Description
Technical field
The present invention relates to a kind of spontaneous heating body.
Background technology
Spontaneous heating body, it is warming patch（It is commonly called as " warm patch ", " warmer ", " a patch heat ", " warmer shellfish " etc.）It is to be used for human body
Warming product critical material, its general principle are：By the formula in appropriate proportions such as iron powder, powdered carbon, vermiculite, resin, salt
Heater is made in mixing, is loaded into and is covered with microporosity oxygen permeation membrane in the sack that non-woven fabrics is made, outside the plastics of external application oxygen barrier
Bag packaging.In use, tearing plastic outer bag, after non-woven fabrics inner bag ingress of air, oxygen enters from the micropore of non-woven fabrics, and and iron
Oxidation reaction occurs for powder, so as to produce heat, reaches effect of keeping warm.Warming patch product heating temp is generally 40 in the market
DEG C~65 DEG C, hold time 10 hours or so.
Some significantly deficiency be present in existing product：（1）Heater is too thick, and volume is big, during for human body warm very unsightly；
（2）It is packed powdered substance, it is easy to the material leakage caused by breakage, so as to cause the pollution to human body or clothing to damage；（3）Hair
Hot temperature is unstable, and it is easily to cause low temperature to be scalded to cause scald sympathetic sometimes.
The content of the invention
It is an object of the invention to provide a kind of sheet type spontaneous heating body and its preparation method and application, to overcome prior art
Existing drawbacks described above.
The sheet type spontaneous heating body of the present invention, include the component of following percentage by weight：
Preferably, sheet type spontaneous heating body, the component of following percentage by weight is included：
The thickness of the sheet type spontaneous heating body is 1mm-4mm；
The molecular weight of described superhigh molecular weight polyethylene fibers is 1 × 106~3 × 108；
The preparation method of the present invention, comprises the following steps：By xanthans, Arabic gum or carboxymethyl cellulose（CMC）, work
Industry salt, NP-4 and water mix at normal temperatures, obtain pastel, stand 10 hours；
The addition weight of water is 10-15 times of xanthans, Arabic gum or carboxymethyl cellulose weight；
Under normal temperature, iron powder, activated carbon superhigh molecular weight polyethylene fibers are added, is stirred, is compressed into tablet form or needs
Three-dimensional shape, then under more than 720 support vacuums, 180 DEG C of dryings 1.5 hours, you can obtain described sheet type spontaneous heating
Body.
The water of formula ratio adds when in use.
The present invention so uses：
After adding the water of formula ratio, loading claims " inner bag " after being covered with microporosity oxygen permeation membrane in the sack that non-woven fabrics makes,
It is outer to be packed with the plastic outer bag of oxygen barrier.In use, tear plastic outer bag, after non-woven fabrics inner bag ingress of air, oxygen is from non-woven fabrics
Micropore enter, so as to produce heat, reach effect of keeping warm.
The new composition of raw materials of the present invention produces chemical reaction heat, considerably improves the heating temp stability of spontaneous heating body；
At the same time, reach the same time with less raw material, thick and heavy heater is not required to so as to solve；Fried batter in a thin layer by special processes
Shape heater, so as to it is more attractive, without material leakage problem, safer.The sheet type heater that the technology of the present invention is made, it is ultra-thin, be easy to
Moulding, heating are stablized, without material leakage, safer environmental protection, can be widely applied to human body warm patch, medical operation Warm cover, medical treatment guarantor
It is strong to alleviate dysmenorrhea plaster, breast health-care, the health care of lumbar vertebrae strength vertebra disease, instrument and meter and number with patch heating and thermal insulation, female menstrual period
Code many fields such as product Portable heating is warming.
