Description

Grafted polyethylene PUR and preparation method for steel wire mesh frame PE pipes
Technical field
The present invention relates to PUR field, and in particular to grafted polyethylene PUR and system for steel wire mesh frame PE pipes Preparation Method field.
Technical background
The poly- PE multiple tubes of steel wire mesh frame, be using high-tensile steel wires left-and-right spiral shaping mesh skeleton as reinforcement, with Height density polyethylene (HDPE) is matrix, and is closely connected steel wire mesh frame and inside and outside hdpe layer with PUR It is connected together.
But the PUR and the shear strength of steel wire commonly used on the market at present often only have 10MPa or so, Wu Fashi The use environment of existing high shear strength requirement.
Although there is a kind of grafting PUR product in the market, it is possible to increase the shear strength of PUR and steel wire, But because pursuing high grafting rate, the product degree of cross linking is caused to increase so that the mobility of product reduces, gel content increase, hot melt The persistence of the peel strength of glue declines.When its reason is initiator concentration increase, the number of free radical increase in reaction, coupling The increase of terminating reaction degree, cross-linking reaction are just occupied an leading position.
The content of the invention
The scope of the present invention is only by claims defined, not by the old of this section content of the invention in any degree State and limited.
In view of the above-mentioned problems, there is high-adhesive-strength with steel wire it is an object of the invention to provide a kind of, and product flows The excellent grafted polyethylene PUR of property, its shear strength >=16MPa with steel wire.
For the grafted polyethylene PUR of steel wire mesh frame PE pipes, its technical scheme is：
100 parts of carrier is compounded, by HDPE：POE：LDPE：LLDPE is according to 5:1:1:3 mass fraction ratio is compounded；
0.1~0.3 part of composite initiator, by cumyl peroxide (DCP) and the double (peroxidating of 2,5- dimethyl -2,5- The tert-butyl group) hexane (BPDH) is according to 1:1~1:3 mass fraction ratio is compounded；
The quality parts ratio of 1~3 part of maleic anhydride, composite initiator and maleic anhydride is 1:10.
For the grafted polyethylene PUR of steel wire mesh frame PE pipes, its preparation method is：
(1) material is well mixed by high-speed mixer, then the two-way parallel double-screw by screw diameter for 75mm Extruding pelletization forms；
(2) draw ratio of two-way parallel double-screw extruder is 44:1, its screw combinations is from left to right followed successively by：56/ 56A、96/96、96/96、72/72、72/72、72/72、72/72、72/72、72/72、72/72、72/72、56/56、56/56、 K30/7/72、K45/5/56、72/72、56/56、K45/5/56、K45/5/56、56/56、56/56、K45/5/56、K90/5/ 56、L45/5/56、96/96、96/96、72/72、72/72、K45/5/56、K45/5/56、K45/5/56、56/56、72/72、 K45/5/56、K90/5/56、L28/56、28/28、96/96、96/96、96/96、72/72、72/72、36/72、36/36、56/ 56th, 56/56,56/56,56/56, screw combinations overall length 3176mm；A in 56/56A represents the starting that the threaded block is the screw rod Element；72/72 expression helical pitch is 72mm, the forward screw thread block that length is 72mm；K30/7/72 represents that stagger arrangement angle is 30 °, 7 and pinched Close disk, the positive kneading block that length is 72mm；L45/5/56 represent stagger arrangement angle be 45 °, 5 kneading disks, length be 56 it is reverse Kneading block.Other data are by that analogy.
(3) processing temperature of each warm area be 50 DEG C, 120 DEG C, 190 DEG C, 190 DEG C, 190 DEG C, 190 DEG C, 190 DEG C, 190 DEG C, 190 DEG C, 190 DEG C, 210 DEG C, screw speed 400r/min, extrusion electric current is 320A, and vacuum row waves pressure >=-0.08Mpa, with Clean unreacted free maleic anhydride is excluded as far as possible；
The beneficial effects of the invention are as follows：Compared with prior art, grafted polyethylene PUR of the invention has bonding strong The characteristics of degree is high, bonding persistence is strong, product mobility is excellent.The PUR is a kind of high-performance adhesives, belongs to HDPE It is material modified, it can be fused into one completely in a heated condition with HDPE, while its extremely strong adhesive property, due to this PUR Use, successfully solve the problems, such as between steel wire and polyethylene can not strong bond, grafted polyethylene of the invention hot melt The shear strength of glue and steel wire can reach more than 16Mpa, so, there is very excellent composite effect.
