Syndiotactic polystyrene/polyamide/clay nano composite material

Abstract

The present invention relates to a syndiotactic polystyrene / polyamide / clay nano composite material, and is mainly aimed at resolving the problems of large brittleness, low impact strength and poor comprehensive performance in the previous composite materials. Said invention utilizes adoption of its technical scheme of that its adopts the intercalation combination-comixing combination method to prepare solfonated syndiotactic polystrene / clay nano composite firstly, then the syndiotactic polystyrene, polyamide and solfonated syndiotactic polystyrene / clay nano composite are melt-mixed and combined so as to better resolve said problems. Said nano plastic alloy has high impact strength, high strength and high heat-resisting property, and said invention can be used in industrial production of said nano composite material.

Description

technical field

[0001] The invention relates to a syndiotactic polystyrene / polyamide / clay nanocomposite material. Background technique

[0002] Syndiotactic polystyrene is a new type of engineering plastic. It is different from general-purpose polystyrene and has the following advantages: (1) high melting point, 270°C; (2) high crystallinity, and the crystallization temperature can be controlled within a wide range The range is suitable for conventional plastic processing and molding methods; (3) Excellent heat resistance and chemical resistance. Therefore, it has an excellent development prospect and a very broad potential market. The disadvantage of syndiotactic polystyrene is its high brittleness, which limits its application range. It must be modified to suit structural material applications. The characteristic properties of the improved syndiotactic polystyrene are low density, good toughness and good electrical properties, which can c...
