Abstract

The invention relates to a machinable solid buoyancy material and a preparation method thereof. The machinable solid buoyancy material belongs to a functional nonmetallic material and comprises the following components in part by mass: 100 parts of epoxy resin, 15 to 55 parts of amine epoxy curing agent and 30 to 130 parts of glass beads, wherein the epoxy resin is bisphenol S type epoxy resin or glycidol epoxy resin; and the amine epoxy curing agent is polyamide 650, polyamide 651, tertiary nitrogen type organic amine or quaternary nitrogen type organic amine, bismaleimide, low molecular weight polyacrylamide, imidazoles or organic acid anhydride compounds. The preparation method comprises the following steps of: heating the epoxy resin and the amine epoxy curing agent, weighing the epoxy resin and the amine epoxy curing agent, blending and stirring the epoxy resin and the amine epoxy curing agent, adding the glass beads, stirring again, kneading the materials, after taking the material out, coating a mould release agent on the inner wall of a die and sticking mould release paper; filling the material into the die; covering by using a cover; curing the die in a drying oven; and separating the material from the die on a demoulding machine. The machinable solid buoyancy material can meet the requirements on underwater projects, permanent buoys and the like.

Description

technical field [0001] The invention relates to a processable solid buoyancy material and a preparation method thereof, belonging to functional non-metallic materials. Background technique [0002] Machinable solid buoyant materials began to be studied in the 1980s. So far, developed countries such as Japan and the United States are in a leading position. Some institutions in my country have also conducted research, but so far, no scale production has been formed, and there is no sale of this product on the market. It is different from general non-metallic materials such as plastics, glass, rubber, foaming materials, wood products, ceramics, etc., in that it has the properties of light weight, high strength, and can be machined. It also has sound insulation, heat insulation, and high and low temperature resistance. , Corrosion resistance, resistance to various water immersion. The main application areas are underwater engineering, permanent buoys and other equipment and eq...
