Abstract

The invention discloses a method for processing a surface of a hollow glass microsphere. The method comprises the steps of: mixing silicane surfactant with ethanol in a volume ratio of 1:(7-11) to form a modifying solvent; placing the hollow glass microsphere in the modifying solvent; keeping the temperature at 20-30 degrees centigrade; stirring for 10min by a speed of 60rpm, then ultrasonically vibrating for 5min; filtering the hollow glass microsphere by a 1000-mesh filter net; placing in an oven, increasing the temperature to 100-150 degrees centigrade; and reacting for 60min to obtain the surface modified hollow glass microsphere. After the surface treatment is carried out by the method disclosed by the invention, the hollow glass microsphere can be directly added into a high molecular polymer base body as an additive for improving the performance of a composite material and increasing the practical application value of the composite material.

Description

technical field [0001] The invention relates to the field of glass materials, in particular to a method for treating the surface of hollow glass microspheres. Background technique [0002] Hollow glass microspheres are spherical, isotropic, and have uniform stress and strain. Due to the characteristics of light specific gravity, large specific surface area, flame retardancy, high thermal temperature, good rigidity and strength, and corrosion resistance, the product can be used in plastics, coatings, It can be used as a reinforcing functional filler in the fields of paint ink, ceramics, packaging materials, floor adhesives, oil drilling, etc., which can not only effectively improve product performance or construction effect, but also significantly reduce production costs. Therefore, it has huge market potential and broad market potential. application prospects. At present, most of the research on the application of hollow glass microspheres is just to use hollow glass micros...
