The invention also relates to a pad body, in particular relating to a pad body containing the phase-change constant-temperature material. The phase-change material can ensure constant temperature within a certain period of time, is large in latent heat and stable in property, and can be repeatedly used. The phase-change material is fine and smooth like sand as compared with the original phase-change material. The phase-change material is prepared through the following steps: evenly mixing 16wt%-20wt% of water, 1wt% of thickener, 3wt%-4wt% of nucleating agent and 1wt% of dispersing agent, so that the mixture is of a uniform thickness shape; adding 75wt%-78wt% of mirabilite; and evenly mixing so that the components are evenly dispersed. The phase-change material can be added in the pad body to serve as a cold-hot bag, and insulation is durable. The pad body containing the phase-change material consists of small grids which are of strip shapes, the grids are tightly distributed, and a pouring material port is reserved on each grid and used for pouring the phase-change material.
Description
Technical field
The present invention relates to a kind of phase change material, be particularly related to a kind of phase-change constant-temperature material.
The invention still further relates to a kind of pad, particularly comprise the pad of phase-change constant-temperature material.
Background technology
Phase change material (PCM-Phase Change Material) is meant and varies with temperature and change form and the material of latent heat can be provided.Phase change material by solid-state become liquid state or become solid-state process by liquid state be called phase transition process, at this moment phase change material will absorb or discharge a large amount of latent heat.In fact phase change material can be used as energy accumulator.This specific character is energy-conservation, and there is great meaning in fields such as temperature control.
Existing phase transformation low temperature energy storage material is mainly with Na
2SO
410H
2O is a main raw material, and its unit mass energy storage calorific value is very big, is about 241 Jiao/grams; But, Na
2SO
410H
2The dissolution process of O belongs to non-homogeneous dissolving, and there is the cold and phenomenon of phase separation of serious mistake in it, and pure Na
2SO
410H
2O tangible layering just occurs after through 3 to 4 thermal cyclings in the system, its enthalpy of phase change also will decay to 20 to 30 Jiao/grams.Just inorganic hydrated salt has advantages such as energy storage is big, cost is low, safety non-toxic, has great use value.Simultaneously inorganic hydrated salt have again condensate depression big, be easy to generate shortcoming such as be separated, limited its use.
Based on the problems referred to above, the present invention wants by adding nucleator, dispersion agent, thickening material, eliminates or has reduced its restriction significantly.
Summary of the invention
Problem to be solved by this invention is: a kind of phase change material is provided, makes it can accomplish constant temperature in the regular hour, and latent heat is big, stable performance, and can use repeatedly.This phase change material can be accomplished fine and smooth as sand than original.
For addressing the above problem, the present invention is achieved in that a kind of phase-change constant-temperature material, press mass ratio by the water of 16%-20%, 1% thickening material, the nucleator of 3%-4%, 1% dispersion agent, stir, make mixture be the thick of homogeneous, add the saltcake of 75%-78% then, restir is even, and each component is uniformly dispersed.
Dispersion agent is a kind of interfacial agent that has lipophilicity and two kinds of opposite nature of wetting ability at intramolecularly simultaneously.But homogeneous disperses those to be difficult to be dissolved in the inorganic of liquid, and the solid particulate of pigment dyestuff also can prevent the sedimentation and the cohesion of solid particulate simultaneously, forms the stable required medicament of suspension.
Nucleator can see through the crystallization behavior that changes resin, accelerate crystallization rate, increase crystal density and impel fine grain sizeization, reach the new functional agent that shortens shaping cycle, improves physical and mechanical propertiess such as the goods transparency, surface luster, tensile strength, rigidity, heat-drawn wire, shock resistance, creep resistance.
Thickening material is a kind of high-content, low viscosity polyacrylic acid emulsion, so shear viscosity has good flowability, levelling property and anti-gradually property in main the increasing, high thickening is renderd a service, and consumption is little, and anti-dilution property good (dilution back viscosity changes little), stable storing, anti-mildew become and good prescription suitability.Disperse because low-shear viscosity hangs down in emulsion paint very easily, do not have the phenomenon of luming because of the local overrich of thickening material, thickening phenomenon without male offspring, generally stir reached in 5-10 minute MV minium viscosity 90% on.
The phase change material of making according to the method described above can keep homo(io)thermism in the regular hour, and latent heat is big, stable performance, can use repeatedly, no side effects, and cheap, this phase change material also safety is easily produced.And because added dispersion agent therein, thus than before material can be fine and smooth more.
Another problem to be solved by this invention is: use can be used as cold and hot bag in the above-mentioned phase change material adding pad, insulation is lasting.
For solving technique scheme, the present invention is achieved in that a kind of pad that contains phase-change constant-temperature material, and pad is made up of little grid, and grid is strip, closely arranges between the grid, and each grid all leaves irritates charging bole perfusion phase change material.
Described all grid are tiled in the horizontal plane.Grid can also be to be tiled in the perpendicular.
A kind of pad making method that includes phase change material may further comprise the steps:
(1) gets the raw materials ready:, select for use and cutting pad material according to the physical dimension and the material requirements of mat;
(2) bag: form sack by two matrix material compactings;
(3) can of phase-change constant-temperature material;
(4) limit, bound edge are sealed, cut in can well;
(5) check and packing: inspection pad physique amount, to the packing of product warehouse-in that is up to the standards.
Pad is that the two sides with compound plastic layer in the matrix material stacks, and heating makes the plastic layer surface melting, makes the sack of bar shaped grid.
Described pad matrix material is dry goods, silk fabric class composite PVC.
The beneficial effect that the present invention brought is: no matter pour into above-mentioned phase change material in pad, can be incubated in long-time, be to continue Bao Rewen or cold insulation temperature, can both remain unchanged in long-time.
