Description
Technical field
The invention belongs to construction material technical field, be related to a kind of light energy-saving environmental-protection board capable of releasing negative ion and its
Preparation method.
Background technique
Tourmaline can ionize hydrone and influence the structure of water, have releasing negative oxygen ion, purify the characteristic of air.Air
Pollution is common and urgently to be resolved one of the problem of environmental pollution of facing mankind.It mainly wraps in the source of polluter in air
Dust particles, the exhaust gas of discharge and suspension microorganism etc. are included, most of they have cation, and excessive cation can make one
Body is easy infection respiratory disease or induces various sub-health states.Tourmaline release negative oxygen ion can not only in air
Cation neutralizes, and can also effectively have an effect with the odor source molecule being attached on wall and ceiling, so that foul smell is not
It generates again, and then plays the role of environment purification.Different from the mode for using ionization mode to generate negative oxygen ion, tourmaline is producing
Other substances harmful for human body such as ozone, active oxygen will not be generated during raw negative oxygen ion, so by people's
Favor extensively.It follows that tourmaline can be referred to as qualified environment-friendly function material.
Chinese invention patent CN106894601A discloses a kind of anion plate and the processing method of the plate, passes through
It is provided with soak in reaction kettle, rare-earth mineral powder, tourmaline powder and wood wool or sawdust are added in soak, and is heated anti-
It answers kettle that soak is made to keep boiling certain time, timber is then taken out from reaction kettle and dries, press to be formed by adhesive
Plate.It is simple to operation that this method is prepared plate process, constantly can outwardly discharge anion for a long time, but by
Sheet mechanical property made of wood wool or sawdust and adhesive pressing is poor, there are some potential safety problems, while anion
Burst size is not high, can not meet human body to the health demand of anion.
It is a kind of same the advantages that meeting low cost, heat preservation energy-saving, high-strength anti-shock, fire-proof sound insulation the present invention is directed to invent
When, it can discharge that negative ion amount is larger, and the sustainable development green wall material of sustained release effect can be reached.
Summary of the invention
In order to solve the problems in the existing technology, light energy-saving environmental-protection board capable of releasing negative ion and its system are prepared
Preparation Method, specific invention are described as follows:
Tourmaline is adulterated using rare earth mineral, tourmaline is modified, and the size of tourmaline is effectively reduced, is improved
The Negative ion disengagement of tourmaline.Using planetary type ball-milling instrument, dehydrated alcohol is situated between as ore grinding solvent, agate ball as ball milling
Matter, filling rate 60%-80%, is prepared tourmaline powder after drying and screening；
Using magnetic stirring apparatus by after 10-15 parts of tourmaline powders and suitable quantity of water stirring 1h, 2-5 parts of 0.5mol/L are added
Ce(NO3)3·6H2O solution continues to stir 30min, continuously adds 1-5 parts of urea and 0.1-0.5 parts of polyethylene pyrroles as cerium source
Pyrrolidone stops stirring after stirring 3-5h under 30 °, and after precipitating completely, filtering, cleans, is drying precipitated at centrifugation, after sintering
Obtain CeO2Adulterate tourmaline powder.
Using the small-size effect of tourmaline, cerium source is added in the dispersion liquid of tourmaline, cerium source will be adsorbed on electrically
Cerous nitrate is converted to CeO by calcining by Shi Shang2.In dispersion process, urea and polyvinylpyrrolidone is added, improves and divides
The pH environment of dispersion liquid, and the dispersion stabilization of solution is improved, avoid the reunion and sedimentation of tourmaline.
Wherein tourmaline powder is one or more of dravite, elbaite, chromium tourmaline and iron tourmaline, warp
Tourmaline powder partial size after ball milling is 50~500 μm.
The present invention controls the partial size of tourmaline by ball-milling technology, and passes through the adjusting of surfactant and solvent, improves
The dispersion stabilization of tourmaline avoids it that agglomeration occurs.After rare earth element and tourmaline are compound, tourmaline can be improved
Can, so that the Fe in tourmaline structure cell2+It is oxidized to Fe3+, unit cell volume contraction, Fe3+Ionic radius is less than Fe2+, electric dipole moment change
When greatly, by temperature or pressure disturbance, tourmaline particle both ends can assemble more charges, so that static electricity pressure increases, it is right
H in air2O degree of ionization increases, therefore release negative ion amount can increased.
In order to save board cost, and the utilization rate of waste being improved, the present invention crushes waste and scrap, it is blended,
Substrate as plate.
