Description

Technical Field

[0001] This invention belongs to the field of adhesive materials technology, specifically relating to a reusable electrically conductive anti-adhesive tape and its preparation method. Background Technology

[0002] Electro-adhesive tape (also known as electro-release tape or electro-controlled tape) works on the principle that when a certain voltage is applied, the chemical or physical state at the adhesive interface of the tape undergoes a reversible change, leading to a sharp decrease or even complete disappearance of adhesion, thus achieving easy and non-destructive peeling. Reusable electro-adhesive tape is a type of smart responsive functional tape. Its core feature is that it achieves reversible adjustment of adhesion through the external stimulus of "electricity" (adhesion significantly decreases when electricity is applied, and adhesion recovers when electricity is removed), and it can be reused multiple times, unlike traditional disposable tapes or reusable tapes that require physical peeling. Its core technology revolves around the reversible mechanism of "electro-induced adhesion change," and it has already shown application potential in precision manufacturing, electronics, and medical fields.

[0003] Reusable electrostatically de-adhesive tape has the following key characteristics: (1) Reversible adhesion adjustment, the core advantage is "electrostatic de-adhesion and de-adhesion re-adhesion", no physical tearing is required, avoiding damage to the surface of the adhered object (such as residual adhesive residue and scratches on the substrate when peeling traditional tape); (2) Reusability, under reasonable use conditions, it can be repeatedly pasted and de-adhesive multiple times, reducing the cost of consumables, especially suitable for mass production scenarios; (3) Controllable adhesion, by adjusting the current / voltage and the energizing time, the degree of adhesion reduction can be precisely controlled to adapt to different scenario requirements; (4) Environmental protection, reducing the consumption of disposable tape, and most substrates are recyclable, which is in line with the green and low-carbon trend. In the existing technology, electrostatically de-adhesive tape releases a lot of residue after being energized, which contaminates the adhered object and makes it difficult to reuse. At the same time, there will be obvious residue on the adhered object after de-adhesion. The above-mentioned problems affect its further use.

[0004] Therefore, the question is how to screen the components of the tape, introduce suitable reversible adhesive materials, obtain an electrically conductive anti-adhesion tape that can achieve electric peeling effect while being reusable multiple times and avoiding residue. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a reusable electrically conductive anti-adhesive tape and its preparation method. The present invention uses a reversible adhesive material containing an azobenzene structure as the main component of the tape, and combines it with quantum dot-based electroluminescent ultraviolet light materials to prepare an electrically conductive anti-adhesive tape. Through the synergistic effect of the reversible adhesive material and the electroluminescent ultraviolet light material, a good electrically conductive peeling effect is obtained, and it has an excellent peel force recovery ratio, thereby enabling repeated use after multiple peelings. In addition, no adhesive residue will occur.

[0006] A first aspect of the present invention provides a method for preparing a reusable electrically conductive anti-adhesive tape, comprising the following steps: By weight, 80-100 parts of reversible adhesive material, 20-30 parts of electroluminescent ultraviolet material, 10-20 parts of terpene resin and 0.4-0.8 parts of leveling agent are added to 100-120 parts of solvent and stirred for 50-60 minutes. The mixture is then coated onto a release film, baked, laminated with a protective film, and cured to obtain a reusable electrostatically conductive non-adhesive tape.

[0007] As a preferred embodiment of the present invention, the reversible adhesive material may be in the following weight proportions: 80 parts, 85 parts, 90 parts, 95 parts, or 100 parts.

[0008] As a preferred embodiment of the present invention, the weight parts of the electroluminescent ultraviolet material may be 20 parts, 22 parts, 24 parts, 26 parts, 28 parts, or 30 parts, etc.

[0009] As a preferred embodiment of the present invention, the weight parts of the terpene resin may be 10 parts, 12 parts, 14 parts, 16 parts, 18 parts, or 20 parts, etc.

[0010] As a preferred embodiment of the present invention, the weight parts of the leveling agent may be 0.4 parts, 0.5 parts, 0.6 parts, 0.7 parts, or 0.8 parts, etc.

[0011] As a preferred embodiment of the present invention, the solvent may be in the following weight proportions: 100 parts, 105 parts, 110 parts, 115 parts, or 120 parts, etc.

[0012] As a preferred technical solution of the present invention, the preparation method of the reversible adhesive material is as follows: product A is prepared by using p-toluidine and phenol as raw materials; product A is mixed with 6-chloro-1-hexanol and subjected to a heating reaction to obtain product B; product B and acryloyl chloride are used as raw materials to prepare product C; product C is mixed with 2-cyanopropyl-2-ylbenzodisulfide and subjected to a polymerization reaction under the action of azobisisobutyronitrile (AIBN) to obtain the reversible adhesive material.

[0013] This invention uses p-toluidine and phenol as raw materials. The diazotization of p-toluidine generates a diazonium salt, which is then coupled with phenol under alkaline conditions to obtain product A containing an azobenzene structure. Under alkaline conditions, the phenolic hydroxyl group in product A is converted into a more nucleophilic phenoxy anion, which attacks the chlorine atom of 6-chloro-1-hexanol to form an ether bond, ultimately introducing product B containing a terminal hydroxyl group. The terminal hydroxyl group in product B undergoes a nucleophilic substitution reaction with the acyl chloride group of acryloyl chloride, introducing an acrylic double bond at the end of the flexible chain that can participate in free radical polymerization, providing a carbon-carbon double bond active site for subsequent polymerization reactions. Finally, using azobisisobutyronitrile as an initiator and 2-cyanopropyl-2-ylbenzodisulfide as a RAFT reagent, a reversible adhesive material containing an azobenzene structure is obtained through RAFT-controlled free radical polymerization.

[0014] As a preferred technical solution of the present invention, the preparation steps of product A are as follows: by weight, 15-20 parts of hydrochloric acid, 15-20 parts of deionized water and 100-110 parts of acetone are mixed, then 8-10 parts of p-toluidine are added and stirred evenly, 40-50 parts of sodium nitrite aqueous solution with a mass concentration of 10% are added at 0-4°C and stirred for 30-40 minutes, then 6-8 parts of phenol are added and the pH is adjusted to 9-10 and stirred for 100-120 minutes, filtered, washed with water and dried to obtain product A.

[0015] As a preferred embodiment of the present invention, the preparation steps of product B are as follows: by weight, 6-8 parts of product A and 4-6 parts of potassium carbonate are added to 35-45 parts of N,N-dimethylformamide, stirred at 28-30°C for 20-30 min, then 0.01-0.03 parts of potassium iodide and 4-6 parts of 6-chloro-1-hexanol are added, the temperature is raised to 100-110°C and reacted for 20-24 h, cooled to room temperature and transferred to an ice bath to precipitate the precipitate, filtered, and the filter residue is recrystallized to obtain product B.

[0016] As a preferred technical solution of the present invention, the preparation steps of product C are as follows: by weight, 4-6 parts of product B, 1.2-1.6 parts of triethylamine and 40-50 parts of dichloromethane are mixed evenly at 0-4°C, and then 1.4-1.8 parts of acryloyl chloride are added and stirred for 20-24 hours. The solvent is removed by rotary evaporation and purified to obtain product C.

[0017] As a preferred embodiment of the present invention, the polymerization reaction steps are as follows: by weight, 10-15 parts of product C, 0.1-0.3 parts of 2-cyanopropyl-2-ylbenzodisulfide and 0.01-0.03 parts of initiator azobisisobutyronitrile are added to 40-50 parts of anisole, and the mixture is heated to 70-80°C and reacted for 48-50 hours under an argon atmosphere. After the reaction is completed, methanol is added to precipitate the precipitate, which is then filtered, and the filter residue is dried under vacuum.

[0018] The azobenzene structure of the reversible adhesive material of this invention is the core functional unit for repeated use. Its essence is to regulate the interfacial forces of the material at the molecular conformation level through cis-trans isomerization reaction. The linear structure of trans-azobenzene is conducive to the tight adhesion between the material and the surface to be bonded. The molecular chains can be fully spread to fill the tiny bumps and depressions on the surface of the object to be bonded, and a stable bond is formed through strong intermolecular forces. The curved structure of cis-azobenzene only disrupts the "intermolecular / interfacial forces" without damaging the material's bulk structure or the surface of the object to be bonded, which can effectively avoid the formation of adhesive residue.

[0019] As a preferred embodiment of the present invention, the electroluminescent ultraviolet material is a quantum dot material; The preparation method of the quantum dot material is as follows: 4-8 parts by weight of melamine are kept at 480-500℃ for 100-120 min, cooled to room temperature, and ground to obtain a solid powder; 6-8 parts of ammonia water and 22-24 parts of deionized water are mixed, and then 0.2-0.4 parts of the solid powder are added and sonicated for 2-4 h, transferred to a reaction vessel, kept at 150-160℃ for 3-5 h, centrifuged to collect the supernatant, and freeze-dried to obtain the quantum dot material.

[0020] The electroluminescent ultraviolet material of the present invention can achieve electroluminescence effect of ultraviolet light with a specific wavelength of 350~400nm under an electric field.

[0021] As a preferred embodiment of the present invention, the leveling agent is selected from one or more of the following: leveling agent BYK358N, leveling agent BYK-333, and leveling agent BYK381.

[0022] As a preferred embodiment of the present invention, the baking conditions are: baking at 75~85℃ for 2~4 minutes.

[0023] As a preferred embodiment of the present invention, the curing conditions are: curing at 40~50℃ for 50~60 hours.

[0024] A second aspect of the present invention provides a reusable electrically conductive adhesive tape prepared by the preparation method described in the first aspect.

[0025] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention adds reversible adhesive material, electroluminescent ultraviolet light material, terpene resin and leveling agent into solvent and stirs them together. Then, it is coated on release film and successively baked, composite protective film and cured to obtain reusable electrostatic anti-adhesive tape. It has good electrostatic peeling effect, can be reused many times, and will not leave any residue.

[0026] (2) The reversible adhesive material of the present invention, combined with the electroluminescent material, can achieve a reusable electro-adhesive de-adhesion effect. During the electro-adhesive process, the electroluminescent material can emit ultraviolet light of a specific wavelength (wavelength of 350~400nm), which induces the trans azobenzene structure in the reversible adhesive material to be converted into the cis azobenzene structure, thereby achieving an electro-adhesive peeling effect. At the same time, after the applied voltage is removed and the adhesion is repeated, visible light can cause the cis azobenzene structure to be converted back into the trans azobenzene structure, thereby obtaining a good peeling force recovery ratio.

[0045] Comparative Example 1 The difference between this comparative example and Example 1 is that no 30 parts of electroluminescent ultraviolet material are added to the tape.

[0046] Comparative Example 2 The difference between this comparative example and Example 1 is that an acrylic pressure-sensitive adhesive is used instead of a reversible adhesive material.

[0047] The performance of the tapes provided in the above embodiments and comparative examples was tested using the following methods: Peel strength test: After removing the protective film from a 50μm thick tape, it was adhered to a steel plate and pressed back and forth three times with a 2kg rubber roller. The sample was then placed at 25℃ for 24 hours to obtain the sample. The peel strength before the first power-on was tested. The sample was then subjected to a 100V*5min power-on treatment, and the peel strength after the first power-on was tested.

[0048] Peel force recovery ratio test: The sample that has undergone the peel force test after being powered on is reattached to a new steel plate, pressed with a 2kg rubber roller 3 times, placed at 25℃ for 24h, and the re-attach peel force is tested. Peel force recovery ratio = re-attach peel force / peel force before first power-on × 100%.

[0049] Residual adhesive after electric stripping: Observe whether there is residual adhesive on the surface of the steel plate after the tape is stripped by electric stripping.

[0050] The performance test data above are shown in Table 1.

[0051]

[0052] As can be seen from the above, the present invention uses a reversible adhesive material containing an azobenzene structure as the main component of the tape, and combines it with zinc oxide quantum dot-based electroluminescent ultraviolet light material to prepare an electrically conductive and non-adhesive tape. Through the synergistic effect of the reversible adhesive material and the electroluminescent ultraviolet light material, a good electrically conductive peeling effect is obtained, and it has an excellent peel force recovery ratio, thereby enabling repeated use after multiple peelings. In addition, no adhesive residue will occur (Examples 1 to 3).

[0053] Compared to Example 1, the tape did not contain 30 parts of electroluminescent ultraviolet material, thus lacking the luminescence effect of the electroluminescent ultraviolet material under an electric field. As a result, the peel force increased after the first energization, the peel force recovery rate decreased, and residue appeared after peeling (Comparative Example 1). Compared to Example 1, the acrylic pressure-sensitive adhesive was used instead of the reversible adhesive material. As a result, the cis-trans isomerization change of azobenzene in the reversible adhesive material was lacking. As a result, the peel force increased after the first energization, the peel force recovery rate decreased, and residue appeared after peeling (Comparative Example 2).
