Abstract

The invention discloses a halogen-free and flame-retardant glass fiber reinforced nylon composite and a preparation method thereof, and belongs to the field of production of halogen-free and flame-retardant reinforced nylon and polyphenylene sulfide composites. The halogen-free and flame-retardant glass fiber reinforced nylon composite is prepared from 25-50 parts of nylon, 5-15 parts of polyphenylene sulfide, 10-30 parts of glass fiber, 15-25 parts of a halogen-free and flame-retardant mixture, 1-5 parts of a compatilizer, 0.1-0.3 parts of an antioxidant and 0.1-0.5 parts of a lubricant by mixing and extruding. The halogen-free and flame-retardant mixture is prepared from flame-retardant red phosphorus masterbatch, melamine cyanurate and organic nano-montmorillonite in a mass ratio being5:1:1-5:3:3 by compounding. By compounding polyphenylene sulfide and nylon, hardness, wear resistance and creep resistance of the material are improved; meanwhile, flame retardance of the composite isimproved by the halogen-free and flame-retardant mixture, oxygen index reaches 28 or higher, and finally, the halogen-free and flame-retardant glass fiber reinforced nylon composite product with excellent combination property is obtained.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a halogen-free flame-retardant glass fiber reinforced nylon composite material and a preparation method thereof. technical background [0002] In view of the current electronic and electrical market, in order to meet market needs, higher requirements are put forward on the strength, rigidity, impact resistance, flame retardancy and other aspects of engineering plastic products. [0003] Materials such as reinforced nylon and flame-retardant reinforced nylon have been developed one after another. However, in order to ensure the flame retardancy of the product, the mechanical properties of the material are lost to a certain extent. [0004] As a new high-performance engineering plastic, polyphenylene sulfide has the characteristics of high strength, good wear resistance, excellent creep resistance, high temperature resistance, chemical resistance, f...
