It is obtained by chemically bonding a silane-based surfactant having a chlorosilyl group or an alkoxysilyl group.
【０００５】人工大理石表面が微細な凹凸を有している
場合、次のWenzelの式が成立する。[0005] When the artificial marble surface has fine irregularities, the following Wenzel's equation holds.

And the affinity with the dirt component is reduced, so that the antifouling property is greatly improved. In addition, bacteria and molds are also less likely to adhere to their prey, so that their growth is suppressed.

用上剥離しない耐久性に優れた撥水撥油効果を発揮でき
る作用もある。On the surface of the artificial marble, the water repellency of the surface of the artificial marble is increased due to a synergistic effect of fine irregularities and a decrease in surface free energy due to the chemical bonding of the silane-based surfactant to the substrate of the artificial marble. It improves the anti-fouling property by reducing the activity to the dirt component. Furthermore, since the adhesion of the dirt component to the surface of the artificial marble is reduced, it is possible to suppress the growth of bacteria and mold that feed on them. Since the surfactant is integrated with the artificial marble base material, it also has an effect of exhibiting a water-repellent and oil-repellent effect having excellent durability that does not practically peel off.

By not exceeding m, the greater the true surface area of the artificial marble, the greater the synergistic effect with the surfactant, the higher the water repellency of the surface of the artificial marble, and the lower the affinity for dirt components I do. Furthermore, since the adhesion of the dirt components to the surface of the artificial marble is greatly reduced, the growth of bacteria and molds that feed on them is greatly suppressed.

ラン系界面活性剤は必要最小限の量でよい。In this case, the silane-based surfactant chemically bonds to the hydroxyl group of water (H 2 O) adsorbed on the surface of the inorganic filler. For this reason, since the silane-based surfactant is bonded only to the surface layer of the artificial marble, the physical properties and appearance of the artificial marble are not impaired, and the silane-based surfactant is required in a minimum necessary amount. .

In addition, by containing an organic antibacterial agent, growth of mold is mainly suppressed. A small amount of inorganic and organic antibacterial agents are added because the fine irregularities on the surface of the artificial marble and the synergistic effect of the chemically bonded surfactant reduce the adhesion of dirt components that feed on bacteria and mold. Has sufficient antibacterial and antifungal effects. Therefore, the influence on the physical and chemical properties of the artificial marble is small, and the properties of the artificial marble can be sufficiently exhibited.

A chemically adsorbed solution in which (CH 2 ) 15 SiCl 3 is dissolved at a concentration of about 2 × 10 −3 to 5 × 10 −2 mol is prepared, and the artificial marble substrate 1 is immersed at room temperature for about 1 hour. In this case, the artificial marble substrate 1 does not necessarily need to be immersed in the chemical adsorption liquid, but may be applied or sprayed to bring the chemical adsorption liquid and the artificial marble substrate 1 into contact. Because the artificial marble surface as shown in FIG. 1, -OH groups of the water adsorbed on aluminum hydroxide and glass fibers are added to and blended as an inorganic filler (H 2 O), etc. are exposed, The chlorosilyl group of the chlorosilane-based surfactant reacts with the -OH group to form a bond represented by Chemical Formula 1 on the surface, and a single molecule curtain is formed on the surface of the artificial marble base material as shown in FIG. Thus, it can be formed in a state chemically bonded via oxygen.

る細菌やカビの増殖も抑制される。By forming fine irregularities on the surface of the artificial marble,
Adsorption reaction of chlorosilane- or alkoxylan-based surfactants causes covalent bonding at the artificial marble substrate interface, resulting in an artificial effect due to the synergistic effect of fine irregularities and a decrease in surface free energy due to the silane-based surfactants. The marble surface has the effect of providing an artificial marble having excellent water and oil repellency, high antifouling properties, and excellent durability in which the silane-based surfactant is practically not peeled off. Furthermore, since the adhesion of the dirt component to the surface of the artificial marble is reduced, the growth of bacteria and mold that feed on them is suppressed.

By not exceeding m, the true surface area of the artificial marble will increase dramatically. As a result, the synergistic effect with the reduction of surface free energy by the silane-based surfactant increases, the water / oil repellency of the surface of the artificial marble improves, the affinity with the dirt component decreases, and the adhesion decreases. Increases antifouling properties.
