Nano STN mother liquor developed successfully

Coatings are one of the most widely used materials in the construction field. The application of high-tech nanomaterials in coatings has attracted more and more attention from the society, and it has already displayed attractive prospects, which has attracted widespread attention of people in the industry. Some paint companies have taken the lead in research and development, and a few companies have mass-produced nanomaterial modified coatings. "Nano" has become a new highlight of high-end, multi-functional, environmentally friendly coating products. Zhejiang Hongyu Material Science and Technology Co., Ltd. is one of its leading companies.
Researchers from Zhejiang Hongye Materials Science and Technology Co., Ltd. analyzed the current status of application of nanomaterials in the Chinese coating industry, focusing on practical problems, and combined Zhejiang Provincial Nanomaterials Application Engineering Technology Center, Zhoushan Grand Special Coatings Co., Ltd., and Zhoushan Mingri Nanomaterials Co., Ltd. The use of nano-SiOX and nano-TiO2 and other different nano-materials and their particle structure, physicochemical properties, the use of surfactants on the surface of the composite nano-particles graft modification, and zinc and calcium salts as the main antibacterial component, together with special far-infrared ( 8-18nm) radiation material, the composite nanopowder material is uniformly dispersed in the acrylic polymer system, and is stable. For the first time, an aqueous emulsion-nano-STN mother liquor, which has excellent properties such as nano-SiOx and nano-TiO2, and has a unique three-dimensional silica network structure with complementary nano-size geometric shapes, was first synthesized to effectively prevent nanoparticles during the coating modification application. The agglomeration due to the large specific surface area and surface tension can significantly improve the anti-aging properties of the coating, the pigment suspension stability, the color durability of the coating, the stain resistance and the coating film and the wall, under the condition of reducing or eliminating some additives. Many properties such as adhesive strength, but also can give the coating new features, such as hydrophobic, self-cleaning, antibacterial and so on.
As the nanomaterials used in the modified architectural coatings are generally TiO2, ZnO, SiO2, CaCO3 and other powder materials, these materials serve as a bridge between the macroscopic and microscopic particles, and they are well dispersed and matched when applied in coating modification. , can give the paint a lot of strange performance without a doubt. However, in actual production, the selection of nanomaterials, surface treatment technology, dispersion technology, dispersion process and other factors are all very critical, because these materials have a large specific surface area and surface tension, are easily adsorbed and agglomerate, and the agglomerated particles are in the emulsion. Dispersion is very difficult, and if it is not effectively dispersed, it will lose its proper modification effect.
Mr. Liu Jingchun, Chairman of Zhejiang Hongyu Material Science and Technology Co., Ltd. and Senior Engineer of the Chinese Academy of Sciences, introduced that the nano-STN mother liquor developed by the company has been mass-produced. The application of nano-STN mother liquor in architectural coatings does not require separate dispersion and no need to add equipment. It can be added directly to the emulsion in a stirring manner. Every coating company (regardless of the scale and technology level) can easily and effectively grasp and possess the nanometer modified coating production technology. Successfully solved the technical difficulties in the application of nano-materials in coatings, and provided new opportunities for low-cost filing, upgrading, and replacement of coating products. Since nano-modified coatings have optical properties, photoelectrocatalytic properties, peculiar selectivity, absorption characteristics, photoelectric conversion properties, etc. that are not available in the past, the use of them as additive for the four major components of coatings will undoubtedly change. The role of the paint itself. Therefore, people in the coatings industry have expressed their firm belief in and support for the application of nanomaterials in coatings.
