Description of the Related Art Various techniques for preventing dripping and deformation of adhesives and sealants have been proposed so far, and typical examples thereof include polar groups such as special carbon black and colloidal silica. A method of mixing fine powder with an adhesive or sealant, or adding a small amount of glycerin to this to prevent the thing containing colloidal silica from losing thixotropy due to aging is proposed. I have.

観点から接着剤やシーラントの粘度が注目されており、
その粘度は一般に１０，０００〜１００，０００ｃｐｓ

原因になるので、肉やせの防止は重要な課題である。[0004] However, no proposal has been found for solving the problem of thinning after applying the sealant. As shown in FIG. 1, the sealant 2 used in the part where the tiles and the waterproof flooring materials 1 are joined together has the same height as the surface of the tiles and the waterproof flooring materials 1 immediately after construction, as indicated by the dotted line. But after some time, sealant 2
Causes a thinning phenomenon to form a depression as shown in FIG. Since water and dirt accumulate in such depressions, causing water leakage and dirt, prevention of thinning is an important issue.

に関する。SUMMARY OF THE INVENTION The present invention relates to an epoxy sealant having a volatile content of 2% by weight or less.
【０００７】前記揮発分の測定は、ＪＩＳ Ｋ６８３３
「接着剤の一般試験方法」６．４不揮発成分の項、表１
におけるその他の接着剤の欄に準拠して測定した。[0007] The measurement of the volatile content is carried out according to JIS K6833.
"General Test Methods for Adhesives" Section 6.4 Nonvolatile Components, Table 1
The measurement was performed according to the column of Other adhesives.

観点でエポキシ成分を選択する必要がある。したがっ
て、エポキシ成分として低分子量のものが混ってもよい
が、そこには自ずから制限が生じる。The epoxy component in the present invention includes glycidyl ether epoxy such as novolak epoxy, bisphenol F epoxy, bisphenol A epoxy and brominated epoxy; glycidyl ester epoxy,
Any type of glycidylamine-based epoxy, alicyclic epoxy, heterocyclic epoxy, etc. can be used for the time being, but when used as a sealant made of an epoxy resin composition, the volatile content is at most 2% by weight. It is necessary to select an epoxy component from such a viewpoint. Therefore, a low molecular weight epoxy component may be mixed as the epoxy component, but there is a restriction in itself.
【０００９】とりわけ好ましいエポキシ成分としては、
ビスフェノールＡ系エポキシが挙げられる。Particularly preferred epoxy components include:
Bisphenol A type epoxy is mentioned.

いて、硬化剤を選択する必要がある。As the curing agent, any one of amines, acid anhydrides, phenols, polyamide resins, imidazoles and the like can be used. However, the volatile content of the epoxy resin composition as a whole should be suppressed to 2% by weight or less. With that in mind, it is necessary to select a curing agent.
【００１１】その観点からいえば、硬化剤としてはポリ
アミド樹脂が好ましい。ここでいうポリアミド樹脂は、
主としてダイマー酸とポリアミンの縮合により生成する
もので、分子中に第一アミノ基や第二アミノ基を有する
ポリアミドアミン（ポリアミノアミドともいう）であ
る。From that viewpoint, a polyamide resin is preferable as the curing agent. The polyamide resin here is
It is mainly formed by the condensation of dimer acid and polyamine, and is a polyamidoamine (also referred to as polyaminoamide) having a primary amino group or a secondary amino group in the molecule.
