摘要: Inorganic fillers such as silica balloons are used as a lightweight filler for resin moldings. But the specific gravity of these inorganic fillers is about 0.2 at most, so that there is a limit to reduction in weight. The foamed product of organic polymers is obtained as a lightweight substance, but it is hardly put to practical use because of its poor solvent resistance and thermal resistance.The microballoon of the present invention is produced by coating the surface of a hollow particle having the wall film of a thermoplastic high polymer with a thermosetting resin.The present invention provides a microballoon having excellent solvent resistance and thermal resistance as well as a very low specific gravity, and said microballoon is useful as a lightweight filler for resin moldings, aggregate for FRP, ingredient for paints, and the like.

The hollow resin particles include a thermoplastic resin shell and a hollow part surrounded by the shell. The thermoplastic resin is a polymer produced from a polymerizable component containing 0.6 to 3.0 wt % of a crosslinkable monomer having at least two polymerizable carbon-carbon double bonds per molecule and 97 to 99.4 wt % of an uncrosslinkable monomer having one polymerizable carbon-carbon double bond per molecule. A blowing agent is encapsulated in the hollow resin particles. The blowing agent contains 50 to 100 wt % of an organic compound having a vapor pressure higher than 100 kPa at 25° C. Further, the encapsulation ratio of the blowing agent ranges from 3 to 13 wt % of the hollow resin particles.
