Description

technical field [0001] The invention belongs to the technical field of anti-corrosion materials, and in particular relates to a graphene-modified high-weather-resistance and high-resilience nano-polymer gap-filling material and a preparation method thereof. Background technique [0002] At present, most of the joint filling materials in my country are mainly two-component modified tar-based materials, polysulfide, etc., and the biggest reason for using them is their low cost. With the current society's emphasis on environmentally friendly materials, the existing low-cost materials themselves contain toxic and harmful substances, and the caulking materials that contain harmful volatile substances will gradually be eliminated. [0003] Moreover, the existing caulking materials have poor weather resistance, especially those that need to be exposed to the outdoors for a long time, and it is particularly necessary to enhance the weather resistance. caulk.
