Abstract
The invention relates to an asbestos-free fiber compressed plate and a preparing method thereof. The compressed plate and the preparing method are characterized in that the compressed plate comprises 5-10% by weight of aramid fibers, 5-10% by weight of phenolic fibers, 45-55% by weight of acrylic fiber pulp or acrylic fibers, 3.0% by weight of paper pulp, 7.0% by weight of natural rubber, 5.6% by weight of nitrile butadiene rubber or chloroprene rubber or styrene-butadiene rubber or ethylene propylene terpolymer, 0.3% by weight of sulfur, 0.3% by weight of a rubber accelerator M, 0.3% by weight of an antiager D, 0.7% by weight of zinc oxide, 2.0% by weight of polyurethane varnish, 1.4% by weight of phthalocyanine blue and 14.2% by weight of barium sulfate. Compared with the prior art, the compressed plate and the method are advantageous in that the compressed plate is absolutely free of asbestos and free of sepiolite, and mainly comprises the acrylic fibers, the prepared compressed plate is sufficient in strength and very low in leakage rate, tensile strength and wear resistance are greatly enhanced by adding the aramid fibers and the phenolic fibers.
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:
Aramid fiber: 5 ~ 10%
Phenolic fibre: 5 ~ 10%
Acrylic fibers pulp or acrylic fiber: 45 ~ 55%
Paper pulp: 3.0%
Natural rubber: 7.0%
Nitrile rubber or neoprene latex or butadiene-styrene rubber or ethylene-propylene diene copolymer: 5.6%
Sulfur: 0.3%
Captax: 0.3%
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.
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 aramid fiber, phenolic fibre, acrylic fiber or acrylic fibers slurry, paper pulp, natural rubber, paracril or neoprene latex or butadiene-styrene rubber or ethylene-propylene diene copolymer, Sulfur, rubber accelerator M, antioxidant D, zinc oxide, Polyurethane varnish, titanium blue and these 13 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 acrylic fiber, obtained sheet material has enough intensity, simultaneously leakage rate is very low, adding of aramid fiber and phenolic fibre, considerably increases again tensile strength and wear resistance.
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:
Aramid fiber: 5 ~ 10%
Phenolic fibre: 5 ~ 10%
Acrylic fibers pulp or acrylic fiber: 45 ~ 55%
Paper pulp: 3.0%
Natural rubber: 7.0%
Nitrile rubber or neoprene latex or butadiene-styrene rubber or ethylene-propylene diene copolymer: 5.6%
Sulfur: 0.3%
Captax: 0.3%
Antioxidant D: 0.3%
Zinc oxide: 0.7%
Polyurethane varnish: 2.0%
Titanium is blue or green blue: 1.4%
Barium sulfate: 14.2%.
This formula 100% is without asbestos, and without sepiolite, based on acrylic fiber, obtained sheet material has enough intensity.For different use media, wherein paracril can use neoprene latex instead, the stupid glue of fourth, and ethylene-propylene diene copolymer etc. substitute, and as needed other color, can use other dyestuff instead.
In the present embodiment, natural rubber adopts 1# cigarette electricity glue, and paracril adopts 26# paracril.
The above-mentioned preparation method without fibrous magnesium silicate compressed panel comprises the steps:
Step 1, blue or green to aramid fiber, phenolic fibre, acrylic fiber or acrylic fibers slurry, paper pulp, natural rubber, paracril or neoprene latex or butadiene-styrene rubber or ethylene-propylene diene copolymer, Sulfur, rubber accelerator M, antioxidant D, zinc oxide, Polyurethane varnish, titanium blue and these 13 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.
