Wherein, wetting agent can reduce surface tension or interfacial tension, and make water can more easily be deployed in solid materials surface and penetrate its surface and soaked, be the requisite auxiliary agent of coating.Wetting agent contains a large amount of solvents more, becomes one of source of VOC.The wetting agents of EW-10, HT100, EW-107 novel environment-friendly etc. are due to containing APEO and VOC, and have good surfactivity and wettability, are more and more applied to every field.Children's wall paint that the present invention proposes is selected the wetting agent of the acceptable environment-friendly type of coating industry, reduces the discharge of VOC.
Adding of dispersion agent can reduce jitter time, improves gloss, improves tinting strength and opacifying power, improves color developing and toning property, prevents flocculation and sedimentation.What the dispersion agent major part that coating is used was used belongs to negatively charged ion and non-ionic dispersing agent.In actual production, it is many that sodium salt dispersion agent and ammonium salt dispersion agent use.Ammonium salt dispersion agent water-tolerant, bad dispersibility; And sodium salt dispersion agent good dispersity, poor water resistance.Children's wall paint of the present invention, the characteristic of comprehensive evaluation dispersion agent, selects sodium salt dispersion agent.
The wetting agent that the present invention selects and dispersion agent all belong to tensio-active agent, easily bubble aborning, therefore need to add defoamer.Defoamer is of a great variety, can be divided into by composition: natural fats and oils, polyethers defoamer, higher alcohols, silicon class, polyether-modified silicon, novel self-emulsifying defoamer, polysiloxane defoamers etc.Children's wall paint of the present invention is selected acceptable defoamer in coating, and kind is not done requirement.
Titanium dioxide main component is titanium dioxide (T
io
2), be a kind of polycrystalline compounds, its particle becomes regularly arranged, has grid system.Titanium dioxide stable chemical nature, conventional in industry have anatase titanium dioxide (A type) and rutile-type (R) type.Titanium dioxide is considered at present the best a kind of white pigment of performance in the world, is widely used in the industries such as coating, plastics, papermaking, chemical fibre, makeup.Compared with other white pigments, titanium dioxide has superior whiteness, tinting strength, opacifying power, weathering resistance, thermotolerance and chemical stability.Children's wall paint of the present invention has added titanium dioxide, and product color is bright-coloured, and can amplified medium stability and paint film physical strength and sticking power, prevents crackle, prevents that ultraviolet ray and moisture from seeing through, and can extend coating work-ing life.
Thickening material mainly contains cellulose family, polyacrylate dispersion class and association type polyurethanes thickening material 3 classes.Cellulose family is few to formulation for coating material restriction, but stability is bad, and not only to paint flow, sex change exerts an influence polyurethanes, and and adjacent latex particle between exist and interact.Therefore children's wall paint thickening material cellulose family of the present invention and polyurethanes allotment are used, in production process, first add cellulose thickener, then add polyurethanes thickening material, give full play to the advantage of two kinds of thickening materials, strengthen product stability, improve product quality.
Photocatalyst is a kind of general name of the semiconductor material with photo-catalysis function, taking Nano titanium dioxide as representative.Photocatalyst is coated substrate surface, under the effect of light, can produce free hydroxy and active oxygen, dissociates to removing airborne flue dust in air, go mouldy, and improves Air quality.The photocatalyst airborne toxic and harmful of can also effectively degrading, as formaldehyde, benzene etc., effectively administers finishing pollution problem; Intestinal bacteria, streptococcus aureus, avian influenza virus etc. are all had to certain restraining effect, and the toxin of energy bacterium for degrading generation, purify air, improve habitation environment quality.Children's wall paint provided by the invention adopts clean taste paint liquid simultaneously, adds photocatalyst technology, greatly reduce product VOC content, there is the functions such as degraded toxic and harmful, antibacterial, deodorizing, mildew-resistant simultaneously, improve living environment Air quality, met the children's that Air quality is had relatively high expectations demand.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
