本発明は家庭用品、特に食器等に用すられる不飽和ポリ
エステル樹脂成形材料に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an unsaturated polyester resin molding material used for household goods, particularly tableware and the like.
従来、不飽和ポリエステル樹脂成形材料は電気電子機器
部品、電気構造部品、ハウジング部品家庭用品等に広く

た。Conventionally, unsaturated polyester resin molding materials have been widely used for electrical and electronic equipment parts, electrical structural parts, housing parts, household goods, etc., but as disclosed in Japanese Patent Application Laid-Open No. 63-12658, they are particularly useful for tableware, etc. When used in household products, the smell of styrene becomes a problem. 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.
従来の技術で述べたように、従来の不飽和ポリエステル
樹脂成形材料ではスチ、レン臭を除去することができず
、食器等の家庭用品への普及には制約があった。本発明

ので、その目的とするところは、スチレン臭のなり不飽
和ポリニスデル樹脂成形材料を提供することにある。As described in the section on the prior art, conventional unsaturated polyester resin molding materials cannot remove the smell of stucco or polymer, which limits their 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 polynisder resin molding material that has no styrene odor.
本発明は香料を０．０５〜 ｌＯ重ｆｔ％（以下毘にチ
と記す）含有したことを特徴とする不飽和ポリエステル
樹脂成形材料のため、香料によってスチレン臭を除去す
ることができたもので、以下本発明の詳細な説明する。The present invention is an unsaturated polyester resin molding material characterized by containing 0.05 to 10% by weight of fragrance (hereinafter referred to as ``chi''), so that the styrene odor can be removed by the fragrance. The present invention will be described in detail below.
本発明に用−る香料はスチレン臭除去後の芳香の種類に
より任意に選択することができるものであるが添加量は
全階の０．０５〜 ｌｏ ４であることが必要である。The fragrance used in the present invention can be arbitrarily selected depending on the type of fragrance after the styrene odor is removed, but the amount added must be 0.05 to 4.
即ちｏ、０５％未満ではスチレン臭を除去することがで
きず、１０％をこえると刺激的芳香となるからである。That is, if it is less than 0.05%, the styrene odor cannot be removed, and if it exceeds 10%, it becomes an irritating aroma.
