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.

Description

technical field [0001] The invention relates to the field of preparation and processing of new materials, in particular to a gel-type ice and snow material with adjustable solidification temperature and light transmittance and a preparation method. Background technique [0002] The crystal clear ice and the whiteness and moistness of the snow give the ice and snow culture a unique charm, making people fascinated by the colorful world of ice and snow. However, the life of ice and snow works such as ice sculptures and snow sculptures is short and fragile, because the increase in ambient temperature will cause ice and snow to melt into water, lose their original structure and shape, and cannot be preserved for a long time. At the same time, the poor formability and processability of ice and snow make it impossible to become a processed material, such as decorations, souvenirs, ornamentals, toys, etc., which has become a huge obstacle to the close integration of ice and snow wit...
