Abstract
The present invention discloses a water absorption expanding agent and a preparation method thereof. The present invention has the main technical scheme that the water absorption expanding agent is composed of concave-convex rod stone clay, bentonite, anhydrous gypsum and high water absorption resin. Prepared anhydrous gypsum powder, the bentonite and the high water absorption resin are added to concave-convex rod stone clay and are uniformly stirred by a stirrer into a finished product. The water absorption expanding agent of the present invention can be put in bags with different shapes and is widely used for water conservancy construction and building construction during flood fighting, drainage of stagnant water, and risk removal. After the water absorption expanding agent in the bag encounters water, the weight and the volume of the water absorption expanding agent can be increased and expanded by over 10 times and can bear certain pressure. Under the impact of water currents, the bag can not drift, which is favorable to safe and rapid construction. The water absorption expanding agent of the present invention is nontoxic and can not cause environment pollution.
Description
Technical field:
The leak stopping type material that the present invention relates to control flood is specifically related to a kind of water absoption expanding agent and production method thereof.
Background technology:
Speedily carry out rescue work in flood fighting water drainage, in water conservancy and the building operation, leak stopping is the work that generation is often arranged, and in order to improve the ability of leak stopping, in a lot of patent documents, has all done detailed elaboration, has certain effect.From the present water absoption expanding agent of the known leak stopping that is used to control flood, major part is to use High hydrophilous resin merely, and the grail of adding or wood chip are also arranged, and the material of these addings has played certain booster action; But in actual use, though the water-intake rate of High hydrophilous resin is very high, but because High hydrophilous resin suction back density is less, quality is lighter and soft, elastic force is lower, even in leak stoppage bag, added a spot of beans, vegetable fibre, grail or wood chip, after water-swelling, High hydrophilous resin and grail or wood chip etc. can not be evenly distributed, and can not bond mutually, and grail can be deposited in the lower floor of bag, under water impact, leak stoppage bag still can produce drift, is unfavorable for normal construction, and the effect of water absoption expanding agent can not be brought into play preferably.
Summary of the invention:
The objective of the invention is to overcome weak point in the prior art, a kind of water absoption expanding agent and production method thereof are provided, water absoption expanding agent is made up of attapulgite clay 60～85%, wilkinite 5～30%, anhydrous plaster powder 2～20% and High hydrophilous resin 1～15%.
Attapulgite clay is a kind of moisture magnesium alumino metasilicate salt mine, and it has the good adsorption performance, because the inner porous of attapulgite clay road, specific surface area is big, can reach 500m
2More than/the g, most positively charged ion, water molecules and a certain size organic molecule all can directly be adsorbed in the duct, wilkinite suction back volumetric expansion, volume energy expands and increases several times to tens times, dehydrated gyp-also is a kind of swelling agent preferably, and snap cure becomes solid firm object behind the absorption water; Its suction multiple of High hydrophilous resin can reach hundreds of times even thousands of times of own wt.
The present invention is achieved by following technical proposals:
1, select materials:
(1), attapulgite clay and wilkinite, through carrying out airing after the differentiation naturally, moisture should≤10%;
(2), dehydrated gyp-answers inclusion-free, High hydrophilous resin is chosen water absorbent rate according to actual needs, it is better 100～400 times of scopes generally to choose water absorbent rate.
2, batching (weight percent): attapulgite clay 60～85%, wilkinite 5～30%, anhydrous plaster powder 2～20% and High hydrophilous resin 1～15%.
3, oven dry: after attapulgite clay and the wilkinite difference drying, moisture answers≤1%.
4, abrasive dust: carry out abrasive dust respectively with attapulgite clay and wilkinite after the oven dry, go out grinding rate≤0.150mm.
5, stir: anhydrous plaster powder, wilkinite and the High hydrophilous resin for preparing added in the attapulgite clay, and stirring with stirrer is finished product.
6, packing: use the double-layer plastic bag hermetic package.
Water absoption expanding agent of the present invention can be packed in the difform sack, is widely used in that the flood fighting water drainage is speedily carried out rescue work, water conservancy and building operation.After the water absoption expanding agent in the bag runs into water, its weight and volume can increase sharply and expand more than 10 times, because the interaction of attapulgite clay, wilkinite, dehydrated gyp-and High hydrophilous resin, water absoption expanding agent in the bag is evenly distributed and is closely knit, attapulgite clay, wilkinite and dehydrated gyp-also play the skeleton function that supports High hydrophilous resin, therefore can bear certain pressure, under water impact, can not produce drift, help constructing safely and fast.Water absoption expanding agent of the present invention is nontoxic, can not cause environmental pollution.
Embodiment:
The invention will be further described below in conjunction with embodiment,
1, select materials:
(1), attapulgite clay and wilkinite, through carrying out airing after the differentiation naturally, moisture should≤10%;
(2), dehydrated gyp-answers inclusion-free, selecting water absorbent rate for use is 200 times High hydrophilous resin.
2, batching (weight percent): attapulgite clay 70%, wilkinite 20%, anhydrous plaster powder 5% and High hydrophilous resin 5%.
3, oven dry: after attapulgite clay and the wilkinite difference drying, moisture answers≤1%.
4, abrasive dust: carry out abrasive dust respectively with attapulgite clay and wilkinite after the oven dry, go out grinding rate≤0.150mm.
5, stir: anhydrous plaster powder, wilkinite and the High hydrophilous resin for preparing added in the attapulgite clay, and stirring with stirrer is finished product.
6, packing: use the double-layer plastic bag hermetic package.
Claims (1)
1, a kind of production method of water absoption expanding agent is characterized in that, the production method of water absoption expanding agent is that anhydrous plaster powder, wilkinite and the High hydrophilous resin that will prepare adds in the attapulgite clay, and stirring with stirrer is finished product; The batching of water absoption expanding agent is calculated by weight percentage: attapulgite clay 60～85%, wilkinite 5～30%, dehydrated gyp-2～20% and High hydrophilous resin 1～15%.
