preparation example Construction

[0036] The present invention also provides a preparation method of lightweight magnetic balls, comprising:

[0037] S10, preparing ceramic hollow spheres.

[0038] Firstly, ceramic slurry is prepared, and then the ceramic slurry is evenly coated on the surface of polystyrene spheres layer by layer, and then sintered and cooled to obtain the ceramic hollow spheres.

[0039] The preparation method for preparing the ceramic slurry is as follows: first, fully mix 65-85 parts of zircon, 40-60 parts of calcined kaolin, and 10-15 parts of attapulgite to make ceramic powder; then press 50-60 parts of ceramic powder % (mass ratio, unless otherwise specified, the following percentages are all mass ratios), the ratio of 40% to 50% of the powder solvent is mixed, ground for a certain period of time, and the ceramic slurry is obtained. The powder solvent includes a first dispersant, a thickener, a binder and water, and the mass proportions of each component are: 0.1-0.3% of the first disp...

Embodiment 1

[0057] The preparation method of the present embodiment ceramic hollow sphere comprises:

[0058] Fully mix 65 parts of zircon, 40 parts of calcined kaolin and 10 parts of attapulgite to prepare ceramic powder.

[0059] The powder solvent is configured according to the following component ratios: 0.1% sodium polyacrylate, 0.05% sodium carboxymethylcellulose, 1.0% dextrin, and 98.85% water.

[0060] Mix according to the ratio of 50% of ceramic powder and 50% of powder solvent, put into planetary ball mill and grind for 6 hours to prepare ceramic slurry.

[0061] Put the steam-expanded polystyrene sphere into the drum, set the rotating speed at 8 rpm, raise the temperature inside the drum to 35° C., and then add the ceramic slurry. During the rotation of the drum, the ceramic slurry is uniformly coated on the surface of the polystyrene sphere, and when the polystyrene sphere coated with the ceramic slurry reaches a specified size, the polystyrene sphere is dried.

Embodiment 2

[0065] The preparation method of the present embodiment ceramic hollow sphere comprises:

[0066] Fully mix 75 parts of zircon, 55 parts of calcined kaolin and 12 parts of attapulgite to prepare ceramic powder.

[0067] The powder solvent is configured according to the following component proportions: 0.3% of methacrylic acid amine, 0.15% of hydroxypropyl cellulose sodium, 1.0% of polyvinyl alcohol, and 98.55% of water.

[0068] Mix according to the ratio of 60% of ceramic powder and 40% of powder solvent, put into a planetary ball mill and grind for 6 hours to prepare ceramic slurry.

[0069] Stir and mix the steam-expanded polystyrene spheres and the ceramic slurry with a high-speed mixer, and filter out the polystyrene spheres whose surfaces are covered with the ceramic slurry for every 1 hour of stirring, and dry them. Repeat this 3 times.

[0070] Send the dried spheres to a high-temperature sintering furnace for sintering, raise the temperature to 700-800°C at a rate o...

Abstract

The invention relates to the technical field of magnet therapy, in particular to a light magnetic ball and a preparation method thereof. The light magnetic ball comprises a ceramic hollow ball and a magnetic resin material layer attached to the outer surface of the ceramic hollow ball. The internal ceramic hollow ball is small in density and firm in structure, and can provide stable support for the magnetic resin material layer on the outer layer. The magnetic resin material layer is formed by mixing magnetic powder and resin, wherein the magnetic powder can generate a stable magnetic field toachieve magnetic therapy effect, and the resin can reduce foreign body sensation generated in the using process of the light magnetic ball, thereby effectively improving comfort degree in use. The light magnetic ball provided by the invention has the advantages of small density, firm structure, wear resistance, corrosion resistance and the like, can meet the demand for magnetic therapy when arranged on products such as quilts, greatly reduces the weight of the products, and is more comfortable to use.

Description

technical field [0001] The invention relates to the technical field of magnetic therapy, in particular to a lightweight magnetic ball and a preparation method thereof. Background technique [0002] With the popularization of the theory of magnetic therapy health care, consumers also increasingly recognize the efficacy of magnetic therapy, and a wide variety of magnetic therapy health care products have appeared on the market. Among them, more and more bedding products also have the effect of magnetic therapy, and consumers can get magnetic therapy health care during sleep to eliminate daytime fatigue. [0003] CN209661125U discloses a kind of magnetic health-care duvet, is provided with a large amount of magnetic particles in its quilt cover, makes this duvet have the magnetic therapy health care function. In addition, most of the magnetic therapy quilts currently on the market also adopt the above-mentioned structure, and realize the function of magnetic therapy by attachi...
