Abstract
The invention discloses an ethylene propylene diene monomer regenerated rubber modified asphalt anti-rust paint and a preparation method thereof. The anti-rust paint is mainly composed of an ethylene propylene diene monomer regenerated unvulcanized rubber modified petroleum asphalt solution, an aliphatic hydrocarbon solvent, organobentonite, a dispersing agent, a tinting pigment, barite powder, fluorapatite powder, triethyl aluminum and a rare-earth composite drier. The rare-earth composite drier and triethyl aluminum are added to absorb oxygen atoms in air, thereby implementing dual drying of solvent volatilization and oxidation crosslinking. The anti-rust paint prepared by the technique can form a tough coating after dry as a bone, and the coating has the characteristics of favorable elasticity, favorable flexibility, favorable wear resistance, favorable impact resistance and the like. The product can be used for traditional rust prevention for common metals, and can also be used for rust prevention and corrosion resistance of petroleum pipelines in a harsh environment.
Description
Technical field
The present invention relates to a kind of coating, particularly a kind of regenerated rubber modified oil pitch rust-inhibiting paint.
Background technology
Pitch is with a long history as coating, China in early days with the byproduct tar of coking plant, producer gas plant brush inland river wooden boat, timber, bamboo fence etc. are carried with anticorrosion in river.Due to the development of synthetic resins, new coating continues to bring out in recent years.But because bituminous varnish has special performance, add the advantages such as aboundresources, cheap, easy construction, still occupy so far certain status.
The bituminous varnish of manufacturing coating is mainly rock asphalt, petroleum pitch and coal tar pitch three classes.Rock asphalt glossiness is high, and matter is hard, and energy and Vegetable oil lipoprotein well merge, and this veriety is best, and still, price is higher.Tar-bitumen is the byproduct that coke-oven plant, producer gas plant obtain in the time manufacturing coke gas, and coal tar pitch is because containing a large amount of phenol and benzene, and toxicity is very large, and taste is very smelly, very large to workmen's murder by poisoning.The toxicity of petroleum pitch is little, there is no smell, people is safe from harm substantially, but antiseptic property does not have coal tar pitch good.
The fusing point that pitch is not fixed, low temperature is brittle cracking, and high temperature trickling, so pitch can not do separately coating, must pass through modification.
Traditional bituminous varnish has four kinds, and the one, dry vegetable oil modifying asphalt paint; The 2nd, rosin derivative modifying asphalt paint; The 3rd, synthetic modifying asphalt paint, synthetic resins comprises epoxy resin, polystyrene resin, resol, aminoresin, isocyanate resin; The 4th, the bituminous varnish that has unfilled bitumen to make.
The bituminous varnish of dry vegetable oil modification, typical dry vegetable oil is as oleum lini, perilla oil, cannabis oil and tung oil, and the dry vegetable oil of this class is because hold at high price, and cost compare is high, so this class bituminous varnish has seldom been seen in the market.
At home on market, epoxy coal tar pitch paint, because it has good water-fast, alkaline-resisting, chemical proofing, has very strong adhesion property to metal, still very in fashion at present.But this product is because adopting thickness coal-tar pitch, it is containing benzene, containing phenol, and toxicity is very large, and pungency is also very large, very large to workmen's Health hazard.
At present, the rust-inhibiting paint kind using on domestic market has alcohol acid antirust paint, phenolic antirust paint, epoxy anti-rust paint, inorganic zinc silicate rust-inhibiting paint, highly-chlorinated polyethylene rust-inhibiting paint, chlorinated polyvinyl chloride rust-inhibiting paint, transformant conversion and prevention paint of rust, epoxy coal tar pitch rust-inhibiting paint.
Summary of the invention
The object of the invention is the shortcoming in order to overcome above-mentioned background technology, provide one to utilize ethylene-propylene diene reclaimed rubber modifying asphalt filmogen, development one sprays dry, has remarkable rustless property, to the low murder by poisoning of people, rust-inhibiting paint with low cost and preparation method thereof.
