Abstract
The invention discloses a preparation method and an application of a viscous anti-seepage material. The preparation method adopts the following raw materials in part by weight: 0-5 parts of coal ash, 30-60 parts of kaolinite, 40-80 parts of bentonite, 1-3 parts of polyacrylic acid, 0-3 parts of polyacrylamide, 0-3 parts of polyacryl acid ester and 0-2 parts of hexadecyl trimethyl ammonium chloride, the raw materials are fully mixed to obtain the anti-seepage material with the 1.15-1.20 g/cm<3>. The viscous anti-seepage material is mainly used for a 'sandwich'-type anti-seepage system. The invention has the advantages that the anti-seepage performance and the self-recovery function are excellent, the structure is simple, the price is low, the construction is convenient and secondary pollution can not be caused to the environment.
Description
Technical field
The present invention relates to the preparation method of environment protection material, specifically relate to a kind of preparation method and its usage of viscosity impervious material.
Background technology
Along with quickening and the economic rapid growth of Urbanization in China, the generation of municipal wastes, industrial solid wastes and various mines solid waste grows with each passing day.Municipal wastes landfill remains the main disposal of garbage mode of China.In industrial solid wastes and mine solid waste, owing to there being various objectionable constituent (as organic pollutant, heavy metal etc.), landfill is disposed the main disposal options that has become this two classes solid waste.
No matter be city refuse landfill or industrial solid wastes, mine solid wastes landfill site, all need to carry out surface anti-seepage covering and ecological recovery after closing.
Conventional top layer seepage control system is mainly comprised of the thick low density polyethylene rete of 1.0-1.5mm and the thick clay seam of 50cm at present.Because LDPE rete is conventionally by being spliced without the little LDPE film of several piece, both be easily subject to the destruction of stress concentration, also easily by the tree root of Ecosystem restoration system, punctured, whole seepage control system is damaged in the later stage of landfill yard operational process, and be difficult to make up, cause collapse, the percolate of whole landfill yard defense system to increase, environment is caused to secondary pollution.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and a kind of preparation method and its usage of viscosity impervious material is provided, there is the viscosity seepage control system of self-regeneration function.
The object of the invention can realize by following manner: the preparation method of viscosity impervious material, it is raw material that the method be take flyash 0-5 part, kaolin 30-60 part, wilkinite 40-80 part, polyacrylic acid 1-3 part, polyacrylamide 0-3 part, polyacrylic ester 0-3 part and palmityl trimethyl ammonium chloride 0-2 part, with weighing scale, after being fully uniformly mixed, obtain impervious material, density is 1.15-1.20g/cm
3.
The purposes of described viscosity impervious material, mainly make the impervious material of " sandwich " type seepage control system, it forms " sandwich " type seepage prevention by two-layer compacting clay seam and impervious material layer: bottom 10-20cm compacting clay seam, middle 2-3cm impervious material layer, top 10-20cm compacting clay seam, the permeability coefficient 1 * 10 of seepage control system
-10cm/s, for the top antiseepage of various solid wastes landfill sites.
Compared with prior art, tool has the following advantages in the present invention:
(1) two-layer compacting clay seam and impervious material layer form " sandwich " type seepage prevention, permeability coefficient 1 * 10
-10cm/s, has excellent barrier performance.
(2) " sandwich " type seepage prevention has self-regeneration function, and in the situation that perforation appears in top layer clay seam, middle impervious material can stop a leak in water-swelling.
(3) simple in structure, low price, easy construction, can not cause secondary pollution to environment.
Accompanying drawing explanation
Fig. 1 is preparation method's schematic diagram of viscosity impervious material of the present invention.
In figure: 1. top 10-20cm compacting clay seam, 2.2-3cm impervious material layer, 3. bottom 10-20cm compacting clay seam, the 4. waste material layer to be dealt with of landfill.

3.
2 kilograms of 5 kilograms, flyash, 40 kilograms of kaolin, 50 kilograms of wilkinites, 2 kilograms of polyacrylic acid, 2 kilograms of polyacrylamides and palmityl trimethyl ammonium chlorides are raw material, obtain impervious material after being fully uniformly mixed, and density is 1.18g/cm
3.
The purposes of viscosity impervious material, as shown in Figure 1, on the surface of the waste material layer to be dealt with 4 of landfill, lays the thick clay seam of 10-20cm, and clay seam water ratio is 20-23%, comes and goes and rolls compacting three times, obtains bottom compacting clay seam 3; Then lay the impervious material of the present invention 2 of 2-3cm thickness, finally lay the clay seam that 10-20cm is thick, water ratio is 20-23%, comes and goes and rolls compacting three times, obtains top compacting clay seam 1.The permeability coefficient 1 * 10 of this " sandwich " type viscosity seepage control system
-10cm/s.
