A spherical polymer of about 0.5 μm is dispersed in water. The constituent components are roughly divided into latex particles and an aqueous phase. Latex particles are formed of polymer particles and a protective layer, and the polymer particles may be simply composed of only a polymer, or may occlude a film-forming aid or a plasticizer. The protective layer is divided into an adsorption protective layer and a chemical adsorption protective layer. The adsorption protective layer is formed by adsorbing a surfactant or a water-soluble polymer in an aqueous phase. The chemical adsorption protective layer is formed by chemically bonding various hydrophilic groups to polymer particles.

It is composed of a solvent and the like. Among them, the surfactant having the surfactant and the water-soluble polymer maintain the adsorption equilibrium with those of the protective layer. The dispersion stability of the polymer particles in water is due to the function of the protective layer, and is classified into an electric double layer and a steric hindrance of the hydration layer depending on the water-soluble substance to be adsorbed and the hydrophilic group to be bonded.

樹脂等が挙げられる。[0004] Types of latex include natural latex, synthetic latex and artificial latex. Natural latex is an emulsion of a polymer produced in nature and is limited to natural rubber latex. The synthetic latex means an emulsion of a synthetic polymer produced by emulsion polymerization, and examples thereof include polymer emulsions such as styrene-butadiene rubber, acrylonitrile, butadiene, and vinyl chloride. Artificial latex is a part of a polymer that cannot be produced by emulsion polymerization, is produced by another polymerization method, and is artificially emulsified using an emulsifier, etc.
It is displaced. Examples of this type of latex include isoprene rubber, butadiene rubber, and urethane resin.

(2) Since the viscosity of the latex depends on the particle size at a constant concentration, the viscosity does not increase even if the molecular weight is increased. Therefore, it can be polymerized, and the performance such as adhesiveness can be improved. In addition, it is possible to increase the concentration by increasing the size of the particles.

In general, a polymer product has a volume resistivity of more than 10 13 Ωcm and a surface resistivity of more than 10 13 Ω, and its electrical insulation is one of the characteristics of the polymer product.

As a result of repeated research, the latex contains smectite clay minerals and further contains a certain percentage of condensed phosphate in the contained smectite clay minerals, thereby impairing the original characteristics of latex described above. It has been found that the object of obtaining a latex composition having excellent antistatic properties can be achieved without any problem, and the present invention has been completed.

る。Each layer of the crystal structure in the layered structure of such a smectite clay mineral forms a two-dimensional platelet having a thickness of about 1 μm, and the magnesium and aluminum atoms present in the platelet unit are lower. The platelet unit is negatively charged, isomorphically substituted with the valence cation atom. In the dry state, this negative charge is balanced with replaceable cations (usually sodium ions) outside the lattice structure on the plate surface, and in the solid phase these particles are bound together by Van der Waals forces to form a bundle of plates.

特徴である取り扱いの容易さが損なわれる。When this is dispersed in latex, replaceable cations are hydrated, the particles swell, and platelets are separated. In the ionic state, such as in water, the platelets have a negative surface charge and the ends have a positive charge. Under a condition where the surface negative charge is much larger than the edge positive charge, a stable sol state results. However, the repulsive force due to the surface negative charge decreases due to the increase in the particle concentration or the ion concentration, and a so-called card house structure is formed by suction of the surface negative charge and the edge positive charge, thereby causing a thickening or gelling. When such a phenomenon occurs, the ease of handling, which is a characteristic of latex, is impaired.

与える。On the other hand, when attention is paid to the antistatic property, the effect is exhibited as the concentration of the smectite-based clay mineral, which is the conductive particles, increases. In order to solve this conflicting problem, it is necessary to use a condensed phosphate which is a deflocculant in combination.
Although it is not certain, the condensed phosphate ion dissociates in the latex to generate a phosphate ion which is a large anion and a metal cation such as sodium or a cation such as an ammonium ion. The phosphate ions are electrically adsorbed to the positively charged portions at the ends to inhibit the formation of the card house structure, and thus act as a peptizer. For this reason, it becomes possible to add the smectite-based clay mineral to the latex while suppressing an increase in the viscosity, thereby providing an excellent antistatic effect.

記範囲未満では帯電防止効果が劣り、上記範囲より過剰

業性が悪くなる。In order to obtain a latex composition having excellent antistatic properties, it is preferable to contain 5 to 50 parts by weight of a smectite-based clay mineral per 100 parts by weight of the latex. If the amount is less than the above range, the antistatic effect is inferior. If the smectite-based clay mineral is contained in excess of the above range, the clay rises and the workability deteriorates.

定性が損なわれる危険があり好ましくない。The condensed phosphate is preferably contained in an amount of 3 to 10 parts by weight based on 100 parts by weight of the smectite clay mineral. If it is less than the above range, it is difficult to mix the smectite-based clay mineral at a high concentration, and the antistatic effect is poor. If the condensed phosphate is contained in excess of the above range, the dispersion stability of the latex may be impaired, which is not preferred.
