Problems solved by technology

[0005] The technical problem mainly solved by the present invention is that the leachate regulating pool in the landfill currently mainly adopts reinforced concrete pool and geomembrane anti-seepage pool structure, and the geomembrane such as high-density polyethylene in the anti-seepage material has low strength and is puncture-resistant Poor ability, acid and alkali leachate is easy to corrode the defects of reinforced concrete structure, providing a preparation method of acid and alkali resistant puncture and anti seepage material

Embodiment Construction

[0023]In parts by weight, mix 60-70 parts of polystyrene and 30-40 parts of vinyl acetate resin to obtain a mixed resin, pour the mixed resin into a three-necked flask containing 60-70 parts of styrene, and heat the three-necked flask Raise the temperature to 80-90°C, start the agitator, stir and disperse at a speed of 300-350r / min, keep warm and stir for 4-5 hours, discharge the material, naturally cool down to room temperature to obtain polyester glue, and set aside; Aluminum hydroxide powder Put it in a high-pressure airflow machine, and pulverize it by airflow for 10-15 minutes to obtain superfine aluminum hydroxide powder with a particle size of 50-80 μm. Pour 200-220 g of superfine aluminum hydroxide powder into In a beaker of sodium silicate solution, the mixed solution is obtained, and the mixed solution is placed in a high-speed disperser at a speed of 3000-3300r / min to disperse at a high speed to obtain a dispersion glue; in parts by weight, 20-25 parts of E-51 Epoxy...

Abstract

The invention discloses a preparation method of an acid and alkali resistant anti-puncture anti-seepage material, and belongs to the technical field of preparation of environmental protection materials. Since fumed silica particles have large surface defects, many unpaired atoms and high surface activity, a large interfacial effect is generated on the surface of double-layered glass wool, and thefumed silica is dispersed in the gap of a polyester molecular chain, so that the elasticity of polyester resin and a fumed silica system is improved and resistant to plant root tip puncture. Quick lime reacts with water to form calcium hydroxide that reacts with sulfate in the manganese residue to form unite particles in the anti-seepage material. The heavy metal ions in the clay slurry componentmanganese slag are mostly in the form of sulfate, and the heavy metal ions of a landfill can be in complexing with modified polyester, hydrated silicate is insoluble under alkaline conditions, a claylayer in the anti-seepage material can be used as a protective film to make the clay slurry have acid and alkali resistance, so that the material has broad application prospects.

Description

technical field [0001] The invention discloses a preparation method of an acid and alkali resistant puncture and seepage-proof material, which belongs to the technical field of preparation of environmental protection materials. Background technique [0002] Anti-seepage material is a functional material that prevents liquid substances or gaseous (such as water vapor) substances from intruding into the protective structure. It has an anti-penetration effect that cannot be compared with ordinary waterproof materials. The vapor permeability coefficient can reach 10-12cm / s, so the material is almost impermeable to water. Currently, commercially available anti-seepage materials include polyvinyl chloride geotechnical materials, high-density polyethylene geotechnical materials, linear low-density polyethylene geotechnical materials, etc. It can be applied in fields such as highway soft foundation reinforcement. With the acceleration of my country's urbanization process and rapid...
