Hydrophobic nano-silica hardener and wear-resistant agent

Product Type Hydrophobic Nano Silica Hardener Wear Resistant Agent Model
Product Introduction
Hydrophobic ultrafine silica powder is powdered using special imported additives and processes based on the chemical properties of different matrix materials. The body is made by surface modification in situ. Hydrophobic ultrafine silica powder has better interfacial compatibility with the base material resin, can be evenly dispersed in the base material resin, and forms a tight combination with the polymer system to comprehensively improve the performance of the polymer material.
Product Features
The resin has good interfacial compatibility and resists agglomeration, which improves the decline in mechanical properties of composite materials caused by high filling.
Special surface treatment, self-flowing powder is beneficial to dispersion under shear, reduces the viscosity of the resin blend, and optimizes processing performance.
High temperature and low thermal expansion coefficient reduce the thermal expansion coefficient and curing molding shrinkage of composite materials, increase the thermal deformation temperature of polymers and product dimensional stability, alleviate the internal stress concentration of composite materials, and improve mechanical properties.
The excellent electrical insulation fluidization purification process greatly reduces the impurity ion content, making the composite material have good insulation properties and arc resistance properties, and reduces the water absorption rate of the solidified product.
High strength improves the hardness, strength and wear resistance of composite materials, but attention must be paid to the wear and tear on equipment. It is recommended to carefully adjust the equipment operating parameters.
It has excellent weather resistance and migration resistance and is completely chemically inert. It will not change or induce deterioration in the presence of catalysts or multi-component systems, and will not decompose.

Instructions for use
Single use should be selected according to the performance requirements of the product , the particle size is closely related to the performance of the composite material. The smaller the particle size, the better the surface fineness and the more significant the enhancement effect, but the viscosity will also be greater during blending. Please carefully adjust the formula to balance various properties.
Use Mixed filling of different particle sizes can form dense filling in the polymer system at appropriate proportions. A reasonable compound system can avoid the settling or floating of the filler, while reducing the viscosity of the resin blend under equal filling, which is beneficial to shear dispersion. .
After silicon crystal powder is ultrafine, due to the increase in specific surface area, it is easy to agglomerate, has poor compatibility with polymers, and is difficult to disperse evenly, affecting the physical properties of composite materials. The relationship between hydrophobic micro-silica crystal powder and polymers The interface compatibility is good, and the surface coating layer can produce a bonding reaction with the groups of the base resin, reducing the viscosity of the blend, eliminating interface stress concentration, and improving the mechanical properties of the composite material. Different types of hydrophobic products have different surface groups due to Different resin systems have slightly different applicability. It is recommended to carefully evaluate or contact our company.
It is recommended to determine the optimal addition amount through experiments.
