Description
Technical field
The present invention relates to the hollow manufacture fields of polyethylene, and in particular to a kind of fuel oil drum polyethylene composition and its system
Preparation Method.
Background technology
Fuel oil drum usually has two kinds of metal and plastics.Manufacture metal fuel oil drum needs cutting, punching press, welding, spray painting etc.
Process, and to include attachment may be used hollow blow molding one-pass molding with plastic fuel oil drum, have simple process, efficient, production
Period short advantage, and cost can reduce by 1/3.Plastic fuel oil drum want substituted metal fuel oil drum it is necessary to have impact resistance,
The not performances such as easy to leak, fire-retardant, antistatic.
One of material of hollow blow molding plastic fuel oil drum is high density polyethylene (HDPE).For producing fuel oil drum
HDPE generally requires higher molecular weight, to ensure the preferable rigidity of product and creep resistance, while should also have resistance to punching
Hit, be corrosion-resistant, resisting environmental stress and cracking, barrier, excellent performances and the preferable processing performance such as antistatic.HDPE is high resistance
Rate insulating materials easy tos produce accumulation of static electricity during its processing and use, causes electrostatic precipitation or even static discharge etc. no
Good phenomenon.Inflammable oil is contained in fuel oil drum, static discharge easily causes burning and even explodes.Therefore, fuel oil drum is produced
HDPE resin, it is necessary to have good antistatic property.
It is conventional means that antistatic agent is added in HDPE.Make the surface resistivity of HDPE by the 10 of pure material14Ω is reduced to
1010Ω at least needs the antistatic agent for adding 10%-30%, and which not only adds material costs, due also to a large amount of antistatic
The addition of agent reduces the mechanical property of material.Therefore, it is necessary to the additive effect and dosage to antistatic agent are studied,
Develop a kind of long-acting antistatic HDPE compositions of low cost.
Invention content
The object of the present invention is to provide a kind of fuel oil drum polyethylene composition and preparation method thereof, fuel oil drum gathers
Vinyl composition is hollow molding, has permanent antistatic performance, and ensure the mechanical property of material.
A kind of fuel oil drum polyethylene composition of the present invention, is made of the raw material of following parts by weight：
