〔産業上の利用分野〕
本発明は住宅機器用、建築部材用、衛生機器用、電気機
器用等、特に光沢、透明性が要求される成形品に用いら
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] [Industrial Application Field] The present invention is directed to unsaturated resins used in molded products that particularly require gloss and transparency, such as housing equipment, building materials, sanitary equipment, electrical equipment, etc. This invention relates to polyester resin molding materials.
従来、不飽和ポリエステル樹脂成形品は高強度、耐久性
に優れ、成形時に成形材料の流動性がよい為、低圧成形
で大型成形品を成形することができるが、通常用いられ
ている脂肪酸金属塩からなる離型剤では金属塩が成形品
表面にブリードアウトして光沢、透明性が低下する欠点
があった。Conventionally, unsaturated polyester resin molded products have high strength and durability, and the fluidity of the molding material during molding is good, so large molded products can be formed by low-pressure molding.However, the commonly used fatty acid metal salts A mold release agent consisting of the above had the disadvantage that the metal salt bleed out onto the surface of the molded product, resulting in a decrease in gloss and transparency.
（発明が解決しようとする問題点〕
従来の技術で述べたように、従来の不飽村ポリエステル
樹脂成形品は光沢、透明性が低下する問題点があった。(Problems to be Solved by the Invention) As described in the prior art section, conventional Fufumura polyester resin molded products have the problem of reduced gloss and transparency.
本発明は従来の技術における上述の問題点に鑑みてなさ
れたもので、その目的とするところは、光沢、透明性に
優れた成形品が得られる不飽和ポリエステル樹脂成形材
料を提供することにある。The present invention was made in view of the above-mentioned problems in the conventional technology, and its purpose is to provide an unsaturated polyester resin molding material from which molded products with excellent gloss and transparency can be obtained. .

説明する。The present invention is an unsaturated polyester resin molding material characterized by containing alkylphenyl phosphite,
The mold release agent does not bleed out onto the surface of the molded product.
The present invention will be described in detail below as it does not impede gloss or transparency.

ことができるものである。The alkylphenyl phosphite used in the present invention includes all alkylphenyl phosphites, and the amount added is preferably 0.1 to 5 minutes per 100 parts by weight (hereinafter simply referred to as parts) of the unsaturated polyester resin. . That is 0
．． This is because if the amount is less than 1 part, the mold releasability tends to decrease, and if it exceeds 5 parts, the gloss tends to decrease. Any unsaturated polyester resin can be used, and a styrene monomer or the like as a crosslinking agent can also be included. Fillers include bulbs, wood powder, glass powder, calcium carbonate,
Clay, silica, talc, aluminum hydroxide, etc. can be added. The thermoplastic resin as a low-shrinkage agent, reinforcing agents such as glass fibers and glass fiber chips, crosslinking agents, polymerization initiators, coloring agents, etc. are not particularly limited, and commonly used ones can be used as they are. The unsaturated polyester resin molding material thus obtained can be molded under heat and pressure by compression molding, extrusion molding, transfer molding, injection molding, etc. to obtain molded products with excellent gloss and transparency.
以下本発明を実施例にもとづいて説明する。The present invention will be explained below based on examples.
