[0028] The preparation method of described modified polylactic acid fiber comprises the steps:

[0029] (1) Rinse the kaolin once with deionized water, then put it into the calciner for calcining, and take it out for subsequent use after completion;

[0030] (2) Immerse the kaolin treated in step (1) into the silane coupling agent solution, and filter out after 30-35 minutes for later use;

[0031] (3) The kaolin, nano-silver, and polylactic acid slices processed in step (2) are mixed together, firstly mixed, and taken out after 50 to 55 minutes to obtain the mixed material for subsequent use;

[0032] (4) Put the compounded material obtained in step (3) into a twin-screw extruder for extrusion processing, and then carry out spinning processing after completion, and finally go through cooling, drawing, and cutting.

[0033] During the calcination treatment described in step (1), the temperature in the calcination furnace is controlled to be 800-850° C., and the treatment time...

Abstract

The invention discloses a wire harness protection piece, which belongs to the technical field of pressure-sensitive adhesives. The wire harness protection piece is particularly is formed by forming non-woven fabric composed of mixed fibers containing polypropylene resin fibers, modified polylactic acid fibers and modified basalt fibers into a preset shape. According to the invention, the componentcomposition of the wire harness protection piece is changed; the polypropylene resin fibers, the modified polylactic acid fibers and the modified basalt fibers are mixed to prepare the non-woven fabric, the use quality of the wire harness protection piece is effectively improved, the polypropylene resin fibers serve as a main body, the cost is reduced, the two kinds of modified fibers are added,and the overall strength, weather resistance and temperature resistance are improved; after the three fibers are mixed and woven into the non-woven fabric, the overall mechanical quality, the use stability and the like of the non-woven fabric are remarkably improved, and the protection on the wire harness is effectively enhanced.

Description

technical field [0001] The invention belongs to the technical field of pressure-sensitive adhesives, and in particular relates to a conductive pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] In recent years, high performance and high functionality have been developed centering on motor vehicles and electrical products. In order for various electronic devices such as automobiles and electric products to operate accurately, multiple electric wires are used for internal wiring of automobiles and electric products. Generally, these multiple wires are used in a wire harness. [0003] In the wire harness, a wire bundle composed of a plurality of electric wires is pre-assembled into a form required for wiring. For example, a wire harness is formed by forming necessary branches and attaching connectors to the ends thereof, and then wrapping a wire harness protector in various shapes such as a belt, a tube, or a sheet around the outer per...
