Use purified lacquer-phenol solution, after modification,, added the number of chemical auxiliary agent,, be prepared into anticorrosive coating as catalyzer, linking agent, auxiliary and modified filler etc. according to a certain amount of proportioning.This coating has anti-strong acid, highly basic and high temperature and anti-organic solvent, resists the ability of various salts, thalassochemistry dielectric corrosion, and easy construction, human body is not had good characteristics such as supersensitivity.
Description
The present invention relates to raw lacquer is the technology that main raw material prepares corrosion resistant coating of phenol-titanium varnish chelated with high polymer.
Raw lacquer is the special product of China, aboundresources, and its output ranks first in the world.Because the raw lacquer paint film has advantages such as durable, hard, bright, corrosion-resistant, heat-resisting, wear-resisting, thereby is applied to many aspects such as industrial art product, furniture, textile equipment, building in large quantities.But owing to the character of raw lacquer own, remain in some shortcomings, big as raw lacquer viscosity, be difficult to spraying; Drying varniss needs conditions such as specific temperature, humidity, and rate of drying is slow, long construction period; Human body there is serious supersensitivity; Poor adhesive force to metal; Alkali resistance is more weak etc., has limited its range of application widely.Especially some are in for a long time and are very restricted aspect the protection against corrosion of the production unit of working in the severe environment at chemical industry equipment, maritime facilities etc.At present, be applied to that the anticorrosive coating of equipment and some maritime facilitieies is essentially chemosynthesis paint in each chemical plant.As: chlorosulfonated polythylene coatings, G-615 anticorrosive coating, PF-01 type anticorrosive coating, bituminous epoxy enamel paint, H52-3 epoxy anticorrosion enamel paint of all kinds etc., because these chemistry paint acid-and base-resisting, over-all propertieies such as chemically-resistant solvent corrosion are poor, and wear resistance, hardness, thermotolerance are also not as raw lacquer.A few thermotolerance is the chemistry lacquer well, and as organic silicon coating, turnout is few, cost an arm and a leg, and acidproof or alkaline-resisting or organic solvent-resistant corrosive ability is relatively poor.Owing to there is not the anticorrosive coating of excellent combination property, cause many chemical industry equipments, maritime facilities heavy corrosion, cause the production unit corrosion of a large amount of costlinesses to damage, even cause some serious accidents.
About the research of phenol-titanium varnish chelated with high polymer as anticorrosive coating, we have consulted fascicles such as " organic chemistry ", " polymer chemistry " in " U.S. chemical abstract " (1907～1988 years), " Britain's World Patent Index " (1974～1988) and " patent documentation circular ", " coating dyestuff ", result for retrieval shows: mainly stress raw lacquer analysis of components, drying mechanism, come modified raw lacquer with aldehydes, vinyl, epoxies or dryness oils, and research such as laccol structure and composition, do not see the research report of relevant phenol-titanium varnish chelated with high polymer.
The purpose of this invention is to provide a kind of is main raw material with raw lacquer, synthesizes anticorrosive coatings such as can being widely used in chemical industry equipment, maritime facilities.This coating has anti-strong acid, highly basic and high temperature, has the ability of good anti-organic solvent, anti-various salts, thalassochemistry dielectric corrosion, and can film on multiple base material, and energy seasoning, easy construction do not have good characteristics such as supersensitivity to human body.
The present invention realizes by following steps:
One, synthetic
1, the purification of laccol: raw lacquer is dissolved in acetone or alcohol, the dimethylbenzene equal solvent, its amount ratio is 1: 1(W/V), remove by filter insoluble substance, filtrate was left standstill more than 30 minutes, with separating funnel or whizzer layering, the benzene that adds equivalent in the upper strata laccol liquid of telling, underpressure distillation obtain pure laccol after removing remaining moisture and solvent.
2, (250 rev/mins) limit adding properties-correcting agent and catalyzer are stirred in the limit in pure laccol, mix.Properties-correcting agent can adopt TiX
4, Ti(OR)
4; Catalyzer can adopt organic titanium salt etc.The consumption of properties-correcting agent accounts for 10～30% of laccol amount, and optimum quantity is 15-18%, and catalyst consumption accounts for 0.05～2.0% of laccol amount, and optimum quantity is 0.5～1%.
3, add linking agent under constantly stirring, linking agent can adopt dicumyl peroxide, polyamines class etc.Add post-heating to 150 ℃ and keep cooling again more than 30 minutes.The consumption of linking agent accounts for 2～10% of laccol amount, and optimum quantity is 5～7%.
4, add auxiliary, auxiliary can adopt polynuclear compound, phenanthrene, naphthalene, Resins, epoxy etc.Add fashionable stirring and be heated to 110 ℃; Time is 10 minutes, promptly makes anticorrosive coating.The consumption of auxiliary accounts for 15～25% of laccol amount, and optimum quantity is 20% or further adds modified filler again, stirs, and at last coating is cooled to below 60 ℃, and filters with 200 eye mesh screens.Modified filler can adopt active silica, graphite, titanyl sulfate, chromium sesquioxide, titanium dioxide, wollastonite, carbon black, sheet mica etc., and its consumption accounts for 0～50% of lacquer liquid measure.
Two, join lacquer: in the coating for preparing, add dimethylbenzene or turps, regulate about the solids content to 40% of lacquer liquid.
Main points of the present invention are: with laccol, properties-correcting agent is main raw material, be aided with other chemical assistant, comprise catalyzer, linking agent, auxiliary and modified filler etc., the consumption of filler is decided on the cost of etch-proof object and preparation lacquer liquid, and the highest 50%(of adding to accounts for the lacquer liquid measure).
Prescription of the present invention is:
Laccol 100 grams
Properties-correcting agent 10～30 grams
Catalyzer 0.05～2.0 gram
Linking agent 2～10 grams
Auxiliary 15～25 grams
Modified filler 0～50 gram
Optimum formula of the present invention is:
Laccol 100 grams
Properties-correcting agent 15～18 grams
Catalyzer 0.5～1 gram
Linking agent 5～7 grams
Auxiliary 20 grams
Modified filler 0～50 gram
The present invention compares with technology in the past, has solved for a long time that raw lacquer is difficult to make high performance anticorrosive coating, and the coating that the present invention is prepared has good conventional physical and mechanical properties and excellent corrosion resistance:
1, the ability that has very strong alkaline-resisting, acid corrosion-resistant.Ability is more than 5 hours, at 80 ℃ 50%NaOH solution and 70%H in 320 ℃ of fused NaOH
2Equal ability is more than 8000 hours in the SO solution.
2, the good anti-organic solvent and the ability of petroleum products are arranged.As 120
#Anti-more than 5 years in the gasoline.
3, good anti-various salts, the ability of various thalassochemistry media are arranged.No matter normal temperature or hot down all can be corrosion-resistant for a long time, be new coating with anticorrosive wide spectrum.
4, can on multiple base material, film, have good sticking power.This application of paints is in multiple chemical industry equipment protection against corrosion, and is respond well, has the resistance toheat higher than raw lacquer, the energy seasoning, and easy construction does not have supersensitivity to human body.
