A kind of polyoxymethylene fiber for dredging static electricity and preparation method thereof

Abstract

The invention provides polyoxymethylene fibers capable of conducting static electricity and a preparation method of the polyoxymethylene fibers. The polyoxymethylene fibers capable of conducting the static electricity are characterized by being prepared from the following components in parts by mass: 100 parts of polyoxymethylene, 1-10 parts of conductive carbon black grafted with formal on the surface, 0.1-10 part of an antioxidant and 0.1-10 parts of a bulking agent. The polyoxymethylene fibers prepared by the invention still have good durable and static electricity conducting effects under low humidity, and usage and application fields of the polyoxymethylene fibers are expanded. Compared with a method for directly commixing, fusing and spinning the conductive carbon black and the polyoxymethylene, the conductive carbon black in the polyoxymethylene fibers capable of conducting the static electricity, prepared by the preparation method provided by the invention, is grafted with formal short chains, so that the conductive carbon black has relatively good compatibility with a polyoxymethylene base body; and the dispersion is relatively uniform and the anti-static electricity effect is relatively excellent.

Description

technical field [0001] The invention belongs to the field of chemical product preparation, and in particular relates to a polyoxymethylene fiber for dredging static electricity and a preparation method thereof. Background technique [0002] Polyoxymethylene is an engineering plastic with excellent performance, which has high strength and hardness, and can maintain excellent performance in a wide range of temperature and humidity, including corrosion resistance, high strength and good dimensional retention Rate, etc., so polyoxymethylene is also called "plastic steel", which is widely used in many fields such as mechanical products and auto parts. Using polyoxymethylene as raw material, the prepared polyoxymethylene fiber has high strength and high modulus, excellent chemical resistance and creep resistance, and can be widely used in reinforcing fibers of cement-based, plastic, rubber and other substrates. And cables, fishing nets, filters, etc. However, due to the characte...

AI Technical Summary

Problems solved by technology

However, amines, amides and quaternary ammonium salts themselves do not have good conductivity, and only have certain conductivity after ionization occurs in a high-humidity environment. There is no essential difference in the method of blending and spinning the electrostatic agent and the spinning raw material, and its antistatic effect will be affected by the ambient humidity

Moreover, the polyoxymethylene fiber itself has poor hydrophilicity, and it is difficult to absorb the moisture in the environment to meet the demand of the antistatic agent for moisture, which greatly limits the antistatic effect of the hydrophilic antistatic agent in the polyoxymethylene fiber.
