Abstract
The invention discloses emulsified asphalt for a protective coating, which comprises the following raw materials in parts by weight: 30-55 parts of asphalt, 10-20 parts of octadecyl dimethyl benzyl ammonium chloride, 5-10 parts of fatty acid methyl ester polyoxyethylene ether, 5-12 parts of sodium carboxymethyl cellulose, 8-15 parts of isobutyl acrylate and 20-60 parts of water. The emulsified asphalt is used for the protective coating of metal, can form a compact coating, increases the shielding property of the emulsified asphalt coating on a metal matrix, and further improves the corrosion resistance of the emulsified asphalt coating.
Description
Technical field
The present invention relates to a kind of emulsified bitumen, be specifically related to a kind of emulsified bitumen that is used for protective coating.
Background technology
After so-called emulsified bitumen melts pitch heat exactly, after high speed machine is sheared, be scattered in the aqueous solution that contains emulsifying agent the bitumen emulsion of the oil-in-water-type of formation with tiny graininess.The pitch of this dispersion system is disperse phase, and water is external phase, has good flowability under the normal temperature.Petroleum pitch has good agglutinating value(of coal), resistance to deterioration and water-tight corrosion-proof ability, is widely used as for a long time building the road and sealing material.Because the loss that metallic corrosion causes is very serious, and particularly the protection against corrosion of iron and steel has caused domestic and international concern day by day, be one of main method that prevents steel corrosion at present and apply protective system.For a long time, the steel surface protective system adopts the solvent-borne type protective system mostly.The disadvantage of this coating is that contaminate environment, inflammable, harmful, solvent cost an arm and a leg.
Summary of the invention
The present invention for solution use at present environmental pollution that the steel surface protective system brings, inflammable, problem such as cost an arm and a leg; A kind of cheap and easy to get, emulsified bitumen that is used for protective coating that environmental pollution is few has been proposed; It is by pitch; Stearyl dimethyl benzyl ammonium chloride, fatty acid methyl ester Soxylat A 25-7 and Xylo-Mucine, the composite by a certain percentage compound emulsified bitumen that forms of NSC 20949 and water, its weight consists of:
30～55 parts of pitches
10～20 parts of stearyl dimethyl benzyl ammonium chlorides
5～10 parts of fatty acid methyl ester Soxylat A 25-7s
5～12 parts of Xylo-Mucines
8～15 parts of NSC 20949s
Water 20-60 part
For making the emulsified bitumen that is used for protective coating of the present invention reach best result of use, raw material used among the present invention carries out proportioning by following weight composition:
50 parts of pitches
16 parts of stearyl dimethyl benzyl ammonium chlorides
7 parts of fatty acid methyl ester Soxylat A 25-7s
7 parts of Xylo-Mucines
10 parts of NSC 20949s
30 parts in water
Wherein said pitch is straight-run pitch, half oxidized bitumen or oxidized bitumen, and its penetration degree is 50～200 (1/10mm), is preferably 80～150 (1/10mm).
The bituminous emulsion process is that pitch is distributed in the water with tiny particulate state equably, forms stable emulsion, and this process is the important step that influences the emulsified bitumen quality.When pitch with after emulsifying agent contacts, the oleophilicity group in the emulsifying agent embeds in the water molecules, gets the high speed shear effect through colloidal mill simultaneously, in the aqueous solution, becomes oil-in-water milk sap with the fine particles distributions.
Adopt stearyl dimethyl benzyl ammonium chloride as basic emulsifying agent among the present invention; As co-emulsifier, dwindled relative density difference and the difference of viscosity between profit with the fatty acid methyl ester Soxylat A 25-7, two mutually between emulsifying agent when aligning; Strengthen the electromotive force of pitch particulate. form electrostatic double layer; Increase the mutual repulsive force between the particle, hindered bituminous and assemble tendency, formed comparatively stable emulsified bitumen.Add the polymer Xylo-Mucine in the bitumen emulsion of the present invention as stablizer, can improve aqueous viscosity, can on dispersed microparticles, form interfacial film, be difficult for coalescence when its particulate is collided each other, reduce the settling velocity of pitch particulate.The present invention can form fine and close filming after having added the sanitas NSC 20949, has increased the shielding of emulsified bitumen coating to metallic matrix, makes the corrosion resisting property of emulsified bitumen coating further improve.
The Preparation of Emulsification Asphalt method that is used for protective coating of the present invention is: at first pitch is heated to 140-150 ℃; Again desired raw material stearyl dimethyl benzyl ammonium chloride, fatty acid methyl ester Soxylat A 25-7, Xylo-Mucine, NSC 20949 are mixed with the aqueous solution in 50-60 ℃ by weight; Then pitch and this aqueous solution are together passed through emulsifying device, can make the emulsified asphalt product that is used for protective coating of the present invention.Emulsified bitumen of the present invention can be used for underground outside surface of burying metallic conduit and apply the anticorrosion coating of bridge steelframe.
The invention has the beneficial effects as follows:
(1) the long-time storage of emulsified bitumen good stability that is used for protective coating of the present invention also is difficult for condensing into piece.
(2) emulsified bitumen of the present invention is used for Metal Protection coating, can form fine and close filming, and has increased the shielding of emulsified bitumen coating to metallic matrix, makes the corrosion resisting property of emulsified bitumen coating further improve.
(3) making method of the present invention is easy, raw materials usedly all is easy to get, and is emulsified solvent with water, and environmental pollution is little.
