Description
Technical Field
The invention relates to a filling material and application thereof, in particular to a filling material with good phase change energy storage.
Background
In summer, the physiological needs of each person are sunstroke prevention and cooling. The existing cooling modes such as an electric fan, an air conditioner and the like can play a good integral cooling effect. However, the above-mentioned methods need to be driven by electricity, and the cooling effect for many contact surfaces (such as sofas, chairs, beds, etc.) is not obvious. Aiming at the problems, summer sleeping mats, summer sleeping cushions and summer sleeping pillows are applied.

Detailed Description
The present invention will be further described with reference to the following examples.
A filling material comprises Natrii sulfas, Cork wood granule, glycerol and solid sulphuric acid powder. Mirabilite, namely sodium sulfate decahydrate is a typical phase-change energy storage material without accumulated water and salt, but has the phenomena of supercooling and phase separation, namely, sodium sulfate decahydrate is inconsistently melted at the temperature of 32.4 ℃, and the solid-liquid layering phenomenon can occur under the action of gravity. The phenomenon is not only very unfavorable for phase change heat storage, but also over-soft phenomenon can occur due to the appearance of liquid in the cooling object filled with the filling material. The cork particles as the suspending agent have the advantages of good elasticity, sealing property, heat insulation property, wear resistance, no toxicity, no odor, small specific gravity, softness, volume increase after water absorption, chemical erosion resistance and no precipitation of the suspending agent all the time.
For example, the material is filled into a cushion, the cushion can become a 'water cushion' in summer due to the fact that the temperature of a human body exceeds 32.4 ℃, a person sits on the cushion, the cushion can shake left and right to bring abnormal sound, and experience feeling is poor. The cork granule has extremely strong hydroscopicity, and more importantly, after the cork granule absorbs the water containing salt, the volume increase trend is obvious, so that the cork granule and the anhydrous sodium sulfate can be similar in volume, the whole water cushion can keep particulate matter, and the experience comfort level is effectively improved. After the cork particles absorb the water containing salt, the cork particles are often bonded with anhydrous sodium sulfate due to intermolecular attraction, and the occurrence of the phenomenon can cause the cushion to be caked and bring discomfort. Meanwhile, the cork particles and the sodium sulfate decahydrate are often adhered together, and discomfort is also brought. The problem can be well solved by adding the glycerol, the glycerol can ensure that sodium sulfate decahydrate particles, anhydrous sodium sulfate and cork particles are not adhered together, the self-leveling effect is achieved, and the comfort level is effectively improved.
Meanwhile, in order to better solve the solid-liquid separation problem of the sodium sulfate decahydrate, solid sulfuric acid powder is added. Firstly, after solid sulfuric acid powder is melted into water, the water becomes acidic, and the suspension of sodium sulfate decahydrate crystals can be promoted; secondly, the solid sulfuric acid powder is durable and can effectively ensure long-term use.
Furthermore, in order to solve the problem of supercooling of mirabilite, a nucleating agent is added and serves as particles of a crystallization generation center, so that crystallization can be smoothly performed at a freezing point, and supercooling is reduced or avoided. And also, since the difference in the density of the nucleating agent results in a portion not being effective in its nucleating action, a thickening agent is added in an amount so as to increase the concentration of the solution to prevent the hydrated salt from aggregating, but not to hinder the phase transition process.
Furthermore, as borax decahydrate and mirabilite have the same crystal form and similar atomic arrangement, and the difference of the lattice parameters of the borax decahydrate and the mirabilite is lower, the nucleating effect is better when the borax decahydrate is used as a nucleating agent.
Furthermore, the closed cavity is made of hard materials, and the filling material is filled into an iron door, a stainless steel door and a wooden door, so that the sealed cavity can be used as a fireproof door. The fire door is manufactured by utilizing the principle that the filling material absorbs a large amount of heat, and is particularly suitable for refuge rooms for underground mining. Compared with the traditional materials such as asbestos tiles and the like, the heat absorption device has the advantages of small volume and large heat absorption capacity, and is convenient to install and use.
Example 1. Cool pillow, the inner filler of which contains 300g of mirabilite, 600g of cork granules, 1.8g of glycerin, 0.26g of powdered sulfuric acid.
Example 2, a cooling mat, the inner filler of which is 330g of mirabilite, 670g of cork particles, 1.7g of glycerin, 0.26g of powdered sulfuric acid.
Example 3, compared with example 1, the filling material is filled into a bedding cushion, belongs to bedding articles, and is also added with carboxymethyl cellulose and borax decahydrate.
Example 4, compared with example 3, the hexagonal sodium metaphosphate is further added, and the hexagonal sodium metaphosphate is used as a crystal structure changing agent, so that the crystal particle sizes of the anhydrous sodium sulfate and the sodium sulfate decahydrate can be effectively controlled, and the crystals are fine and uniform.
After the materials are filled, when the temperature exceeds 32.5 ℃, mirabilite begins to change from a crystalline state to a liquid state, and at the moment, the cork particles begin to fully absorb moisture, and meanwhile, the glycerin and the sulfuric acid powder still play roles. Finally, the filler in the cushion is ensured to be granular, and the cushion has excellent experience and comfort. When the temperature is reduced, the anhydrous sodium sulfate absorbs the water in the cork grains and turns into a crystalline state, the filler in the cushion is still granular, the consistency before and after use is kept, and excellent experience is brought. In order to solve the problem that supercooling causes adverse effect on phase change heat storage, a nucleating agent, a thickening agent and a crystal structure changing agent are added, so that the cushion filled with the filler disclosed by the invention is good in front-back shape consistency, good in cooling effect and excellent in use experience.
The filling material stores energy by utilizing the phase change latent heat of the phase change material. Through the addition of the cork particles, the glycerol and the sulfuric acid powder, the whole filling material is ensured to be kept in a granular state to the maximum extent when the mirabilite is supercooled and separated, and the problem of poor comfort caused by excessive traditional liquid and solid-liquid separation is solved.
Example 5, a stainless steel door with a closed cavity filled with mirabilite, cork granules, glycerin and solid sulfuric acid powder. Compared with the traditional fireproof door, the stainless steel door has the advantages that the volume is easier to move, the installation is convenient, the flame-retardant and heat-insulation effect is better, open fire is automatically extinguished, and the like.
It should be understood by those skilled in the art that the protection scheme of the present invention is not limited to the above-mentioned embodiments, and various permutations, combinations and modifications can be made on the above-mentioned embodiments without departing from the spirit of the present invention, and the modifications are within the scope of the present invention.
