Problems solved by technology

However, there is little improvement in improving the impact toughness of materials. In order to expand its application range, it is urgent to improve its impact properties.
[0004] Chinese patent CN1462771 uses nano-styrene-butadiene rubber to modify polyphenylene sulfide. This patent is mainly used for pure glass fiber reinforced polyphenylene sulfide, not suitable for inorganic mineral reinforced polyphenylene sulfide composite materials
Similarly, Chinese patent CN1513914 proposes the use of olefin resin and polyphenylene sulfide to form a polyphenylene sulfide composition, which is also not suitable for the manufacture of highly filled reinforced polyphenylene sulfide composites

Embodiment 1～10

[0017] Polyphenylene sulfide, inorganic mineral fillers, glass fibers, impact modifiers, coupling agents, antioxidants and processing aids are dispersed and mixed in a high-speed mixer in proportion, then melted, kneaded, and processed by a twin-screw extruder. Extrusion, cooling, drying, pelletizing and packaging. The temperature of each partition of the screw barrel of the twin-screw extruder used should be kept at 300° C., the aspect ratio of the screw element of the twin-screw extruder is 35, and the screw speed is 400 rpm.

[0018] The composite material of the present invention was prepared according to the above preparation method. The content of each component in Examples 1-4 is shown in Table 1, the content of each component in Examples 5-7 is shown in Table 2, and the content of each component in Examples 8-10 is shown in Table 3. The composites prepared in each embodiment were injection-molded into standard specimens for testing according to standard dimensions, and...

Abstract

A high-toughness filler reinforced polyphenylthioether material with flame-retarding, thermal stable and mechanical performance is proportionally prepared from polyphenylthioether, glass fibres, inorganic mineral filler, impact modifier, coupling agent, antioxidizing agent and assistant.

Description

technical field [0001] The invention relates to a high-toughness filled reinforced polyphenylene sulfide composite material and a preparation method thereof. Background technique [0002] Polyphenylene sulfide (PPS), also known as polyphenylene sulfide and polyphenylene sulfide, is a new type of special engineering plastic that was first created and put into production by Phillips Petroleum Co. of the United States in 1968. Due to the phenylthio group on the main chain of its molecule, the sulfur atom and the benzene ring are neatly arranged alternately, which endows the molecule with highly stable chemical bond characteristics, and is easy to stack into a crystal lattice structure with high thermal stability, making it have many unique properties. The performance is mainly manifested in: excellent thermal stability, chemical stability, dimensional stability, corrosion resistance and electrical properties, excellent physical and mechanical properties, good adhesive propertie...
