Embodiment 1

[0024] Prepare the present embodiment 1 synthetic fiber paper in the following proportions:

[0025] Basalt fiber (2-4mm) 5 parts by weight (hereinafter referred to as "parts")

[0026] Aramid 1414 fiber (5 ~ 6mm) 45 parts

[0027] Polyphenylene sulfide fiber (5 ~ 6mm) 50 parts

[0028] The basalt fiber of above-mentioned content is decomposed in the hydraulic disintegrating machine by 1% weight concentration, makes paper pulp A, and above-mentioned content aramid fiber 1414 fiber (wherein contains 0~20% pulp) and polyphenylene sulfide fiber by 0.5% by weight The concentration is decomposed in a hydraulic decomposer to make pulp B, and then the slurry A and slurry B are mixed evenly in the batching tank, and 5 parts of anti-flocculant are added to the pulp stabilization box. Adjust the pressure head of the slurry through the headbox, and the slurry is evenly distributed on the paper forming wire (double circle wire) in the headbox, and then the paper sheet is hot-rolled and ...

Embodiment 2

[0031] Prepare the present embodiment 2 synthetic fiber paper by following parts by weight:

[0032] Basalt fiber (2 ~ 4mm) 5 parts

[0033] Aramid 1313 fiber (5 ~ 6mm) 45 parts

[0034] Polyphenylene sulfide fiber (5 ~ 6mm) 50 parts

[0035] In this embodiment, aramid 1313 fiber (containing 0-20% precipitated 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 2:

[0037] project

Embodiment 3

[0039] Prepare the present embodiment 3 synthetic fiber papers by following parts by weight:

[0040] Basalt fiber (6 ~ 8mm) 25 parts

[0041] Aramid 1414 fiber (5 ~ 6mm) 25 parts

[0042] Polyphenylene sulfide fiber (5 ~ 6mm) 50 parts

[0043] In Example 3, without changing the dosage of 50 parts of polyphenylene sulfide fiber, the weight of basalt fiber was increased to 25 parts, the weight of aramid fiber 1414 was reduced to 25 parts, and the remaining steps were carried out according to the same preparation method as in Example 1. The obtained test results are shown in Table 3:

Abstract

The invention belongs to the field of composing fiber paper. It relates to composing non-woven paper, especially relates to a kind of fiber paper made by wet method with basaltic fiber, aramid fiber and polyphenylene sulfide fiber. The composing fiber paper has much strongpoint including well mechanical property, good high-temperature resistance, acid resistance, alkali resistance, strength uvioresistant property, low hygroscopic, better environment bearing property, good insulativity, good high-temperature filterability, radio resistance and good wave-passing property. Therefore, the composing fiber paper is applicable for military engineering and civil fields including aerospace, military engineering, vehicle and ship building and architecture.

Description

technical field [0001] The invention belongs to the field of synthetic fiber paper and relates to a synthetic non-woven paper structure, in particular to a fiber paper made of basalt fiber, aramid fiber and polyphenylene sulfide fiber by wet method. [0002] The present invention also relates to a method for preparing the above-mentioned synthetic fiber paper. Background technique [0003] With the development of material science, the performance requirements of paper are increasing day by day, and synthetic fiber paper has been widely concerned because of its advantages such as higher strength than ordinary plant fiber paper, stable size, not easy to aging, and chemical corrosion resistance. In the prior art, synthetic fiber paper made of non-woven paper structure is known, as disclosed in the Chinese patent of Patent No. ZL99114635.2, a synthetic fiber paper made of polyaramid synthetic fiber as raw material, This patent describes a method for making synthetic paper with ...
