Abstract

PROBLEM TO BE SOLVED: To convert condensation water drops into a water film to thereby decrease the amount of water drops dripping from the ceiling of a bathroom by forming the ceiling from a highly hydrophilic resin member having hydrophilic groups on its surface. SOLUTION: The surface hydrophilicity of the highly hydrophilic resin member is achieved preferably by introducing at least one kind of hydrophilic groups selected from among -SO3H, -SO3M, -OSO3M, -COOM, -NR3X, -COOH, -CO, -NH2, -CN,-OH, -NHCONH2, and -(OCH2CH2)n groups into the surface thereof. In these groups, R is an alkyl; M is an alkali metal or NH4; and X isahalogen. The hydrophilic groups are introduced preferably by a corona treatment, a plasma treatment, or a treatment with a gas mixture of fluorine and oxygen. Preferably, the highly hydrophilic resin member having hydrophilic groups introduced into the surface thereof has a contact angle of water of 40 deg. or lower. Preferably, the highly hydrophilic resin is based on a resin such as a polyolefin resin, an (un)saturated polyester resin, a PS resin, an ABS resin, an AS resin, a polyacetal resin, or a polycarbonate resin.

2. Description of the Related Art Steam is condensed on the ceiling of a bathroom and water drops adhere to the ceiling, and eventually grow and fall. Especially in winter, dew condensation is easy and water drops are cold, so it is very uncomfortable when dropped on the body. Numerous methods have been devised to solve such problems. For example, an inorganic porous material such as zeolite is coated with a cement or resin binder to keep the water in the porous material, making it harder for the condensed water drops to fall, or adding a surfactant to the resin to prevent dew condensation. There is a way to have sex.

According to a fourth aspect of the present invention, a hydrophilic group is introduced into the surface of the resin during the corona treatment step. Since it is introduced during the corona treatment process, carboxyl groups -COOH, carbonyl groups -CO, and hydroxyl groups -OH having high hydrophilicity are generated on the resin surface, and the wettability is further improved and the attached water is removed by water droplets. Instead, it forms a water film. The formation of a water film increases the surface area and facilitates drying. Further, a smoother surface can be obtained.
As a result, there is no problem that mold spores adhere to a rough surface such as a porous body and mold easily grows with the adsorbed moisture. In addition, since the hydrophilic functional group reacts and is fixed on the surface of the base resin, it does not come off as in the surfactant mixing method, and there is no problem that the duration is short.
