【発明の詳細な説明】 産業上の利用分野 本発明は、粘着付与樹脂の水性エマルジョンを製造す
る方法に関する。FIELD OF THE INVENTION The present invention relates to a method of making an aqueous emulsion of a tackifying resin.
従来の技術 従来、粘接着業界に於て溶剤型の粘接着剤が汎用され
てきたが、近年では労働安全衛生や省資源等の見地から
水性エマルジョン型へ移行してきている。これに伴い、
粘接着剤の構成成分たる粘着付与樹脂についても水性エ
マルジョン化が要望されている。2. Description of the Related Art Conventionally, solvent-based adhesives have been widely used in the adhesive industry, but in recent years, they have been shifting to aqueous emulsion types from the viewpoint of occupational safety and health and resource saving. With this,
A tackifying resin which is a constituent of the tacky-adhesive is also required to be an aqueous emulsion.
従来、粘着付与樹脂エマルジョンの製造方法は次の２
方法に大別される。一方はいわゆる高圧乳化法であり、
他方は転相乳化法である。前者は、粘着付与樹脂を有機
溶剤に溶解して通常60〜70重量％程度の溶液とし、これ
に適当な分散剤と水を添加して固形分濃度40重量％程度
の状態となし、次いで高せん断力乳化機（例えば高圧乳
化機）を使用し強制乳化を行い水中油型エマルジョンと
なす方法である。後者は、加熱溶融した粘着付与樹脂に
適当な分散剤と必要に応じ可塑剤、アルカリ等を添加混
合した後、水を添加して一旦油中水型エマルジョンとな
し、これに更に水を添加して転相せしめることにより水
中油型エマルジョンをうる方法である。Conventionally, the method for producing a tackifying resin emulsion is the following 2
The methods are roughly classified. One is the so-called high pressure emulsification method,
The other is the phase inversion emulsification method. In the former, the tackifying resin is usually dissolved in an organic solvent to form a solution of about 60 to 70% by weight, and a suitable dispersant and water are added to the solution to form a solid concentration of about 40% by weight, and then a high concentration. This is a method of forming an oil-in-water emulsion by forcibly emulsifying using a shearing force emulsifying machine (for example, a high-pressure emulsifying machine). In the latter, after adding and mixing an appropriate dispersant and a plasticizer, an alkali, etc., to the heat-melted tackifying resin, water is added to once form a water-in-oil emulsion, to which water is further added. It is a method of obtaining an oil-in-water emulsion by inversion.
しかしながら、前者方法では、溶剤を使用するため粘
着付与樹脂エマルジョンの製造時に尚、労働安全衛生上
の問題を有すること、また溶剤を減圧蒸留により除去す
る工程が必須となるため必ずしも省エネルギー的方法で
あるとはいい難く、更には溶剤を完全には除去しえない
ため粘接着剤として使用した場合に臭気の問題が生じる
などの欠点を有する。他方、後者方法では、粘着付与樹
脂エマルジョンの製造時に溶剤を使用しないという利点
があるため前者より優れた方法であるとされている。し

力、凝集力を著しく低下させるという不利があった。However, the former method is not always an energy-saving method because it uses a solvent and thus has a problem in terms of occupational safety and health during the production of a tackifying resin emulsion, and a step of removing the solvent by vacuum distillation is essential. However, the solvent cannot be completely removed, and it has a drawback that it causes an odor problem when used as an adhesive. On the other hand, the latter method is said to be superior to the former method because it has the advantage that no solvent is used during the production of the tackifying resin emulsion. However, with many dispersants used in the past, many tackifier resins have poor dispersion of the tackifier resin during the production of an aqueous emulsion, so that a large amount of coagulate is produced as a by-product, which lowers the yield and the workability at the time of production. The storage stability of No. 1 or the mixing stability with various acrylic emulsions and rubber latex was inferior to that obtained when the former method was adopted. Therefore, the applicable resins are usually limited, and general-purpose tackifier resins cannot be widely made into an aqueous emulsion, and this tendency is particularly strong in the case of a high softening point resin. There is also a method of adding a plasticizer component when emulsifying a high softening point resin, but since the softening point of the tackifying resin is substantially lowered, the heat resistance, adhesive strength, and cohesive force of the resulting adhesive are significantly improved. It had the disadvantage of lowering it.

ウム基を例示できる。In the present invention, it is essential to use the sulfonate represented by the general formula [I] as the dispersant. In the general formula [I], the group defined by R is a hydrocarbon residue having 4 to 18 carbon atoms, preferably 8 to 16 hydrocarbon residues. The hydrocarbon residue specifically means a linear or branched alkyl group or alkenyl group, and a styryl group or a distyryl group. Specific examples thereof include linear or branched butyl group, pentyl group, hexyl group, heptyl group, octyl group, nonyl group, decyl group, undecyl group, dodecyl group, tridecyl group, tetradecyl group, pentadecyl group, hexadecyl group. Group, heptadecyl group, octadecyl group, 5-decenyl group, 6-dodecenyl group, 7-tetradecenyl group, 9-octadecenyl group and the like. m is 1 or 2. If m is 3 or more, the hydrophobicity of the dispersant becomes large, the dispersibility decreases, and it is difficult to obtain a stable emulsion, which is not preferable. Further, the substitution position of (R) m is not particularly limited, but it is generally the ortho or (and) para position. The added mole number n of ethylene oxide is 1 to 3. When a dispersant with n exceeding 4 is used, the leaving stability of the tackifying resin emulsion and the mixing stability with the acrylic emulsion or the rubber latex decrease. In this case, if the amount of the dispersant used is increased, the stability can be improved to some extent, but the water resistance is significantly reduced, which is not preferable. Examples of the monovalent cation defined by M include alkali metal ions such as lithium, sodium, potassium and cesium, and ammonium groups derived from ammonia and various amines such as trimethylamine, dimethylamine, diethylamine and triethanolamine. .

Used at a rate of ~ 7 parts. If it is less than 3 parts, the dispersive power is not sufficient, and if it exceeds 10 parts, it is water resistant.
It is disadvantageous in terms of economy.
