Further, in table, "-" fitted in subfield represents that this composition does not coordinate.
In addition, "-" in evaluation result hurdle represents that this project is not evaluated.
[table 1]
[table 2]
[table 3]
From the above results, the cold insulation composition of the embodiment 1 ~ 23 of hydroxypropylguar gum (HP guar gum), guar gum or Natvosol (HEC) is employed as tackifier, have nothing to do with the kind of dyestuff, the condensation of tackifier is suppressed, maintains high viscosity.In addition, the viscosity reduced rate of cold insulation composition reduces successively by the order of hydroxypropylguar gum, Natvosol, guar gum, maintains full-bodied effect and raises successively by this order.Such as, from embodiment 4 ~ 12, the content (use level) of tackifier is more, and the condensation inhibition of dyestuff is higher, and when the content of tackifier is more than 0.5 quality %, this effect is high especially.The cold insulation composition of the visible dyestuff condensation as embodiment 4 ~ 5, just cannot see the color change before and after freezing or change very little, be not compromise cold insulation ability, therefore, the cold insulation apparatus possessing this cold insulation composition does not have any obstacle in practicality.But the cold insulation apparatus of the cold insulation composition that the condensation employing dyestuff as shown in embodiment 6 ~ 12 is highly suppressed, it is more preferred range estimation easily identifies this point of the state of cooling.
To this, the cold insulation composition of comparative example 2 and 4 does not all use hydroxypropylguar gum, guar gum and Natvosol, and therefore the condensation of tackifier is remarkable.Although the viscosity reduced rate of these cold insulation compositions is low, can think its reason be because the thermotolerance of tackifier or salt tolerance low, before heat test or from the beginning tackifier just deteriorate, and therefore the viscosity of cold insulation composition reduces.Thus, when container is damaged, can not suppress to the leakage outside container when practical application.On the other hand, the cold insulation composition of comparative example 3 is dissolved in solvent (water) hardly due to tackifier, therefore cannot evaluate the condensation of tackifier and the reduced rate of viscosity.About the cold insulation composition of comparative example 1 ~ 4, the condensation inhibition of its dyestuff is all low, and comparative example 1 confirms that the content of tackifier is more, and the condensation inhibition of dyestuff is higher.
Natvosol is that the hydrogen atom of a part of hydroxyl in Mierocrystalline cellulose is by hydroxyethyl (-CH
2cH
2oH) derivatived cellulose of gained is replaced.In addition, Vltra tears (HPMC) is that the hydrogen atom of a part of hydroxyl in Mierocrystalline cellulose is by hydroxypropyl (-CH
2cH (CH
3) OH) or methyl (-CH
3) displacement gained derivatived cellulose.That is, this point of the derivatived cellulose that the hydrogen atom being a part of hydroxyl Mierocrystalline cellulose from Natvosol and Vltra tears is obtained by hydroxyalkyl Zhi Change, they are similar macromolecular compounds.But from the result of embodiment 3 and comparative example 3, the condensation inhibition of these tackifier in cold insulation composition what can be used as tackifier and completely different according to use.This is when Vltra tears, has methyl as substituent impact, consider that hydroxypropyl and hydroxyethyl are the extremely similar sub stituents that carbonatoms only differs 1 even if exist, and can say it is unexpected completely.
In addition, carboxymethyl cellulose (CMC) is that the hydrogen atom of a part of hydroxyl in Mierocrystalline cellulose is by carboxymethyl (-CH
2cOOH) derivatived cellulose of gained is replaced, replaced by the base jointly had with alkylidene group and hydroxyl (in-C (=O)-OH-OH) from the hydrogen atom being a part of hydroxyl Mierocrystalline cellulose and this point of derivatived cellulose of obtaining, can be described as the macromolecular compound similar with Natvosol.In the embodiment 3 using this similar tackifier and comparative example 2, the condensation inhibition of these tackifier in cold insulation composition is then completely different, can say that this is also very unexpected.
In the tackifier suppressing condensation, their monose of the formation of hydroxypropylguar gum and guar gum is all semi-lactosi and seminose, to this, its monose of the formation of Natvosol is β-glucose, and hydroxypropylguar gum and guar gum are the diverse macromolecular compounds of kind.In the embodiment 1 ~ 3 using these three kinds of tackifier, the condensation inhibition of these tackifier in cold insulation composition all uprises, and completely different from the structure of tackifier it doesn't matter and obtain same result, complete accident.
So, the condensation inhibition of tackifier according to what being used as tackifier with to salt and providing diverse result, can find out common structure very difficult in hydroxypropylguar gum, guar gum and Natvosol.Thus, predict that the combination of the salt that the condensation inhibition of tackifier is high and tackifier can be said very difficult.
Industrial utilizability
The present invention can utilize as the cold insulation apparatus of various fresh thing.
