Shape.PE has excellent resistance to most of characteristics lived with chemicals for industrial use.Some kinds of chemicals can produce chemical corruption
Erosion, such as corrosive oxidation agent (concentrated nitric acid), aromatic hydrocarbon (dimethylbenzene) and halogenated hydrocarbon (carbon tetrachloride).
At present, conventional PE Gas Pipes are mainly made of high density polyethylene (HDPE), but these pipeline compositions are reasonable not enough, are caused
Make intensity, rigidity, modulus of gas pipeline etc., all do not reach gratifying effect.
CN201510281792 has invented a kind of enhanced PE Gas Pipes of use clay nanocomposites, but this method institute
Organic coupling modifier is not carried out with clay nanocomposites, in actual applications, clay nanocomposites and PE matrix phases
Capacitive is short of, and causes enhancing effect limited, and the present invention is filled out using maleic anhydride grafted ethene-acetate ethylene copolymer as inorganic
The macromolecular coupling compatibility agent of material and PE matrixes, can effectively facilitate the compatibility of inorganic filler and base polyethylene, improve nothing
Enhancing effect of the machine filler in system, the addition of maleic anhydride and initiator is remarkably improved crosslinked action, further improves
The intensity and toughness of tubing.
The content of the invention
In view of the shortcomings of the prior art, in order to improve the intensity and toughness of conventional PE Gas Pipes, there is provided a kind of letter by the present invention
Single, rational high-strength toughness reinforcing high density PE Gas Pipes.
The present invention solves its technical problem and takes following technical scheme to realize：

The treated inorganic filler of ester coupling agent, zirconium ester coupling agent, boric acid ester coupler.
Described initiator is selected from cumyl hydroperoxide, cumyl peroxide, benzoyl peroxide, benzoyl peroxide first
One or more in the acyl tert-butyl ester, methyl ethyl ketone peroxide, azodiisobutyronitrile, ABVN.
A kind of preparation method of high-strength toughness reinforcing high density PE Gas Pipes, comprises the following steps：
(1) mix：The raw material of above-mentioned parts by weight is well mixed and is put into kneading machine, is heated while stirring, temperature is maintained at
70-80 DEG C, after 10min, stop stirring, obtain tubing premix；
(2) granulate：Tubing premix is put into comminutor to be granulated, cooling obtains granular tubing batch mixing after drying；
(3) it is molded：Granular tubing batch mixing is put into extruder shaping, product is produced after traction, coiling, punching, cleaning.
Advantages and positive effects of the present invention are：
The high-strength toughness reinforcing high density PE Gas Pipes of the present invention are grafted second by high density polyethylene (HDPE), inorganic filler, maleic anhydride
Alkene-
Acetate ethylene copolymer, maleic anhydride, initiator composition, maleic anhydride grafted ethene-acetate ethylene copolymer can
With effective
Promote the compatibility of inorganic filler and polyethylene, improve enhancing effect of the inorganic filler in system, maleic anhydride
And initiation
The addition of agent is favorably improved crosslinked action, further improve tubing intensity and toughness, the Gas Pipe have with
Lower advantage：
1st, high-strength and high ductility, anti-stress cracking is good；2nd, wearability is good；3rd, pliability is good；4th, service life is long；With non-
Chang Youyi economic and social benefit.
