It interacts with surface, changes kaolinic interlayer and surface texture, improve swelliong power when its moisture absorption, it can be effective
Antiseepage.In addition, the present invention prepares impervious material using dedicated draft machine, preparation efficiency is high, and the thermal diffusivity of draft machine is fabulous,
Should not there is a phenomenon where scald user.
The draft machine of the present embodiment is described in detail below.As shown in Fig. 2, the draft machine 100 in the present embodiment includes head
101 and base 102, head 101 has cavity, and the mixing vessel 103 for material is equipped in cavity, and mixing vessel 103 is bucket
Shape, cavity top are equipped with nose cover 104, close mixing vessel 103 with lid, nose cover 104 is equipped with pressure valve 125, mixed with control
Close the pressure value in container 103.
Stirring rod 105 is equipped in mixing vessel 103, base 102 has closed accommodation space 106, accommodation space 106
The first cooling space 107 is formed between outer wall and the inner wall of base, the bottom of the first cooling space 107 is provided with exhaust vent 108, holds
It receives and is equipped with the partition 110 with the first intercommunicating pore 109 in space 107, partition 110 divides accommodation space 106 for upper accommodation space
111 and lower accommodation space 112, upper accommodation space 111 and lower accommodation space 112 be connected tos by the first intercommunicating pore 109, lower receiving sky
Between 112 bottom there is air inlet hole 113, be equipped with driving body 114 in lower accommodation space 112, driving body 114 can be motor, drive
The top of kinetoplast 114 is equipped with upper drive rod 115, upper drive rod 115 sequentially pass through after accommodation space 111, mixing vessel 103 with
Stirring rod 105 is sequentially connected, and has gap between the bottom of stirring rod 105 and the bottom of mixing vessel 103, to prevent from rubbing,
And the cross sectional dimensions of stirring rod 105 successively decreases from inside to outside, to improve mixing effect, because material is often pushed in mixing vessel
103 bottoms middle position increase stirring rod 105 close to the size in 103 bottom middle position of mixing vessel, conducive to stirring efficiency
It improves.The lower part of driving body 114 is equipped with lower drive rod 116, and lower drive rod 116 is sequentially connected with impeller 117, and impeller 117 is main
For driving wind to recycle, heat dissipation is realized.It is electromagnetic coil, 103 bottom of mixing vessel packet that upper accommodation space 111, which is equipped with electric circle 118,
It is covered with metal dish 119, electric circle 118 is controlled by a controller generation alternating magnetic field and metal dish 119 is generated heat, and metal dish 119 has
Bottom wall and side wall, bottom wall are close to the bottom of mixing vessel 103, and side wall is close to the side wall of 103 lower part of mixing vessel, to mixing
Container 103 carries out three-dimensional heating, and heating efficiency is high.The upper lateral part of upper accommodation space 111 have the second intercommunicating pore 120, second
Intercommunicating pore 120 is communicated with the first cooling space 107, and when so that draft machine working, electric circle 118 generates heat to metal dish 119, is driven simultaneously
Kinetoplast 114 drives stirring rod 105 and impeller 117 to rotate, and stirring rod 105 stirs the material in mixing vessel 103, and impeller 117 will
External wind sucks lower accommodation space 112 from air inlet hole 113 and cools down to driving body 114, and it is right to subsequently enter accommodation space 111
Electric circle 118 is cooling, finally enters the first cooling space 107 and is discharged by exhaust vent 108 and (participates in arrow flow direction in Fig. 2), makes
The present embodiment draft machine 100 can continuous work, smoothly complete and repeatedly prepare modified kaolin, the reason is that, driving body
When 114 drive stirring rods 105 continue working, driving body 114 can generate more heat transfer, and electric circle 118 also can in the course of work
It generates heat must not obtain and distribute if these heats are persistently accumulated, it may occur that failure.Since the heat that driving body 114 generates is remote
Much larger than the heat that electric circle 118 generates, therefore the heat dissipation of driving body 114 is the most urgent, thus impeller 117 by external wind from air inlet hole
113, which first suck lower accommodation spaces 112, cools down driving body 114, it is ensured that the temperature of driving body 114 is not too high, then with
The cooling wind that heat exchange occurs for driving body 114 can enter upper accommodation space 111 to the cooling of electric circle 118, and it is cooling to finally enter first
Space 107 is simultaneously discharged by exhaust vent 108, and driving body 114 and electric circle 118 are respectively placed in different skies by this cooling mechanism
Between, both on the one hand can guarantee that working temperature environment is different, on the other hand can be realized first driving body 114 is carried out it is sufficiently cold
But.
In order to further increase cooling effect, the cross section of the first cooling space 107 is gradually increased in turn from top to bottom,
Such as the angle between 107 outer wall of the first cooling space and vertical direction is 3-4 °, is convenient for 108 air draft of exhaust vent in this way, so that
Inside forms negative pressure, is conducive to air inlet hole 113 and enters the wind, and accelerates cold wind circulation.Air outlet 108 is located at the periphery of air inlet 113, into
Air port 113 be located at the lower section of impeller 117 and be in impeller 117 periphery, the first intercommunicating pore 109 be located at the lower section of electric circle 118 and
It encloses, convenient for being come into full contact with to electric circle 118, radiates to electric circle 118, which passes through electric circle frame 121 in electric circle 118
Around upper drive rod 115, electric circle frame 121 is socketed on drive rod 115, and electric circle 118 is wound on electric circle frame 121.By
In the effect of impeller 117, therefore the temperature of the outer wall of the base 102 of the present embodiment is not too high, will not occur to scald phenomenon.For
To guarantee the outer wall of head 101 will not occur to scald phenomenon, outer wall and head 101 of the present embodiment in mixing vessel 103
The second cooling space 122 is formed between inner wall, passes through third connecting between the second cooling space 122 and the first cooling space 107
Hole 123 is connected to, and the outer wall of mixing vessel 103 is also provided with the 4th intercommunicating pore 124 being connected to the second cooling space 122, third
Intercommunicating pore 123 be it is up big and down small, when 108 air draft of exhaust vent, can make at third connecting hole 123 formed Venturi effect, make
The second cooling space 122 can be entered from third connecting hole 123 by obtaining extraneous cold wind, it is ensured that the temperature of the outer wall of head 101 will not be very
Height will not scald user, and the cross section of the second cooling space 122 is successively gradually reduced from top to bottom, so that cold wind is abundant
It radiates to head 101.
When preparing modified kaolin, the kaolin of 50 parts by weight is placed in mixing vessel 103, the not work of driving body 114
Make, so that stirring rod 105 and impeller 117 do not work, only electric circle 118 works, and when so that mixing vessel 103 being warming up to 105 DEG C, protects
Temperature 7 minutes, then by the copolymer nylon of 25 parts by weight and 1 parts by weight of crosslinking agent, 1 parts by weight initiator, 1 parts by weight distilled water
It is mixed into reaction dissolvent, crosslinking agent selects N, N- methylene-bisacrylamide, and initiator selects benzoyl peroxide amide, then will reaction
Solvent is added in mixing vessel 103, and by electric circle 118 by heating and temperature control at 150 DEG C, driving body 114 works, stirring rod
105 stirrings 9 minutes, the work air draught of impeller 117 finally control mixing vessel 103 and are cooled to 100 DEG C, it is stearic that 0.5 parts by weight are added
Acid.
The present invention is not limited to above-mentioned specific embodiment, those skilled in the art from the above idea,
Without creative labor, made various transformation are within the scope of the present invention.
