Problems solved by technology

Another method is to excite tourmaline by adding a large amount of rare earth element compounds or rare earth compound salts, but its radioactivity exceeds the standard, and at the same time, the far-line emission rate is low
The prior art has the following defects: 1. The powder negative ion release rate is low; 2. The energy consumption in the production process is high, which wastes resources; 3. The powder particle size is large and the application range is narrow; 4. It is easy to cause pollution during production, which is not conducive to Environment; 5. Powder far-infrared emission rate is low

Embodiment 1

[0026]Weighing 80% of columnar tourmaline ore, 10% of rare earth concentrate and 10% of anatase titanium dioxide, preliminarily mechanically pulverizing the natural tourmaline ore and rare earth ore, and passing the natural tourmaline ore, rare earth ore and anatase titanium dioxide through a ball mill Grind and mix for 4 to 6 hours, pass through a 325-mesh sieve, mix the sieved powder with corundum balls and water into a 1:1:4 slurry, and add 0.5% to 5% of chelated titanium lactate or Monoalkoxy titanate, grind for 6 to 12 hours in a rolling ball mill, put the ground slurry into a rotary ball mill, replace the abrasive with zirconium balls, rotate and grind for 12 to 56 hours, and dry at 110°C to 200°C. After removing the moisture from the slurry, the dried powder is dispersed, pulverized and ground in a jet mill, and the final particle size is D 50 ≤0.5 microns.

Abstract

The invention relates to an ultrafine high-effect negative ion powder material, which comprises: 60~95% natural negative ion releasing material, 2~30% activated material, and 3~25% energy transfer material. Wherein, using dry way and wet way to ultrafine break the material and obtain the product. This material increases the ion releasing ability more than twenty times to pure natural tourmalin and three times to the material theoretic value, and has high far-infrared radiation function without toxin.

Description

technical field [0001] The invention relates to an ultrafine and efficient negative ion powder material and a preparation method thereof. In particular, it relates to a negative ion powder material obtained by using natural negative ion releasing materials, excitation materials and energy transfer materials through ultrafine pulverization technology. Background technique [0002] At present, the production of negative ion release materials mainly uses calcination to excite the piezoelectricity and electric self-polarity of the negative ion materials and increase the negative ion release rate. The particle size of the negative ion powder is D 50 ≥5 microns. Another method is to excite tourmaline by adding a large amount of rare earth element compounds or rare earth complex salts, but its radioactivity exceeds the standard and the emissivity of far-line and external lines is low. The prior art has the following defects: 1. The powder negative ion release rate is low; 2. The ...
