Based on above-mentioned, the coconut palm dimension charcoal Lysimachia foenum-graecum is compound except methanal paint includes the raw material of following parts by weight：Styrene-acrylic emulsion
60~70, quartz sand 13~15, Pigment white 10~12, powdered whiting 14~16, kaolin 5~7, nano-titanium colloidal sol 1.3~
1.7, calcium aluminate 0.7~0.9, melmac 0.7~0.9, nano carbon sol 0.7~0.9, diatomite 0.7~0.9, coconut palm
Tie up charcoal 2.3~2.7, lignin 0.5~0.7, Lysimachia foenum-graecum powder 0.2~0.4, long oil alkyd 0.5~0.7, antifoaming agent 0.7
~1, polyamide wax 0.5~0.8, manganese naphthenate 0.3~0.5, propandiol butyl ether 24~28, water 30~34.
Based on above-mentioned, the antifoaming agent is polyethers antifoaming agent, emulsification dimethicone or dimethyl silicone polymer.
The present invention also provides a kind of compound preparation methods for removing methanal paint of above-mentioned coconut palm dimension charcoal Lysimachia foenum-graecum comprising walks below
Suddenly：
Under the action of ultrasonic agitation, nano-titanium colloidal sol, nano carbon sol, propandiol butyl ether and water are homogenously mixed together,
Obtain solvent mixed liquor；
By quartz sand, Pigment white, powdered whiting, kaolin, melmac, calcium aluminate, diatomite, coconut palm dimension charcoal, wooden
Element, Lysimachia foenum-graecum powder, long oil alkyd, polyamide wax and manganese naphthenate uniformly mix, and obtain solid material mixture；
In the case where the churned mechanically collective effect with 2500~3000 r/min is stirred by ultrasonic, styrene-acrylic emulsion, the solvent are mixed
Close object, material mixture and the antifoaming agent admittedly mix, and stir 30~40 min.
In the coconut palm dimension compound raw material except methanal paint of charcoal Lysimachia foenum-graecum provided by the invention, the nano-titanium colloidal sol tool
There are stronger photocatalytic, bigger specific surface area, stronger chemical bonding adsorptivity, electrically charged hydroxyl, high table
The advantages that face is active, so it can remove formaldehyde, purification air, antibacterial and mouldproof, deodorization, extremely strong anti-pollution, automatic cleaning action.
In addition, the nano-titanium colloidal sol also has the effects that increase coating intensity, adhesion strength, wearability, so it is with relatively good
Film forming, and it is smooth to form a film, and improves coating scrubbing resistant performance.
Diatomite has many advantages, such as that porosity is big, absorbability is strong, chemical property is stable, wear-resisting, heat-resisting；It can also be by water
Molecule resolves into negative ions, since hydrone is wrapped, negative ions group is formed, then using hydrone as carrier, in air
In swim everywhere, possess sterilizing ability.The negative ions to swim can be to formaldehyde, the anaphylaxis substance and other are thin in environment
The harmful substances such as bacterium, mould are surrounded and are isolated, and the most active hydroxide ion of performance and formaldehyde in negative ions group
Etc. harmful substances carry out violent chemical reaction, they are completely decomposed into the harmless objects such as hydrone.
Soluble solids in the nano carbon sol is that mass percentage is 10%~15%, carbon granules diameter 10~100 therein
Nm is in spherical dispersion, has great specific surface area and high specific surface energy, surface Selective adsorption, excellent conduction
Property；With quantum size effect and macroscopic quantum channel effect；With excellent environmental stability, still have under the high temperature conditions
The singularitys such as high-strength, high-ductility；Hydrophily is extremely strong, and dispersibility in water is fabulous, stores 3 years do not roll into a ball at normal temperatures and pressures
It is poly-.
Coconut palm dimension charcoal be using coconut husk as raw material, through high-temperature activation, carbonization treatment, at the same load photocatalyst, carbon fiber and
At a kind of novel absorbent charcoal；It has flourishing specific surface area, abundant micropore diameter, specific surface area up to 1000~
1600m2/ g, micro pore volume 90% or so, micropore size are 10A~40A, so, coconut palm, which ties up charcoal, has large specific surface area, aperture
It is moderate, be evenly distributed, the advantages that adsorption rate is fast, impurity is few, the pernicious gases such as PARA FORMALDEHYDE PRILLS(91,95), benzene, TVOC have stronger absorption work
With.
Manganese naphthenate removes formaldehyde environmental protection coating material in use described in can promoting, and coating quickly urges dry film forming.
Therefore, compared with prior art, the present invention is using nano carbon sol, diatomite, powdered whiting, kaolin, aluminium
Sour calcium and the coconut palm dimension cooperation nano-titanium colloidal sol such as charcoal, enhance the intensity of TiO 2 sol, bactericidal properties, adsorbance, corrosion resistance and
The performance of heat resistance etc., enhances adsorption capacity and adsorption rate, has good adsorption effect to tiny field trash,
Expand adsorption range；Diatomite and nano-titanium colloidal sol arrange in pairs or groups coconut palm dimension charcoal again and Lysimachia foenum-graecum powder uses, and can also have with formaldehyde etc.
Evil substance chemically reacts, to achieve the purpose that remove formaldehyde；So the coconut palm dimension charcoal Lysimachia foenum-graecum provided by the invention is compound
Except methanal paint PARA FORMALDEHYDE PRILLS(91,95) adsorption rate is fast, Adsorption effect is good, and depollution of environment rate is high, environmentally protective, good film-forming property；This hair
The coconut palm dimension charcoal Lysimachia foenum-graecum of bright preparation is compound to have good removal effect, especially PARA FORMALDEHYDE PRILLS(91,95) except methanal paint to various pollutants
Removal effect is high, and preparation method is simple, and operability is strong, at low cost, is conducive to promote and apply.
