Description
Technical Field
The invention relates to the technical field of cleaning agents, and particularly relates to an atomized cleaning agent and a preparation method thereof.
Background
A detergent, which is a cleaning product in a liquid state for washing clothes, or cleaning utensils, or cleaning furniture, etc. It adopts several new surfactants, and has strong detersive power, easy rinsing and no irritation to skin. With the increase of economy, automobiles become a part of daily life of people, the automobiles need to be washed irregularly, dirt such as oil stain cannot be removed by clear water, and the dirt can be removed by using a conventional automobile cleaning agent, but the conventional automobile cleaning agent has strong corrosivity on the automobiles, so that the paint surface loses gloss, loses rust and the like, and the abrasion is brought to the automobiles.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and provides an atomized cleaning agent which is provided with a surfactant capable of emulsifying dirt to achieve a quick cleaning effect, a builder capable of being matched with the surfactant to increase the cleaning effect and keep the solution balance, a composite corrosion inhibitor capable of preventing the metal surface from being corroded when being cleaned, and a friction agent capable of penetrating into a brake device to rub with the dirt in a gap to increase the cleaning effect.
The purpose of the invention is realized by the following technical scheme:
an atomized cleaning agent, which is characterized in that: the feed comprises the following raw materials in parts by weight:
the atomized cleaning agent provided by the invention is provided with the surfactant, can emulsify dirt to achieve a quick cleaning effect, the builder can be matched with the surfactant to increase the cleaning effect and keep the solution balance, the composite corrosion inhibitor is arranged, the metal surface can be prevented from being corroded when being cleaned, and the abrasive is arranged and can penetrate into the gap to rub against the dirt in the gap, so that the cleaning effect is increased. The ethanol and the propanol have lower boiling points, are easy to atomize, so that the cleaning agent forms fine particles, does not damage the surface of the automobile, and has good emulsification cleaning effect.
The preparation method of the low surface tension water comprises the following steps: deionized water is irradiated by far infrared ray of 10-20 μm for 3-5 hr to obtain low surface tension water. Light having a medium wavelength range of 1.5 to 400 μm is called far infrared ray. The far infrared ray has strong penetrating power and radiation power, has obvious temperature control effect and resonance effect, and is easy to be absorbed by object and converted into internal energy of object. The far infrared ray adopted in the invention radiates the deionized water, the wavelength of the far infrared ray is within the range of 10-20 μm, the resonance effect with water is good, and the resonance effect enables water molecules to generate a resonance absorption effect, on one hand, because the electromagnetic wave of the far infrared ray resonates with the water molecules, hydrogen bonds among the water molecules are destroyed, the association degree of the water molecule groups is reduced, on the other hand, the vibration and the rotation of the water molecules are aggravated, the energy of movement is increased, the water molecules are changed into small water molecules, and the activated water with lower surface tension is obtained. The low surface tension activated water obtained by far infrared radiation treatment has higher surface energy than common deionized water, has smaller contact angle with the metal surface, and has better wetting effect on the metal surface, so that the water can automatically enter between dirt and glass in a 'clipping' shape, and the dirt is stripped from the metal surface under the washing action of the cleaning agent. Thereby reducing the addition of the surfactant on the premise of ensuring the same cleaning capability. Specifically, when the surfactant is dissolved in water with low surface tension, the emulsifying effect of the surfactant can be increased, so that stains are easier to emulsify and remove, and the foaming height is greatly reduced. Specifically, the compatilizer is a styrene-maleic anhydride copolymer, and preferably the styrene-maleic anhydride copolymer with the mass percent of maleic anhydride of 15-25 wt.%, so that the compatibility of the composite corrosion inhibitor and the surfactant can be improved.
Wherein the surfactant is dodecyl polyoxyethylene ether sodium sulfate, polyether modified polysiloxane and hexadecyl dimethyl ammonium chloride, and the weight parts are (1-5): (2-6): (0.1-1.2). The traditional cleaning agent is compounded by using a single type of surfactant, the compounded emulsifying effect is poor, the nonionic surfactant has the characteristic of low cloud point, and when the temperature is higher than the cloud point temperature, the nonionic surfactant can be separated out from the cleaning agent, so that the emulsifying and decontaminating capability is lost. The polyether modified polysiloxane is used, so that the cloud point is effectively improved, the emulsification effect is increased, the compounded surfactant has a high-efficiency emulsification cleaning effect, the cloud point is high, and the application range is wide. The invention uses the anion surfactant, the cation surfactant and the nonionic surfactant for compounding, greatly improves the emulsification effect, and the prepared cleaning agent has higher cloud point with the cloud point temperature reaching 66 ℃, so that the cleaning agent can clean the high-temperature glass even if the automobile windshield is exposed under the sun for a long time.
The preparation method of the modified titanium dioxide comprises the following steps:
s1, taking 7-10 parts of acetic acid and 5-8 parts of ethanol, and uniformly stirring to obtain a solution A;
s2, controlling the reaction temperature, dropwise adding 1-3 parts of isopropyl titanate into the solution A, uniformly stirring, heating for drying, cooling and centrifuging to obtain the modified titanium dioxide.
According to the invention, the hydrothermal method is used for preparing the nano titanium dioxide, the titanium dioxide prepared by the method has good monodispersity, the titanium dioxide is in a hollow sphere shape, the average diameter of the hollow sphere of the titanium dioxide is about 500 nanometers, a cavity with the diameter of about 140 nanometers is arranged in the middle of the hollow sphere of the titanium dioxide to form the hollow sphere of the titanium dioxide, the shell has certain mechanical hardness, and the flowing hollow sphere of the titanium dioxide can rub against a mixture of dust and oil stains on the surface of metal, so that the mixture of the dust and the oil stains is separated from an engine, and the physical cleaning effect is achieved. The use amount of the organic acid is very important for the formation of the hollow spheres of the nano titanium dioxide, namely when the use amount of the acetic acid is too small, the reaction rate of the hydrolytic condensation of the whole reaction system is too fast and uncontrolled, the diameter of the titanium dioxide hollow spheres which are easy to form is too large, even a hollow hemispherical structure appears, and the friction with carbon deposition is not facilitated; when the usage amount of the acetic acid is too large, a large amount of the acetic acid surrounds the titanium dioxide nano particles, the mutual combination growth among the nano particles is blocked, and meanwhile, the adhesion phenomenon occurs among the titanium dioxide hollow spheres, so that the titanium dioxide hollow spheres cannot form a proper size.
Wherein the reaction temperature in the step S2 is 130-200 ℃. The reaction temperature is very important for the size of the nano titanium dioxide, 130-200 ℃, when the temperature is lower than 130 ℃, titanium dioxide hollow spheres generated by the reaction are not separated from each other, a certain degree of adhesion phenomenon exists, when the temperature is higher than 200 ℃, the diameter of the titanium dioxide hollow spheres of the reaction organism is increased, the hollow spheres are collapsed, a plurality of hollow titanium dioxide hemispherical structures are generated, the titanium dioxide hollow spheres cannot be formed, and therefore the reaction temperature needs to be strictly controlled.
Wherein the composite corrosion inhibitor comprises modified polyaspartic acid, sodium molybdate, hydroxyethylidene diphosphonic acid and zinc sulfate according to the mass ratio of (2-6): (9-15): (2-6): (15-20). Oxygen atoms on five hydroxyl groups on the hydroxyethylidene diphosphonic acid can be chemically adsorbed with iron ions on the surface of the metal to form coordinate bonds, a chelate film is generated to be attached to the surface of the metal, and the diffusion of dissolved oxygen to the surface of the metal is favorably prevented, so that the corrosion of the metal is inhibited. Zinc sulfate can be combined with reduction products to form a surface compound Zn (OH) which is difficult to dissolve or insoluble on the metal surface2And the corrosion inhibitor is attached to the surface of the metal, so that the further corrosion of the metal is prevented. The sodium molybdate belongs to one of anode type corrosion inhibitors, has good stability and can form a passivation film with iron ions and ferric trioxide. When the four raw materials are compounded according to a certain mass ratio, the corrosion inhibition effect is better, and preferably, when the modified polyaspartic acid, the sodium molybdate, the hydroxyethylidene diphosphonic acid and the zinc sulfate are compounded according to the mass ratio: 4: 11: 5: and 17, the corrosion inhibition effect of the composite corrosion inhibitor is optimal and reaches 99.78%.
Wherein, the builder comprises a mixture of more than two of trisodium phosphate, sodium silicate, sodium carbonate and benzotriazole. The builder has a chelating effect on metal ions, softens hard water, has a buffering effect, can maintain the stability of the pH value in the cleaning agent, has a dispersing effect on fixed dirt, can prevent the dirt from being reattached on a workpiece, can improve the cleaning capability of the cleaning agent when being mixed with a surfactant, and also has good effects of preventing corrosion and rusting. The trisodium phosphate, when hydrolyzed, produces phosphoric acid of very low solubility, thus achieving basicity. The trisodium phosphate has the function of softening hard water, has the function of obviously promoting the dispersion and emulsification of dirt particles, has higher alkalinity, and can dissolve fat dirt through saponification. Meanwhile, the trisodium phosphate and sodium dodecyl benzoate in the surfactant have obvious synergistic effect, and the cleaning effect can be greatly improved when the trisodium phosphate and the sodium dodecyl benzoate are used in a composite way. Sodium silicate forms stable colloids in water to form solvated micelles, and has good washing-assistant effect when used together with a surfactant. The micelle has a dispersing effect on solid dirt particles, is beneficial to preventing the dirt from being reprecipitated on the solid surface, and simultaneously, the silicate has a buffering effect and can maintain the pH stable and unchanged. Sodium carbonate can be hydrolyzed to generate hydroxide radical, and has buffering effect on solution pH. Benzotriazole can be adsorbed on the surface of metal to form a thin film to protect copper and other metals from corrosion by atmosphere and harmful media. The multiple builders can increase the emulsification effect of the surfactant, increase the cleaning effect, have the buffering effect, maintain the pH balance of the solution and prevent the corrosion of the metal surface by the composite use.
The invention aims to provide a preparation method of an atomized cleaning agent, which is simple to operate, stable in production quality, capable of realizing mass production and strong in practicability, aiming at the defects in the prior art.
The purpose of the invention is realized by the following technical scheme:
the preparation method of the atomized cleaning agent comprises the steps of adding the surfactant, the abrasive, the composite corrosion inhibitor, the builder, the ethanol and the propanol in parts by weight into low-surface-active water, stirring at the rotating speed of 100-500r/min for 10-40min, and uniformly mixing.
