▎ 摘 要
NOVELTY - Gel material comprises carbon nanomaterial and silicate cement, where the carbon nanomaterial comprises carbon dots and carbon dot-modified oxidation graphene. The particle size of the carbon dots is 3-20 nm. The particle size of the carbon dot-modified graphene oxide is 50-1000 nm. The mass ratio of the carbon nanomaterial to the silicate cement is 0.0001-0.3:1. The carbon dots comprise graphene quantum dots and/or carbon quantum dots. The groups contained on the surface of the carbon dots further comprises nitrogen-containing groups and silane groups. USE - The gel material is useful for building anti-corrosion in coastal environment of high temperature environment and sea water soaking for a long time and the service life. ADVANTAGE - The gel material: does not need to add additional dispersant or other additive; greatly improves the chloride ion curing rate of the gel material, compared with the common silicate cement; and has excellent anti-corrosion performance and mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of gel material. DESCRIPTION OF DRAWING(S) - The drawing shows a preparation flow chart of the gel material.
