Abstract
The invention provides the self heating material composition that a kind of heating temp is stable, it is characterized in that, in compositions described by weight, the proportioning of each composition is: reduced iron powder 1～10 parts, activated carbon 1～4 parts, coke 1～2 parts, sodium chloride 0.5～2 parts, sodium carbonate 0.5～2 parts, kieselguhr 1～3 parts, aluminium powder 1～4 parts, calcium oxide 1～3 parts, aluminium oxide 2～8 parts, water 10～40 parts.The stable self heating material composition heat production persistent period length of the heating temp of the present invention, reacting balance, it is possible to meet the stable solidification temperature of repairing composite material and requirement hardening time.
Description
Technical field
The present invention relates to chemistry exothermic material, particularly relate to smokeless self heating material composition, send out in particular it relates to a kind of
The self heating material composition of hot temperature stabilization.
Background technology
Construction, instant food and health care apparatus field, use some simple exothermic chemical reaction systems the most in a large number in the wild
The spontaneous heating material become.Before very early, people are known that limestone adds water and can produce amount of heat, here it is chemical exothermal is
Basic application, but this reaction is excessively fierce and also the persistent period is short, not only can not effectively utilize, also pollute the environment, therefore should
The widest by scope.Some are also had to find sodium acetate solution crystallization meeting heat release and can be recycled, but this self-heating material group
Compound system quantity of heat production is the highest, complex process, along with the precipitation of acid in reaction, can corrode packaging material.Also someone uses and has
Certain particle size and the calcium oxide of activity degree or metallic aluminium, ferrum, magnesium and water or certain solution react heat production.For magnesium-water type type
, there is reactant forming process formula complicated in hydration heat reaction system, processing technique requires higher, and energy consumption is big, becomes
This height.The most conventional with calcium oxide-water type hydration heat reaction, this reaction has heat production persistent period length, reacting balance.But
It is under conditions of there is no burning things which may cause a fire disaster, power supply, the technical field of composite repair also need to not had preferable self-heating material,
Disclosure satisfy that the stable solidification temperature of repairing composite material and requirement hardening time.
Summary of the invention
The goal of the invention of the present invention is to provide the self heating material composition that a kind of heating temp is stable, heat production persistent period
Long, reacting balance, it is possible to meet the stable solidification temperature of repairing composite material and requirement hardening time.
The concrete technical scheme of the present invention is the self heating material composition that a kind of heating temp is stable, it is characterised in that
In compositions described by weight, the proportioning of each composition is:
Reduced iron powder 1～10 parts, activated carbon 1～4 parts, coke 1～2 parts, sodium chloride 0.5～2 parts, sodium carbonate 0.5～2
Part, kieselguhr 1～3 parts, aluminium powder 1～4 parts, calcium oxide 1～3 parts, aluminium oxide 2～8 parts, water 10～40 parts.
Further, in described by weight compositions, the proportioning of each composition is:
Reduced iron powder 5 parts, activated carbon 2 parts, 1.5 parts of coke, 1 part of sodium chloride, sodium carbonate 1 part, 2 parts of kieselguhr, aluminium powder 2
Part, calcium oxide 1.5 parts, aluminium oxide 4 parts, 20 parts of water.
The self heating material composition reaction principle that the heating temp of the present invention is stable is that reduced iron powder and coke are as electricity
Pole, is main reactant；Sodium chloride provides ion, forms response circuit；Activated carbon does reaction carriers, stores steam；Diatom
Soil plays catalytic action；Calcium carbonate and sodium carbonate play catalysis, auxiliary thermal source effect；Aluminium powder provocative reaction；Aluminium oxide is put down as temperature
Weighing apparatus agent absorbs heat when heat release is too much or temperature is too much higher than desired temperature, reduces maximum temperature with this, in temperature less than pre-
Heat is released when phase temperature is too much.
Compared with prior art, it is an advantage of the current invention that:
The self heating material composition 1 that the heating temp of the present invention is stable) use aluminium oxide as hygral equilibrium agent, add
After hygral equilibrium agent, absorb heat when heat release is too much or temperature is too much higher than desired temperature, reduce maximum temperature with this, in temperature
Release heat when degree is too much less than desired temperature, enable temperature little scope fluctuation about 90 DEG C of whole solidification process, from
And make the Exotherm Time of originally 5～10min be extended for for 30～40min times；2) whole formula constituent and content are through optimizing, and produce
Thermal endurance length, reacting balance, low cost.
Accompanying drawing explanation
When Fig. 1 is the exothermic heat of reaction of the heating temp of the present invention stable self heating material composition preferred embodiment time
Between temperature chart.
Detailed description of the invention
Below with reference to the drawings and specific embodiments, technical scheme is described in further detail.
Embodiment one
The stable self heating material composition proportioning of heating temp is following:
Reduced iron powder 1 part, activated carbon 1 part, 1 part of coke, 0.5 part of sodium chloride, sodium carbonate 0.5 part, 1 part of kieselguhr, aluminium powder 1
Part, calcium oxide 1～3 parts, aluminium oxide 2 parts, 10 parts of water.
The self-heating material being not added with aluminium oxide is mainly iron powder, aluminium powder, coke, activated carbon, salt, kieselguhr, quick lime, carbon
Acid sodium mixing produces substantial amounts of heat the most at short notice.Add aluminium oxide and can reach the effect of equilibrium temperature,
Absorb heat when heat release is too much or temperature is too much higher than desired temperature, reduce temperature with this, when temperature is less than desired temperature
Put vinegar heat, enable whole process in certain temperature upper and lower little scope fluctuation.
Embodiment two
The stable self heating material composition proportioning of heating temp is following:
Reduced iron powder 10 parts, activated carbon 4 parts, 2 parts of coke, 2 parts of sodium chloride, sodium carbonate 2 parts, 3 parts of kieselguhr, aluminium powder 4 parts,
Calcium oxide 3 parts, aluminium oxide 8 parts, 40 parts of water.
Embodiment three
The stable self heating material composition proportioning of heating temp is following:

Part, calcium oxide 1.5 parts, aluminium oxide 4 parts, 20 parts of water.
It it is optimization formula when material mixture ratio is this proportioning.As shown in Figure 1, fully achieve solidification and repair asphalt mixtures modified by epoxy resin
The requirement of resin-based composite, the requirement that is heating and curing of epoxy resin-base composite material is: heat up 3～5min, heating-up temperature
It it it is 85～95 DEG C, it is possible to insulation 30～35min.
Use this self-heating curing that epoxy resin-base composite material can carry out solidification to repair, enter using the method
The epoxy resin-base composite material of row solidification carries out tensile-sbear strength test, and measuring its value is that specialty vulcanizes instrument solidification intensity
80%, illustrate that this formula system can produce a desired effect, this formula can be used to carry out the repairing that is heating and curing of composite.
