Example Embodiment

[0042] Example 1

[0043] Take 5640 grams of polyarylene ether nitrile, 180 grams of phthalonitrile prepolymer, 120 grams of graphite and 60 grams of silicon carbide whiskers, blend them uniformly and add them to the single-screw extruder to control the extrusion of the single-screw extruder. The outlet temperature is 330-350℃, and they are plasticized in the screw to obtain molten materials. The molten material is extruded into the die through the filter plate through the head of the extruder, and then directly enters the cooling sizing sleeve. The length of the sizing sleeve is 120mm and the diameter is D42mm. Under the combined action of the back pressure rod of the traction device and the extruder, the polyarylene ether nitrile melt moves forward at a constant speed, and is cooled and shaped by the sizing sleeve to obtain a diameter of D41mm? mm polyarylene ether nitrile rod.

[0044] After cutting the polyarylene ether nitrile bar, it is put into a box annealing furnace for...

Example Embodiment

[0051] Example 2

[0052] As in Example 1, just change the formula to 3780 grams of polyarylene ether nitrile, 300 grams of phthalonitrile prepolymer, 120 grams of graphite and 1800 grams of glass fiber, and then add them to the single screw extruder. According to the method and process, the polyaryl ether nitrile rod is obtained.

[0053] The roundness of the bar prepared in this example was studied. Therefore, the diameter of the bar was measured at 5 different points on the cross section of the prepared bar. The results are as follows:

[0054] Table 3 Diameter data of polyarylene ether nitrile rod prepared in Example 1

[0055]

[0056] Table 4 Performance data of polyarylene ether nitrile rods prepared in Example 1

[0057]

[0058] It can be seen from Tables 3 and 4 that the prepared polyarylene ether nitrile rods have uniform cross-sections and high mechanical strength and heat resistance.

[0059] Example 3

[0060] As in Example 1, just change the formula to 4380 grams of polyarylene ether nitrile, 300 grams of phthalonitrile prepolymer, 120 grams of polytetrafluoroethylene and 1200 grams of carbon fiber, and then add them to the single screw extruder. , The same method and process, to obtain polyaryl ether nitrile rod.

[0061] The roundness of the bar prepared in this example was studied. Therefore, the diameter of the bar was measured at 5 different points on the cross section of the prepared bar. The results are as follows:

[0063]

[0064] Table 6 Performance data of polyarylene ether nitrile rods

[0065]

[0066] It can be seen from Tables 5 and 6 that the prepared polyarylene ether nitrile rods have uniform cross-sections and high mechanical strength and heat resistance.

Abstract

The invention belongs to the fields of a plastic products and sectional materials thereof, in particular to a poly-arylene ether nitrile composite material, a poly-arylene ether nitrile bar and a preparation method thereof. The technical problem to be solved in the invention is to provide the poly-arylene ether nitrile composite material suitable for extrusion molding. The poly-arylene ether nitrile composite material contains the following components in parts by weight: 63 to 100 parts of poly-arylene ether nitrile, 3 to 5 parts of plasticizers, 2 to 4 parts of lubricants and 0.05 to 30 parts of fillers. The poly-arylene ether nitrile composite material can be used for preparing the poly-arylene ether nitrile bars or plates by extrusion molding, and then the poly-arylene ether nitrile bars or plates can be used for preparing various parts in the fields of aerospace, automobiles, machinery, chemical industry and the like.

Description

technical field [0001] The invention belongs to the field of plastic products and profiles thereof, and in particular relates to a polyarylether nitrile composite material, a polyarylether nitrile rod and a preparation method thereof. Background technique [0002] Polyarylene ether nitriles (PEN) is a kind of semi-crystalline polymer with nitrile groups on the side chain, which was first developed for the needs of national defense and cutting-edge technology since the 1980s. It is a kind of structural polymer material with excellent comprehensive performance, which has excellent characteristics such as high heat resistance, flame retardancy, mechanical strength, UV protection and creep resistance. Since its commercialization, it has been widely used in aerospace, automobile, electrical and electronic, chemical industry, machinery and other fields. Polyarylether nitrile products used in the above fields are generally manufactured by injection molding, but some products have ...
