Abstract

PURPOSE:To provide the titled adhesive compsn. having excellent adhesion properties without emission of foul odor, prepd. by adding a reaction product of a dithiol and a diacryate monomer to a radiation-curing liquid oligomer having a radical crosslinking ethylenically unsatd. double bond. CONSTITUTION:A reaction product having no unpleasant odor peculiar to thiol is prepd. by reacting 0.1-1mol of a diacrylate monomer (e.g. ethylene glycol diacrylate or 1,6-hexane glycol diacrylate) to 1mol of a dithiol such as ethanedithiol or hexamethylenedithiol. The adhesive compsn. is obtained by adding 0.5-30pts.wt. said reaction product to 100pts.wt. radiation-curing liquid oilgomer having a radical-crosslinking ethylenically unsatd. bond in the molecule. The resultant adhesive compsn. has little unpleasant odor after irradiation to radiation.

Description

[Detailed Description of the Invention] The present invention is characterized by its great agility and strength! ! In the past, in pressure-sensitive viscous tapes, phw cohesive force, multiplication force, etc. Therefore, it was necessary to use it for plate bases with relatively high molecular weight and viscosity (that is, before natural rubber or synthetic rubber). For this reason, during coating, iL must be applied onto the substrate in a standard manner during the bathing process.

However, due to the drying process of the application (necessary long-term relaxation), the bath additives used for this purpose are volatile and flammable. In fact, there are many things that can cause negative effects on the human body, so one of them is that it can cause a fire, and the other is that it is a public notice issue of its own.

1. From the perspective of pollution prevention, the swamp agent recovery equipment that is considered unavoidable is extremely expensive and requires a lot of people to collect. Therefore.

In the 18th century, Riki Koji and others attracted attention to the four types of pressure-sensitive sanitizing agents that are known for their value-saving, energy-saving, and non-public use. As a countermeasure for eliminating bath additives, radiation-curing pressure-sensitive stimulants that use 1% mitotic oligomers, such as emulsion type and hot melt type, are gaining attention. The reason for this is that radiation-curing pressure-sensitive adhesives do not, in principle, contain organic bath agents, which are the key to the bath-type pressure-sensitive wound treatment described above, making them so-called bath-free. , or even if it does contain a small amount, (1) the curing reaction is fast (1 unit) because it uses radiation decoupling, which is an energy ray; (2)
) Since the curing reaction is progressing, the body life can be adjusted freely; (5) During production, it is necessary to avoid drying too thickly. However, even with this radiation-side hardened pressure-sensitive layer, there are the following drawbacks. In general, the russet (hardening) reaction progresses to a low saturation reaction due to the generated radicals, but the reaction rate is too fast and it is easy to cause excessive oxidation. (As a result, the glass transition point rises.) -f: Therefore, the formed film is brittle, and in the other case, the chassis shrinks and thick cracks τ occur. If you learn about the properties of the film in this state, there will be a big break. On the other hand, due to the excessive amount of Zhu Citrus, there is a local reaction between the loquats and the rats of the small saturated two-dimensional structure in the molecule, which progresses and gives a light result as a whole. It's a powerful result.

As described above, it is difficult to fully control the curing reaction and use a pressure-sensitive waste extractor to remove the liquid. Therefore, the Ministry of Invention et al.

In addition, the anti-LL of the vinyl group and the SH group competes with the chain reaction of the vinyl group and the vinyl thread, and it is presumed that the distance between the eccentric points of the kasurai film is different. .

However, it is a composition containing such a tessellated 8 π! Problems such as 71゜ sticky wounds (rumored to have been hardened by radiation) and the unpleasant odor of thiols were common. Therefore, we have made further efforts to investigate the use of ayu-mai, dithiol, and diacrylate monomers, and have finally published the present invention under the heading 5. .

The unpleasant odor of dithiol was caused by hydrolysis in the unreacted portions. There,
The thiol is generally made into a mold by washing with water, and the C1 removal rate is 10% by light.Also, the thiol reacts with the acroyl group on the vinyl thread.The result is 0 or more.

Therefore, it is possible to react and fragment the molecules on one side.

It has been found that Compound 9/J has almost no unpleasant odor even after 5 reactions and irradiation.

It is also possible to do so, but the key point is the irradiation atmosphere. However, since the generated cysicals or airborne fibers can avoid harmful effects, the core is directly exchanged with a small amount of active gas such as nitrogen based on the lifting platform, and the core is covered with a film on the skin.

Because it was a little fuzzy and the temperature did not change, it was stirred and gradually poured into 0.5 mol of 1.6 hexane difluoride (e) for 60 minutes.
At the end of the process, the temperature was raised to 80°C in a cabinet, and the strain was incubated for 6 hours. In the presence of a catalyst, 80% butyl and 20s of glycidyl methacrylate were used to form a lumpy mass of grapevine bamboo into an acrylic yarn composite body.
