Abstract

The invention relates to a casting light composite foam floating material and a preparation method thereof. The composite foam floating material consists of a component A and a component B, wherein the component A comprises an epoxy resin, an epoxy active diluent, a surfactant, a thixotropic agent, a silane coupling agent, a foaming agent and hollow glass beads; the component B comprises a curing agent and a catalyst. The invention aims to provide a casting light composite foam floating material suitable for a casting process. The casting light composite foam floating material has the characteristics of low material viscosity, high flowing and leveling properties, high pouring and penetrating properties. The casting light composite foam floating material is suitable for pouring gaps and complex cavity structures, so that the defect that a prefabricated solid buoyancy material cannot be poured is overcome, and the casting light composite foam floating material is convenient to use and wide in application range.

Description

technical field [0001] The invention relates to a polymer-based composite foam material, in particular to a pouring type lightweight composite foam floating body material and a manufacturing method thereof. Background technique [0002] Solid buoyancy materials are important supporting materials for deep-sea development. Advanced industrial countries such as the United States, Britain, Japan, and Russia began to develop and use them in deep-sea submarine development in the 1960s. They have been widely used in civil, commercial, military and other industrial fields. The solid buoyancy material developed by the US Naval Applied Science Laboratory, when the material density is 0.35g / cm 3 , the uniaxial compressive strength is 5.5Mpa. Solid buoyancy material for 7,000-meter manned submersible developed by Emerson & Cuming of the United States, with a density of 0.561g / cm 3 At this time, it can dive to a depth of 7000 meters. In 1987, the Japan Marine Technology Center succe...
