Embodiment
, below will be in the embodiment of the present invention to make the purpose, technical scheme and advantage of the embodiment of the present invention clearer
Technical scheme be clearly and completely described.Unreceipted actual conditions person, builds according to normal condition or manufacturer in embodiment
The condition of view is carried out.Agents useful for same or the unreceipted production firm person of instrument, it is the conventional production that can be obtained by commercially available purchase
Product.
High expansion function environmental protection bentonite of the embodiment of the present invention and preparation method thereof is specifically described below.
A kind of high expansion function environmental protection bentonite, its raw material mainly include the following components counted in parts by weight：
The bentonite of 60-75 parts, the repefral of 7-12 parts, the glass fibre of 11-18 parts, the silicon of 3-5 parts
Diatomaceous earth, the polyethylene glycol of 3-8 parts, copolymerization hydrolysate, the polyacrylic acid of 3-7 parts of the ethyl acetate of 15-25 parts and acrylate
Sodium and the polyester fiber of 3-7 parts, the zinc oxide of 1-4 parts.
In other embodiments of the invention, above-mentioned raw materials also include：The sulphur of 2-6 parts and the vulcanization of 0.4-1.3 parts
Accelerator.
Repefral is that one kind has very strong solvent plasticizer, has good film forming, adherence and prevents
It is water-based.
The copolymerization hydrolysate of ethyl acetate and acrylate is the polymer of ethyl acetate and acrylate, and polymer has portion
Divide hydrolysis.
The copolymerization hydrolysate and polyethylene glycol of Sodium Polyacrylate, ethyl acetate and acrylate contain hydrophilic radical,
Hydrophilic radical has higher water-swelling property.In addition, there is above-mentioned substance preferably dispersiveness, the side chain of molecule can intert
Into in bentonitic internal voids, increase bentonitic water-swelling property.
Glass fibre is a kind of inorganic non-metallic material of excellent performance, and advantage is that good insulating, heat resistance are strong, anticorrosive
Good, the high mechanical strength of property, but shortcoming is that property is crisp, and wearability is poor.But remaining material to fragility and can wear no resistance
Shortcoming is supplied, synergy.
Diatomite is by unbodied SiO2Composition, and contain a small amount of Fe2O3、CaO、MgO、Al2O3And organic impurities.Diatomite
With special loose structure, therefore, inside diatomite there are multiple spaces that can intert for polymer substance.Polymer substance
End chain can stretch out above-mentioned space, increase its water swellability while reducing temporary volume.
Sulphur and vulcanization accelerator can increase crosslink density, and crosslink density increase can make cross-linked network finer and close,
The movement or expansion of strand can expand.Generation expansive force is big after the copolymerization hydrolysate of ethyl acetate and acrylate absorbs water
In the restraining force of cross-linked network, make the molecule after crosslinking that there is stronger water absorbing capacity, so that expansion rate of water absorption increases.
Further, above-mentioned bentonite is at least one of sodium bentonite, calcium-base bentonite and lithium bentonite.
Preferably, bentonite is sodium bentonite, and sodium bentonite absorption speed is slow but water absorption rate and expansion multiple are big.
In other embodiments of the invention, above-mentioned bentonite is acidified treated；In detail, using sulfuric acid, carbonic acid
The mixed solution of sodium and polyvinyl alcohol carries out acidification to bentonite.
Further, the copolymerization hydrolysate by Sodium Polyacrylate, ethyl acetate and acrylate and polyethylene glycol meeting
Cross-linking reaction is carried out, cross-linking reaction product has hydrophilic radical.Cross-linking reaction product interts, is inlaid into bentonite and diatomite
Internal voids；Glass fibre element is improved the mechanical strength of whole system.Make final high expansion function environmental protection swelling
The expansion character of soil is good, while increases the persistence after its expansion.
The present invention also provides a kind of technical scheme：
Above-mentioned high expansion function environmental protection preparation method for bentonite, it includes：
By copolymerization hydrolysate, Sodium Polyacrylate, polyester fiber and the oxidation of polyethylene glycol, ethyl acetate and acrylate
Zinc is reacted to obtain intermediate product.
Bentonite, repefral, diatomite are added into addition glass fibre after intermediate product is well mixed to mix
Refining.
From the above, copolymerization hydrolysate, Sodium Polyacrylate, the polyester fiber of polyethylene glycol, ethyl acetate and acrylate
And zinc oxide carries out cross-linking reaction and obtains intermediate product.Further, in other embodiments, cross-linking reaction can be according to anti-
The time answered is properly joined into initiator,
Repefral can increase the crosslink density of intermediate product and the network knot of product as thickener
Structure.Diatomite can increase water suction and the water retention property of whole system.
Intermediate product and bentonite, repefral, diatomite and glass fibre are kneaded, make centre
Inside the interspersed embedded bentonite of macromolecular chain and diatomite in product.Glass fibre can increase whole body in mixing process
The intensity of system.
In other embodiments of the invention, also include producing sulphur and vulcanization accelerator with middle before above-mentioned mixing
Thing is well mixed.
Sulphur and vulcanization accelerator can increase crosslink density, and crosslink density increase can make cross-linked network finer and close,
So that expansion rate of water absorption increases.
In other embodiments, reaction obtains also including mixing dodecyl sodium sulfate and poly- second two before intermediate product
Alcohol.In other words, dodecyl sodium sulfate is mixed with the reactant of above-mentioned cross-linking reaction, dodecyl sodium sulfate is as one
Kind surfactant, can preferably mix each reactant.Increase the mobile performance of reactant.
In the present embodiment, the reaction condition that above-mentioned reaction obtains intermediate product is to be stirred by ultrasonic at 30-40 DEG C.Ultrasound is stirred
Mixing makes whole system mixing more uniform.
In other embodiments of the invention, can according to it is bentonitic using scene or use place will be kneaded after
Material sheared, ground, sieved.Shearing, grinding, sieving obtain high expansion function environmental protection bentonite.Further, grind
Bentonitic water retention property after making water suction to thinner particle is more.
In other embodiments of the invention, also include before above-mentioned mixing：Bentonite is placed in water aquation 2-3 days,
It is subsequently placed at -50~-40 DEG C and freezes 2-3 days, is placed in 90-110 DEG C of environment and dries after being thawed under normal temperature.
Aquation is carried out to bentonite, is freezed, normal temperature unfreezing then drying；The process destroys the aggregation side of bentonite clay particle
Formula, dispersiveness strengthen, and the contact probability increase between particle, the distance between particle and particle reduce, and particularly have viscosity
Fine grain presence, make to form network between particle.Directly contacted between particle, increase Fibre Suspensions when in rub
Wipe power.Internal friction increase, the external force increase that can be resisted.
In addition, the little particle after scattered is more easily entered in the small space between particle and particle, secret room filter cake is formed,
Therefore the volume of filter liquor reduces.The final bentonitic water retention property of increase.
The bentonitic raw material of high expansion function environmental protection provided in an embodiment of the present invention is easy to get, and the utilization rate of raw material is high.Its
The reaction of preparation method is gentle, and reaction condition is not harsh；So energy-conserving and environment-protective in whole preparation process.
