Problems solved by technology

However, the modification methods currently used are very targeted, and some properties cannot be taken into account
Glass fiber is cheap, its strength and Young's modulus are 10 times larger than nylon resin, its water absorption is very low, its heat resistance and chemical resistance and mechanical properties are excellent, it is an ideal engineering reinforcement material, but when the glass fiber When the content exceeds 40%, its reinforcing effect becomes inconspicuous, but the ductility decreases, and floating fibers appear on the surface, and the gloss decreases, etc.

preparation example Construction

[0028] An embodiment of the present invention also provides a method for preparing a glass fiber reinforced nylon composite material, comprising the following steps:

[0029] S110, weighing and drying the raw materials according to the above weight percentage, wherein the drying condition of the nylon resin is 4-8 hours at 80-100°C;

[0030] S120. Evenly mix the dried nylon resin, nano-layer silicate, compatibilizer, lubricant and antioxidant into the hopper of the twin-screw extruder, and feed in the side of the twin-screw extruder. Add chopped glass fiber at the feed port and extrude;

[0031] For example, add the dried nylon resin, nano-layered silicate, compatibilizer, lubricant and antioxidant into a high-speed mixer and mix for 15-20 minutes to mix the raw materials evenly before adding them to the twin-screw extruder.

[0032] Specifically, the process conditions of the twin-screw extruder are set as follows: the temperature of the first zone is 200-220°C, the temperat...

Embodiment 1

[0047] The glass fiber reinforced nylon composite material in Example 1 of the present invention comprises the following components in the following weight percentages:

[0048] Nylon 6: 65.4%, chopped glass fiber: 30%, nano-phyllosilicate: 2%, compatibilizer: 2%, lubricant: 0.3%, antioxidant: 0.3%.

[0049] The method for preparing a glass fiber reinforced nylon composite material in Example 1 of the present invention comprises the following steps:

[0050] Nylon 6 was dried at 100°C for 6 hours, and nano-mica was dried at 100°C for 8 hours. Stir the dried nylon 6, nano-mica, compatibilizer, lubricant, and antioxidant in a high-speed mixer for 3 minutes, then add it to the hopper of the twin-screw extruder, and feed it at the side feeding port of the twin-screw extruder Add chopped glass fiber. The process conditions of the twin-screw extruder are set as follows: the temperature of the first zone is 200-220°C, the temperature of the second zone is 220-240°C, the temperature...

Abstract

The invention provides a glass fiber reinforced nylon composite material. The composite material is prepared from the following components in percentage by weight: 35-66.8 percent of nylon resin, 30-60 percent of chopped glass fibers, 2-15 percent of nano-phyllosilicate, 1-5 percent of compatilizer, 0.1-1 percent of a lubricating agent and 0.1-1 percent of antioxidant. According to the glass fiber reinforced nylon composite material, the nano-phyllosilicate filler and glass fibers are used for synergically reinforcing, advantages of a glass fiber reinforced nylon composite material are maintained, the strength and toughness of the composite material are further improved, the defects of poor size stability, poor surface and the like of the material caused by reinforcing adopting high glass fiber content can be overcome, and the color of the material is little influenced. Furthermore, the glass fiber reinforced nylon composite material has excellent mechanical performance and good fluidity, and can be applied to manufacture of machinery and automobile parts requiring high strength.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a glass fiber reinforced nylon composite material. Background technique [0002] Nylon (Nylon), scientific name Polyamide (Polyamide), referred to as PA, refers to the general term for thermoplastic resins with amide groups (—NHCO—) repeating structural units on the polymer chain. Although there are many types of polyamides, they are mainly prepared by two methods, one is prepared by the polycondensation reaction between the functional groups of dicarboxylic acids and diamines; the other is prepared by ring-opening with caprolactam or ω-aminocaproic acid aggregated. With the development of society, engineering plastics have been widely used in automobile manufacturing, electronics, aerospace and other industries, but the use environment of engineering plastics will become more and more harsh, such as high temperature, high voltage, high humidity, high load, chemical R...
