Antifouling film, air blower blade provided with same, air blower, and antifouling coating material
View Patent ↗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.
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.
