Problems solved by technology

The Chinese patent application number 99114635.2 discloses a synthetic fiber paper made of polyaramid synthetic fiber, which has certain advantages such as high temperature resistance, high strength, and low deformation, but its disadvantages are: because of its good The insulation performance of paper is non-thermal, non-conductive, poor fire resistance, and anti-oxidation and fatigue resistance can not meet some special purposes; and the Chinese patent application number 94115515.3 discloses synthetic fibers using polyacrylonitrile-based carbon fibers as raw materials Paper, which has the advantages of stable conductivity, high strength, bendability, and small specific gravity, but its disadvantages are: because it contains a large amount of plant fibers, it is not resistant to water, high temperature, oxidation resistance, corrosion resistance, and poor fatigue. and other shortcomings
At present, this kind of synthetic fiber paper has not been reported at home and abroad.

Embodiment 1

[0045] Prepare the present embodiment 1 synthetic fiber paper in the following proportions:

[0046] Carbon fiber (2 ~ 4mm) 5 parts by weight (hereinafter referred to as "parts")

[0047] Aramid 1414 fiber (5 ~ 6mm) 55 parts

[0048] Polyethylene terephthalamide fiber (5 ~ 6mm) 40 parts

[0049] The carbon fibers of the above-mentioned content are decomposed into pulp A by 0.005% weight concentration in a hydraulic disintegrator, and the above-mentioned content of aramid fiber 1414 fibers (containing part of the pulp) and polyethylene terephthalamide fibers are made by 0.008% by weight. The concentration is decomposed in a hydraulic deflaker to make pulp B, and then the slurry A and the slurry B are mixed uniformly in the batching tank to form paper pulp that can be added to the head box of the papermaking wire, and 5 parts of poly Ethylene oxide. The head of the slurry on the net is adjusted by the pulp stabilizing box, and the slurry is evenly distributed on the paper for...

Embodiment 2

[0052] Prepare the present embodiment 2 synthetic fiber paper by following parts by weight:

[0053] Carbon fiber (2 ~ 4mm) 5 parts

[0054] Aramid 1313 fiber (5 ~ 6mm) 55 parts

[0055] Polyethylene terephthalamide fiber (5 ~ 6mm) 40 parts

[0056] In this example, aramid 1313 fiber is used to replace aramid 1414 fiber. The preparation method of synthetic fiber paper is the same as that of Example 1, and the results obtained are shown in Table 4:

[0057] project

Embodiment 3

[0059] Prepare the present embodiment 3 synthetic fiber papers by following parts by weight:

[0060] Carbon fiber (6 ~ 8mm) 25 parts

[0061] Aramid 1414 fiber (5 ~ 6mm) 35 parts

[0062] Polyethylene terephthalamide fiber (5 ~ 6mm) 40 parts

[0063] In Example 3, without changing the amount of 40 parts of polyethylene terephthalamide fiber, the carbon fiber weight is increased to 25 parts, and the aramid 1414 fiber is reduced to 35 parts. The synthetic fiber paper preparation method is First, single-wire forming and coiling are performed to form a single-layer synthetic fiber paper embryo, and then the single-layer synthetic fiber paper embryo is double-layered, and the rest of the steps are carried out according to the same preparation method as in Example 1. The obtained test results are shown in Table 5:

Abstract

This invention belongs to synthetic fiber domain, specially involves one kind carbon fiber and fragrant black silk ribbon textile fiber as the structure textile fiber, auxiliary synthesis tissue paper which makes by the cementation textile fiber. This synthetic fiber has the light quality, soft, high strength, high compared to module, thermostable, bears wearily, the anti- chemistry corrodes, the good electrical conductivity and the thermal conductivity, the low heat expansion coefficient, biota the solubility is good and so on the outstanding characteristic, may widely use in mechanical and electrical, aviation, astronautics contour area of technology; This invention has also provided this synthesis tissue paper aqueous preparation method

Description

technical field [0001] The invention belongs to the field of synthetic fiber paper, in particular to a synthetic fiber paper made of carbon fiber and aramid fiber as structural fibers and supplemented with bonding fibers. [0002] The invention also relates to a wet method for preparing the synthetic fiber paper. Background technique [0003] In recent years, synthetic fiber paper has attracted widespread attention at home and abroad because of its advantages such as higher strength, dimensional stability, less aging, and chemical resistance than ordinary plant fiber paper. Among them, aramid fiber paper and carbon fiber paper are two important synthetic fiber papers. The Chinese patent application number 99114635.2 discloses a synthetic fiber paper made of polyaramid synthetic fiber, which has certain advantages such as high temperature resistance, high strength, and low deformation, but its disadvantages are: because of its good The insulation performance of paper is non...
