Abstract
The present invention relates to a buoyancy material suitable for various manned submersibles, which adopts tiny hollow glass beads extracted from waste pulverized coal ash in a power plant as basic raw materials; the basal body of the buoyancy material is composed of hollow epoxy balls, outer strengthened walls and filling materials, wherein the hollow epoxy balls are made of epoxy resin, the outer strengthened walls are coated on the hollow epoxy balls, and the filling materials are filled among the hollow epoxy balls. Experiments proves that the buoyancy material has the performance indexes that the specific gravity is smaller than 0.5, the pressure resistance is high, and the water absorption ratio is low after breakage; the present invention is suitable for manned submersibles, and has the advantages of simple manufacturing technique. The buoyancy material can be produced in batches.
Description
The present invention belongs to a kind of buoyant material that is applicable on the various manned latent devices.
At present, composite buoyancy material is divided into two classes by its structure: a class is to be that packing material is formed by adhering with epoxy resin with the artificial hollow micro glass bead, and its proportion is more greatly more than 0.54, though be used for the deep-sea device of diving, but because than great, the buoyancy that unit volume provided is little.Another kind of is to be that matrix foams with the above-mentioned material, and the skin of material carried out surface treatment with glass fabric and epoxy resin, can make proportion less than 0.5, but its superficial layer is in case after destroying, its water absorption rate increases sharply, can be up to 60%, like this after material is subjected to than high hydrostatic pressure, the safe and reliable work of device of diving can not be guaranteed, manned latent device can not be used for.And above two kinds of material preparation process complexity, cost height, domestic not production still.
Purpose of the present invention just provides a kind of new buoyant material, and its proportion is promptly less than 0.5, and withstand voltage properties is strong again, and destroying the back water absorption resistance can be good again, can be used as the buoyant material on the manned latent device.Owing to utilize the cenosphere that from the discarded fly ash in power plant, extracts to be one of raw MAT'L, make preparation technology simple, cost is low, can produce in batch.
Basic comprising of the present invention, as material structure scheme drawing (one), buoyant material matrix (1) is strengthened outer wall (3) and the mixing packing material (4) that is full of between each epoxy hollow ball is formed by epoxy hollow ball (2) and apposition at the epoxy hollow ball on the epoxy hollow ball.Epoxy hollow ball (2) is formed by epoxy resin, and it is that epoxy resin and hollow glass micropearl are formed by a certain percentage that the epoxy hollow ball is strengthened outer wall (3).Mixing packing material (4) is mixed according to a certain ratio by epoxy resin and hollow glass micropearl to be formed.Be filled in the space between each epoxy hollow ball of material matrix (1) through micro breadth oscillation.Hollow glass micropearl material wherein is to extract from the discarded fly ash in power plant.
The narration of preferred forms of the present invention:
Accompanying drawing (one) is represented the structural representation of this buoyant material.
The process for making of this buoyant material.Hollow epoxy ball (diameter 0.2～0.4mm, proportion are 0.06～0.09) two to three layers of hollow glass micropearl of adhering with epoxy resin that will prepare in advance earlier, the outer wall of formation 200～300 μ m, its bulk density is 0.12～0.14.This hollow ball is put in the mould (according to the material requested shape, size is made), carried out micro breadth oscillation, make it be full of mould.And then the hollow glass micropearl below 80 orders is filled in the mould.Carry out micro breadth oscillation equally, make it be full of the remaining space of each the epoxy hollow ball in the material matrix (1) greatly.Good seal mould then, the epoxy resin that will have curing agent with vacuum aspiration sucks in the mould, makes epoxy resin be full of space between epoxy hollow ball and the hollow glass micropearl.The buoyant material of making like this, its proportion≤0.5, surface needn't otherwise processed, can guarantee the compactness of buoyant material, light weight and withstand voltage, this material cut open arbitrarily put under the static pressure test, under the pressure of regulation (below 150 pressure), its water absorption rate≤3%, requirement up to specification, can be applicable to provides needed buoyancy on the various manned latent devices, guarantees safe and reliable work.
Claims (1)
1, a kind of buoyant material of being made up of the packing material between thin-walled hollow ball and spheroid is characterized in that: (1) hollow ball is made by epoxy resin, and strengthens its outer wall by 2～3 layers of gross thickness micro glass bead that is 200～300 μ m and the compound of epoxy resin; (2) compound formed by hollow glass micropearl and epoxy resin of the weighting material between the spheroid.
