The embodiment of the present invention provide a kind of shear thickening liquid and the preparation method of space fabric compounded protective pad, including with
Lower step:
Step 10) sews up the surface layer of warp-knitted spacer fabric periphery；
Step 20) use silicone rubber to be coated the two of warp-knitted spacer fabric surface layers and periphery suture sealing；
Step 30) curing schedule 20) process after warp-knitted spacer fabric；
Step 40) to step 30) process after warp-knitted spacer fabric in irrigate shear thickening liquid, make compounded protective pad.
By aforementioned four step, at the top layer coating silicon rubber of warp-knitted spacer fabric so that warp-knitted spacer fabric becomes
Sealing state, then irrigates shear thickening liquid in warp-knitted spacer fabric, makes compounded protective pad.When compounded protective pad is rushed
When hitting, first, in space fabric wall between paraphysis flexural deformation opposing external force, the shear thickening liquid being subsequently filled is hit
After, liquid it is converted into solid-state, substantially increases the ability of fabric opposing external force, meanwhile, shear thickening liquid is in conversion process
Absorb substantial amounts of impact energy.So, impulsive force is buffered, effectively by the shear thickening liquid in compounded protective pad
Reducing foreign impacts power to the impact liquid by preventer or human body, after external force is removed, shear thickening liquid turns again to
Liquid, the elasticity of a paraphysis makes fabric return to original state.
In the above-described embodiments, as it is shown in figure 1, described warp-knitted spacer fabric 1 includes upper layer 101, wall 102 and
Cutting optimal 104, in the middle of wall 102 layer located above 101 and cutting optimal 104, and wall 102 connect upper layer 101 and under
In the middle of surface layer 104.Warp-knitted spacer fabric includes upper layer 101, wall 102 and cutting optimal 104, has and preferably buffers effect
Really.Preferably, described surface layer uses polyester filament fiber weaving, described wall to use polyester monofilament yarn to knit
Make, 1～3 needle gage in polyester monofilament interval adjacent in wall.
Preferably, step 10) includes procedure below: warp-knitted spacer fabric is cut into pre-set dimension, then by position
Wall in warp-knitted spacer fabric periphery cuts off so that warp-knitted spacer fabric periphery forms two relative surface layers 101；Use
Sewing technology, two the relative surface layers 101 that will be located in warp-knitted spacer fabric periphery are sewed up, and form suturing part 103, and two
Hand-hole 2 and venthole 7 it is respectively kept with on individual relative limit.The wall that cutting is too much, can reduce the volume of overcoat；Cutting
Very few wall, can affect sealing effectiveness.It is preferred, therefore, that the distance that the wall cut off is away from warp-knitted spacer fabric edge
It is 10～20mm.
This preference, the wall that will be located in warp-knitted spacer fabric periphery cuts off so that warp-knitted spacer fabric periphery is formed
These two direct relative surface layers 101 are sewed up by two relative surface layers 101.The protective pad so made, periphery is two
Individual surface layer is directly sewed up, and the integraty of structure is good, improves edge hot strength.Mid portion is then connected two by wall
Surface layer forms.Carrying out step 20) operation time, by Silicone Rubber Coated when protective pad periphery, silicone rubber is applied directly to two
On surface layer, be conducive to improving the sealing effectiveness of periphery.If the wall of warp-knitted spacer fabric periphery is not cut out, then silicon
Rubber needs to be coated on wall.This is compared with this preference, on the one hand wastes silastic material, on the other hand impact resistance
Insufficient strength, easily occurs that silicone rubber is damaged, is unfavorable for sealing effectiveness.
Preferably, described step 20) include procedure below: on flat board, uniformly coat one layer of silicone rubber, will
Warp-knitted spacer fabric cutting optimal after step 10) is sewed up is placed on flat board, impregnates, then above warp-knitted spacer fabric
Layer pours silicone rubber into, carries out blade coating process so that silicone rubber dipping upper layer；Use scraper plate by the periphery fissure of warp-knitted spacer fabric
It is coated at conjunction, reserves hand-hole and venthole.
Due to step 30) in, the shear thickening liquid of liquid will be injected to warp-knitted spacer fabric, so needing warp-knitted spacer to knit

Cover periphery suture.It is to say, upper layer and the cutting optimal of warp-knitted spacer fabric are completely covered by silastic-layer.At interval
In layer 102, addition shear thickening liquid can be effectively reduced and penetrate load, plays good protective action.But shear thickening liquid
There is certain mobility, so warp-knitted spacer fabric is not packaged, then be easy to flow out.Traditional thin-film package can in case
Only it flows out, but under gravity, shear thickening liquid easily gathers at one, forming part bulge, the phenomenon in part cavity,
Affect using effect.And the present embodiment uses silastic-layer to coat upper layer and the cutting optimal of warp-knitted spacer fabric, surface layer is knitted
It is high that thing and silicone rubber constitute intensity, and the composite cover of good sealing effect, and this composite cover is by paraphysis jail between wall
It is solidly connected, does not haves bulge or lamination.
Step 20) after the upper layer and cutting optimal coating silicon rubber of warp-knitted spacer fabric, if warp-knitted spacer fabric is quiet
Put, directly it solidified, then silicone rubber still can seepage downwards, especially for the silicone rubber of coating on upper layer.
For preventing in the curing process, the downward seepage of silicone rubber, this preference provide following scheme: described step 30) include following

Being heating and curing, after silicone rubber solidifies, swivel mount stops the rotation, by warp-knitted spacer fabric from closing taking-up template.
In above-mentioned preference, the warp-knitted spacer fabric after coating silicon rubber is placed in closing template so that silicone rubber
Will not be without departing from warp-knitted spacer fabric in swivel mount rotary course.By starting swivel mount, swivel mount drives closed die
Plate and warp-knitted spacer fabric rotate so that be positioned at the work at centrifugal force of the silicone rubber in warp-knitted spacer fabric upper layer and cutting optimal
Under with, will not the silicone rubber in seepage, especially upper layer downwards.The rotating speed of conservative control swivel mount so that silicone rubber from
Under the effect of mental and physical efforts, sidepiece will not be flowed to, concentrate on the periphery of surface layer.Therefore, when swivel mount rotates, the face of warp-knitted spacer fabric
Layer is for lay up and down, and the rotary speed of swivel mount is 4～8r/min.Swivel mount rotates at a slow speed, can avoid because action of gravity is made
Become the silicone rubber in upper layer to run off and silicone rubber flows into wall, cause upper layer to seal irregular.It is being heating and curing
During process, as preferably, solidification temperature is 60～80 DEG C, and hardening time is 8～10 minutes.

Hole 7 is positioned at top, and hand-hole 2 connects shear thickening liquid container 5 by the first pipeline；By the first closedown of pipeline, and to vacuum tank 4
Carry out evacuation process；After evacuation process terminates, open the first pipeline, shear thickening liquid 6 from shear thickening liquid container 5 to warp
Compile space fabric 1 to flow into, until being full of warp-knitted spacer fabric 1, closing the first pipeline, whole warp-knitted spacer fabric 1 is taken out, and
Hand-hole 2 and venthole 7 to warp-knitted spacer fabric 1 carry out fill plug seal, make compounded protective pad.
In above-mentioned preference, by the way of evacuation, being discharged by the gas in warp-knitted spacer fabric, warp-knitted spacer is knitted
In negative pressure state in thing.The hand-hole of warp-knitted spacer fabric is positioned at bottom.Under suction function, shear thickening liquid is by being positioned at the end
The hand-hole in portion flows in the wall of warp-knitted spacer fabric from outside shear thickening liquid container.Owing to slowly injecting, and
Shear thickening liquid, under suction function, injects in warp-knitted spacer fabric from bottom to top, under self gravitation effect, and shear thickening liquid
It is not likely to produce bubble, meanwhile, when being disposed vertically warp-knitted spacer fabric, by shear thickening liquid action of gravity, it is to avoid warp-knitted spacer
The bottom of fabric or corner occur being not filled by phenomenon so that shear thickening liquid is fully filled with the wall of whole sealing, does not stays
There is space.Simultaneously as upper layer and cutting optimal are securely joined together by wall, can be effectively prevented from occurring that bulge is existing
As.This impact resistance being all conducive to improving whole compounded protective pad.
