Description
The present invention relates to a kind of corrosion-resistant composite slab rubber material and manufacture method thereof.
At chemical industry, metallurgical, electric power, in the production process of industries such as light industry, the rubber lining of equipment is etch-proof effective ways commonly used, this method requires the densification of lining rubber material structure, to acid, alkali, salt medium has corrosion resistance preferably, with the equipment matrix good adhesive property is arranged, but for a long time, anticorrosion line with rubber plate is the way that adopts first line with rubber after cure, or adopt individual layer pre-vulcanized butyl rubber lining technology, the rubber-lining method of lining after cure earlier, cure time is long, what use is anti-impact force and the relatively poor hard rubber of resistant and oscillation resistant power, its service life is short, the body sulfuration is dangerous, large chemical equipment, the crossbeam that particularly needs line with rubber, groove, jar inconvenience sulfuration, though and the individual layer pre-vulcanized butyl rubber is a kind of corrosion resistance, temperature tolerance, air-tightness is lining material preferably, but its offset plate and metallic object bond properties are relatively poor, delamination easily, and service life is short, the conduction accident appears when the spark test instrument detects easily, therefore, equipment line with rubber technology is subjected to vulcanizing tank volume and sulfuration process, particularly the high steam heat cure can not make the development of line with rubber equipment also be subjected to certain restriction in the restriction of rubber liner on-site construction.
The invention provides a kind of corrosion resistance, anti-impact force, resistant and oscillation resistant power, resistance to tearing and viscosity all are much higher than the double-deck pre-vulcanized butyl rubber composite slab rubber of lining after cure earlier or individual layer pre-vulcanized butyl rubber, it is characterized in that the butyl rubber that will vulcanizate or chlorobutyl rubber are as corrosion-resistant outer layer glue, adopt natural gum, materials such as cis-butadiene cement sulfuration back is as the internal layer bonded adhesives, two kinds of offset plates are fitted and are pressed into the composite slab rubber material, warehouse-in is deposited, ready access upon use, make this composite slab rubber, decay resistance and adhesive property are preferably arranged, use the lining technology of this composite slab rubber, do not need refrigerating equipment, the energy is saved in easy construction, is convenient to repair, be suitable for adopting in the equipment of seriously corroded under different condition and the container, the equipment that is specially adapted to is big, transportation inconvenience, the large-scale groove of sulfuration difficulty, jar, the anticorrosion line with rubber of crossbeam.
The Butylrubber composite rubber plate of pre-vulcanization and corrosion resistant manufacturing comprise compounding ingredient processing, rubber processing, rubber plasticate, cooperate mixing, add technologies (seeing Figure of description) such as sulphur heat refining, four roller slices, applying, compression molding, compression molding.
