Embodiment Construction
[0008] Below in conjunction with specific embodiment, the present invention is described in further detail, but the present invention is not limited to following examples of implementation:
[0009] This embodiment uses co-rotating twin-screw extruders and conventional injection molding machines; PA6 is produced in Shijiazhuang Zhuangyuan, Hebei, PA66 is produced in Pingdingshan Shenma Group, Hebei, GF is produced in Zhejiang Jushi Group, BPS is produced in Dahu Chemical in the United States. Phosphorus flame retardant DOPO (oxygen, phosphaphenanthrene oxide) is produced in Sanko Company of Japan, and other processing aids are domestically produced.
[0010] The preparation process of the high-performance, green and environmentally-friendly flame-retardant reinforced PA66 composite material described in the present invention is as follows: (1) Select the reinforced dispersion-type screw combination, and the shearing should not be too concentrated, but should be dispersed, so th...

Abstract
The invention discloses a preparation technology of a high-performance environmentally-friendly flame-retardant reinforced PA66 composite material. The high-performance environmentally-friendly flame-retardant reinforced PA66 composite material is prepared from PA6, PA66, GF and a novel halogen-phosphor composite flame retardant as main raw materials, and proper amounts of a compatilizer, a flexibilizer, a dispersant, a lubricant, a heat stabilizer and a coupling agent; and the high-performance environmentally-friendly flame-retardant reinforced PA66 composite material comprises 5-20 parts of PA6, 20-50 parts of PA66, 15-30 parts of GF, 15-30 parts of the novel halogen-phosphor composite flame retardant and 0-15 parts of the compatilizer. The preparation technology comprises the following steps of weighing the above materials according to the above ratio and carrying out blending extrusion by a double screw extruder. Through use of the novel halogen-phosphor composite flame retardant, synergism is produced and a perfect gas-solid phase flame-retardant system is formed. The high-performance environmentally-friendly flame-retardant reinforced PA66 composite material has no toxicity, resists migration and has good flame retardation. The high-performance environmentally-friendly flame-retardant reinforced PA66 composite material has good surface quality, excellent mechanical properties, electrical insulation properties and flame retardation and can be widely used in fields of automobiles, electronic and electric appliances, machinery and aviation. The preparation technology has the advantages of strict control, high production efficiency and stable quality.
Description
technical field [0001] The invention discloses a high-performance, green and environment-friendly flame-retardant reinforced PA66 composite material preparation process. It specifically relates to a composite material with good surface quality, excellent mechanical properties, electrical insulation properties and flame-retardant properties, which is widely used in the fields of automobiles, electronics, machinery, aviation and the like. Background technique [0002] Although glass fiber reinforced PA66 has excellent strength, its flame retardancy cannot meet the requirements of the home appliance industry. This is because PA66 is a flammable material with an oxygen index of 24.3, and it is more flammable due to the "wick" effect of glass fiber. Can not meet the flame retardant requirements. With the development of consumer electronic products, the entire flame retardant engineering plastics industry has also developed rapidly, and the environmental protection requirements, ...
