Abstract
The invention relates to a preparation method of a granular-type waterproof leakproof material by using coal and oil shale. The preparation method comprises the following steps of: mixing coal containing oil shale with a normal-temperature liquid-state polycarbonic alkane organic matter according to a certain proportion, stirring and drying. According to the preparation method disclosed by the invention, high-efficiency utilization of coal resources is realized and particularly relates to the contents of the coal, the oil shale and the normal-temperature liquid-state polycarbonic alkane organic matter in a composition. The invention also relates to the granular-type waterproof leakproof coiled material which is prepared by adopting the following step of: coating the granular-type waterproof leakproof material onto special spun geotextile through glue, wherein the coating thickness of the granular-type waterproof leakproof material is determined according to engineering demands.
Description
One, technical field
The present invention relates to the waterproof and antiseepage preparation methods; Granule type waterproof and antiseepage preparation methods is the liquid many alkyl chain length organism of the coal that contains resinous shale and normal temperature to be mixed by a certain percentage stir drying and form; Be particularly related to coal in the compsn, resinous shale and the organic content of normal temperature liquid alkyl, relate to a kind of preparation method of granule type waterproof and antiseepage coiled material
Two, background technology
Known coal and resinous shale contain a large amount of carbon atoms, and carbon atom can adsorption zone carbonium and molecule through covalent linkage and ionic linkage mode, can inlay in the appearance of carbon atom just having/ion of negative charge, like hydrogen ion.The organic peripheral ion of liquid many alkyl chain length is a hydrogen ion, and H-O-H has repulsive interaction with water molecules, and is therefore water insoluble, be mounted to the carbon granule surface after, make carbon granule have the effect of repelling water molecules.Therefore the liquid alkyl organism is embedded in the surface of carbon granule, just can reaches the purpose that carbon granule repels water molecules, form the particulate state impervious material.Known carbon nuclei hydrogen ion adsorption principle is following:
Surface chemistry absorption
Many decolorizing carbon can be regarded as by mixed and disorderly pile up of graphite linings and form, and graphite can form the compound of a series of uniquenesses, is called graphite compound.Many graphite compounds are to fill compound between interlayer, and majority is nonstoichiometry, and the character of key has very big variation according to the bonded material.[" each opinion of inorganic chemistry " Shanghai education publishing house; Seminar on Chemistry the 15th 69 pages of volume author's residential district sun one (this day), chapter 5; The 4th family's typical element, first segment carbon] coal and oil shale particle belong to decolorizing carbon is the mixture of staple, and it has the essential characteristic of graphite compound, can form complicated chemical bond with multiple material; Particularly there is a large amount of graphite mould interlayer gaps in the coal particles surface, and the surface has negative charge nC
-Utilize the nCH of liquid alkyl compound molecule under the normal temperature based on this
+With nC
-The complexing attribute; Can coal and oil shale particle the surface generate a large amount of C-H-C ion covalent linkage; Reach the purpose of inlaying alkylate at coal and oil shale particle surface by utilizing chemical bond; Form the decolorizing carbon particle that the surface is surrounded by alkyl, these particles have repellency, and the drinking water ability of unit surface can be weighed with the Van der Waals force of contained alkyl organic molecule.
Test shows; Coal and oil shale particle particle surface and alkyl organic cpds be adsorbed as molecular adsorption; The concrete inherent mode and the bonding force of these two kinds of absorption still await further research, and most possible is that intermolecular Van der Waals force is the main reactive force of this absorption.With the repellency is main impervious material, and the material that is difficult for airtight antiseepage has self-defence ability more trusty on microcosmic.
The proposition of technical problem:
How to solve the dough deformation that common waterproof, seepage control material has under natural temperature ability, solve material stress change break, hidden leakage defect and environmental hazard that weather aging, temperature deformation, freeze thawing deformation bring?
Conventional way:
Use blocky waterproof, seepage control coiled material and plastic cloth, malthoid, bituminous coating etc. as far as possible.
Three, summary of the invention
The present invention utilizes that hydrophilic coal and oil shale particle and normal temperature liquid alkyl organic cpds full and uniformly mix, chemical combination forms the particle matter with good repellency, realizes the surface-treated of coal particles through oven dry.Adopt normal temperature liquid alkyl organic cpds; Can reduce production energy consumption and cost; Do not reduce the repellency effect; See that these particles are deployed to layer position that needs antiseep according to requirement of engineering by different thickness, just formed the flexible barrier function under the complex environments such as adapting to freeze thawing deformation, the change of stress property, temperature difference deformation within the specific limits, solve the impervious material safety-problems under the complex environment.
Implement the basis:
Coal and oil shale particle can be pulverized through coal and make varigrained product; Can use after the drying; Normal temperature liquid alkyl organic cpds for example lipid acid, liquid paraffin, alkyl-silicone oil etc. is the chemical product that routinizes, and both mixing stir at normal temperatures and get final product.
The object of the invention:
A kind of low cost, high-performance are provided, adapt to the preparation method of a kind of granule type waterproof and antiseepage coiled material that under complex environment, uses.
Preparing method of the present invention is:
1, select bigger coal and the resinous shale of density, density can improve the particulate compressive strength greatly;
The weight of 2, weighing dry weight PM for particulate matter and normal temperature liquid alkyl organic cpds;
3, according to the blending ratio of design, mixing and stirring gets final product.
4, dispose solid and alkyl organic compound compositions according to the above ratio; Wherein the gross weight of coal particles accounts for the 1-98% of composition total weight per-cent; The gross weight of resinous shale accounts for the 1-98% of composition total weight per-cent, and the gross weight of normal temperature liquid alkyl organic cpds accounts for the 1-98% of composition total weight per-cent.
Four, embodiment
Below in conjunction with case study on implementation the present invention is further described.
1, calculates by producing 1 ton of particle impervious material, need 400 kilograms hard coal particles and 450 kilograms resinous shale and 50 kilograms liquid alkyl organic cpds.
2, aforementioned proportion is disposed raw material, mixing and stirring in stirred pot obtains the waterproof and antiseepage particle, places ageing in 72 hours reaction, obtains qualified waterproof and antiseepage particle.
Waterproof and antiseepage particle by above method is produced is effective, and at the bottom of the cost, suitability is strong, utilizes this scope wide, guarantees reducing cost of seepage control project, improves the security of seepage control project.
3, granule type waterproof and antiseepage material is overlayed on the special-purpose geotechnological woven through glue cloth, the thickness that granule type waterproof and antiseepage web of material is covered is decided according to requirement of engineering, is prepared into granule type waterproof and antiseepage coiled material.Granule type waterproof and antiseepage coiled material can be applied to construction work, afforestation project, hydro project widely and relate in the Other Engineering that needs waterproof and antiseepage.
