Description
Technical field
This utility model relates to a kind of disposable spontaneous hot paste of controlled heating speed, relates in particular to a kind of disposable spontaneous heat posted for outdoor activities.
Background technology
In low temperature sleety weather or cold winter, when people carry out the outdoor activities such as daily outdoor study, outdoor maintenance, field exploration, outdoor military affairs, rescue and relief work, take certain warming, heating measure to be very important.
Existing heating mode, as space heater, warm hand bag, hot water bag, portable hand warmer (charge type, cell type), hot-water heating, fire coal, combustion gas, firebrand etc., all take electric energy, water energy, chemical energy etc. preheats accumulation of heat heating as the energy carries out direct heating or indirect type, during heating, need the inconvenience near the heating energy to leave, also or the freely movable activity that is but not easy to both hands of bosom heating object short distance, the feature limits of these heating modes its application in activity out of doors.
During outdoor activities due to without available power supply or traditional heat source, simultaneously can not bound activity characteristic based on both hands, the spontaneous heat posted of portable disposable just seems particularly applicable.The most representative being applied as of spontaneous heating technology " warmer treasured ", also claims warming subsides, heating paste, warming sheet, a subsides heat, warms up foot subsides, carry-on warm subsides etc., and its raw material is generally the synthetic mixture such as iron powder, water, active carbon, salt and Vermiculitum.During " warmer is precious " heat production, its vacuum packaging is opened along entry, throw off lining paper below, make airborne oxygen can enter smoothly its inside and contact heatable with raw material.By controlling oxygen, see through the oxidation reaction process that ability can be controlled iron powder, thereby control the time of maximum temperature, heating speed and the persistent fever of product.And this process is mainly to be realized by the cloth bag of coated raw material, the core of cloth bag is air-permeable layer.
Report about plain edition warmer is existing many.It is precious by bamboo charcoal warmer that patent CN 202647967 U have announced a kind of foot, comprises outer bag, inner bag and exothermic material.Wherein, inner bag comprises non-weaving cloth and applies the breathable film (punching PE film) on non-weaving cloth.CN 201220445438.7 discloses a kind of novel heating paste, comprises back bakelized paper, gum layer, heating layer, ventilated membrane, non-weaving cloth.Wherein, ventilated membrane and non-weaving cloth are successively in a side of heating layer.CN 201220458295.3 discloses a kind of heating paste, comprises non-woven cloth bag.Wherein, non-woven cloth bag is provided with some air-vents, and in non-woven cloth bag, top and bottom are equipped with ventilative rete.
In above several method, user cannot be controlled Oxygen Flow flux according to the actual needs of oneself, regulates the heat release time of warmer.Meanwhile, ventilated membrane mostly is thermoplastic resin and makes, and in order to reach certain air permeability, itself is very thin and mechanical strength is less.And the mixture that the content of spontaneous heating material is dusty raw materials, wherein the raw material such as iron powder, Vermiculitum, active carbon is all tiny graininess (minimum about 200-300 order), once having, the packaging bag of content breaks, even very little hole, as long as air can enter in a large number, all may introduce a large amount of oxygen and heat production aggravation, user bears the risk being burned, and has certain potential safety hazard.
CN 102774102 A have announced micro-ventilated membrane and the application in Self-heating warming pastes thereof that a kind of air penetrability changes with temperature.Micro-ventilated membrane comprises base cloth (non-weaving cloth or woven fabric) and is coated in the key-course of base cloth one side that (fusing point is 40-80
othe paraffin of C, Cera Flava or ethylene waxes).In this patent, air penetrability is very big at low temperatures for the prepared warming subsides of micro-ventilated membrane, but is greater than specific temperature (68
oc), after, air penetrability declines rapidly.From the product feature of this patent, we can find out, its key-course principle of control temperature rub and make key-course produce slight crack after oxygen enter the oxidation reaction heat production that participates in iron powder; The wax melting that thermal accumlation reaches key-course after uniform temperature is infiltrated air-vent and is produced and stop up, and cuts off extraneous oxygen and makes reaction terminating, thereby stop warming subsides to continue to heat up.Although this kind of method reaches the object of anti-scald, be easy to cause raw material unreacted to produce waste completely, meanwhile, after air-vent stops up, because raw material has oxygen around, temporary can the delay stops the effect heating up, and has and causes the danger of scalding.
Utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of disposable spontaneous heat posted of controlled heating speed, is provided with the sticker paper that multi-disc can independently be peeled off, and can tear according to user's body situation the sticker paper of different sheet numbers, regulate the various flows flux of oxygen, and then control the heat release time.
This utility model is the object that reaches above-mentioned, adopts following technical scheme:
A kind of disposable spontaneous heat posted of controlled heating speed, for Bag structure, described bag comprises sticker paper, glue-line, non-woven cloth bag and exothermic material, wherein, described sticker paper relies on glue-line to stick on the outer surface of non-woven cloth bag, described non-woven cloth bag is to be composited by inside and outside two-layer non-weaving cloth and middle microporous breathable film, and non-woven cloth bag is in-built exothermic material; Described bag has the positive back side, and positive back to human body use, the back side is used towards human body, and the positive back side is equipped with sticker paper, wherein, the sticker scraps of paper that front is provided with multi-disc and can independently peels off, the back side is provided with the 1 sticker scraps of paper that can independently peel off.
The PE ventilated membrane that the microporous breathable film of described non-woven cloth bag adopts filler-pulling method to prepare, its grammes per square metre is (40-60) ± 1g/m
2, air permeability is 2700-3500s; It is Exxonmobil that the PE of described PE ventilated membrane adopts linear low density polyethylene LLDPE(production firm) and low density polyethylene (production firm is Hanwha).
Described exothermic material is the exothermic material that iron powder, activated carbon, Vermiculitum, water, salt mix.
The beneficial effects of the utility model are:
1, the sticker paper in described bag front is designed to multi-disc and can independently peels off, and tears the sticker paper of different sheet numbers according to user's body situation, and then controls the various flows flux of oxygen, the heat release time of the spontaneous heat posted of scalable;
2, the microporous breathable film in described non-woven cloth bag adopts polyethylene (PE) ventilated membrane prepared by filler-pulling method, can design the heating speed that different air permeabilities is controlled disposable spontaneous heat posted;
3, in addition, described disposable spontaneous heat posted has Self-adhesive, easy to carry and without the feature of the external energy, especially non-woven cloth bag of the present utility model is made sandwich type structural by two-layer non-weaving cloth and microporous breathable film, can increase temperature retention time, increase the mechanical strength of bag simultaneously, be applicable to very much the Emergency use in various outdoor activities processes.
