Problems solved by technology

A material that can simultaneously have high strength, low deformation, high temperature resistance, chemical corrosion resistance, flame retardancy, no fatigue response and excellent insulation performance - aramid fiber paper, a high-performance synthetic material, came into being. Among them, Chinese patent ZL99114635.2 Disclosed is a synthetic fiber paper made of polyaramid synthetic fiber and polyester fiber, which has certain advantages such as high temperature resistance, high strength, and low deformation, but due to slightly higher weight loss and insufficient flame retardancy Insufficient, can not meet some special purposes; In addition, Chinese patent application 200410037774.8 discloses a manufacturing technology of carbon fiber aramid fiber synthetic paper, in some special properties, if it does not have insulation performance, the radiation resistance is not enough satisfactory

Embodiment 1

[0032] Prepare the present embodiment 1 synthetic fiber paper in the following proportions:

[0033] Polyphenylene sulfide fiber (2-4mm) 80 parts by weight (hereinafter referred to as "parts")

[0034] Aramid 1414 fiber (5 ~ 6mm) 20 parts

[0035]The polyphenylene sulfide fiber with the above content is decomposed into pulp A by 1% weight concentration in a hydraulic debonding machine, and the aramid fiber 1414 fiber (including part of the pulp) with the above content is decomposed in a hydro debonding machine according to 1% weight concentration to make pulp A. Pulp B is formed, and then slurry A and slurry B are mixed evenly in the batching tank to form papermaking pulp that can be added to the headbox of the papermaking wire, and 5 parts of polyethylene oxide are added to the pulp stabilization box. The head of the slurry on the net is adjusted by the stabilizer box, and the slurry is evenly distributed on the paper forming wire in the headbox, and the excess slurry is ove...

Embodiment 2

[0038] Prepare the present embodiment 2 synthetic fiber paper by following parts by weight:

[0039] Polyphenylene sulfide fiber (2 ~ 4mm) 80 parts

[0040] Aramid 1313 fiber (5 ~ 6mm) 20 parts

[0041] In this embodiment, aramid fiber 1313 fiber (containing 0-20% precipitated fiber) is used to replace aramid fiber 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 2:

[0042] project

Embodiment 3

[0044] Prepare the present embodiment 3 synthetic fiber papers by following parts by weight:

[0045] Polyphenylene sulfide fiber (6 ~ 8mm) 55 parts

[0046] Polyphenylene sulfide particles (200 mesh) 25 parts

[0047] Aramid 1414 fiber (5 ~ 6mm) 20 parts

[0048] In Example 3, without changing the amount of 20 parts of aramid fiber 1414, the weight of polyphenylene sulfide fiber was reduced to 55 parts, and 25 parts of 200-mesh polyphenylene sulfide particles were added. The synthetic fiber paper was prepared according to the method of Example 1. The same preparation method is carried out, and the test results obtained are shown in Table 3:
