    • PROBLEM TO BE SOLVED: To further extend the application field of silica nano hollow particles and make the use of them easier by preventing the cohesion of the silica nano hollow particles for dispersing them as micro-aggregated particles with an organic synthetic resin and enabling the mixing of them by a larger amount as a solid part in a hollow particle-containing master batch.
      SOLUTION: The hollow particles are prepared by (S10) blending the silica nano hollow particles 1 with ethanol and a modified silicone oil as a surface-modifying agent, (S11) agitating and dispersing by using a high speed agitator, (S12) dispersing huge aggregated particles aggregated to approximately 5 μm particle diameter and then filtered by using a sieve, and then (S13) dispersing by using a wet type jet mill strongly to make the micro-aggregated particles having approximately ≤0.5 μm particle diameter. The hollow particle-containing master batch 10 is produced by (S17) heating and kneading the dispersive silica nano hollow particles 5 prepared by further passing through three processes with the organic synthetic resin 6, (S18) extrusion molding and (S19) pelletizing.

    • PROBLEM TO BE SOLVED: To enhance the surface hardness of a coating film and to certainly prevent the damage of the coating film without losing the original quality feeling or feel of a base material by the heat insulating properties, abrasion resistance, high hardness and transparency of hollow particles consisting of a silica shell. SOLUTION: Since the coating film 3A is formed along the surface unevenness of a Japanese cypress board 2 and this coating film 3A containing the hollow particles 4 consisting of the silica shell has no gloss, the Japanese cypress brand 1 having the coating film 3A formed on its surface is not changed in its appearance and feel and the abrasion resistance of the board 2 as wood can be enhanced by the abrasion resistance and high hardness of the hollow particles 4 consisting of the silica shell. Further, by forming the coating film 3A on the surface of the board 2, the fire retardancy of the board 2 can be enhanced by the heat insulating properties of the hollow particles 4 consisting of the silica shell. Since the appearance (quality feeling) and feel of the board 2 are not changed, the high grade feeling of the board 2 is not damaged. COPYRIGHT: (C)2008,JPO&INPIT
