Preparation method of flood-control and anti-permeable material

Abstract

The invention relates to a preparation method of a flood-control and anti-permeable material. The preparation method comprises the following raw materials in percentage by mass: 70-85% of polyacrylic acid, 12-35% of polyacrylamide, 2.5-10% of bentonite, and 0.5-5% of plant fibers. The material is non-toxic and harmless, fast in water absorption and expansion speed, and the volume can be fast expanded after the material is sunk into water for 3-5 minutes (the weight can be increased by hundreds of times). The material can be used for flood control, fast blocking of loopholes of a dam, heightening of flood control dams, and the like.

Description

technical field [0001] The invention relates to a preparation method of a flood control and anti-seepage material, which is used in the fields of flood control, anti-seepage, building waterproofing and the like. technical background [0002] There are many rivers in our country, and it is a flood-prone area, especially in summer, the floods will cause huge losses to the country and the people. Every year, the country invests a lot of manpower and material resources in flood fighting and rescue. Sandbags are used in traditional embankment plugging, reinforcement or building heights. The sandbag is heavy, and it is more inconvenient to carry, and it is also inconvenient to take soil sometimes. Therefore, the efficiency is low, and the task of flood fighting and emergency rescue is very heavy. [0003] Patent CN1800291 discloses a plugging waterproof material, the plugging waterproof material is composed of 24-60% by weight of Portland cement, 20-63% of high alumina clinker, 0...

AI Technical Summary

Problems solved by technology

Sandbags are heavy, and it is more inconvenient to carry, and sometimes it is also inconvenient to take soil, so the efficiency is low, and the task of flood fighting and rescue engineering is very heavy

[0003] Patent CN1800291 discloses a plugging waterproof material, the plugging waterproof material is composed of 24-60% by weight of Portland cement, 20-63% of high alumina clinker, 0-10% of potassium aluminum sulfate dodecahydrate, di Water gypsum 1-5%, sodium polyacrylate 0-1%, bentonite 2-10%, latex powder 0-2%, quartz sand 10-20%, although it can slow down deep water, but the density is large, the effect is not good, and Inconvenient to carry

[0004] Patent CN1435463 discloses a plugging waterproof material, which is composed of 50-60% β-naphthalenesulfonate sodium formaldehyde high condensation polymer, 10-20% sodium sulfate, and 25-35% high expansion cement, but the density is large, And the effect is not ideal

[0005] Patent CN1600993 discloses a water-absorbing swelling bag and its production method. When the water-absorbing swelling agent in the bag is composed of attapulgite, superabsorbent resin, etc., after encountering water, although the weight and volume will increase and expand, the volume of expansion is limited.
