Embodiment 1

[0016] The composition and weight percentage of the powder material capable of generating negative ions of the present embodiment are as follows: 30% magnesium tourmaline, 20% lanthanum phosphate, 30% cerium phosphate, 10% titanium dioxide, 5% zinc oxide, and 5% rockite.

[0017] The preparation process of the powder material of the present embodiment is as follows:

[0018] ① Grind the magnesium tourmaline material to 300 mesh with a jet mill, and roast it in a muffle furnace at 500°C for 1 hour;

[0019] ② Add the magnesium tourmaline material roasted in step ① into the grinding equipment for ultra-fine grinding, and control the particle size distribution of the powder at 200-400nm by means of hydraulic classification;

[0020] ③When the grinding is about to end, add stannous chloride and oxalic acid for surface treatment;

[0021] ④ Grinding cerium phosphate, lanthanum phosphate, titanium dioxide, zinc oxide and icicle until the particle size distribution is less than 1 μm...

Embodiment 2 to Embodiment 4

[0025] The rest are the same as in Example 1, except for the composition of the powder material and its weight percentage (see Table 1), preparation process parameters (see Table 2), and test results (see Table 3).

Abstract

The present invention discloses one kind of powder material capable of generating negative ion and its preparation process. The powder material consists of tourmaline material 20-70 wt%, mixed RE material or mixed RE oxide material 20-60 wt%, semiconductor catalyst material 5-20 wt%, and auxiliary exciting material 4-15 wt%. Its preparation process includes the following steps: 1. crushing and roasting tourmaline material; 2. grinding tourmaline material in a grinding set into superfine powder; 3. adding surface treating agent for surface treatment; 4. grinding the other materials to size smaller than 1 micron; and 5. dispersing all the materials inside one high speed dispersing machine, sieving and drying. The powder material has a negative ion releasing rate up to 6000-10000 / cu cm.

Description

technical field [0001] The invention relates to a powder material capable of generating negative ions and a preparation method thereof. Background technique [0002] During a long historical period, positive and negative ions in the earth's atmosphere automatically maintained a balance. In the past hundred years, due to industrial waste discharge, garbage incineration, toxic chemical components, electromagnetic radiation pollution, derivatives of bacteria and viruses, etc., have become the culprits of the sharp increase of positive ions and the sharp decrease of negative ions, and appropriate artificial methods should be adopted to increase the concentration of negative ions in the air , is an effective remedy for improving the earth's environment and protecting human health. [0003] Man-made negative ions mainly use high-voltage electrostatic fields, high-frequency electric fields, ultraviolet rays, radiation and water impacts to ionize the air and generate negative ions....
