Description
Technical field
The present invention relates to solid heat storage field of material technology, more particularly to a kind of solid heat storage applied to pouring molding
Material.
Background technique
Heat-storing material is a kind of new chemical material that can store thermal energy.It is under specific temperature (such as phase transition temperature)
Object phase change occurs, and along with absorbing or releasing heat, can be used to the temperature for controlling ambient enviroment, or to store thermal energy.
It stores heat or cooling capacity, it is released again when needed, to improve the utilization rate of the energy.But at present
The common heat-storing material that market uses has the following disadvantages and problem.
1. heat-storing material specific heat capacity is low
(once required or release heat is often raised and lowered in material to common heat-storing material specific heat capacity, is characterization accumulation of heat
The parameter of material heat storage capacity) it is small, it is substantially all in 1 (J/g.k) hereinafter, influence the realization and promotion of amount of stored heat and accumulation of heat rate,
Cause heating scarce capacity；
2. the heat transfer crisis of hot dynamic process
Common heat-storing material thermal coefficient is small, and it is unfavorable to conduct heat, these heat-storing materials are typically all the shaped brick of compression moulding,
Constitute thermal storage equipment when brick and brick between gap and with insulating layer contact surface generate thermal contact resistance, thermally conductive deficiency and thermal contact resistance
Superposition, make heat storage heat transfer deterioration, heat cannot export in time, cause electric heater self heating and burn；
3. use process and the manufacturing process feature of environmental protection are poor
Using the prefabricated profiled shaped brick of common heat-storing material, in component devices be not it is closed, together with thermal insulation material one
It rises, is communicated with atmosphere, slag that shaped brick and thermal insulation material are split away off, bits, dirt, taste enter room, ruin the air quality in room.
4. complicated component is out of control, performance is uncontrollable, unstable
The iron powder that heat-storing material in the market uses has drawn from tailing, and complicated component, impurity is more, especially contains some eutectics
Point, volatile substances increase material reheating linear shrinkage (%), refractoriness variation, shock resistance variation, volume change
Greatly, cracking, specific heat capacity lower, and are used for a long time and generate decaying, and heat-storing material loses function too early, and equipment cannot work.
5. high production cost
Common heat-storing material is needed during the manufacturing using a large amount of mold and large tonnage pressing machine, and is needed
High-temperature sintering apparatus, so that the technical process of preparation is relative complex and difficulty is big, high temperature sintering is harsher to environmental requirement, also
It needs to carry out subsequent processing.
Summary of the invention
The object of the present invention is to provide a kind of solid heat storage materials applied to pouring molding.
It is a further object of the present invention to provide the preparation methods of the solid heat storage material.

Preferably, iron powder partial size is 100-200 mesh.
Preferably, the water-reducing agent is polycarboxylate water-reducer.
The preparation method of solid heat storage material material applied to pouring molding of the invention, weighs the Black Warrior in proportion first
Rock, water-reducing agent, sodium metasilicate are thoroughly mixed, and are then proportionally added into water and are sufficiently stirred again, i.e. acquisition solid heat storage material.
The present invention is the specific heat capacity by improving heat-storing material using basalt, and adding the iron powder of ratio, to improve its thermally conductive
Coefficient and density of material, in pouring molding, since the addition of sodium metasilicate can generate gelling and sinter effect by it,
In conjunction with a small amount of polycarboxylate water-reducer and water, mixing can be made to have preferable mobility, and made through high temperature pouring molding
Solid heat storage material have the good property built.
Compared with prior art, the invention has the following advantages:
1, the solid heat storage material composition of the application is simply controllable, easy, low cost of drawing materials；
2, function admirable, stability are good.The heat-storing material specific heat capacity of the application is big, and has good temperature to stablize
Property, i.e. temperature change causes specific heat capacity variation small, is shown in Table and shows, and be used for a long time unattenuated；There is good linear shrinkage stability,
I.e. reheating linear shrinkage very little, volume change are small；There is good thermal shock resistance, rapid cooling is not split under high temperature；Have chemical steady well
The micro- molten, evaporation of local part, peculiar smell, embrittlement, dusting, scaling-off, floating is not generated under qualitative and physical stability, high temperature or reheating
Dirt, it is rotten phenomena such as, long-time service do not crack, not scaling-off, not dusting, and refractoriness is high and does not change；It is the five poisonous creatures: scorpion, viper, centipede, house lizard, toad, tasteless；
3, safety and environmental protection, solid heat storage material of the invention can be such that heat storage, electric heater and thermal insulation material is completely formed
Enclosed construction, zero-emission do not influence environment, and water, vapor and particulate matter can not immerse, and class of safety protection is higher than country
Standard；
4, good mouldability and conductivity of heat.
