Definitions

  • the present invention relates to a polyacetal resin composition. More specifically, a polyacetal composed mainly of a polyacetal resin and blended with a thermoplastic polystyrene resin and a thermoplastic acryl resin, has a good surface condition of the molded product, has low friction and wear, and has low molding shrinkage.
  • the present invention relates to a resin composition.
  • the polystyrene resin of the component B used in the present invention is a resin obtained by a radical polymerization reaction or an ionic polymerization reaction mainly containing styrene, and is industrially a bulk polymerization, a solution polymerization, and a polymerization. Any of those obtained by suspension polymerization, emulsion polymerization and the like can be used.
  • the polystyrene resin B of the present invention is mainly composed of styrene in addition to polystyrene as long as its properties are not significantly impaired, and has the ability to copolymerize reactive monomers such as other butyl compounds and gen compounds. , A rubber component may be introduced.
  • Friction and wear test The specific wear on steel S55C was measured using a Suzuki-type friction and wear tester.

Abstract

Résine polyacétal non touchée par la délamification ni par d'autres problèmes de moulage et de traitement dus à la résine de polystyrène ajoutée pour améliorer diverses caractéristiques de la résine polyacétal. Ladite résine polyacétal permet d'obtenir un article moulé présentant un excellent état de surface, un frottement et une abrasion réduits, et un retrait de moulage diminué. La composition comporte de 55 à 95 parties en poids d'une résine polyacétal, de 43 à 3 parties en poids d'une résine de polystyrène thermoplastique, et de 20 à 2 parties en poids d'une résine acrylique thermoplastique, à titre de troisième composant, représentant une quantité globale de 100 parties en poids, la combinaison de résine polyacétal et de résine de polystyrène étant sélectionnée de manière à obtenir une valeur prédéterminée de fluidité en fusion.
