Abstract

The invention relates to a gel type ice and snow material with adjustable solidification temperature and transmittance and a preparation method thereof, wherein the preparation method comprises the specific steps: firstly, taking an acrylamide polymerization monomer, a cross-linking agent, an initiator, a catalyst, a solidification temperature and transmittance regulator as raw materials to prepare an acrylamide ice and snow material; secondly, taking sodium alginate, a solubilizer, soluble divalent/trivalent metal ion salt, a crosslinking speed regulator, a plasticizer, a gelatinizing agent,a solidification temperature and a light transmittance regulator as raw materials, and carrying out ionic crosslinking to obtain the sodium alginate gel type ice and snow material. By blending the rawmaterial components, the solidification temperature of the gel type ice and snow material can be regulated and controlled within a wide range, and the synthesized material has the characteristics ofgood formability and easiness in processing.
