[0021] Nylon is dried in a drying hopper at 90-110°C for 3-4 hours, and the formula amount of nylon 6 (PA6), phosphorus-nitrogen structure halogen-free intumescent nylon flame retardant (HJ-1), toughening agent (HJ- 2) After mixing all kinds of additives evenly in the high-speed mixing bucket as required, add them from the mixing port until the temperature is set at 220-270°C, and the length-to-diameter ratio (L / D) is 32:1-40:1. The screw combination is vacuumized and granulated in a twin-screw extruder specified by the process to make a halogen-free glass fiber reinforced nylon 6 resin. The sampled material was dried at 90-110°C for 3-4 hours and then injection-molded into a standard sample for performance testing. The performance is shown in Table 2.

Abstract

The invention provides a halogen-free glass fiber reinforced nylon resin and a preparing method thereof. The material comprises the following raw materials with the weight percentage: 38-55 percent of nylon 66 or nylon 6, 17-30 percent of halogen-free intumescent nylon flame retardant of phosphorus-nitrogen structure, 4-8 percent of toughening agent, 25-35 percent of glass fiber and 0.5-1.5 percent of other promoters.

Description

technical field [0001] The invention relates to a halogen-free glass fiber reinforced nylon resin and a preparation method thereof. Background technique [0002] Nylon resin is the earliest developed engineering plastic. It has the advantages of toughness, wear resistance, solvent resistance, oil resistance, low melt viscosity, easy availability of raw materials, recyclability and high cost performance. The flame retardancy of nylon plastic without flame retardant is poor, which limits its application in many fields. The addition of flame retardant expands the application range of nylon plastic. The commonly used flame retardants are mainly halogen-antimony system flame retardants, among which bromine-based flame retardants are the main ones. The added bromine-antimony flame retardants improve the flame retardancy of the material to a certain extent, but the electrical properties of the material However, the performance is greatly affected. For example, compared with the tr...
