Abstract

An antifouling film is coated on a base, and contains a binder component, conductive particles, and a fluororesin. The conductive particles are bound together by the binder component; the binder component is closely bound to the base; and the antifouling film has a comprising the conductive particles of which surfaces are covered with the fluororesin.

Claims (24)

1. An antifouling film coated on a base, and comprising a binder component, conductive particles, and a fluororesin, wherein

the conductive particles are bound together by the binder component;

the binder component is closely bound to the base; and

the antifouling film has a surface comprising the conductive particles of which surfaces are covered with the fluororesin wherein

the fluororesin is made of a mixture of a fluoroethylene-vinyl ether alternating copolymer resin and a perfluoro alkyl group-ethylene oxide copolymer.

2. The antifouling film of claim 1 , wherein

the conductive particles are either carbon black particles or antimony-doped tin oxide particles.

3. The antifouling film of claim 1 , wherein

the conductive particles have a diameter of 10 nm to 100 nm.

4. An air blower blade having a surface coated with the antifouling film of claim 1 .

5. The air blower blade of claim 4 being made of a polypropylene resin.

6. An air blower comprising:

a motor; and

the air blower blade of claim 4 rotated by the motor.

7. An antifouling film coated on a base, and comprising a binder component, conductive particles, and a fluororesin, wherein

the conductive particles are bound together by the binder component;

the binder component is closely bound to the base; and

the antifouling film has a surface comprising the conductive particles of which surfaces are covered with the fluororesin wherein

the binder component is made of an unsaturated carboxylic acid-modified polyolefin resin.

8. The antifouling film of claim 7 , containing:

0.83 to 1.65 parts by weight of the conductive particles;

0.18 to 1.10 parts by weight of the fluororesin; and

1 part by weight of the unsaturated carboxylic acid-modified polyolefin resin.

9. An antifouling coating material for obtaining the antifouling film of claim 7 by applying the material to the base followed by drying, the material comprising a solvent containing the unsaturated carboxylic acid-modified polyolefin resin, the conductive particles, and the fluororesin.
