Problems solved by technology

It takes too long to cure at room temperature, usually more than 1 day, and even more than a week to achieve the best performance; while curing at high temperature is often difficult to control, because the addition of hollow glass microspheres makes the buoyant material a thermal insulation Insulation materials, the thermal conductivity becomes very low, which makes it difficult to achieve the same curing temperature inside and outside the material, making the curing inconsistent, easy to generate internal stress, and the material is prone to cracking during use. A large amount of heat is often released in the air. If the internal heat is not removed in time, it is easy to cause heartburn, which makes the buoyancy material scrapped.

Abstract

The invention provides a method for quickly preparing deep-sea buoyance material by utilizing an electron accelerator. Two auxiliaries which are cationic photoinitiator and a multi-vinyl radiosensitizer in the materials are used to quickly increase epoxy resin cross-linking density and curing velocity, so that a buoyance material formula system which is 1cm thick is quickly cured within 5 minutes, and the material performance can reach the performance reached by the conventional method. The prepared solid buoyance material can be respectively applicable to sea depth of 1000 meters and 3000 meters.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a method for rapidly preparing deep-sea buoyancy materials by using an electron accelerator. The prepared deep-sea buoyancy materials can provide buoyancy for marine development equipment such as offshore oil exploitation risers and underwater operating submersibles. Background technique [0002] The solid buoyancy material technology organically combines the low-density and high-strength properties of the material, making it incomparably superior in the field of ocean development technology. Solid buoyant materials have been used in the following fields due to their superior performance: (1) Deep sea carrying and operating equipment such as China's "Jiaolong" 7000m deep submersible and China's "CR-02" self-made underwater robot. (2) Offshore oil exploitation systems such as risers and oil pipelines. (3) Marine survey and detection systems such as submerged mark systems. (4) ...
