Submersible vehicle encapsulation composite foam filling materials and preparation method thereof

Abstract

The invention discloses submersible vehicle encapsulation composite foam filling materials and a preparation method of the submersible vehicle encapsulation composite foam filling materials. The filling materials are composed of epoxy resin, polyether amine curing agents, silane coupling agents, polysiloxane defoamer, catalysts, thixotropic agents and hollow micro glass beads. The preparation method includes the steps of (1) pre-mixing of liquid materials, (2) preparation of slurry, (3) high-pressure air-free pouring, and (4) curing and performance test. The composite foam filling materials are low in system viscosity, good in flowing levelling property, long in construction period and suitable for a pouring encapsulation process, and can be cured at room temperature, the curing reaction heat release temperature peak is low, and condensate is tenacious, high in strength, small in contracting rate and good in adhesive property with steel and other materials. The composite foam filling materials are resistant to sea water soaking corrosion, good in effect after being tried, and suitable for encapsulation filling and water insulation sealing of a submarine non-water-sealing structure, a buoy, a subsurface buoy and other marine submersible vehicles.

Description

technical field [0001] The invention relates to a composite foam filling material, belonging to the category of marine solid buoyancy materials, in particular to a method for manufacturing a lightweight pressure-resistant filling material filled with hollow glass microspheres and epoxy resin. Background technique [0002] At present, marine exploration technology is an important part of the development and utilization of marine resources. Low-density, high-hydrostatic pressure-resistant deep-sea solid buoyancy materials are important materials for marine exploration technology. In order to provide marine submersibles with structural stability, sealing and hydrostatic pressure resistance performance, requiring pourable lightweight pressure-resistant fill materials to complement prefabricated solid buoyant materials. The lightweight pressure-resistant filling material developed abroad is made of high-strength resin as the matrix, filled with buoyancy adjustment medium as the m...
