Description

Technical Field

[0001] The present invention belongs to the field of adhesives, and in particular relates to classification number: C09J7 / 00, and more specifically, to a rat-proof adhesive film and a preparation method thereof. Background Art

[0002] As we all know, rats' teeth grow throughout their lives. To prevent their teeth from growing too long, rats often choose to grind their teeth by constantly gnawing on objects. Communication optical cables, especially the plastic protective layer of optical cables, are often eaten by rats because of their special smell. After the optical cables are eaten, the plastic protective layer on the outer layer of the optical cables is damaged, exposing the inner cable core. Once the cable core is damaged, the communication transmission function of the optical cable will be seriously affected, resulting in serious drop in communication signals, network interruption, data loss and other problems, causing significant economic losses. Therefore, preventing optical cables from being bitten by rats has become a global problem.

[0003] Patent CN117170054A discloses a rat-proof optical cable with a multi-layer rat-proof structure, which includes a physical rat-proof layer and a chemical rat-proof layer, wherein the physical rat-proof layer includes a cone-thorn layer, the cone-thorn layer includes an inner ring layer and a multi-layer tooth layer, and the sharp teeth of adjacent tooth layers are staggered, which can effectively prevent rat bites, but the structure of the physical rat-proof layer is relatively complex, which is not conducive to large-scale promotion; Patent CN109585083A discloses an anti-rat and ant protective material, and its preparation raw materials include: rubber, polyethylene, polyolefin, regenerated rubber, silane coupling agent, filler, camphor, pyrethrin, aromatic hydrocarbon sustained-release agent, etc., but the preparation raw materials of the protective material are relatively large and the cost is relatively high, which is also not conducive to large-scale promotion. Therefore, how to provide a rat-proof adhesive film with excellent rat-proof effect and relatively low preparation cost has become an industry technical problem that needs to be solved urgently. Summary of the invention

[0004] In order to solve the above technical problems, the first aspect of the present invention provides a rat-proof adhesive film, the structure of which includes: a substrate layer and an adhesive layer arranged on at least one surface of the substrate layer;

[0005] The rodent-proof adhesive film can be wound into a roll and can be partially unrolled.

[0006] The rat-proof adhesive film described in the present invention can also be processed into sheets or strips in any form, and can not only be wrapped around the adherend, but also be attached to the adherend. It is preferably used in a winding manner. After the rat-proof adhesive film is wrapped around the adhered object, the adhesive film can wrap the adhered object evenly and tightly in an environment at -40 to 170°C.

[0007] The present invention can provide excellent peeling force in the environment where the above-mentioned adhered objects are stored, and will not fall off from the adhered objects, nor cause damage or pollution to the adhered objects. The rat resistance level is not lower than FS2 (the surface of the sample protective layer has bite marks greater than 1mm, but the value should not be greater than 1 / 2 of the thickness of the outer protective layer), and preferably meets the condition of FS1 (the surface of the sample protective layer has no tooth marks or visible bite marks, and the bite depth should be less than 1mm); if the surface of the above-mentioned adhered object does not have an adhesive film with rat-proof function, the adhered object can be easily bitten and damaged by mice, and the appearance and function of the adhered object will be damaged.

[0008] The raw materials for preparing the adhesive layer include an adhesive, and the softening point of the adhesive is 50-170° C. The raw materials for preparing the adhesive include: one or more of a base polymer, a tackifying resin, a functional additive, and an odorant.

If the peel force of the rat-proof adhesive film at around 23°C is less than 0.2 N / cm, it is easy to fall off the adherend. If the peel force of the rat-proof adhesive film at around 23°C is greater than 5 N / cm, it is not easy to peel off from the adherend. The above peel force can be measured in subsequent examples.

According to the needs of the actual application scenario, the types of base polymers and tackifying resins, mass ratios, etc. can be reasonably selected to meet the coating requirements of different types of substrate layers.

[0045] Antioxidants

[0046] As one of the important components of the adhesive layer, the antioxidant has an important role in resisting the thermal oxidation aging and decomposition of the adhesive layer, although the amount of antioxidant added is not much. The antioxidant used in the adhesive mixture is characterized in that the antioxidant is a substance that can destroy free radicals or decompose active hydroperoxides, and it can be at least one of aromatic amines, hindered phenols, phosphites and thioesters.

[0061] Furthermore, the plasticizer is cyclohexane oil.

[0062] Flame retardants

[0063] The adhesive layer is added with flame retardants to improve the flame resistance of the rat-proof adhesive film material, prevent the material from being ignited and inhibit the spread of flames, which helps prevent fires and slow down the spread of fire when a fire occurs. Halogen flame retardants, phosphorus-containing flame retardants, and inorganic flame retardants can be used as flame retardants.

[0064] As a flame retardant, it can prevent the flame from continuing to burn the material by absorbing heat, covering, interrupting chain reactions, or asphyxiating the gas. It can be used alone or in combination with one or more.

[0065] As halogen flame retardants, additive flame retardants mainly include: decabromodiphenyl ether (DBDPO), tetrabromobisphenol A, octabromodiphenyl ether (OBDPO), etc.; reactive flame retardants mainly include: tetrabromobisphenol A (TBBPA), 2,4,6-tribromophenol, etc.; polymer flame retardants mainly include brominated polystyrene, brominated epoxy, tetrabromobisphenol A carbonate polymer, etc.

[0066] As phosphorus-containing flame retardants, ammonium polyphosphate, tricresyl phosphate (TCP), diphenylcresyl phosphate (CDP) and triphenyl phosphate (TPP) can be used.

[0068] The rat-proof adhesive film preferably has a flame retardant grade not lower than Grade C, and the flame retardant grade is determined based on the test method for "Combustion Characteristics of Automobile Interior Materials" specified in GB 8410-2006.

[0069] Furthermore, the functional additives include: antioxidants and / or plasticizers.

[0070] Odor-repellent

[0071] As the repellent, conventional repellents can be used, for example bittering agents, spicy agents, odorants, etc. These repellents can be used alone or in combination of two or more. From the perspective of irritation to mice, preferred are: denatonium benzoate bittering agents and / or capsaicin-type spicy substances.

[0072] As bittering agents among the repellents, benzoic acid [2-[(2,6-dimethylphenyl)amino]-N,N-diethylbenzylammonium (bitter) and o-sulfonylbenzoimide [2-[(2,6-dimethylphenyl)amino]-2-oxoethyl]-N,N-diethylbenzylammonium (bitter S) can be used. Among them, the bitterness of bitter S is about 4 times that of bitter, but bitter is highly soluble in water, while bitter S is not easily soluble in water. As the pungent agent among the repellents, trans-8-methyl-N-vanillyl-6-nonenamide (capsaicin) and its modified compounds with pungent function can be used.

[0073] Furthermore, the capsaicinoid spicy substance includes capsaicin; and the denatonium benzoate bittering agent includes bitters S.

[0074] Furthermore, the mass percentage of the repellent in the adhesive is 0.3-18%.

[0075] In order to improve the rat-repellent effect of the rat-proof adhesive film, the present invention preferably uses bitters S or capsaicin as the taste-repellent, wherein the strong bitter taste of bitters S is a very unpleasant taste for mice. When mice come into contact with the rat-proof adhesive film containing bitters S, they will choose to avoid these items due to the unbearable bitter taste. In addition, compared with some chemical rodenticides, bitters S has higher safety and will not kill mice directly, but will drive them away through bitterness, so it is relatively friendly to humans and other animals. Capsaicin can stimulate the central nervous system and peripheral nerve endings of mice, especially the capsaicin receptor (VR1). This stimulation will cause mice to have a highly nervous and fearful reaction, thereby The rat repellent effect can be achieved, and capsaicin is safe, non-toxic, natural, green and effective, and is also relatively friendly to humans and other animals. However, the amount of the repellent used needs to be further limited. When the amount of the repellent is too small, the rat repellent effect is not obvious, and when the amount of the repellent is too large, the mass proportion of the base polymer and the tackifying resin in the adhesive raw material system is relatively small, so the cohesive force of the adhesive layer is significantly reduced, and the peeling force is also increased accordingly. The rat-proof adhesive film is peeled off after use, and residual glue is likely to appear. Therefore, the present invention limits the mass percentage of the repellent in the adhesive to 0.3-18%, so as to achieve a performance balance between effective rat repellent and peeling without residual glue.

[0076] The second aspect of the present invention provides a method for preparing a rat-proof adhesive film.

[0077] The rat-proof adhesive film of the present invention can be produced by any suitable method, for example, by the following method: first preparing an adhesive, coating the adhesive on a substrate layer to form an adhesive layer; or coating the adhesive on a suitable substrate layer to form an adhesive layer, and then attaching the adhesive layer to a substrate by laminating the substrate layer, etc.

[0078] The manufacturing method of the above-mentioned rat-proof adhesive film can be achieved by any suitable coating process. For example, each layer can be achieved by coating or by UV irradiation after coating. The following can be listed as coating methods: multi-pass coating, gravure printing, extrusion coating, spraying, painting, impregnation coating, screen printing, blade coating, reverse roller coating, lip coating, etc. The processing temperature can be set to any suitable temperature while satisfying the material properties of the processing object.

[0079] As an practicable example, the method for preparing the rat-proof adhesive film comprises:

[0080] S1. Put the base polymer into a stirred tank, evacuate the tank, and heat for 20-40 minutes;

[0081] S2, then add 30-60% of the total amount of tackifying resin, evacuate, and heat for 20-40 minutes;

[0082] S3, then put the remaining tackifying resin into the stirring kettle, evacuate the vacuum, and heat for 20-40 minutes;

[0083] S4, then put the odor-repellent into the stirring kettle, evacuate the kettle, and heat for 20-40 minutes;

[0084] S5, discharging and cooling to room temperature to obtain an adhesive;

[0085] S6. Evenly apply the adhesive to one side of the substrate layer to form an adhesive layer, thereby obtaining a rat-proof adhesive film.

[0086] The rat-proof adhesive film disclosed in the present invention can be pasted or wrapped around various equipment or devices for protection purposes. For example, the rat-proof adhesive film can be used for wires and cables, ropes, pipes, leather goods, wooden products and any other items and parts thereof that have been gnawed by rats, in indoor or outdoor places where rats are present.

[0087] Beneficial Effects

[0088] (i) The raw materials of the adhesive in the present invention are selected from the base polymer and the tackifying resin, which can ensure that the adhesive layer has a high peeling force and excellent bonding performance. It can not only be attached to the adhered object in the form of a sheet, but also can be wrapped around the protected object in the form of a strip, with excellent adhesion.

[0089] (ii) Based on the different types of substrates to be bonded, the present invention can select different types of base polymers and tackifying resins for compounding, and the application range of the rat-proof adhesive film is relatively large.

[0090] (III) The present invention preferably uses bitter essence S and capsaicin as the taste retardants, which can effectively prevent mice from continuously gnawing and destroying the protected objects. It not only has excellent rodent repelling effect, but also has no effect on the life safety of humans and other creatures.

[0091] (iv) The rat-proof adhesive film prepared by the present invention not only has excellent adhesive properties, but can also be completely peeled off after use without residual adhesive, and has excellent use effect.

[0092] (V) The raw materials for preparing the rat-proof adhesive film provided by the present invention are from a wide range of sources and have a low cost. In addition, the structure of the rat-proof adhesive film is simple and is expected to be market-oriented and applied. BRIEF DESCRIPTION OF THE DRAWINGS

[0249] Performance Testing

[0250] 1. Peel force test

[0251] The rat-proof adhesive films in Examples 1-9 and Comparative Examples 1-4 were made into samples with a length of 150 mm and a width of 25 mm. A SUS430 steel plate cleaned with toluene and anhydrous ethanol was used as a test laminate. The sample was laminated on the 430 steel plate in a standard environment of 23°C and 50% RH (humidity). An automatic roller press was used with a rolling speed of 600±30 mm / min and a 2 kg rubber roller was rolled back and forth 2 times to press the sample on the 430 steel plate. After the sample was prepared, it was necessary to test it within 1 minute. According to the provisions of ISO 29862, a universal material testing machine (Kejian tensile machine) was used to peel it at a tensile speed of 300 m / min and a peeling angle of 180°. Three samples were tested in each group, and the arithmetic mean of the three data results was taken as the result; unit: N / cm.

[0252] The experimental test results are recorded in Table 3.

[0253] 2. Residual adhesive test

[0254] The rat-proof adhesive films in Examples 1-9 and Comparative Examples 1-4 were made into samples with a length of 150 mm and a width of 25 mm. A SUS430 steel plate cleaned with toluene and anhydrous ethanol was used as a test laminate. The sample was laminated on the 430 steel plate in a standard environment of 23°C and 50% RH. An automatic roller press was used with a rolling speed of 600±30 mm / min and a 2 kg rubber roller was rolled back and forth 2 times to press the sample on the 430 steel plate. After the sample was prepared, it was necessary to test it within 1 minute. According to ISO 29862, a universal material testing machine (Kejian tensile machine) was used to peel it at a tensile speed of 300 m / min and a peeling angle of 180°. Three samples were tested in each group, and the surface of the 430 steel plate after peeling was observed.

[0255] ○: No residual glue under 100x optical microscope observation.

[0256] ×: There is residual adhesive when observed under a 100x optical microscope.

[0257] The experimental test results are recorded in Table 3.

[0258] 3. Rodent-proof level test

[0259] The rat-proof adhesive film was made into a strip with a width of 25 mm and a length of 700 mm. The strip was wound with 12 0.5 mm 2 The cable should be tightly wound and bundled. The tape should be applied to the test sample from the bottom, and each circle of tape should overlap the width of the previous tape by half, making a 300mm long wire harness to be tested. The two ends are fixed with iron wire. The wound structure is as follows: Figure 3 shown.

[0260] Refer to JB / T 10696.10 Test methods for mechanical and physical and chemical properties of wires and cables Part 10: Rat gnawing test, and test the samples for 14 consecutive days. Feed SD (Sprague Dawley) rats normally every day, observe the rat activities, diet and sample gnawing conditions, and make a description record of the sample surface, and assess the protection level according to Table 2 below.

[0261] Table 2 Evaluation of the protection level of rat-proof adhesive film to rats

[0262]

[0263] The experimental test results are recorded in Table 3.

[0264] Table 3

[0265]

[0266]

[0267] As can be seen from Table 3, Examples 1 to 9 have excellent protection levels. After the objects are adhered or wrapped with the rat-proof adhesive film, the adhered objects can be significantly protected from being damaged by the gnawing of outdoor SD rats. In addition, the rat-proof adhesive film has excellent peelability, not only having good adhesion but also being able to be peeled off after use without leaving residual adhesive pollution on the adhered objects.

[0268] In Comparative Examples 1 to 4, as shown in Table 3, due to the low content of the anorectant in Comparative Examples 1 and 3, the protective effect against rats' gnawing cannot be achieved, resulting in the wires being damaged by rats' gnawing and exposing the metal wires. In Comparative Example 2, since no tackifying resin is included, the peeling force is low and the adhesive cannot be closely attached to the adhered object, resulting in unsatisfactory protective effect. In Comparative Example 4, the glue cohesion is poor and it is not easy to peel off after use, resulting in residual glue pollution after peeling, and the requirement of no residual glue after peeling cannot be met.
