る。[Background technology 1] Organic polymer thickeners such as CMC and MC5HEC have traditionally been used to increase the viscosity of aqueous Nimark 5, which is used for painting construction materials, etc.; It is adsorbed by the pigments and latex particles contained therein, thereby forming a three-dimensional network structure and exerting a thickening effect. However, these thickeners have a problem in that their stability decreases when they are subjected to high shear in roll coaters, mixers, sprays, etc. when using paints.

＊の作業性が悪いという問題があった。As shown in Table tJII1, paints for construction materials generally use acrylic resin emulsion as the resin component. However, when using acrylic resin emulsion in this way, sonolum - It is necessary to use a large amount of montmorillonite, about 5% by weight, and the development of viscosity is slow, so when sonolum montmorillonite is used in powder form, it takes a day to reach the maximum viscosity. It may be necessary to mix (or add more sonorum/montmorillonite than necessary),
*There was a problem with poor workability.

The vinyl acetate resin acts as a thickening agent for sonoram/montmorillonite, and it is possible to develop viscosity in a short time by blending a small amount of sonoram/montmorillonite. Explain in detail.

。Water-based emuls:)M-based paints are prepared by mixing water with resin components, pigments, other dispersants, antifoaming agents, and thickeners. Sonorum montmorillonite (purified bentonite, colloidal sodium silicate) having shear properties is used, and vinyl acetate resin is further used as the resin component.

と考えられる。Sonorum montmorillonite has a structure in which a layer of silica and a layer of alumina are laminated, as shown in Figure 1 (,), and when this sonorum montmorillonite is dispersed in water, the structure shown in Figure 1 (b) is formed. It is thought that water molecules enter between the silica layer and the alumina layer and swell to widen the gap between the layers, thereby exerting a thickening effect. When vinyl acetate resin is blended as a resin component in the paint, the vinyl acetate resin acts as a thickening agent, and the thickening effect of sonorum montmorillonite is rapidly enhanced. This is because latex particles of vinyl acetate resin act on sonorum montmorillonite, and the carboxyl groups of vinyl acetate become adsorbed to the silica layer and alumina layer, as shown by the wavy line in Figure 1 (c). The spacing between the alumina and alumina layers has been further expanded, and the
This is thought to be because montmorillonite swells more rapidly.

１表の配合のものと同等の粘度となる塗料の配合を第２
表に示す。Due to the presence of vinyl acetate resin blended as a resin component, it is possible to obtain a thickening effect just by blending a small amount of Sonorum montmorillonite.
The reactivity of montmorillonite is increased, and the thickening effect can be quickly expressed, and the viscosity of the paint appears in a short time, so that the maximum viscosity can be obtained during the formulation of the paint. Here, when sonorum montmorillonite is used as the thickener and vinyl acetate resin is used as the resin component, the formulation of the paint that has a viscosity equivalent to that of the formulation in Table 1 is determined.
Shown in the table.
第２表のように、樹脂成分としてアクリル樹脂を用いる
場合にソノラム・モンモリロナイトを５重量％必要とし
たものが、樹脂成分として酢酸ビニル樹脂を用いること
によってソノラム・モンモリロナイト０．５型皿％以下
の配合でよくなるものである。As shown in Table 2, when using acrylic resin as the resin component, 5% by weight of sonorum montmorillonite is required, but by using vinyl acetate resin as the resin component, sonorum montmorillonite can be reduced to 0.5% by weight or less. It can be improved by mixing.

It is something.
