Description
技术领域technical field
本发明涉及一种包含水溶性盐、表面活性剂和糖醇的含水防污染涂布组合物，以及具有使用该组合物形成的防污染涂层的制品。The present invention relates to an aqueous antifouling coating composition comprising a water-soluble salt, a surfactant, and a sugar alcohol, and articles having an antifouling coating formed using the composition.
背景技术Background technique
为了防止污染物附着到玻璃或其它底材的表面上，已经提出了一种在其上形成水溶性盐涂层薄膜的方法，然后，当需要时，通过用水洗涤涂层和污染物来清洁表面(参见日本专利申请公开第11-35343号)。但是，当只对底材表面施涂水溶性盐时，涂层变得不平并且令人不满意地给出不好的性能特征，尤其是在高温下处理所涂布的底材时。In order to prevent pollutants from adhering to the surface of glass or other substrates, a method has been proposed to form a water-soluble salt coating film thereon, and then, when necessary, clean the surface by washing the coating and pollutants with water (See Japanese Patent Application Laid-Open No. 11-35343). However, when only water-soluble salts are applied to the surface of the substrate, the coating becomes uneven and unsatisfactorily gives poor performance characteristics, especially when the coated substrate is processed at high temperatures.
另一方面，日本专利申请公开第2000-211947号公开了一种使用阴离子型表面活性剂水溶液获得的水溶性保护薄膜。但是，难以控制表面活性剂层的厚度，该表面活性剂层在处理期间容易受到损伤。On the other hand, Japanese Patent Application Laid-Open No. 2000-211947 discloses a water-soluble protective film obtained using an aqueous solution of an anionic surfactant. However, it is difficult to control the thickness of the surfactant layer, which is easily damaged during handling.
发明内容Contents of the invention
因此，本发明的首要目的是提供一种具有改良的涂布和润湿性质的防污染涂布组合物。It is therefore a primary object of the present invention to provide an antifouling coating composition having improved coating and wetting properties.
根据本发明的一个方面，提供了一种包含水溶性盐、表面活性剂和糖醇的含水防污染涂布组合物。According to one aspect of the present invention, there is provided an aqueous antifouling coating composition comprising a water-soluble salt, a surfactant and a sugar alcohol.
根据本发明的另一个方面，提供了一种具有使用所述防污染涂布组合物形成的防污染涂层的制品。According to another aspect of the present invention, there is provided an article having an antifouling coating formed using the antifouling coating composition.
具体实施方式Detailed ways
本发明的含水防污染涂布组合物包含水溶性盐、表面活性剂和糖醇。The aqueous antifouling coating composition of the present invention comprises a water-soluble salt, a surfactant and a sugar alcohol.
可以用于本发明的防污染涂布组合物的水溶性盐的实例包括碱金属碳酸盐、碳酸氢盐、硝酸盐、硫酸盐、磷酸盐、硅酸盐、硼酸盐、有机酸盐以及它们的复盐，优选是四硼酸钠(Na2B4O7)。优选地，水溶性盐的用量可以为组合物量的0.01～1％(重量)。如果水溶性盐的含量低于0.01％(重量)，那么涂层的强度变弱，而如果其高于1％(重量)，则在表面上可能形成盐晶体。Examples of water-soluble salts that can be used in the antifouling coating composition of the present invention include alkali metal carbonates, bicarbonates, nitrates, sulfates, phosphates, silicates, borates, organic acid salts, and Their double salts are preferably sodium tetraborate (Na 2 B 4 O 7 ). Preferably, the water-soluble salt may be used in an amount of 0.01-1% by weight of the composition. If the content of the water-soluble salt is less than 0.01% by weight, the strength of the coating becomes weak, while if it is more than 1% by weight, salt crystals may form on the surface.
用于本发明的防污染涂布组合物的表面活性剂可以是阴离子型表面活性剂或非离子型表面活性剂，它们的实例包括直链烷基磺酸钠、直链烷基苯磺酸钠、聚乙烯基磺酸钠、聚丙烯酸钠、聚甲基丙烯酸钠、聚乙二醇、聚乙烯醇等。表面活性剂改善涂层溶液的湿润性质。优选地，表面活性剂的用量为组合物量的0.0001～1％(重量)。如果表面活性剂的含量低于0.0001％(重量)，导致湿润性差，而如果其高于1％(重量)，则涂布变差。The surfactant used in the anti-pollution coating composition of the present invention may be an anionic surfactant or a nonionic surfactant, and examples thereof include sodium linear alkyl sulfonate, sodium linear alkyl benzene sulfonate , Sodium polyvinyl sulfonate, Sodium polyacrylate, Sodium polymethacrylate, Polyethylene glycol, Polyvinyl alcohol, etc. Surfactants improve the wetting properties of coating solutions. Preferably, the surfactant is used in an amount of 0.0001 to 1% by weight of the composition. If the content of the surfactant is less than 0.0001% by weight, poor wettability results, while if it exceeds 1% by weight, coating becomes poor.
用于本发明的防污染涂布组合物的糖醇可以是选自山梨糖醇、木糖醇和甘露糖醇的单糖或多糖衍生物，优选是甘露糖醇。通过调节糖醇的量可以控制涂层的厚度。优选地，糖醇的用量为组合物量的0.01～5％(重量)。如果糖醇的含量低于0.01％(重量)，则涂层变得太薄，而如果其高于5％(重量)，则导致涂布差。The sugar alcohol used in the anti-pollution coating composition of the present invention may be a monosaccharide or polysaccharide derivative selected from sorbitol, xylitol and mannitol, preferably mannitol. The thickness of the coating can be controlled by adjusting the amount of sugar alcohol. Preferably, the sugar alcohol is used in an amount of 0.01-5% by weight of the composition. If the content of sugar alcohol is less than 0.01% by weight, the coating becomes too thin, while if it is more than 5% by weight, poor coating results.
优选地，基于组合物的总重量，本发明的防污染涂布组合物包含0.01～1％(重量)的水溶性盐、0.0001～1％(重量)的表面活性剂，以及0.01～5％(重量)的糖醇。Preferably, based on the total weight of the composition, the antipollution coating composition of the present invention comprises 0.01 to 1% by weight of a water-soluble salt, 0.0001 to 1% by weight of a surfactant, and 0.01 to 5% ( weight) of sugar alcohols.
可以将本发明的防污染涂布组合物施涂于各种底材。底材的实例优选地包括玻璃、树脂、陶瓷、金属材料和其它材料，优选是玻璃底材。The antifouling coating composition of the present invention can be applied to various substrates. Examples of the substrate preferably include glass, resin, ceramics, metallic materials and other materials, preferably a glass substrate.
可以使用常规涂布方法，如浸涂、喷涂、流涂或摩擦而将本发明的防污染涂布组合物施涂于底材。The antifouling coating composition of the present invention can be applied to a substrate using conventional coating methods such as dipping, spraying, flow coating or rubbing.
通过施涂本发明的涂布组合物形成的涂层的厚度优选为600至5000，更优选为700至4000。The thickness of the coating layer formed by applying the coating composition of the present invention is preferably 600 to 5000 Å, more preferably 700 to 4000 Å.
底材上的涂层可以通过用水洗涤除去。表面涂层上的污垢、灰尘、湿气或其它污染物可以与涂层一起从底材表面被洗去。优选地，通过浸入清洗水浴中、在超声装置中清洗、高压流喷雾等来进行这种洗涤。The coating on the substrate can be removed by washing with water. Dirt, dust, moisture or other contaminants on the surface coating can be washed from the substrate surface along with the coating. Preferably, such washing is performed by immersion in a washing water bath, washing in an ultrasonic device, spraying with a high-pressure stream, or the like.
本发明的防污染涂布组合物包含改善涂布性质的表面活性剂和形成网络结构的糖醇，以及水溶性盐，因此提供了一种在水中表现出高溶解性的厚涂层。这种厚涂层既使在所涂布的底材经历高温时也不会受到损伤。The antifouling coating composition of the present invention contains a surfactant for improving coating properties and a sugar alcohol for forming a network structure, and a water-soluble salt, thereby providing a thick coating exhibiting high solubility in water. This thick coating will not be damaged even when the coated substrate is subjected to high temperature.
本发明将在实施例中进行进一步的描述和说明，但是这些实施例并不限制本发明的范围。The present invention will be further described and illustrated in examples, but these examples do not limit the scope of the present invention.
