Abstract
Water-based anticorrosive paint for metal is green, energy-saving and high-technology anticorrosive paint resistant to high temperature, water, damp, acid and bases, oil and oxidation, and belongs to air-dried high-temperature resisting anticorrosive paint. A coating is compact and hard at high temperature, free of bubbling, cracks and peeling off, excellent performance is achieved, the needs of national major projects are met, and the paint is suitable for the needs of development of petrochemical engineering, metallurgy, fertilizer and other industries. The advantages of being resistant to corrosion, oxidation and damp and heat, high in strength, low in curing temperature and cost and the like are achieved, and the paint is the unique choice of metal equipment. The paint is widely applied to corrosion prevention of plants, equipment, various steel storage tanks and large steel structures, and has wide market prospects.
Description
Technical field
Waterborne metal anti-corrosive paint is that a kind of high temperature resistance is anti-oxidation, organic solvent-resistant, acid-alkali-corrosive-resisting, waterproof and dampproof energy-saving high-tech metal protective system.
Background technology
Metallic substance can occupy critical role at Material Field with its excellent mechanical property and processing performance, but metallic corrosion also causes massive losses to human society, and therefore developing that efficient protective system protects it is the method the most simply commonly used.The facility such as the storage equipment manufactured by metallic substance, petrochemical equipment, storage roof, Large Steel building slab, on the one hand can because being damaged by corrosion by the chemistry of surrounding medium or electrochemical action for a long time, hidden danger can be brought on the other hand because of heat absorption intensification in summer or other hot conditionss, traditional spray water and reinforce the method for cystose, the inconvenience but also the waste of water resources can be caused of not only having constructed.Along with global evolution is to the great attention of resource, environment, energy-saving and environment-friendly paint especially Compound waterborne coating is developed rapidly, and they play important effect to the protection against corrosion of metal construction.
Summary of the invention
The high temperature resistant inorganic modification chelating grafting film-forming soln that waterborne metal anti-corrosive paint adopts will Sheng Weihua Chemical Co., Ltd. special, based on inorganic silicon-Si-O-Si-strong, grafting hydroxyl is the anticorrosion film-forming thing that the grafting of side chain chelating becomes, and solution heatproof is high, can reach 1000 DEG C.Inorganic modified solution film forming thing is finer and close, strong adhesion, under high temperature thermochemistry and thermophysics more stable.Anti-corrosion paint is through the composition such as nanoscale graphite scale, nano metal intermediate oxide, ultra-fine ultrafine powder of high dispersing activation.Prevent gas, liquid comes into contact under being applicable to high temperature, enter applicator matrix, protection basic material is not corroded oxidation, can resistance to heavy corrosion, and wear-resisting anti-aging, good heat conductivity, ductility is strong.Not containing VOC, pollution-free, nontoxic, non-volatile friendly environmental protection coating material.
Under the high temperature conditions, can there is thermal destruction and carboniogenesis in general coating, cause breakdown of coating, do not have provide protection.And metal use protective system has under the high temperature conditions, coating does not chap, non-foaming, the feature of not peeling off, still can keep certain physical and mechanical properties, makes metal objects from thermal chemical damage, thermooxidizing, extends its work-ing life.And can large-area construction under film normal temperature, cost is low, to solve after the large-scale steel equipment application of high temperature barbecue the limitation such as inconvenience transport, installation.This coating energy normal temperature self-drying or comparatively low temperature (100 ~ 150 DEG C) are dried, the new Heat Resistant Coating used within the scope of 200 ~ 1000 DEG C.
As can be seen here, waterborne metal anti-corrosive paint have high temperature resistant, shock-resistant, anti-oxidant, protection against corrosion, waterproof and dampproof, from dry fast, strong adhesion, coating process are good, the advantages such as easy construction, can use within the scope of 200 ~ 1000 DEG C, are the ideal materials of high temperature protection.With the antiseptic property of its excellence, long-term weathering resistance, good thermal conductivity, water tolerance and resistance to salt water, resistance to various oil product long period of soaking, to various organic solvent, comprise ketone, ester, ether, alcohol, hydro carbons strong solvent have extremely strong resistivity, can be used for the long-effective corrosion of the various steel construction pieces being exposed to marine atmosphere, high temperature and each environment.Comprise the steel and iron member of boats and ships, freight container, harbour various kinds of equipment, heavy construction, be particularly suitable for storage tank, oil tanker, solvent cabin inwall, heat exchanger inwall and oil pipeline, chemical pipeline etc., there is no the volatilization of solvent in construction and coating curing process, workmen and surrounding environment are not worked the mischief.
Metal water-based anticorrosive paint performance is for shown in following table:
Accompanying drawing explanation
Fig. 1 is the proportioning raw materials of waterborne metal anti-corrosive paint.
(1) water glass (2) silicon sol (3) silica flour (4) deionized water (5) 5% hydrochloric acid (6) aluminum oxide powder (7) yttrium oxide (8) silicon carbide (9) talcum powder (10) platinum (11) film coalescence aid (12) Sodium hexametaphosphate 99 (13) antifoam additives (14) waterproof agent (15) Natvosol (16) Union carbide A-162 (17) PH conditioning agent (18) dispersion agent.
Embodiment
1, water glass, silicon sol, silica flour, deionized water are put into elevated temperature vessel, first stir, sealing, solution is elevated to 500 DEG C of high temperature chelatings and continues 120 minutes.Stir again after lowering the temperature, add PH regulate auxiliary agent, stir after, add 5% hydrochloric acid, Sodium hexametaphosphate 99 stir, stir after place slaking in 24 hours.
2, second day, after 24 hours, solution stirs again, adds yttrium oxide, silicon carbide, aluminum oxide powder, talcum powder stirring successively, stir after 30 minutes, add waterproof agent, film coalescence aid, antifoam additives, Natvosol, Union carbide A-162, dispersing auxiliary.
3, be stirred coating and platinum is put in elevated temperature vessel, container sealing is heated to 70 DEG C, continue to cool after 30 minutes.
4, promote that coating is cross-linked further like this, coating compactness after guarantee coating application, high water-repellancy and protective system, sticking power is high, has good malleability, resistance to acids and bases, brushes and effectively ensure that metal does not corrode under acid and alkali corrosion on metal.
Claims (4)
1. waterborne metal anti-corrosive paint adopts special inorganic solution to be film-forming soln, inserts multiple high dispersing activation body and unique water-based anticorrosive paint of making, integrate the preventing metal corrosion coating of environment friendly, safety in utilization and economic performance type.
2. this coating is for the metal under water and especially harsh corrosive environment of equipment, there is waterproof and dampproof, acid-fast alkali-proof, grease proofing, anti-oxidation feature, coating structure is fine and close, shielding isolation action is strong, the contact of effective prevention corrosive medium and ground, extend corrosive medium to matrix permeability, reach the effect of inhibition.
