Abstract
The utility model discloses a kind of hot stripping tapes of discoloration, include successively protective layer by outside to inside, thermochromic layer, base, hot soarfing is from adhesive phase；The protective layer is water white transparency material；The hot soarfing, which is heated to from adhesive phase after certain temperature, can lose viscosity, and the thermochromic layer can change colour after being heated to certain temperature；The discoloring temperature of the thermochromic layer is slightly above the temperature that the hot soarfing loses viscosity from adhesive phase.It the advantage is that：Staff can rely on naked eyes judge whether adhesive tape is sufficiently heated, and prevent from occurring tearing and making adhesive surface damage due to not heating fully for adhesive tape, improve the reliability of work.
Description
Technical field
The utility model is related to a kind of hot stripping tape of discoloration, especially a kind of hot stripping tape of discoloration.
Background technology
Hot stripping tape is mainly used for resistance, inductance, capacitance, wafer, chip high accuracy positioning cutting/grinding.Hot soarfing from
Adhesive tape is made of a kind of special adhesive glue, has certain bonding force at normal temperatures, as long as being heated to the temperature of setting, glues
Resultant force disappears, and can be achieved with simply removing, does not stay residue glue, do not pollute adherend.It is realized certainly during production of electronic components
Dynamicization saves human and material resources, improves benefit.Existing hot stripping tape is mostly directly to be removed after heating, and lacks necessary instruction
Mode is easy the component fragile to some and damages.
Temperature-sensing color-changing material includes mainly the inorganic reversible temperature-sensitive material using metal oxide as representative, with triaryl methane benzene
Phthaleins is organic temperature-sensing color-changing material of representative, using cholesteryl liquid crystal as the liquid crystal type temperature-sensing color-changing material of representative.Heat discoloration
Material can occur the variation of color with the change of temperature within the scope of certain temperature.Inorganic material changes colour precision not
Height, and there is certain toxicity and corrosivity, and of low cost, convieniently synthesized, the discoloration wavelength of organic temperature-sensing color-changing material
The advantages that controllable, the discoloration cardinal temperature of reversible organic temperature-sensing color-changing material is -5 DEG C, 0 DEG C, 5 DEG C, 10 DEG C, 16 DEG C, 21 DEG C, 31
DEG C, 33 DEG C, 38 DEG C, 43 DEG C, 45 DEG C, 50 DEG C, 65 DEG C, 70 DEG C, 78 DEG C, transition interval can be accomplished from coloured to colorless state
Change.
Hot soarfing is widely used from glue in life, for common hot stripping tape, can be glued with common under room temperature
Film is closed equally to be bonded, need only heat when stripping and can simply peel film, it can be accurate at a certain temperature
Errorless stripping.
Utility model content
The main purpose of the utility model is to provide a kind of hot stripping tapes of discoloration indicating function with color.
To achieve the above objectives, the technical solution adopted in the utility model is：A kind of hot stripping tape of discoloration, from outside to inside
Include successively protective layer, thermochromic layer, base, hot soarfing is from adhesive phase；Protective layer is transparent material；The hot soarfing is from adhesive
Layer can lose viscosity after being heated to T1 temperature, and the thermochromic layer can change colour after being heated to T2 temperature；T2≥T1.
Preferably, the base is the thin slice or film using making such as the structures, such as PET of plastic tab or film,
It needs to bear certain temperature.
Preferably, 0 DEG C≤T2-T1≤20 DEG C.
The utility model has the advantage of：Staff can rely on naked eyes to judge whether adhesive tape is sufficiently heated, and prevent
Being torn caused by inabundant heating due to adhesive tape makes adhesive surface damage, improves the reliability of work.
Description of the drawings
Fig. 1 is the structural schematic diagram of a preferred embodiment according to the present utility model.
Wherein, protective layer 1, thermochromic layer 2, base 3, hot soarfing is from adhesive phase 4.
Specific implementation mode
It is described below for disclosing the utility model so that those skilled in the art can realize the utility model.It retouches below
Preferred embodiment in stating is only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.
Embodiment 1
The hot stripping tape of a kind of discoloration as shown in Figure 1, by outside to inside successively include protective layer 1, thermochromic layer 2,
Base 3, hot soarfing is from adhesive phase 4；Thermochromic layer 2 is triaryl methane phthalide-type material, becomes nothing after being heated to 70 degrees Celsius
Color, hot soarfing can lose viscosity after being heated 20 seconds at 65 degrees celsius from adhesive phase 4.
Protective layer 1 is polyethylene film.
Base 3 is the film that PET makes.
When need to tear adhesive tape when, to adhesive tape heat, continue after thermochromic layer becomes colorless keep 20 seconds after be torn off
Adhesive tape, at this time adhesive tape substantially completely lose viscosity, will not to adhesive generate damage.
Embodiment 2
The present embodiment it is substantially the same manner as Example 1, difference lies in：Protective layer 1 is polypropylene film.
Thermochromic layer 2 is fluorane compounds, and thermochromic layer 2 becomes colorless after being heated to 65 degrees Celsius；
From adhesive phase 4, the heating at 60 degrees Celsius loses viscosity to hot soarfing after 30 seconds.
When need to tear adhesive tape when, to adhesive tape heat, continue after thermochromic layer becomes colorless keep 30 seconds after be torn off
Adhesive tape, at this time adhesive tape substantially completely lose viscosity, will not to adhesive generate damage.
Basic principles, main features, and advantages of the present invention has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model the utility model also have respectively
Kind changes and improvements, these changes and improvements are both fallen in claimed the scope of the utility model.The requires of the utility model
Protection domain defined by appended claims and its equivalent.
