Specific implementation mode
The following is a clear and complete description of the technical scheme in the embodiments of the invention, it is clear that described embodiment
Only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this field
The every other embodiment that art personnel are obtained, shall fall within the protection scope of the present invention.
Embodiment
An embodiment of the present invention provides a kind of preparation method of the prestressed material of anticollision damping, this method includes in preparing
Empty sphere simultaneously prepares coagulator；The hollow sphere is using any one material in metal, rubber, plastics, ceramics, glass
It is made；The coagulator is any one in metal liquid, rubber liquid, plastic liquid, cement mortar；In practical system
When making, the material of the hollow sphere is metal, and the coagulator is metal liquid；A diameter of the 0.4 of the hollow sphere~
0.6 centimetre, the wall thickness of the hollow sphere is 0.08~0.12 centimetre.The fusing point of the hollow sphere material is higher than the solidification
Agent material fusing point；The hollow sphere is to be made using structure of transvers plate method.The hollow sphere is using structure of transvers plate method
It is made.The template that the structure of transvers plate method uses is organic formwork or inorganic template.It is described it is organic for phenoplasts it is miniature
Any one in ball, polystyrene tiny balls；The inorganic template includes hollow ceramic powder, hollow glass microbead, Ni hollow
Any one in microballoon.Method using nickel hydroxide as template construct hollow sphere includes：The NiSO that will be prepared4With
NaON solution heats and stirs production Ni in a water bath（OH）2Colloidal solution；NaH is added into the colloidal solution2PO2Solution
Both the hollow metal ball.With Ni（OH）2Colloid is as template, since it is with elecrtonegativity, one layer of Adsorption on Surface
Ni2+Ion, which is colloid surface, has catalytic effect identical with W metal, then NaH is added into colloidal solution2PO2Solution, when
H2PO2 -When ion diffuses to colloid surface, Ni2+Ion and H2PO2 -The reduction reaction of ion is catalyzed around colloid, the Ni of generation
Colloid outside at first formed layer of Ni net, it is online that the Ni generated later is just deposited on Ni.With the continuous deposition of Ni, intermediate glue
Core is constantly consumed, is dissolved, and is finally disappeared.The advantages of this method is that the disappearance of the deposition and template of metal is carried out at the same time, and is compared
Traditional structure of transvers plate method, without in addition finding template, without removing template is removed after metallization, reaction time is short, mouldability
It is good, and can by control the ion concentration in reaction solution concentration and reaction solution control products therefrom granule size and
Size distribution.
After the compounding substances are poured into molding die, certain pressure is applied to the molding die and keeps certain
Time；

Gu agent is constituted；There are pressure differences with extraneous gas pressure for the hollow sphere internal gas pressure.Gas pressure intensity in bead is big
In extraneous pressure, to reach prestressed effect；The structure of matter also will present most can a kind of measuring body structure.It coagulates under high pressure
Gu the air pressure after solidification in sphere can be more than external pressure, it is in critical external compressive resistance state, generates outside prestressing force effect;Do not exist
It is solidified under high pressure, the air pressure after solidification in sphere is less than external pressure, is in stretch-proof state, generates inside prestressing force effect
Fruit;The prestressing force of generation is outward or inside, is realized by external pressure.It simultaneously can also be by filling not jljl in sphere
Matter is apt to its material character to make.
Material provided by the present application, if hollow beads be under high pressure coagulation forming when, the gas pressure intensity in bead
More than extraneous pressure, air pressure in the sphere after solidification is made to be more than external pressure, then hollow sphere is in critical external compressive resistance state, generates
Outside prestressing force effect;If the external pressure applied is relatively low, in the sphere after solidification air pressure be less than external pressure, then in
Empty sphere is in stretch-proof state, generates inside prestressing force effect;To reach prestressed effect, while its structure of matter
Can be most can a kind of measuring body structure.The elastic properties of materials is good, and anti-pressure ability is big, and anti-corrosion ability is strong, and service life is long, from heavy and light material
Material province etc..
