Abstract
The present invention relates to earth working material technical fields more particularly to a kind of bentonite clay and preparation method thereof.The preparation method of bentonite waterproof blanket overlap joint clay, following steps：Asphalt is after emulsifier, with sodium bentonite, plasticizer in the reaction vessel of 180 DEG C of high temperature, using high-speed shearing machine with 280 turns per minute of rate mix 30 minutes, after raw material reaction is fused, form the clay of semi-solid black, it is packed into the sealing of glue bucket after cooling, that is, the bentonite clay of the present invention is made.Due to the adoption of the above technical scheme, bentonite clay viscosity made of the present invention is strong, after clay is smeared, it is not easy to and it is dry and cracked, fall off, make bentonite waterproof blanket that there is better waterproof, seepage control effect.
Description
Technical field
The present invention relates to earth working material technical fields more particularly to a kind of bentonite clay and preparation method thereof.
Background technology
At present in industry bentonite waterproof blanket overlapped processing generally use be bentonite clay particle and water by a certain percentage
Make the bentonite clay come.This clay needs situ configuration, and needs to be finished as early as possible, and otherwise clay will become stiff,
It can not be continuing with.In addition, this clay is easy to dehydration after smearing cause dry and cracked, the phenomenon that falling off, swelling is directly influenced
The waterproof, seepage control effect of native waterproof blanket.
Invention content
The object of the present invention is to provide a kind of bentonite waterproof blanket overlap joint clay, to solve the above technical problems.
Another object of the present invention is to provide a kind of preparation methods of bentonite waterproof blanket overlap joint clay, to solve
Above-mentioned technical problem.
Following technical scheme may be used to realize in technical problem solved by the invention：
Bentonite waterproof blanket overlap joint clay, is made of the raw material of following weight percent：
Asphalt 40%~60%；
Emulsifier 20%~40%；
Sodium bentonite 15%~18%；
Plasticizer 2%~5%.
The preparation method of bentonite waterproof blanket overlap joint clay, includes the following steps：
After asphalt is carried out emulsion reaction using emulsifier, sodium bentonite, plasticizer is added, and in reaction vessel
It is middle to use cutter mix, after raw material reaction is fused, the clay of semi-solid black is formed, the sealing of glue bucket is packed into after cooling,
The bentonite clay of the present invention is made.
The bentonite clay of the present invention can be used in use, opening glue bucket.After the present invention uses above-mentioned technique, bentonite
Clay has stronger viscosity, and the overlap joint of waterproof blanket can be allowed more secured.Also there is flexibility simultaneously, it can be well with waterproof blanket knot
It is combined, adapts to the differential settlement of ground, be that water resistance is more lasting.
The preferred asphalt of the present invention is reacted with sodium bentonite, plasticizer 180 DEG C of high temperature after emulsifier
In container, it is solid to form half after raw material reaction is fused with 280 turns per minute of rate mix 30 minutes using high-speed shearing machine
The clay of body shape black is packed into the sealing of glue bucket, that is, the bentonite clay of the present invention is made after cooling.
The proportioning that above-mentioned raw materials use for：Asphalt 40%~60%, emulsifier 20%~40%, sodium bentonite
15%~18%, plasticizer 2%~5%.
Above-mentioned raw materials optimum ratio is：Asphalt 50%, emulsifier 30%, sodium bentonite 15%, plasticizer 5%.
Advantageous effect：Due to the adoption of the above technical scheme, bentonite clay viscosity made of the present invention is strong, and clay is smeared
Afterwards, dry and cracked, obscission will not occur, make bentonite waterproof blanket that there is better waterproof, seepage control effect.
Description of the drawings
Fig. 1 is a kind of using renderings of the embodiment of the present invention 1；
Fig. 2 is a kind of using renderings of the embodiment of the present invention 2.
Specific implementation mode
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, tie below
Conjunction is specifically illustrating that the present invention is further explained.
Bentonite waterproof blanket overlap joint clay, is made of the raw material of following weight percent：Asphalt 40%~
60%, emulsifier 20%~40%, sodium bentonite 15%~18%, plasticizer 2%~5%.It is preferred that using following weight hundred
The raw material of ratio is divided to be made：Asphalt 50%, emulsifier 30%, sodium bentonite 15%, plasticizer 5%.
The preparation method of bentonite waterproof blanket overlap joint clay, takes the raw material of said ratio, using following steps：Using
After 40%~60% asphalt is carried out emulsion reaction by 20%~40% emulsifier, the sodium base of addition 15%~18% is swollen
Profit soil, 2%~5% plasticizer, in the reaction vessel of 180 DEG C of high temperature, using high-speed shearing machine with 280 turns of speed per minute
Rate mix 30 minutes forms the clay of semi-solid black, the sealing of glue bucket is packed into after cooling, that is, is made after raw material reaction is fused
At the bentonite clay of the present invention.The bentonite clay of the present invention can be used in use, opening glue bucket.The present invention is using above-mentioned
After technique, bentonite clay has stronger viscosity, and the overlap joint of waterproof blanket can be allowed more secured.Also there is flexibility simultaneously, it can be very
Good is combined together with waterproof blanket, adapts to the differential settlement of ground, is that water resistance is more lasting.
Using the bentonite clay of the present invention, the integral waterproofing effect of waterproof blanket is not only made to be improved, but also improved
Efficiency.In the past with traditional bentonite clay, 1 overlap joint that can only smear 500 square metres of areas of people 1 hour.It uses now
The bentonite clay of the present invention, 1 people 20 minutes can complete.In addition, there are no pollution to the environment for this product, there is dissemination.
Embodiment 1：
Referring to Fig.1, the present invention is in use, open glue bucket sealing cover, with long 20 centimeters, wide 4 centimeters of scraper plate directly will be swollen
Profit soil clay 1 is applied to the lap-joint of waterproof blanket 2, and the width of smearing is per 2.5 centimeters of side, and thickness is 0.5 centimeter, along overlap joint
Mouth is uniformly applied to end.
Embodiment 2：
With reference to Fig. 2, waterproof blanket turns back the waterproof blanket 2 for being overlapped on above 10 centimeters after completing, and is overlapping following waterproof blanket 2
2 centimeters of edge at, bentonite clay 1 is directly applied to edge with long 20 centimeters, wide 4 centimeters of scraper plates, the width of smearing is 5
Centimetre, thickness are 0.5 centimeter, then along uniformly end is applied at 2 centimeters of 2 edge of waterproof blanket, in the waterproof blanket 2 fold-back
It is good to turn back directly compacting overlap joint.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
