Problems solved by technology

[0008] Although the existing technology can solve the effective compounding of virgin nylon and glass fiber, for the re-melting processing of glass fiber reinforced nylon, there is still no effective means to avoid the damage of glass fiber in the conveying section and the first shear melting plasticizing section

Embodiment 1

[0044] In this embodiment, the method of preparing recycled glass fiber reinforced nylon 66 composite material by using self-designed pulse extrusion screw is as follows:

[0045] (1) Weigh 100 parts of dried glass fiber reinforced nylon 66 crushed material, 1 part of dried recycled polyethylene / nylon 6 composite particles, 1 part of PETS external lubricant, 1 part of CYD-816A internal lubricant, anti-oxidant Add 0.4 parts of agent 1098 and antioxidant Irgafos168 (mass ratio is 1:1), put them into a high-speed mixing mixer and stir to mix evenly;

[0046] (2) Feed the mixed material obtained in step (1) into the twin-screw extruder through the feeding port, the screw speed is 250rpm, and the temperature of each zone is set to 250°C for the first zone of temperature control, 270°C for the second zone of temperature control, and 270°C for the second zone of temperature control. Three zones 280°C, temperature control four zones 260°C, temperature control five zones 270°C, tempera...

Embodiment 2

[0048] The only difference between Example 2 and Example 1 is that the added amount of regenerated polyethylene / nylon 6 composite particles after drying is 5 parts.

Embodiment 3

[0050] The only difference between Example 3 and Example 1 is that the added amount of regenerated polyethylene / nylon 6 composite particles after drying is 10 parts.

Abstract

The invention belongs to the technical field of polymer composite materials, and particularly relates to a regenerated glass fiber reinforced nylon 66 composite material and a preparation method thereof. A self-designed pulse extrusion screw is adopted, regenerated polyethylene/nylon 6 composite particles, an external lubricant, an internal lubricant and an antioxidant are added for regeneration modification aiming at glass fiber reinforced nylon 66 crushed materials from recycled automobile water tanks, and the glass fiber reinforced nylon 66 composite material is prepared. The mechanical property retention rate can reach more than 90% of that of a crushed material, and the mechanical strength is far higher than that of a regenerated material prepared by a conventional method. And the recycled glass fiber reinforced nylon and polyethylene/nylon 6 composite particles are adopted, so that the recycling value of the waste plastic is improved, and the industrial application prospect is very good.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a regenerated glass fiber reinforced nylon 66 composite material and a preparation method thereof. Background technique [0002] Polyhexamethylene adipamide, commonly known as nylon 66 (PA66), is a thermoplastic resin, which is generally made of polycondensation of adipic acid and hexamethylenediamine. It has good comprehensive properties, high strength, good rigidity, impact resistance, oil resistance, The advantages of chemical resistance, wear resistance and self-lubrication, especially hardness, rigidity, heat resistance and creep performance are better, and the raw materials are easy to obtain and low cost, so they are widely used in industries, clothing, decoration, engineering plastics and other fields . At present, the application of PA66 in vehicles has accounted for 63%, the application in electronic and electrical and office automation ...
