Dyeable permanent antistatic flame-retardant polyolefin material as well as preparation method and application thereof

Abstract

The invention discloses a dyeable permanent antistatic flame-retardant polyolefin material and a preparation method thereof. The dyeable permanent antistatic flame-retardant polyolefin material comprises a polyolefin matrix, a flame retardant, a compatilizer and an antistatic agent, and the antistatic agent comprises a permanent antistatic agent and a nonionic antistatic agent. The polyolefin material has dyeable, permanent antistatic and flame-retardant properties, can meet the requirements of MT181-1988 standard mining pipes, and can also meet the requirements of standardized mines.

AI Technical Summary

Problems solved by technology

Existing mining plastics and their composite pipes have the following defects: 1. Polyolefin materials such as carbon black, graphene and carbon nanotubes that use carbon materials as antistatic agents are black, and only black pipes can be prepared by this material. And it cannot be dyed, which cannot meet the requirements of the current standardized mine construction for color marking of pipes; 2. The antistatic agent of pipes made of polyolefin materials modified by traditional migratory antistatic agents is easy to migrate, and the antistatic effect is easy to fade with time. Attenuation, the loss of antistatic performance is large, which is not conducive to the long-term safe use of pipes; 3. Plastic pipes and composite pipes with colored lines are difficult to identify due to the thin marking lines of the pipes, and the pipes marked with paint are painted by brushing and spraying. or dip coating on the surface of the product, it is easy to cause the paint to fall off due to friction and washing, it is not easy to mark for a long time, and it can only provide temporary or short-term antistatic

[0004] When the permanent antistatic agent is used to modify polyolefin, the dosage is relatively large. Although the polyolefin can be permanently antistatic, the compatibility between the permanent antistatic agent and polyolefin is poor, resulting in the deterioration of the modified polyolefin material. The mechanical properties are significantly reduced, making it difficult to apply to the mine environment

In addition, the price of permanent antistatic agent is high, and when it is used in large quantities, it will significantly increase the cost of pipelines
