Description
Technical field
The present invention relates to a kind of processing of plastic properties-correcting agent and method of use of being used for, particularly relate to a kind of modifier and method of use thereof that is used for the useless tube material of low pressure polyethylene.
Background technology
As everyone knows, the useless tube material processing means of existing low pressure polyethylene is outmoded, technology falls behind, and the product physical and chemical performance of producing is lower, second-rate, can not satisfy the demands of consumers, and also can not adapt to the demand of market development, thereby limits its range of application.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of above-mentioned background technology concentrating on studies and, a kind of modifier and method of use thereof that is used for the useless tube material of low pressure polyethylene is provided through the contriver through producing actual repeated validation.
To achieve these goals, technical scheme of the present invention is such:
A kind of modifier that is used for the useless tube material of low pressure polyethylene provided by the invention, described modifier comprises following component and weight part thereof: chlorinatedpolyethylene 1.1～2.1.
In technique scheme, described modifier comprises following component and weight part thereof: chlorinatedpolyethylene 1.6.
A kind of method of use that is used for the modifier of the useless tube material of low pressure polyethylene provided by the invention; May further comprise the steps: step 1, the useless tube material water of low pressure polyethylene is cleaned; Remove foreign material and dust; To remove the useless tube material of clean low pressure polyethylene again and cut into the close material of size, subsequent use; The melt flow index of step 2, the useless tube material of detection low pressure polyethylene, setting melt flow index M1 is 0.5～3.0; Step 3, the useless tube material of above-mentioned subsequent use low pressure polyethylene is dropped in the mixing machine; Again in the preparation of following ratio: the low pressure polyethylene tube material that gives up: chlorinatedpolyethylene=100: 1.1～2.1; Mixing drops in the mixing machine, and start is 10～15 minutes under normal temperature condition, shuts down; Step 4, the above-mentioned mixture discharging packing that processes get final product.
In technique scheme, when said melt flow index M1=0.5～0.8, the useless tube material of low pressure polyethylene then: chlorinatedpolyethylene=100: 1.1; When said melt flow index M1=0.8～1.5, the useless tube material of low pressure polyethylene then: chlorinatedpolyethylene=100: 1.4; When said melt flow index M1=1.5～2.0, the useless tube material of low pressure polyethylene then: chlorinatedpolyethylene=100: 1.6; When said melt flow index M1=2.0～3.0, the useless tube material of low pressure polyethylene then: chlorinatedpolyethylene=100: 2.1.
The present invention is alleged is used for the modifier and the method for use thereof of the useless tube material of low pressure polyethylene, has following beneficial effect: novel, technology rationally, processing is simple, easy to use, can realize requirement of industrialized batch production.The present invention can improve the physical and chemical performance of the useless tube material of low pressure polyethylene effectively, reduces melt flow index, makes material increase toughness and intensity, has the PP Pipe Compound of squeezing effective way thereby become.The present invention can be widely used for the modification processing of the useless tube material of low pressure polyethylene.
