Nylon and fiberglass products have bubbles
Nylon and glass fiber - at present, there are three kinds of flame retardants commonly used in flame retardant PA: halogen flame retardant, inorganic flame retardant and phosphorus nitrogen flame retardant. The halogen flame retardant has added advantages of small amount, higher flame retardant efficiency, but in the combustion process releases large amounts of toxic gas, easy to cause the fire personnel from poisoning, and because of environmental problems and the use is limited. Inorganic flame retardant has the advantages of good thermal stability, non-volatile, non-toxic and other advantages, but the added amount is large, and the mechanical properties of the materials are obviously reduced after filling. The phosphorus nitrogen halogen free flame retardant not only overcomes the shortcomings of halogenated flame retardants releasing toxic gas, but also solves the problem of low flame retardant efficiency of inorganic flame retardants, and has been used more and more widely. GF reinforced halogen free flame retardant PA6 modified material was prepared by using high fluidity PA6 as raw material. The utility model has the advantages of good fluidity, easy processing and molding, and is more suitable for the production of plastic products with complicated thin wall and complex structure.
High mobility nylon (PA) is a kind of resin material with high melt flow rate (MFR), easy processing, high strength and high toughness. It has a broad market prospect in automotive and electronic components and other fields. In recent years, remarkable progress has been made in the preparation of high fluidity PA6 by polymerization of monomer initiated by branching units. Dupont, DSM, Rhodia, BASF and other companies have realized the industrialization of high fluidity PA. Our research for the high mobility of PA nylon limited to theoretical synthesis, Zhuzhou times new materials Polytron Technologies Inc in China to realize the high mobility of PA6 research and industrial production, to further explore the high liquidity value of PA, the development of flame retardant PA material, for the further development of China's PA industry growth has great practical significance.
Long glass fiber reinforced PA6 is a lightweight and high strength thermoplastic composite. Compared with the short fiber reinforced materials, long glass fiber reinforced nylon 6 composite material has more outstanding mechanical properties, heat resistance, creep resistance and long-term performance, can be applied to more demanding occasions, especially is widely used in rail transportation, engineering machinery, automotive, military and other fields. But the long glass fiber reinforced PA6 composites with other polymer composite materials, in the storage, transportation and use of the process, such as light, heat, oxygen, moisture, grease and other environmental factors, aging, product performance decline, finally lose value, for polymer composite components and semi structural parts generally, the storage life and service life requirements, in order to ensure the reliability of material. At present, the research on long fiber reinforced nylon composites is mainly focused on the preparation technology of composite materials, the relationship between properties and structures of materials, and the evaluation of the aging properties and service life of materials
