Description
Technical field
The present invention relates to a kind of rubber material, especially it is a kind of it is corrosion-resistant it is fire-retardant prevent old type rubber washer, belong to rubber skill
Art field.
Background technique
It is currently used for usually being needed in the pipe-line system of conveying corrosive media using washer is arrived, due to defeated in pipe-line system
The corrosive media sent, the existing common washer of pipe-line system are rubber washer, although however, rubber washer is with outstanding
High and low temperature resistance keeps good within the temperature range of -70 DEG C -+260 DEG C and is easy the advantages that sealing using elasticity, but
It is its poor corrosion resistance, easy to aging, cause its service life low, use need to be regularly replaced often in pipe-line system, maintenance cost
It is high.
Summary of the invention
The purpose of the present invention is, provide a kind of corrosion-resistant fire-retardant to prevent old type rubber pad in view of the above shortcomings of the prior art
Circle, the material have heat-resisting, oil resistant, resistance to chemical corrosion, can extend the service life of rubber washer.
The purpose of the present invention is what is be achieved through the following technical solutions: it is a kind of it is corrosion-resistant it is fire-retardant prevent old type rubber washer,
It is characterized in, each component including following parts by weight is prepared: 15-20 parts of neoprene, 20-35 parts of butadiene rubber, fourth cyanogen rubber
15-40 parts of glue, 8-12 parts of solution polymerized butadiene styrene rubber, 15-25 parts of ethylene propylene diene rubber, 7-9 parts of benzoxazine resin, kaolin 15-
20 parts, 10-15 parts of carbon black, 3-8 parts of anti-aging agent, 1-2 parts of polyethylene glycol, 1-5 parts of polyethylene wax, 2-5 parts of chlorosulfonated polyethylene, silicon
5-8 parts of alkane coupling agent, 20-30 parts of kaolin, 3-5 parts of conductive black, 1-5 parts of sulphur, 1-5 parts of talcum powder, calcium carbonate 15-25
Part, 10-15 parts of clay, 5-9 parts of magnesia, 2-5 parts of aluminium hydroxide, 2-4 parts of antioxidant.
The content of styrene is 16-18% in the solution polymerized butadiene styrene rubber.
The carbon black is carbon black N550, carbon black N95 mixture.
The antioxidant is antioxidant AT-10.
The anti-aging agent is microwax.
Microwax, white-amorphous amorphous solid wax, based on the branched-chain saturated hydrocarbon of C31-70, containing a small amount of ring-type,
Straight-chain hydrocarbons, odorless, tasteless.Insoluble in ethyl alcohol, it is slightly soluble in hot ethanol, dissolves in benzene, chloroform, ether etc.；Can with various mineral waxs,
Vegetable wax and hot fat oil dissolve each other.Mainly using the residue after petroleum fractionating as raw material, it is made using method for refining.
Chlorosulfonated polyethylene is made by low density polyethylene (LDPE) or high density polyethylene (HDPE) through superchlorination and chlorosulfonation.It is white
Color or yellow elastic body can be dissolved in aromatic hydrocarbon and chlorohydrocarbon insoluble in fat and alcohol, and can only be swollen in ketone and ether cannot
Dissolution, there is excellent ozone resistance, resistance to weathering, chemical corrosion resistance etc., preferable physical mechanical property, resistance to ag(e)ing
Energy, heat-resisting and lower temperature resistance, oil resistivity, flame resistance, wearability and resistance to electrical insulating property.
The present invention is using nitrile rubber, chlorosulfonated polyethylene, ethylene propylene diene rubber and neoprene as major ingredient, wherein ternary second
Third rubber is good with nitrile rubber intersolubility, and the two complements each other, and keeps the performance of nitrile rubber more perfect, has the present invention good
Good heat-resisting, oil resistant, pressure-resistant compression permanent deformation performance, and the addition of chlorosulfonated polyethylene and neoprene, further increase
Weatherability and corrosion resistance of the invention.
The present invention has the advantages that excellent resistance to weathering and corrosion resistance, thus avoid corrosive media directly with
The contact of rubber pad ring layer, good corrosion resistance, non-aging, long service life.
