Abstract

The invention discloses a high-strength solid buoyancy material. The high-strength solid buoyancy material is prepared by using the following raw materials, by mass, 50-80 parts of an epoxy resin, 30-40 parts of a curing agent, 6-12 parts of liquid polysulfide rubber, 9-18 parts of a coupling agent and 25-45 parts of a hollow glass bead. The material is a high-compression-resistance low-density solid buoyancy material, has the advantages of low cost, no water absorption after long-time immersion in water, and strong use reliability, is suitable for popularization and application, can substitute imported materials to a large extent, and breaks through the situation that the market is monopolized by a small amount of foreign companies.

Description

Technical field: [0001] The invention relates to a high-strength solid buoyancy material. Background technique: [0002] Foreign countries have started research on high-strength buoyancy materials since the 1960s. At present, only a few countries such as the United States, Japan, and Russia have solved the technical problems of buoyancy materials for 6000m underwater and formed a series of products. Domestic research on buoyant materials started relatively late, and there have been some research reports in recent years, but they are far behind the level of foreign countries. Buoyancy materials with a density of 0.75g / cm3 and a compressive strength of 69.0MPa have been published. Domestic buoyancy materials generally use polyurethane foam, epoxy resin or other foamed plastics, which generally have high cost, low compressive strength, will lose buoyancy after soaking in water for a period of time, and have poor reliability. Its success But with the development of society, hi...
