Problems solved by technology
The electrostatic materials commonly used in the market now mainly add some low-molecular-weight antistatic agents to the materials, which mainly rely on the precipitation of molecules to form a hydrophilic layer on the surface of the material to produce electrostatic effects, but its main disadvantages are that the electrostatic time is short and it is not washable. The electrostatic effect will be lost in a short time

Abstract
The invention provides a PA permanent antistatic material, a preparation method and applications thereof. The PA antistatic material is prepared from the following components in percentage by weight: 60 to 80% of nylon, 18 to 38% of flame-retardant static-conductive dissipative type master batch, and 2 to 6% of flexibilizer. The PA antistatic material is prepared by blending and mixing nylon, flame-retardant static-conductive dissipative type master batch, and flexibilizer, and then extruding the mixture. After modification, the provided PA antistatic material can reach the high oxygen index (extremely difficulty in burning) V0 grade; the volume resistivity is 10<6> to 10<8> [ohm], the surface resistivity is 10<6> to 10<9> [ohm], the static decay time is more than 200 seconds, the permanent antistatic effect is good, the PP material is flame retardant, the flame retardant performance is not dependant on the humidity and temperature, and the PP material can be widely used in the fields such as microelectronics, electric appliance, medicine, textile, printing, mining, military equipment, fire fighting, initiating explosive device, petroleumchemical engineering, train, automobile, airplane, package, transportation, and the like. The PP material can effectively control the all-pervasive harm caused by static and has an excellent permanent static resistant performance and flame retardant effect.
Description
technical field [0001] The invention belongs to the field of preparation of flame-retardant and static-conductive materials, and relates to a PA electrostatic material and a preparation method and application thereof, in particular to a PA permanent electrostatic material and a preparation method and application thereof. Background technique [0002] Nylon composite materials have been widely used in many fields such as automobiles, aircrafts, electronic appliances, petrochemicals, medical treatment, textiles, packaging, and transportation. However, as a member of plastics, it has defects that cannot be ignored, that is, it is easy to generate static electricity and stick to dust. In severe cases, static electricity hazards may cause major losses and disasters to life or production. [0003] At present, to prevent the accumulation of static electricity on the surface of polymers, the main methods are air ion wind method, metal grounding method, electrostatic field environmen...
