Abstract
The environment protection anti-seeping agent is used mainly for anti-seepage in roofing and water conservancy engineering. It is prepared by mixing modified polysodium acrylate with at least one of cement, quartzite, fuel coal slag and stone powder. It has high antiseeping effect, low production cost, simple application process, no toxicity and no pollution, and the utilization of waste materials is favorable to environment protection.
Description
The invention provides a kind of loss circulation material, be mainly used in antiseepage leakproofs such as roof, hydro project.
At present, the antiseepage of roof is handled and is generally adopted materials such as pitch, malthoid to carry out.This method cost height, working life is short, generally about 3～5 years.And construction technology complexity.Existing hydro project is adopted materials such as building stones, cement as the antiseepage of reservoir, He Ba, bank protection etc. is handled, not only involve great expense, and the antiseepage leak preventing effect is also relatively poor.
The purpose of this invention is to provide a kind of environment protection anti-seeping agent,, reduce production costs to improve its working life.
The present invention realizes like this, environment protection anti-seeping agent, by at least a the mixing in four kinds of materials such as modified polyacrylic acid sodium and cement, quartz sand, coal-fired slag, stone flour, its proportioning is modified polyacrylic acid sodium by weight: at least a=1: 7～25 in cement, quartz sand, coal-fired slag, the stone flour.
This loss circulation material good seepage-proof property.During use, it is tiled on pending, thickness is about 1-2 centimetre.After meeting water, water can only infiltrate the very thin one deck on the material layer upper strata that this loss circulation material makes, good leak-proof effect.Production cost is low, only prevents about half of drain process for malthoid.Working life is long, can reach about 10 years.Through destructive test, this loss circulation material all can normally use in-30 ℃～+ 120 ℃ scopes.Nontoxic, harmless, pollution-free, and utilized various wastes, the waste when especially it can make full use of this coal mining of coal gangue has avoided it to stack all the year round on the ground, constantly spontaneous combustion, dust formation and pollution on the environment, and environmental protection effect is remarkable.
Further specify the present invention below.
Raw materials such as described modified polyacrylic acid sodium and cement, quartz sand, coal-fired slag, stone flour should be crushed to 50～150 orders.And then carry out thorough mixing.
Modified polyacrylic acid sodium is when in cement, quartz sand, coal-fired slag, the stone flour two or more mixes, and the blending ratio between cement, quartz sand, coal-fired slag, the stone flour can choose at random, no particular requirement.
Described stone flour is the depleted stone dust that produces of stone dust such as building stones field, colliery powder etc.
Below be embodiments of the invention and assay.
Embodiment 1:
With ball mill with various raw material pulverizing to 130 orders, carry out thorough mixing with mixing machine then, raw material that adopts during mixing and proportioning are modified polyacrylic acid sodium: cement: quartz sand by weight: coal-fired slag: stone flour=1: 3: 1: 2: 2, make environment protection anti-seeping agent.
Embodiment 2:
With various raw material pulverizing to 140 orders, carry out thorough mixing with mixing machine with ball mill then, raw material that adopts during mixing and proportioning are modified polyacrylic acid sodium: cement by weight: coal-fired slag=1: 8: 9, make environment protection anti-seeping agent.
Embodiment 3:
With various raw material pulverizing to 120 orders, carry out thorough mixing with mixing machine with ball mill then, raw material that adopts during mixing and proportioning are modified polyacrylic acid sodium by weight: stone flour=1: 23, make environment protection anti-seeping agent.
Below be the service check result of the present invention's environment protection anti-seeping agent.
| Test item | Performance requriements | Test-results | The individual event evaluation |
| Outward appearance (solid-state) | Grey or white powder | The conformance with standard requirement | Qualified |
| Outward appearance (liquid state) | Be thick | ?/ | ?/ |
