Example 5 in polypropylene wax modified polyester fiber, the acrylic resin melt is replaced by ethyl cellulose solution with the same quality, compared with example 1, the tensile strength of the isolation preservative film prepared in example 5 is smaller than that of example 1, and the difference between the isolation preservative film and the initial tensile strength after repeated use is larger than that of example 1; it is explained that the ethyl cellulose solution can bond the polypropylene wax on the surface of the polyester fiber, but the ethyl cellulose has a higher melting point, so that the ethyl cellulose cannot be melted in the extrusion molding process, and the bonding compatibility of the polyester fiber, the glass fiber and the polyethylene cannot be improved, thereby influencing the tensile strength of the finished product isolation preservative film.
Compared with example 1, the tensile strength of the isolation preservative film prepared in example 6 is smaller than that of example 1, and the difference between the isolation preservative film and the initial tensile strength after repeated use is larger than that of example 1; the glass fiber is treated by the aminosilane coupling agent, so that the bonding compatibility of the glass fiber, the polyester fiber and the polyethylene can be improved, and the tensile strength of the isolation preservative film is improved.
In the example 7, the polypropylene wax modified glass fiber is replaced by the ethyl cellulose solution with the same quality to replace TPU melt, compared with the example 1, the tensile strength of the isolation preservative film prepared in the example 7 is smaller than that of the example 1, and the difference between the isolation preservative film and the initial tensile strength after the isolation preservative film is repeatedly used is larger than that corresponding to the example 1; the ethyl cellulose solution has a bonding effect and can bond the polypropylene wax on the surface of the glass fiber, but the ethyl cellulose has no toughness of TPU, and the bonding compatibility of raw materials such as the glass fiber and polyethylene cannot be improved, so that the tensile strength of the finished product isolation preservative film is influenced.
In the embodiment 8, the POE particles are replaced by TPU particles with the same mass, compared with the embodiment 1, the tensile strength of the insulation preservative film prepared in the embodiment 8 is smaller than that of the embodiment 1, and the difference between the insulation preservative film and the initial tensile strength after repeated use is larger than that of the embodiment 1; the TPU particles, the acrylic resin and the POE particles are matched, so that the density of the crosslinked structure of the isolation preservative film can be further improved, and the tensile strength of the isolation preservative film is improved.
In example 9, the TPU particles in the filler particles are commercially available TPU particles, no silicon nitride is added in the TPU particles, the POE particles are commercially available POE particles, and no silicon nitride is added in the POE particles, compared with example 1, the insulation preservative film prepared in example 9 has a tensile strength smaller than that of example 1, and the insulation preservative film has a difference value with the initial tensile strength larger than that of example 1 after repeated use; the method shows that no silicon nitride is added, so that the strength of the filler is low, and the tensile strength of the finished product isolation preservative film is affected.
As can be seen from the combination of example 1 and comparative examples 1-2 and the combination of table 1, the comparative example 1 has no polypropylene wax modified fiber material and filler particles added to the raw material, and compared with example 1, the barrier fresh-keeping film prepared in comparative example 1 has a tensile strength smaller than that of example 1, and the barrier fresh-keeping film has a difference from the initial tensile strength greater than that of example 1 after repeated use; the polypropylene wax modified fiber material and the filler particles are matched, so that the tensile strength of the finished product isolation preservative film can be improved.
Compared with the example 1, the isolation preservative film prepared in the comparative example 2 has the tensile strength smaller than that of the example 1, and the difference between the isolation preservative film and the initial tensile strength after repeated use is larger than that of the example 1, the fold area is larger than that of the example 1, and the hollowness number is larger than that of the example 1; the polypropylene wax is used for treating fibers, so that the attaching effect of the isolation preservative film can be improved, and wrinkles and hollows are reduced.
The present embodiment is only for explanation of the present application and is not to be construed as limiting the present application, and modifications to the present embodiment, which may not creatively contribute to the present application as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present application.
