Abstract
The invention relates to a snow melting deicing agent and a preparation method thereof, particularly relates to a biodegradation type snow melting deicing agent and a preparation method thereof, and belongs to the technical field of chemistry. The biodegradation type snow melting deicing agent comprises the following components in percentage by weight: 20%-60% of freezing point reducing agent, 1%-8% of ice lattice breaking agent, 2%-5% of anti-ice adhesive, 0.05%-2% of thickener, 0.05%-5% of surface active agent and the balance of solvent. The biodegradation type snow melting deicing agent has strong snow melting deicing capacity and extremely small corrosivity on metals and concrete. Importantly, the biodegradation type snow melting deicing agent is easy to biologically degrade and almost harmless to human bodies, animals, plants and microorganisms and is a full biodegradation type snow melting agent which can be used for rapidly melting ice and snow.
Description
Technical field
The present invention relates to a kind of deicing or snow melting agent and preparation method thereof, especially a kind of biodegradation type deicing or snow melting agent and preparation method thereof, belongs to technical field of chemistry.
Background technology
At China and the extremely frigid zones of many countries in the world, winter, ice and snow became serious public hazards, deep accumulated snow and smooth road surface, caused traffic jam, accident repeatedly, motorway stops transport, the serious consequences such as socked-in.Generally adopt the mode of the surface sprinkling deicing or snow melting agent after snow to reach deicing or snow melting effect.The exploitation of deicing or snow melting agent has been experienced single salt type, inorganic villaumite type to organic type, anticorrosion type.But the Snow Agent of the above-mentioned type, cannot be degradable, and environment is had to certain harm.
Summary of the invention
The technical problem to be solved in the present invention is the defect existing for prior art, proposes a kind of biodegradation type deicing or snow melting agent and preparation method thereof, can reach complete biodegradable, and environment zero is endangered.
The present invention is technical solution problem by the following technical programs: the agent of biodegradation type deicing or snow melting, and the component that contains following weight percent:
In said components, described in to fall freezing point agent be ethylene glycol or propylene glycol.
Described ice crystal lattice disrupting agent is polyether-modified heptamethyltrisiloxane or 1,2-bis-(triethoxy is silica-based) ethane.
Described anti-ice adhesive agent is 2,6,10,14-tetramethyl-pentadecane, squalene, 2,6,10,15,19, the one in 23-squalane.
Described thickening material is the one in starch, xanthan gum, Mierocrystalline cellulose.
Described tensio-active agent is the one in cholesterol, tea saponin, alkylglycoside.
Described solvent is methyl alcohol or ethanol.
The present invention further provides the preparation method of biodegradation type deicing or snow melting agent, each raw material is taken in described ratio, for subsequent use, in reaction vessel, add solvent, after whipping appts in unlatching reaction vessel, add and fall freezing point agent, add again ice crystal lattice disrupting agent, being stirred to ice crystal lattice disrupting agent is dispersed in solution, add anti-ice adhesive agent, be stirred to after anti-ice adhesive agent dissolves and add tensio-active agent, be stirred to after tensio-active agent is uniformly dispersed in solution and add thickening material, be stirred to thickening material and be uniformly dispersed in solution, be finished product.
Biodegradation type deicing or snow melting of the present invention agent, not only deicing or snow melting ability is strong, and minimum to metal, concrete erosion.Importantly Snow Agent of the present invention is easily biodegradable, almost harmless to human body, animals and plants and microorganism, is a kind of all biological degradation type Snow Agent that can thaw ice and snow fast.
