Latest Patents
One of his latest innovations is an underwater rapid repair material for marine steel structures. This material comprises 20 to 50 parts by weight of an alkali activation material, 3 to 12 parts by weight of a fast hardening waterborne polymer curing agent, 2 to 8 parts by weight of a fast hardening waterborne polymer precursor, 30 to 100 parts by weight of an aggregate, 1 to 5 parts by weight of an activator, and 3 to 20 parts by weight of water. The underwater rapid repair material is designed to remain stable in water, with an initial setting time as low as 0.5 hours and a final setting time of 1.1 hours. After three hours of pouring, the compressive strength and flexural strength can reach approximately 60 MPa and 10 MPa, respectively. This material exhibits high bonding strength to steel and is resistant to detachment after solidification.
Another significant patent is for a concrete interface agent, which relates to the technical field of concrete surface protection. The ingredients of this agent include 55 to 100 parts by weight of a nano-calcium salt solution and a nano-SiO precursor, 0.1 to 0.4 parts by weight of a surfactant, 30 to 60 parts by weight of a silane coupling agent, and 10 to 40 parts by weight of polydimethylsilane. The nano-calcium salt solution consists of 2 to 5 parts by weight of calcium hydroxide, 2 to 5 parts by weight of an acid catalyst, and 200 to 500 parts by weight of an alcohol-based organic solvent. This agent forms a coating layer with a higher hydrophobic angle on the concrete surface, reducing water absorption and enhancing durability compared to existing TEOS interface agents.
