Abstract

PURPOSE:To obtain a bonding adhesive capable of being handily used without adhering to a hand while exhibiting a sufficient adherent effect, by enclosing a given adhesive substance in specific capsules to form adhesive capsules. CONSTITUTION:An adhesive substance 1b such as casein, hide glue, starch glue, a urea resin, a melamine resin, an epoxy resin or a cyanoacrylate is enclosed in particulate, inorg. or porous inorg. capsules 1a in an arbitrary shape to form adhesive capsules 1. For example, the adhesive capsules 1 are sandwiched between adherends 2 and 3, which adherend 3 is then pressed to flow the adhesive substance 1b out of the capsules 1a through breakage of the capsules 1a or to let the adhesive substance 1b ooze out of the capsules 1a via the pores thereof, whereby the adherends 2 and 3 are bonded to each other at the bonding portions 2a and 3a thereof.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive bonding agent for bonding by utilizing polymerization and bonding of various materials.

[0002]

2. Description of the Related Art Paper was adhered using rice grains,
With the development of science and technology
New epoxies and cyanoacrylates from glue, casein, urea resin and melamine resin are used. The current situation is that not only conventional papers can be adhered but also all kinds of objects up to metal can be adhered and the adhesion can be done instantly.

[0003]

However, although it has come to be used in a wide range as described above, the liquid or semi-solid form is still the mainstream, and it is taken out from a tube at the time of bonding or from a container. It is projected and applied to the adhesive surface. For this reason, it may be unpleasant because it adheres to the periphery of the adhered part or to the hand and hinders the adhesion work, or the adhered adhesive becomes sticky. In addition, some medicines are harmful to the human body (eg, instant adhesives). I was feeling.

[0004]

The present invention solves such inconveniences and can be used easily without adhering to hands and while sufficiently exerting an adhesive effect, and does not provide a new adhesive bonding agent. And there is. That is, an adhesive bonding agent made of a capsule agent in which an adhesive substance such as casein, glue, starch paste, urea resin, melamine resin, epoxy type, cyanoacrylate type is encapsulated in an inorganic or porous inorganic hollow arbitrarily shaped fine particle capsule, Alternatively, an adhesive bonding agent in which an adhesion promoter such as water or a solvent is combined with the encapsulating material encapsulated in the capsule and another adhesive for applying,
Alternatively, it is composed of an adhesive bonding agent in which the capsule material and the capsule are combined in an arbitrary ratio.

[0005]

When the adhesive bonding agent of the capsule is used alone, when a slight force is applied for adhesion, the capsule is broken and the adhesive substance flows out or exudes from the capsule. And it is pushed further and adheres. When using a combination of capsules and encapsulant, in order to select and prepare the encapsulant that is suitable for the material to be adhered, the same procedure as when using the encapsulant alone is used The substance flows out or oozes out, and the accelerating agent such as water or a solvent that oozes out or oozes out from the encapsulant acts to improve the adhesive effect and makes the adhesion. Furthermore, when the capsule material and the adhesive substance to be applied are used in combination,
The encapsulant acts in the same manner as described above to enhance the adhesive effect of the pre-applied adhesive and adhere. In this way, the adhesive substance is encapsulated in the capsule, and when adhering, it flows out or oozes out between the adhering materials, so that the degree of adhering to the hand is reduced and the adhering can be performed comfortably. Particularly in the case of an instant adhesive, its effect is exhibited by encapsulating it in a capsule.

【Example】

(Example 1) In the figure, reference numeral 1 is a capsule agent consisting of inorganic or inorganic porous hollow spherical fine particle capsules 1a, such as casein, glue, starch paste, urea resin, melamine resin, epoxy system, cyanoacrylate system, etc. The adhesive substance 1b is included. Reference numerals 2 and 3 are joint materials made of arbitrary materials, and the capsule 1 is provided on the joint portion 2a. In use, when the capsule 1 is sandwiched and the bonding materials 2 and 3 are overlapped and the bonding material 3 is pressed, the capsule 1a is broken or oozes out from the pores and the adhesive substance 1b is adhered.
Flows out, and the bonding materials 2 and 3 are bonded at the bonding portions 2a and 3a. In addition, in order to provide the bonding substance 1b on the joint portion 2a,
It may be provided immediately before bonding or may be temporarily attached to the joint 2a with an adhesive.

(Example 2) Reference numeral 4 in the figure is an encapsulant composed of an inorganic or inorganic porous hollow spherical fine particle capsule 4a containing an adhesion promoter 4b such as water or a solvent. Reference numeral 5 denotes an adhesive to be applied, which is applied to the joint portion 2a of the joint material 2 and the encapsulant 4 is provided thereon. In use, when the encapsulating material 4 and the adhesive 5 are sandwiched and the joining materials 2 and 3 are overlapped and the joining material 3 is pressed, the capsule 4a is broken or bleeds from the pores to promote the adhesion promoter 4b.
Flow out to activate the adhesive 5 and bond the bonding materials 2 and 3 at the bonding portions 2a and 3a.

(Embodiment 3) This embodiment is an application of Embodiments 1 and 2 except that the capsule 1 and the capsule material 4 are combined and mixed at an arbitrary ratio and used, and the action and effect are also obtained. The description is omitted because it is almost the same as the first and second embodiments.

[0009]

[Effect of the Invention] As described above the present invention may also be used as any such types for enclosing the capsule, no effect by complete encapsulation. Therefore, there is no discomfort even if you touch it with your hands before use, and you can perform various bonding while you are using it with ease using a bonding material, and the effect remains the same even after long-term storage. It is a very excellent invention for industrial use because it has many features such as wide application range and wide range of applications.
