Description
Technical field
The invention belongs to field of compound material.In particular it relates to the present invention relates to a kind of extremely-low density, low suction
Water rate, the solid buoyancy material of high withstand voltage intensity are it is adaptable to underwater instrument equipment provides buoyancy.
Background technology
Pressure light high-strength buoyancy material typically adopts the method preparation of light hollow microballon potting resin at present, in order to drop
Its global density low, generally to be realized using the less light hollow microballon of the more light hollow microballons of filling or packed density.
And for many years, optimized by various fill process, light hollow microballon loading oneself close to the limit, if it is micro- to be further added by light hollow
Pearl loading, the uncured front solvent or diluent viscosity of buoyant material excessive it is impossible to deaeration, light hollow microballon bulk density is as little as
0.02g/cm3, its weight accounting be less than less than 5%, light hollow microballon bulk density oneself close to the limit.Develop further
The lower high intensity buoyancy material of density is absorbed in bottleneck.A kind of high-strength solid buoyancy material of extremely-low density and manufacture method meaning are provided
Great.
Content of the invention
The technical problem to be solved is to provide a kind of extremely-low density, high-strength, high tenacity solid buoyancy material.
The technical scheme is that：
A kind of composite buoyancy material, its quality component is as follows：
Resin：100 parts；
Firming agent：60 parts；
Dispersant：0.5 part；
Coupling agent：2 parts；
Cenosphere：5.5-25 part；
Foam microspheres 1-2 part.
Further, above-mentioned resin is low-viscosity bisphenol A-type 6002 epoxy resin.
Further, above-mentioned hair-strengthening agent is methyl tetrahydrophthalic anhydride.
Further, above-mentioned dispersant preferred molecular weight 300～2000 scopes unsaturation polynary carboxylic ester polymer with
The mixture of organosiloxane copolymer.
Further, the preferred gamma-amino propoxyl group triethoxysilane of above-mentioned coupling agent.
Further, above-mentioned cenosphere is selected in hollow glass bead, ceramic hollow microballon or polymeric hollow microballon
One or more.
Further, in 10～150um, compressive resistance controls in 0.5～1.7MP the size controlling of above-mentioned cenosphere
A scope, bulk density controls in 0.02～0.07g/cm3Scope.
Further, above-mentioned foam microspheres are the foam microspheres of the lc/238 of 70-110 DEG C of blowing temperature.
The buoyant material beneficial effect of the present invention is：
Relatively general high intensity buoyancy material, under the conditions of still possessing compared with high water pressure resistance power and extremely low water absorption rate, density maximum can drop
Low by about 1/3, toughness（Elongation at break）It is substantially improved（Maximum lift 2-5 times）.
Under 80-85 DEG C of temperature conditionss, foam microspheres outer wall softens buoyant material solvent or diluent, and interior bag low boiling point hydrocarbon gas
Change, volume significantly expands, produce pressure, force its volume significantly to expand.
Innovative point explanation：1）Heat up after taking deaeration and foam microspheres are expanded into hollow beads from small particle, increase whole
Body hollow beads addition, has broken away from tradition and has added hollow beads only before deaeration, can not excessive have been required by deaeration viscosity, limits
The bottleneck of the addition of hollow beads；
2）Tradition adds hollow beads spherical, such as Fig. 1 the 1st width figure that is hard, and it is larger to pile up clearence degree between ball and ball, and this
Before foam microspheres thermal expansion hollow microsphere solidification in scheme of the invention, ball wall is soft state, when it is contacted with other hollow microspheres,
Its perfection laminating can be ensured by certain deflection, further gap between filling hollow beads, reduce resin in buoyant material and contain
Amount ratio, thus be conducive to reducing buoyant material density further；
3）Foam microspheres ball wall is thermoplastic resin, helpful for the toughness improving buoyant material, and fracture is greatly improved
Percentage elongation.
