Description
Technical Field
The invention relates to the technical field of surface treating agents, and particularly relates to wax removing water as well as a preparation method and application thereof.
Background
After the surfaces of ceramic tiles, metal workpieces, artware and ornaments are polished, a large amount of wax scale of polishing wax is remained on the surfaces of the ceramic tiles, the metal workpieces, the artware and the ornaments, the wax scale mainly comprises stearic acid, palmitic acid, oleic acid, rosin, inorganic metal oxide and inorganic solid polishing small particles with extremely high logP values (which refer to logarithmic values of distribution coefficients of certain substances in n-octanol and water), the inorganic metal oxide and the inorganic solid polishing small particles are attached to the surfaces of the workpieces in modes of intermolecular adsorption, electrostatic adsorption and the like, and the wax scale is difficult to remove when the diameter of the wax scale is less than 0.1 mu m. The wax scale is required to be thoroughly cleaned before delivery or next treatment, the wax removing water is a cleaning agent capable of effectively removing the wax scale on the surfaces of ceramic tiles and metals, and the key of preparation of the wax removing water is to reasonably compound various surfactants, auxiliaries, corrosion inhibitors and cosolvents. The wax removing water improves the wetting permeability and the emulsifying, dissolving and dispersing solubilization properties by reducing the surface tension, thereby enhancing the permeability and the dissolving power of the wax removing water on wax scales and achieving the purpose of quickly removing the wax scales.
The common method for using the paraffin removal water is to put the workpiece into the paraffin removal water for standing, and make the paraffin adhesive fall off from the surface of the workpiece into the paraffin removal water by using ultrasonic waves or stirring. However, hydrochloric acid, sulfuric acid, oxalic acid, organic alkali and inorganic alkali contained in common de-waxing water in the market at present are mismatched with the used auxiliary agent and corrosion inhibitor, so that the de-waxing water corrodes the tank body of the ultrasonic equipment, has low cleaning efficiency, damages the smoothness of the surface of a workpiece and other consequences.
Therefore, the development of the paraffin removal water which has good paraffin removal effect, is easy to clean and does not corrode ultrasonic cleaning equipment is urgently needed.
Disclosure of Invention
The invention aims to provide wax removing water, which solves one or more technical problems in the prior art and provides at least one beneficial choice or creation condition.
The technical scheme adopted for solving the technical problems is as follows:
the wax removing water comprises the following components in parts by weight: 1-10 parts of modified PVA composite material, 12-53 parts of surfactant and 50-80 parts of deionized water, wherein the modified PVA composite material comprises PVA and reduced graphene oxide positioned in PVA pores.
Preferably, the wax removing water comprises the following components in parts by weight: 1-4 parts of modified PVA composite material, 20-34 parts of surfactant and 55-75 parts of deionized water, wherein the modified PVA composite material comprises PVA and reduced graphene oxide positioned in PVA pores.
The invention has the beneficial effects that the wax removing water is neutral, has good protection effect on various ferrous metals and nonferrous metal products, and plays good roles in inhibiting corrosion and preventing oxidation in the cleaning process. It is worth noting that 300 parts by weight of water is added for dilution when the wax removing water provided by the invention is used.
The wax removing water mainly has the following uses:
1. the cleaning agent is used for cleaning stubborn heavy oil stains on the surfaces of mechanical equipment and machine tools;
2. the cleaning agent is used for cleaning crude oil dirt and oil sludge on a drilling platform, a crude oil pipeline and a storage tank;
3. the cleaning agent is used for cleaning various coal tar pipelines, intercoolers and oil-gas separators of a coking plant;
4. the cleaning agent is used for replacing various hydrocarbon cleaning agents (flammable and explosive);
5. the degreasing and cleaning agent is used for degreasing and cleaning in the electroplating industry;
6. is used for degreasing and cleaning in the automobile industry.
Preferably, the surfactant is a mixture of 5-15 parts by weight of sodium dodecyl benzene sulfonate, 5-20 parts by weight of coconut oil fatty acid diethanol amide, 1-8 parts by weight of alkanolamide phosphate and 1-10 parts by weight of cocamidopropyl betaine.
Preferably, the surfactant is 7-10 parts of sodium dodecyl benzene sulfonate, 10-15 parts of coconut oil fatty acid diethanol amide, 2-5 parts of alkanolamide phosphate and 1-4 parts of cocamidopropyl betaine according to parts by weight.
The sodium dodecyl benzene sulfonate, the coconut oil fatty acid diethanolamide, the alkanolamide phosphate and the cocamidopropyl betaine are matched to be used as the composite surfactant, so that the composite surfactant is small in irritation, easy to dissolve in water, stable to acid and alkali, high in foam, strong in detergency, good in emulsifying effect and obvious in thickening effect, and can effectively remove various oil stains in the polishing wax.
The components of the invention are as follows:
the reduced graphene oxide is a carbon nano two-dimensional material, has strong adsorption effect, and can adsorb various atoms and molecules. In addition, the reduced graphene oxide has good solubility in a non-polar solvent, and has super-hydrophobicity and super-lipophilicity.
PVA is the abbreviation of polyvinyl alcohol, is nontoxic, biodegradable, cheap and easily available. PVA has a chemical structure of polyol and thus can be modified by chemical crosslinking, and is often used to make various types of porous materials, hydrogels, and aerogels. The reduced graphene oxide can be loaded in the pores of the PVA. Because the density of the modified PVA/graphene composite material is higher than that of water, the modified PVA/graphene composite material is easy to sink to the bottom when being independently placed in de-waxing water, and under the action of surfactants such as sodium dodecyl benzene sulfonate, coconut oil fatty acid diethanolamide and cocamidopropyl betaine, waxy adherends can also fall off from workpieces and suspend in the de-waxing water. The adsorption of the reduced graphene oxide on the oil mixture can reach more than 100 times of the self weight, so that the organic mixture of the oil such as paraffin, fatty acid and the like suspended in the paraffin removal water can be completely adsorbed by the reduced graphene oxide; the residual rosin soap in the adhesive can play a role in washing the workpiece, and the residual metal oxide and certain inorganic solid polishing small particles can sink to the bottom of the paraffin removal water, cannot be adhered to the surface of the workpiece, and can be cleaned only by filtering.
The reduced graphene oxide can float on the water surface with the modified PVA/graphene composite material after absorbing oil, so that the modified PVA/graphene composite material floating on the water surface only needs to be caught, and the catching and the recycling are easy. And the modified PVA/graphene composite material after oil absorption can adopt methods such as centrifugal separation, heating extraction and the like to separate the oil in the modified PVA/graphene composite material, so that the aim of recycling is achieved, and the recycling treatment is simple and convenient.
Meanwhile, PVA belongs to a common pollution adsorbent and is biodegradable, and main elements of the reduced graphene oxide are carbon, oxygen and hydrogen, so that the PVA and the reduced graphene oxide cannot form secondary pollution, the pollution degree of wax removing water is reduced, and the subsequent treatment process is shortened.
According to the invention, after the oil mixture is separated from the paraffin removal water, the reduced graphene oxide is taken as a carrier and suspended on the liquid surface of the paraffin removal water, so that the oil mixture is convenient to catch and recycle; and metal oxides and certain inorganic solid polishing small particles falling on the wax removing water bottom can be removed only by filtering, so that the subsequent separation process is reduced, and the subsequent treatment step of the wax removing water is simplified.
Preferably, the preparation method of the modified PVA composite material comprises the following steps:
the method comprises the following steps: placing graphite oxide in a crucible, and adding N2The protected box-type resistance furnace is expanded for 30s at the high temperature of 1000 ℃, and then is taken out quickly to obtain graphene with the particle size smaller than the pore diameter of PVA;
step two: under the heating of water bath at 95 ℃, 6g of polyvinyl alcohol with the model number of 2699 is dissolved into 54g of deionized water to prepare 10 wt% of polyvinyl alcohol solution;
step three: putting 5.36g of the polyvinyl alcohol solution obtained in the second step into a beaker, adding the graphene obtained in the first step into the polyvinyl alcohol solution, wherein the mass ratio of the solid of the graphene to the solid of the polyvinyl alcohol is 0.12, and adding a proper amount of water to adjust the solid content to 3.33 wt% to obtain a mixed solution;
step four: adding soluble starch into the mixed solution obtained in the third step, mechanically stirring, adding 3g of formaldehyde and 50 wt% of concentrated sulfuric acid aqueous solution, and stirring until the mixed solution has certain viscosity to obtain a precursor;
step five: and pouring the precursor obtained in the fourth step into a mold, sealing, curing at 60 ℃, washing with water for more than three times, and freeze-drying to obtain the modified PVA composite material.
By adopting the preparation method, in the high-temperature reduction process of the modified PVA composite material, oxygen-containing groups such as carboxyl, hydroxyl, epoxy and the like in the structure of the graphite oxide material are damaged, so that the contact angle of the reduced graphene oxide in water is larger than that of the graphite oxide. In addition, the single-layer graphene can provide a primary roughness, and the gaps between the sheets generate a secondary roughness, so that air sacs can enter a rough structure, and then an air film is formed on the surface of the reduced graphene oxide to prevent water drops from permeating, so that the reduced graphene oxide has excellent super-hydrophobicity and super-lipophilicity. PVA is generally obtained by alcoholysis of PVAc (polyvinyl carboxylic acid), so that PVA has the characteristic of easy hydrolysis, but graphene/polyvinyl formal is obtained by crosslinking and modifying PVA with formaldehyde through the technical scheme, so that the problems of easy hydrolysis, easy water absorption and expansion and the like of PVA are effectively solved.
Preferably, in the fifth step, the precursor obtained in the fourth step is subjected to ultrasonic treatment, and then poured into a mold, wherein the frequency of the ultrasonic treatment is 20kHz-25kHz, and the time is 10-15 min. The reduced graphene oxide can be vibrated into a PVA pore channel with the outer diameter slightly larger than that of the reduced graphene oxide through ultrasonic treatment, and the reduced graphene oxide in the PVA pore channel can migrate to the interior of the pore channel of the PVA, so that the graphene loading rate in the PVA pore channel is improved.
Preferably, nanometer magnesium peroxide is loaded in the pore channels of the reduced graphene oxide. Because water is required to be added for dilution when wax removing water is used, the nano magnesium peroxide reacts with water in water to generate magnesium hydroxide and release oxygen, and the oxygen can give an opposite impact force to the modified PVA composite material after being sprayed out of the pore channels of the reduced graphene oxide, so that the modified PVA composite material can move in water, and the oil absorption efficiency of the modified PVA composite material is further improved. Meanwhile, the magnesium hydroxide generated after the reaction of the nano magnesium peroxide with water can coat the nano magnesium peroxide, so that the rate of oxygen generation in the subsequent process is reduced, the service life of the nano magnesium peroxide is prolonged, and the oil absorption stability of the modified PVA composite material is further improved.
Preferably, the preparation method of the graphene loaded with the nano magnesium peroxide in the pore channel comprises the following steps:
the method comprises the following steps: adding nano magnesium peroxide into kerosene, and uniformly stirring to obtain nano magnesium peroxide coating liquid;
step two: adding the modified PVA composite material into the nano magnesium peroxide coating solution and stirring for more than 10 min;
step three: and (3) centrifuging and drying the nano magnesium peroxide coating solution with the modified PVA composite material.
Because the nano magnesium peroxide is insoluble in kerosene, the surface of the nano magnesium peroxide is coated by the kerosene to form a nano magnesium peroxide coating solution, and after the modified PVA composite material is added into the nano magnesium peroxide coating solution, the reduced graphene oxide in the modified PVA composite material can absorb the kerosene, and simultaneously, the nano magnesium peroxide coated by the kerosene is absorbed together and enters the pore canal of the reduced graphene oxide. And then, centrifuging to separate the kerosene coated on the surface of the nano magnesium peroxide to obtain the reduced graphene oxide loaded with the nano magnesium peroxide in the pore channel.
In the centrifugal process, although part of the nano magnesium peroxide is thrown out of the pore channels of the reduced graphene oxide, most of the nano magnesium peroxide is still located in the pore channels of the reduced graphene oxide. And the thrown-out nano magnesium peroxide can generate oxygen after being diluted by wax removing water and water, and the modified PVA composite material can move in the escaping process of the oxygen, so that the oil absorption efficiency of the modified PVA composite material is improved.
Preferably, the wax removing water further comprises 3-5 parts of a dispersing agent and/or 9-10 parts of a corrosion inhibitor in parts by weight. The dispersant can separate the modified PVA composite materials from each other in the wax removal water, avoids the modified PVA composite materials from agglomerating in the wax removal water, and has the functions of chelating, emulsifying, buffering pH and the like on metal ions; sodium tripolyphosphate can be selected as the dispersant. The corrosion inhibitor can prevent the surface of the workpiece from being corroded by the paraffin removal water, so that the quality of the workpiece is ensured; the corrosion inhibitor can be diethanolamine.
The second purpose of the invention is to provide the preparation method of the dewaxing water, which is to uniformly mix the sodium dodecyl benzene sulfonate, the coconut oil fatty acid diethanol amide, the alkanolamide phosphate, the cocamidopropyl betaine and the deionized water in corresponding parts by weight, add the modified PVA composite material, add the dispersing agent and/or the slow release agent according to the actual use requirement, and uniformly stir to obtain the dewaxing water.
The third purpose of the invention is to provide the application of the wax removing water in the field of equipment cleaning.

the total amount of wax contained in the paraffin removal water of the test samples 1-4 and the control samples 1-3 is 2.81-2.85mL, and the oil adsorption amount of the modified PVA composite material in the test samples 1-4 shows that the modified PVA composite material can absorb 2.31-2.37mL of oil, which reaches more than 81% of the oil contained in the paraffin removal water, the oil adsorption amount is large, the control samples 1 and 2 do not contain the modified PVA composite material and have no oil adsorption capacity, and the oil adsorption capacity of the control sample 3 is greatly reduced and only 0.34mL of oil is absorbed because graphene is replaced by active carbon. Therefore, after the modified PVA composite material is added into the paraffin removal water, a large amount of oil mixtures suspended in the paraffin removal water can be adsorbed, and when the modified PVA composite material floats out of the paraffin removal water, the modified PVA composite material is convenient for workers to recover, so that the subsequent separation procedures are reduced, and the subsequent treatment steps of the paraffin removal water are simplified.
Comparing the test sample 5 with the test samples 1-4, wherein the oil adsorption amount of the modified PVA composite material of the test sample 5 added with the nano magnesium peroxide is 2.36 mL; the oil adsorption amount of the modified PVA composite material in the test samples 1-4 without the nano magnesium peroxide is 2.12-2.18mL, which is lower than that of the test sample 5, and the oil adsorption efficiency of the modified PVA composite material can be improved after the nano magnesium peroxide is loaded in the pore channels of the modified PVA composite material.
As can be seen from the comparison of the test sample 6 with the test samples 1 to 5, the corrosion amount of the test sample 6 added with the corrosion inhibitor to the steel sheet is 0.35 mg; the corrosion amount of the test samples 1-5, the comparison samples 1-4 and the comparison sample 6 which are not added with the corrosion inhibitor to the steel sheet is 3.11-3.13mg, so that after the corrosion inhibitor is added, the corrosion amount of the paraffin removal water to the steel sheet is reduced by more than 89%, the corrosivity of the paraffin removal water is reduced, and the quality of the workpiece is ensured.
As can be seen from the comparison of the test sample 7 with the test samples 1 to 4, the oil adsorption amount of the modified PVA composite material of the test sample 7 added with the dispersant is 2.53 ml; the oil adsorption amount of the modified PVA composite material is 2.31-2.36ml in the test samples 1-4, the test sample 6 and the control sample 5 which are not added with the dispersing agent, so that the oil adsorption amount of the wax removing water is improved by more than 7% after the dispersing agent is added, which shows that the dispersing agent improves the dispersion degree of the modified PVA composite material in the wax removing water, and further improves the oil adsorption capacity of the wax removing water.
As can be seen from the comparison of the test sample 8 with the test samples 1-5 and the test sample 7, after the dispersing agent and the nano magnesium peroxide are simultaneously added, the adsorption capacity of the test sample 8 to the oil reaches 2.82ml, which is 99.3 percent of the total amount of the wax in the wax removing water; in the test samples 1-4 without the dispersant and the nano magnesium peroxide, the oil adsorption amount of the modified PVA composite material is 2.31-2.36ml, which is 81.3% -82.8% of the total amount of the wax in the wax removing water; the oil adsorption amount of the modified PVA composite material is 2.54ml and is 90.0 percent of the total amount of the wax in the wax removing water; in test sample 7 to which the dispersant was added alone, the amount of adsorbed oil in the modified PVA composite was 2.53ml, which is 89.4% of the total amount of wax in the paraffin-removed water. The nano magnesium peroxide and the dispersing agent are added simultaneously, so that the synergistic promotion effect is achieved on the oil adsorption capacity of the wax removing water, and most of wax in the wax removing water can be adsorbed.
