Description
Technical Field
The invention relates to a nano water dispersion of organic-inorganic composite hybrid silica formed by mixing and hybridizing a nano silicon dioxide water dispersion and a bio-based acrylic emulsion. The organic-inorganic hybrid nano-silica dispersion can be used as a finishing coat to be coated on the surface of building coating, and has the effects of improving surface tension, reducing water contact angle of a paint film, improving contamination resistance, surface hardness and wear resistance.
Background
The bio-based acrylic emulsion is polymerized by adopting a fermentation product of natural biological raw materials. The natural biological raw materials are used as renewable substances to replace non-renewable petroleum product raw materials, so that the dependence on petroleum is reduced, the low-carbon emission is realized, the greenhouse effect is reduced, and the sustainable development of the coating industry is promoted. The emulsion has ultra-low VOC and ultra-low odor, and can pass the biological product certification of USDA of the United states department of agriculture.
Compared with organic paint base material, the nano silicon dioxide water dispersion liquid has less environmental pollution in the production and use processes, and the product takes water as a dispersion medium, and particularly has no adverse effects on the aspects of environment and health in the film forming process. The raw materials for producing the nano-silica aqueous dispersion are sandstone natural inorganic silicate minerals which are rich in sources and can be obtained at will, and the use of the nano-silica aqueous dispersion inorganic film forming material can reduce the dosage of bio-based acrylic emulsion in a coating formula, so that the dependence on petroleum is further reduced, the low-carbon emission is realized, and the greenhouse effect is reduced.
Because the bio-based acrylic emulsion product is environment-friendly and low in emission, in order to reduce the using amount of the film forming aid or not use the film forming aid in use, the hardness of the bio-based acrylic polymer is designed to be low, the strength of a coating film is poor, the surface is slightly sticky, and the stain resistance is poor. When the nano silicon dioxide aqueous dispersion inorganic film forming material is used for forming a film, the hardness of the film forming additive is not required to be good, but the problem that the film is poor in flexibility and easy to crack exists.
Therefore, the bio-based acrylic emulsion and the nano-silica aqueous dispersion inorganic film forming material are compounded into the inorganic nano-silica hybrid bio-based acrylic emulsion super-hydrophilic surface finish paint according to a proper proportion, the acrylic emulsion particles and the nano-silica particles are hybridized into a super-hydrophilic coating film with certain strength, cracking resistance and toughness and rich silicon hydroxyl groups on the surface due to osmotic pressure formed by water volatilization during film forming of the finish paint, and the transparent finish coating film has good stain resistance and easy cleaning performance.
