preparation example Construction

[0014] The invention provides a method for preparing a flat cable resistant to flexing and bending fatigue, wherein the preparation method includes: extending and arranging a plurality of conductors in the horizontal direction to form a cable, and After a sheet is placed on the lower surface, carbon fiber powder is filled between multiple conductors, and a sheet is covered on the upper surface of the cable, and then hot-pressed to obtain a flex-resistant and bending-fatigue-resistant A ribbon cable; wherein said sheet is made by the following steps:

[0015] 1) mixing starch and water to obtain a suspension;

[0016] 2) At a temperature of 90-100°C, add the above-mentioned suspension and calcium chloride to the styrene-butadiene emulsion and mix, then let it stand and filter to obtain flocs, and put the above-mentioned flocs at a temperature of 70-80°C Dry under certain conditions to obtain a composite material;

[0017] 3) Adding a silane coupling agent to the above-mention...

preparation example 1

[0030] 1) Mix 0.2 parts by weight of starch and 100 parts by weight of water to prepare a suspension;

[0031] 2) At a temperature of 90°C, add 50 parts by weight of the above suspension and 0.5 parts by weight of calcium chloride to 100 parts by weight of the styrene-butadiene emulsion, mix them, let stand, filter to obtain flocs, and then rinse with water 3 times, drying the above-mentioned flocs at a temperature of 70°C to obtain a composite material;

[0032] 3) Add 0.3 parts by weight of KH550 silane coupling agent to 100 parts by weight of the above-mentioned composite material and stir and mix at a temperature of 100° C., then add 5 parts by weight of carbon black, 1 part by weight of graphene oxide, vulcanizing agent and After the accelerator is mixed and smelted, it is compressed into a tablet to obtain a sheet A1.

preparation example 2

[0034] 1) 0.5 parts by weight of starch and 100 parts by weight of water are mixed to obtain a suspension;

[0035] 2) At a temperature of 100°C, add 70 parts by weight of the above suspension and 1 part by weight of calcium chloride to 100 parts by weight of the styrene-butadiene emulsion, mix them, let stand, filter to obtain flocs, and then rinse with water 3 times, drying the above-mentioned flocs at a temperature of 80°C to obtain a composite material;

[0036] 3) Add 0.5 parts by weight of KH550 silane coupling agent to 100 parts by weight of the above-mentioned composite material and stir and mix at a temperature of 120° C., then add 10 parts by weight of carbon black, 2 parts by weight of graphene oxide, vulcanizing agent and After the accelerator is mixed and smelted, it is compressed into a tablet to obtain a sheet A2.

Abstract

The invention discloses a flexural and bending fatigue resistant ribbon cable and a preparation method thereof. The method is characterized in that after multiple conductors are arranged and extend inthe horizontal direction to form a flat cable, after a sheet is placed on a lower surface of the flat cable, after carbon fiber powder is filled among the multiple conductors, an upper surface of theflat cable is covered by a sheet, and the sheet is then hot-pressed to obtain the flexural and bending fatigue resistant ribbon cable; the sheet is obtained by following steps, 1), starch and the water are mixed to prepare suspension; 2), under the temperature of 90-100 DEG C, the suspension and calcium chloride are added to butylbenzene emulsion, mixed, then allowed to stand and filtered to obtain floc, and the floc is dried at the temperature of 70-80 DEG C to obtain a composite material; and 3), silane coupling agent is added to the composite material to stir and mix, and carbon black, graphene oxide and processing aid are mixed and smelted and then tableted to form the sheet. The method is advantaged in that bending resistant property is achieved.

Description

technical field [0001] The invention relates to the field of flat cable materials, in particular to a flat cable resistant to flexing and bending fatigue and a preparation method thereof. Background technique [0002] Ribbon cable, customarily refers to strip-shaped parallel multi-core wires, such as gray cable, rainbow cable, high temperature cable, etc. Broadly speaking, ribbon cables should also include cable varieties such as flexible printed wires and flexible flat cables. Due to the flat structure and good performance of the ribbon cable, it is widely used in national defense, aerospace, digital communication, robotics, medical equipment, electronic equipment and other fields. [0003] However, because of its flat structure, it is often bent during use, and the bent cross-section is larger than that of a general round cable, making it easier to be bent, and It is more prone to problems such as cracking or even breaking.
