In formula system of the present invention, filmogen is the waterborne film-forming material, adopts 100% pure acrylic acid ester emulsion, and its paint film density is high, prevents that effectively contaminant infiltration is in the micropore kapillary of paint film.In addition, the solvent resistance of the paint film of pure acrylic acid ester emulsion is good, is difficult for swelling, removes easily with the most of watercolor pencil pollutent as dissolve medium such as alcohol.And common emulsion paint film can be caused pollutent to infiltrate by the spirit solvent swelling, not easy-clear.
The fluorine auxiliary agent that adopts in the formula system of the present invention is compared with hydrocarbon type traditional tensio-active agent; The F radius is littler than the C radius; Therefore the plain auxiliary agent of fluorine can more neatly be distributed in the interface closely; And can strengthen the interaction between polymer emulsion and the inorganic particle, more uniform sequential coated inorganic particle.The fluorine auxiliary agent can reduce surface tension, and the tensio-active agent of use 0.01%~0.1% can be reduced to the surface energy at interface below the 20dynes/cm, has strengthened the wettability of paint film on ground, and promotes the anti-performance of after-tacking.
Formula system of the present invention adopts the wax emulsion, the effect with hydrophobic and anti-adhesive, and the intensive hydrophobicity resists hydrophilic source of pollution and on paint film, sprawls infiltration, and the anti-adhesive properties of wax emulsion can make and adhere to is more easy-clear such as main pollutent such as wax crayon.
The glass powder that formula system of the present invention adopts can promote the hardness of paint film, reduces the scuffing of paintbrush to paint film, helps the persistent anti-graffiti function of paint film.Scribble source of pollution kind comprises children's watercolor pencil, wax crayon, colored pencil, ballpoint pen, ink, coffee, tomato-sauce, tea juice, footwear seal etc.
Aqueous anti-doodling paint of the present invention has good anti-soil and anti-graffiti function; VOC content wherein is 52~65g/L; Benzene series thing content is less than 300mg/kg, all well below the desired value of the volatile organic compounds of solvent-borne type product, and the suitable interior space that is used in.In addition, paint film of the present invention is fine and close, has the ability of impermeabilisation and reduction contamination adhesion simultaneously, is directed against children's watercolor pencil of children especially, wax crayon; Colored pencil, ballpoint pen, ink, coffee; Tomato-sauce, tea juice, materials such as footwear seal can be easily with the pollutent scrub.
