Description of the invention: [Technical field to which the invention pertains] This creation relates to an improvement of a security tape or patch that can show whether it has been torn, especially in a high temperature state, whether it can be displayed or not. Open security tape or patch. Used for various items, documents, stickers, for identification purposes. [Prior Art] Various conventional security tapes or roll-cut security patches are hereinafter referred to as security tapes, for example, the new patent number of the Republic of China: M247591, 195318, 203254, 035654, 165272--- --- Wait, although the structure of each part is different, but the principle is nothing more than the substrate, the combination of the 'color layer' mucous layer 'adhesive layer' layer and layer of the off-printing layer, using the adhesion between the layers Differently, various effects of displaying tear marks are produced, and the principles, methods and effects of the traces have been described in detail in the documents, and will not be described below. These conventional designs are feasible at normal temperature. However, in a high temperature environment, such as heating with a high temperature hot air blower, the materials of the coatings are softened by high temperature, and the coating and the substrate are more encrypted, and the viscosity is sticky. However, the adhesive layer is lowered in adhesion to the object due to the high temperature, so that the originally set track effect is lost. Conventional techniques add a hardener to the adhesive layer to increase the softening point of the adhesive, or to reduce the peeling force between the coating and the substrate, which is only better than the original effect, with the formulation of different producers. Different, the conditions of the stickers are different, different from the speed of _, although the temperature of the failure is also high, but as long as the temperature is high enough, and slowly tear from the stickers 5 200812794. All kinds of secret tapes that are known will be invalid and cannot be clearly identified for identification. For example, according to the test, the commercial products are made by Taiwan Zuoyu Industrial Co., Ltd., and the security tape designed according to the Republic of China new patent number 465454 , product number SK-8802-2, a strip of width 2 · 5 cm attached to a stainless steel test plate (AISI 304), after rolling with a roller at a pressure of 4.6 kg / cm ^ 2, will be The tape was continuously heated to 90 ° C, and the security tape was peeled off at an angle of 90 degrees, and the peeling speed was 2 cm / min. The tape lost its original trace function. SUMMARY OF THE INVENTION In order to completely solve the above-mentioned conventional security tape or security patch, which cannot be manifested at a high temperature, the present invention is in addition to the design principle and the track function of the conventional security tape tear-off mark. Further, a material with a low glass transition temperature (T/G) is used to form at least one special coating in the security tape, and the cohesive strength of the coating is responsive to changes in temperature, so that the special coating is The softening peeling temperature between the adjacent coating layers is lower than the critical temperature at which the normal temperature tearing indicates failure. When the security tape tears the security tape at a normal temperature below the softening peeling temperature, a tearing label may occur, and when the security tape reaches a high temperature above the softening peeling temperature between the special coating and the adjacent coating between the special coatings, The special coating has melted into a semi-fluid resentment before the tearing of the tracer at normal temperature, and if the tape is torn open, a significant chromatic aberration or tearing trace is left on the surface of the tape and the object to be attached. It can provide the identification effect of the 200812794 article sealing state under normal temperature and high temperature conditions. If the protective tape is not torn at this high temperature, its appearance does not change. After returning to normal temperature, the physical properties and the trace function of the security tape are restored to the normal temperature condition. [Embodiment] In order to explain the contents of the present invention in detail, the following examples are exemplified, and the structure, scientific data, and test conditions of the embodiments mentioned in the document are for the purpose of explanation and not limitation. Within the scope of the structure, data, _ or object to be attached. Any use of the technical ideas and means of this creation is still within the scope of this creation. First of all, it should be explained that because the existing definitions of scientific terms and internationally accepted experimental methods are not sufficient to fully explain some of the techniques in this creation, the following definitions of the special nouns, terms and test methods are first introduced: 1. Normal temperature display The failure critical temperature of the trace: When a certain security tape reaches a certain temperature or higher, when the security tape is removed from the sticker, the security tape cannot float the normal temperature tearing mark due to the high temperature, and the temperature is called the temperature. "Failure critical temperature T-1 of normal temperature trace" of the security tape. The test method is as follows: take a test strip with a strip width of 2·5 cm and a length of 15 cm, stick it on a stainless steel test plate (Aisi 304), and roll it with a roller at a pressure of 4 5 a kg/cm 2 . One end of the tape is clamped with the clamp of the test machine, the tape is continuously heated, and the test glue is applied under the clamp of 9 degrees, the peeling speed is 2 cm/min, and the test tape cannot be traced, 7 200812794 That is, the failure critical temperature τ-i of the test tape at room temperature. 2. Softening peeling temperature τ-2: Non-destructive transfer temperature T/G due to different test conditions. According to the test only, the transition temperature T/g may be greater than, equal to, and less than the softening stripping temperature T~2. This creation uses the security tape of the embodiment for testing. The object to be tested is a special coating and a coating to which it is attached. The rainer continues to apply the adhesive layer to the adhesive condition according to the adhesive layer conditions of the embodiment. Warm and slowly peel off the tape until the two coatings are separated, or at least one of the special coatings melts into a semi-fluid, self-stratifying due to a decrease in cohesive strength, which is called the "softening stripping temperature" of the security tape. T-2". Test method: Take a strip of test tape with a width of 2.5 cm and a length of 15 cm, attach it to a stainless steel test plate (AISI 304), and roll it tightly with a roller of 4.6 kg/cm 2 , and use one end of the tape. The fixture of the test machine was lost. 'The tape was continuously heated, and the test tape was peeled off at an angle of 9 degrees. The peeling speed was 2 cm/min until the coating of the test tape produced delamination and chromatic aberration. EXAMPLES The soft peeling temperature T-2 of the tape was tested. 3. Special coating: According to the different examples, it is one of high temperature melting layer, 2 high temperature melting color layer and 3 high temperature melting dyeing adhesive layer. 4. South Temperature: In each of the examples, the temperature range of the softening peeling temperature T-2 or more was softened. 5 · Normal temperature: In each of the examples, the temperature range of the softening peeling temperature T-2 or less. 6. Trace function at room temperature: 200812794 In the normal temperature range, the tear-off security tape appears to be torn open for identification of whether it has been torn open. 7. High-temperature trace function: In the high temperature range, the tear-off security tape shows tearing marks for identifying whether it has been torn open. First, please refer to the first figure of the creation embodiment, P-1 of the schematic diagram,

The P-1 curve indicates that the peeling force between the coating film formed by all the coating layers and the substrate changes as the temperature rises, below the tear-opening mark area of the security tape. The P-2 curve indicates that the adhesive layer of the security tape changes the adhesion of the adhesive as the temperature rises. T-1 indicates a conventional security tape design without a special coating. When the temperature reaches T-1 or higher, p-1>p-2, thus the originally set trace function is lost, usually T_1 is about 72±l. 〇°c or so ❹ In order to solve the above problem, 'this creation provides a new technology to make the implementation of this creation. For example: implementation (4) security tape at normal temperature, where the peeling force of the coating film under the tearing labeling range to the substrate is less than The adhesion of the adhesive layer to the sticker is not the peeling force of the coating film below the marking range to the substrate, and the adhesion of the adhesive layer to the adhesive. The material of the selection degree (Τ/G) is made into a special coating, and the material of the special _M transfer coating may be a mixture of two or more materials or a combination of (10) copolymer degree and interlayer adhesion to temperature.

Between the special coating and the coating it is in contact with The softening is lower than the failure critical temperature τ 1 of the normal temperature trace. According to the experiment, the temperature of the 胶带 2 of the security tape is 4 〇. 〇~9 〇. The most suitable between 〇, that is, when the temperature is lower than Τ-2. , Ρ-2> Ρ-1, at this time = is the object torn open the retaining belt, will appear in the appearance of the tape tearing open; when asked about Τ-2 in μ degree, at this time the sticker is torn open the security tape, Special coatings will be layered due to melting. The appearance of the color of the security tape is not necessarily the same: color difference, for identification to be torn open. At this high temperature, if the hose is not torn, the appearance of the tape does not change. 'After returning to normal temperature, the physical properties and trace function of the security tape will also be restored to the normal temperature condition. At this time, the security tape is torn open, and the room temperature display function is exhibited. Because of the cohesive strength and layer of the special coating "Reversible reaction to temperature _ 1. Reversibility of this trace function It can avoid damage to the security tape during the high-temperature transportation of the container, for example, and it is impossible to identify whether the sticker is actually unpacked. The special coating can represent the 丨·high temperature melting layer 2 according to different examples. Melting the color layer 3 to melt the dyed adhesive layer at a high temperature, one of the three types of sound. Of course, the experiment can only test the T-1 data of the conventional security tape. In the present embodiment, only the temperature of the τ_2 of the embodiment is known. The value is because the security tape in the test before the data of Example Τ-1 has not been measured has been destroyed. It is more correct to say that the T1 of the embodiment cannot exist. In fact, when the uncoated embodiment is specially coated The layer, but the same conditional security tape is tested. The T-1 value is greater than the value of τ_2 of the embodiment. Therefore, it can be reasonably confirmed that the temperature of the Τ2 of the present embodiment is 10 200812794 ▲ τ is lower than the temperature of τ-1 The purpose of creation has been achieved, and the technical idea has been confirmed to be true. Please refer to the second figure: This figure shows a schematic cross-sectional structure of the first embodiment, this embodiment includes a substrate 〗), the identification layer (2), the high temperature melting layer (3), the color layer (4), the adhesive layer (5), wherein the substrate (1) is a film exhibiting a transparent or translucent color, such as a ρ ΕΤ film The identification layer (2) is fully or partially printed with a release agent or a release agent under the substrate to be transparent or translucent; the high temperature melting layer (3) is made of thermoplasticity and The cohesive strength and the adhesion between the layers are temperature-reversible and are made of materials with low glass transition temperature (T/G), such as polyester esters and polyamine vinegar (p〇ly). Touch him), eav, ρ eucalyptus, rosin Ester, acryl resin, etc., or a mixture or compound of the above materials or a copolymer with other materials. The softening peeling temperature τ 〜 2 between the high temperature layer (3) and the coating to which it is adhered is lower than the failure critical temperature Τ-1 of the normal temperature trace. According to the experimental security tape 2 temperature is best between 40 C~90 °C. The construction method is partial or comprehensive, _ coating or printing on the color layer (4), the color is transparent or translucent. The color layer (4) is placed under the high temperature melting layer (3), and its color is brought into the substrate. Compared. The processing method is not limited, such as printing, coating, and electric iron. The sound tribute layer may be composed of a single layer or more than two layers of staggered or overlapped, for example, a color brush 'or a thin layer of molten metal (3) such as a sandwich structure generally lost between the two sound layers (3), but only the upper layer The color layer must be translucent, this: the method is equivalent replacement; the adhesive layer (5) is coated or affixed with pressure sensitive adhesive: under the color layer (4) for adhering to the article. In addition, you can use the release protection '11 200812794—(6) to temporarily adhere to the adhesive layer or apply a release agent on the substrate for convenient storage. The formulation of the first embodiment is as follows: substrate (1): transparent PET film having a thickness of 36//; identification layer (2): peeling force of the release agent to the substrate is 2 〇g/cm, and the coating film thickness is The printed pattern is a square lattice with a side length of 2·5 legs, and each of the geometrical patterns with a spacing of 2.5 mm is partially printed. Melting layer (3): The material is polyester. The T/G point is • 60±2°C, and the coating film thickness is 2//. Color layer (4): Gravure printing ink, coating film thickness 5#. Adhesive layer (5): Acrylic resin pressure sensitive adhesive film thickness 25//, tested by PSTC-1 test method, ambient temperature 23 ± 5 °C, stiffness 55 ± 10% RH, adhesion 650 ±70 g/cm, tested at soft peeling temperature T-2 (65 ± 5 °C), adhesion 230 ± 40 g / cm. The above formulation was tested after being made into a security tape. When the security tape is torn open at normal temperature, the normal temperature display function is exhibited. Then, the security tape _ is continuously heated and the security tape is torn open. Before the normal temperature trace function fails, the high temperature melting layer (3) has been melted and layered, causing the color difference of the appearance of the tape to generate a high temperature trace function, and its T- The value of 2 is approximately 65 ± 5 °C. The adhesive tape is continuously heated until l〇〇°C. At this time, if the security tape is not torn, its appearance does not change. After the temperature is restored to normal temperature, the security tape is torn open, and the normal temperature display function is displayed again. Before the test, without tearing off the security tape, even if the ambient temperature changes between -30 ° C and l ° ° C, the appearance of the tape does not change, and the trace function exhibits a reversible reaction. 12 200812794 ‘Refer to the second and fourth figures' The third figure represents a schematic diagram of the cross-sectional structure of the security tape at the normal temperature when it is torn off from the surface of the uncoated steel test plate (AISI 3〇4). Wherein the peeling force of the coating film formed by the identification layer (2), the high temperature melting layer (3), the color layer (4), and the adhesive layer (5) on the substrate (1) is below the range of the tear-opening mark (11) The adhesive layer (5) has a small adhesion to the object to be attached (7); rather than the range of the tear-opening mark (1)), the coating formed by the high-temperature melting layer (3), the color layer (4), and the adhesive layer (5) (1) The adhesion is greater than the adhesion of the adhesive layer (5) to the scented (7). Therefore, after tearing off the secret belt, the high temperature melting layer (3) is torn into a tearing melting layer (1)), the color layer (4) is torn into a tearing color layer (14), and the adhesive layer (5) is torn into tearing. The broken adhesive layer (15) forms a chromatic aberration in the area of the identification layer (2) on the appearance of the protective tape, and a tear-opening mark (11) is produced (refer to the fourth figure). The reason for this is that, according to the experiment, the thickness, elongation, tensile strength, tear strength, adhesion, etc. of each coating in the coating film will directly affect the peeling force, instead of the patent as in the past. The adhesion between the identification layer and the substrate described in the document. Referring to the fourth figure, this figure represents a schematic view of the appearance of the normal temperature trace effect after the tearing tape of the various embodiments of the present invention is torn from the surface of the article to be attached (7) when the temperature is lower than the normal temperature range of T-2. The tear-opened security tape has a tear-opening indication (11), which produces a normal temperature trace function, leaving a color trace on the appearance of the area after the sticker is torn away from the embodiment security tape (71). Please refer to the fifth and sixth figures. The fifth figure represents a schematic cross-sectional view of the security tape of the present invention, which is torn from the surface of the article to be attached (7) when the temperature is higher than the temperature of τ_2. Since the high-temperature melting layer (3) reaches 13 200812794 softening peeling temperature T-2 and melts and stratifies, forming a layered high-temperature melting layer (131), the appearance of the security tape forms a color difference different from the original appearance color (refer to Six maps). Referring to the sixth figure, this figure represents the appearance of the high-temperature trace effect after the tear-proof tape of the various embodiments of the present invention is torn from the surface of the article to be attached (γ) when the temperature is higher than the temperature range of Τ-2. . The high-temperature torn substrate appearance (51) forms a color difference that differs from the undrawn substrate appearance (61) color, resulting in a high temperature trace function. The appearance of the £ domain after tearing the embodiment of the security glue ▼ on the surface of the sticker leaves a soft peeling trace (72). The appearance of the unopened beauty material (61) and the appearance at normal temperature did not change, and the door was restored to the normal temperature. When the temperature returned to normal temperature, the security tape was torn open, and the normal temperature display function as shown in the fourth figure was exhibited. . An improved feature of the above embodiment is that the softening separation temperature Τ-2 between the high temperature melting layer and the substrate (1), the identification layer (2), or the color layer (4) is lower than the failure critical temperature of the normal temperature trace Τ- 1. Moreover, before the tear-off guarantee belt, the normal temperature trace function and the high temperature trace function will reversibly change with the change of the second production. 'Tear the security tape at the high temperature above Τ-2 ^ The security tape will be The specially coated high-temperature melting layer (3) is layered to exhibit the temperature-sensing function. When the temperature is below Τ-2, the security tape is torn open, and the poor temperature tape will have the function of the normal temperature trace with the tearing mark. The appearance of the tape did not change until it was removed. / Please refer to the seventh diagram: This figure is a cross-sectional dream of the second embodiment of the creation. The south temperature melting color layer (23) may be single or more than 3 layers 'local or comprehensive, coated or printed on the identification layer (p) and the odor material (1) 14 200812794, the color is contrasted with the substrate, It is made up of a color ink, which is made of thermoplastic, and its cohesive strength is reversible reaction with the adhesion between the layers. The material can be used as a modified agent for the ink' or Color body' or filler. For example, vinegar vinegar (p〇lyester), polyamide, EAV, PU resin, rosin Ester, acrylic resin, etc., or a mixture or compound of the above materials Or a copolymer with other materials, the softening peeling temperature T-2 between the high temperature melting color layer (23) and the coating to which it is adhered is lower than the critical temperature T-1 of the normal temperature trace. The temperature of T-2 is most suitable between 40 °C and 90 °C; the adhesive layer (25) is coated with pressure sensitive adhesive or adhered to the high temperature melting color layer (23) for adhesion to the article. Alternatively, the release protective paper may be temporarily adhered to the adhesive layer (25) or coated with a release agent over the substrate (1) for convenient storage. The formulation of the second embodiment is as follows: substrate (1): transparent PET film with thickness 36//; identification layer (2): peeling force of the release agent to the substrate is 20 g/cm, coating film thickness _ 1/ /, the printed pattern is a square grid with a side length of 2.5 _, each geometric pattern with a width of 2.5 faces, partially printed. High-temperature melting color layer (23): The main component of the ink is pigment, and the solvent is added to the carrier, which is made of polyamide. The glass transition temperature of the resin is 90±3° C. . Adhesive layer (25): film thickness 25/ζ, with PSTC-1 test, ambient temperature 23 ± 5 ° C, humidity: 55 ± 10% RH, adhesion 650 ± 70 g / cm. Tested at softening peeling temperature T-2 (70±3), adhesion 230±40g/ 15 200812794 cm 〇 tearing open the identification layer below the marking range, high temperature melting color layer, coating formed by overlapping turtle layer The peeling force of the film on the substrate is less than the adhesion of the adhesive layer to the object, rather than tearing off the peeling force of the coating film formed by the overlapping of the melted color layer and the adhesive layer under the dry circumference. It is larger than the adhesion of the Wei plastic layer to the attached object. The above formulation was tested after being made into a security tape. First, when the security tape is torn at normal temperature, the normal temperature display function is exhibited. Then, the security tape _ is continuously heated and the security tape is torn open. Before the normal temperature trace function fails, the high temperature melting color layer (23) has been melted and layered, causing the color difference of the appearance of the tape to generate a high temperature trace function. The value of -2 is approximately 70 ± 3 °C. Then, the security tape is continuously heated until the security tape is not torn, and the appearance of the security tape is not changed. After the temperature is restored to normal temperature, the security tape is torn open, and the normal temperature display function is exhibited.
