られな論ものであった。Conventionally, many unsaturated polyester resin molded articles contain styrene monomer as a composition, and while the styrene monomer is polymerized and crosslinked during the curing process, the S-styrene monomer remains within the molded article. This styrene monomer has a strong odor, even if it is only slightly present, and gives a feeling of discomfort. For this reason, attempts have been made to heat-treat unsaturated polyester resin molded products in a hot air oven after molding, but this requires long-term heating, and even then, residual styrene monomer remains and the odor is large and the long-term heating Discoloration of molded products was inevitable.

The present invention has been made in view of the above-mentioned problems in the prior art, and its object is to provide an unsaturated polyester resin molded article that has almost no styrene monomer odor.

ない樹脂成形品を得るものである。The unsaturated polyester resin used in the present invention is not particularly limited, and any unsaturated polyester resin can be used. As the crosslinking agent, one that is liquid at room temperature or solid at room temperature, such as styrene monomer, can be used.Although this is not limited to this, it is preferable to use diallylphate monomer to improve heat resistance. It is also possible to add triallyl iso V annulate in combination with a crosslinking agent to increase the crosslinking density to further improve heat resistance. Fillers include inorganic fillers such as clay silica, calcium carbonate, talc, and aluminum hydroxide, and aIMs such as glass fiber, asbestos, valve, and wood powder.
Fillers and the like can be used. The thermoplastic resin as a low shrinkage agent, a crosslinking agent, a 1-coin initiator, a mold release agent, a spring coloring agent, etc. are not particularly limited and may be added as necessary. The thus obtained unsaturated polyester resin molding material is subjected to compression molding, extrusion molding, transfer molding, injection molding, and lamination molding to obtain a resin molded product. Next, the aIf#t resin molded product is heated with far infrared rays to reduce the residual styrene monomer residual*t-in to 4 or less to obtain an odorless resin molded product.
