Description
Technical field
The present invention relates to a kind of low temperature cured solvent-free corrosion-resistant epoxy paint and preparation method, it is anticorrosion to be used under the low temperature environment the inside and outside wall of pipeline.
Background technology
The inside and outside wall heavy duty system of existing pipeline is main with epoxypaint mainly, but epoxypaint curing is very big to dependence on temperature, and general curing below 10 ℃ slowly stops below 5 ℃, and completely solidified takes 7 days ability and accomplishes in the time of 23 ℃; And under this cryogenic construction environment, the solvent in the solvent type epoxypaint can't volatilize and limit the further low temperature application performance of this system.For can be at low temperatures also can application of epoxy coating, using more is POLYMETHYLENE POLYPHENYLISOCYANATE and polythiol.
Summary of the invention
In order further to strengthen the anticorrosion ability of the inside and outside wall of pipeline; The invention provides a kind of solvent-free temperature curing epoxy low protective system and preparation method thereof; Used heat-resisting and the better bisphenol A modified epoxy resin of chemical-resistant; Even in the winter time under 4 ℃ of left and right sides low temperature, said bisphenol A modified epoxypaint can fast setting, does not influence production and construction; And, do not add any solvent in the protective system of the present invention, reduced the thinner consumption.The technical scheme that the present invention adopts is following:
A kind of low temperature cured solvent-free corrosion-resistant epoxy paint comprises that weight ratio is the component A and the B component of 100:12.90～24.12, and wherein, said component A comprises following components in weight percentage: bisphenol A modified epoxy resin 26.75～50.0%; Auxiliary agent 6.71～18%; Inorganic color stuffing 43.29～55.75%;
Said auxiliary agent comprises acrylonitrile butadiene rubber modified epoxy resin, benzyl glycidyl ether reactive thinner, modified polyacrylate dispersion agent, fluorine-carbon modified polyacrylate flow agent, gathers methyl alkyl siloxane skimmer, ester class coupling agent, aerosil; Said inorganic color stuffing comprises carbon black, zn phosphate, aluminium triphosphate, mica powder, white titanium pigment, talcum powder, titanium-iron powder; Said B component is a modified fatty amine.
Further, said inorganic color stuffing comprises and accounts for said component A components in weight percentage as follows:
Carbon black 0.1～0.5%;
Zn phosphate 7.0～9.0%;
Aluminium triphosphate 5.0～7.0%;
Mica powder 8.0～10.0%;
White titanium pigment 7.0～9.75%;
Talcum powder 13.19～15.5%;
Titanium-iron powder 3.0～4.0%.
Further, said auxiliary agent comprises and accounts for said component A components in weight percentage as follows:
Acrylonitrile butadiene rubber modified epoxy resin 5.0～10.0%;
Benzyl glycidyl ether reactive thinner 0.0～0.5%;
Modified polyacrylate dispersion agent 1.0～3.0%;
Fluorine-carbon modified polyacrylate flow agent 0.5～2.0%;
Gather methyl alkyl siloxane skimmer 0.01～1.0%;
Ester class coupling agent 0.1～1.0%;
Aerosil 0.1～0.5%.
The preparation method of said low temperature cured solvent-free corrosion-resistant epoxy paint comprises the steps:
In bisphenol A modified epoxy resin, add acrylonitrile butadiene rubber modified epoxy resin, be stirred to then evenly, add various auxiliary agents and color stuffing successively by said ratio again, normal temperature is ground to granularity≤60 μ m after stirring down, filters and packages then, promptly gets the A component; The A component promptly gets this product with the B component according to certain mixed again.
Low temperature cured solvent-free corrosion-resistant epoxy paint of the present invention and preparation method, A component add that by bisphenol A modified epoxy resin acidproof, the alkaline-resisting inorganic color stuffing of a spot of auxiliary agent and some amount is formulated, and the B component is made up of modified fatty amine.In the preparation process,, used the lower bisphenol A modified epoxy resin of ratio of viscosities in order to reduce the viscosity of A component; In order to accelerate low-temperature curing speed, adopted not with reactive thinner or added the reactive thinner of minute quantity and the method for solubilizing agent not; Too fast in order to prevent because of film curing, and the phenomenon that causes paint film to become fragile has been added acrylonitrile butadiene rubber modified epoxy toughening agent; Add the antirust color stuffing of acid and alkali-resistance, improved the non-corrosibility of coating.The modified polyacrylate solution that uses can improve the moisture dispersibility of color stuffings such as carbon black, white titanium pigment.Fluorine-carbon modified polyacrylate solution is improved the leveling characteristics and the gloss of coating, produces the long wave effect, and prevents the shrinkage cavity of system.Gather methyl alkyl siloxane solution and reduce the surface tension of coating system, improve liquidity with leveling characteristics and help to eliminate the bubble in the coating, and avoid the formation of Bei Nade whirlpool.The titanate coupling agent that uses is a kind of novel interfacial material of releasing in recent years, in coating, can pass through face, filling surface coupling combination, and and the polymer base-material carry out crosslinkedly, combine two kinds of materials of different nature, serve as a connection.From bonding strength, the degree of scatter of raising color stuffing base-material, and the amplitude that reduces interfacial free energy, coupling agent surpasses tensio-active agent greatly.Tensio-active agent has transport phenomena, influences gloss, outward appearance and sticking power; And coupling agent can change the interfacial state between inorganics and the organism effectively, and is effective especially to improving dispersiveness and the anti-settling property of color stuffing in organic system, can not only shorten milling time; Improve the dispersion efficiency of color stuffing, the system viscosity of making declines to a great extent, and increases mobile; Improvement is to the wettability of base material; Improve the mechanical property and the chemical property of paint film, color and luster and to the adherence of various base materials, so also be the adhesion promoter of base material.
Solvent-free temperature curing epoxy low protective system of the present invention has the following advantages:
1, low-temperature curing film forming, even but fast setting still under 4 ℃ of left and right sides low temperature in the winter time, construction technology is simple and convenient, does not receive changes of seasons and limit production is constructed; Need not to use special low temperature curing agent, need not specific installation, save energy reduces cost; 2, excellent physical and mechanical properties, sticking power, snappiness are good, excellent in cushion effect, thermotolerance, water tolerance, chemicals-resistant stability.
