Conductive and antistatic nylon

Abstract

The invention discloses a conductive and antistatic nylon which adopts polyamide resin as basic material and adds nano inorganic filling material, conductive carbon black, a lubricating agent, a surface processing agent and an antioxidant and the like; the part by weight ratio of all the components is as follows: 60 parts to 98 parts of polyamide resin, 1 part to 15 parts of nano inorganic filling material, 5 parts to 30 parts of conductive carbon black, 0.1 part to 1.0 part of lubricating agent, 0.1 part to 1.0 part of surface processing agent and 0.1 part to 0.5 part of antioxidant; the invention adds the conductive carbon black in the polyamide resin to improve the conductive effect of the material, reduces the using amount of the carbon black under the premise of guaranteeing the same conductivity and antistatic electricity and effectively improves the cost performance of the material, effectively improves the dispersion of the carbon black, and reduces the 'percolation threshold' of plastic; and the nano material is added into the nylon and has the effect of a nucleating agent, which has obvious strengthening and toughening effects to matrix resin and improves the comprehensive performance of the product.

Description

technical field [0001] The invention relates to a conductive engineering plastic, in particular to a conductive and antistatic nylon. Background technique [0002] As a kind of polymeric polymer materials, engineering plastics have the characteristics of high degree of polymerization and poor molecular polarity. Generally, the surface resistivity of engineering plastics is greater than 10 12 Ω, in modern industrial production and daily life, electrostatic hazards often cause heavy losses and disasters. Conductive and antistatic plastics can effectively prevent static electricity on the surface of polymers and prevent safety accidents. [0003] There are many classifications of composite conductive polymer materials. According to the difference in resistance value, it can be divided into: semi-conductor, static electricity remover, conductor, high conductor; according to the difference of conductive filler, it can be divided into: antistatic agent system, Carbon-based, metal...

AI Technical Summary

Problems solved by technology

[0005] At present, in the process of using carbon black to make conductive plastics, conductive carbon black, metal powder, carbon fiber, etc. are mainly used for compounding, but metal powder has a great impact on the overall performance of the material and is expensive; carbon fiber is expensive, mass-produced, and marketable.

Therefore, the market competitiveness of using conductive carbon black, metal powder, and carbon fiber to prepare conductive plastics is poor.
