Problems solved by technology

They either put forward many special requirements for the raw materials for the preparation of these inorganic mineral reinforced nylon 6 composites, or they sacrifice the excellent mechanical and thermal properties of certain glass fiber reinforced materials as a price, although the corresponding good performance of the parts can be obtained from them. The apparent quality, but the mechanical properties and thermal properties of the material will inevitably suffer a large loss

Abstract

The invention discloses a nylon 6 composite material for appearance quality toughening and reinforcing and a preparation method thereof. The nylon 6 composite material comprises by weight percentage 20-75 percent of nylon 6 resin, 1-10 percent of compatilizer, 10-40 percent of glass fiber, 10-40 of toughening masterbatch and 0.5-3 percent of other additives. The specific steps are that: every material is weighed except the glass fiber and mixed in a mixer for 3-5 minutes; the well-mixed material is put in a twin-screw extruder, wherein, the glass fiber is added in a first exhaust port, and the temperature from a feeding port to an extrusion die head is respectively 160-180 DGE C, 190-220 DGE C, 210-240 DGE C, 220-250 DGE C, 210-240 DGE C; the rotating speed of a host is 20-50 Hz, and thena sample is prepared by an injection moulding machine. The nylon 6 composite is characterized by no exposure of glass fiber and warping, good heat resistance and easy processing.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and in particular relates to a toughened and reinforced nylon 6 composite material with good apparent quality and a preparation method thereof. Background technique [0002] Generally speaking, nylon 6 has excellent mechanical properties, thermal properties, impact resistance and chemical resistance, so it is widely used in automobile parts, electronic and electrical parts, household goods parts and other fields. Among them, inorganic mineral-reinforced nylon 6, especially glass fiber-reinforced nylon 6, is widely used in automobiles, machinery, home appliances, Aviation and military components and other fields. However, in the actual application process, some materials need better toughness and appearance quality, and at the same time, there are more cost-effective and more convenient products in terms of price and processing. Simply adding glass fibers to nylon 6 can greatly improve...
