Embodiment Construction

[0036] Below in conjunction with embodiment the present invention will be further described:

[0037] The production method of the attapulgite environment-friendly deicing agent is characterized in that (1) the ingredients of the attapulgite mixture are input into a mixer for stirring, and after stirring evenly, they are added to the soaking pool; (2) the diluted glacial acetic acid is slowly added to the unevenness in the soaking pool. Carry out acidification treatment in the rod mixture, and the acidification time is controlled at 36 hours; (3) input the acidified attapulgite rod mixture into an extruder to be extruded into a sheet, and the thickness of the sheet is ≤3 mm; (4) The flakes are transported to the drum dryer for slow drying, the drying time is 4 hours, and the drying temperature is controlled at 65-75°C; (5) The dried flakes are input into the pulverizer for crushing and sieving, and the particles The fineness is controlled at 0.25-5 mm, the water content is ≤1....

Abstract

The invention discloses a production method of an attapulgite environmental-friendly snow melt agent, which comprises the steps of preparing materials, stirring, acidizing, extruding, drying, crushing, screening, mixing and packaging into finished products. The attapulgite environmental-friendly snow melt agent comprises attapulgite clay, bentonite, ground limestone, glacial acetic acid, quicklime, granular activated attapulgite clay, super water absorbent resin, super oil absorbent resin, lauryl sodium sulfate and water. The attapulgite environmental-friendly snow melt agent is an irregular granular mixture, can rapidly melt ice and snow, effectively prevents the melted snow or ice from being frozen again, improves the snow melting effect, can absorb harmful substances and oil stains mixed into gel matters, and greatly reduces the pollution after the ice and the snow are melted. The production method of the attapulgite environmental-friendly snow melt agent is suitable for producing various environmental-friendly snow melt agents.

Description

technical field [0001] The invention relates to a deicing agent, in particular to a production method of an attapulgite environment-friendly deicing agent. Background technique [0002] Snow melting agent, also known as deicing salt and road antifreeze, is a snow removal substance widely used in winter. agent. [0003] "Chloride salt" deicing agents are better for snow melting and antifreeze, and the price is also cheap. After the ice or snow melts into liquid, its salt residues will accumulate in farmland and green belts, which will cause damage to crops and green plants. A large number of deaths will shorten the life of the road. The chemical reaction between the salt and the asphalt will cause the asphalt surface to fall off, and the road surface will be damaged under the action of the driving load. One of the important factors, it seriously threatens the safety of industrial facilities. After "chlorine salt" substances enter the ground, they will also pollute the loca...
