Abstract
The present invention relates to one kind to keep the temperature 12 ~ 18 DEG C of phase change cold accumulating agents for insulin, belongs to biologics field of thermal insulation.The present invention is made after adding hexadecane and expanded graphite mixing homogeneous using phase change paraffin as raw material.Phase change cold-storage agent material prepared by the present invention can be improved ice storage, and phase transition temperature is at 12 ~ 18 DEG C, and for latent heat of phase change up to 260 ~ 290kJ/kg, latent heat of phase change is high, and cold accumulation effects are good；For phase-change material for cold storage prepared by the present invention in flowing shape, viscosity is smaller, is easy to implement industrialized production.
Description
Technical field
The present invention relates to one kind to keep the temperature 12~18 DEG C of phase change cold accumulating agents for insulin, belongs to biologics field of thermal insulation.
Background technique
With the improvement of people ' s living standards, the change of the accelerating rhythm of life and living habit, diabetic's number are in
The trend now risen year by year, while tending to rejuvenation.Especially suffer fromThe patient of patients with type Ⅰ DM, it is necessary to rely on hormone pancreas
Island element carries out blood glucose-control.Insulin belongs to a kind of biological agent, and storage and preservation have stringent environmental condition, do not break a seal
Insulin long-term preservation, the insulin after not breaking a seal or breaking a seal need to can be housed in 2~25 DEG C of temperature under 2~8 DEG C of temperature environments
Spend short-term preservation under environment.The holding conditions of insulin seriously limitThe trip of the patient of patients with type Ⅰ DM.
The refrigerating box for insulin heat preservation occurred currently on the market is by active refrigeration, and soaking time is short, box body
It is heavier, bring trip inconvenient to patient.Therefore, right if can be realized passive refrigeration, long-time cold insulationThe patient of patients with type Ⅰ DM
Trip bring great convenience, for insulin heat preservation cold-storage material will have more vast market prospect.
Summary of the invention
