Powder material capable of producing anion and preparation method thereof

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....
