Description

TECHNICAL FIELD

[0001] The present application relates to the field of cleaning sprays, more particularly, it relates to an aerosol type residual adhesive cleaner and a preparation method thereof. BACKGROUND

[0002] In the field of automotive beauty and maintenance, the attachment and removal of car films is a common operation. As a means of decoration and protection, car films can effectively protect the car paint from the external environment, while providing personalized appearance. However, as time goes by and the car film ages, the car owner may choose to tear off the old car film to replace it with a new one or to restore the original paint.

[0003] In the process of tearing off the car film, a common problem is that the car film leaves residual adhesive on the paint that is difficult to remove. These residual adhesives not only affect the appearance of the car, but also become an obstacle to subsequent film attachment operations. If the residual adhesive cannot be completely removed, the newly attached car film may have problems such as bubbling, unevenness, etc., which seriously affect the film attachment effect and service life.

[0004] To solve this problem, a variety of residual adhesive cleaners have appeared on the market. However, the existing cleaners generally have the problem of unsatisfactory cleaning effect. Some cleaners have weak solubility for residual adhesive, and repeated use is required to achieve a certain cleaning effect, which not only increases the use cost, but also prolongs the operation time. Therefore, there is still room for improvement. SUMMARY

[0005] In order to enhance the cleaning effect of car film residual adhesive, the present application provides an aerosol type residual adhesive cleaner and a preparation method thereof.

[0006] In the first aspect, the present application provides an aerosol type residual adhesive cleaner, which adopts the following technical solution:

[0007] An aerosol type residual adhesive cleaner, according to mass percentage, includes the following components: toluene 20-35%, limonene 1-10, cyclohexanone 0.1-5%, propellant 20-35%, and solvent to make up the rest to 100%.

[0008] By adopting the technical scheme, the toluene, limonene and cyclohexanone cooperate with each other to produce a good cleaning effect. When the cleaning agent is sprayed on the residual glue surface, the toluene first contacts the hard surface layer of the residual glue and quickly softens and dissolves the residual glue in the hard surface layer by the dissolving effect. After the toluene dissolves the hard surface layer of the residual glue, the cyclohexanone starts to play its unique penetrating and dissolving effect. The cyclohexanone can penetrate into the internal structure of the residual glue and further dissolve the softened residual glue. This penetrating and dissolving mode can ensure that the residual glue is completely removed without leaving any trace. The limonene, as a natural extract, not only has a fresh smell and can adjust the overall smell of the cleaning agent to make it more pleasant, but also has a certain cleaning effect and can assist the toluene and the cyclohexanone in removing the residual glue. In addition, the addition of the limonene also makes the cleaning agent more environmentally friendly and safe.

[0009] The toluene, limonene and cyclohexanone cooperate with each other in the cleaning agent to form a unique cooperative mechanism.

[0010] Since the residual glue often has certain adhesion and hardness, ordinary solvents are difficult to effectively dissolve in a short time. The toluene, which first contacts the residual glue on the paint surface, can quickly dissolve the hard surface layer of the residual glue by using its strong dissolving power, forming a loose material structure. This step is like opening a crack in the hard armor, providing good conditions for the subsequent penetration and dissolution of the solvent.

[0011] After the toluene dissolves the hard surface layer of the residual glue, the cyclohexanone starts to play its unique penetrating and dissolving effect. As a solvent with excellent penetrating ability, the cyclohexanone can quickly penetrate into the internal structure of the residual glue which has been loosened along the crack opened by the toluene. On the basis of the dissolution of the toluene, the cyclohexanone further dissolves the gum components in the residual glue, making it completely separate from the paint surface. This penetrating and dissolving mode ensures that the residual glue is completely removed without leaving any trace.

[0012] The limonene not only plays a role in adjusting the smell, making the cleaning agent more pleasant, but also has a certain auxiliary cleaning effect. Under the action of the toluene and the cyclohexanone, the residual glue has been greatly decomposed, but there may still be some stubborn gum residues. At this time, the cleaning effect of the limonene is particularly important. It can assist the toluene and the cyclohexanone to remove those difficult-to-remove gum residues.

[0013] Through the cooperation of the toluene, the cyclohexanone and the limonene, the cleaning agent can quickly dissolve and remove the hard residual glue, greatly saving the cleaning time. The use of the natural extract limonene as an auxiliary ingredient makes the cleaning agent more environmentally friendly and safe, and its fresh smell also improves the comfort of use.

[0014] The cleaning agent adopts an aerosol form, is convenient to use without special equipment or operation skills; meanwhile, its good permeability and solubility also make the cleaning process more relaxed.

[0015] Preferably, according to the mass percentage, the toluene is 25-30%, the limonene is 5-8, the cyclohexanone is 1-3%, the propellant is 25-30%, and the solvent makes up the rest to 100%.

[0016] Preferably, according to the mass percentage, the toluene is 28.53%, the limonene is 6.42%, the cyclohexanone is 2.14%, the propellant is 28.67%, and the solvent is 34.24%.

[0017] By adopting the technical scheme, the amount range of each raw material in the system is further optimized, so that toluene, cyclohexanone and limonene can fully play a synergistic effect, and the film residue on the car can be quickly and completely removed.

[0018] Preferably, the propellant is one or more of dimethyl ether, trichloromonofluoromethane, difluoromethane and trichlorotetrafluoroethane.

[0019] Preferably, the propellant is dimethyl ether.

[0020] The propellant is the source of spray power of the aerosol. When the valve is opened, the propellant will rapidly vaporize due to the sudden pressure drop, and the medicine in the container will be sprayed out in the form of mist by the pressure of the propellant.

[0021] By adopting the technical scheme, the type of the propellant is further limited, so that toluene, cyclohexanone and limonene can be fully miscible in the specific propellant, and then play a synergistic effect. Subsequently, the solvent can be quickly released to form a fine spray and uniformly act on the film residue on the car.

[0022] Preferably, the solvent is 200# solvent oil.

[0023] In the cleaning process of the paint residue on the car, the evaporation rate of the solvent is a key factor. If the solvent evaporates too fast, it cannot fully penetrate and stay in the paint residue on the car, resulting in poor cleaning effect. Since the 200# solvent oil has a moderate evaporation rate and excellent solubility, it can ensure that the cleaning agent has enough residence time on the paint residue on the car and cooperates with other solvents to a certain extent, which affects the evaporation speed of toluene, limonene and cyclohexanone, provides enough time for the cleaning process, and achieves a significant cleaning effect. More effectively remove the residue on the car paint and restore the gloss of the car paint.

[0024] The various solvents in the cleaning agent often need to cooperate with each other to achieve the best cleaning effect. The 200# solvent oil can effectively dissolve other solvents together to form a stable system as a basic solvent. This dissolution performance ensures that the various components in the cleaning agent can fully play their roles and act together on the paint residue.

[0025] Due to the sufficient residence time of the cleaning agent on the paint, the use of a specific 200# solvent oil as a solvent can completely remove the residue without damaging the paint. This not only protects the paint from chemical corrosion and physical damage, but also prolongs the service life of the paint.

[0026] In a second aspect, the application provides a preparation method of an aerosol type residue cleaning agent, which adopts the following technical scheme: a preparation method of an aerosol type residue cleaning agent, comprising the following steps:

[0027] Step 1: stirring the solvent, toluene, limonene and cyclohexanone until uniform to obtain a semi-finished product;

[0028] Step 2: filling the semi-finished product and propellant into an aerosol container to obtain a finished product.

[0029] Preferably, in step 1, the stirring is carried out at a speed of 500-800 r / min.

[0030] The preparation method of the cleaning agent provided by the application is simple, convenient and fast, reduces production cost, and various raw materials can be fully mixed, which plays a significant cleaning and removal effect on the paint residue.

[0031] In summary, the application has the following beneficial effects:

[0032] 1. The cleaning agent is prepared by toluene, limonene and cyclohexanone, which has excellent cleaning effect on hard residue, especially suitable for cleaning paint residue. With the improvement of environmental awareness and the development of green chemistry, this efficient cleaning agent has broad market prospects.

[0033] 2. The synergistic cooperation of toluene, cyclohexanone and limonene makes the cleaning agent have good permeability, can quickly penetrate into the interior of the residue, and can quickly dissolve and remove hard residue, significantly shorten the cleaning time, improve the work efficiency and reduce the labor cost.

[0034] 3. The cleaning agent of the application uses preferred raw materials, so that the raw materials can be well dissolved together, effectively preventing fast evaporation and prolonging the action time of the cleaning agent. BRIEF DESCRIPTION OF DRAWINGS

[0091] Performance detection test

[0092] 1, residual glue removal effect: prepare 30 new car films on the market, randomly shuffled into 10 groups, 1 group 3 car films, 1 group corresponds to any one of aerosol type residual glue cleaning agent of example 1-6, comparative example 1-4.

[0093] Car film 1 includes release paper layer 11, glue layer 12 and PVC film layer 13, separate release paper film layer 11 and glue layer 12, PVC film layer 13, so that the glue layer 12 is upward. Then use aerosol type residual glue cleaning agent to aim at the glue layer 12 and evenly spray, so that the surface of the glue layer 12 is completely wet, wait for 5 min, shovel the surface of the glue layer 12.

[0094] Observe the separation of the glue layer 12 and the PVC film layer 13, if the separation of the 3 car films in the same group is similar or consistent, it is determined as the result of this group; if the separation of the 3 car films in the same group is quite different, repeat the test with 5 car films, and the separation condition with more times is the result of this group. Record the separation condition in table 2.

[0095] 2, volatilization speed detection: spray the aerosol type residual glue cleaning agent of example 1-6, comparative example 1-4 into a transparent container, and mark the mark line on the outer wall of the container according to the liquid level of the cleaning agent.

[0096] Place it in the room for 6 hours, and then observe the liquid level of the cleaning agent again after taking it out, compare the difference with the initial mark line, and record the results in table 2.

[0097]

[0098]

[0099] Comparative examples 1-3 are based on example 1, any one of toluene, limonene, cyclohexanone is replaced by other raw materials, and comparative example 4 is based on example 4, which destroys the special amount of toluene, limonene and cyclohexanone in the system.

[0100] From the detection results of Table 2, it can be seen that the aerosol type residual adhesive cleaning agents of Examples 1-6 can easily shovel off the glue layer 12 from the PVC film layer 13, and there is no obvious or no residue. Although the aerosol type residual adhesive cleaning agents of Comparative Examples 1-4 can separate a part of the glue layer 12 from the PVC film layer 13, it is more difficult to use, and the separation effect is not good, and there is more or a lot of residue, which is not clean.

[0101] It is shown that under the joint action of toluene, limonene and cyclohexanone, the prepared aerosol type residual adhesive cleaning agent can quickly contact the surface of the glue layer 12, soften and dissolve the glue layer 12, and quickly penetrate into the inside of the glue layer 12, so that the internal structure of the glue layer 12 is more loose, quickly separates from the adherend, and has no residue. The special selection of toluene, limonene and cyclohexanone in the system and the dosage matching relationship cannot be arbitrarily destroyed, and it is a special organic whole. The synergistic cooperation of the three can produce special and significant effects.

[0102] As for the volatilization speed detection, Example 6 changes the selection of the solvent based on Example 1, so that the volatilization speed becomes faster. In actual cleaning work, it may not have sufficient contact with the residual adhesive, thereby affecting the cleaning effect. Comparative Examples 1-4 change the combination of toluene, limonene and cyclohexanone or the dosage matching effect in the system, and the matching effect between the system and 200# solvent oil becomes worse, resulting in a significant decrease in the performance of the aerosol type residual adhesive cleaning agent in all aspects.

[0103] When the residual adhesive removal effect test is performed, the operation diagram and effect diagram of the test using the aerosol type residual adhesive cleaning agent of Example 1 are referred to Figures 1-5 . Figure 1 is a preparation schematic diagram before the test. In order to facilitate the observation of the three-layer structure of the car film 1, Figure 2 the glue layer 12 is partially separated from the release film layer 11, and the aerosol type residual adhesive cleaning agent of Example 1 is sprayed uniformly against the upward glue layer 12. The aerosol type residual adhesive cleaning agent is infiltrated into the glue layer 12, and after 5 minutes, a small shovel is used to shovel the glue layer 12, so that it is gathered into a group and separated from the PVC film layer 13, which is referred to Figure 3 . In order to further facilitate the observation of the shoveling glue, it is shovelled to one place, which is referred to Figure 4 , the shovelled glue can be clearly identified, and there is no residue at the shovelled place. Refer to Figure 5 , the produced glue can be easily separated from the PVC film layer 13, and there is no residue at the removed place.
