Flame retardant solid buoyancy material and preparation method thereof

Abstract

The invention relates to the technical field of a solid buoyancy material used in a marine environment and specifically to a flame retardant solid buoyancy material and a preparation method thereof. The flame retardant solid buoyancy material comprises, by mass, 100 parts of an epoxy resin, 15 to 30 parts of a halogen-containing fire retardant, 7 to 15 parts of an inorganic fire retardant, 12 to 20 parts of an active flame retardant diluent, 1 to 4 parts of a foaming agent, 0.15 to 0.3 part of a wetting dispersant, 0.5 to 1 part of an accelerator, 90 to 130 parts of a curing agent and 20 to 150 parts of hollow glass beads. The flame retardant solid buoyancy material provided in the invention has the characteristic of flame retardation, can be used in deep sea, is free of loss of net buoyancy and is processable.

Description

technical field [0001] The invention relates to the technical field of solid buoyancy materials for marine environments, in particular to a method for preparing a solid buoyancy material with flame-retardant properties and the flame-retardant solid buoyancy material prepared by the method and applicable to water surface to deep sea environments. Background technique [0002] With the development of my country's economy, the continuous improvement of marine science and marine technology, the frequency of marine scientific research, investigation, measurement and other activities has increased significantly, making solid buoyant materials widely used, and then equipped with ships and warehouses that store solid buoyant materials The fire risk of places such as the place also increases greatly. One of the important measures to prevent fires and reduce fire losses by relying on the level of science and technology is to use solid buoyancy materials with flame-retardant properties....

AI Technical Summary

Problems solved by technology

[0007] In the known technology, none of the solid buoyant materials serving the ocean has flame retardant properties, which cannot meet the requirements of flame retardant safety.

After a lot of experiments, the inventor prepared a flame-retardant solid buoyancy material by using a modified matrix resin and a curing agent. This scheme has not yet been disclosed in relevant literature.
