Attapulgite snow-melting agent for pavement, and preparation method of attapulgite snow-melting agent

Abstract

The invention discloses an attapulgite snow-melting agent for a pavement, and a preparation method of the attapulgite snow-melting agent. The attapulgite snow-melting agent is prepared from the following components: modified attapulgite clay, granular activated attapulgite clay, activated carbon, microporous calcium carbonate, sodium chloride, calcium chloride, limestone, plant ash, polyacrylamide, potassium acetate and sodium gluconate. The preparation method comprises the steps: firstly, preparing the modified attapulgite clay and the granular activated attapulgite clay; respectively weighing the modified attapulgite clay, the granular activated attapulgite clay, the activated carbon, the microporous calcium carbonate, the calcium chloride, the potassium acetate, the sodium gluconate and a right amount of water, and carrying out ultrasonic dispersion; then, adding the plant ash, mixing and drying; mixing the dried mixture with the limestone and the polyacrylamide, and fully and evenly stirring. The attapulgite snow-melting agent is applied to roads with snow and ice, not only has better deicing and snow-melting effects, but also can effectively remove ice water and oil stain on the road surfaces, and improves the road safety, thus having better use value.

Description

technical field [0001] The invention relates to the field of attapulgite technology, in particular to an attapulgite deicing agent for road surfaces and a preparation method thereof. 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] Using the existing ice-melting and snow-melting agent, the speed of ice-melting and snow-melting is slow, and after the ice or snow melts into liquid, it is easy to freeze again, and the sewage without freezing will flow into the low-lying places on the road surface, farmland, green belts and rivers , collection processing cannot be performed. And the freezing and snow on the road have seriously affected the normal driving of various vehicles. Frequent starting of vehicles often causes oil leakage from the engine and chassis. After the oil and snow are mixed together, it is difficult to separate oil from water, increasing The inte...

[0003] Using the existing ice-melting and snow-melting agent, the speed of ice-melting and snow-melting is slow, and after the ice or snow melts into liquid, it is easy to freeze again, and the sewage without freezing will flow into the low-lying places on the road surface, farmland, green belts and rivers , unable to collect and process

And the freezing and snow on the road have seriously affected the normal driving of various vehicles. Frequent starting of vehicles often causes oil leakage from the engine and chassis. After the oil and snow are mixed together, it is difficult to separate oil from water, increasing The intensity of pollution has increased, posing a great threat to the human environment and human life.
