Abstract
This invention discloses a method for preparing a kind of negative-ion material. When the particle diameter of tourmaline is disintegrated below 1 micrometr, its one end is electrically positive and the other end is electrically negative, and this will formide its further disintegrating. This invention solves this special electrical characteristic of tourmaline primarily. According to this method, we can get dimensional stable ultra-fine microcrystal tourmaline, advance its function of releasing negatron by times. This method uses wet agitation to mill super fine powder. The super fine ourmaline powder, whose particle size is fine, distribution is thin, particle shape is regular, is prepared through using disperser reasonably, milling medium, optimizing technological condition, and so on.
Description
Technical field
The present invention relates to a kind of preparation method of coating raw material, especially a kind of preparation method with coating raw material of negative ion-releasing function.

2Deng.The characteristics of tourmalinite mineral are to have piezoelectricity and pyroelectricity, under the situation of temperature, pressure change, can cause tourmalinite crystalline potential difference, make ambient air generation ionization, on contiguous water molecules and oxygen molecule, and made it be converted into negative aeroion by the electron attachment hit.The negative ion of Fa Shenging moves in air thus, gives bacterium, dust, smoke particles and water droplet etc. with negative charge transport, and electric charge combines with these particulates, can reach the purpose that purifies air.
Therefore, tourmalinite is a kind of good environment functional material, is used for the coated material of indoor paint and furniture, electrical equipment etc., it is advantageous that to produce negative ion, purifies the air of a room.In addition, because of its pyroelectricity, along with variation of temperature, crystallizable mineral body two ends can produce voltage, its polarity ion causes that in the equilibrium theory of tide vibration dipole moment changes, produce the electromagnetic radiation of far infrared band, ir radiation can make human body produce heat effect and resonant absorption effects, and human body is had health-care effect.But when the tourmalinite particle diameter is big, this effect is not obvious, and people are broken into small-crystalline according to the understanding to crystal property with macrocrystal, find that its emitting electrons has improved the ability of ambient air negative ionization, that is to say with negative ion concentration in apparatus measures unit's air has increased.Therefore people manage to utilize the modern age superfine technique that tourmalinite is carried out superfine grinding very naturally, but when tourmalinite is crushed to particle diameter less than 1 micron, tourmalinite shows peculiar charged characteristic, the tourmalinite crystal is an a kind of end positively charged, the electronegative polar molecule of the other end, just limited it and further pulverized, obviously, it has brought a new difficult problem to comminution engineering.But the superfine grinding of tourmalinite is imperative again, this is not only in order to give full play to the function (bringing into play the function of its natural anion generator in other words) that it discharges negatron, but also be needs for following process, Here it is the technical barrier that will solve required for the present invention.
Summary of the invention
