Abstract
The invention provides a flexible protective material for a geosynthetic clay liner (GCL), which relates to a material for protecting the GCL. The flexible protective material for the GCL of the invention is prepared by mixing the following materials in percentage by weight: 15% of styrene-acrylate emulsion, 40% of quartz sand, 10% of cement, 3-5% of 107 glue and 30-32% of water, wherein the quartz sand is 200 meshes, and the cement is common cement. The preparation method comprises the following steps: firstly, sieving the quartz sand with a sieve of 200 meshes; weighing each material according to the percentage by weight; uniformly mixing the styrene-acrylate emulsion, the 107 glue and the water; then, adding the quartz sand and stirring; and finally, adding the cement and uniformly stirring for later use. The material has good bonding effect with non-woven fabrics of the GCL, simultaneously can keep the flexible characteristic of the GCL, and has good effect on preventing ultraviolet ray aging. The new protective material of the invention effectively solves the problems. The experimental test proves that the anti-aging performance index of the material of the invention is superior to that of cement mortar.
Description
Technical field
The flexible external protective material of a kind of wilkinite antiseepage blanket relates to a kind of material of protecting wilkinite antiseepage blanket.
Background technology
Wilkinite antiseepage blanket (GCL) is mainly used in municipal garbage landfill yard, highway, industry and covil construction underground waterproof antiseepage construction in the world at present.Be used for the canal seepage control aspect for GCL, it is beyond example geographic particularly to be applied to northern frost zone, and GCL has good anti-seepage effect as the channel novel material of economizing on water, frost heaving resistant is good, compare with the concrete slab lining cutting, operating technique is simple, and operation is few, cost can reduce by 50%, GCL is applied on the canal lining, and external protective material is a gordian technique, directly has influence on GCL work-ing life.Adopt sand-cement slurry as external protective material, weather resistance is relatively poor, after the process frost heave in winter, and easy crack and peeling, and surface finish is poor.
Summary of the invention
The purpose of this invention is to provide a kind of material of protecting wilkinite antiseepage blanket.
15%, 40%, 10%, 3-5%, 30-32% the flexible external protective material of wilkinite antiseepage blanket of the present invention is to be mixed by benzene emulsion, quartz sand, cement, 107 glue and water, and their weight percent is respectively:; Wherein quartz sand is 200 orders, and cement is common.Making method is: earlier quartz sand is crossed 200 mesh sieves, various materials take by weighing weight in proportion, with benzene emulsion, 107 glue and water uniform mixing, put into quartz sand again and stir, and put into cement at last, stir, and can use.
During use, the flexible external protective material of ready-made wilkinite antiseepage blanket uniformly sprayed on wilkinite antiseepage blanket surface get final product.Material characteristics: good with GCL non-woven fabrics bond effect, can keep the GCL flexibility characteristics simultaneously, prevent that ultraviolet ray ageing is effective.This new external protective material efficiently solves the problems referred to above.The process experimental test: this anti ageing property index is better than sand-cement slurry.
Embodiment
Make the flexible external protective material of wilkinite antiseepage blanket of gross weight 100 grams: get benzene emulsion 15 grams, 200 purpose quartz sands, 40 grams, cement 10 grams, 107 glue, 5 grams, water 30 grams; Making method: with benzene emulsion, 107 glue and water uniform mixing, put into quartz sand again and stir, put into cement at last.Stir, can use.
Claims (4)
15%, 40%, 10%, 3-5%, 30-32% 1. the flexible external protective material of a wilkinite antiseepage blanket is characterized in that it is to be mixed by benzene emulsion, quartz sand, cement, 107 glue and water, and their weight percent is respectively:.
2. the flexible external protective material of wilkinite antiseepage blanket according to claim 1, it is characterized in that making method is: earlier quartz sand is crossed 200 mesh sieves, various materials take by weighing weight in proportion, with benzene emulsion, 107 glue and water uniform mixing, putting into quartz sand again stirs, put into cement at last, stirring gets final product.
3. the flexible external protective material of wilkinite antiseepage blanket according to claim 1, quartz sand is 200 orders in it is characterized in that.
4. the flexible external protective material of wilkinite antiseepage blanket according to claim 1 is characterized in that cement is common.
