Technical Field The present invention relates to porous articles, such as cast articles, metal sintered bodies, ceramics, wood, die castings, aluminum alloys, rare earth element products, etc., which have many fine pores on their surfaces and insides, or their intermediates. The present invention relates to a method for sealing and sealing the pores of a porous article by impregnating a portion with an acrylic ester monomer and then polymerizing and curing it. Prior art A method of impregnating the pores of cast products, wood, metal alloys, concrete, etc. with an impregnating agent, and then polymerizing and hardening the impregnating agent to seal the pores and improve the strength and pressure resistance of the product as well as the surface condition. is already well known. Unsaturated polyester, unsaturated epoxy resin, etc. have long been used as impregnating agents, but these have the disadvantage of having high viscosity, making it difficult to fully impregnate the inside of minute pores. Acid ester type was developed as an improved type. For example, British Patent No. 1297103 discloses an anaerobic polyfunctional acrylic ester system, and Japanese Patent Publication No. 50-20989 discloses a method using vinyl monomers such as methacrylic esters. Furthermore, JP-A-55-46644, JP-A-49-53618, JP-A-51-23417, JP-A-52-154859, JP-A-58
Various improved types have been proposed, such as in No. 32612. Although the impregnating agents disclosed in these patent applications each have their own characteristics, a common drawback is insufficient adhesion between the porous article and the cured resin. Purpose of the Invention The purpose of the present invention is to seal the micropores of a porous article by using an impregnating agent with a specific composition, and to obtain a product having even better mechanical strength than conventional products. Structure of the Invention The present invention is a method for sealing a porous article, which comprises impregnating the pores of a porous article with a mixture of an ester of acrylic acid or methacrylic acid and an unsaturated carboxylic acid, and then polymerizing and curing the mixture. The esters used in the present invention include methyl, ethyl, butyl, 2, of acrylic acid or methacrylic acid.
- Monofunctional esters such as hydroxypropyl, 2-ethylhexyl, lauryl, and stearyl; polyfunctional esters with ethylene glycol, diethylene glycol, triethylene glycol, trimethylolpropane, etc. are used, but especially monofunctional esters and polyfunctional esters A mixture with is preferred. As the unsaturated carboxylic acid, monobasic acids such as acrylic acid and methacrylic acid, or dibasic acids such as itaconic acid and phthalic acid are used, and methacrylic acid is particularly preferred. The proportion of the unsaturated carboxylic acid in the impregnating agent is preferably 1 to 10% by weight, particularly preferably 4 to 8% by weight. When adjusting the impregnating agent, it is preferable to take care not to significantly increase its viscosity. This is because it is preferable to fully impregnate the inside of the fine pores of the product. For example, when using a higher ester with a high viscosity, lower esters such as methyl methacrylate should be mixed appropriately to adjust the viscosity to the desired value. Bye. The impregnating agent used in the present invention includes a polymerization catalyst. As the polymerization catalyst, one that accelerates the polymerization and curing of acrylic ester monomers and unsaturated carboxylic acids is used, and known catalysts such as peroxide type, redox type, azobis type, etc. are used. In addition, it is preferable that the impregnating agent of the present invention contains a small amount of a polymerization inhibitor in order to increase the storage stability up to the time of impregnation, but even if heated after adding the polymerization catalyst, sufficient polymerization curing may not proceed. It should not be in large quantities. Furthermore, the impregnating agent of the present invention contains a surfactant, a diluent,
Although optional components such as a viscosity modifier and a coloring agent can be included, the amount of these added is preferably within a range that does not significantly affect the polymerization behavior of the impregnating agent. Porous articles used in the present invention include cast products of aluminum alloys, iron alloys, magnet alloys, etc., cast products of rare earth elements, molded products, wood or wood materials, concrete, metal sintered bodies, ceramics, and various other products. can be mentioned. As the impregnation method, both a vacuum impregnation method and a pressure impregnation method can be used, but a combination of the two is particularly preferred. Specifically, the cleaned porous article is placed in an impregnation tank.
After processing for about 20 minutes under a vacuum of about 12 mmHg or less,
If the impregnating agent is placed in the tank, the pressure inside the tank is increased to 6 to 7 kg/cm 2 , and the impregnating agent is left for about 30 minutes, it can be easily impregnated into the inside of the micropores. The porous article filled with the impregnating agent is polymerized and cured after being washed.
Heating in water at 80-140°C under normal pressure or pressure.
Heating may be carried out in a hot air oven at 120-130°C. The impregnated porous article is usually washed with water, but it may also be washed with water containing a surfactant.
In this case, propoxylated or ethoxylated alcohol-type nonionic surfactants are preferred;
The amount added is preferably at a concentration of 3 to 10%. Effects of the Invention The impregnating agent of the present invention has very good adhesion to articles, especially metal articles, after polymerization and curing by adding an unsaturated carboxylic acid, and the obtained pore-sealing article has excellent solvent resistance,
It not only has excellent chemical resistance, but also significantly improves mechanical strength such as pressure resistance. Next, the present invention will be explained with reference to Examples. Example 1 A cylindrical ring made of a rare earth element was placed in a glass chamber, the chamber was sealed, the pressure was reduced to 2 mmHg using a vacuum pump, and the air inside the ring was vented for 15 minutes.
Inject an impregnating agent with the composition shown below. After returning the pressure to atmospheric pressure, the ring is taken out, drained of liquid, washed with water, and then transferred to warm water maintained at 85 to 90°C for 30 minutes to polymerize and harden. Impregnating agent composition 2-hydroxyethyl methacrylate 60 parts by weight Triethylene glycol dimethacrylate 25 Methacrylic acid 5 A2BN 1 part by weight Surfactant 8 The link after curing treatment was sufficiently sealed and sealed in the pressure test. Adhesion between the cured resin and the ring was also good. Cylindrical rings impregnated and cured using the same method except that methacrylic acid was not added had low adhesion strength to the cured resin, less than 1/4 of that when methacrylic acid was used. Example 2 A sintered metal cylindrical ring was treated in the same manner as in Example 1. The resulting product was confirmed to have sufficient sealing and pore sealing through a pressure test, and the adhesion strength was approximately three times that of the same product treated using an impregnating agent that did not contain methacrylic acid. . Example 3 A sintered metal cylindrical ring and a cobalt silica cylindrical ring were hardened using an impregnating agent having the composition shown below. For impregnation, place the cylindrical ring and impregnating agent in a small beaker, reduce the pressure to 2 mmHg in a glass chamber for 10 minutes, then immerse the small beaker in warm water at 75°C and raise the temperature to 90°C.
The polymerization was cured for 20 minutes. Three measurements were carried out by varying the amount of impregnating agent used and the thickness of impregnation into the ring, and the average tensile strength values are shown in Table 1.

Example 4 A wood specimen with a dry weight of 15 g was fixed in a beaker, and after injecting an impregnating agent having the following composition, the pressure was reduced to 2 mmHg in a glass chamber for 10 minutes to impregnate it. The sample was taken out, drained, washed with water, and then polymerized and cured in warm water maintained at 85 to 90°C for 10 minutes. Impregnation agent composition 2-hydroxypropyl methacrylate 54 parts by weight Triethylene glycol dimethacrylate 25 Lauryl methacrylate 10 Methacrylic acid 8 Stearyl methacrylate 3 Surfactant 3 A2BN 0.5 The weight of the article air-dried for 72 hours after curing is 19.5
g, and the impregnation rate was about 30%. The tensile strength of this article was 12Kg. On the other hand, the tensile strength of wood specimens treated in the same manner except that methacrylic acid was not used was 5.5 kg, and the adhesiveness was less than half that.
