Description
Technical Field
The invention relates to the field of detergents, and particularly relates to an asphalt cleaning agent and a preparation method thereof.
Background
The asphalt is a black-brown complex mixture composed of hydrocarbons with different molecular weights and nonmetal derivatives thereof, is one of high-viscosity organic liquids, is in a liquid state, has a black surface, and is soluble in carbon disulfide. Asphalt is a waterproof, moistureproof and anticorrosive organic cementing material. The asphalt can be mainly divided into coal tar asphalt, petroleum asphalt and natural asphalt: among them, coal tar pitch is a by-product of coking. Petroleum pitch is the residue of crude oil distillation. Natural bitumen is stored underground, and some forms a mineral layer or is accumulated on the surface of the crust. The asphalt is mainly used in the industries of paint, plastics, rubber and the like and pavement and the like.
Because the asphalt belongs to a hydrophobic material and is impermeable, the asphalt on the surfaces of a constructed metal testing instrument and a construction machine cannot be washed by clear water, and the asphalt is difficult to clean as an auxiliary machine. Therefore, the constructors often use trichloroethylene or gasoline as a solvent, and wash the soaked product. However, trichloroethylene and gasoline are volatile substances and used for soaking metal parts, so that the cost is high, the environment is easily polluted, and particularly toxic substances of trichloroethylene are harmful to human bodies; as for gasoline, because the flash point temperature is low, the explosion limit value of the gasoline mixed with air is only 1% -6%, the gasoline belongs to flammable, explosive and electrostatic ignition materials, and the use needs caution.
Disclosure of Invention
The invention aims to provide an asphalt cleaning agent and a preparation method thereof, which not only have high stability, but also have good cleaning effect on asphalt.
The above object of the present invention is achieved by the following technical solutions: the asphalt cleaning agent comprises the following components in parts by weight: 10-16 parts of surfactant, 1-3 parts of polyethylene glycol, 1-3 parts of sodium methyl benzene sulfonate, 0.5-1.5 parts of sodium metasilicate pentahydrate, 10-20 parts of EDTA-2Na3, 10-20 parts of corrosion inhibitor, 2-4 parts of isopropanol, 5-7 parts of dispersant, 3-7 parts of scale inhibitor and 44-73 parts of water.
Preferably, the composition comprises the following components in parts by weight: 13 parts of surfactant, 2 parts of polyethylene glycol, 2 parts of sodium methyl benzenesulfonate, 1 part of sodium metasilicate pentahydrate, 3.5 parts of EDTA-2Na3, 15 parts of corrosion inhibitor, 3 parts of isopropanol, 6 parts of dispersant, 5 parts of scale inhibitor and 59 parts of water.
By adopting the technical scheme, the polyethylene glycol is a solvent catalyst, can be compatible with water, and has high dissolving efficiency on the asphalt, so that the solubility of the asphalt in the water is promoted.
The isopropanol has low price, wide application range, can be freely mixed with water, has stronger dissolving capacity to lipophilic substances than ethanol, and has low freezing point, so the isopropanol is a high-efficiency antifreezing agent and is beneficial to improving the overall stability of the cleaning agent.
In addition, sodium metasilicate pentahydrate is a non-toxic, tasteless and nuisanceless white powder or crystalline particle, which is easily soluble in water, and meanwhile, the aqueous solution is alkaline, and asphalt is easily soluble in alkali. In addition, the cleaning agent has the functions of descaling, emulsification, dispersion, wetting, permeability and buffering of pH value, so that the cleaning agent can be in an alkaline state after being used for many times, and can be easily permeated into asphalt to dissolve the asphalt more quickly, and can also be helpful for dispersion of other components.
Preferably, the surfactant is a mixture of an anionic surfactant and a nonionic surfactant.
By adopting the technical scheme, the anion has wider temperature adaptation range and higher stability, and has the defect of stronger hydrophilicity. Therefore, the formula of the cleaning agent is preferably prepared by adopting a surfactant compounding technology containing nonionic and anionic, and the key is reasonable components of the nonionic and anionic surfactants, so that the nonionic and anionic surfactants can complement each other and the stability of the anionic surfactant can be improved.
Preferably, the sodium methyl benzene sulfonate is a mixture of sodium xylene sulfonate and sodium p-toluene sulfonate.
By adopting the technical scheme, the sodium xylene sulfonate is used as a solubilizer in the detergent, and is beneficial to enhancing the dissolving effect of the asphalt in the detergent. At the same time, it is also used as a component of dry cleaners, disinfectants, metal working cleaners, and the like. Sodium xylene sulfonate is used in liquid detergents as coupling agent, hydrotrope, leveling agent, dispersant, and to lower cloud point and viscosity.
The sodium xylene sulfonate is mainly used as a solubilizer in the liquid cleaning agent, and after the sodium p-toluenesulfonate is added, the viscosity and the cloud point of the cleaning agent are reduced.
The mixture of sodium xylene sulfonate and sodium p-toluenesulfonate has the characteristics of sodium xylene sulfonate and sodium p-toluenesulfonate, and the sodium xylene sulfonate and the sodium p-toluenesulfonate can be stably mixed together according to the principle of similarity and intermiscibility, so that the performances of the cleaning agent are further improved, and the asphalt cleaning agent is beneficial to more efficiently cleaning asphalt.
Preferably, the weight part ratio of the sodium xylene sulfonate to the sodium p-toluenesulfonate is 1: 0.6-1.8.
Preferably, the corrosion inhibitor is polyaspartic acid.
By adopting the technical scheme, the Polyaspartic Acid (PASP) belongs to one of polyamino acids. The peptide bond on the structural main chain of the polyaspartic acid is easy to be broken by the action of microorganisms, fungi and the like, and the final degradation products are ammonia, carbon dioxide and water which are harmless to the environment. Therefore, polyaspartic acid is an environmentally friendly chemical with good biodegradability.
And the polyaspartic acid can obtain better corrosion inhibition effect when the pH value is more than 10. When the pH value is 8-9, the polyaspartic acid with lower concentration has better corrosion inhibition effect in seawater. Therefore, when the cleaning agent is used for cleaning metal instruments or machines, the possibility of corrosion of metal surfaces can be effectively reduced.
Preferably, the dispersant is one or two of hydrolyzed polymaleic anhydride or acrylic acid-ethyl acrylate-itaconic acid copolymer.
By adopting the technical scheme, the hydrolyzed polymaleic acid and acrylic acid-ethyl acrylate-itaconic acid copolymer are both suitable for alkaline water or are compounded with other medicines for use. And the metal surface is also provided with scale inhibition and dispersion effects, so that the metal surface is not easy to generate scale after being cleaned by the cleaning agent.
Preferably, the scale inhibitor is a phosphine compound corrosion and scale inhibitor.
By adopting the technical scheme, the scale inhibitor mainly performs two functions of slowing down crystal growth and promoting lattice distortion to inhibit scale, has the characteristics of good chemical stability, wide applicable pH range, difficult hydrolysis, obvious threshold effect, capability of chelating with metal ions to form a stereo macromolecular ring complex and the like. And the corrosion inhibitor is compounded with polyaspartic acid, hydrolyzed polymaleic acid or acrylic acid-ethyl acrylate-itaconic acid copolymer, so that the corrosion inhibition performance of polyaspartic acid can be greatly enhanced, and the possibility of corrosion of metal after cleaning is further reduced.
Preferably, the phosphine compound corrosion and scale inhibitor is one or two of diethylenetriamine pentamethylene phosphonic acid or hexamethylenediamine tetramethylene phosphonic acid.
By adopting the technical scheme, the scale and corrosion inhibition effects of the diethylenetriamine pentamethylene phosphonic acid and the hexamethylenediamine tetramethylene phosphonic acid are good, the temperature resistance is good, the production of carbonate, sulfate and phosphate scales can be inhibited, and particularly in an alkaline solution, the scale and corrosion inhibition performance is good compared with that of calcium carbonate when the pH value is 10-11.
