り、しかも、結露水滴は大きくなりやすい。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a surface modification method for improving dew condensation on plastic surfaces. For this reason, plastic molded products (films, sheets, synthetic fibers, etc.) and plastic coating materials (painted steel plates, laminated steel plates, etc.) have a low affinity with water and are easily exposed to the surface when the outside air drops below the dew point. Condensation occurs, and the condensed water droplets tend to grow large.

Since the adhesion of the anti-condensation agent is low and the anti-condensation effect decreases over time, it is not possible to prevent condensation during the drying period.

ることにより結露防止性を付与した。(Means for Solving the Problems) In the present invention, a monomer having ion exchange ability is graft-polymerized onto a plastic surface to modify the surface to be hydrophilic and water absorbent. That is, after coating a plastic surface with a hexamer having a carboxyl group, a sulfone group, or both of these functional groups and an ethylenically unsaturated double bond, an electron beam is irradiated to form a -1:/mer on the plastic. Graft polymerization was performed on the surface, and the surface was washed and then treated with alkali to impart anti-condensation properties.

次のように置換される。When a monomer having the above-mentioned functional groups and double bonds is applied to plastic and irradiated with an electron beam, the ethylenic double bonds of the monomer react with the plastic and graft polymerize to the surface, forming carboxyl groups and sulfone groups.

Therefore, when the surface of this film is treated with alkaline water T8 liquid or gas, the hydrogen or hydroxyl group of the carboxyl group or sulfone group is replaced by the alkali as follows.

Since dew condensation water is difficult to form into water droplets and parent wood groups are also present in the covered surface layer, water on the surface is absorbed and stored inside the surface layer.

Although it depends on known coating methods such as roll coating and dipping, electron beam irradiation after coating is used to prevent plastic deterioration.
It is preferable to set it to 0.5 to 20 Mrad.Even if the plastic is irradiated with an electron beam, monomers and homopolymers that do not polymerize remain in the plastic, but these are removed by washing with water or the like.
