Problems solved by technology

However, there is a problem that when exposed to a high-temperature atmosphere such as fire, the flame-retardant film is peeled from the adherend due to the decomposition of the polymer component of the pressure-sensitive adhesive
However, there are problems in that the adhesive involves difficulty in re-adhesion, and time or heat treatment is required until fixation is achieved after application, so that fixation cannot be achieved immediately
There is also a problem that the adhesive is difficult to cut into sheets by punching, etc.
[0006] In addition, depending on the place where the anti-scattering film for glass is used, the film may be exposed to such a situation that the surface tends to have flaws
When the surface of the anti-scattering film for glass has striations, problems are caused in that: cracking of the film or the like occurs from the position of the striations; its anti-scattering property decreases; and its designability deteriorates.
[0026] In addition, depending on the place where the anti-scattering film for glass is used, various molds may grow on the surface of the film

Embodiment

[0512] Hereinafter, the present invention will be described in more detail by means of examples, but the present invention is not limited to the examples shown below.

[0513] It should be noted that a biaxially stretched polyethylene terephthalate film (trade name: "MRN38", manufactured by Mitsubishi Chemical Polyester Film) having a thickness of 38 μm on which a silicone-based release treatment was performed was used Each separator and cover separator used in each of the following examples were used. When performing various evaluations, these separators and the cover separator were peeled off as necessary.

Synthetic example 1

[0514] (Synthesis example 1) (Preparation of photopolymerizable slurry (A))

[0515] 90 parts by weight of 2-ethylhexyl acrylate and 10 parts by weight of acrylic acid were used as monomer components, 0.05 parts by weight of a photopolymerization initiator (trade name: "IRGACURE651", manufactured by BASF), and 0.05 parts by weight of a photopolymerization initiator (trade name Name: "IRGACURE 184", manufactured by BASF) was stirred in a four-necked separable flask including a stirrer, a thermometer, a nitrogen gas introduction tube, and a cooling tube until the mixture became homogeneous. Afterwards, nitrogen bubbling was performed for 1 hour to remove dissolved oxygen. After that, UV light was applied from outside the flask by using a black light lamp to perform polymerization. At the point when moderate viscosity is obtained, the lights are turned off and nitrogen sparging is stopped. Thus, a photopolymerizable syrup (A) was prepared as a composition having a partially pol...

Synthetic example 2

[0516] (Synthesis example 2) (Preparation of photopolymerizable slurry (B))

[0517]100 parts by weight of cyclohexyl acrylate as a monomer component, 0.05 parts by weight of a photopolymerization initiator (trade name: "IRGACURE651", manufactured by BASF), and 0.05 parts by weight of a photopolymerization initiator (trade name: "IRGACURE184", manufactured by BASF system) in a four-necked separable flask including a stirrer, thermometer, nitrogen inlet tube, and cooling tube until the mixture became homogeneous. Afterwards, nitrogen bubbling was performed for 1 hour to remove dissolved oxygen. After that, UV light was applied from outside the flask by using a black light lamp to perform polymerization. At the point when moderate viscosity is obtained, the lights are turned off and nitrogen sparging is stopped. Thus, a photopolymerizable syrup (B) as a composition having a partially polymerized polymerization rate of 7% was prepared.

Abstract

Provided is a shatterproofing member including a pressure-sensitive adhesive layer convertible into an adhesive layer, which allows adherends to be instantly fixed to each other, allows the adherends to be reattached to each other, is excellent in processability such as being able to be cut into a sheet shape, is not peeled from the adherends even when exposed to a high-temperature atmosphere such as one in a fire, and can express shatterproof property when attached to an adherend that is broken by combustion such as glass even if exposed to combustion during a fire or the like. The shatterproofing member including a pressure-sensitive adhesive layer convertible into an adhesive layer includes: a pressure-sensitive adhesive layer convertible into an adhesive layer; and a flame-resistant material, in which the pressure-sensitive adhesive layer convertible into an adhesive layer has pressure-sensitive adhesive property before being sintered, and has adhesive property after being sintered.

Description

technical field [0001] The present invention relates to a scattering prevention member including a pressure-sensitive adhesive layer (hereinafter, sometimes referred to as “pressure-sensitive adhesive layer”). Specifically, the present invention relates to a sinterable anti-scattering member including a pressure-sensitive adhesive adhesive layer, wherein the pressure-sensitive adhesive layer has pressure-sensitive adhesiveness before sintering, and it is After having adhesiveness, and the member can exhibit anti-scattering properties even when exposed to burning during fire etc. when adhered to adherends such as glass that are shattered due to burning, and when used for wood or plastic Shows excellent flame retardancy when treated with flame retardant. Background technique [0002] Conventional anti-scattering films for glass (see, for example, Patent Document 1) are pasted for crime prevention or to prevent glass from scatter due to impact. However, such a conventional an...
