Problems solved by technology

However, the oxygen index of polyethylene is 17.0-17.5, which is a flammable material, which is easy to cause fire and is restricted in many application fields.
At the same time, since polyethylene is an electrical insulating material, its surface is prone to static electricity, which brings safety hazards to actual production

Abstract

The invention discloses a flame-retardant antistatic bifunctional modified polyethylene composite material and its preparation method. The flame-retardant antistatic bifunctional modified polyethylene composite material comprises, by mass, 50-80% of polyethylene, 12-25% of a compounded flame retardant, 2-5% of an antistatic master batch, 0.1-2% of a lubricant, 0.1-0.6% of a primary antioxidant and 0.1-0.5% of an auxiliary antioxidant. Compared with polyethylene composite materials in the prior art, the flame-retardant antistatic bifunctional modified polyethylene composite material has the advantages of very good halogen-free flame retardation property (oxygen index reaching above 28), UL94-0 flame retardation grade standard reaching, small smoke quantity, non-toxicity, no fused drop phenomenon, good dispersibility, good molding processability, high antistatic property, good durability, and surface resistance reaching 10<7>-10<9>omega.m.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant and antistatic bifunctional modified polyethylene composite material and a preparation method thereof. Background technique [0002] Polyethylene (PE) has the characteristics of light weight, non-toxicity, easy molding and processing, and high cost performance. It is widely used in many fields and is the second most used general-purpose plastic in the world. However, the oxygen index of polyethylene is 17.0-17.5, which is a flammable material, which is very easy to cause fire and is restricted in many application fields. At the same time, because polyethylene is an electrical insulating material, its surface is prone to static electricity, which brings safety hazards to actual production. Therefore, it is of great significance to modify polyethylene for flame retardancy and antistatic properties. Contents of the invention [0003] The object of the...
