Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a mixed curing resin. For more details 1
The present invention relates to an improved method for filling and packaging mixed curable resin compositions.

(b) Conventional technology Mixed curing resins include epoxy, acrylic, and urethane resins, and when a hardening agent and a main resin containing these resins are mixed, the resin can be cured even for a long time at room temperature. Since these resins harden within a day, they are used in many fields including the electrical and civil engineering industries for molding, painting, adhesion, sealing, etc.

When a mixed curing resin is mixed with a base component and a curing agent component, it immediately starts to harden even at room temperature and gels in a short period of time, so it is mixed immediately before use. Therefore, each component is packed and stored in separate containers.

Further, in the case of a mixed curing type resin, sufficient performance of the resin cannot be obtained unless the main component and the curing agent component are mixed accurately and sufficiently at a predetermined mixing ratio. Therefore, in order to avoid weighing errors and complicated weighing operations that tend to occur during use, a filling and packaging method is often adopted that corresponds to a predetermined ratio of each component.

For example, a base agent and a curing agent filled and packaged in separate containers according to fixed ratios are treated as a set, and the entire amount of both is mixed without weighing at the time of use.

Alternatively, one of the two components may be encapsulated in a capsule made of resin or glass, and this capsule may be enclosed in a container filled with the other component, and the capsule may be crushed in the container at the time of use, and the surrounding components may be mixed and used. Alternatively, the container containing the capsules is placed in the place of use, and both are crushed and mixed at the same time.

(c) Problems to be Solved by the Invention As mentioned above, various methods of packaging have been devised to prevent weighing errors when mixed curing resins are used. However, in a system in which the base agent and the curing agent are stored in separate containers, adhesion loss occurs when each component is poured out from one or both containers during use, and it cannot be said to be a perfect ratio mixing. Furthermore, although the capsule-enclosed format is effective for small volumes, it is difficult to crush the capsules for large volumes, and it lacks packaging efficiency and economy.

The present inventors have described a packaging method for such a mixed curing resin.
The present invention was completed after studying to solve the conventional drawbacks. That is, one object of the present invention is to provide a filling and packaging method that does not require weighing when using a mixed curing resin, allows highly accurate mixing, and is excellent in workability and economy during filling and use. be.

(d) Means for Solving the Problems The filling and packaging method for a mixed curable resin composition of the present invention is such that each component of the mixed curable resin composition is separated from the resin film cured by light irradiation in the same container. It is characterized by being filled with.

As the mixed curing resin used in the present invention, all conventionally used two-component mixed resins such as epoxy, acrylic, and urethane resins can be used.

Furthermore, as the resin that can be cured by light irradiation used in the present invention, conventionally used photocurable resins are applicable, and in particular, photopolymerizable photosensitive resins such as acrylic, epoxy, polyester, or polyurethane-modified resins are used. Acrylic resin etc. are preferred.

Materials for the container for the mixed curable resin composition used in the present invention include metal, plastic, glass, etc., and the material, shape, etc. are selected depending on the intended use.

The method for filling and packaging a mixed curing resin of the present invention includes filling a prepared container with either the base ingredient component or the curing agent component,
Next, fill a sufficient amount of photocurable resin that easily adheres to the container material to obtain the required film thickness, and immediately install a light irradiator on the resin surface inside the container and irradiate it with light, or apply light from outside the container. Irradiate light. The wavelength, irradiation time, intensity, etc. of the light may be determined in consideration of the type of photocurable resin, the type of sensitizer, workability per film thickness, etc. The photocurable resin hardens and forms a film within a few seconds to several minutes after irradiation with light, and the periphery of the film adheres to the container wall, meaning that the previously filled component composition is encapsulated at the bottom of the container. . Subsequently, the remaining other component composition is injected and filled. The filling amount at this time must be accurately weighed according to a predetermined appropriate ratio of the base agent and hardening agent. After that, the container is covered with an appropriate lid to complete the packaging. For containers made of resin or glass, the head may be heat-sealed instead of the lid.

To use the mixed curing resin filled and packaged by the method of the present invention, the diaphragm is broken in a container using an appropriate method, the contents are stirred and mixed, and then the required amount is poured out to the place of use. If the container is made of glass or plastic and has a particularly small capacity, it can be left in the package at the place of use, crushed and mixed with the container. For example, when installing anchor bolts,
The mixed curing resin filled and packaged in a glass container by the method of the present invention is inserted into the vertical hole together with the glass container.

Next, when the anchor bolt is pushed strongly while being twisted to crush the container inside, the mixed resin fills the periphery of the bolt and hardens, firmly fixing the bolt to the hole wall.

(e) Functions and Effects According to the method for filling and packaging a mixed curable resin composition of the present invention, after filling the first component, a photocurable resin is poured and a cured film is formed by irradiation with light. Therefore, since the position and shape of the diaphragm can be freely selected, the amount of resin filled can also be freely changed and adjusted. Once the cured film is completed, the second component is then filled, and the packaging is usually completed by capping the container or heat sealing it. The resin composition may be cured to form a cured film. By doing this, it is possible to avoid contact between the resin composition and the air and moisture in the space inside the container, and prevent deterioration and aging of the components. It also stops the flow of components and prevents unnecessary liquid shaking and resulting cargo collapse during transportation.

Furthermore, since the diaphragm is formed by photocuring, the workability is extremely quick, accurate, and reliable, and it is also highly economical.

When using the resin composition used in the packaging method of the present invention, each component is accurately weighed during filling, so the entire amount can be completely mixed in the proper ratio by simply crushing the diaphragm and mixing. However, now anyone can work easily, easily, and accurately.

Therefore, there are no failures due to measurement errors, and consistent and highly reliable planning performance can be obtained.
