Abstract
The invention relates to an asbestos-fiber-free compressed panel and a preparation method thereof. The invention is characterized in that the asbestos-fiber-free compressed panel comprises the following components in percentage by weight: 40-50% of graphite powder, 3-5% of carbon fiber, 5-10% of aramid fiber, 5-10 of acrylon fiber or acrylon pulp, 3.0% of paper pulp, 7.0% of natural rubber, 5.6% of nitrile-butadiene rubber or chloroprene rubber or butadiene styrene rubber or ethylene propylene diene copolymer, 0.3% of sulfur, 0.3% of rubber accelerator M, 0.3% of anti-aging agent D, 0.7% of zinc oxide, 2.0% of polyurethane lacquer, 1.4% of phthalo blue and 14.2% of barium sulfate. Compared with the prior art, the asbestos-fiber-free compressed panel provided by the invention is free of asbestos and meerschaum, and is mainly composed of graphite powder and acrylon fiber. The prepared panel has the advantages of sufficient strength, favorable high temperature resistance and very low leakage rate. The added aramid fiber greatly enhances the tensile strength and wear resistance.
Description
Technical field
The present invention relates to a kind of without fibrous magnesium silicate compressed panel and preparation method.
Background technology
Asbestos rubber compressed panel is widely used for making gasket seal, but because asbestos have harm to human body, some developed countries forbid all, some external automobile brands also strictly prohibit the use the pad containing asbestos, so each producer has to set about developing the formula without asbestos compressed panel, domestic method the most conventional replaces asbestos with sepiolite, but sepiolite is general and asbestos are twin ore deposits, be difficult to thoroughly be separated, obtained sheet material is carried out with this formula, if have X-ray to detect, still can find the asbestos of 5 ~ 10%, finally reject by the client of more American-European developed countries, cause very large loss.。
Summary of the invention
Primary technical problem to be solved by this invention provides a kind of without fibrous magnesium silicate compressed panel for above-mentioned prior art.
The further technical problem to be solved of the present invention is to provide a kind of preparation method without fibrous magnesium silicate compressed panel.
The present invention solves the technical scheme that above-mentioned primary technical problem adopts: a kind of without fibrous magnesium silicate compressed panel, it is characterized in that: this comprises the component of following weight proportion without fibrous magnesium silicate compressed panel:

Antioxidant D: 0.3%
Zinc oxide: 0.7%
Polyurethane varnish: 2.0%
Titanium is blue or green blue: 1.4%
Barium sulfate: 14.2%.
Preferably, described natural rubber adopts 1# cigarette electricity glue.
Preferably, described paracril adopts 26# paracril.
Preferably, described Graphite Powder 99 adopts 0# Graphite Powder 99.
The present invention solves the technical scheme that above-mentioned further technical problem adopts: a kind of preparation method without fibrous magnesium silicate compressed panel with above-mentioned formula, is characterized in that: comprise the steps:
Step 1, blue or green to Graphite Powder 99, carbon fiber, aramid fiber, acrylic fiber or acrylic fibers pulp, paper pulp, natural rubber, nitrile rubber or neoprene latex or butadiene-styrene rubber or ethylene-propylene diene copolymer, Sulfur, captax, antioxidant D, zinc oxide, Polyurethane varnish, titanium blue and these 14 kinds of materials of barium sulfate to be prepared according to weight proportion described in claim 1, pour in material pool, fully stir;
Step 2, compound step 1 obtained are poured special making in the Cheng Zhangji of compressed panel into and are made without fibrous magnesium silicate compressed panel.
Compared with prior art, the invention has the advantages that: provided by the invention without in fibrous magnesium silicate compressed panel formula 100% without asbestos, without sepiolite, based on Graphite Powder 99 and acrylic fiber, obtained sheet material has enough intensity, and leakage rate is very low simultaneously, adding of aramid fiber, considerably increase again tensile strength and wear resistance, Graphite Powder 99 makes sheet material have good resistance to elevated temperatures, is applicable to 450 celsius temperatures and uses.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail.
The component comprising following weight proportion without fibrous magnesium silicate compressed panel that the present embodiment provides:
