In all rubber kinds, what be typically used as at home corrosion protective lining occasion has two kinds of natural rubber and isoprene-isobutylene rubbers, but for Seawater, require it to there is good resistance to erosion abradability simultaneously, acid resistance, weathering resistance, high-adhesive-strength with steel, the over-all propertieies such as slow fouling performance, all Shortcomings parts of above-mentioned two kinds of rubber, the external general chloroprene rubber that adopts is as backing layer, at home, the neoprene neoprene of some mold pressings also has utilization, but as corrosion protective lining rubber plate, due to external maintaining secrecy to formula and complete processing, main dependence on import.
About the design of chloroprene rubber plate, technology existing relevant in prior art is open, as China Patent No.: CN 201110115153.7, denomination of invention is: chloroprene rubber composition, the component of the disclosed chloroprene rubber plate of this application scheme is: chloroprene rubber, styrene-butadiene rubber(SBR), Sulfur, zinc oxide, anti-aging agent RD, hard (china) clay, semi-reinforcing furnace black, high reactivity carbon black, accelerant CZ, promotor TS, promotor TRA, n-butyl sebacate, diaryl-p-phenylenediamine, γ-sulfydryl propyl trimethoxy silicane, phenyl-β. naphthylamines and diphenyl-para-phenylene diamine's mixture, this application case has improved the winter hardiness of rubber by adding auxiliary agent, but there is no advantage aspect acid and alkali-resistance brine corrosion, be not suitable for sea water conveying pipelines.
In addition, Chinese patent CN 201310590183.2, denomination of invention is: a kind of chloroprene rubber, this application scheme has improved the aging resistance of resistance to dynamic ozone of rubber, is not suitable for equally sea water conveying pipelines.
Therefore, develop a kind of corrosion protective lining that can be suitable for sea water conveying pipelines chloroprene rubber plate, marketable value is very large.
Summary of the invention
1, the technical problem that invention will solve
The object of this invention is to provide a kind of corrosion protective lining chloroprene rubber plate that there is high abrasion, water-fast hammering blow, acid and alkali-resistance brine corrosion and can be suitable for sea water conveying pipelines.
2, technical scheme
For achieving the above object, technical scheme provided by the invention is:
Corrosion protective lining chloroprene rubber plate for sea water conveying pipelines, is made up of the component of following parts by weight:
100 parts of chloroprene rubbers, stearic acid 1.5-3 part, resin 3-6 part, processing aid 1-2 part, semi-reinforcing hydrocarbon black 15-30 part, thermals 30-45 part, talcum powder 20-40 part, subtracts third fractional oil 8-15 part, plumbous oxide 15-25 part, altax 0.5-2 part.
Further, this chloroprene rubber plate is made up of the component of following parts by weight:
100 parts of chloroprene rubbers, 2 parts of stearic acid, 5 parts of resins, 2 parts of processing aids, 20 parts of semi-reinforcing hydrocarbon blacks, 40 parts of thermalss, 30 parts of talcum powder, subtract 10 parts of third fractional oils, 20 parts, plumbous oxide, 1 part of altax.
3, beneficial effect
Adopt technical scheme of the present invention, compared with existing known technology, there is following unusual effect:
(1) formulating of recipe of chloroprene rubber plate for corrosion protective lining of the present invention, fully take into account processing characteristics, adhesiveproperties and the sulfuration process of rubber, select on this basis suitable rubber substrate, consider again the property of sea water resistance medium, select metal oxide+stearic acid as vulcanization system for guarantee medium-resistance promotor, for taking into account reinforcement and insulativity, select half reinforcement+thermals as reinforcement system, softening system is selected and is subtracted third fractional oil
(2) high-performances such as the present invention has high abrasion, water-fast hammering blow, acid and alkali-resistance brine corrosion, high temperature resistance, slow fouling, bonding strength is high, running resistance is little, fill up domestic blank, its property indices and external product, can be extensively at power generation with sea water, sea water desaltination industry applications in peer-level.
(3) isoprene-isobutylene rubber plate chemical property of the present invention is highly stable, and the erosion of the most corrosive mediums of ability and organic solvent is more corrosion-resistant than plastics such as polyethylene, polypropylene, nylon, ABS.Except strong oxidizing property acid solution, the various corrosive mediums of ability (acid, alkali, salt) and organic medium (except naphthalene solvent) in certain temperature and concentration range, in 80 kinds of organic solvents of 20 DEG C and 80 DEG C, soak stagnant 30 days, appearance is without any abnormal phenomena, and other physicals does not also almost change.
