For example, toilet seats, bathtubs, washbasins, etc. Or, even in the case of hygiene products that are required to be hygienic because the skin is very close to each other and to have an aesthetic appearance, they are made of resin in a large proportion due to their light weight and low cost. It is replacing things.

This is because the amount of the inorganic antibacterial and antifungal material that can be added is up to about 5% by weight with respect to the resin, and if it is added in excess of this, the properties of the resin, such as strength and surface smoothness, are reduced. Is. When the addition amount is about 5% or less, the proportion of the antibacterial and antifungal material exposed on the resin surface becomes extremely small, and therefore the antibacterial and antifungal performance cannot be sufficiently exhibited.

In the antibacterial and antifungal resin product described, the calcium phosphate compound carrying at least one metal ion selected from silver, copper and zinc is contained in the resin, and a molded product made of this resin is obtained by acid washing. Was used as a means for solving the above problems. In the antibacterial and antifungal resin product according to the second aspect, the resin product is a sanitary product such as a toilet seat, a bathtub, a wash basin, etc.

The antibacterial and antifungal resin product of the present invention is a sanitary product such as a toilet seat, bathtub, washbasin, and the like, and is a calcium phosphate compound carrying at least one metal ion of silver, copper and zinc. It is contained in a resin and is obtained by acid-washing a molded product made of this resin. As the resin used as the base material of the product, those generally used such as phenol / formaldehyde resin (PF), unsaturated polyester resin (UP), and methacrylate resin (MMA) are used.

い。Further, since metal ions such as silver, copper and zinc have antibacterial and antifungal properties, they are also used as antibacterial and antifungal materials in the present invention. Since these cannot be expected, they are used by supporting them on an inorganic ion exchanger. Further, in the present invention, calcium phosphate is used as the inorganic ion exchanger, and at least one of the metal ions is added to the calcium phosphate.
Support the seeds. As the calcium phosphate, apatite, brushite, monetite, calcium pyrophosphate, tricalcium phosphate, tetralime phosphate and the like are preferably used. The method of supporting the metal ion on these calcium phosphates is preferably carried out by adding the metal ion during the synthesis of calcium phosphate.

らである。Regarding the addition of the metal ion-supported calcium phosphate thus obtained to the resin, it is added to the resin before molding, kneaded, and then molded into a desired shape under predetermined molding conditions. The amount of the metal ion-supported calcium phosphate added is generally 1 to 5 parts by weight with respect to 100 parts by weight of the resin, although it depends on the type of the resin. This is because if it is less than 1 part by weight, the antibacterial and antifungal effect due to the addition is not sufficiently obtained, and if it exceeds 5 parts by weight, the strength and surface smoothness of the obtained molded article are deteriorated.

もできる。The resin product of the present invention is obtained by molding on a toilet seat, bathtub, washbasin, etc., and then subjecting the molded body to acid cleaning. As the acid used, any acid may be used as long as it does not deteriorate the resin used in the molded body and does not completely dissolve calcium phosphate, and strong acid or weak acid can be used. is there. However, when the acid used deteriorates the resin to some extent or dissolves the calcium phosphate, it is necessary to appropriately determine the type and concentration of the acid and the washing time by conducting experiments in advance. As for the cleaning method, the dipping method is the easiest and preferred, but a showering method or a spraying method can also be employed.

オンの活性が大きくなるためと推測される。In the antibacterial and antifungal resin product according to claim 1 of the present invention, since the calcium phosphate compound carrying at least one metal ion of silver, copper and zinc is used as the antibacterial and antifungal material. The antibacterial and antifungal performance can be maintained as compared with the case of simply containing metal ions. Moreover, since the molded body is washed with an acid, the antibacterial and antifungal performance of the calcium phosphate compound carrying the metal ions is enhanced. Here, when a substance other than the calcium phosphate compound is used as the metal ion carrier, no increase in antibacterial and antifungal performance due to acid washing is observed as shown in the experimental results described later. Although it cannot be completely elucidated whether the combination of calcium phosphate and acid is effective in increasing the antibacterial and antifungal performance, the proton of the acid has a high ion exchange property with the metal carried in the calcium phosphate. Therefore, it is presumed that the activity of metal ions is increased for this reason.

Next, this solution is aged for 24 hours and then 100 ° C.
Then, the powdery granules of 6 kinds of calcium phosphate compounds supporting antibacterial and antifungal metal were obtained. For comparison, the calcium phosphate suspension was directly dried without adding metal nitrate to obtain calcium phosphate powder.

Further, a plurality of toilet seats were molded from these four kinds of kneaded products. Of the four types of molded products, some of the molded products were washed with hydrochloric acid having a concentration of 10%. For the cleaning treatment, the temperature of the hydrochloric acid solution should be 20
After immersing in the hydrochloric acid solution at 10 ° C. for 10 minutes, the acid was washed off with tap water and the surface water was wiped off.

Then, an antibacterial test and an antifungal test were carried out on these, and the results are shown in Table 1. As an antibacterial test, a halo test is performed in accordance with AATCC TEST Method 90 (1982), and as an antifungal test, JIS-Z-2911 is used.
