Embodiment

[0158] Hereinafter, the present invention will be specifically described with reference to examples, but the present invention is not limited to these examples. In addition, Examples 1-4 and 6-9 are examples, and Example 5 and Example 10 are comparative examples.

[0159] The porous inorganic fine particles used in Examples and Comparative Examples, and the functional articles obtained in Examples and Comparative Examples were evaluated as follows.

[0160] [Porous inorganic fine particles]

[0161] The average primary particle diameter is to randomly extract 200 particles from the image obtained by shooting the porous inorganic fine particle sol with a transmission electron microscope: JEM-1230 (JEOL Ltd.), measure the particle diameter of each particle, and then divide 200 The particle diameter of the particles was calculated as an average value. In addition, the average pore diameter was computed using the image analysis program of said JEM-1230 (JEOL Ltd.).

manufacture example 1

[0176] Distilled water (240 g, manufactured by Wako Pure Chemical Industries, Ltd.), triethanolamine (0.42 g, manufactured by Junsei Chemical Co., Ltd.), cetyltrimethylammonium bromide (2.00 g , Tokyo Chemical Industry Co., Ltd.), and stirred at 80° C. for 30 minutes. Next, tetramethoxysilane (2.29 g, manufactured by Junsei Chemical Co., Ltd.) was added, and after stirring at 80° C. for 2 hours, ultrafiltration (cut molecular weight: 12,000 to 14000), performing ultrafiltration (cut molecular weight: 12000-14000) using water once as an acid removal step. Filtration with a filter (0.5 μm) was carried out again to obtain mesoporous silica (0.4 mass %, average primary particle diameter 30 nm (particle size distribution: 20-50 nm), average pore diameter 4 nm (diameter distribution: 2 nm) as porous inorganic fine particles. -5 nm)) of dispersion A.

manufacture example 2

[0178] Add mixed alcohol (ethanol:isopropanol:n-propanol=88:4:8 (mass ratio), 237.51g, NEO Ethanol PIP (trade name, Neoetanol) while stirring in a glass container equipped with a stirrer and a thermometer. IPM), manufactured by Daishin Chemical Co., Ltd.), tetramer (1.96 g, M Silicate51 (trade name, Msilicate 51) of tetramethoxysilane (hereinafter, referred to as "TMOS" if necessary), manufactured by Tama Chemical Co., Ltd. ), hydrochloric acid (6.94 g, special grade, manufactured by Junsei Chemical Co., Ltd.), distilled water (3.60 g, manufactured by Wako Pure Chemical Industries, Ltd.), and stirred at 25°C for 3 hours to obtain partial hydrolysis of TMOS containing inorganic oxide raw material components Solution B of the condensate (0.4% by mass).

Abstract

Provided is a functional article having a water absorption layer having wear resistance as well as a water absorption function involved in condensation prevention, humidity control, fouling prevention, fogging prevention, icing prevention, and the like; also provided are an article for transport equipment and an article for construction provided with the same. Further provided is a composition for coating making it possible to form a water-absorbent coating having a water absorption function involved in condensation prevention, humidity control, fouling prevention, fogging prevention, icing prevention, and the like, and also having wear resistance. This functional article having a substrate as well as a water absorption layer provided to at least one surface of the substrate is characterized in that the water absorption layer contains a porous inorganic particulate and also an inorganic oxide serving as a binder component. This composition for coating contains a porous inorganic particulate having a mean primary particle diameter of 5-100 nm and a mean pore diameter of 1-50 nm, a metal alkoxide and / or a partial hydrolysis condensation product thereof, and a solvent.

Description

technical field [0001] The present invention relates to functional articles, articles for transportation machinery, articles for construction and compositions for coating. Background technique [0002] Conventionally, it has been known to form a coating having functions such as dew condensation, humidity control, antifouling, antifog, and antifreeze on various substrates, thereby imparting these functions to the substrates, and using In the field of construction, transportation such as automobiles, electronic equipment, electrical equipment and other fields. [0003] For example, Patent Document 1 and Patent Document 2 describe techniques in which a composition containing porous inorganic fine particles having the above functions, specifically porous silica fine particles, etc., and a binder resin is applied to a substrate. After being placed on the material, it is dried to form a film containing it. [0004] However, in the coatings with the above-mentioned functions of a...
