Embodiment 1

[0024] Preparation of semi-cylindrical buoyancy material:

[0025] (1) VS5500 hollow glass beads were treated with KH-560 coupling agent. Mix the coupling agent and anhydrous ethanol evenly, the mass fraction of the coupling agent is 10-20wt%, then add the selected hollow glass microbeads into the ethanol solution of the coupling agent in the proportion of 1wt%, go through reflux washing, suction filtration and washing After a series of operations such as drying, the modified hollow glass microspheres are obtained.

[0026] (2) Add the weighed E-51 resin, polyamide 300# curing agent and JX-017 diluent into the vacuum mixer according to the mass ratio of 100::70:2, and the vacuum stirring time at room temperature is 5min. The liquid was stirred evenly and the foam was removed, and then the weighed modified hollow glass microspheres (180 parts) were added, and the vacuum stirring was continued for 10 min under normal temperature conditions.

[0027] (3) Fill the mixed and vacu...

Embodiment 2

[0032] Preparation of hemispherical floating body (diameter 60cm)

[0033] The raw materials and processes of Example 2 are basically the same as those of Example 1. The differences are as follows: (1) The hemispherical floating body is filled in two steps. (2) The hollow glass microspheres used are HGS8000X, and the mass fraction relative to the epoxy resin is 150 parts.

[0034] For the hemispherical floating body prepared in this example, the mass of the buoyant material is measured by an electronic scale, and the corresponding volume is obtained by measuring the size of the buoyant material with a caliper and a tape measure, and the calculated density is 0.53 g / cm 3 , the water absorption rate was 0.42% under 30MPa hydrostatic pressure for 6 hours.

Abstract

The invention relates to preparation of a buoyancy material of an integral forming process, in particular to a preparation method of a lightweight integrated composite material. The first purpose of the invention is to solve the problem of large heat release in the curing process of a large-volume buoyancy material under the condition of normal-temperature curing, and to provide a preparation process for filling a mold step by step and multiple times. According to the step-by-step multi-time filling process, the one-time filling amount is controlled within a certain thickness, heat released in the curing process of the product can be diffused in time, and the quality of the product cannot be reduced. The second purpose of the invention is to solve the problem of complex process of a large-size floating body with a simple size, and a one-step forming preparation process is provided. A floating body is basically formed by bonding and processing buoyancy material standard modules, and the preparation process provided by the invention omits the bonding processing procedure, simplifies the preparation process and improves the production efficiency of products.

Description

technical field [0001] The invention relates to the field of light-weight pressure-resistant composite materials, and mainly relates to pressure-resistant composite materials for shallow seas. Background technique [0002] The floating body for marine equipment is mainly prepared by hollow glass microspheres filled with epoxy resin through a certain preparation process. Since the 21st century, countries around the world have stepped up the exploration and exploitation of marine mineral resources and monitoring of the marine environment. As an important supporting material for deep-sea equipment, solid buoyancy materials mainly provide buoyancy and a certain strength. At present, most of the floating bodies are mainly made of buoyant material standard modules through the bonding process to form a specific shape of the floating body. The present invention is mainly aimed at the floating body having a regular shape and a large volume or a large number, and a floating body tha...
