Abstract

The invention discloses a halogen-free flame-retardant reinforced semi-aromatic polyamide molding composition and molding products with a specific glass fiber length. The molding composition consists of the following components: (A) 25 to 90 parts of at least one semi-aromatic polyamide resin; (B) 5 to 60 parts of glass fibers having an arithmetic mean length of 200 μm to 420 μm; (C) 5 parts to 25 parts of at least one phosphinate and / or at least one diphosphinate; (D) 0 parts to 40 parts of additives. The halogen-free flame retardant reinforced semi-aromatic polyamide molding compositions of the present invention having a specific glass fiber length have improved properties compared to molding compositions having glass fibers having an arithmetic mean length of 200 μm to other than 500 μm. Therefore, the moldings made from the molding compositions of the present invention can be used for specific applications in the electrical and electronic industries, especially in areas with precision component requirements.

Description

technical field [0001] The present invention belongs to the field of polymer blend modification, in particular to a flame retardant polyamide molding composition, and also to moldings of the composition. Background technique [0002] Polyamide is widely used because of its good comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubrication, low friction coefficient, certain flame retardancy, and easy processing. It is suitable for filling reinforcement and modification with glass fiber and other fillers to improve performance and expand the scope of application. In recent years, semi-aromatic polyamides have been mainly developed due to their better heat resistance and mechanical properties. [0003] Plastics are subject to stringent requirements regarding their flame retardancy in some applications. Providing flame retardancy to plastics is particularly necessary for use in electronic equipment due to ...
