Abstract
The invention relates to a method for reducing a flow rate of polyethylene melt, which comprises the following process steps: A, preparation of auxiliary agents: taking 100 parts of polyethylene and 5-10 parts of polyethylene cross-linking agent; B, mixing: mixing the auxiliary agents at the room temperature; C, dilution: diluting the polyethylene according to a ratio of 100:1, putting 1 part of prepared auxiliary agents into 100 parts of polyethylene, and mixing; D, feeding: putting the well diluted mixture into an extruder for granulation and extrusion, thereby achieving the effect of reducing the flow rate of the polyethylene melt. The method has the advantages of simple process, easy operation and no pollution, and can realize the industrial mass production; and the method can reduce the flow rate of the polyethylene melt with the high melt index, so that the polyethylene melt can be used as a raw material suitable for pipeline production. The invention can be widely applied in product production with the extrusion, emptying, film blowing, drawing and the like of the polyethylene melt.
Description
Technical field
The present invention relates to a kind of method that reduces the plastic melt flow velocity, particularly relate to a kind of method that reduces flow rate of polyethylene melt.
Background technology
Many all institutes, with the injected high density polyethylene that existing method is produced, melting index is too high, and melt flow is too fast, can not satisfy the requirement as the production duct products, and how reducing flow rate of polyethylene melt is a unsolved so far difficult problem.
Summary of the invention
Purpose of the present invention is exactly to concentrate on studies through the contriver in order to remedy the deficiencies in the prior art, checking repeatedly, provide a kind of novel, technology simple, easy handling, is used to reduce the method for flow rate of polyethylene melt.
To achieve these goals, a kind of method that is used to reduce flow rate of polyethylene melt that the present invention is alleged, its technical scheme is:
The technical process of this method is as follows:
A, the preparation of auxiliary agent thing: get 100 parts of polyethylene, 5～10 parts of polyvinyl crosslinking agents, standby;
B, mixing: mix above-mentioned auxiliary agent thing standby at normal temperatures;
C, dilution: by 100: 1 dilution polyethylene, promptly get 100 parts of polyethylene, drop in 100 parts of polyethylene for 1 part with the above-mentioned auxiliary agent thing for preparing, and mix;
D, last machine: granulation in the above-mentioned mixture input forcing machine that mixes is extruded, flow rate of polyethylene melt is reduced.
Polyvinyl crosslinking agents of the present invention is together with---diperoxy tertiary butyl---3,3,5---trimethyl-cyclohexane.
Polyvinyl crosslinking agents of the present invention is 8 parts.
A kind of method that is used to reduce flow rate of polyethylene melt that the present invention is alleged, its beneficial effect is: novel, technology is simple, easy handling, pollution-free, can form industrialized mass production; Adopt the present invention can make the injected high density polyethylene of high fusion index 8～11 by little cross-linking method flow rate of polyethylene melt be reduced, melting index reduces to 0.5～1.5, becomes the raw material that is fit to produce pipeline.The present invention can be widely used in the products production of purposes such as the extruding of polyethylene melt, hollow, blown film and wire drawing.
