Abstract

The invention relates to the field of polyamide compound, in particular to a nylon 66 compound capable of use for weaving glass-fiber-free shuttles. The nylon 66 compound is prepared with raw materials according to the following mass ratios: 40-67% of nylon 66 slices, 15-30% of nylon 66 slices, 1-5% of ultra-high molecular weight polyethylene, 15-30% of compatilizer, 0.1-0.5% of antioxygen and 1-10% of lubricant. The preparation method of the nylon 66 compound comprises the following steps: 1. weighting the raw materials; 2. putting all the raw materials in a high mixing machine for mixing; and 3. putting the raw material mixture into a double-screw extruder for extrusion and pelleting. In the invention, nylon 66 resin is used as the base material, the ultra-high molecular weight polyethylene is used, and no glass fiber is used. The invention has the advantages of high fluidity, strong impact resistibility, high strength, wearability, stable dimension, smooth and clean appearance, no glass fiber exposure and antistatic performance.

Description

technical field [0001] The invention relates to the field of polyamide compositions, in particular to a nylon 66 composition that can be used for textile non-glass fiber shuttles, and the nylon 66 composition can be used for injection molding textile shuttles. Background technique [0002] Polyamide is commonly known as nylon (Nylon), and its English name is Polyamide (referred to as PA). It is a general term for thermoplastic resins containing repeated amide groups - [NHCO] - in the main molecular chain. Including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output, and wide application. Its name depends on the specific number of carbon atoms in the synthetic monomer. [0003] Nylon is the most important engineering plastic, and its output ranks first among the five general-purpose engineering plastics. Nylon is a polyamide fiber (nylon). It can be made into long or short fibers. [0004] Nylon was developed by an...
