Plastic materials generally have high affinity for fats and oils, so that fats and oils are easily adsorbed, and the adsorbed fats and oils make it easier to adsorb dirt. This happens even in places that use a lot of water,
This process is followed even by exposure to dirt-poor water, and dirt accumulates. Also, when using soap or detergent,
Easy to get dirty. On the other hand, attempts have been made to reduce the surface energy so as to repel water containing dirt or to make dirt less likely to adhere.

Can be. As the acrylic resin, an acrylic polyurethane resin is particularly preferable. The acrylic polyol when using an acrylic polyurethane resin is not particularly limited. In addition, by using a thermosetting acrylic resin, an ultraviolet-curing acrylic resin, an electron beam-curing acrylic resin, and an air-drying acrylic resin, not only can it be used as a coating material, but also can be used as a tubular member by injection molding or other molding methods. A molded product such as a plate-like member can be easily formed.

When an acrylic polyurethane resin is used, a polyisocyanate compound is used as a crosslinking agent.
Examples of the polyisocyanate compound include aliphatic isocyanates such as non-yellowing hexamethylene diisocyanate (HMDI) and isophorone diisocyanate (IPDI).
And polyisocyanate compounds such as diphenylmethane 4,4'-diisocyanate (MDI) and hydrogenated MDI. HMDI is particularly preferred as the polyisocyanate compound.

Preferably, the O / OH ratio is between 0.8 and 1.5, especially between 1.0 and 1.2. When an acrylic polyurethane resin is used, a catalyst can be used at the time of crosslinking. As the catalyst, dibutyltin dilaurate is preferably used at an addition rate of about 0.005%, but is not limited thereto. When an acrylic polyurethane resin is used, it is preferable to perform heat treatment after film formation in order to promote curing. The heat treatment is preferably performed at 50 ° C. for 0.5 hours to 7 days.

The polyether-modified silicone is preferably a compound of a hydrophilic polyethylene oxide or polypropylene oxide alone or as a mixture of a polyether resin and a water-repellent silicone resin such as polydimethylsiloxane. Further, the polyether-modified silicone is a block copolymer of a polyether resin and a silicone resin, and is preferably linear. As a result, when added to the resin, not only the silicone resin but also a polyether resin which easily enters the resin appears on the surface. The surface thus formed has a feature that a hydrophilic portion and a water-repellent portion coexist. The substance used to obtain such a surface is not limited to this polyether-modified silicone. Many resins can be used as long as they are resins in which two types of resins having different surface energies are bonded, preferably resins that are linearly bonded.

When a side-chain polyether-modified silicone having a silicone resin as a main chain and a polyether resin formed in a side chain is added to the resin, it is less liable to stain than when no resin is added. Smears more easily than modified silicone. This is because polyether resin is less likely to appear on the surface of the side chain polyether-modified silicone.

When the polyether-modified silicone compound is added to the thermoplastic resin, it can be added during heating and kneading. As the thermoplastic resin, polyethylene,
Examples include polypropylene, polyvinyl chloride, and ABS resin.

When used in a bathtub, the polyether-modified silicone preferably has a silicone content of 15 to 80%. Preferably 15% to 50%
Is desirable. If it is less than 15%, the surface becomes excessive in polyether and silicone, and if it exceeds 80%, the surface becomes excessive in silicone and polyether, and the effect of suppressing the adhesion of dirt decreases.

The polyether-modified silicone compound is preferably contained in an amount of 0.01 to 10 parts by weight, more preferably 0.03 to 10 parts by weight, based on 100 parts of the solid content of the acrylic resin in the antifouling composition. It is preferably contained in an amount of 3 parts by weight, more preferably 0.1 to 3 parts by weight. When the amount is 0.01 part by weight or less, there is almost no difference between the case of no addition and the adhesion of dirt. On the other hand, when it is contained in an amount of 10 parts by weight or more, the strength and the water resistance of the coating film decrease. A feature of the present invention is that a high antifouling property can be realized by a low addition ratio to the resin component.

The above polyether-modified silicone compounds include those having a functional group such as an amino group, a hydroxyl group, a carboxyl group, a vinyl group, or a (meth) acryloyl group in the basic structure of Chemical formulas 1 and 2. . By including these functional groups, it can be bonded to the resin,
It is possible to extend the life of antifouling performance. For the introduction, there is a method using a prepolymer in which a methyl group in a silicone chain is substituted with, for example, an aminopropyl group or an aminoethylated aminopropyl group.

Specifically, for polyisocyanate, HMDI is more preferable than MDI. 7. The same effect can be obtained whether the polyether-modified silicone to be added to the acrylic polyurethane resin is linear or side chain, but the effect is higher when the linear chain is used. 8. The silicone content of the polyether-modified silicone added to the acrylic polyurethane resin is 15 to 80%
And more preferably 15 to 50%. 9. The thermosetting acrylic resin to which the polyether-modified silicone has been added should have little stain in the bathtub. 10. The epoxy resin to which the polyether-modified silicone has been added should have less adhesion of dirt in the bathtub. 11. The polyester resin to which the polyether-modified silicone has been added should have little adhesion of dirt in the bathtub. 12.
