Abstract
The present invention relates to an ice pad which is mainly composed of a flexible bag 1 and heat storage materials sealed in the flexible bag, wherein the heat storage materials are formed by mixing the following materials: plyacrylic acid, 35% to 70% of mixtures of polyvinyl alcohol or propanetriol and propanediol, anticorrosion agents, solvents and water. Compared with the prior art, the present invention has the advantages of low solidifying point and molded and stable shape.
Description
The present invention relates to a kind of health product that helps body temperature lowering or intensification, particularly a kind of ice pad.
Existing ice pad generally is that the fill heat accumulating forms in a soft bag, and the freezing point of used heat accumulating (as water) all about 0 ℃, during use, will be iced pad earlier and put into refrigerator a period of time, just take out use when the ice pad cools to desirable value.This ice pad since freezing point all about 0 ℃, after placing ambient temperature to be lower than its freezing point temperature certain hour, the ice pad will become very hard because of heat accumulating solidifies, can not change in response to the difference of body shape, thereby limited the scope of application of ice pad, in addition, though existing ice pad can change its shape according to actual needs when non-curdled appearance, but because heat accumulating is mobile strong, shape after the change is difficult for firmly getting off, variation because of gravity or present position changes easily, has influenced the effective utilization of ice pad.
Goal of the invention of the present invention be to provide a kind of can be at the ice pad that temperature lower below 0 ℃ can not solidified, shape is plastic and stable.
The present invention is achieved in that and comprises soft bag and be sealed in the interior heat accumulating of soft bag that wherein heat accumulating is to be formed by following material mixing:
Polyacrylic acid, consumption account for the polyvinyl alcohol of 35%-70% or mixture, antiseptic, solvent, the water of glycerol and propylene glycol.
Polyacrylic effect is to make mixture be gel, make ice pad both plastic and mould after shape be difficult for changing.
The effect of the mixture of polyvinyl alcohol or glycerol and propylene glycol is the freezing point temperature of control heat accumulating, and along with the increasing of consumption, the freezing point of heat accumulating descends.
The effect of antiseptic is to prevent from that antibacterial from multiplying to make heat accumulating rotten in heat accumulating, finally causes
The ice pad lost efficacy.
The effect of solvent, water is that the above-mentioned material dissolving is made their mix homogeneously.
The present invention also can help human body to heat up except helping the body temperature lowering, promptly will ice pad earlier and place hot water a period of time, takes out then and apply on human body to get final product.
Compared with the prior art the present invention had both had the low advantage of freezing point, also had the plastic and stable advantage of shape simultaneously.
Fig. 1 is a structural representation of the present invention.
Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail:
The present invention is achieved in that mainly and is made of soft bag 1 and the heat accumulating 2 that is sealed in the soft bag 1 that wherein heat accumulating is to be formed by following material mixing:
Polyacrylic acid, consumption account for the polyvinyl alcohol of 35%-70% or mixture, antiseptic, solvent, the water of glycerol and propylene glycol.
Here, molecular weight is that the polyacrylic consumption of 250-350 ten thousand is 1.0%-1.4%; Molecular weight is that the consumption of 1: 1 mixture of the polyvinyl alcohol of 1400-1800 or glycerol and propylene glycol is 35-45%; The consumption of at least two kinds the antiseptic that mixture constituted in methyl hydroxybenzoate, ethyl hydroxybenzoate, the propyl hydroxybenzoate is 0.09%-0.13%; The consumption of alcohol solvent is 0.9-1.1%; Other be water.Like this, the freezing point of the heat accumulating of made ice pad about-10 ℃, and the shape of ice pad plastic and mould after dimensionally stable.
Claims (1)
1, a kind of ice pad comprises soft bag and is sealed in the interior heat accumulating of soft bag, and heat accumulating is formed by following material mixing:
