The present invention relates to a container made of fiber-reinforced plastic.
More specifically, the present invention relates to a fiber-reinforced plastic container that has improved chemical resistance without impairing processability, mechanical strength, etc. Conventionally, as a means to improve the chemical resistance of fiber-reinforced plastic containers, the resin composition of the molded container itself has been made to have a highly chemical-resistant composition. However, in general, when trying to improve the chemical resistance of fiber-reinforced plastics, the good processability and high mechanical strength of the fiber-reinforced plastics are reduced or lost. As a result, when attempting to improve or improve the chemical resistance of the fiber-reinforced plastic, problems such as a decrease in mechanical strength and processability, and a decrease in productivity occur. It was hot. The present invention was developed as a result of studies to solve the above-mentioned problems. Therefore, the purpose of the present invention is to significantly improve chemical resistance by modifying the surface layer of fiber-reinforced plastic containers without compromising the processability and mechanical strength required of the container itself. An object of the present invention is to provide an excellent fiber-reinforced plastic container capable of In other words, the present invention has a chemical-resistant coating cured with an aromatic primary amine curing agent on the surface of a container body made of fiber-reinforced plastic (hereinafter simply referred to as fiber-reinforced plastic), which has excellent processability and mechanical strength. The gist of the present invention is to provide a fiber-reinforced plastic container characterized by forming a transparent epoxy resin layer. As the aromatic primary amine curing agent,
Examples include 4,4'-diaminodiphenylmethane, 4,4'-diaminodiphenyl sulfone, 4,4'-diaminodiphenyl ether, and m-phenylenediamine. Hereinafter, the present invention will be described in detail by way of examples with reference to the drawings. The figure is an explanatory cross-sectional view showing an example of a fiber-reinforced plastic container according to an embodiment of the present invention. In the figure, E indicates a container made of fiber-reinforced plastic according to an embodiment of the present invention.
It is constructed by integrally forming an epoxy-based chemical-resistant resin layer 2 cured with a grade amine-based curing agent. To explain this more specifically, in this embodiment, the container body 1 is molded from a bisphenol A-picchlorohydrin type epoxy resin (Sumi Epoxy ELA128: epoxy equivalent: 190) reinforced with glass fibers, and is made of a chemical-resistant resin. Layer 2 is an aromatic amine-epichlorohydrin type epoxy resin (Sumiepoxy) mixed with 4,4'-diaminodiphenylmethane as a hardening agent.
ELM434: Consists of epoxy equivalent (110-130). Next, to briefly explain the manufacturing process of the above-mentioned fiber-reinforced plastic container E, first, a container body 1 of a desired shape is molded using a prepreg made of glass fiber impregnated with a bisphenol A-epichlorohydrin type epoxy resin. An epichlorohydrin type epoxy resin mixed with tetrafunctional diaminodiphenylmethane is applied to the surface (inner surface in this example) of the container body 1 to form a chemical-resistant resin layer 2, and then this is heated. harden. Alternatively, after curing the container body 1 formed as described above, the chemical-resistant resin layer 2 may be formed by applying and curing an epoxy resin mixed with the curing agent. Furthermore, in forming the chemical-resistant resin layer 2, it is of course possible to use a prepreg in which glass fiber or the like is impregnated with an epoxy resin mixed with the above-mentioned curing agent. The fiber-reinforced plastic container of this example described above not only has excellent mechanical strength, heat resistance and chemical resistance (particularly acetone resistance), but also has good processability. As mentioned above, the present invention has an aromatic primary compound on the surface of the container body made of fiber-reinforced plastic.
Since we have formed an epoxy-based chemical-resistant resin layer that is cured with a grade amine-based curing agent, the container body can be molded from a material with a blend that focuses on required properties other than chemical resistance, such as workability and mechanical strength. can do. Therefore, in the present invention, the container body and the chemical-resistant resin layer can be formed using materials that match the required performance of the final product. A fiber-reinforced plastic container with greatly improved drug properties can be obtained. Examples and Comparative Examples Epoxy resin “Sumi Epoxy” manufactured by Sumitomo Chemical Co., Ltd. with a viscosity (40°C) of 6000 cps was applied to a glass fiber sheet obtained by the filament winding method.
After impregnating ELA-128 (bisphenol A-epichlorohydrin type epoxy resin), it was heated and cured to obtain fiber reinforced plastic A. On the other hand, the above glass fiber sheet also has a viscosity.
After impregnating with 40,000 cps of epoxy resin "Sumi Epoxy" ELM-434 (aromatic amine-epichlorohydrin type epoxy resin) manufactured by Sumitomo Chemical Co., Ltd., it was heated and cured to obtain fiber-reinforced plastic B. The tensile strength (Kg/mm 2 ) of these two types of fiber-reinforced plastics A and B in the direction of fiber arrangement and in the direction perpendicular thereto was measured, and the results shown in Table 1 were obtained.

[Table] Also, regarding the above fiber reinforced plastic B,
When filament winding molding (molding in a resin-impregnated state) was performed, the impregnated resin was hard and brittle, making it extremely difficult to mold, and the molding speed could not be significantly slowed down to satisfy practical productivity. It was not possible to perform molding at the desired molding speed. On the other hand, as for the fiber-reinforced plastic A mentioned above, since it could be easily filament-winding molded, it was molded into the shape of a container, and the inner surface was made of shrimp chlorin hydrin containing diaminodiphenylmethane as an aromatic primary amine curing agent. A mold epoxy resin was applied, heated and cured. Ascent was placed in the resulting container, left for about 24 hours, and the inner surface of the container was examined for dissolution, swelling, etc. due to acetone, and as a result, there was no change from before adding acetone.
