Problems solved by technology

In order to meet the thin-walled and high-performance enhancement of flame-retardant materials, the processing conditions are more stringent, so that it is easy to cause yellowing and blackening of the material due to a slightly higher local temperature during processing, which will lead to the deterioration of all aspects of the material. The performance drops quite severely, and it cannot meet the requirements of appearance

Abstract

The invention discloses a glass fiber reinforced environment-friendly flame retardation nylon alloy used for thinwalled articles. The glass fiber reinforced environment-friendly flame retardation nylon alloy mainly comprises the following components: 25 to 35 percent of nylon 66 resin, 8.85 to 16.55 percent of nylon 6 resin, 25 to 30 percent of glass fiber, 3 to 6 percent of glass micro-bead, 14 to 20 percent of TDE, 4 to 7 percent of antimony trioxide, 0.05 to 0.15 percent of antioxidant 1010, 0.1 to 0.3 percent of antioxidant 168, and 1 to 4 percent of compatilizer EPDM-g-MAH. The preparation method for the nylon alloy comprises the following steps: weighing the substances of the components by weight percentage; mixing the components evenly and adding the components into a twin screw extruder; then quantitatively and continuously adding the glass fibers for full fusion and compounding in the twin screw extruder; and finally packaging the product after machine head extrusion, bracing, cooling, granulation and drying. The invention aims to provide the glass fiber reinforced environment-friendly flame retardation nylon alloy with high flame retardant property and thinwalled performance.

Description

technical field [0001] The invention relates to a glass fiber reinforced environment-friendly flame-retardant nylon alloy used for thin-walled products, and also relates to a preparation method of the nylon alloy. Background technique [0002] Nylon ranks first among the five major engineering plastics (polyamide, polycarbonate, polyoxymethylene, modified polyphenylene ether, thermoplastic polyester). Nylon 66 is not only the earliest successfully developed nylon variety, but also as the main variety in nylon, together with nylon 6, it accounts for about 90% of the total nylon output. [0003] Nylon 66 has good mechanical properties, and has high strength, rigidity and toughness in a wide range. Excellent wear resistance, creep resistance and self-lubrication. It has good heat resistance and low temperature resistance, and is a self-extinguishing material. However, with the development of my country's electrical and electronic industry towards miniaturization, thinner wal...
