た。Problems that the invention aims to solve: However, this type of bonding work for non-slip is extremely troublesome, especially when the area to which the non-slip is attached is large, and it is difficult to attach the non-slip to a synthetic resin and a rubber sheet or felt material. Since dissimilar materials are bonded together using adhesives, it is difficult to reliably maintain the bonding integrity between the two over a long period of time.For this reason, the adhesive strength of conventional products deteriorates over long periods of use. As a result, the anti-slip material peels off from the molded product, impairing its anti-slip function and deteriorating its appearance. if,
Even if the bond between the molded product body and the non-slip material is maintained for a long period of time, the non-slip material itself may be damaged, such as cracks and peeling in the case of rubber sheets, and hardening of the non-slip material in the case of felt. There were drawbacks such as the disappearance or decline of

ある。 1 is the molded product body, which is made of unsaturated polyester resin reinforced with glass fibers, that is, FRP. 2 is an anti-slip sheet, with a transparent soft thermoplastic polyurethane film 4 having a large coefficient of friction on one side of a base fabric 3 made of polyester synthetic fibers.
are laminated and integrated under heat and pressure.
As shown in the figures, it is integrally provided on the upper surface of the main body 1 with the base fabric 3 facing the molded product main body 1. The anti-slip sheet 2 and the molded product main body 1 are integrated at the same time when the main body 1 is hot-press molded. That is, as shown in FIG. 4, the molding material C is put into the female mold A of the mold, and the female mold A
A non-slip sheet 2 is placed between the base fabric 3 and the male mold B.
The side surface is placed to face the molding material C side, molds A and B are closed, heated and pressurized, and molded after an appropriate curing time. Therefore, the anti-slip sheet 2 has its base fabric 3 impregnated with a portion of the melted molding resin of the molded product body 1, and is firmly bonded to the surface of the molded product body 1 in a hardened state. It has become integrated. The above molding conditions are general molding conditions for unsaturated polyester resins. Incidentally, the molding temperature is around 170℃.

な一体化状態が得られるのである。 The fluid, liquid unsaturated polyester resin penetrates into the structure of the base fabric 3 by being pressurized, and becomes embedded in the base fabric 3 by being heated. Since it hardens over time, the anti-slip sheet 2 and the molded product main body 1 are firmly integrated as described above. In particular, in this example, since the base fabric 3 is made of polyester synthetic fiber that has good compatibility with unsaturated polyester, the base fabric 3 and the molded product main body 1 can be more strongly integrated. It will be done.

ある。 In the case of this example, the anti-slip sheet is integrally provided on the top surface of the tray as the molded product body 1, so even if the tray is tilted slightly, the tableware on the tray will not slide off and can be safely placed. can be carried. In addition, the anti-slip sheet is integrated into the tray body by impregnating and curing the tray molding resin without using adhesives, so even if it is sterilized with hot water or steam, it will not work as if it were bonded with adhesive. There is no risk that the anti-slip sheet will peel off, making it particularly suitable for use in hospitals and the like.

る。Effects of the invention As mentioned above, this invention specifically selects and uses the soft thermoplastic polyurethane film 4, which has a large coefficient of friction, as the anti-slip material. , the function is less likely to deteriorate over time and has excellent durability. Further, the anti-slip sheet 2 is constructed by laminating the thermoplastic polyurethane film 4 on the surface of a base fabric 3 made of thermoplastic synthetic fiber or natural fiber having a melting point higher than the molding temperature of the molded product body 1. Therefore, the anti-slip sheet 2 and the molded product main body 1 can be firmly bonded and integrated without using an adhesive. That is, in this invention, during hot-press molding of the molded product body 1, the anti-slip sheet 2 is integrally hot-pressed with its base fabric 3 facing the molded product body 1 side, so that the base fabric In the embodiment in which a part of the resin of the molded product main body 1 is impregnated into the cloth 3 and hardened, it is bonded and integrated with a part of the surface of the molded product main body, so that the anti-slip sheet for the molded product main body 1 is formed. 2
An extremely strong bonded and integrated state can be obtained. Therefore, the synthetic resin molded product according to this invention has no risk of the anti-slip sheet 2 peeling off from the molded product body 1, and the polyurethane film 4 has excellent durability, so it can be used for a long time. In addition to being able to withstand high temperatures, production efficiency can also be extremely good.
