Description
Technical Field
The invention relates to the technical field of lubricants, in particular to a container lubricant for a conveyer belt and a preparation method and application thereof.
Background
In the finished product packaging operation after filling of commercial containers, the containers are typically moved by a conveyor system at very high speeds, the conveyance being effected by movement of a chain flight of conveyor belts, the speed of which is evolving from 1 to 7-8 thousand bottles/hour with efficiency requirements. In order to ensure that the container is stable during movement, the chain plate needs to be lubricated. Conveyor lubricants require that the optimum value of friction between the packaging container and the conveyor surface be dataized, expressed in terms of coefficient of friction, slip force, slip value, frictional resistance or the like. The purpose of the lubricant composition synthesis and dispensing in the prior art patents is to create the lowest possible coefficient of friction between the packaging container and the conveyor belt surface. In practice, this does not facilitate efficient transmission. During the actual execution of the conveyor belt lubrication program, the lowest possible coefficient of friction between the conveyed container and the conveyor belt surface is not necessarily advantageous for transport. The application of lubricant compositions between the container and the conveyor belt surface with too high or too low a coefficient of friction can lead to reduced system efficiency up to or including complete inability to transport the packaging container. In packaging containers having a height to width ratio much greater than 1, such as beverage bottles, the lack of adequate lubrication and unacceptably low coefficient of friction may result in excessive bottle tipping or tipping, difficulty in properly accessing the packaging section, and impact production efficiency. It is preferable to maintain the friction coefficient within a normal range. The friction coefficient of the lubricant is only about 0.25 at 1 ten thousand bottles/hour, and the friction coefficient of the lubricant is about 0.05 to 0.1 at 7 to 8 ten thousand bottles/hour.
To meet this demand, new technology for lubricants is increasingly being used. Conveyor belt lubricants are continually being developed in an effort to meet the growing demands of the industry. In particular, conveyor lubricants must meet the criteria for (1) PET (polyethylene terephthalate) compatibility, and for lubricants with higher alkalinity, PET bottles are prone to stress cracking. Since the lubricant adhered to the bottom of the container becomes high in alkalinity after drying, the polymer is broken by strong alkalinity, and thus is cracked. The total alkalinity of the lubricant composition is suitably less than about 100ppm CaCO 3 Preferably less than about 50ppm CaCO 3 Preferably less than about 30ppm CaCO 3 Equivalent; (2) the environment surrounding the conveyor belt pipeline; (3) cost of lubricant and lubricant dispensing system equipment.
Conveyor belt lubricants fall into two modes, wet lubricants and dry lubricants. By wet lubricant is meant that the conveyor belt forms a diluted aqueous lubricant solution by diluting the concentrated lubricant composition with water (i.e., a dilution ratio of 1:50 to 1:1000), and a large amount of the diluted aqueous lubricant solution is delivered to the spray nozzles by means of the proportional dilution pump and sprayed onto the link plate by means of the spray nozzles. By dry lubricant is meant that the lubricant is supplied undiluted to the nozzle by a pumping device and sprayed onto the link plate by the nozzle. These lubricant compositions can reduce damage to containers or labels from high speed conveyor belt operation.
Since the wet lubricant requires a large amount of water, the amount of water discharged to the sewage treatment system is large; in use, it is inevitable that liquid is sprayed around the conveyor belt environment. As such, diluting the lubricant with large amounts of water results in wasted resources, is environmentally unfriendly and expensive. The presence of a moist surface and still water provides a medium for the growth of microorganisms including bacteria, yeasts and molds, etc. Ponding caused by excessive lubricant solution on the floor can easily cause people to slip. The water used to dilute the concentrated lubricant solution may in turn cause stress cracking of the (PET) bottle. In addition to the high cost, environmental impact, the risks associated with wet surfaces, and the risk of container stress cracking, wet lubricants have many adverse effects in this regard of use.
While better dry lubricants, which have no adverse effect on the conveyor belt environment, are cost effective in composition and compatible with PET materials. Dry lubricants appear to meet some growing requirements.
The compatibility of the lubricant composition with PET bottles is important. However, little prior art has been able to determine PET bottle compatibility based entirely on bottle breakage (bottle failure). It is important for PET bottle compatibility that beverage bottles filled with soft drinks and exposed to conveyor lubricant solutions do not show breakage when stored. Rupture means that the filled bottle breaks or leaks and the contents flow out of the bottle. An important measure of PET compatibility of lubricant formulations is the relative failure rate of the bottles exposed to the lubricant. In the prior art, there is no positive conclusion regarding the correlation of the appearance of a bottle with the breakage rate of the bottle. Among all beverages, carbonated beverage bottles are most prone to stress cracking, with the highest requirement for compatibility of the lubricant composition with PET bottles.
There are many ways of applying dry lubricants in actual use. In brief, there are two general ways of applying the lubricant to the conveyor belt, one is spraying the lubricant in mist form onto the conveyor belt through a nozzle, and the other is using a brush to transfer the lubricant to the conveyor belt through contact of the brush with the link plate. In view of cost and loss considerations, the pump is intermittently turned on, typically for 10 seconds, and stopped for 30 to 60 minutes. Too short a pump on time and too long an interval to spray lubricant composition, the lubrication between the conveyor belt and the containers being transported on the conveyor belt may be insufficient. Too much lubricant composition is sprayed for too long a pump on time and too short an interval, again leading to lubricant loss and increased costs. The prior art methods have only sought to minimize the amount of lubricant composition used, however, none of the various modes of application and compositions of lubricant solve a problem, the dry lubricant (including some other so-called semi-dry or semi-wet) is applied to the belt flights in very small amounts, long application intervals, the moisture in the lubricant volatilizes, and the flights are prevented from being in an extremely "dry" state, i.e., the flight surfaces appear dry, which is probably one of the sources of dry lubricant names. During the operation of the conveyor belt, the lubricating film of the upper sections of the link plates is inevitably destroyed, so that the lubrication of the link plates at these positions is in failure, and the link plates are worn out severely without lubrication although the efficiency of the whole system is not reduced. Since the link plate is in a "dry" state, the damage of the lubricating film is not observable, and the application adjustment cannot be performed by observation. In reality, after such a long-term operation of the conveyor belt, the conveyor belt may break.

As a further preferred aspect of the present invention, the polyethylene glycol is a low molecular weight polyethylene glycol having a molecular weight of less than 600, preferably polyethylene glycol 200.
As a further preferred mode of the technical scheme of the invention, the bacteriostat is selected from one or more of quaternary ammonium salts, isothiazolinones, glyceryl monocaprylate, benzoate esters and glutaraldehyde esters, wherein the benzoate esters are selected from one or two of butyl parahydroxybenzoate and methyl parahydroxybenzoate; further preferably, the bacteriostatic agent is selected from one or two of quaternary ammonium salts and isothiazolinones.

in a third aspect, the invention claims the use of a container lubricant for a conveyor as described above in a container conveyor system; in specific application, the application mode of the lubricant can be performed by referring to the application mode of the existing dry lubricant, for example, the lubricant can be sent to a nozzle through a pumping device and then sprayed onto a conveying belt through the nozzle, or the lubricant can be conveyed onto the conveying belt through the contact of the brush and a chain plate by using the brush; it will be appreciated that the manner of application of the lubricant is an existing well established process known to those skilled in the art and the process will not be described in detail herein.
Compared with the prior art, the invention has the following beneficial effects:
1. the lubricant provided by the invention can generate proper friction coefficient (0.09-0.11) between the container and the surface of the conveyer belt during application, has proper total alkalinity (60) and good PET compatibility, meets the necessary standard of the conveyer belt lubricant, and more importantly, the use cost is far lower than that of the prior product, so the lubricant has great significance; the lubricant provided by the invention has N value (time T of lubricant application and time T of no application 0 The ratio of (c) is much smaller than existing products, it is known from the definition of N that the smaller the N value, the less the relative time it takes to apply, indicating that the better the lubricant performance, the lower the cost of use. The N value is creatively provided by the invention and can be used as a standard for evaluating the performance of the dry lubricant.
2. The lubricating film formed by the conventional dry lubricants such as silicon emulsion is easily damaged in the running process of the conveyer belt, and the lubricant provided by the invention effectively solves the problem; the possible reason is that after the conventional dry lubricant such as silicon emulsion is applied to the conveyor belt, a lubricating film is formed on the chain plate through adsorption, the film formed by adsorption does not form chemical bonds with the chain plate, and the film is easily taken away by a container in the operation of the conveyor belt, so that the lubricating film is abraded, and the lubricant needs to be applied periodically; the applicant found that the more the silicone in the silicone emulsion type lubricant contains "active" Si-OH, the longer the interval of lubricant application, indicating that the lubricant film is less prone to "wear", which may be the phenomenon that the "active" Si-OH undergoes condensation reaction with the plastic link plate under some unknown conditions, the effect of the chemical bond causes the lubricant film to be less prone to be carried away by the container, and the retention time is prolonged; the octamethyl cyclotetrasiloxane (D4) in the lubricant composition of the present invention contains a large amount of "active" Si-OH, and is more reactive with plastic conveyor belts than other Si-OH, thereby making the performance of the lubricant composition far superior to that of the existing products.
3. Furthermore, the alcohol ether humectant is added into the lubricant composition, so that the state that the conveyer belt is in a dry state in the existing dry film lubricant application interval is changed, the lubricating film is observable, the application interval can be adjusted in time, and the service time of the conveyer belt is prolonged.
4. The raw material components of the lubricant are easy to obtain, the production process is simple to operate, the time consumption is short, the production efficiency is high, the economic benefit is obvious, and the lubricant can be widely applied to industrial production.

Performance testing
The invention can be better understood by comparison tests. The lubricants of the present invention can be evaluated by coefficient of friction, basicity, compatibility of the lubricant with PET, and the ratio of time the lubricant is applied to not applied (actual in-situ test), as follows.
Coefficient of friction test
The lubricant friction coefficient measuring device of the present invention is described in patent document CN 210982181U. The frequency converter is regulated to drive the conveyer belt to run at the speed of 50-100 m/min, and the highest speed is 7-8 ten thousand bottles/hr. The lubricant is distributed on the surface of the conveying belt by using a nozzle, the tension meter is fixed on the measuring table, the beverage bottle of the measured object is placed on the conveying belt and is connected with the tension meter by using a rubber band, and the tension meter is connected with the computer by using a lead. The computer records the acting force exerted on the beverage bottle during the running process of the conveyor belt and calculates the friction coefficient. The lubricant was applied for 10 seconds, stopped for 60 minutes, repeated 3 times, and the coefficient of friction COF between the bottle and the conveyor belt was recorded at the end of the stopped application for 60 minutes after 3 times of repetition, for 1 minute.
Compatibility test of Lubricants with PET
The compatibility test of the lubricant of the present invention with PET was carried out as described in the PET stress cracking test section of patent document CN 101379173A. To a PET bottle (obtained from Baishi) filled with 557g of cooling water at 0 to 5℃were added 10.6g of baking soda and 17.1mL of a 50% aqueous solution containing citric acid. Immediately after the citric acid solution was added, the filled bottles were capped and the torque on the caps was adjusted to 16 in-lbs, then the bottles were rinsed with deionized water and stored at ambient conditions (20-25 ℃) overnight. 100 bottles thus filled with liquid were immersed in the lubricant working liquid and rotated for about 5 seconds until the joint separating the bottle body from the sidewall portion was reached. Move into a humidity chamber at 37.8 ℃ and with 85% relative humidity. The bins were checked daily and the number of failed bottles (broken) was recorded. On day 28, all test flasks were removed. The sample bottle had cracks giving a visual fine crack score to the bottle, where 0 = no apparent fine cracks, the bottle base was clear and transparent; whereas 10 = significant crazing, the bottle base was not clearly opaque.
Alkalinity test
100mL of lubricant sample is accurately measured, an MR indicator is added dropwise to the solution in the reagent to be measured, the solution is light green, the solution is titrated with 0.01M sulfuric acid until the color changes from light green to pink, and the total consumption of 0.01mol/L sulfuric acid solution volume V is recorded. Alkalinity m=v×10ppm.
Lubricant application (T) and non-application time (T) 0 ) Ratio ofTesting
In the simulation test of friction coefficient in a laboratory, a plurality of conditions inconsistent with a production field exist, and the most basic is that the chain plate of the conveying belt is uneven due to abrasion, and the conveying belt in the laboratory is a surface with good flatness; the transmission of the conveyer belt to the container makes a large number of beverage bottles pass through one point on the chain plate in each hour, and 7-8 ten thousand beverage bottles are reached in many times, and the lubricant adsorbed on the conveyer belt can be taken away by a large number of beverage bottles, so that the lubricant film is slowly worn and thinned, and the amount of the lubricant on the conveyer belt is dynamically reduced. While the laboratory test beverage bottles were fixed in number and the amount of lubricant on the conveyor belt was relatively static. Laboratory tests can only be used as reference data and cannot be used for explaining the actual use condition. Therefore, the present invention is applied to a production site, and the results of such tests can truly reflect the performance of the lubricant composition. In a specific test, two black upright posts are arranged at one end of the conveying belt, a workbench as in the patent CN210982181U is arranged on each upright post, a tension meter is fixed on the workbench, a beverage bottle to be tested is placed on the conveying belt and is connected with the tension meter through a rubber band, and the tension meter is connected with a computer through a wire. The computer records the acting force exerted on the beverage bottle during the running process of the conveyor belt and calculates the friction coefficient. The coefficient of friction was measured once after 60 minutes of application, each time for 60 seconds. When the friction coefficient is in the range of 0.05-0.15, no lubricant is applied, measurement is continued until the friction coefficient is not in the range of 0.05-0.15, and the accumulated time T is counted 0 Adjusting the non-application time of the application device to T 0 . General dry lubricant T: t (T) 0 The ratio is between 1:180 and 1:720. Adjustment T for testing 0 And (3) continuously testing to obtain a limit T: t (T) 0 Value N.
The lubricants obtained in the examples and comparative examples of the present invention were subjected to the above performance test, and the results are shown in table 1 below:
TABLE 1 evaluation of the Properties of the Lubricants obtained in the examples of the present invention and comparative examples
| Sample of | COF | M | PET compatibility | T:T 0 (N) |
| Example 1 | 0.11 | 50 | Disqualified 1 bottle, crack scoring 5 points | 1:5000 |
| Example 2 | 0.11 | 60 | Disqualified 1 bottle, crack score 6 points | 1:3500 |
| Example 3 | 0.09 | 30 | Failure 1 bottle, crack score 3 points | 1:14000 |
| Comparative example 1 | 0.13 | 80 | Failure 1 bottle, crack score 8 points | 1:700 |
| Comparative example 2 | 0.12 | 60 | Failure 1 bottle, crack score 8 points | 1:900 |
From the data in Table 1, it can be seen that the N value of the lubricant of the present invention is far smaller than that of the comparative example, and that the smaller the N value, the smaller the relative time it takes to apply, and the lower the cost of use. In practical applications, regarding T of dry film lubricant: t (T) 0 The value of N is basically stable in about 2 days when the product in the existing market is tested, and most of the N is about 1:500-1:1000. The N value of the invention can be generated only by 15 days, and the N value is far smaller than that of the existing product. The N value of the lubricant according to the invention is obtained for a long time because the reaction of Si-OH with the plastic link plate is slow and also depends on the Si-OH content in the lubricant composition according to the invention. In the composition of the invention, the Si-OH in D4 is "reactive" and reacts more readily with the plastic conveyor belt than other Si-OH, thus making its properties far exceeding those of the prior art.
It is because the present invention finds that the more "reactive" Si-OH the siloxanes in the silicone emulsion class contain, the longer the application time is. Besides meeting the necessary standard of conveyor belt lubricants, the use cost of the invention is far lower than that of the prior products, and the invention has great significance. In addition, the invention changes the dry state of the conveyer belt in the existing dry film lubricant application interval except the N value, so that the lubricant film has observability, the application interval can be adjusted in time, and the service time of the conveyer belt is prolonged.
Finally, it should be noted that: the above examples are not intended to limit the present invention in any way; modifications and improvements will readily occur to those skilled in the art upon the basis of the present invention; therefore, all changes, modifications, substitutions, combinations, and simplifications that may be made without departing from the spirit and principles of the invention are intended to be equivalent substitutes for those that are within the scope of the invention as defined by the appended claims.
