Abstract
A self-heating agent is prepared from iron powder, pearlite, floating bead, activated carbon, sodium chloride and water and features less corrosion. The warming bag made up of said self-heating agent features long warming time, stable temp.
Description
The present invention involves a kind of self-generating exothermal agent, and the warm bag of being made by this self-generating exothermal agent.
Utilize the exothermic characteristic of metal-powder and oxygen reaction to make the existing more research of heat-generating agent, select metal-powder (Al, Mg and Fe powder) for use as Japanese Patent J56014575, J56001148, these heat-generating agents of J57170252., some acid solution (monovalence, divalence or trivalent chloric acid) or salt (NaCl or potassium permanganate) and gac be as catalyzer, remix silica gel, vermiculite or ash etc.But its cost height, corrodibility is big.In addition, short with the warm bag product soaking time that self-generating exothermal agent is made, the temperature instability, the cost height, thus be not used widely.
An object of the present invention is to provide a kind of self-generating exothermal agent, its cost is low, and corrodibility is little.
Another object of the present invention provides a kind of warm bag, and its soaking time is long, and temperature-stable is with low cost.
Heat-generating agent of the present invention has following composition:
Weight percentages of components (%)
Iron powder 30-85
Perlite is below 15
Float pearl below 15
Gac 1-15
Sodium-chlor 1-15
Water 5-30
Wherein, perlite is not less than 1% with the add-on summation of floating pearl.
Warm bag of the present invention comprises overcoat and is loaded on the interior heat-generating agent of overcoat, it is characterized in that this heat-generating agent has following composition:
Weight percentages of components (%)
Iron powder 30-85
Perlite is below 15
Float pearl below 15
Gac 1-15
Sodium-chlor 1-15
Water 5-30
Wherein, perlite is not less than 1% with the add-on summation of floating pearl.
Self-generating exothermal agent cost of the present invention is low, and corrodibility is little, and is long by the warm bag soaking time of its manufacturing, and temperature-stable is with low cost.
By the adjustment to each component ratio of self-generating exothermal agent, the heating temp of heat-generating agent can change between 40-80 ℃, and heating continuing time is decided by the usage quantity of heat-generating agent.
Wherein iron powder can be steel scale of steel rolling or fine iron breeze reductive iron powder.Iron powder under the effect of support of the catalyst gac and catalyzer sodium-chlor, with oxygen and water generates thermopositive reaction, the perlite that heat insulation property is good and float the effect that pearl can play controls reaction speed simultaneously.
Precious ball rock aboundresources.Floating pearl is a kind of thing that utilizes again of heat power plant's coal ash.Both low prices help reducing the heat-generating agent cost.
The used perlite of the present invention and to float pearl proportion little, the microporosity is many, can absorb large quantity of moisture, is 5 grams as the perlitic water regain of 1 gram.Like this when making heat-generating agent, can simplify and add the water conservancy project skill.Change perlite and float the add-on of pearl, can controls reaction speed, reach the purpose that obtains different heat temperature and fever time.
Heat-generating agent of the present invention does not contain corrosives, and is safe in utilization.
Heat-generating agent of the present invention does not need any outside resources.Just can spontaneous generation heat in air, can be used for making various heating products and heating and heat-insulating device, particularly for being used for heating in the environment that does not have electric heating device and other heating equipments, or at the safe thermal source of the environment that can not use naked light or electric heating type of heating as heat tracing, this heat-generating agent has significant advantage.
Heat-generating agent of the present invention is used to make the human body heating bag, and its production method can be to adopt non-woven fabrics lined with polyethylene bag, in adorn heat-generating agent of the present invention.This warm bag has easy to carry, uses characteristics simple to operate.With the warm bag that heat-generating agent 50 of the present invention is restrained, the heating continuing time in 40-65 ℃ of temperature range is 37 hours, and medial temperature is 58 ℃; Wherein the time length more than 55 ℃ is 28 hours.The warm bag of the same weight that Japan is commercially available, heating temp time length between 40-66 ℃ is 20 hours, medial temperature is 52 ℃.
As seen, the warm bag of heat-generating agent making of the present invention has heating continuing time length, temperature-stable, cost is low, easy to use and the characteristics of safety non-pollution.
