Nano-silica is a nano-leading product independently developed and produced by our company with controllable size, structure and specific surface area. It has small particle size, many micropores, large specific surface area, unsaturated residual state on the surface and many hydroxyl groups in different bonding states. and other characteristics. Products are divided into two categories: microporous type and spherical type according to their different particle structures. After transmission electron microscopy observation, nano-silica particles are small in size and narrow in particle size distribution. According to BET method test and analysis, nano-silica has a large specific surface area; Infrared spectrum analysis shows that there are a large number of hydroxyl groups and unsaturated residual bonds on the surface of nano-silica, which deviates from the steady-state silicon-oxygen structure. Tested using a Cary-5E spectrometer, nano-silica has a high sensitivity to ultraviolet light, long wavelength and visible light. The reflectivity; Omnisorp100CX specific surface and porosity analyzer measured that the surface of multi-microporous nano-silica contains many nano-scale micropores, and its porosity reaches 0.611ml/g. The company can also prepare a series of nano-silica products with different particle sizes, different specific surface areas and different processing forms according to user requirements. Adding it to many materials can improve the properties of the original materials and has broad application prospects in many industrial fields.

Application areas

　　1. Colloidal battery: The colloidal electrolyte prepared using nano-silica has the characteristics of high activity, strong acid-carrying and acid-locking capabilities, and the multi-dimensional network structure of the colloid, which has a strong effect on improving battery defects. The filled gel battery has unique advantages such as large capacity, increased number of stress cycles, small water loss and self-discharge rate; no acid mist gas precipitation, no electrolyte overflow and stratification phenomenon; wide application environment; and can effectively improve the battery performance. Improve product stability and yield, and reduce product repair and return rates.

　　2. Coating: On the basis of the original formula of water-based latex paint, after adding 0.3-1% of the total weight of nano-silica (need to be fully dispersed), its suspension stability, thixotropy, bonding strength between the coating and the substrate, Properties such as smoothness are improved, drying time is shortened, artificially accelerated UV aging test time is increased, and the stain resistance of the coating is also improved.

　　3. Plastics: Nano-silica is dispersed in plastic raw materials such as polypropylene (PP) and polyvinyl chloride (PVC), which can greatly improve the strength, toughness, wear resistance and aging resistance of plastic products.

　　4. Adhesive: Nano-silica is used in adhesives, which can greatly improve the bonding strength.

　　5. Rubber: Add a small amount of nano-silica (replacing carbon black) to solution-polymerized styrene-butadiene and other rubbers as a reinforcing agent and anti-aging agent. The toughness, strength, elongation, flexural resistance and resistance of the rubber products produced will be improved. Aging and other properties are improved.

　　6. Inkjet printing and photo paper: Adding nano-silica to inkjet printing can improve the layering of printing tones, reduce the drying time of ink, and improve the waterproof performance of coating materials;

　 7. Insulating materials: Adding nano-oxide to epoxy resin insulating materials can increase the bonding performance, toughness, and strength of the product;

　　In addition, nano-silica can also be widely used in the upgrading of products in textiles, ceramics (enamel), gypsum, pigments, adhesives, cosmetics, fiberglass, chemical fibers, non-inorganic glass, environmental protection and many other fields.

Instructions for use

　　Disperse the product directly into the system through mechanical dispersion or ball milling; or disperse the product in non-inorganic solvents such as acetone, ethanol and then add it to the system. The recommended addition amount is 0.1-2% by weight. Individual product systems can reach more than 10%, which depends on the actual application.
