Abstract
Description
Technical Field
[0001] This invention relates to the field of adhesive chemical technology, and in particular to a liquid adhesive with ultra-low viscosity and high solid content and its preparation method. Background Technology
[0002] As digital products become smaller and more precise, the requirements for structural stability and electrical safety of their internal components (such as chips, bearings, connectors, etc.) have increased significantly.
[0003] Liquid adhesives, as key auxiliary materials, are expected to meet the requirements of low viscosity and insulation in this field. "Low viscosity" means that the low-viscosity liquid adhesive can penetrate into the gaps between tightly bonded metal or electronic components through a pressure-fitting process, forming a strong bond after curing in an airless environment, effectively preventing loosening or leakage of components due to impact or vibration. "Insulation" means that digital product components (such as motherboard chips and solder joints) must avoid short circuits or signal interference. Insulating liquid adhesives fill the gaps between components, forming a physical isolation layer that can shield against electromagnetic interference and prevent electrical faults caused by moisture and dust intrusion.
[0004] Nowadays, liquid adhesives on the market generally pursue high solid content. However, high solid content adhesives have the problem of difficult stirring due to the high consistency of the system during the production process. This will cause the temperature to rise and the distribution of various media in the adhesive to be uneven, which will affect the product's strength and other properties. Improper stirring process will greatly reduce the success rate of adhesive preparation. Summary of the Invention

Using a pre-trained adaptive dilution model, a pre-constructed second part of vinyl silicone oil was used to adaptively dilute the compound to obtain the base rubber. A first portion and a second portion of the base adhesive are obtained from the base adhesive, wherein the first portion and the second portion of the base adhesive have the same mass.

The first A-gel mixing intermediate was stirred at 40 Hz for 30 minutes to obtain the second A-gel mixing intermediate. The A glue preparation container is vacuumed. The second A-glue intermediate, which is in a vacuum environment, is stirred at a speed of 40 Hz for 20 minutes to obtain A-glue.
[0010] Optionally, the step of filling the A and B adhesives with equal volumes to obtain a liquid adhesive product includes: According to the preset filling flow rate, obtain a rated amount of glue A, and according to the filling flow rate, obtain a rated amount of glue B; The rated amount of glue A is sieved to obtain glue A to be packaged, and the rated amount of glue B is sieved to obtain glue B to be packaged. The two adhesives, A and B, to be packaged are isolated and sealed to obtain a liquid adhesive product.
[0011] Optionally, before obtaining the first and second portions of base adhesive from the base adhesive, the method further includes: Obtain the viscosity of the base adhesive; Determine whether the viscosity is within a preset acceptable range; When the viscosity is not within the acceptable range, the base adhesive is determined to be unqualified, and unqualified base adhesive is obtained. The unqualified base adhesive is then transported to a pre-constructed raw material processing device for separation to obtain a raw material set.
[0012] Optionally, the step of transporting the substandard base adhesive to a pre-constructed raw material processing device for separation to obtain a raw material set includes: Using the pre-constructed solid-liquid separation device in the raw material processing equipment, the unqualified base adhesive is centrifuged to obtain fumed silica and the remaining mixed liquid; According to a preset set of boiling points, the remaining mixed liquid is subjected to a temperature gradient distillation operation to obtain hexamethylsilazane, dimethyldiethoxysilane and vinyl silicone oil; The fumed silica, hexamethylsilazane, dimethyldiethoxysilane and vinyl silicone oil are used as raw materials.
[0013] To achieve the above objectives, the present invention also provides a liquid adhesive with ultra-low viscosity and high solids content, produced by the method for preparing the liquid adhesive with ultra-low viscosity and high solids content. When the liquid adhesive is confirmed for use, adhesive A and adhesive B are mixed in a 1:1 ratio according to the pre-constructed usage volume to obtain the liquid adhesive. If it is confirmed that the liquid adhesive will not be used, adhesive A and adhesive B are stored based on a pre-constructed storage state, wherein adhesive A and adhesive B are stored independently, and both adhesive A and adhesive B contain a base adhesive. The base adhesive is composed of the first part of vinyl silicone oil, the first additive, and the second part of vinyl silicone oil; The first additive includes fumed silica, hexamethylsilazane, dimethyldiethoxysilane, and water; The A adhesive is composed of the first part of base adhesive, the first part of dimethyl silicone oil and the second additive, and the B adhesive is composed of the second part of base adhesive, the second part of dimethyl silicone oil and the third additive; The second additive includes a platinum catalyst; The third auxiliary agent includes hydrogen-containing silicone oil and ethynylcyclohexanol.

[0016] To address the problems described in the background art, this invention first constructs a compound using vinyl silicone oil, then dilutes the compound with more vinyl silicone oil to reduce water addition, resulting in a base adhesive with high insulation and high solids content. Next, this invention produces adhesive A and adhesive B based on this base adhesive. Both adhesive A and adhesive B contain dimethyl silicone oil, which effectively reduces their viscosity, allowing the adhesives to penetrate deeper into crevices and increasing the contact area. Furthermore, when the platinum catalyst added to adhesive A and the hydrogen-containing silicone oil added to adhesive B interact, they rapidly catalyze a cross-linking and curing reaction, quickly completing the bonding process. Therefore, this invention reduces the viscosity of high-solids-content liquid adhesives and improves their mixing efficiency. Attached Figure Description

Using a pre-constructed viscosity sensor, the viscosity change sequence of the first vinyl silicone oil is obtained, and the rate of change of the viscosity change sequence is identified to obtain the viscosity change rate; When the viscosity change rate is less than the preset stirring viscosity interference threshold, it is determined that the first auxiliary agent has been incorporated into the first part of vinyl silicone oil; When the first auxiliary agent is incorporated into the first part of vinyl silicone oil, the steps described above for sequentially extracting one part of the first auxiliary agent from the set of first auxiliary agents are returned until the set of first auxiliary agents is incorporated into the first part of vinyl silicone oil to obtain the base micelle.

Then, one part of the sub-first additive is extracted from the sub-first additive set and added to the 1000 viscosity vinyl silicone oil, and stirred.

Using a pre-trained adaptive dilution model, the material supply pipeline is controlled to obtain a preset initial experimental value of vinyl silicone oil from the second portion of vinyl silicone oil, thus obtaining an experimental amount of silicone oil, and the experimental amount of silicone oil is then delivered to the adhesive preparation tank. In the glue preparation tank, the first compound was vacuum stirred for 5 minutes using the experimental amount of silicone oil to obtain a compound intermediate. During the vacuum stirring of the first compound for 5 minutes, the dilution viscosity change curve of the first compound was obtained. According to the preset dilution adjustment rules in the adaptive dilution model, the initial experimental value is updated to obtain the updated experimental value. The material supply pipeline is controlled to obtain the vinyl silicone oil with the updated experimental value from the second part of vinyl silicone oil to obtain the updated amount of silicone oil, and the updated amount of silicone oil is transported to the glue preparation tank. Using the adaptive dilution model, the effective stirring time of the updated silicone oil is predicted based on the dilution viscosity change curve; In the glue preparation tank, the compound intermediate is subjected to vacuum stirring based on the effective stirring time using the updated amount of silicone oil to obtain an updated compound intermediate, and the updated compound intermediate is used to replace the original compound intermediate. Determine whether the second portion of vinyl silicone oil has been used in its entirety; If the second portion of vinyl silicone oil is not completely used, return to the steps described above for adjusting the dilution amount according to the preset dilution rules in the adaptive dilution model; If the second portion of vinyl silicone oil is used entirely, the updated compound intermediate will be recognized as the base rubber.

[0058] The step of updating the initial experimental value according to the preset dilution adjustment rules refers to gradually increasing the updated experimental value during the dilution process according to the dilution adjustment rules of 5%, 10%, 20%, 30%, and 35%. For example, the first dilution uses 5% by mass, and the second dilution requires 10% by mass. The updated experimental value refers to the adjusted initial experimental value.

[0060] The phrase "using the updated compound intermediate to replace the compound intermediate" means that in subsequent processes, the compound intermediate will be diluted again based on the updated compound intermediate, rather than being diluted based on the compound intermediate itself.
[0061] Preferably, in this embodiment of the invention, the following batch dilution process configured according to the adaptive dilution model can yield a base adhesive with a relatively uniform dilution effect: Using 5% by mass of 1000 viscosity vinyl silicone oil from the second part of vinyl silicone oil, the compound was vacuum stirred for 10 minutes to obtain the first intermediate. Using 10% by mass of 1000 viscosity vinyl silicone oil from the second part of vinyl silicone oil, the first intermediate was vacuum stirred for 10 minutes to obtain the second intermediate; Using 20% by mass of 1000 viscosity vinyl silicone oil from the second part of vinyl silicone oil and a release agent, the second intermediate was vacuum stirred for 10 minutes to obtain the third intermediate; Using 30% by mass of 1000 viscosity vinyl silicone oil from the second portion of vinyl silicone oil, the third intermediate was vacuum stirred for 10 minutes to obtain the fourth intermediate; Using the remaining 1000 viscosity vinyl silicone oil in the second portion, the fourth intermediate was vacuum-stirred for 30 minutes to obtain the base gel.
[0062] The first intermediate refers to the rubber compound after the first vacuum mixing (dilution). Similarly, the second, third, and fourth intermediates are the rubber compounds after the second, third, and fourth dilutions, respectively.
[0063] In this embodiment of the invention, heating is first turned off, and the compound is cooled to a preset temperature of 30 degrees Celsius using a temperature control device. Then, 5% by mass of 1000 viscosity vinyl silicone oil is vacuum-stirred for 10 minutes to obtain a first intermediate. Next, 10% by mass of 1000 viscosity vinyl silicone oil is vacuum-stirred for another 10 minutes. Then, 20% by mass of 1000 viscosity vinyl silicone oil is vacuum-stirred for 10 minutes. Considering that the mixer and the compound may stick together at this point, a release agent is added at this stage; the specific amount is not limited. This yields a third intermediate. Then, 30% by mass of 1000 viscosity vinyl silicone oil is vacuum-stirred again for 10 minutes to obtain a fourth intermediate. Finally, the remaining 1000 viscosity vinyl silicone oil is vacuum-stirred for 30 minutes to obtain the base compound.

Based on the initial dilution vector, the initial stirring time vector, the characteristic set of the diluted compound, and the characteristic set of the dilution solvent, the dilution viscosity change of the experimental amount of silicone oil on the first compound is predicted, and a dilution viscosity prediction curve is obtained. The dilution viscosity prediction curve is subjected to curve feature extraction to obtain a predicted dilution feature set, and the dilution viscosity change curve is subjected to curve feature extraction to obtain a true dilution feature set. The distinguishing features between the predicted dilution feature set and the true dilution feature set are identified to obtain a distinguishing feature set. Compound feature identification is performed on the rubber compound intermediate to obtain an updated set of diluted compound features. The updated experimental values are then quantified to obtain an updated dilution vector. Based on the updated set of features of diluted compounds, the set of features of diluents, the updated dilution amount vector and the distinguishing feature set, the dilution viscosity change curve of the updated amount of silicone oil on the compound intermediate is predicted, and the predicted viscosity change curve of the second dilution is obtained. The effective stirring time is obtained by extracting the effective stirring time from the predicted viscosity change curve of the re-dilution.

[0070] The process of "predicting the change in dilution viscosity of the first compound by the experimental amount of silicone oil based on the initial dilution vector, the initial stirring time vector, the characteristic set of the diluted compound, and the characteristic set of the dilution solvent, and obtaining the dilution viscosity prediction curve" refers to the first execution process of the adaptive dilution model. Since the initial dilution vector is a percentage value, the calculation result of the dilution viscosity prediction curve is not very accurate and needs to be adjusted according to the actual measured dilution viscosity change curve to improve the accuracy of subsequent dilution viscosity prediction.
[0071] The dilution viscosity prediction curve refers to the viscosity prediction result of the adaptive dilution model for the dilution parameters of "updated experimental value of 5%" and "initial stirring time vector of 5 minutes".

This time, it has a distinguishing feature set, which can improve the accuracy of dilution viscosity prediction.
[0077] The predicted viscosity change curve for further dilution refers to the viscosity change curve during the process of diluting the intermediate compound with a new amount of silicone oil.
[0078] The operation of extracting the effective stirring time refers to taking the time point corresponding to the lowest viscosity point in the predicted viscosity change curve after further dilution as the effective stirring time.
[0079] Specifically, in this embodiment of the invention, an adaptive dilution model is used to identify the compound features of the rubber compound and the second portion of vinyl silicone oil, respectively obtaining the feature set of the diluted compound and the feature set of the dilution solvent. Then, the adaptive dilution model is used to quantify the initial experimental value and the 5-minute stirring time to obtain dilution parameters of the initial dilution amount vector and the initial stirring time vector. Then, the dilution viscosity change during the dilution of the first rubber compound using the experimental amount of silicone oil under these dilution parameters is predicted to obtain a dilution viscosity prediction curve.
[0080] Previously, this invention had actually measured the real dilution viscosity change curve using a viscosity sensor. Therefore, based on the trend between the dilution viscosity prediction curve and the dilution viscosity change curve, the adaptive dilution model can be modified for different application scenarios to improve the accuracy of subsequent prediction processes.
[0081] Specifically, the present invention sequentially performs curve feature extraction operations on the dilution viscosity prediction curve and the dilution viscosity change curve to obtain the predicted dilution feature set and the true dilution feature set, respectively. Then, a neural network is used to perform distinguishable feature recognition to obtain the distinguishable feature set.
[0082] Specifically, the present invention will next dilute the rubber compound intermediate. Therefore, the present invention will perform compound feature identification on the rubber compound intermediate to obtain an updated set of diluted compound features. Furthermore, due to the dilution adjustment rules, the amount of diluent in this dilution process also changes. Therefore, the updated experimental value is quantified to obtain an updated dilution vector.
[0083] Specifically, after obtaining the above data, the present invention can predict the dilution viscosity change curve of the updated amount of silicone oil on the compound intermediate based on the updated diluted compound feature set, dilution solvent feature set, updated dilution amount vector and distinguishing feature set, and obtain the re-dilution predicted viscosity change curve. At this time, the re-dilution predicted viscosity change curve can accurately represent the viscosity change law with time during this dilution stirring process. Therefore, the effective stirring time can be extracted from the re-dilution predicted viscosity change curve to obtain the effective stirring time.

The unqualified base adhesive is then transported to the pre-constructed raw material processing equipment for separation to obtain a raw material set.
[0089] The viscosity mentioned here refers to the physical property that measures the resistance of a fluid or semi-fluid substance (liquid adhesive) to flow, and is measured in centipoise. This invention can utilize the dynamic viscosity method for measurement, which will not be elaborated upon here.
[0090] The qualified range is configured as 1000~8000 centipoise.

The fumed silica is solid, while the rest are liquid. Therefore, the fumed silica is directly filtered using a solid-liquid separation device to obtain the remaining mixed liquid. Then, considering that the hexamethylsilazane, dimethyldiethoxysilane, and vinyl silicone oil in the remaining mixed liquid have different boiling points, the hexamethylsilazane is extracted by distillation at 126 degrees Celsius, the dimethyldiethoxysilane is extracted by distillation at 165 degrees Celsius, and the high-boiling-point vinyl silicone oil is extracted by distillation at 200 degrees Celsius to obtain the raw material set.

[0100] S4. The first portion of base adhesive, the pre-constructed first portion of dimethyl silicone oil, and the pre-constructed second additive are stirred according to a preset stirring strategy to obtain adhesive A.
[0101] The A-adhesive stirring paddle refers to the device in the A-adhesive preparation tank responsible for stirring the A-adhesive. Similarly, the B-adhesive stirring paddle is the device in the A-adhesive preparation tank responsible for stirring the B-adhesive.
[0102] The stirring strategy refers to stirring in stages at different speeds, followed by stirring under vacuum. Adhesive A is a component of the liquid adhesive product of this invention, and the same applies to adhesive B.
[0103] In detail, in this embodiment of the invention, the A-adhesive is prepared by using a pre-constructed A-adhesive stirring paddle in the A-adhesive preparation tank to stir the first part of the base adhesive, the first part of the dimethyl silicone oil, and the second additive according to a preset stirring strategy to obtain A-adhesive, comprising: Add the first part of dimethyl silicone oil and the second additive to the first part of the base glue in the A glue preparation tank to obtain the A glue raw material; Using the pre-constructed A-glue stirring paddle in the A-glue preparation tank, the A-glue raw material is stirred at a speed of 10~15Hz for 5 minutes to obtain the first A-glue stirring intermediate; Using the A-type glue stirring paddle, the first A-type glue stirring intermediate is stirred at a speed of 40 Hz for 30 minutes to obtain the second A-type glue stirring intermediate. The A glue preparation container is evacuated using a pre-built vacuum device. Using the A-glue stirring paddle, the second A-glue stirring intermediate under vacuum is stirred at a speed of 40 Hz for 20 minutes to obtain A-glue solution.
[0104] The first part of dimethyl silicone oil is prepared in the form of 2250 parts by weight.

[0111] The main function of the platinum catalyst is to catalyze the crosslinking reaction. As the core component for curing liquid adhesive, it can efficiently promote the hydrosilylation reaction between polymers containing vinyl groups (such as 1000 viscosity vinyl silicone oil) and compounds containing hydrogen groups (such as hydrogen silicone oil), thereby realizing the transformation of the adhesive from liquid to solid state.
[0112] S5. The second base adhesive, the pre-constructed second dimethyl silicone oil, and the pre-constructed third additive are stirred according to the stirring strategy to obtain adhesive B.
[0113] Specifically, in this embodiment of the invention, the second part of dimethyl silicone oil required for producing adhesive B is prepared in the form of 1908 parts by weight. Then, the third auxiliary agent is prepared in the form of 360 parts by weight of hydrogen-containing silicone oil and 4.5 parts by weight of ethynylcyclohexanol.
[0114] The hydrogen-containing silicone oil reacts with the aforementioned platinum catalyst, causing the liquid adhesive to cure rapidly. The ethynylcyclohexanol acts as an inhibitor, ensuring that the hydrogen-containing silicone oil in adhesive B does not spontaneously react with the second base adhesive.
[0115] Specifically, in this embodiment of the invention, the staged stirring process of glue B is the same as that of glue A, and will not be described in detail here.
[0116] According to the above process, the present invention can obtain glue B.

[0120] The liquid adhesive product refers to the combination of adhesive product A and adhesive product B.
[0121] In detail, in this embodiment of the invention, the step of using a pre-constructed flow controller to perform equal-volume isolation filling of adhesive A and adhesive B to obtain a liquid adhesive product includes: Using a pre-built flow controller, a rated amount of glue A is obtained from the glue A preparation tank according to a preset filling flow rate, and a rated amount of glue B is obtained from the glue B preparation tank according to the filling flow rate. The rated quantity of glue A is sieved using the first filter screen in the flow controller to obtain glue A to be packaged, and the rated quantity of glue B is sieved using the second filter screen in the flow controller to obtain glue B to be packaged. Both the first filter screen and the second filter screen are 300 mesh filters. Using a pre-built packaging machine, the A glue and B glue to be packaged are isolated and sealed to obtain a liquid glue product.
[0122] The filling flow rate is related to the size of the packaging can and can be adjusted according to the production speed required in the actual scenario.
[0123] The rated quantity of glue A refers to the amount of glue A produced per unit time at the specified filling flow rate. The rated quantity of glue B is similar and will not be elaborated further.
[0124] Both the first and subsequent second filters are 300-mesh filters, but they serve different purposes. The first filter filters adhesive A, and the second filter filters adhesive A to prevent impurities from appearing in the product. A 300-mesh filter refers to a filter with 300 openings per inch.
[0125] The packaging machine refers to equipment that seals products.
[0126] Specifically, in the embodiments of the present invention, during the production process of liquid adhesive, the output speed of adhesive A and adhesive B is controlled by a flow controller, and adhesive A and adhesive B are filtered by a first filter and a second filter respectively to ensure product quality. Finally, the adhesive A and adhesive B to be packaged are sealed into pre-produced packaging cans by a packaging machine to obtain the liquid adhesive product.
[0127] To address the problems described in the background art, this invention first constructs a compound using vinyl silicone oil, then dilutes the compound with more vinyl silicone oil to reduce water addition, resulting in a base adhesive with high insulation and high solids content. Next, this invention produces adhesive A and adhesive B based on this base adhesive. Both adhesive A and adhesive B contain dimethyl silicone oil, which effectively reduces their viscosity, allowing the adhesives to penetrate deeper into crevices and increasing the contact area. Furthermore, when the platinum catalyst added to adhesive A and the hydrogen-containing silicone oil added to adhesive B interact, they rapidly catalyze a cross-linking and curing reaction, quickly completing the bonding process. Therefore, this invention reduces the viscosity of high-solids-content liquid adhesives and improves their mixing efficiency.
[0128] An embodiment of the present invention provides a liquid adhesive prepared from a liquid adhesive with ultra-low viscosity and high solid content. When the liquid adhesive is confirmed for use, adhesive A and adhesive B are mixed in a 1:1 ratio according to the pre-constructed usage volume to obtain the liquid adhesive. If it is confirmed that the liquid adhesive will not be used, adhesive A and adhesive B are stored based on a pre-constructed storage state, wherein adhesive A and adhesive B are stored independently, and both adhesive A and adhesive B contain a base adhesive. The base adhesive is composed of the first part of vinyl silicone oil, the first additive, and the second part of vinyl silicone oil; The first additive includes fumed silica, hexamethylsilazane, dimethyldiethoxysilane, and water; The A adhesive is composed of the first part of base adhesive, the first part of dimethyl silicone oil and the second additive, and the B adhesive is composed of the second part of base adhesive, the second part of dimethyl silicone oil and the third additive; The second additive includes a platinum catalyst; The third auxiliary agent includes hydrogen-containing silicone oil and ethynylcyclohexanol.
[0129] Specifically, in this embodiment of the invention, 1000 viscosity vinyl silicone oil is used as the base adhesive, and then a second 1000 viscosity vinyl silicone oil is used as a diluent, which greatly reduces the conductivity of the base adhesive and increases its solid content. Then, dimethyl silicone oil is added to adhesives A and B respectively to reduce their respective viscosity. Subsequently, a platinum catalyst is added to adhesive A, and hydrogen-containing silicone oil and ethynylcyclohexanol are added to adhesive B.
[0130] In this embodiment of the invention, when only A-type adhesive is used, the curing reaction cannot occur without hydrogen-containing silicone oil. When only B-type adhesive is used, the lack of platinum catalyst allows ethynylcyclohexanol to effectively inhibit the curing reaction of B-type adhesive, resulting in both A-type and B-type adhesives having good stability and being able to cure quickly when A-type and B-type adhesives are used simultaneously.
