Problems solved by technology

[0003] In signal transmission, noise has a great influence on signal transmission, which will lead to distortion of signal transmission, which will greatly reduce the performance of electronic products. At present, the anti-noise materials for signal cables on the market are all made of cotton fibers. Cover the conductive thread to achieve anti-noise, while the cotton yarn has poor anti-noise ability and cannot meet the requirements of electronic products for signal cable transmission signal quality

Abstract

The invention discloses a preparation method of a fiber composite material for signal cables, which is characterized by comprising the following steps: (1) preparing polyvinyl chloride (PVC) resin fibers; (2) preparing flax fibers, immersing the prepared flax mixed fibers in a 2% sodium hydroxide solution for 1-2 hours, cleaning with clear water, treating in an acid bath for dealkalization, cleaning with deionized water until the cleaning solution is neutral, finally putting in a baking oven, and baking at 100-120 DEG C for 0.5-1 hour for later use; (3) preparing a fixing solution; and (4) by using the prepared PVC fibers as a base film, fixing the prepared flax fibers to the PVC fibers by using the prepared fixing solution, putting in a baking oven, baking at 100-120 DEG C for 0.5-1 hour, and naturally cooling to obtain the fiber composite material for signal cables. The invention also discloses a product prepared by the method.

Description

technical field [0001] The invention relates to the field of signal cable preparation, in particular to a method for preparing a fiber composite material for signal cables, and a product prepared by the method. Background technique [0002] There are many sources of noise. Its impact and harm are great, so it is very meaningful to research and develop anti-noise materials. The anti-noise performance of the material is related to the sound absorption, surface density, and damping properties of the material itself. Traditional anti-noise materials generally improve the anti-noise performance by increasing the surface density. big impact. Composite materials have received extensive attention in the research and application of anti-noise materials due to their characteristics such as composite effects and interface effects. [0003] In signal transmission, noise has a great influence on signal transmission, which will lead to distortion of signal transmission, which will grea...
