Problems solved by technology

However, in the method for producing a polymer emulsion described in Patent Document 1, there is a problem that it is necessary to prepare an emulsion having a small particle size of the monomer mixture for the aqueous emulsion used. To manufacture polymer emulsions, a special dispersion device with high shear force is required, and the operation becomes cumbersome
However, the adhesive composition described in Patent Document 2 has a problem that, since it is a two-component type, a mixing step is required, resulting in poor mixing, etc.

Embodiment

[0064] Hereinafter, although an Example is given and this invention is demonstrated more concretely, It goes without saying that these Examples are illustrative and should not be limitedly interpreted.

Synthetic example 1

[0065] (Synthesis example 1) (B) Synthesis of silane compound

[0066]As shown in Table 1, add 3-aminopropyltrimethoxysilane (trade name: Z-6610, Toray Dow Corning Silicone Co., Ltd. )) 100 g, 3-glycidoxypropyltrimethoxysilane (trade name: Z-6040, manufactured by Toray Dow Corning Silicone Co., Ltd.) 276 g, and stirred at 50°C for 72 hours to obtain cyclocarbon nitrogen silicone. Regarding the obtained cyclocarbasiloxane, in FT-IR, it can be confirmed that 910cm -1 The nearby peak originating from the epoxy group disappears, and it can be confirmed that the 1140cm -1 Nearby secondary amine peaks, additionally, according to 29 Si-NMR can confirm that a new peak appears from -60ppm to -70ppm.

[0069] In Table 1, the compounding quantity of each compounding substance is shown by mass parts.

Synthetic example 2～3

[0070] (Synthesis Examples 2-3) Synthesis of Compounds Containing Hydrolyzable Groups

[0071] The complex substances were mixed at room temperature at the ratio shown in Table 2, and reacted at 80° C. for 3 days to obtain a hydrolyzable group-containing compound (1). In addition, the compound (2) containing a hydrolyzable group solidifies during the reaction, and a reactant cannot be obtained.

Abstract

Provided is a one-pack type water-based adhesive composition which suffers no yellowing and is excellent in terms of adhesiveness and durability. The one-pack type water-based adhesive composition comprises (A) an aqueous dispersion of a polyurethane resin and (B) a silane compound obtained by reacting a specific epoxysilane compound with an aminosilane compound represented by the following formula (2), the amount of the epoxysilane compound being in the range of 1.5-10 mol per mol of the aminosilane compound, at a reaction temperature of 40-100oC. (In formula (2), R7 to R12 are each a hydrogen atom or an alkyl group, R13 is a monovalent hydrocarbon group, R14 is an alkyl group, and b is 0 or 1.)

Description

technical field [0001] The present invention relates to a one-component water-based adhesive composition, and particularly relates to a one-component water-based adhesive composition excellent in adhesiveness and durability. Background technique [0002] In recent years, compared with solvent-based adhesives, water-based adhesives have various advantages such as adapting to labor safety and health problems, environmental problems, and saving resources. Type adhesives are converted to water-based adhesives. [0003] As an aqueous emulsification method of a curable polymer, Patent Document 1 discloses a method for producing a curable polymer emulsion, which includes: step (1), making a radically polymerizable monomer containing a hydrolyzable silyl group , the solution of the monomer that can be copolymerized with the monomer and the oil-soluble radical polymerization initiator is emulsified and dispersed in the aqueous medium containing the surfactant of 1.5~20 and the pH bu...
