Problems solved by technology

However, it has defects such as high water absorption, poor dimensional stability, insufficient toughness at low temperature and dry state, insufficient temperature resistance, and flammability in case of fire, which greatly limits its application in certain fields.
In recent years, ABS and PA blended alloys have attracted market attention. The addition of ABS can effectively improve the water absorption performance and notch toughness of PA. However, due to the existence of unsaturated double bonds in the molecular structure of ABS, the weather resistance of ABS / PA alloy materials Deterioration, prone to aging outdoors or under sunlight

Abstract

The invention provides a halogen-free flame-retardant fiberglass-reinforced PA (Polyamide)/ASA (Acrylonitrile Styrene Acrylate Copolymer) composite material. The halogen-free flame-retardant fiberglass-reinforced PA/ASA composite material is prepared from the following components in parts by weight: 20 to 65 parts of PA, 10 to 30 parts of an acrylonitile-styrene grafted acrylate rubber copolymer,10 to 25 parts of a flame retardant, 2 to 5 parts of a compatilizer, 10 to 30 parts of fiberglass, 3 to 8 parts of a toughening agent, 0.1 to 1 part of a nucleating agent, 0.1 to 1 part of a lubricating agent and 0.1 to 1 part of an antioxidant. According to the halogen-free flame-retardant fiberglass-reinforced PA/ASA composite material provided by the invention, compounding of the ASA and the PAis adopted, so that the water absorption performance of the PA is effectively improved, the material shrinkage performance is reduced, the size stability is remarkably improved, and meanwhile, good weather resistance and good aging resistance are given to the halogen-free flame-retardant fiberglass-reinforced PA/ASA composite material.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a halogen-free flame-retardant, glass fiber reinforced PA / ASA composite material and a preparation method thereof. Background technique [0002] Polyamide has become one of the top five engineering plastics due to its excellent mechanical strength, corrosion resistance, wear resistance and self-lubricating properties. Especially the glass fiber-reinforced and modified products are widely used in electric tools, automobile industry, machinery industry, sports equipment, office equipment and other fields. However, it has defects such as high water absorption, poor dimensional stability, insufficient toughness at low temperature and dry state, insufficient temperature resistance, and flammability in case of fire, which greatly limits its application in certain fields. In recent years, ABS and PA blended alloys have attracted market attention. The addition of ABS can effectively imp...
