Description

technical field [0001] The invention relates to the technical field of solid buoyant materials, in particular to a low-density, high-strength solid buoyant material in shallow water and a preparation method thereof. Background technique [0002] In recent years, my country's marine technology has developed rapidly, and great progress has been made in marine exploration and testing. The detection and development of marine resources is inseparable from marine equipment, and marine equipment requires buoyancy materials to provide net buoyancy. The density and pressure resistance of buoyancy materials The strength directly determines the working performance and working depth of marine equipment. Low-density high-strength buoyancy materials have become an important part of the development of modern diving technology. [0003] At present, the main performance related parameters of domestic solid buoyancy materials are: density 0.36-0.7g / cm 3 , Hydrostatic pressure resistance 2-150...
