The water-based epoxy asphalt waterproof adhesive layer material is prepared by adding expanded vermiculite powder and graphene on the basis of the traditional material, thereby greatly enhancing the impact resistance, strength and toughness of the material. The water-based epoxy asphalt waterproof adhesive layer material has favorable flame-retardant and smoke inhibition effects, so that the service life of the material is greatly prolonged; and thus, the water-based epoxy asphalt waterproof adhesive layer material is a low-cost high-performance novel waterproof adhesive layer material.

Description

technical field [0001] The invention relates to the technical field of modified asphalt, in particular to a water-based epoxy asphalt waterproof bonding layer material and a preparation method thereof. Background technique [0002] Most of the early bridge deck waterproof bonding layer materials in our country were transformed from building waterproof materials, so their classification is roughly the same as that of building waterproof materials. At present, most of the bridge deck waterproof bonding materials in my country use asphalt as the base material, mainly including roll materials and coatings. [0003] Before 2001, ordinary emulsified asphalt was the main waterproof bonding layer for expressway bridge decks in my country. Typical projects include Ninglian Expressway. However, later engineering practice has proved that this type of waterproof bonding layer cannot meet road performance requirements. [0004] In recent years, my country has also carried out research a...
