The cold preserving agent is ice free at a temperature of -20 DEG C and has long cold preserving time more than 4h, and can be prepared at a normal temperature. The invention has better effect on the aspects of medicinal cold treatment, family health and the like.
Description
Technical field
The present invention relates to a kind of cold-retaining agent and preparation method thereof, especially a kind ofly can prepare at normal temperatures and have cold-retaining agent of long-time cold insulation effect and preparation method thereof.
Background technology
At present, Physical temperature-lowering in medical science or family health care is processed the ice bag that is mostly of use, ice bag in use dispels the heat comparatively fast, and be not suitable for the elderly and infirm and use, storage needs freezing environment, produces and need to expend time in, when cold treatment owing to being solid, lack flexibility, can not accomplish that maximum area contacts with skin, comfort level is poor.The cold-retaining agent of other type exists mostly also that similar preparation is complicated, the storage environment is strict, the shortcomings such as freezing point temperature is low, rewarming time short (common 1～2 hour).
Summary of the invention
Thus, the invention provides the cold-retaining agent that a kind of preparation method's simple and fast, freezing point temperature are low, rewarming time is long.
The present invention is achieved through the following technical solutions:
The present invention relates to a kind of cold-retaining agent, it is characterized in that: comprising: wilkinite, polyacrylate, glycerine, dehydrated alcohol, water, salt, styrene-butadiene emulsion and bamboo charcoal powder.
Wherein, glycerine and dehydrated alcohol can be substituted by polyvinyl alcohol and ethylene glycol respectively.
Cold-retaining agent of the present invention prepares simple and fast, just can carry out under normal temperature; Do not freeze when-20 spend, freezing point temperature is low; Cold insulation is stored at shady and cool environment and gets final product for up to more than 4 hours; Have flexibility, can accomplish that maximum area contacts with skin during use, and to human body constitution without strict demand.Can be applicable to easily the Medical cold therapies such as wound cold compress, fever is reduced phlegm and internal heat, body part is cooling and family health care aspect.
Embodiment
The present invention will be described in more detail below.
Cold-retaining agent main component of the present invention comprises: wilkinite, polyacrylate, glycerine, dehydrated alcohol, water, salt, styrene-butadiene emulsion, bamboo charcoal powder.In mass parts, the proportioning of each component can be wilkinite 150～250 mass parts, polyacrylate 700～1000 mass parts, glycerine 350～450 mass parts, dehydrated alcohol 350～450 mass parts, water are 900～1200 mass parts, and salt is 50～150 mass parts; styrene-butadiene emulsion 350～450 mass parts, bamboo charcoal powder 50～150 mass parts.
Preferably, the ratio of each component is: wilkinite 170～200 mass parts, polyacrylate 750～850 mass parts, glycerine 400～450 mass parts, dehydrated alcohol 400～450 mass parts, water are 950～1000 mass parts, and salt is 80～120 mass parts; styrene-butadiene emulsion 380～420 mass parts, bamboo charcoal powder 80～120 mass parts.
Above-mentioned wilkinite can be common medical wilkinite, and its granularity is preferably 80～150 orders, more preferably 100～120 orders.
The granularity of above-mentioned bamboo charcoal powder is preferably 80～150 orders, more preferably 100～120 orders.Bamboo charcoal powder can produce far infrared rays, and the most suitable absorption of human body of wavelength can make human body produce low-grade fever, promotes the metabolism of human body, accelerates blood circulation, improves histocyte nutrition, improves the human internal environment.
Above-mentioned styrene-butadiene emulsion can be the styrene-butadiene emulsion of common market sale, and its concentration is preferably 35～45wt%, preferred 40wt%.
Cold-retaining agent of the present invention can not freeze when-20 spend.
In addition, the glycerine in the present invention and dehydrated alcohol can be substituted by polyvinyl alcohol and ethylene glycol respectively, and the proportioning separately after substituting is with replacement is front not identical.
Cold-retaining agent of the present invention can be produced simply by following method, the method comprise the steps: at normal temperatures the wilkinite water is moistening after, be stirred to evenly; Then with the polyacrylate salts of dilute with water with wetting after wilkinite mix; Then add glycerine, dehydrated alcohol, and the salt solution of dilute with water; Continue to stir, after forming pasty state, add styrene-butadiene emulsion; Add at last bamboo charcoal powder.
The present invention is described by the following examples.The invention is not restricted to following embodiment, can change in the scope that the present invention requires.
