Description
Technical field
The present invention relates to paint field, especially, be related to a kind of radiation shielding coating with formaldehyde reduced for a long time effect and its
Preparation method.
Background technology
Early in the 70's of 20th century, European Section scholar refers to after having carried out comprehensive system research to room air impact
Go out：From 500 gas chromatographies of room air detection, there is more than 20 kind of carcinogenic substance.The World Health Organization《The world defends
Raw report》In statistics, the nearly half people in the whole world suffers from breathing problem in indoor pollution because of indoor environmental pollution
Patient accounts for the 36% of world population, and chronic accounts for 23%, and tracheitis, bronchitis and patients with lung cancer account for 17/1000ths.
Chinese interior decoration association indoor pollution detection observation center understands, and in numerous ornament materials, toxic material accounts for 68%, meeting
Produce more than 300 kind of VOC（VOC）, and causing more than 30 kind of disease, induction property cancer is projected the most.Market
On interior/exterior decoration material great majority be organic material or organic/inorganic composite material, they contain a large amount of VOC, such as first
The noxious materials such as aldehyde, benzene, after making moist easily colour fading, yellowing, mouldy, come off, and there is easily aging and inflammable safety
Hidden danger.Therefore research safety, the building and ornament materials of nontoxic, good weatherability become study hotspot, greatly develop such building dress
Exterior material is the needs of the demand in epoch and reality.To being capable of the grinding of inorganic coating of anion releasing in prior art
Study carefully, but the anion composition that can be discharged added in most of inorganic coatings, the limited amount of anion releasing, and cost
Higher, the cooperation between the selection of inorganic coating raw material and raw material does not reach optimum efficiency, so as to affect the releasing effect of anion,
And the performance of coating.
Produced during the household electric appliance operation such as business automation equipment and micro-wave oven, radio, television set, computer and mobile phone
The electromagnetic wave of raw various different wave length frequencies.These electromagnetic waves are full of space, can penetrate including many things including human body
Matter, by exceeded dose of radiation.
For deficiency of the prior art, it is badly in need of a kind of radiation shielding coating of research, for the principal item of high-performance coating,
Can be cooperated by organic matter and inorganic matter, play good and lasting radiation proof, degradation of formaldehyde effect.
Content of the invention
The invention provides a kind of have the good environmental protection coating material for removing effect to indoor VOC, particularly
PARA FORMALDEHYDE PRILLS(91,95) has the good environmental protection coating material for removing effect.
A kind of radiation shielding coating with formaldehyde reduced for a long time effect, including following main component：
Nanometer grade silica 0.5-2%
Conductive fine powder 1-3%

Quartz sand 2-5%
Powdered whiting 15-25%
Oyster shell whiting 45-60%
2,4 dinitrophenyl hydrazine 0.02-0.05%
Iron, molybdenum houghite 0.5-0.8%
Nano titanium dioxide 1-3%
Plant cellulose 3-6%
Diatomite surplus.
A kind of preparation method of the radiation shielding coating with formaldehyde reduced for a long time effect, comprises the following steps：
Step one：Sodium metaaluminate and NaOH are dissolved in deionized water and are configured to solution A；Iron chloride is dissolved in deionized water join
Make solution B；Solution C is configured to by pouring in B after molybdenum dioxide diluted hydrochloric acid dissolution；Will be miscible to single part or mixed ligand
Mixed serum D is configured in odium stearate.And under strong agitation or ul-trasonic irradiation, while by solution A and solution C by
It is added dropwise in mixed serum D and mixed serum E is configured to, ageing, suction filtration, filter cake is dried and obtain iron, molybdenum houghite；
Step 2：Iron, molybdenum houghite and DNPH are carried out dry ball milling, crosses 325 mesh sieves；
Step 3：By the screenings in step 2 and nanometer grade silica, conductive fine powder, calgon, powdered whiting,
Oyster shell whiting, Nano titanium dioxide and diatomite add dispersion in high speed dispersor；
Step 4：Step 3 gains are milled down to after regulation fineness, plant cellulose and quartz sand is added, after mixing,
Filter, discharge, you can.
In the present invention, prepare iron, molybdenum houghite first, then hydrotalcite is ground altogether with DNPH, make two
Person is sufficiently mixed, and then adds other raw materials, after use, can adsorb the formaldehyde of in the air by raw materials such as oyster shell whitings,
And formaldehyde just can be reacted with DNPH without the need for sour environment in the presence of iron, molybdenum class catalyst, so as to permanent
Elimination, react generate phenylhydrazone be yellow mercury oxide, in raw material add titanium dioxide, extraordinary bridging effect can be played, prevent
Only there is yellow spotting on Long-Time Service back wall.
The invention has benefit that：1st, the main component of coating of the present invention is the inorganic matters such as oyster shell whiting, during use, adopts
With aqueous solvent, organic solvent and macromolecule emulsion, Environmental Safety need not be added；2nd, the present invention add 2,4 dinitrophenyl hydrazine and
Iron, molybdenum houghite, can play extraordinary remove effect of formaldehyde, and effect is lasting；3rd, Nano titanium dioxide is added, rises
To extraordinary bridging effect, elegant in appearance, under illumination condition, electron transition can be produced, produce strong oxidizer and strong reduction
Agent, makes coating play antibacterial action；Well dispersed conducting powder, can effectively eliminate electromagnetic radiation.
