Embodiment 1

[0069] Put 40 Kg of water-absorbing base, 16Kg of polyacrylamide, and 0.02Kg of additives into a stainless steel reactor, then add 50Kg of water and stir evenly. After 4 minutes, add 20Kg of 200-mesh wheat straw powder and 24Kg of polyacryl alcohol, heat for 10 minutes, and the heating power is 1800W , to get a jelly-like product, then take it out and dry it to get a block-like product. Grinding the bulk product into powder to obtain a powder product.

Embodiment 2

[0071] Put 35 Kg of water-absorbing base, 15Kg of polyacrylamide, and 0.01Kg of additives into a stainless steel reactor, add 40Kg of water and stir evenly. After standing for a while, add 25Kg of 20-mesh corn stalk powder and 25Kg of polyacryl alcohol, and heat for 8 minutes. The heating power is 2kw to obtain a jelly-like product, and then take it out and dry it to obtain the product.

Abstract

The invention discloses a water-absorbing swelling agent and its preparation method and use. The water-absorbing swelling agent solves the problem that the existing water-absorbing swelling agent easily adjusts soil pH to less than 7 so that soil quality deteriorates and a cost is high. The water-absorbing swelling agent comprises, by mass, 4.8-35 wt% of a strengthened base, 10-62.5 wt% of a water-absorbing base, 10-57 wt% of polyacrylamide and 14-37.5 wt% of polypropylene glycol. The water-absorbing swelling agent has a strong water-absorbing capacity of 900 times or more, can fast swell in 3s after contacting with water, has a small use amount less than 1% sand use amount aiming at the same gap, has small density, is easy to carry, can block and seal at any time, realizes easy blocking and reduces flood fighting work intensity and difficulty.

Description

technical field [0001] The invention relates to a water-absorbing swelling agent, a preparation method of the water-absorbing swelling agent and an application thereof. Background technique [0002] There are many rivers in our country, and it is a flood-prone area, especially in summer, the floods 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 usually used in traditional embankment plugging, reinforcement or building height. The sandbags are heavy, inconvenient to carry, and inconvenient to take soil. Therefore, the task of flood fighting and emergency rescue is very tiring and heavy, which is not conducive to the rapid filling of leaks or cracks in flood control dams, which increases the difficulty of flood control. [0003] The Chinese invention patent with the publication number CN1800291, the name "plugging waterproof material" and the application numbe...
