Example Embodiment

[0035] Hereinafter, the present invention is further described through several sets of typical embodiments, but the present invention is not limited to these embodiments.

[0036] The oxygen index refers to the minimum oxygen concentration required for flaming combustion of a material in an oxygen-nitrogen mixed gas stream under specified conditions. It is expressed as the value of the volume percentage occupied by oxygen. A high oxygen index indicates that the material is not easy to burn, and a low oxygen index indicates that the material is easy to burn. It is generally considered that an oxygen index 27 is a flame-retardant material. The test standard adopted by the oxygen index test method of the present invention is the national standard GB2406 combustion test-oxygen index test method.

[0037] The density test of the present invention refers to the method 5.1A of GB / T1033.1-2008 "Determination of the Density of Plastic Non-foam Plastics": Dipping Method. The specific meth...

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....
