C1 Widely used in electronic equipment parts, electrical structural parts, housing parts, household goods, etc.
As disclosed in , styrene odor has been a problem especially when used in household items such as tableware. As a countermeasure to this problem, the use of specific unsaturated polyester resins and polymerization initiators was considered, but the styrene odor could not be removed.

The I' resin molding material cannot remove the styrene odor, which limits its widespread use in household items such as tableware. 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 molding material free of styrene odor.

。The present invention contains a filler with a built-in fragrance of 5 to 50% by weight (hereinafter simply %).
unsaturated polyester characterized by containing
Since it is a V-resin molding material, the styrene odor can be removed by using a fragrance, and the present invention will be described in detail below.

質の充填剤が好゛ましい。The fragrance used in the present invention can be arbitrarily selected depending on the H group of the aroma after the styrene odor is removed, and the amount added is 5 to 50% as a filler when incorporated in the filler. As the filler, hollow or porous fillers such as vermiculite and pearlite are preferred.

If it exceeds 50%, the strength will be insufficient.The composition of the unsaturated polyester resin molding material other than the filler with built-in fragrance is the conventionally used unsaturated polyester fat,
Crosslinking agents, polymerization initiators, reinforcing materials, fillers, colorants, M type agents, surfactants, etc. can be used as they are, and unsaturated can be achieved by blending, mixing, kneading, and crushing and granulating as necessary. A polyester resin molding material is obtained.
